Reborn in the Body of a Foolish Prince, I Blow Up the Capital from the Start

One day, he transmigrated and became a mentally disabled prince. It was hell difficulty from the start: assassins, poison, being thrown into a cesspit, and a thousand different ways to die.

He'll turn a barren land into a land of abundance, purge corrupt ministers, seize the crown prince's position, and shake the world!
