Restarting the Dragon Clan: Starting with the Group's Destruction of Otsutsuki

I witnessed the beginning of an era and the end of an era; I once felt inferior and cowardly and had no one to love me, and I also worked hard without caring about the expectations of everyone; I create my future with my own hands, and bury my past with my own hands; I am an old ninja who tries his best to save the world, and I am also a dragon-slaying warrior who is helpless and bears the burden of his sins. My name is Lu Mingfei, my story is long and my life is short.
