I Am Both the Emperor Wu and the God of Killing

My name is Luo Chen, I am the most handsome guy from the street corner barbecue stall, and I work part-time as a rag picker. Who would have thought that I was once the unparalleled Martial Emperor in another world, and the only killing god to climb out of purgatory? I kept my name anonymous and just wanted to be a happy street kid, until that day, a group of blind gangsters took away half of the spiritual stone I picked up. They didn't know that this robbery had pierced the entire underground world.
