After Kicking Out My Father, I United the Empire Myself

Su Yu transmigrates as the crown prince of the Great Xia Kingdom, but he gets stuck with an unreliable father.

To keep foreign nations from invading, his father adopts a policy of isolation and cuts off all contact with the outside world. With banditry rampant across the provinces, his father establishes provincial military governors, throwing local military power out of control. To rein in the governors, his father then enfeoffs various princes, only for each prince to carve out territory and rule independently!

Watching all this unfold, Su Yu sighs helplessly. “A foolish ruler who doesn't try is bad enough. One who tries foolishly is even worse!” So he personally boots his father off the throne. I will unify this realm myself!
