Ruled the Heavens from the Beginning of the Dynasty

Traveling through a different world and being reborn, the story begins with the third prince of a real dynasty, and the protagonist is a bit stubborn. I am invincible, you can say whatever the protagonist says "How can you, as an emperor, take action at will? What's the use of having a younger brother?" But I suspect the world is playing me but I have no proof. "I am Lu Bu. I have been ordered by the emperor to come here to destroy the sect. At this moment, I alone dominate the battlefield."
