An Na explained to Guo Zhenyu why there were so many huge monsters. Only now did Guo Zhenyu know that this group of irresponsible alien people, in order to conduct business, had gone out of their way to capture animals on Earth for genetic modification and sent them to the Federation to be sold as pets or weapons.

Later on, when people discovered this dirty business and the defendant went to a federal court, they had no choice but to leave Earth. However, these modified animals were left here to fend for themselves.

"Then what should we do now?"

Guo Zhenyu looked at the two toads in the water and felt a headache coming on. He had already tried it before, even though he took out a pistol from his space bag, but before he could pull the trigger, the two fellows had already hid themselves in the water. It seemed like they understood that although the thing in that creature's hand was scary, if he hid in the water, he would not be able to kill himself.

Guo Zhenyu had no way to deal with these two cunning toads. All he could do was fly in the air and confront these two fellows hiding in the water.

"Do you have any ideas?"

Guo Zhenyu had no choice but to turn to An Na for help.

"You just need to keep an eye on the experimental monsters. Although these guys look cunning, in reality, the experimental monsters are giving them instructions."

An Na said to Guo Zhenyu.

"However, other than the fact that I instructed the Coffin Beast to attack me previously, I did not hear any other movements."

Guo Zhenyu was puzzled.

"That's because you can't hear him. He's using infrasound to talk to these guys in the water."

An Na said to Guo Zhenyu.

Hearing this, Guo Zhenyu felt his head hurt, feeling that he had been played around by someone. He did not even know what had happened, it seemed that his IQ was lower than a wild man's!

After An Na told Guo Zhenyu about this situation, she told herself to "listen".

The infrasound that arrived was also transmitted to Guo Zhenyu. After Guo Zhenyu heard the sounds, he suddenly discovered a completely different world. Previously, he had thought that this cave was very quiet, but now, he could hear many complicated sounds.

"An Na, I have always had a question."

An Na originally thought that Guo Zhenyu had something to say, but she realised that this guy did not ask her about the answer that she had already guessed.

"Tell me, what do you want to know?"

Although An Na was surprised, she still answered Guo Zhenyu's question.

"If these remodeled fellows are so powerful, then why are they still refusing to leave this place?"

Guo Zhenyu asked his own question.

"Very simple."

An Na replied, "Although these guys have been modified, they are not. Initially, in order to conveniently manage the goods and to not let them wander around, those fellows had done some work on the goods, making it impossible for them to leave this dark and humid place. Once they leave this place, the temperature would change.

An Na replied.

"In other words, these guys are restrained, right?"

Guo Zhenyu seemed to be planning something as he continuously threw questions at An Na.

"..." Yes, as soon as the temperature changes, they will die. The temperature that humans can accept, for these guys, is like putting them in an oven, do you understand now? "

An Na said a lot of things, but Guo Zhenyu only remembered this one sentence.

"System, search through the surrounding underground water for me."

Guo Zhenyu suddenly jumped back to the system.

"Finished searching. The map has been sent to the host's mind."

The System replied weakly.

Indeed!

Guo Zhenyu's guess was right. There was indeed an underground hot spring nearby, and it was not far from here.

Guo Zhenyu thought for a while and directly exchanged for a disposable digging mouse. He let the machine drill into the hot spring while he stood in the air facing the three amphibians.

Not far away, the wild man was still hiding in the dark and giving orders to the three of them. He hadn't gone far yet.

After Guo Zhenyu heard the sound, he walked towards that guy. It caused him to lose a set of high-quality armor, so how could Guo Zhenyu let it go? He immediately flew towards that guy with the tranquilizer gun in one hand and the blade in the other.

In the darkness, the experimental body heard the sound of flapping wings. It hurriedly ran outside, but how could it outrun Guo Zhenyu?

Guo Zhenyu followed, first throwing out a blade and cutting off half of the experimental subject's leg, then shooting out several more sedatives before he managed to subdue the big guy.

"Didn't I tell you to relax and not hurt him?"

An Na was furious at Guo Zhenyu's actions and shouted loudly.

"Isn't he still alive?"

Guo Zhenyu muttered in dissatisfaction.

An Na knew that Guo Zhenyu did it on purpose, but he did not say anything. He controlled Guo Zhenyu's hand and stabbed it into the heart of the experimental body.

After Guo Zhenyu's hand had entered the heart of the experimental body, Guo Zhenyu only felt an itch on his fingertip, as if something was about to escape.

This feeling lasted for several minutes. After a long while, that feeling finally disappeared. As the itchy feeling disappeared, the heaviness in Guo Zhenyu's heart also disappeared.

Only now did Guo Zhenyu confirm that An Na had already taken out the gene that was planted in her body.

Not long after, that savage's eyes suddenly snapped open, scaring Guo Zhenyu to the point that he almost made up for it with another stab of his blade.

After that savage woke up, he stood up and smiled at Guo Zhenyu, "Okay, from now on, we don't owe each other anything. If I catch you again in the future, you will be my next body."

Only that crazy An Na would say those words.

As An Na walked, the wild man's original appearance was also slowly changing.

His original height of three meters changed to the size of a normal person. Then, the red hair on his body slowly fell off and turned into a normal human body.

An Na possessed the experimental body, causing the three monsters to lose control and slip into the water. However, they heard the sound of the drill, and were attracted by the sound.

"Boom!"

At the end of the drill, after discovering the entrance of the hot spring, he detonated himself. Instantly, the hot spring flowed through the one meter wide tunnel.

As Guo Zhenyu had expected, the three huge fellows were scalded by the hot spring and scrambled towards the shore.

The two toads were still alright as they climbed up to the shore. The only pitiful thing was that newt, both its legs were broken by Guo Zhenyu and it was scalded to death in the water.

As for the two toads that had landed on the shore, Guo Zhenyu made a 'thump thump' sound.

A few shuttles were broken into pieces.

After he had finally taken care of all these fellows, Guo Zhenyu immediately ran towards the place where An Na had disappeared to. Based on the actions of the experimental body just now, the exit must be there.
