Since then, she has never killed anyone anymore, and she has just crushed the other party's knees in the parking lot.

But Qingchen is different from her. Qingchen was a hunter that night and was actively searching for prey.

She recalled the bloody footprints on the ground that night, and then the boy's persistence and coldness in chasing the murderer in the dark.

The most intuitive impression of Yangyang is: this young man is very dangerous.

When he went downstairs, Nan Gengchen murmured beside Qingchen, "Brother Chen, I saw the sketch of the transfer student. Did she discover your identity? Was she present at that time? Why haven't I seen her before?"

Qingchen glanced at him: "I have the chance to talk about this."

"Oh," Nan Gengchen nodded: "Brother Chen, can you give me the sketch? I'll go back and frame it for you to commemorate it. Speaking of which, the girl's painter is really good. When I saw the sketch, I remembered what happened that night."

Qingchen said helplessly: "Do you want to offer me some incense?"

"Ahem, I don't mean that," said Nan Gengchen: "Brother Chen, I think that girl looks pretty. Did she sit next to you with something interesting to you? You two..."

As a result, Qingchen turned his head and looked at the deskmate seriously: "It is not a good habit to joke about girls behind the scenes."

"I know, I know," Nan Gengchen admitted his mistake with hunch: "But Brother Chen, is it really okay for you to be collected? I'm sorry, I'm dragging you down."

"There is no burden or not," Qingchen recalled what happened that night: "It was to save you at first, but it was not."

"What's that?"

"Because, some things have to be done."

On the playground, more than ten white tents had been set up at some point.

Qingchen looked over and suddenly found that the little eagle who had hit a car in the courtyard of No. 4, Administrative Office Road was also wearing a white coat and a white mask...

On the playground, the most conspicuous person is not these white tents, but Liu Dezhu.

More than 30 rich second-generations were around him, and everyone looked at the classmates on the playground with a laugh, looking fresh as if they had come to the countryside.

Not far away, Yangyang silently watched everyone line up for a physical examination. Qingchen and Nan Gengchen stood in the team, extremely calm.

She saw it.

When it was Qingchen's turn to collect blood, the boy sat in front of the table without hesitation, stretching out his arms, as if he was not worried at all.

"Is this young man already injected with genetic agents to change his DNA, so he is so confident?" Yangyang thought to himself: "I thought he might be Li Shutong's student, but now it seems that I was wrong?"

No one noticed it.

When Qingchen drew blood and left, the little eagle in a white coat came into the white tent.

The nurse who was responsible for collecting blood for Qingchen silently handed over a blood test tube. The figures of the two interlaced for a moment, and the blood test tube had been moved into Xiaoying's hands.

He looked around as if nothing had happened, and then quietly got into a 120 ambulance.

He took off his white coat from the car, looked at Zheng Yuandong beside him and said, "Boss, I got it."

Zheng Yuandong nodded and said, "Go to the forensic identification center, I need to know the result as soon as possible."

Xiaoying thought for a while and asked, "Boss, do we need to be so cautious? I understand that you arranged large-scale blood collection. This is to prevent students and parents from panicing. But taking his blood samples alone also requires so cautious and concealing?"

Zheng Yuandong glanced at Xiaoying and explained calmly: "There are too many people looking for him. Although we need to confirm his identity, we must also ensure his safety."

"Is there anyone looking for him? Is Kyushu?" Xiaoying was curious.

Zheng Yuandong shook his head: "It's not just Jiuzhou, I'm afraid there are more than we imagined."

...

...

At 5 pm.

In an office in the forensic identification center, Xiaoying came to Zheng Yuandong with a test report. He hesitated and said, "Boss, it's not him."

Zheng Yuandong rarely had a solemn expression on his face. He took the test report and confirmed it repeatedly, and finally confirmed that the young man named Qingchen had his DNA that was indeed incompatible with what they collected.

He looked at all the clues he had obtained.

In the quiet office, Zheng Yuandong closed his eyes silently.

He followed the footsteps of the boy in his memories, approaching the truth as if he was peeling off his cocoon.

However, all the clue chains that are related to each other like spider webs are completely broken because of an inspection report.

It seemed like someone had to cut it off.

"Boss?" Xiaoying couldn't help asking, "What should I do now?"

Zheng Yuandong stood up and said, "Maybe it's not him, but the killer on Laojun Mountain must be him. I believe in my judgment."

Zheng Yuandong was thinking.

If all his clues are correct, the test report proves that his speculation is wrong.

Then there must be a clue in between that he didn't know yet, which led to the test report pointing to a wrong conclusion.

"He changed his DNA," Zheng Yuandong said to Xiaoying.

Just between the Laojun Mountain incident and the blood collection incident, in this timeline of more than 20 days in the world, Qingchen changed his DNA!

This is the most reasonable explanation.

The young man must also know that the blood sample left by the other party in Laojun Mountain is a very fatal clue, so the other party took the initiative to change his DNA in the past twenty days.

But what means can change one's own DNA? It's only genetic medicine.

But the question is: "If he was another time traveler in Prison No. 18, a student of Shutong Li, and the person behind the scenes covered by Liu Dezhu, how could he choose to inject genetic medicine?"

You should know that everyone in the world knows very well that genetic medicine has sequelae.

In the New Civilization Era, the earliest genetic agents came from the Taboo Inquisition.

They imposed the extracted "god" gene fragments on human genes through the potion.

Later, the gene agents gradually increased, and various consortiums seemed to have found the genes of new humans from the forbidden places and then extracted them.

But the sequelae also follow: those who inject genetic medicine cannot have children.

This is like a very simple truth. Any gain will inevitably be lost.

Everything has a price.

So, will Li Shutong's students bear such a serious price to hide their identity? Of course not.

In order to survive, family status, protect relatives, and make a living, the people at the bottom are very important to consider genetic medicine.

Because in an era when human life is as paper, only when they become useful and valuable can they live a little better!

But the upper class never bothered with genetic medicine!

Thinking of this, Zheng Yuandong suddenly looked at Xiaoying: "Do you... blame me for injecting you with genetic medicine?"

Xiaoying scratched her head and smiled, "Boss, everyone chose what you said, and they all know the sequelae."

"But you may be too young to realize how serious this matter is. Even if you don't mind, your wife will."

Xiaoying smiled and said, "I'm so happy that I can't find my wife."

Under Zheng Yuandong's gaze.

Xiaoying hurriedly said, "Boss, I'm joking. And... there are always some things that need to be done by someone, right? Don't worry, we have all sworn without regrets."

...

...

The office suddenly became quiet, and Zheng Yuandong was silent.

Xiaoying asked when she changed the question: "Boss, will there be someone behind Qingchen?"

Zheng Yuandong pondered: "I have thought about this possibility too, and it seems that this possibility is only left. The person behind the scenes has always been very cautious, and there is no reason to rush to the front of the stage from behind."

Just like He Jinqiu, few people have seen him take action so far because the other party wants to be the one who is good at planning and controlling everything.

From this point of view, Qingchen and Liu Dezhu are both like chess pieces in the hands of someone, and are placed in front of the stage to play.

The night in Laojun Mountain, the killer was so bloody, and it didn’t look like something a person hidden behind the scenes should do.

"I need to confirm it again."

After saying that, Zheng Yuandong dialed out a phone call and said, "Help me heilai Nan Gengchen and Qingchen's chat history, all of which have been passed down since the time travel."

I don’t know who the call was called, but soon the chat history was sent.

Zheng Yuandong looked carefully, but found that for a long time after the incident began, Nan Gengchen did not know Qingchen's identity as the Time Walker.

Until the last return.

He looked at the chat history:

"Brother Chen, are you here? Are you here?"

"Brother Chen, listen to my explanation!"

"No, Brother Chen, Li Yinuo and I are ordinary friends!"

Zheng Yuandong felt strange: "Hey, they suddenly encountered it in the inner world, and something strange happened, which caused Nan Gengchen to be anxious to explain. Li Yinuo, I have heard of this name. Isn't this the name of the third eldest daughter of Li's family? I also saw news some time ago that she led the Qiushou team to the wilderness..."
