Corruptors of Eastern History

Now that I have found the meaning of my existence, nothing matters anymore. I will do my best! Ps: The theme is very clear, which is to change history. Ps: I will try my best not to be stupid wherever I can. Ps: Personally, I prefer mainstream sadism. Although it is a happy-oriented novel, there will be plots where the protagonist is tortured. Well, the main purpose is to torture the protagonist's heart, but the ending will definitely be good. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
