"You'll know when you get out. You'll definitely be surprised!" Wang Lei's voice was full of confidence.

This small passage is not long and you can walk out after walking a few dozen meters.

Then, everything became clear to me, and everything in front of me became much brighter.

"this……"

Xu Xin opened his eyes wide and looked at the scene in front of him in surprise.

He really didn't expect that after coming out of the control room, he would see such a scene!

In front of me is a very wide space.

Compared to the dark dungeon, this place is bright and spacious, at least two hundred meters in range.

and……

He lowered his head and looked down.

This space is not only wide, but also deep.

It is at least fifty or sixty meters deep.

He looked behind him and to the sides again.

Behind him was the prison he had just walked out of...

From his current position, he could roughly see that this was actually a metal cylinder with a diameter of nearly 100 meters!

A cylindrical building located underground!

And now, he is on the top floor of this cylindrical building!

Moreover, it is equivalent to standing on the balcony and overlooking the scenery here!

This scenery was indeed something he had not expected.

Unexpectedly, the scene outside this underground prison was like this.

The outer perimeter of the cylindrical prison is a circular space that is fifty to sixty meters high and at least two hundred meters wide.

The entire cylindrical metal underground prison with a diameter of 100 meters stands in the middle of this space!

The entire space should have hollowed out the underground within 200 meters around the underground prison.

Xu Xin raised his head and looked upwards.

He was now very close to the ground, only three meters away.

The ground of the underworld was now directly above his head.

However, what was above his head was not soil, nor stone, but...

A whole piece of metal!

The metal replaced the entire ground above this area, covering the entire space.

Moreover, this piece of metal was emitting a white light, which was similar to the white light emitted by the gap in the air outside, thousands of meters above.

Because the distance was very close, the white light was a little dazzling.

Xu Xin suddenly realized!

No wonder!

No wonder Coco suddenly stopped him when he was about two hundred meters away from the vine bundle.

Coco must have noticed that there was something unusual on the ground!

Because, although the ground around the vine bundle looks to be covered with a layer of pale red contaminated soil, underneath the contaminated soil, it is actually all made of metal!

The underground surrounding this entire bundle of vines is a huge trap!

If you miss a step, you will fall directly into this place!

And Wang Lei's words also confirmed his guess.

"I missed a step and fell, then fell into a coma. When I woke up, I was right here." Wang Lei pointed to the ground below and said, "I must have fallen directly here. The ground below seems to be made of some special material, which is relatively soft. Even if I fall, I won't get hurt."

"So that's how it is..."

At this point, Xu Xin already understood the structure of this underground prison.

The underground in this area has been hollowed out.

In this hollowed-out area, there is a cylindrical prison in the center and traps on the outside.

When creatures from the outside world fall into this trap, they will fall into a coma due to some unknown factors and fall onto the soft ground outside.

At this time, the "staff" in the prison will transfer the unconscious creatures in this area to the cylindrical prison in the center by moving or operating the precision instruments in the control room.

When they woke up, they were already imprisoned.

This is indeed the experience of Zhao Xiaochuan and Wen Guixin.

There were some minor incidents when Wen Guixin was being moved.

but……

Why wasn't Wang Lei imprisoned? Could it be that...

"Brother Xin, we can walk around this big steel pillar and see everything underneath this space." Wang Lei said to Xu Xin.

Their current position is equivalent to the balcony on the top floor of a cylindrical high-rise building. This balcony surrounds the building, so naturally they can walk around it and see what is below.

This "balcony"-like facility should be the place where the "manager" of this area observes what creatures are caught in the trap below.

What about the prison administrators?

How come I haven’t seen any of them in such a long time?

It can’t really be…

"Ying!" Coco had already circled around by itself, and at this time, its voice came from the other side.

"Haha, it seems Coco has discovered it!" Wang Lei laughed.

"What did you find? The body of the hairy monster?" Xu Xin looked at him and asked.

"Ah? Can you guess this?" Wang Lei was stunned.

Xu Xin walked around quickly.

There were several corpses of hairy monsters lying on the ground in a disorderly manner.

"Hmm!" Coco's voice came from the front again. Xu Xin looked up and saw several corpses over there.

And the death of each corpse here...

They were exactly the same as the hairy monsters they had just seen in that room.

They all looked extremely withered and their faces were purple, obviously they had been poisoned.

"These hairy monsters were also killed by Sister Gui Xin's poison. You can tell from the way they died." Wang Lei kicked the corpse on the ground and said.

Xu Xin looked at the corpses speechlessly.

He finally understood the current situation.
