Black Knife Goes to the End of the World

The heroes of the world always want to be happy and vengeful, and become a martial arts hero or a martial arts leader for status and popularity. I, Dong Er, am just a native of the countryside in the countryside of Bianliang. I have just gone through the Anshi Rebellion. I have lost my land and my parents, but I have a black iron sword. Fortunately, I can make a living, and when I can collect enough property, I can own ten acres of fertile land, and live out my old age peacefully. I don't have your grudges and grudges, nor do I have your dreams of being a hero. I just want to make money and support my family, and it's enough not to cause any harm.
