"Hahaha, I'm sorry Zhao, it's really a habit to develop during this time!" The person who came was Zhao Yu's target, Dr. Osman, and the emaciated middle-aged man with glasses said with a smile: "I really didn't expect it to be you, I thought it was the army coming to the rescue!" ”

Zhao Yu rolled his eyes, who are you, the army will come to save you, and people are busy saving themselves: "Doctor, except for me, no one will come to save you!" The outside world is turned upside down! ”

"That's bad news, do you have anything to eat? I can't stand it anymore. Osman said, clutching his stomach.

"Yes, outside, let's go, I'll take you out!" Zhao Yu happily approached Osman and wanted to take him out, so far the main challenge has been completed! But he still has to protect him until the antidote is invented, because there is a sentence to save mankind at the end of the main line challenge, Zhao Yu is afraid that the system will be boring, if the antidote is not invented, is it a failure of the main line? And the punishment challenge, Sophia's recovery also needs an antidote, and Osman will be his most important object of protection next.

"Wait, I've got to stay here!" Osman rejected Zhao Yu's enthusiasm: "I'm studying these zombies now, I just have some clues, and I can't leave!" ”

“。。” Zhao Yu was speechless, I, Cao, you are too dedicated, you are trapped in the laboratory and do not forget to save mankind: "Doctor, don't be in a hurry, and it's too dangerous here!" ”

"No, no, no, it's safe here, and you'd be hard-pressed to find a second living threat other than this lab cat." Osman smiled and said, "And there is a lot of experimental equipment here, I can't leave!" ”

This requirement is a bit difficult to do, not to mention whether what the doctor said is right or not, this university town alone is dangerous enough, there are at least tens of thousands of zombies here, can it only be studied here in the future?

"Otherwise, I still have a few friends outside, I'll call them in, and the food is outside, so I can rest assured that you are with me." Zhao Yu decided to cling to Osman first, and he is now the boss.

"OK, as long as you don't leave it all!"

Next, Zhao Yu took everyone to the underground laboratory, and the vehicle was parked at the door, in order to prevent it from being vandalized, Zhao Yu also attracted some zombies to act as guards.

Closing the door, Zhao Yu led everyone to sweep the experimental building again, three floors above and two floors below, a total of five floors, except for a few zombies, there are two experimenters who survived, their common characteristic is that they hide very well.

Everyone gathered on the second basement floor, Dr. Osman's laboratory, the door of this laboratory was very thick and soundproof, according to the doctor, without this door he would have died.

Osman then recounted his experience during this time to Zhao Yu.

On the day of the accident, Dr. Osman arrived at the lab early, took two assistants to conduct biological experiments together, and closed the door, which saved his own life.

At the beginning of the zombieization, one of the two assistants was transformed, he attacked the other assistant for the first time, biting his neck and not letting go, Dr. Osman, as a doctor of biology, was not afraid of blood, and he was much bolder, he saw that something was wrong, and immediately took the opportunity to use a scalpel, which accurately pierced the zombie's eye socket.

However, the other assistant still died, the major artery was torn and bleeding to death, and the doctor who calmed down wanted to seek help at first, but he walked to the door, through the tempered glass observation port, and saw that it was more dangerous outside, the zombies were chasing the poor humans, and then biting and gnawing on them, blood splattered, and Osman immediately decided to stay in his laboratory.

He used a laboratory cabinet against the door of the laboratory, then thought for a moment, used the clothes on the dead zombie's body, tore it into strips of cloth, and tied the dead assistant to the operating table, he felt that this scene was too much like a zombie movie, so the corpse must be dealt with, don't bite yourself to death.

It turned out that he was right, and after half an hour the corpse showed a slight change, and after an hour, it began to convulse and struggle, and then opened its gray eyes again and let out a roar!

The doctor calmed down for an hour, he first stuffed the cloth into the zombie's mouth to prevent the scream from attracting other zombies, and then began to spray formalin to cover the smell of blood, which also slowed down the decay of the zombie corpse, did not cause odor pollution, and reduced the possibility of causing illness.

After doing it, the doctor began to study the zombies by slicing, he was very calm, and did not think about going out to find a way out, this is the University of Pennsylvania, such a big thing happened, this university must be at the top of the army's rescue list, not to mention that he is the counterpart major, there are also several state-advanced experimental equipment here, there will definitely be rescue!

If there are no mutant zombies, then he is all right, but unfortunately this zombie world does not follow common sense, the army is too busy to take care of itself, the government is completely paralyzed, and the strength of the mutated zombies shocks everyone, and there will be more terrifying high-level mutant zombies after that.

"So you're here waiting for help? What have you eaten during this time? There's no food in the lab, right? Tom asked curiously.

"Haha, you're wrong, this is a biological laboratory, of course there will be experimental animals!" Osman said proudly: "I have a lot of mice and a few little white rabbits here, but unfortunately they died at the same time as the zombies appeared, and I roasted them with an alcohol lamp that day, and then put them in the freezer with backup power. ”

。。 Speechless, it turns out that there is still this kind of operation.

"You're not afraid of getting sick after eating." Zhao Yu asked, the animal that died of illness, said to eat it, in case it turned into a zombie after eating, where would you cry?

"Don't worry, I've done experiments, the virus of zombie meat begins to inactivate at two hundred degrees, and it will die at three hundred degrees, not to mention animals that die of disease, and I won't have a problem cutting into slices and roasting them, but it's amazing that living zombies, that is, my assistants who came back from the dead, have a certain patience for flames, and their blood has a magical ability to recover injuries!"

"That's true, I've found out about this, and I've found that zombies can live for a long time without ingesting flesh and blood, and it seems that the consumption is very low, or they have another source of energy!" Zhao Yu voiced his findings and questions.

"Huh? Is that so? But my assistant is dying of hunger? The doctor gestured to the zombie tied to the chair, "It used to be a chubby man, but now it's skinny, although it may have something to do with me hurting it repeatedly?" ”

Zhao Yu looked at the poor zombie, it was indeed very thin, and it felt that the energy inside was exhausted, but he didn't have any idea about it, so he skipped the topic: "Let's not talk about this first, how are you sure that the cat doesn't eat zombies?" So where did the zombies go here? ”
