Seeing Qi Dong's gradually cold eyes, Mr. Mu remembered that his life was still in the hands of the other party.

After thinking about it, Mr. Mu sighed and continued: "Actually, the volunteers I am talking about are all people who have come to me for refuge, and after I sent out the invitation to volunteer, they all contributed some of their own blood. ”

"Of course, I didn't force them, but they did it of their own free will."

"And there are a lot of people who don't donate blood, and I let them go."

"The reason why I said that there are zombies and volunteers in this blood is that I found that the blood of some people seems to have an immune effect on the zombie virus."

"Immune?"

Hearing Teacher Mu say this, Qi Dong's eyes couldn't help but light up.

"That's right!"

Teacher Mu nodded, and then said: "I have caught a few people who have been infected but have not yet been alienated, put them in captivity, and studied the symptoms of their mutation one by one, not to mention, I really let me study them." ”

As he spoke, Teacher Mu waved his hand at Qi Dong and the others, motioning for them to go to the third basement floor.

As soon as he entered the staircase on the third basement floor, Qi Dong smelled a particularly familiar smell.

Corpse stench and putrid stink!

This is a unique smell on zombies.

After dealing with zombies for so long, Qi Dong has gradually adapted to these tastes.

"You're keeping zombies in captivity here?"

"Eyesight."

Hearing Qi Dong's words, Mr. Mu's eyes were slightly the same, Qi Dong did not enter the third underground floor, but he had already told his secret here, which showed that the young man in front of him should have dealt with zombies a lot.

"You should know that the reason why these people have become zombies is actually because of genetic viruses."

"These genetic viruses are transmitted through blood, enter the human body, and then change the original genetic structure of the human body, completely evolving them into devils who can only eat people."

"Not bad." Where did Qi Dong understand this, but for the sake of face, he followed Mr. Mu's words and took it down.

"However, have you ever observed that not everyone will become zombies as soon as they are infected."

As soon as Teacher Mu's words fell, Qi Dong's body was stunned.

He seems to be right!

The first thing Qi Dong thought of was Chen Kun of the Seventh Rescue Squadron, that kid seemed to have persisted for a long time, and it was not until the last moment that he became a zombie.

Seeing Qi Dong's body's reaction, Teacher Mu had already guessed that Qi Dong should have seen this kind of situation, and continued: "So I collected the blood of these zombies, invited a group of volunteers, and did an experiment. ”

"The general content of the experiment is to imitate the whole process of the zombie virus spreading in the blood."

"You succeeded?"

Qi Dong now believed in the old man in front of him, and couldn't help asking.

Teacher Mu shook his head and said with a wry smile: "How can it be so easy. ”

"I failed."

"Although there is blood that can delay mutation in the blood of these volunteers I collect, in the end, all the blood is also assimilated by the zombie virus."

"In other words, although some people have strong immunity, they still end up losing in the hands of the zombie virus."

"Although these people will delay the time for them to become zombies, they will still go down the same path in the end, it's just a matter of time."

Hearing Teacher Mu's answer, Qi Dong sighed helplessly.

Sure enough, he was still thinking too simply.

At the same time, he had a strange feeling for Dr. G.

can create a plot that can only appear in this kind of movie at such a young age, and he has indeed achieved the degree of excellence in the field of viruses or genes.

"Still, my direction is fine."

Seeing Qi Dong sighing, Mr. Mu threw another bombshell.

"I've experimented on all kinds of animals, those animals with low immunity, after being infected by the zombie virus, I injected those resistant blood into their bodies."

"Guess what's the result?"

Teacher Mu seemed to be offering a treasure, and leaned in front of Qi Dong and said in a low voice.

Qi Dong shook his head when he heard this, in fact, he already had the answer in his heart, but in the field of academics, it was better to make fewer remarks if he didn't understand.

When I got it, I made a joke myself, and there was no way to end it.

"Those infected people who were supposed to turn into zombies immediately turned out to be really delayed for a certain amount of time."

"So I'm thinking, if we really find blood that can resist the zombie virus, and through continuous experimental testing, analyze the content of the components in this blood, will we be able to make a serum that can eliminate the zombie virus?"

"Damn, you're a fucking talent!"

After listening to Mr. Mu's plan, Qi Dong's eyes suddenly lit up.

I have to say that Mr. Mu's behavior is very bold, you must know that if you fight with the evil dragon for too long, you will become a dragon yourself.

If he goes against Dr. G and lets the other party know, will he become a person like Dr. G himself?

"Look at this, his name is Ah Fei, and he is my No. 1 test subject."

"I injected him with all kinds of antiviral drugs, but they didn't do it at all."

On Qi Dong's left side, there was an iron cage in which a naked zombie was kept, but he was sitting there quietly at this time, and he didn't become restless at all because of Qi Dong's arrival.

"Therefore, none of the antiviral drugs currently on the market are effective against the zombie virus."

"Look at the second one."

Teacher Mu pointed to the second cage again, where a middle-aged woman was being held, also naked, but after Qi Dong walked in front of her, this woman actually came to the iron gate and stretched out her hand to Qi Dong, as if she was sending a distress signal to Qi Dong.

"This woman, I used the blood of volunteers to inject into her body, it has been seven days now, his body has begun to have some alienation, but he doesn't understand, and he can still keep his mind running normally, but the only pity is that she has lost her language system and has become a mute who can't speak."

"Hmm."

Qi Dong nodded again, to be honest, he and Xu Qian could only understand a general meaning, and he was too lazy to know the specific real principle.

"The third..."

Before Mr. Mu could introduce him, Qi Dong walked quickly to the iron cage.

But when he saw the people in the cage clearly, the whole person was stunned in place.

He didn't see his former friend, but he did see a little girl about six or seven years old in the third cage.

Following Qi Dong's gaze, Xu Qian was also stunned.

She raised her head and looked at Teacher Mu with some disbelief.

"This ......"

"She's also a poor child, not long after she was infected by zombies, I brought it back from the Green Mansion."
