Sun Ningshan compared the virus isolated from Ji Rao's blood with R bacteria and found that it was a kind of bacteria. Once r bacteria invade the human body, it is a devastating blow to the human body. No immune system works. The death rate is 100%.

But in Ji Rao's body, R bacteria are surrounded by new antibodies.

Naturally, the production of these antibodies varies from person to person. At least up to now, only Ji Rao has these antibodies, but his lineal blood relatives have no such characteristics. Because Ji Rao's parents had already died in that research base when the virus broke out.

It took him two days to isolate the antibody and name it j-antibody. Rare things are usually named after them, and so are j-antibodies.

But he found that the survival conditions of the j-antibody were extremely harsh. He only moved the j-antibody out alone for half a minute, and the j-antibody disappeared.

He also took some blood from a newly zombied man and found that Ji Rao's blood was indeed compatible with R bacteria.

After discovering this, he went to Xia Siyi again.

Xia Siyi has given all the experimental reports of Professor Wu to sun Ningshan for a long time. Sun Ningshan and Xia Siyi had a discussion. Although the young man didn't think about many things thoroughly, he was better than open-minded. Unlike him, many things have been limited in the framework of theoretical knowledge, and sometimes it backfired.

Zhou Xianshan attached great importance to the research of sun Ningshan, and almost responded to every request. In terms of instrument material samples, as long as sun Ningshan spoke, as long as Zhou Xianshan had them, they were all given to him. There were several professors in the national shelter, but in front of sun Ningshan, they all had to fight.

Sun Ningshan attaches great importance to j-antibody. He has to do it in person if he can.

The whole research room was instructed by Zhou Xianshan and followed by sun Ningshan.

Although sun Ningshan is a bit extreme in dealing with problems, his ability is beyond doubt. Especially in the current world, sacrifice is inevitable. It is normal to sacrifice a small number of people to help the majority of people.

Xia Siyi is busy day and night in the laboratory, sometimes he can't close his eyes all day. There are too few capable researchers, so they have to work overtime.

Although he didn't know as well as sun Ningshan, he also knew a lot.

Xia Siyi didn't come out of the laboratory until 12 o'clock that night. He has only slept three or four hours a day for three consecutive days.

When I went back to the dormitory, I suddenly saw a man standing at his door.

Although all generators are accommodated, there is a shortage of resources, there are many people in the shelter, and the lights in the corridor are not on at night.

Xia Siyi stopped and said, "who is it?"

"It's me."

Li Zheng's voice.

Xia Siyi was relieved and went to Li Zheng.

Li Zheng is holding his chest, leaning back against the wall, bending his leg, and looking up at Xia Siyi.

Xia Siyi had a pair of indifferent eyes, and the smile on his face was a little lighter.

"Brother Li, why are you here?"

"I can't get into the lab, how's Ji Rao?"

"That lab is heavily guarded and needs to check fingerprints. People without authority can't get in." Xia Siyi saw that Li Zheng's face was a little heavy. He said hurriedly, "don't worry. Ji Rao has nothing to do these days. He only took a tube of blood on the first day."
