He and his sister were only separated by one seat. For this reason, Ma Tao also tested the two positions back and forth. The result was true. The detector did not respond when it was in the passenger seat, but it responded when it was in the driving position of his sister. , it’s really quite a magical thing.
"Could it be that...the place where things are buried is just so different?"
Ma Tao held the metal detector in his hand and muttered to himself doubtfully.
"I'll know if I drive a little further."
As her sister said, she started the chariot again and moved in the direction shown by the detector. As expected, the detector showed more accurately.
Ma Tao understood at once that things were exactly as he thought. He was only one and a half meters away from the position displayed by the detector. In other words, the thing was in his hand and the detector could detect it. the maximum position edge.
"Sister Xiao Jinzihan, follow my car."
After understanding this, Ma Tao's face was filled with excitement and he immediately called others to follow his car.
The maximum radius of the metal detector is only thirty meters. This distance has been detected by Ma Tao again and again, so the location displayed by the metal detector is actually not far from their location. Soon, they will arrive The place detected by the detector.
"Brother Tao, are you sure this is here?"
Xiao Jinzi from Jeep No. 2 sounded indescribably excited.
"confirmed"
Ma Tao, the co-pilot, nodded, and then said, "Old rules, sister, you and Gao Han stay in the car, and the others get out and dig."
The three underground floors are full of dangers, and you may encounter any situation, especially the laser earthworm. If you are really hit by the laser of that thing, you will lose at least half your life, and digging is still a very long job, which takes time. Therefore, the three tanks surrounded the position displayed by the detector to form a safe triangular area. Once the middle was free, they could dig as much as they wanted.
Although the triangular tank defense can effectively block sudden attacks, this formation is destined to only passive defense. There is no good way in the current environment. At this time, we can only choose to give up some armor pieces.
As soon as the three tanks formed a triangular area, Ma Tao took the pot and climbed out of the tank. However, due to the design of the tanks and tanks, he was still not as fast as Xiao Jinzi to get out of the tank. This guy was already lying on the ground and started digging sand there. .
Su Lanyu also got off the chariot. Ma Tao deliberately left Gao Han behind and did not mention her because Ma Tao felt guilty for this cold and charming woman. He did not arrange any work for her and did not expect her to participate in the battle. However, Su Lanyu It's really good that people also lend a helping hand when they need her help, including when she offered to cut vines to clear the way at the entrance of the cave before and during the two excavations in the sand, she took the initiative to help without saying a word. Ma Tao is very pleased. It is a reason for others not to help, but it is friendship to help you. After all, Su Lanyu does not owe Ma Tao anything. He even indirectly saved Ma Tao's life when he was in Shura Hall.
The soft sand was easy to dig, but none of them thought that the thing buried underground was not very deep this time. It was less than half a meter and three people touched a metal object, and the thing was not small. .
This discovery made Xiao Jinzi so happy. He thought he had found a chariot, but when he expanded along the edge, he discovered that this thing was not a chariot, because it was a cube, about one and a half meters long and wide. Jin Zi was still a little disappointed at first, but soon the boy's face was filled with an unstoppable smile.
"Is it the engine?"
When he was halfway through the digging, Ma Tao could see what was buried in the soil, but the engine in front of him was quite special. It was even said to be the first time Ma Tao saw a unique engine in this world, because The appearance is really special enough.
The engine in front of me is wrapped in a transparent waterproof film. After tearing off this waterproof film, the engine is inside.
"It's V24, my God, this is actually V24..."
After the engine was completely dug out of the sand, Xiao Jinzi knelt in front of the engine with an entranced look on his face. His eyes were in disbelief and his trembling fingers touched the metal shell of the engine. His expression was like He is as fascinated as touching the woman he loves most.
"Isn't this just an engine? As for..."
Ma Tao looked at Su Lanyu who was about to pick up the sword and leave after digging the sand, and then asked Xiao Jinzi.
"Brother Tao, this is a V-series engine. You have to know that if an engine enters the V-series, it is the threshold for being listed as a top-level engine."
As for Ma Tao's incomprehension, Xiao Jinzi couldn't explain much, but he still caressed the engine he called V24 with a silly smile on his face.
In fact, it's Ma Tao who doesn't know much about engines. The V series engine is a model that has been around for a long time, but there is Xiao Jinzi nearby. With this guy, he can explain everything to you clearly as long as it has to do with tanks. Chu.
Ma Tao learned from Xiao Jinzi that V refers to an arrangement of the engine. All the cylinders of the engine are arranged side by side in a plane at the same angle. The cylinders are arranged in a straight line. We call such an engine an in-line engine. In-line engines Features: Its advantages are that the cylinder block and crankshaft structure are very simple, and it uses one cylinder head, with low manufacturing cost, compact size, high in-line engine stability, good low-speed torque characteristics and less fuel consumption; but the disadvantage is that The length increases greatly as the number of cylinders increases.
Talking about V-type engine
Divide all the cylinders into two groups, and arrange the adjacent cylinders together at a certain angle so that the two groups of cylinders form a plane with an angle. The cylinders are V-shaped when viewed from the side, so it is called a V-type engine. Because the V-type engine has two sets of cylinders, the number of cylinders is an even number. The height and length of the V-type engine are small, which makes it easier to arrange in the car and leaves more space for the cockpit. The cylinders of the V-type engine are arranged in opposite directions, which can also offset part of the vibration and make the engine run more smoothly. The disadvantage of the V-type engine is that it must use two cylinder heads, which has a complicated structure and high cost. In addition, after its width is increased, the space on both sides of the engine is smaller, making it difficult to arrange other devices.
There is another engine that is an upgraded version of the V-type engine, which is the W-type engine.
The principle of the W-type engine is to stagger the cylinders on each side of the V-type engine at a small angle. To put it simply, the cylinder arrangement of the W-type engine is composed of two small V shapes forming a large W shape. Strictly speaking, W Type engine should also be a variant of V-type engine.
Features of the W engine: The W-type engine is shorter than the V-type engine, which helps save space and is lighter in weight. The disadvantage is that its width is larger, making the engine room fuller. To be precise, it exceeds the V24 engine. It can be called a W engine, or it can continue to be called a V.
Engines in the world no longer use fuel. They all use nuclear energy. The continuous nuclear fusion will generate a large amount of heat energy to drive the engine. In fact, the principle is similar to that of fuel, but now the operation of tanks is more precise. Environmentally friendly, no exhaust, and truly zero pollution.
After listening to Xiao Jinzi's explanation, Ma Tao roughly understood it, and even more clearly understood how excellent the engine in front of him was.
"Are you going to hold it forever?"
Suddenly, his sister's voice came from beside him. Ma Tao turned around in surprise and found that it was really her sister.
"Lan Yu is here to help with the security. I'll help you get this thing to the car."
My sister knew the reason why Ma Tao looked at her and quickly explained.
“Good time”
Ma Tao didn't say anything. The weight of this engine is not light. It is indeed difficult for Ma Tao and Xiao Jinzi to get into the car. However, it will be different once the sister joins. The sister is also a robot, and the human body cannot compare with it in terms of strength. of.
Lifting up the engine, my sister's feet had sunk deeply into the sand, but fortunately, it was just an engine after all. My sister still put it on the jeep safely, and Xiao Jinzi did it himself. This newly unearthed V24 was installed. As for the original BUL engine, naturally it could not be thrown away. It was all paid for. The money did not come from the strong wind, so I had to trouble Sister R to put it in the back of the jeep. .
The armor pieces consumed by the laser earthworms finally revealed an advantage, that is, Xiao Jinzi's jeep can still drive normally even with such an additional engine. This is absolutely impossible if it is fully armored and must be disassembled and assembled. Throw away the armor, but after Xiao Jinzi replaced the V24, all this became no longer a problem.
It was Ma Tao's decision to put this V24 engine on Xiao Jinzi's Jeep. Now this guy has the least amount of armor. It would be impossible if he didn't increase the power output of this guy's engine quickly. As Xiao Jinzi completed the replacement of the V24, The result did not disappoint Ma Tao.
After being tested and identified by the C device, Jeep No. 2, which originally could only carry more than 700 armor pieces, can now carry more than 1,940. His vehicle's budget for carrying armor pieces suddenly became the largest. This one also made Ma Tao realize the horror of this V24 engine.
Although the current armor plate number of Jeep No. 2 can be increased to more than 1,900, there is no place to add additional armor plates to this guy. The reality is still the same as before.
While Xiao Jinzi was changing the engine below, Ma Tao had been sitting in the driving position of the tank to guard him. Sister R was left by Xiao Jinzi's side by Ma Tao. At this moment, Sister R was opening up the energy shield to be on guard at any time. These are the two preparations Ma Tao made for a sudden attack from anywhere. They were responsible for guarding in the car. Although this can maximize the counterattack against the enemy, after all, only Xiao Jinzi can be left outside, alone. A person is more likely to be attacked by monsters. So Ma Tao thought of asking his sister to protect her first. Relying on the defensive power of her sister's energy shield, he believed that it would be no problem to block the first wave of attacks. As long as the first wave of attacks was blocked, then the rest would be no problem.
While waiting for Xiao Jinzi to install the engine, Ma Tao had been thinking about a question. From the time they found the 105 cannon to the C device to this good V24 engine, Ma Tao always felt a little strange. These are all must-haves for the tank. The indispensable equipment is now scattered in various places as if it has been dismembered. It seems as if someone is deliberately not wanting to be found. When Ma Tao found Nick, the C device, This idea came to mind, and now it is even more urgent. Maybe the tank is really in this cave. However, Ma Tao did not mention this idea to anyone. He had not found the tank yet. At the time this was all just a hypothesis.
As soon as the V24 engine of the second car was installed and Xiao Jinzi successfully started it and confirmed that there were no problems, Ma Tao asked his sister to drive the chariot while he ran to the co-pilot's seat and used a detector to detect this three-story underground engine. The space is not small, and the possibility of having other things is not impossible, but the probability is not very high. Even if you hide things by yourself, you will not put everything in one place. This is like not putting your eggs in one basket. It's a truth. After all, if someone really finds the treasure, he will think of searching around and trying his luck. Ma Tao does this just because he doesn't want to let go of any corner here and wants to continue searching. Just rest assured that you won’t regret it.
The result was indeed like this. After searching around, nothing was detected, and we also encountered two groups of monsters, wasting some armor pieces in vain.
After confirming that it was safe to come out of the third underground floor on the slope, Xiao Jinzi's jeep only had more than 330 pieces of armor left, which could be said to have reached a critical point.
"Continue?"
On the second floor, after careful consideration, Ma Tao once again solicited everyone's opinions. Although he was the captain of this team, he could not lead everyone to death.
At this moment, the ammunition consumption of the three tanks is really not much. The number of rounds in the three tanks is more than 30, but the number of armor pieces is already appalling. None of the three tanks has more than 500 armor pieces. , the one with the most is still Gao Han’s No. 3 CMB ambulance, which has 490 armor, followed by Ma Tao’s No. 1 car, which has 410 armor, and the least is Xiao Jinzi’s No. 2 car, which has 320 armor. , it is precisely because of this that Ma Tao wants to seek everyone's opinions, because the next battle already represents an escalating danger. If he does not leave, the remaining road will really be a tough battle. Don't be afraid of anything else. If all All you encounter are laser earthworms, which will be troublesome.
"I think we should retreat"
After Ma Tao asked for a long time, no one said anything, and Gao Han hesitated for a long time before speaking.
"I think we should continue. The tank can fight for a long time even without armor pieces."
Xiao Jinzi had just obtained the V24, and when he was extremely energetic, he certainly didn’t want to give up halfway. After all, no one could tell whether he would be able to come back once he left. After Xiao Jinzi saw it, they were likely to be far away from the rumored vehicle. The chariot is not far away, and it would be a pity to give up at this time.
"I also think we can continue to explore for a while, but it would be a pity to leave like this if we don't try our best."
Su Lanyu's proposal came from the watch. Surprisingly, this woman actually agreed with Xiao Jinzi's proposal.
In fact, if you think about it in another way, it is normal for Su Lanyu to say this. She is a character who likes excitement and prefers games. Otherwise, she would not have chosen to put all her bets on Yan. In the end, they lost both the wife and the army. Now in this situation, everyone has a vague premonition in their hearts, that is, they are not far from the truth. It was this feeling that made Su Lanyu express her own opinion.
Ma Tao didn't speak. Sitting in the passenger seat, he closed his eyes and meditated. He couldn't feel the vague treasure-like mood in this, but he was afraid. He was afraid that his decision would affect everyone. People are led into the bottomless abyss, but it is too late to regret it. This feeling is like the call of Medusa. Is what is waiting for you a great opportunity or an irreversible snake and scorpion evil spirit? This is It depends on how you make your choice.
"In fact, we can just focus on escaping. Even if we are attacked, we will ignore it and just rush over."
Xiao Jinzi said another method that he thought was feasible but was quickly rejected by Ma Tao.
"no"
Ma Tao rejected his argument with just two words, and then continued using his communication watch, "It doesn't matter if monsters like acid ants or missile frogs attack us. The point is laser earthworms. The power of these things The damage is too high”
Almost all the other monsters in this cave do not do much damage to the chariot. Only the laser earthworm is the most fragile monster. It can even be killed with an old-fashioned gunpowder gun, but its destructive power is really It's so big that if there were no laser earthworms, Ma Tao and the others could definitely walk sideways here.
"It would be great if there was a way to solve the problem of laser earthworms."
Su Lanyu said something in the watch.
"It's impossible. Since that person chose to hide these things here, he must have chosen this place because he knew how entangled the laser earthworms were."
Gao Han's words were like a plate of cold water that instantly doused everyone's thoughts, but what Sister Han said was also true.
"I also have four grenades and three ice bombs in my special magazine. These group-damage shells are very useful against such fragile monsters and can deal with several laser earthworm crises."
Ma Tao listened for a long time, he didn't want to give up halfway, but there was no comprehensive way to retreat, and he had to find the chariot with his life.
"You can also use smoke to confuse the sight of earthworms."
Gao Han thought for a while, then added, but her voice still sounded a little worried in the watch.
"There is another way, that is to have a vehicle cover each battle, and the laser earthworms can withstand all the blows and let others attack. Once there is damage, I can repair it, so that we can extend the possible distance we can travel. Stretched further”
Xiao Jinzi thought about it for a long time and came up with an idea, and said excitedly to Ma Tao in his watch.
"This is a way"
Ma Tao went over the method proposed by this kid in his mind, and finally felt that it should be feasible.
"Then let's try it first. Once all our tanks lose their armor, we must return immediately."
The minority obeyed the majority, and Xiao Jinzi, Ma Tao and Su Lanyu all agreed to move on. Gao Han also reluctantly agreed, but she reserved her opinion, but what should be reminded must be said, and Gao Han must insist on this.
"I think so too. Once all our tanks lose their armor pieces, we must return."
Gao Han's proposal was also what Ma Tao wanted to say, and their opinions coincided here.
Returning to the entrance from the second floor to the first floor, Ma Tao began to turn around and explore deeper into the second floor to the south.
This time the cave was much narrower and a little more crowded than the places we had walked through before, but that was fine, it was safe.
The direction showed that the cave was a curve. Their route was first to the west, and then to the north in an area of puddles. During this period, they encountered three laser earthworms and a mine turtle. Taking advantage of the discovery they had just made, the horse Tao used a special artillery shell and grenade to take away the lives of the three laser earthworms with one shot. The remaining mine turtle was also sent to the sky by Xiao Jinzi. Because it was discovered in time, there was no chance of encountering the enemy this time. The armor pieces were lost and more than 500 G were gained.
Good luck seemed to be tilting in their favor. After encountering the three laser earthworms and a thunder crow, they continued northward along the cave to the end and then began to travel eastward for a long distance without encountering anything. Monster, finally, the three chariots finally arrived at the end of the cave, but looking at the entrance of another underground cave that could extend to three levels underground, everyone was as big as their heads.
But since we were all here, there was no reason not to go down. So I decided to take the lead and got off first.
When they reached the third floor, Ma Tao felt dizzy again. The third floor here was not that big, but in front of them there was another hole that could lead to the lower floor. This was obviously a fourth floor. existence.
Just like taking the stairs, after going down one level, there is another level. On the way to the fourth floor, he also encountered a wave of mine turtles. In order not to waste time, Ma Tao still chose to use a special artillery shell and a grenade. All these yellow-shelled tortoises were taken away.
On the fourth underground floor, it has become quite dry because it is very deep, and the temperature has also risen a bit. There is a pungent smell of sulfur in the air, and the ground is no longer just like the fine sand above. There are many more volcanic rocks, and the walls on both sides are also the kind of solidified rocks that have been precipitated by magma. It seems that this place should be an extinct volcano. Through the searchlight light, Ma Tao can still vaguely see those on the ground that were once covered by the flow of magma. The traces of time and the passage of time seem to have stayed permanently with the solidified magma.
