"Roar, it's finally here, let's have a gorgeous explosion!"

Seeing the information displayed on the beep boy, Dong Chen said happily.

But I was going to explore the science and technology department, but since I've come in, I'm not in a hurry, let's find a place to change my clothes and take a shower.

Dong Chen hurriedly found a room in the synthesizer recovery department, took a hot bath, and then used the radiation elimination device to remove the radiation for himself, rinsed it again, and threw the clothes into the automatic washing machine for radiation dissipation.

Since the pursuers of the synth recovery department often have to carry out activities in various places on the surface, it is the only place where you can find facilities to eliminate radiation, and the rest of the people here are all dead for 10,000 years, and they will not leave the academy for the rest of their lives, unless they do some related experiments, or they will not be infected with radiation for the rest of their lives, so they will not use radiation elimination devices at all.

After taking a shower, Dong Chen found an unopened lab coat to put on, and walked towards the competent department very easily, as for his clothes, they will be thrown away, and they will be automatically dried after washing, don't worry, he buys clothes very casually, they are all bought online, they are not worth anything, and it is not a pity to throw them away, his clothes were stained with so many dirty things before, he really didn't want it anymore.

The department in charge of the college does not engage in scientific research, but only carries out base management, maintenance and logistics matters, and needs to find the materials and thickness information of the outer protective wall of the college.

Dong Chen came to the competent department smoothly, and found a terminal here and began to consult the information, when he came here, he found that except for the original game about the plot and the location of the task The door was locked and did not let him in, everywhere else was he walked to the door, the door opened automatically, there was no identification card, and all places could go.

This is really a place where you have been staying for 10,000 years, and no outsiders will come in, for the sake of scientific research efficiency, you don't even need to verify the information, you can open the door wherever you go, tsk, it's really convenient for Dong Chen.

In the past, when he saw the automatic laser defense tower on the roof, Dong Chen would hide for a while, but later when he found that he didn't even care about the defense turret, except for some cautious people in the empty academy, Dong Chen had nothing to care about at all.

Dong Chen crackled on the keyboard, when studying artificial intelligence, Dong Chen had a deep understanding of the computer technology here, the typical feature is "gunpowder is used as fireworks", and I don't know if there has really been no leak here, the supervisor's passwords are simple and outrageous, Dong Chen originally planned to enter a few common passwords first, and then crack them, but he didn't expect to enter the 123456 for the first time, so he went in directly.

Alas, there is no place for heroes.

"Well, here, the construction time, hey, it's really early enough, it was built before the nuclear war, but also, the predecessor of the academy was the CIT of the Federal Institute of Technology on his head, which is the former underground laboratory, yes, it is written here, it was expanded after the war, and then the teleportation array was invented, and even the exit was blocked, and it was really planned to be a 10,000-year dead house."

"Found the structure and thickness of the outer protective layer, behind which it is ...... How much impact can the protective layer withstand when it is exposed, aha, isn't this what it was written for me! ”

"Well, take a look at the manual of the teleporter, here, oh, precautions, understand, let's go, set off fireworks."

Dong Chen stood in the teleportation room, listening to the countdown to finish counting, only to feel a flash of blue light in front of him, subconsciously closed his eyes, and instantly felt that his feet changed from a hard metal touch to a slightly soft earth touch, he opened his eyes violently, and found that he was already standing on the surface, and the long nose that had stopped running stopped five meters in front of him.

Dong Chen looked at his hands and feet, and twisted his waist again, it felt really magical, this was almost the same as his arc crossing gate, it was really amazing.

What's even more powerful is that I don't know how my arc gate came about, and the manufacturing process and technical reserves of this teleportation array can be found in the academy's database.

Dong Chen came to the side of the drilling machine and looked at the drilling depth displayed above, it was only twelve meters, which is really a bit shallow, but no matter how deep the underground building is, there must be a passage from the surface down, whether it is an elevator or a staircase, and think about the predecessor of the academy is just an underground laboratory, after the exit is removed, it is not bad that the highest floor can be twelve meters deep underground.

This is also thanks to the fact that he didn't rush to cut off this piece of land directly with the arc gate and throw it into the real world, if he threw it over, it would be a lot of fun, he doesn't know now, what will happen when the arc gate is closed when something crosses, there are other ways to do it, there is no need to take risks.

Went down a camera with lighting facilities, looked at the bottom and saw that it was indeed drilled to the outer protective layer, the extension rod of the drilling equipment was only ten centimeters in diameter, but the drill bit was forty centimeters in diameter, although a few drill bits could slowly drill through the protective layer, but even if it was drilled through, it was only a small opening of forty centimeters, and it was up and down, and it was impossible to go down at all.

So it's better to come to the explosives, and after blowing up a hundred, you can clear the soil layer on the top to form a big crater, so it will be much more convenient to go down.

Lifting the camera up, he then began to load the hole with explosives according to the plan calculated below, used a rope to put the last box of explosives in the plan, and then brought the remaining two boxes of explosives, and drove the engineering truck far away.

After Dong Chen hid, he took out the detonation device, the amount of these explosives and the combination of explosives with different attributes were calculated by him, which could not only blow up the protective layer, but also clean up the soil layer above, and not cause too much damage, because not far below was the teleportation array, or the only finished teleportation array, if it was blown up, although it could enter and exit through the gap, it was inevitable to feel distressed.

"Whew~~ It's time to witness the miracle." Dong Chen muttered to himself, and then pressed the button as soon as he could.

"Boom ——!!!"

Dong Chen saw that the soil on the ground was blasted into the sky like a flock of sparrows, black and pressed, and then immediately rushed around like a heavenly maiden scattering black flowers, and quickly fell down after the momentum was exhausted, because it was far enough away, he only felt the vibration of the ground, and when the shock wave blew over, he only felt that it was blown by a gust of wind, but those clods of soil had already rushed over, so frightened that he quickly hid under the car.

Listening to the sound of clods of earth mixed with bricks, stones, metal and other things falling, Dong Chen looked under the car to the place where the explosion occurred, where the dust had settled, everything had been blown up, forming a huge crater, because his position was not good, and the height was basically the same as the ground, he couldn't see the situation in the pit, but the surrounding buildings were miserable, the wall near the crater was basically collapsed by the shock wave, and bricks, stones, waste wood and paper were scattered all over the ground.

Tsk, this scene is really cool to watch, no wonder people like destruction so much.

When things stopped falling from the sky, Dong Chen came to the side of the crater to observe the effect, the maximum diameter of the entire crater is estimated to be ten meters, and the breach of the protective layer of the academy is estimated to be more than one meter, so the entire crater is in a cone, Dong Chen couldn't help but nod when he looked at this effect, it seems that the amount and mixing ratio he calculated were correct, and this explosion was completely similar to the result he estimated in advance.

Then there is something to do, to repair the entrance, but also to build a roof to prevent water leakage, but also to add a door to isolate the outside, there will be a radiation storm here, and then it is to absorb the knowledge of the academy, and then, you can go further and further on the road to open the black.
