Douluo, to Childhood

As for my childhood and youth, there was cp, no system, time travel, no rebirth, no plug-ins, dual protagonists, character nicknames and classes came from my school life. I could write some characters in childhood games, of course they were just borrowed names. The world view is based on the real world view plus the existence of martial arts. It is independent of the original world view, and of course there is the world of gods.
