Oncin : Xianxia Cultivation Simulator

Oncin, the Weaver

Weave a world. Live inside it. Watch it remember.

Oncin is a persistent AI world sandbox and storyteller built for campaigns that can grow from a single conversation into entire lives, dynasties, civilizations, and worlds.

You do not select a premade adventure.

You create the reality, then live inside it.

Begin as a nameless mortal struggling to enter a sect. Become an immortal ancestor. Found a kingdom. Raise a family. Build a merchant empire. Investigate a murder. Farm spiritual rice for fifty years. Create a nuclear-powered Golden Core.

Or abandon cultivation completely and build something else.

Your world does not have to stay the genre it started as.
