Cultivation World Simulator

An AI-driven cultivation world simulator that aims to create a truly living, immersive xianxia world.

Overview

Cultivation World Simulator combines traditional game-rule systems with large language models. By first establishing a complete ruleset for the cultivation world, it creates an autonomous, vibrant, immersive virtual world with emergent stories.

Core idea: Build a credible rule-based world model first, then plug in AI to bring it to life.

Tech Stack

• Frontend Rendering: pygame (Web support in the future)
• Simulation Engine: custom event-driven simulator
• World Model: rule-based deterministic systems
• AI Integration: LLM-generated actions, decisions, micro-stories

Background

I have been a long-time reader of xianxia novels, from classics to modern works. As a game AI practitioner, I believe today’s LLM capabilities are sufficient to support a xianxia-style world simulation.

However, LLM-only NPC decision/dialogue is not enough. A credible rule system must ground the world as the “world model”, and then AI makes it vivid.

I aim to create a pure, joyful, direct, living sense of immersion. Not a mere marketing demo, nor purely academic like “Stanford Town”, but a world that players can actually feel and inhabit.
