Dong Qi looked at the patrol files that Ji Xun Zhouzhong was holding, and also looked at them.

As she watched, she was thinking about something.

Ji Xun listened to those words and asked casually: "What did you see?"

Dong Qi also knew that this was a test of himself and expressed his opinion.

"Well, what this patrol report should indicate is the abnormal phenomena that occurred in the research institute before the pollution leaked."

"Looking at the environmental conditions in the laboratory, our current timeline should be a few days after the pollution outbreak. The leak has now been confirmed, so there may be some special situation around 12:40 midnight. .Now, it’s about five hours before that time.”

"As for the T64 cabin, it is on the first floor. It may not be an important place, but there must be something special that led to the initial signs of local energy anomalies."

"One more thing is that Dr. Victor. He may be a key figure."

After Dong Qi finished speaking, he glanced at Ji Xun with uncertainty in his eyes: "Am I right?"

Ji Xun smiled, "Yes."

This Miss Qiqi can design her own mechanical armor, and her talent is not low.

Ji Xun himself could only see so much of this information.

He thought of something and added something: "Yeah. One more thing. Obtaining clues through this unusual way may trigger some hidden plots."

Dong Qi cast a doubtful look as he listened, "Oh?"

Ji Xundao: "As far as the current situation is concerned, there are very few hunters who are proficient in Talungu. But it is not impossible. Since this kind of plot item appears in the space, and not anything else, it must be useful."

When he said this, his eyes were blazing, and he said: "It is very possible that space has prepared it for people like us who can understand the Talun ancient script. Accordingly, if we follow this clue, it may be very difficult. high."

This is another joy of extradimensional space.

Many spaces hide some "Easter eggs" that you will never discover if you don't discover them.

Once discovered, it will be a surprise.

After saying this, Dong Qi's face had long lost the previous anxiety about the unknown. Instead, he was filled with expectations and asked: "Higher than A-level?"

It seemed that with this guy, there was nothing to fear.

Ji Xun's eyes were deep and he said: "Yes. Judging from the current exploration level, the possibility is not small. Those guys triggered the A-level plot, but it was only on the three floors above and below. And the exploration level was less than 90 %, it’s clear they didn’t discover where the source of the contamination was.”

It is very rare to encounter an extradimensional space where A-level or above plots can appear.

The high upper limit of space difficulty means greater challenges and greater opportunities.

This was also one of the most important reasons why he selected the "1981 Mechanical Research Institute" from various spaces before entering.

Dong Qi's expression immediately brightened when he heard this: "Where to go?"

Ji Xun smiled and shook his head, "The clues we have now can't support us to challenge that level of difficulty. At least go to the third floor and have a look first."

Dong Qi nodded: "Yes."

Not long after, the two came to cabin T64.

Ji Xun partially transformed into a werewolf, sniffed the smell in the cabin, and immediately determined something, saying: "The first-order A-level [Corrupted Giant Demonic Ape King] we killed before came out of this cabin. "

Dong Qi also understood something immediately and said: "In other words, this cabin is more polluted than other cabins, and that is why the disaster occurred?"

"Um."

Ji Xun nodded, and the two of them started looking around in the cabin.

However, this cabin of more than 20 square meters can be seen clearly at a glance, and there is nothing noteworthy.

Ji Xun thought of the space in 407 before.

Not all walls are regular objects that cannot be broken.

He took out his firearm and fired several shots around the wall.

Dong Qijian didn't understand what he was doing at first.

But seeing that the bullet marks on one of the walls had not disappeared, she immediately understood: "Is this wall destructible?"

Ji Xun's expression showed no surprise, and he nodded and said, "Yes. But we can't destroy it here."

He walked over and tried it at the bullet mark, and his sharp wolf claws could only scratch out a little white mark.

With this kind of intensity, even if the whole house is filled with bombs, it will not be destroyed.

Then Ji Xun put his ear against the wall, knocked on it, listened carefully to the thickness and echo, and then said: "There are gaps in the wall, coming from below. This should be the reason why this cabin is heavily polluted."

The werewolf's keen hearing allowed him to hear the abnormal echoes in the wall.

"oh?"

Dong Qi also imitated him and listened, but didn't hear anything. He pursed his lips, apparently not hearing anything.

Ji Xun smiled and said, "Let's go to the second underground floor."

There was nothing to explore on the first floor, so the two of them went from the destroyed elevator to the second underground floor dozens of meters below.

As soon as I came down, I saw a lot of explosion marks in the corridor.

Dong Qi squatted on the ground and looked at the traces left by the explosives. He dipped his hand into a little powder and quickly concluded: "U3 military anti-armor bombs are difficult to obtain on the black market."

Hearing this, Ji Xun looked at the corridor in the distance with traces of bombs all the way, and chuckled: "Those guys are well prepared. We didn't even have time to clear the battlefield, and we couldn't push it quickly with bombs, which saved us." A lot of trouble.”

But he sniffed and smelled the strong smell of blood in the air, and in a blink of an eye he changed into a werewolf form, "There are very powerful monsters on this floor. It seems that those guys have not been dealt with."

Dong Qi also nodded.

The two of them walked all the way.

Not long after, they saw human corpses on the ground.

It was a severed arm with a military exoskeleton.

Ji Xun picked up the severed arm and frowned when he saw the smooth but slightly carbonized cut.

This was no ordinary sword wound.

Dong Qichu was also confused and said: "There is no magic power left. It seems to be a mechanical equipment that can cause extremely high temperatures."

Ji Xun thought of the magic lightsaber displayed by the Cao family in Innocence City before, and said solemnly: "You can cut open the mecha Qiqi with one sword, so be careful."

"Um."

Dong Qi nodded.

The mechanic's defense is strong, but there is a critical value.

If the monster's attack really exceeds that critical value, the machine will be no different from paper, but a burden.

The two didn't walk long before they saw the remaining parts of the body.

The head was cut off.

The cut is still the smooth carbonized cut.

Ji Xun recognized the identity of the corpse at a glance. It was the guy named "Luo Bo" among the four second-level people who came in before.

Dong Qi looked at the mechanical exoskeleton and said solemnly: "The 'War Bear Ninth Generation Mechanical Exoskeleton' produced by the Morgos Military Factory has stronger armor defense than ordinary second-level card masters. It is already considered to be of the highest quality on the market. A single soldier has become a skeleton."

The strength and equipment were not weak, but the fact that he was killed so easily showed the strength of the monster.

Seeing the corpse, Ji Xun glanced at the traces of battle around him out of the corner of his eye.

The image of two shadows fighting fiercely in the corridor automatically appeared in my mind.

Every footprint corresponds to every displacement.

Each row of projectiles corresponds to the monster's dodge route.

There were no obvious signs of collision. It looked like this guy was fighting a ghost-like guy throughout the entire process.

Ji Xun thought of this and directly judged: "The monster may be a deformation of a human being, and it has very good sword skills. Its strength should be around second-order B level. It is not big in size, and its agility attribute is exaggerated, above 40. . The strength of the legs is very strong, and the upper limbs are average. And there is also a very special mechanical knife."

Dong Qi was slightly surprised. This guy just looked at the traces at the scene, as if he already knew so much information?

But it sounds like the agility attribute has exceeded 40, which is a level that most third-level card masters cannot catch up with.

This kind of agile monster is really tricky for a relatively bulky mechanic.

But when Ji Xun saw this, the corner of his mouth curved up: "You may have a useful weapon."

Dong Qi didn't follow the circuit in his brain and said in surprise: "Huh?"

Ji Xun smiled softly and said: "Since it has appeared, then to kill this disaster, as long as the clearance evaluation is high enough, the probability of drawing this knife or the blueprint is very high."

This kind of mechanical equipment can hardly be brought out of another dimension.

However, it is possible to draw cards at settlement.

He has experienced so many different dimensions and has figured out some settlement rules.

As long as they have been encountered in space and killed.

Then there is a high probability that the props or drawings in the relevant plot will appear in the settlement card pool.

Dong Qi thought for a moment and then suddenly realized: "So...are you going to kill it?"

She was very interested in the kind of knife that could cut through mechanical bones with one blow.

But... it's very dangerous.

"Um."

Ji Xun nodded.

It’s not just about settlement evaluation, there’s more to it.

He said: "If I guess correctly, this monster may be the most critical disaster on the second floor. If you want to get key clues, you can't avoid this monster."

Those guys from the Iron Hands couldn't kill this monster before, but that doesn't mean he can't kill it.

"."

Dong Qi looked at the corpse on the ground, originally worried that the monster was too dangerous.

But looking at the figure in front of her who was walking steadily forward facing the darkness, her eyes turned strange and she followed him without hesitation.

There are many marks in the corridor, and it can be seen that the group of people who went down before left in a hurry.

It's pretty much just dropping bombs all the way and charging away.

Four more bodies appeared on the road with various wounds.

There are some other aberrations on this level.

Ji Xun and the two walked slowly and leisurely.

Most of the previous minions were attracted to the first floor, and the second floor was quite empty.

Along the way, they only encountered a few aberrations that were not too difficult to deal with, and they killed them casually.

But I don't know if it was just luck. I walked around the second floor for most of the time and didn't encounter that very troublesome person.

As the two walked along, they picked up some research materials along the way, and also placed a few bombs to block the intersection.

As they walked, the two came to a locked office door.

This is just below cabin T64 on the first floor.

Ji Xun looked at the door in front of him, with a sinister smile in his blue eyes: "It's right here."

The atavistic werewolf's sense of smell allowed him to clearly smell the scent of the monster inside.

This is an alloy password door.

Without specific access control identification, it cannot be opened at all.

I don't know why, but standing in front of this door, Ji Xun always feels very familiar.

It was as if we had met an opponent who could understand each other on a soul level.

He also knew that the guy inside also noticed someone outside the door.

The other party is also waiting.

Waiting for a chance to raid.

The two sides faced off for a moment through a door, with an invisible aura facing each other tit for tat.

Dong Qi on the side also sensed the dangerous aura, his eyes were solemn, and he was quietly on guard.

Ji Xun tilted his head and looked for a moment, with a strange smile in his eyes, and muttered: "This guy seems to know that he can't be beaten, so he doesn't dare to come out."

As he spoke, he slowly stretched out his hand provocatively, deliberately exposing a flaw.

This move was like a balance being broken.

He moved first and lost half the move.

But the moment he was about to touch the door handle, the door opened with a "crash"!

A black shadow rushed out quickly, and at the same time a flash of red light arced through the air.

Ji Xun only had a sneer in his eyes and quickly retreated.

But even with such a quick reaction, the red light slashed at his wrist with one strike, accurately breaking several tendons.

"What a tricky knife skill!"

Just by meeting him face to face, Ji Xun understood the strength of this monster.

With such an exaggerated speed, it’s no wonder that the previous corpses couldn’t react.

And more importantly, the knife in this guy's hand actually broke his defense with just one blow?

It's not sharp, but an extreme high temperature that cuts through the body's protective spell and muscle layer.

This power is comparable to a relic-level weapon.

Normally, this knife would have disabled a person's hand.

But Ji Xun disagreed.

The pain didn't make him feel any weird at all.

Green light gushed out from the wrist, and the scorched fracture healed visibly.

Taking a closer look, there was a monster with a rabbit head and a white coat on the opposite side.

【Crazy Bugs Bunny】

Detailed explanation: A second-level B-level disaster; it was originally a death-row prisoner experimental subject imprisoned in the research institute. He was a perverted murderer during his lifetime; he was later contaminated and transformed into a monster; be careful, its knife is very sharp.

Ji Xun stared at the monster and muttered: "It turns out to be a rabbit."

This was the first time he had seen an aberrant creature look so "cute".

The rabbit monster also looked at the werewolf in front of him with his scarlet eyes, tilting his head as well.

Crazy eye contact,

Neither side has any fear of death.

Only the crazy idea of ​​killing the other party came out at the same time!

Ji Xun grinned, kicked the ground with his feet, and with a "pop" sound, he stepped into the air and rushed away.

The red-eyed rabbit monster also rushed forward with the strange short knife in hand.

In the blink of an eye, two extremely fast shadows met and merged in various moments in the air.

Whenever that weird red knife comes into contact with Ji Xun's fur, it will cause a bloody mouth.

Moreover, the angle of attack is very tricky, whether it is the neck or the heart, head and other vital points.

Knives are deadly.

For any second-level card master, this is almost a mistake that will lead to death.

However, there was no fear of death in Ji Xun's eyes, and he faced the blade directly.

The monster's agility attribute is high, and he's not low either!

The monster had gained a slight advantage in the sneak attack before, but after "Cell Activity Boiling" recovered from its arm injury, the two sides were at the same starting point again.

At this moment, Dong Qi had already blocked the door, and it was impossible for him to escape back.

Ji Xun's attack was not just wolf claws, there was also a scalpel shining with cold light flying around his body.

The rabbit's sword skills were very exquisite, but Ji Xun's face-mounted attack style, regardless of the injury, didn't give it any room to move.

It was during this encounter that the rabbit's collarbone was pierced with a single blow of the scalpel.

Fortunately, the injury was not fatal. The rabbit retreated and wandered away, and Ji Xun pursued him.

A tall gray wolf chased a rabbit and ran wildly in the dark corridor.

Knowing that this was a highly sensitive monster, Ji Xun and the two set up some traps in advance.

One chased and the other fled, and the sound of explosions was endless.

Ji Xun knows the location of every bomb and can avoid it skillfully.

That rabbit monster is just like thunder all the way.

It is like sharp glass, although it is deadly, its body is also very brittle.

And the speed is not as fast as the werewolf body.

From the moment it first met and failed to kill Ji Xun, the outcome was already doomed.

The chase on the second floor of the institute ended shortly after.

Not long after, Ji Xun, who was covered in blood, walked back steadily with the corpse of a rabbit monster in his hands.

Dong Qi looked relieved when he saw it was Ji Xun.

She, a mechanic, couldn't help at all in the kind of battle just now.

Ji Xun walked over and threw the dark dagger still stuck to the burnt flesh: "Go on."

Dong Qi took a look and saw that it turned out to be the [Magic Mechanical Melt Knife] in Rabbit's hand before!

It doesn't glow when it's charged, and looks ordinary.

Ji Xundao: "This is a plot prop and cannot be taken out of the space. It can be charged for ten minutes, so don't use it lightly now. This thing should be a key prop."

His own attack methods are sufficient, this knife is dispensable.

But Dong Qi lacks something to deal with high-level monsters.

The most important thing is that this thing is hot to the touch. Once it is charged with energy, it will be impossible to hold it with the physical body!

Even for this rabbit monster, the flesh of the hand holding the knife was completely stuck to the handle.

But this thing is perfect for mechanical warriors.

Dong Qi looked at this black technology short knife and couldn't put it down instantly: "Yeah!"

When she thought about Ji Xun's previous remarks that drawings might be produced in the settlement lottery, she was even more excited.

Ji Xun saw through her joy and added: "The probability of getting this blueprint is very low. Even if you complete the A-level mission, you can only gamble on luck."

He estimated that the quality of the drawings converted into extraordinary materials would probably be gold items.

The probability of being drawn will never exceed 5%.

The prerequisite is that they must clear the current A-level difficulty.

Dong Qi instantly understood the meaning of his words, "So, you want..."

Now that there are clues, Ji Xun naturally wants to challenge the more difficult hidden plot.

But we have to start from reality.

He was not too ambitious and said, "Let's go and see what clues there are in this room first."

Dong Qi listened and nodded seriously: "Yes!"

At this point, how come she didn't see that Ji Xun was a super guy who was exploring extra-dimensional space?

Not only is his combat prowess ridiculously strong, his ability to think through situations is also far beyond anyone's reach.

He always has a calm and calm look on his face, which is a kind of confidence that is inexplicably convincing!

But just when Ji Xun turned around, Dong Qi saw something unusual and frowned: "Ji Xun, you seem to have gray hair."

She clearly remembered every detail of Ji Xun's body, and the strand of white hair on her temples was particularly eye-catching at this moment.

When Ji Xun heard this, he said indifferently: "Oh. It's okay."

Dong Qi was not stupid, and asked: "Is it caused by the secret recovery method you used before?"

Ji Xun nodded and said indifferently: "Yeah."

"Cell Activity Boiling" gave him a powerful body that could hardly be killed by a single blow.

This Fifty-Two Demonic God Forbidden Technique is so powerful, it is appropriate to pay the price.

Ji Xun's mentality was very peaceful.

The more brilliant life blooms, the faster it withers and fades. This is the law of the universe.

Dong Qi looked at it, frowning with worry in his crystal eyes.

But she didn't have any good suggestions, and looking at Ji Xun's attitude, she swallowed what she wanted to say.

The two walked into the cabin where the rabbit monster had been hiding.

This is obviously a cabin for research institute staff.

As soon as I came in, the place was a mess of blood and flesh.

There was an inhuman corpse on the workbench, its internal organs had been eviscerated, and it looked like it had been eaten by a monster.

The air was filled with the smell of rotting flesh and blood.

However, both Ji Xun and Ji Xun were used to seeing bloody scenes, and they didn't feel any discomfort at all.

It would be impossible to kill that rabbit monster without several top level two enemies surrounding it.

Currently, the Lion Heart Family is still searching for information, so Ji Xun and the others take the lead.

This is a cabin that no one has ever been to.

There is no record of this in the intelligence.

The two rummaged around and found a large amount of research information this time.

Ji Xun was sure that this room was directly related to the subsequent plot, so the two of them did not miss any corner.

Finally, an experimental diary was found in a secret box.

"On April 29, the experimental data showed obvious signs of being out of control, but Dr. Victor insisted on continuing."

"May 3rd was a very bad day. There was uncontrollable pollution in the Titan Mechanical Heart. We chose to hide it from our superiors. I don't know if it was right or not."

"On June 1st, experiment number #789 was injected with five times the amount of medicine. The subject's wailing lasted for eight hours and then failed. All the subjects who were fused with the mechanical heart were deformed and died. The data was too complex to be analyzed. The degree. Dr. Victor locked himself in the laboratory all night and calculated it. He firmly believed that it was just a normal fluctuation, but a large number of experimental subjects in the institute had shown signs of distortion. I suspect that Dr. Victor has also suffered from mental distortion. "

"On June 2, the situation has exceeded the level that the research institute can handle, and the disaster level is S. I know I should do something. I have no regrets in dedicating myself to science. But if the outcome turns into a disaster, I hope that people outside can Know what happened. I left a lockbox"

"."

This is also a diary translated by Space Will.

This directly proves that this is a very important clue.

Ji Xun quickly scanned the contents of the log, then smiled and said to Dong Qi: "I have the password."

That B-level mission had a lockbox that no one had ever opened.

It can be opened now.

Dong Qi will also smile heartily.

The key "password" was found.

Ji Xun and the others did not linger on the second floor and went to the third floor of the research institute.

This research institute has a very complex structure and complete security facilities.

Normally, if you want to go to the third floor of the laboratory, you must open the multi-alloy mechanical door.

If you want to find clues bit by bit, it will probably take a lot of time.

But fortunately, the guys from Steel Hand who went down first seemed to have the password to open the door. Ji Xun and Dong Qi walked along smoothly.

After arriving on the third floor, Ji Xun also discovered that the structure of the entire research institute was in the shape of an inverted pyramid.

The further down you go, the smaller the building area becomes.

After coming down, Ji Xun also became very cautious.

This layer is completely an intelligence blind spot.

The monsters on the previous level are already life-threatening, so there must be even more exaggerated monsters on this level.

The laboratory was empty. After passing several rooms in a row, there were only some broken instruments and petri dishes.

There was green solution flowing everywhere and body parts.

Soon, the two followed the traces of the battle and found a room. They saw a huge scrapped mecha in the corner.

Dong Qi recognized it at a glance: "Giant Generation VI heavy mecha?"

Ji Xun also felt familiar.

Although it was different after modification, he could also tell that it was the strongest single-soldier mecha in the federal military currently carried by Young Master Kak that he had seen in Honglou before.

But a mecha like this was beaten alive and scrapped?

During the previous stop at Honglou, Qin Ru had easily destroyed many objects.

But she is a legendary powerhouse after all!

But now we are in a different-dimensional space that restricts second-level card masters!

This giant mecha is known as the most powerful individual combat machine. It is difficult for third- and fourth-level professionals to deal with it. What can turn it into a pile of scrap metal?

And it's not just this armor, there are several corpses wearing mechanical skeletons nearby that have been twisted into twists.

It shows how terrifying the monster’s power is!

In an instant, Ji Xun's hair stood up, his five senses were exposed, and he listened carefully to every corner.

But the strange thing is that he turned into a werewolf and didn't smell the monster's breath?

Ji Xun immediately judged what was going on and said to Dong Qi who was beside him: "I didn't smell any biological scent. It might be a mechanical monster. When the time comes, be careful and act according to the situation."

Dong Qi also nodded: "Yes."

Ji Xun walked a few steps and then thought again: "We have seen fourteen corpses, and there are still six people alive. Is there really a 'safe house'?"

Dong Qi was also extremely smart and thought of something.

The two of them started searching in this laboratory.

Those guys left their scent all the way, and Ji Xun found them easily.

It was separated by a glass wall and had a code-locked door next to it.

In the glass house, the six people looked at the sudden appearance of Ji Xun and the two, and were stunned: How could anyone come to the third floor alive?

For a moment, they also thought that these two must be the hidden masters who caused the abnormal team distribution before.

Looking at Ji Xun's highly recognizable throwback werewolf body and Dong Qi's cool Gunnir Orkin armor, he immediately guessed their identities.

The six people, headed by Deputy Captain Ke Sen, looked at the two people outside the glass coldly through the glass.

Being able to reach the third level is truly surprising.

But that’s about it.

No one knows better than them how terrifying the monster outside is.

Ji Xun tilted his huge wolf head and looked at the six shocked and then indifferent people inside, and then grinned.

He didn't ask anyone to open the door to the safe house.

Because he knew it would be useless to speak.

There's no way these guys are opening the door.

Dong Qi frowned under his helmet.

Seeing that several people inside were wearing the Federation's most advanced mechanical armor, but they were all hiding in the safe house, it meant that there was an absolutely fatal crisis hidden on the third floor.

But without the password, this safe house cannot be entered.

However, without thinking much, Ji Xun's voice came from beside him: "There must be a way to open this safe house. See if there are any clues about the hidden password nearby. For example, some special patterns, regular numerical values, and formulas .”

As he spoke, his eyes began to roam around the safe house carefully.

The brain is also running at a high speed like a computer, searching for all the information previously obtained.

Again.

The purpose of the existence of extradimensional space is not to kill all adventurers.

Within the limited difficulty, no matter what the desperate situation, there must be a chance to break the situation.

There seems to be an unmatched monster on the third floor of this research institute.

And the safe house is a glimmer of hope left in this fatal situation!

Then there must be a way to open it.

Hearing Ji Xun's still calm words, Dong Qi on the side also came to his senses instantly, and sighed again in his heart: Sure enough, this guy can remain absolutely calm at all times.

As soon as the thought flashed, she stopped thinking about it, and her eyes quickly searched for clues.

Special patterns, regular numerical values, and formulas.

Ji Xun's reminder also flashed through Dong Qi's mind.

Ji Xun'er Guo trembled slightly, always paying attention to capture the abnormal movements in the laboratory.

There seemed to be many independent thoughts in his mind helping to process the information received by his eyes.

And coincidentally, one of the thoughts saw the grid of the vents above the laboratory. After looking at it for a while, he discovered that it was not completely regular!

But after looking at it for a while, I had no clue. I vaguely felt that it contained some mathematical rules.

Ji Xun said: "Qiqi, look at the ventilation grid."

This is a mechanical extra-dimensional space, and Dong Qi is more proficient in mechanical knowledge than he is.

Sure enough, when Dong Qi took a look, his pupils blurred and he took the grid into his field of vision, and immediately found that it looked like rows of numbers.

She has seen it!

It was in ancient books before!

Dong Qi exclaimed: "This is the 'Hohenheim Mechanical Code'! Give me some time, I can calculate it!"

Sure enough?

Ji Xun also chuckled after hearing this.

However, at this moment, his expression suddenly changed, "Boom", "Boom", "Boom". The floor seemed to shake.

Ji Xun tilted his head, and a silver mechanical gorilla rushed over!

The six people in the safe house looked at their behavior and sneered.

They already knew that the difficulty on the third floor of the institute was not to decipher any code.

But to live under the hands of that monster!

【Mechanical Gorilla No. 013】

Detailed explanation: A second-level A-level disaster; a mechanically modified experimental subject, 95% of its body has been mechanically modified, and has invincible defense and absolutely terrifying power; it was originally dead, but the distortion brought it back to life;

The moment he saw the monster, Ji Xun was hit by the monster. As he flew backwards, a mouthful of blood spurted out.

So strong!

It's ridiculously strong!
