Soon, Ren Xiaosu ran against the flow of people to the back of the crowd, at this time, there were three experimental subjects chasing thousands of people behind the crowd to kill as much as they wanted, when they found that Ren Xiaosu rushed towards them, one of the experimental subjects actually gave up the target they were attacking and pounced towards Ren Xiaosu!

But before they could rush in front of Ren Xiaosu, Ren Xiaosu had already drawn his knife out of the void, and at this moment, Ren Xiaosu's figure didn't even pause, but suddenly accelerated, and his whole body rubbed past the experimental subject who pounced.

The sharp black knife handle was held by Ren Xiaosu's backhand, and he could feel the subject's body slashing across the blade, and the gray skin was "unraveled" by the blade.

The muscle fibers in the gray skin were broken one by one.

Immediately after that, the bone is cut out of a smooth fracture.

Eventually, the gray body was split in two, spraying a large amount of pale yellow blood!

At this time, the crowd that fled to the gate was blocked by the test subjects intercepted in front of them, and the crowd subconsciously wanted to run back, not that they could survive by running back, but they didn't know what to do!

The people who were in distress had lost their minds at this moment, they had not been trained to evacuate, and they had not faced the wilderness, so the desire to survive could not guide them to find a way out.

The moment they turned around, they saw the subject being dismembered.

The black knife, a teenager full of power and bursting, the ferocious test subject seems to be vulnerable under the blade.

A girl was suddenly surprised to find that the boy was not Ren Xiaosu, who had been asked to drop out of school in their class?

At that time, they were afraid that Ren Xiaosu, a homeless person, would bring illness and death to everyone, but what did the students who defended Ren Xiaosu say at that time.

On that day, one of Jiang Wu's students said to them and their parents: "Help, we are not helping him, and he doesn't need our help, you don't know anything about the world outside the barrier, I think it's a sadness." ”

At the time, no one else knew what the student was talking about, but now, she thought she probably understood.

It turned out that this world was already so dangerous, and those students who fled from the wilderness to the 109 barrier had clearly experienced danger with Ren Xiaosu, so they knew very well what kind of ability Ren Xiaosu had.

This ability may not be of much use in the barrier, but the barrier is too small compared to the world.

The girl grabbed a middle-aged woman beside her and shouted, "Mom, it's Ren Xiaosu!

The girl's mother suddenly looked complicated, but at this life-and-death juncture, how could she have time to think about anything else: "Do you know him, call him back to save us!"

At this time, the fleeing crowd who were forced back by the experimental subject saw that Ren Xiaosu was able to kill the experimental subject, so someone immediately shouted: "Follow him, follow him!"

They felt as if they had found a savior, thinking that they would survive by following Ren Xiaosu.

However, after Ren Xiaosu killed one of the test subjects, he did not stay at all, but accelerated out of the battlefield again, so as not to delay his time when the remaining two test subjects came together.

His goal now is to save people, not to stay here and kill test subjects!

In just a moment, Ren Xiaosu had already left the experimental subject and those fleeing crowds far behind.

Seeing that it was impossible for the subject to catch up with Ren Xiaosu, the test subject looked back at the frightened refugees, the girl watched Ren Xiaosu run farther and farther, she just wanted to open her mouth and call Ren Xiaosu to come back to save them, but the test subject in front of her had already pounced again and bit her throat!

The girl's cry for help could no longer be called, and there was only despair and emptiness in her eyes.

Ren Xiaosu has never been a savior, and now in this whole barrier, he only cares about the life and death of one person.

At this time, the palace suddenly said: "Mission: to save the inhabitants of the fortress." ”

But even so, it didn't make Ren Xiaosu turn back.

The task must be completed, but Yang Xiaojin is also a barrier resident, can he complete the task if he saves Yang Xiaojian?

For the tasks released by the palace, Ren Xiaosu can always have his own unique understanding.

Just as he was running for his life, Ren Xiaosu was suddenly surprised to see an experimental subject squatting next to an unconscious man, who had no injuries on his body, and seemed to have just been knocked unconscious.

Ren Xiaosu avoided the experimental subject, but he couldn't help but look at the other party's strange behavior.

Normally, the subject would have pounced on him when he saw a living person, but this subject seemed to have something more important to do.

Seeing that the test subject suddenly opened his blood basin and spit out his tongue, Ren Xiaosu thought that the test subject was going to lick it before eating, but he was stunned to find that the end of the tongue was actually rolled with a small syringe.

The next moment, the subject took the syringe in his hand, and then pushed the gray liquid in the syringe into the veins of the man's neck!

There was a cold current behind Ren Xiaosu that suddenly rolled upward, what is this experimental subject doing?!

Luo Lan had mentioned it to Ren Xiaosu before, saying that these experimental subjects were doing experiments, and at that time, Ren Xiaosu was still thinking about what the experimental subjects would do without experiments, but at this moment he was shocked.

The man with a normal complexion, his skin suddenly turned gray at a speed visible to the naked eye, and his muscles, which were not particularly strong, began to bulge rapidly!

In the past, Xiao Su thought that the goal of the test subject was to kill all the surviving targets, but now he found that the other party did not kill everyone.

What is the liquid injected into the man's body?

To be honest, when Luo Lan mentioned things like 'nanorobots' and 'experimental subjects doing experiments' before, Ren Xiaosu was still a little disdainful, after all, civilizations have been broken these years, and science and technology must still be in the initial stage of revival.

But Ren Xiaosu suddenly remembered that Zhang Jinglin had said that there was no real fault in science and technology.

Zhang Jinglin's exact words were: "They are only in the hands of a few. ”

This is probably the reason why a consortium was able to become a consortium.

Now, Ren Xiaosu probably understands why there are more and more experimental subjects.

It's no wonder that the subjects are once again attacking the human barriers, as they must occupy new barriers and gain fresh blood if they want to get food and expand their population.

If the 113 Walls hadn't collapsed due to the earthquake, they probably wouldn't have been able to grow so quickly, because they couldn't have breached a single barrier at the time.

But after they expanded their group at 113 barriers, they already had enough power to devour a barrier.

Ren Xiaosu knew that he had no time, and he had to leave here with Yang Xiaojin as soon as possible.
