It's impossible to say not to be afraid.

No normal person will be calm when they know that they may have been infected with a deadly virus and face the possibility of mutation.

Maybe Cheng Jiayi and Du Yiyi are exceptions.

Li Li didn't know why he came up with such an idea again.

He habitually stretched out his hand, and suddenly he was stunned, and just when the alarm went off, the mobile phone was thrown on the desk in the office.

Li Li's expression changed, and he returned to the office in three steps and two steps.

His office was never locked — his phone lay quietly on his desk, with a black screen that never seemed to have been moved.

He looked around, picked up his phone, and swiped the screen.

The phone is still locked. He breathed a sigh of relief.

Enter the password, open it, and the screen of the mobile phone is still the picture in the villa, Cheng Jiayi is still with Du Yiyi, but Li Li doesn't want to hear what they say.

In the afternoon, he usually does not participate in outside patrols, and as long as there are no emergencies, he will stay in the police force.

He took a short break in his office to digest what had happened all morning.

There are only a few people in the research institute who can move freely, and there are dense surveillance cameras, so it is impossible not to leave clues.

A few minutes later, Li Li returned to the research institute.

The blood to be tested was temporarily closed because of the lunch break and the medical staff also needed to eat, and the test did not start until Li Li arrived.

The doctor who tested the laboratory was on the negative floor, and he had not been to the negative layer today.

An hour later, the test results showed that a male researcher named Marlin had an abnormal blood condition.

The second sample was taken, and the same doctor had a problem.

The rest is simple.

Dr. Marin was quickly restrained by the security guards on this floor and temporarily confined to a private room.

The case seemed to be solved easily. But it's hard for all to believe this fact.

How is it possible to calmly participate in a blood test after killing someone?

"I didn't kill anyone! I didn't trust the data from the blood test, I wasn't infected at all. Marin was still calm, he sat quietly in the room with the fence, saw Li Li, and demanded, "I ask for a new blood test, in front of my eyes." ”

The second time the blood test begins, this time, Marin asks for his own blood draw, and he doesn't trust anyone.

Li Li personally sent in a clean needle and saw Marin prick the needle into his vein. After taking the blood, he bent his arm and pressed the eye of the needle, and with his other hand, he moved the blood vessel up and down several times, and then handed it to Li Li's hand.

This time, the test results were normal!

He watched Marin draw blood with his own eyes, and handed the blood to the doctor for testing with his own hands, and the whole process did not escape his sight!

Li Li felt powerless.

He is not a professional criminal investigator, and he doesn't even know why he came to such a conclusion.

And to retrieve the surveillance video, Marin also has a video of a complete alibi.

As for human evidence, there is no way to investigate, and researchers spend most of their time doing experiments independently, especially analysis.

Everyone can be seen in other surveillance cameras during the crime.

In the surveillance video at the time of the crime, there are all the figures.

This is absolutely impossible. Unless the killer can clone or hack into the surveillance.

Could it be that some of these doctors and professors also know this and hack into the surveillance system.

Is it necessary? Sooner or later, this person will be found. Unless he can get out of here.

Li Li's heart was suddenly shocked. If this person can hack into the surveillance system, can he also open the access control?

But if he could open the curfew, why didn't he escape first, and he had to kill people first? Don't you know that it is more difficult to escape after killing?

Unless there is a last resort, be sure to stay there for another day.

What is the murderer going to do in the institute?

Li Yu retrieved all the surveillance videos of the institute within a week.

Viewing monitoring is very boring, especially when you need to compare before and after.

He almost confirmed that the video had been swapped, but was not sure from which time period.

The video of the swap must not only be the one outside the bathroom, the murderer must have an alibi, there must be another time to swap, and there must be a witness - does he really need a witness? Maybe he'll be gone soon.

Li Li looked at the video and felt at a loss for a while.

He stood up and looked at the institute behind him from his office window. The murderer needs to leave the gates of the institute, and also the gates of the squadron.

How did he leave?

Li Li thought of Professor Still again.

Will there be a part of the infected people who will not be tested out?

Before leaving work, Li Li stood in front of the professor again during his usual rounds.

"There's a problem. Still professor, do you believe that infected people will go undetected? For example, in your institute. Li Li observed his expression.

"Maybe." The professor was still expressionless.

"So, if you run away, what can you do so that you won't be discovered?" Li Li continued to ask.

The professor was still expressionless: "Theoretically, there is only one way, in exchange for blood for laboratory tests." ”

"There will be so many ordinary people's blood tested every day? Here, it is even more difficult to find the blood of ordinary people than it is to find the infected. Li Li stared into the eyes of the still professor.

"Maybe." The professor still has an evasive attitude, "I still have work to do, if Captain Li has nothing else to do, please do it." ”

When Li Li left, a sentry was arranged at the gate of the research institute. Although, the personnel within the institute can barely leave.

As a squadron leader, there is no off-duty time in such extraordinary times. The so-called off-duty time is just a specific time.

Li Li finished dinner and drove out in his car. Half an hour later, he returned to his villa. When they entered, Cheng Jiayi and Du Yiyi were having dinner.

"Captain Lee is back." All four stood up to say hello, and they all breathed a sigh of relief to see that there was no one else behind him.

Li Li carried two cardboard boxes, glanced at their dining table and said, "You guys eat first." These are for you. ”

Li Yu ran over with a cheer, opened the cardboard box, and cheered again: "There are vegetables, there are vegetables!" And fruits! ”

Cheng Jiayi and Du Yiyi also came over and opened another box. Only Wang Peng stood motionless.

"It's all fresh, and it's about the same effect as the dog meat you killed." Li Li looked at their happy appearance, and the emotions that had been suppressed for a day were somewhat relaxed.

"Great. Sister Cheng, let's wash a few cucumbers, one for each person. Li Yu asked Cheng Jiayi's opinion.

"Okay." Cheng Jiayi wants to go crazy when he thinks about vegetables. She has always liked to eat vegetables, but she has only eaten potato fungus and mushrooms in this week, and when she sees vegetables, she can't wait to eat them without washing.

Li Yu happily washed the cucumbers, and Cheng Jiayi and Du Yiyi put the contents of the carton in the refrigerator one by one.
