In Resident Evil One, what was written in the two (The Last Book) that Jill found?

If the person who answered could also explain the contents of the papers that Claire received from the doctor's wife before she died, it would be a bonus! Oh right, in Shengsanli, Jill saw something that looked like a notebook next to the corpse of a mercenary. That person seemed to be the commander of some mercenary. May I ask what was recorded on it? If you can answer it, you can also add points!

Answer 1

In Resident Evil 1, Jill found the two last books.

The first and last book contained some supernatural secrets that Jill could not explain, as well as some explanations about the strange events and supernatural phenomena in this world. This information was very important to Jill because if she couldn't master these secrets, she might lose her superpower.

The second and last book recorded the formula of a drug that Jill and Chris found before the outbreak of Resident Evil that could slow down the spread of the virus. This drug was once studied by a scientist, but an accident occurred during the experiment, causing the drug to fail. Jill and Chris discovered the formula during their investigation and tried to recreate the drug to save the world.
