Xue Xiaodong and Zhang Hao and Hua Zhengnan formed a team after they met, and the team of five people had a clear division of labor, Hua Zhengnan and Zhang Hao went to find the key to the school bus and the gate, Liu Jin and Chu Linhai guarded the stairs just in case, Xue Xiaodong's bag still had a vacant place, and went to get the medicine and fresh water that could be taken away

Fortunately, there are more fresh water reserves in the laboratory building, and boxes of mineral water are piled up under the table, in order to ensure that the speed of movement is not affected, Xue Xiaodong loaded three bottles and did not take any more, as for medicines, he also picked some often used to take them, such as cold medicine and antipyretics, etc., and also brought a few boxes of digestive medicines just in case

Hua Zhengnan was covered by Zhang Hao, and he easily got the key to the school gate, but the school bus key could not be found, and the key was usually placed on the driver's body, but at this time there was no driver in sight

"Brother Zhang, you cover me, things are not quite right"

Hua Zhengnan suddenly realized that there was something wrong, and hurriedly summoned others to hold together, there are four floors in the experimental building, and now several people are on the third floor of relative safety, and the second floor has been searched again, confirming that there are no zombies and living people, so only the fourth floor is left

Hua Zhengnan recalled the past, the driver recruited by the school has always not left his post, after all, the school has food and accommodation, as long as he does not need to drive the school bus, he will definitely stay in the residence on the third floor, everyone is familiar with each other on weekdays, but now he can't see the driver, even if he leaves, it is impossible to bring nothing, his house looks very clean, there is no sign of leaving at all, and the door downstairs is also closed, according to Xue Xiaodong's memory, the door is closed before the three of them enter, Then the bus driver and others are likely on the fourth floor or on the rooftop

"Don't be separated, don't shout, hear no, we have to get the car keys"

Although the five people are fully capable of opening the main gate of the school now, but after opening the door, a few people have no chance to escape, if there is no vehicle, it is easy to be besieged by a group of zombies, not to mention five people, fifty people may not survive tonight

As the five people slowly entered the fourth floor, a pungent smell of blood came over, and they couldn't feel it at all on the third floor just now, but as soon as a few people entered the fourth floor, they felt that the problem here was not too serious

Zhang Hao, Xue Xiaodong, and Liu Jin stood at the front, Chu Linhai and Hua Zhengnan protected the back, and the five of them protected each other and walked up the stairs on the fourth floor

Chu Linhai felt a little scared, so he suggested that everyone might as well not go into the fourth floor and make some noise at the staircase on the third floor, if there were really zombies on the fourth floor, they would definitely come down, but they were still vetoed by everyone, because they didn't know how far the sound would go, and the number of zombies on the fourth floor, if there were too many, the five people couldn't cope with it at all

"These guys are walking very slowly, don't be afraid"

Zhang Hao tried his best to comfort everyone, according to what he heard on the walkie-talkie before, the bones of all the infected people were attacked by the virus, especially the leg bones, so they walked very slowly

But at the moment when Zhang Hao finished speaking, his face was like being beaten, and he only saw a thin figure walking out, this is a director of this medical school, and he rarely interacts with people, but the teaching level is still good, Hua Zhengnan recognized it at a glance, but compared to his unchanged appearance, his shoulder with one less piece of flesh is the most shocking

"Attention, he's infected, everyone work together and attack his head"

Looking at the five people who were sent to the door in front of them, the infected director was not polite, and ran directly over with one step on both legs, the five people may have seen the infected person who can run for the first time, and they were all frightened, especially Zhang Hao and Liu Jin, the two of them saw the infected person going in their direction, and they waved the weapon in their hands at the same time, hitting the head and waist with a stick, and directly knocked the infected person out

Looking at the zombies that were shot away by the two of them, Liu Jin's sweat was finally able to take the time to wipe it, just now he suddenly rushed over and really scared him, and at the same time he also said with some panic, "Didn't you say that this thing can't run, why did it run all of a sudden?"

Faced with Liu Jin's question, Zhang Hao didn't know how to explain it, so he had to admit that this guy was more special after being infected

"Ahhh

By the time Chu Linhai raised the mop stick, the infected person had already jumped in mid-air, giving Chu Linhai an excellent opportunity

When the five people got closer, they found that this infected person was different from other people, and it was only a day since the outbreak of the virus, and the infected person's body began to fester, and his belly was bulging, and it was obvious that he had eaten a lot of live animals recently

Without waiting for the infected to get up again, the attack rained down frantically on the infected's head, which was the end of his suffering

Hua Zhengnan recalled the scene he saw with Zheng Lao in the hospital, the infected person who was originally walking very slowly also began to run soon after being injected with the vaccine, and before others could react, he ran past the laboratory on the second floor with a shovel, and when others followed, he saw him slumped next to the microscope

Zhang Hao didn't know how to use medicine, and his biology was not very good, so he couldn't see anything at all, but the other three were all medical students, no matter how bad their grades were, they could enter this school before, and they were by no means as simple as ordinary good students

Chu Linhai and Liu Jin looked at everything under the microscope, and they also felt as weak as Hua Zhengnan, as for Xue Xiaodong, he was relatively calm, judging from the situation under the microscope, this virus will continue to split, that is to say, if a zombie eats a lot of food, it will have enough nutrients to nourish the virus, and the virus will become more powerful after reaching a certain number, so that the host will begin to mutate, and the kind that can run just now should only be the most ordinary mutation, and after that, there are likely to be more powerful mutant infectees
