From Discarded Son to Unrivaled Power Minister

What’s it like to suddenly transmigrate into the body of a simpleton, with your father looking down on you from the start and your older brother picking on you? No problem.

Could you stop beating us up in court?” The enemy kingdom: “Good simpleton, we’ll give up three cities. Please don’t mess with us, okay? Go pick on another country instead.”
