Douluo Dalu: The King Where It All Began

This story is about a man named Ying Zheng, a young man with the same name as the king who unified China. He died as a child and like all isekai stories, he was reincarnated into the world of Douluo with a system. His journey to unify the Doulu continent and become King begins here. Can he do it? I don't know either!
