Professor Still stayed in the institute, part of the most important reason was to cure the infection.

But now not only is Professor Still, but Li Li himself knows that this kind of infection cannot be cured. Apart from death, otherwise, with the existing technology of human beings, they cannot take out the crystals in their heads safely.

Then, the next purpose is to understand the crystal and understand yourself.

Li Li didn't have much contact with Professor Yiran, but judging from his understanding of Professor Yiran, even if Professor Yiran improves his "mutation intensity", at least at present, he will not do anti-social behavior.

Not even in the future.

Some people are not born to be able to perform antisocial behavior.

Li Li closed the video and looked at the second piece on the paper.

This one is very confusing to remember.

Cheng Jiayi and Du Yiyi want to obtain legal status through him - how is it possible? How can they think that he, a WJ squadron leader, can get safe blood test results?

Take a step back and say, even if it is done, why would he give them a green light and let them do whatever they want?

Just because he still leaves them in his villa?

But why did I keep them there? I really don’t have any other ideas?

Li Li became irritable again.

The harsh sirens suddenly sounded, and Li Li jumped up suddenly.

"School alert, first-level alert. Institute alert, first-level alert." Standard sounds appeared on the radio.

It’s not that Professor Yi Ran is sick. Li Li rushed into the dispatch room.

"What's the situation?" he shouted.

"The body of a doctor was found on the first floor of the negative floor, and all the doors of the entire institute were closed with caution." The dispatcher said quickly.

"Tick me the monitoring room inside." Li Li picked up the microphone.

"Captain Li." A picture came from the screen, which was a picture of the cleaner running out of the bathroom in panic. "We have closed all the passages and someone has rushed over."

Li Li nodded, "I'll go there now."

A doctor died in the institute. Li Li's first reaction was to kill someone and silence him.

The alarm will be cancelled soon.

Li Li stood at the crime scene of the institute.

This is the bathroom on the negative floor and is one of the few places in the entire institute where there is no monitoring.

The body was found in the bathroom compartment.

During the second cleaning of the day, the cleaner found that the compartment was closed and could see someone inside from the bottom of the door, and the position of the standing was not so natural.

After knocking on the door without sound, I felt something was wrong. I looked up from the next door and found that the person inside was dead - leaning against the wall.

As soon as the monitoring room saw the cleaning staff rushing out, it panicked and immediately sounded the alarm and closed all accessible sections.

The one who died was a researcher on the negative floor and did research with everyone in the morning.

Fortunately, there were videos in addition to the bathroom. After a preliminary examination on site, the bathroom was closed and the body was carried into a research room.

The most deficient thing in the institute is doctors. If you solve the problem of the cause of death, you don’t need professional forensic doctors.

The alerts from other layers were quickly lifted, and only the negative layer was still continuing.

Li Li came to the surveillance room, and all the surveillance that the researcher appeared on that day had been found.

He arranged work normally in the morning. At 10:30 in the morning, he left the laboratory to go to the bathroom, and never came out after entering.

Next was the video outside the bathroom. Half an hour before the researcher entered, all the shots of those who had entered the bathroom were tuned out.

The camera shows that when the dead researcher entered the bathroom, there was no one in the bathroom. Then, no one went in for at least half an hour.

Researchers will not be killed after entering the bathroom for half an hour, nor will they squat on the squat for half an hour in one breath, even if their stomachs are damaged.

Moreover, the researcher's clothes are neat and not convenient at all.

The cause of the researcher's death is simple: suffocation.

As soon as he entered the bathroom, he was knocked unconscious by a stick, and then a rope strangled his neck.

There are no traces of struggle at the scene and clothing.

Any doctor will know where to hit it and will faint or lose the ability to resist.

Don't expect to leave fingerprints.

All doctors wear medical gloves all the time.

But who can lurk in the bathroom for half an hour or even more?

There was already a lack of manpower, and now we have to arrange for people to investigate and record videos.

The second layer of negative was soon restored to research.

The dead researcher was diagnosed with blood tests and confirmed that he was not infected.

For a moment, everyone's eyes at the people around him changed when they looked at him.

A person who was not infected died, and died here must be because he knew something.

What do you know? What else should be kept secret in the institute? What are you afraid of people know? There is nothing else except being infected.

Everyone who came to the first floor of the negative layer that day had to take blood tests again.

Li Li knew that everyone's physical strength was now greater than their original self, and the infected mutant had strong explosive power. Even if it was a female mutant, it would be very easy to kill an ordinary person.

What he was curious about was how an infected person could have the confidence to escape the test.

Everyone was drawn by a nurse who had just tested and confirmed that he had not been infected. Li Li stood aside and stared at all the people who came to the test.

Although Li Li is not from a criminal investigation, he has received similar training and knows that many people who have just done the case cannot stand the police's aura and will reveal flaws in front of the police. His aura has always been very strong.

Of course, there are also ordinary people who have never made any mistakes that cannot stand this kind of sight.

Some people were frightened, some were very nervous, some were afraid, and there was almost nothing they didn't care about, including Professor Yiran, who also frowned.

Everyone left two blood samples and then tested and compared them separately.

Although the murder occurred, work still had to continue and lunch also had to continue. Li Li had already noticed the hunger in his abdomen. And the irritability appeared again.

The murders in the institute are controlled within a few people's understanding. After all, researchers working in the institute, including cleaning, food and accommodation are also included.

After Li Li finished lunch, he felt a little more irritable.

But there are still.

Li Li felt something was wrong.

This feeling of frequent irritability only occurred the day before, to be precise, it only occurred in the middle of the night the day before, after meeting Cheng Jiayi and the others.

He carefully recalled all the process after that, and made sure that he had not been infected with the blood of the infected person, whether in his mouth or on his skin.

Logically speaking, he is an infected person and will not have obvious symptoms of illness due to contact with people with infection and mutated conditions. Is he going to get sick again?

What I have seen these days and his own experiences have made him know that there are definitely many infected people lurking among ordinary people. I can't tell when these infected people will suddenly mutate.

Could it be that his irritability is a sign?
