A Guide to Survival in a Post-Apocalyptic World

My name is Wang Feng, I am seventeen years old and I live in a garbage dump in the container city of Baixiong City. Every day's work is to pick up rags, build equipment, and find ways to survive. By the way, seventeen years ago I went into space and killed the Lord of the Gross Body and saved all mankind. But no one remembers it. Even I almost forgot about it. After all, who would believe that an orphan living in a garbage dump was once the hero of the entire world? In the post-apocalyptic world, I just want to make money and become a salted fish. As for saving the world... Once is enough.
