“Talk less, so you can inhale less.”

Mondox didn't care about that, he ran straight into the depths of the ruins.

Su Mo and the others immediately followed.

Compared to the fierce fighting outside, the entire ruin was eerily quiet, making people feel uneasy.

Su Mo was vigilant about his surroundings, avoiding being attacked by surviving monsters. He was now a little nostalgic for the Fake Creator Devourer.

If that guy was around, he wouldn't have to be so nervous. At least it would watch out for him.

Before long, they arrived at the sinkhole area.

Longke took a look at the bottomless sinkhole and couldn't help but swallow.

“Are you sure we're going to climb down with our bare hands?”

“That's right, it should be fine. So many prisoners controlled exoskeletons to go down before, drilling out a lot of holes in the uneven metal walls. If we're careful, it shouldn't be a problem.”

Without saying a word, Mondox took the lead and began to climb down.

“Follow him.”

Tilly was the first to follow. Since Mondox was confident that he could climb down, she had nothing to fear.

Su Mo, Kendi, and Yan Gang also followed without saying a word.

Only Longke was left with a trace of fear on his face, but he finally gritted his teeth and followed.

Su Mo carefully climbed down.

The metal walls of the entire sinkhole were uneven, with many protruding steel bars that could be used as handholds.

As the climbing depth increased, the gray mist in the air became thicker and thicker, with visibility of only two or three meters.

Moreover, the air smelled more and more unpleasant, and it was very uncomfortable to inhale into the body.

However, Su Mo still endured it, concentrating and not daring to be distracted. If he wasn't careful, he might really fall.

If he fell into the biochemical pool surrounding the platform below...

He would probably turn into a puddle of water. No matter what kind of gene potion he had injected, it wouldn't work.

More than an hour later.

Su Mo and the others gradually approached the bottom and could already vaguely see the outline of the platform.

At this moment, Mondox turned his body sideways, kicked the wall hard, and jumped towards the platform.

“So fierce, and there's still at least seventy or eighty meters to go.”

Longke's eyelids twitched violently.

“He did the right thing, we have to jump, otherwise we won't be able to get over the annular biochemical pool later.”

Su Mo's pupils shrank, and without saying a word, he jumped down. In mid-air, Su Mo curled up his body.

Then Su Mo landed on the ground and rolled around, maximizing the impact force.

Tina and Kendi jumped down one after another and landed very smoothly.

Only Longke looked at this height and kept backing down in his heart.

At this time, Yan Gang next to him grabbed Longke's hand and threw him out, then jumped down.

“Help!”

Longke couldn't help shouting.

Su Mo stretched out his hand and accurately caught Longke.

“I'm finally saved, thank you, big brother.”

Longke said gratefully to Su Mo.

“Stop talking nonsense and hurry up and follow.”

Su Mo put Longke down and chased after Mondox.

At this time, Mondox had already walked towards the central staircase passage without stopping.

After entering the underground laboratory area.

Everyone looked around. There wasn't much difference here from before. The only difference was that the emergency lights in the corners of each passage were on. The prison soldiers who came down to clean up the ruins before should have repaired the emergency lighting system here.

“Which way do we go?”

Tilly asked.

“Just follow me.”

Mondox immediately turned right and entered an inconspicuous narrow passage.

Then they went around and around, turning everywhere.

Su Mo frowned slightly. Ange had shown him a map of the entire laboratory area before.

If he remembered correctly, Mondox was now leading them to the corner, which seemed to be a dead end.

Could it be that Mondox held something back when he handed in the map?

“Big brother, what's wrong?”

Longke keenly noticed the subtle change in Su Mo's expression, so he approached and asked in a low voice.

“It's nothing.”

Su Mo didn't say much. He planned to take it one step at a time and see where Mondox was going to take them.

In order to prevent being ambushed, Su Mo deliberately quickened his pace and stayed a little closer to this guy, so that he could react immediately if anything happened.

Half an hour later, Mondox led Su Mo and the others to the end of a corridor. A dirty metal wall came into view. This was a dead end.

“Are you sure this is the place?”

Tilly frowned slightly and asked. It didn't look like there was a ship here.

“That's right.”

Mondox raised his hand and groped on the wall.

Su Mo and the others watched quietly, but there was no reaction for a long time.

“How about I do it? I'm better at this.”

Longke grinned and volunteered.

“Okay.”

Mondox then stepped back and gave the position to Longke.

Longke immediately stepped forward, raised his hand and kept tapping the metal wall lightly. He pricked up his ears and listened carefully.

At this time, Mondox, who had stepped back, leaned on the metal wall on the right side. He suddenly exerted force on his body and retreated backward. Immediately, the metal wall behind him turned like a rotating metal door, and Mondox retreated directly into it.

“Not good!”

Su Mo and Tilly felt something was wrong at the first time and rushed in at the same time.

However, upon entering the room, it was pitch black, without a trace of light. At first glance, they couldn't see anything at all.

However, this didn't stump Su Mo and Tilly. Relying on subtle sounds, the two blindly chased in the same direction.

Longke and the other three then realized that something was wrong and rushed in at the first time.

At this moment, all the lights in the entire area suddenly turned on. Su Mo and Tilly immediately stopped and their bodies stiffened.

A V generation biological mecha, Zhen Yu Shi Zhe (Hell Warden), stood up, a hundred meters tall, with a red metal Tyrannosaurus head, covered with red scaly armor, huge in size, holding a scarlet giant axe, a hundred-meter-long metal tail behind it, embedded with six pairs of mechanical wings, embedded with nine special suppression steel pipes behind it, and exuding violent power all over its body.

Its scarlet eyes stared at Su Mo and Tilly.

Su Mo and Tilly retreated back at the same time. They were kidding, they didn't even have a set of exoskeleton armor.

What could they use to fight the V generation biological mecha?

“It's over, it's over!”

Longke said tremblingly.

Mondox raised the scarlet giant axe in his hand and pointed it at Su Mo and the others.

Su Mo and the others didn't dare to move at all, or they would surely die!

---------------

Underground central control.

Artificial intelligence, Prisoner, floated in mid-air.

Holographic images floated around it.

And the holographic image in front of it that it was monitoring was none other than Warden Fizek.

It made a distorted mechanical synthesized voice and said.

“Stupid fellow, do you really think that if you cut off the power lines, I won't be able to control the prison? I am God, and God is omnipotent. Slowly die in despair.”
