The Carefree Young Prince

A legendary God of War transmigrates to another world and becomes a useless vassal prince of the Great Qin. He has a title but no power? No way! First, he'll seize power for himself! The steppe barbarians are marching south to attack the passes? Battalion Commander, bring out the cannons I just had made. Today, I'll teach you how to fire them! The Xiongnu of the desert want to join in too? Battalion Commander, blast them all as well! The martial arts experts think I'm too cruel and want to uphold justice on Heaven's behalf? Battalion Commander!! Actually, just stand back and applaud this time. I'll take on the whole martial world by myself!
