The wasteland is reborn and the countryside is at hand

Looking at the scene in front of them, everyone paused for a moment.

Except for Li Yi and Bai Tong, everyone else thought that Li Yi killed the zombies that rushed in from outside the door.

There was a little blood on the back of the zombie's head, and it was hard to find the wound if you looked carefully.

"Too fast..." Jiang Zhe was the closest to them, but he didn't see how the zombies fell. He only sighed at how quickly Li Yi killed the zombies.

Li Yi looked at the admiring looks of others, and it seemed that there was no point in explaining. She was definitely responsible for killing the zombies.

"Let's go!" There was no point in talking. Li Yi was supported by Bai Tong and walked out of the classroom.

Perhaps there was too much noise just now, and there was a burst of noisy and chaotic footsteps coming from the stairwell at the end of the corridor.

But no one felt panic anymore. The zombie fell too fast. What would happen if a few more came?

There were not only four ordinary people among them. Qiao Yanjing was bitten by a zombie before because it happened too suddenly and there was no time to react.

Li Lanhong saw everyone leaving one by one, and she wanted to step forward to stop them, but remembering Li Yi's look that almost killed her, her legs could no longer stand up.

Deng Yunlong walked at the end. When he left, he wanted to dig out the crystal core from the head of the zombie who had just been killed. After a few seconds, he stood up with a solemn face, looking thoughtful, but he still did not forget to turn around and dig out the crystal core. The classroom door was closed tightly. This was the only kindness he had towards Li Lanhong.

For a moment, only Li Lanhong was left kneeling on the ground in the huge classroom. She was crying, but she didn't dare to make a sound. She was the only one left here. If zombies were attracted, no one could help her. Despair filled Li Lanhong's heart, and being left behind by the team was her own consequences.

The experimental building has only four floors and is U-shaped as a whole. There is no elevator and only three staircases. Two narrow staircases are located on both sides of the floor. The widest staircase is in the middle of the floor.

The stairwells on both sides were blocked by security doors. I don't know who locked them, but there were roars of zombies inside.

The staircase in the middle was open. Li Yi and the others walked up the stairs, but they didn't see a single zombie in the empty corridor.

"This place may have been cleaned up. Most of the zombies were led to the stairwell and locked up. The zombies encountered before may have been missed."

Li Yi's voice was not loud, and she was slightly panting when she spoke. The battle with the two black cutters consumed so much of her energy that she had to rely on Bai Tong's support to even walk with ease.

Qiao Yuze looked around in surprise. Indeed, as Li Yi said, there was no trace of zombies in the empty corridors.

"How did you do it by locking all the zombies in the stairwell?" he sighed.

Facing the threat of zombies, human potential is unlimited, including force and wisdom.

Li Yi's expression became serious, and she reminded: "There are other people in the building, please be careful."

Everyone became vigilant after hearing this. Past experiences told them that in the last days, they had to be wary not only of zombies and mutated monsters, but also of similar people with vicious hearts.

This is an experimental building. Li Yi's goal is not just a safe place to breathe, but the experimental equipment here.

She is a researcher, and these cold instruments may be just scrap metal in the hands of others, and can only be used as containers at most. But for Li Yi, these instruments may be able to change the fate of her and her companions, and even the fate of mankind. destiny!

They checked every floor, and the house numbers clearly marked the purpose of each classroom.

In addition to the security room, weak current room, clean room and teacher's office on the first floor, there are also two tea rooms and toilets on each floor.

The second floor has multi-functional halls and exhibition halls, conference rooms, research studios, etc. Half of the entire floor is a non-experimental area, while the other half is a laboratory.

The third floor is all laboratories.

The fourth floor is bounded by stairs, and on the west side are more professional and dedicated laboratories, with a total of eight rooms.

Room 401 is a biosafety level laboratory located on the west side of the fourth floor. It contains viral factors for research by teachers and students. In laboratories such as universities, it is generally within Level [-].

The "BSL-1" on the door plate of this laboratory clearly indicates that it is a Level [-] biosafety laboratory, which is the most basic laboratory and is used for basic teaching and research.The first-level viral agents used in the study are very harmful to living individuals and do not have the ability to cause disease to healthy adults, animals and plants.

The higher the level of biosafety laboratory, the more dangerous it is.

Personnel conducting research in Level [-] biosafety laboratories must receive special training in disease source handling before entering. Level [-] viral agents are microorganisms with moderate potential harm to people and the environment.

Level [-] biosafety laboratories are even more dangerous. The viral factors used in research can cause people to be infected with serious or even fatal diseases through the respiratory route of pathogenic microorganisms or their toxins.Viruses tested under this safety standard can cause severe, potentially fatal illness if inhaled through exposure.

As for the Level [-] biosafety laboratory, it is called an "aircraft carrier" in the field of virus research, and very few people can get involved, or dare to get involved.The viral factors are highly dangerous to the human body, and the transmission route of the virus is unknown. There are no vaccines or treatments for the pathogenic microorganisms or toxins.

Although the zombie virus is scary, its mode of transmission is obvious. Although there is no cure, if you really want to study it in a laboratory, a secondary laboratory is enough.

But where is the need for a laboratory now?It would be nice to be able to research in peace.

Li Yi thought that she only had one gene serum left in her body. In order to prevent accidents like today from happening again, she would immediately make Jiang Zhe and Nie Shiwen immune to the zombie virus.

As for whether they can become evolutionaries, it can only depend on the luck of two people.

402 is a radiation laboratory, which conducts research on radionuclides and is generally used for research on the marine environment and climate. Only then did Li Yi realize that they had left Pengcheng City and hit Anhai Province by mistake.

There are four cities in Anhai Province that are close to the sea. The closest to Pengcheng City is Longshui City.

Because of the panic, Li Yi and others ignored the plaque outside the school gate. Now that I think about it, this should be 'Longshui University of Science and Technology'.

Even without yaw, the distance between Longshui and Xijing City is more than 20 kilometers shorter than that of Pengcheng.After understanding the geographical location, Li Yi finally felt confident.

403 is the radioactive isotope room, which is probably a laboratory whose main research object is isotopes, and the research object is radioactive.

404 is a static magnetic field laboratory for anti-vibration, anti-radiation, and anti-electromagnetic interference. As the name suggests, if Qiao Yuze is put in for research, I don't know if there will be any results.

The house numbers of 405 and 406 both say clean room, which is used for some sterile experiments.

Both 407 and 408 are constant temperature and constant humidity laboratories, and some experiments have stricter requirements on temperature and humidity.
