He accidentally transmigrates into the turbulent Republican era.
By chance, he gets a System that rewards him with four dead soldiers for signing in every week, stirring up Shanghai.
Then another unexpected stroke of luck: he turns out to be the nephew of the most powerful man in the Republic of China.
After that, everything changes. He stops keeping a low profile, develops industry and Cthulhu technology, and builds an invincible army to protect his country. He fights Japan, pressures Britain, and gets rich alongside those making a fortune from the war.
I’m not good at writing introductions, so please read the story itself. Thank you, everyone.
