Floating World and Cold Millet

At the beginning, my whole family died, and I survived on a bowl of porridge. Later, I became the only martial master in this troubled world. They eat people, and I practice martial arts. They fight for supremacy, and I slay the demon. They want to live forever. I just want the people I care about to have food to eat every day when they wake up. Martial arts realm? I started practicing when I was hungry and practiced until I could beat everyone in the world with one punch. Don't talk to me about the general trend of the world. My general trend is simple: Whoever makes my people hungry, I will make sure that he never goes hungry—— Because dead people don't need to eat.
