How Come I Am the Reincarnation of Xiang Yu?

My name is Xiang Hongyu, an ordinary college student. My hobby is reading historical novels. I go to bed late and get up late every day. I am determined to be a good person in society. No ambition is my motto. But on April Fool's Day, everything changed. Yes, my surname is Xiang, and my name contains "Yu", but Xiang Yu's original name is Xiang Ji, how come I am the reincarnation of Xiang Yu? And that woman surnamed Liu, don't pull me away, I'm not going to participate in any war!
