Zhao Yi did not pay much attention to the small projects in the lab, but he was very interested in the 'anti-infection' issue that was unexpectedly discovered during the experiment process, because research on 'anti-HIV infection' was very valuable.
The blood samples provided by Fan Lei, which had obvious 'anti-infection properties', led to only one conclusion during the research process: they contained 'some sort of infection-related antibody protein.
The scope of this conclusion was too broad.
Which infection?
There are simply too many pathogens in humans. The scope of 'some infection' is too wide while there is stagnation in the variation of samples. It is difficult to support continuous research with a single sample and extremely hard to identify the cause.
Therefore, at the beginning, people such as Ai Lixin and Zhang Wei suggested that it was reasonable to inject Fan Lei with regular viruses and bacteria.
