The Crazy Little Duke of the Tang Dynasty

This... This is... The time travel the **boys are talking about? I am... The son of the Duke? When I relive my life, should I continue the martial arts passed down from my family, or should I continue my literary glory in my previous life? No! No! No! A person's life is as long as a tree's autumn. Since God gives me another chance, I will do something! Aye, I want to hit my brother... Hey, don't hit, don't hit, Aye, I was wrong! Saint, I want to hit the prince... Don't... Don't be angry, I just despise him... Don't... I was wrong! Did you hear that? That madman started fighting again! Did you hear that? That madman destroyed another country! Did you hear that? That lunatic made him a Duke! Tsk... I don't do it for the world, I just do it for myself to be famous in the world; I don't do it for the country's wealth and strength, I just do it for my own happiness!
