I Have a Sword at the Beginning

An illegitimate child was considered a waste by everyone. He suffered humiliation, bullying, ridicule and even abuse. He remembers those people clearly. When he comes back in this life, he must settle all the accounts he has made! I have a sword that can make all sects kneel down and worship me. I have a sword that can make everyone in the world surrender to me. I have a sword that will make the entire empire worship me. I have a sword that can shake the heaven and the earth!
