Psychosis: Preventing the Apocalypse

The protagonist is a mentally ill person, one who only appears after being stimulated. Instead of time travel or rebirth, there will be other similar characters in the book who also try their best to prevent the apocalypse from happening. Of course, there are also those who are reborn or travel through books and try to stock up on goods to survive. Many powerful countries in this world are also preventing the apocalypse, and the country where the protagonist is located is of course included... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
