I Was Transported into My Own Novel to Defy Fate and Change My Life

Yu Chen accidentally replaced his own name with that of a young prince. He transmigrated and became the "weakest" young prince in his own novel. If he couldn't wake up, he might as well enjoy himself in his own story and rewrite his fate! Become a peerless master, marry the goddess, command a mighty army, and grow richer than any kingdom. It's my novel, so I make the rules...
