At the end of the stairs is an artificial metal gate.
This door cuts off the path between the stairwell and the lower ground floor.
Under ideal circumstances, the metal gate would isolate the air flow inside and outside the door, sealing the poisonous gas emitted by the undead creatures in the tomb passage of the catacombs.
But now, there are signs of corrosion on the metal gate.
There are a lot of fringe-like corrosion lines on the door seams and door hinges.
A faint trace of yellow-green poisonous gas is emerging from these damaged areas and flowing upward along the corridor of the stairwell.
Sergeant Mars raised the coal lamp and shined it on the door panel.
A weak but somewhat dazzling light is reflected from the corroded place.
"...The corroded area is very smooth and has no burrs. It should have appeared in the past ten years or so."
Sergeant Mars muttered something.
He turned his head and looked at the corporal behind him:
"When was the last time this door was serviced?"
The corporal took out a diary, flipped through a few pages, and found the exact date:
"Sir, the last maintenance was 21 days ago."
Sergeant Mars nodded thoughtfully:
"Well, that is to say, just a few days after we completed the inspection, this door was corroded by the poisonous mist behind the door... It seems that there are many undead on the underground floor."
He took out the key to the metal gate, inserted it into the keyhole, unlocked the lock, and then grabbed the door handle with both hands:
"Guys, get ready, I'm going to open the metal gate... Criminal Soldier No. 888, come here and help me open the door. Remember, after opening the door, you cannot retreat without my permission. No matter what happens You can only move on or stand still."
"Yes, sir."
Li Nuo held the door handle, his heart beating slightly faster.
He had a bad feeling that the scene behind the door might be a little unexpected.
The heavy metal gate was opened by the soldiers.
A soldier thrust a coal lamp into Li Nuo's hand.
Urged by the soldier's eyes, he stepped into the dark space without any light.
As soon as he stepped into the tomb passage on the underground level, the light of the coal lamp was further compressed.
Li Nuo fiddled with the light pick, then shook his head helplessly.
This damn place seems to be rejecting light.
Even if he turned the brightness of the coal lamp to the highest level, the light could only linger within a one-meter space around him.
Li Nuo could only move forward in near-dark conditions.
The cold air in the air became thicker, and the billowing cold air penetrated into the criminal soldier's uniform and traveled against Li Nuo's skin, causing him to shiver.
This is a kind of coldness that can penetrate the protective gear and body and directly affect the soul, as cold as it can take away all hope and vitality of the living.
Li Nuo gritted his teeth and walked forward bravely.
From the moment he stepped into the metal gate, his deconstruction skills never stopped.
He couldn't see clearly in the dark and could only rely on the feedback from the system to determine what he was passing by.
[System message: You are about to launch the deconstruction technique on the "ancient floor tiles"...]
[System message: You are about to launch the deconstruction technique on the "old wall lamp"...]
[System message: You are about to activate the deconstruction technique on the "Resurrecting Skeleton"..]
Wait, resurrected skeletons? ...Li Nuo stopped and listened.
A few meters ahead, there was very faint movement.
"Crack, click, click." It was like the sound made when fingers moved the ribs.
[System message: You are about to launch the deconstruction technique on the "undead creature with an unknown name"...]
An undead creature has appeared. Where is it?
Li Nuo opened his eyes wide, raised the coal lamp in his hand, and stretched his arms as straight as possible to let the light shine farther away.
Damn...what is this!
Li Nuo froze, his eyes dazed.
I saw a huge skeleton standing up slowly from the floor filled with bones.
The height of this skeleton is at least four meters, like a towering bone sculpture.
When it stood up, the white stone powder slipped from its body, revealing the surface of its bones covered with scars.
The light of the coal lamp shone on the skull's forehead, reflecting an extremely cold light, and Li Nuo shivered involuntarily.
In the skull of this skeleton, a purple light group lights up, as if to indicate that this undead creature is waking up from its slumber.
The brightness of the light group was much worse than that of a coal lamp. It seemed that it would take some time before this vicious creature would fully wake up.
However, Li Nuo could already feel the other party's gaze.
The huge skeleton was staring at him.
Li Nuo forced himself to calm down.
He looked back in the direction of the door.
Sergeant Mars and others were looking at the enemy solemnly and did not issue an order for Li Nuo to retreat.
One of them saw Li Nuo flinching and shouted:
"Stand still and don't move! That's a big skeleton, a low-level undead structure."
The short-barreled rifles in the hands of the soldiers seemed to be pointed at the undead creatures, and they seemed to be aimed at the backs of the criminals.
Seeing this picture, Li Nuo knew that his most difficult moment was coming.
It is the role of the reconnaissance team to find out the number and composition of the enemy.
To this end, the soldiers must use the biochemical baits on the criminal soldiers to awaken the undead creatures in the underground layer of the tomb as much as possible.
This large skeleton, which was over four meters tall, was just one of the first batch of undead creatures to resurrect, and it was far from the standard to figure out the enemy's strength.
They had to wait until more and more undead creatures resurrected before the soldiers could estimate the total number of enemy troops on the underground floor.
Only then will the guilty soldiers be allowed to retreat.
Instead of pinning their hopes on Sergeant Mars ordering a retreat in advance, it is better to rely on their own ability to reverse the predicament.
After Li Nuo thought quickly, he found two options.
First option:
Solve the problem of odor emission of biochemical baits.
As long as the biochemical bait does not emit a smell, the number of resurrected undead creatures will continue to decrease, and the chance of survival will increase.
But this will make the awakening of undead creatures less than expected, attracting scrutiny from soldiers. Sergeant Mars may also have a grudge.
Second option:
Find out the weaknesses and attack patterns of undead creatures and survive the opponent's offensive.
Li Nuo thinks this plan is better.
It is more subtle than the first option and will not attract unnecessary attention.
With a conclusion in mind, Li Nuo immediately said silently:
"Activate the deconstruction technique to deconstruct this undead creature and find out its weaknesses for me!"
[System message: You are about to launch the deconstruction technique on the "Big Skeleton". It is estimated that every 1 point of energy consumed can increase the completion of deconstruction by 25%. You currently have 10 energy points. Are you sure you want to deconstruct? 】
Most of the existing energy value is naturally restored during the passage of time.
As long as you pay about half of the inventory, you can get all the information about the big skeleton.
Li Nuo looked at the bright purple light in the big skull's eyes and no longer hesitated.
"Confirm that it will consume 4 points of energy to carry out a 100% complete deconstruction!"
