With a crisp sound, Lu Shan fell with a punch, already smashing the glass wall that divided his body to pieces, and his body finally escaped and regained his freedom.

But at this moment, there was a loud "bang" not far away, and then the whole building was shaking violently, as if it might collapse at any time.

Then Lu Shan saw all the various instruments and display cabinets in the surrounding laboratories smashed on the ground. Even some glass walls burst open due to violent vibration and compression.

I'm going... These guys are really cruel! This is so... Is it going to self-destruct the entire camp?

Lu Shan let out a sigh of relief, and wondered to himself that after such an explosion, he didn't know if the elevator shaft had been completely destroyed?

If the shaft is completely destroyed, Lu Shan really doesn't know how to enter the underground laboratory!

By the way... this explosion is too cruel! It is estimated that even the underground laboratory must be greatly affected by this, and it may collapse directly.

If this exit is blocked, the people inside will not be able to get out... Lu Shan doesn’t believe it. Such a secret laboratory is tens of meters underground. It must be a safety issue. If there is only one exit, once someone is blocked, isn't it a dead end?

But... the laboratory is underground after all, and it has withstood such a terrifying explosion. Once it collapses... then there is really nothing left!

But soon Lu Shan realized...the people in the camp should not be so stupid! Don't look at the explosion that started in the elevator underground, but it seemed like a directional blast. The horrible fireball mainly erupted all the way upwards. As for the explosion below the elevator, it didn't look much fierce.

So, it's really hard to say what the underground laboratory looks like now!

Lu Shan waited for a while, and found that the shaking of the building had completely stopped, but occasionally there was a sound of bottles and cans being smashed, so he immediately turned around and jumped directly from the window to the first floor again.

Once again found the location where he had opened a big hole before, Lu Shan found that the shaft inside was still there, and it had not collapsed due to the explosion, but at this moment, there were bursts of smoke and heat wrapped in it. Keep pouring out.

Lu Shan waited for a while, until the smoke inside was almost dispersed, and then went back into the hole...

The oil wire rope hanging above the elevator is gone, and the metal frame around the shaft has become dilapidated, but it doesn’t matter... For Lu Shan, he doesn’t necessarily need these things to assist him, just sticking to the wall all the way. Decline, he will not have any problems.

After putting his hands on the wall in the shaft, Lu Shan found that... the wall was so hot at the moment.

This is him. If you dare to put your hand on it when you are an ordinary person, you will be burnt instantly.

Although Lu Shan felt that the wall was very hot, he would not have much reaction, but... even if his climbing skills are already very advanced, he still feels a little strenuous to absorb his body on the wall!

This is because... after the high temperature burning of the big fireball just now, the walls around this shaft have been glazed and become abnormally smooth, the kind that mosquitoes have to slip when they fall on it.

Fortunately, Lu Shan didn't want to climb up, but to descend...So you don't have to worry about that much, as long as you can strain your hands to prevent him from falling straight down.

When he stepped on something under his feet again, he found that he was stepping on some broken bricks. It seemed that the explosion still caused the upper part of the elevator shaft to collapse. But... Lu Shan kicked the broken bricks around with his foot, and he quickly cleared a gap, seeing a slight light coming out from the front.

The elevator car was naturally completely blown up, and the original position of the car was covered by the broken bricks, earth and rocks falling from above!

However, the ruins were not too big. He took a few more vigorous strokes along the direction of the light, and quickly saw the situation outside.

It looked like a small hall outside, but half of the ceiling was collapsed, making it a mess.

At this moment, no one is guarding outside. It is estimated that those who ambush Lu Shan originally thought that Lu Shan was bound to die!

After all, this explosion is so ingeniously designed, and the power of the explosion is so amazing. If someone was in the elevator car at that time, it would definitely be exploded without leaving any bones.

Since I feel that the invader is dead, and here is the source of the explosion, even the ceiling of the small hall outside has collapsed halfway, no matter if anyone was hit just now, the rest of them will definitely not dare to stay here again. Up!

Lu Shan opened the gap a little more, then squeezed out with a bowed body.

Looking around, he saw a small door on the left, so he walked carefully behind the door over there and listened.

Behind the door, some people walking and even talking could be heard faintly, but the distance was relatively long. From this it can be seen that... there should be no more ambushers here.

Lu Shan immediately flashed through the small door, and then saw a long staircase behind the door...The staircase stretched down, and the light was on above the passage, so you could see far away... but even if Lu Shan saw Go, at least you can see two or three hundred steps, but you still can't see the end of the steps!

He smacked his tongue secretly, and then went all the way down the steps without hesitation. Unexpectedly... At his speed, this step actually walked for more than a minute, during which time it turned two turns, and finally... when he walked out of a door at the end of the step, in front of him It is a brightly lit underground world!

Yes... This can be called the underground world, not the mysterious underground laboratory he had imagined before!

Just now through the steps that went all the way down, Lu Shan estimated that he should have gone down more than a hundred meters.

This also means... this underground world is nearly two hundred meters deep underground.

Obviously, it was transformed from a natural cave underground. Although there are traces of artificial repair on the surrounding rock walls, the more it goes up, the more natural it is.

The height of this natural cave is probably more than fifty meters, and the area... from Lushan's side, it can be at least five or six square kilometers, or even larger, which is impossible to calculate accurately!

This area is much larger than that of the barracks above, so...no one can imagine that under that seemingly ordinary barracks, there is such a huge underground base.
