You Are Not a Cultivator. You Are the Heavenly Dao.
AI Cultivation World Simulator is an open-world xianxia simulation game powered by Large Language Models. Unlike traditional RPGs, you don't play as a single character — you play as the
Heavenly Dao, the governing force of the universe.
Observe countless cultivators from a god's perspective. Watch them strive, scheme, fall in love, wage war, and reach for immortality. You may sit back and watch the world evolve on its own — or subtly intervene: send down tribulations, twist someone's heart, and alter the course of history.
Core Features
- Play as God — No combat grind. No single hero. You are the silent force behind all things.
- Every NPC is AI-Driven — Each character is independently powered by an LLM with their own personality, memory, goals, and relationships. They form alliances, hold grudges, and make decisions that surprise even the developers.
- Emergent Storytelling — No preset script. Sect wars, betrayals, and legendary breakthroughs all arise organically from the world's own logic. Even we don't know what happens next.
- Rigorous Cultivation Rules — Spiritual roots, cultivation realms, techniques, lifespan, elixirs, and spirit stones form a coherent framework. AI creativity is grounded in real xianxia logic.
- Fully Customizable LLM Backend — Connect DeepSeek, Ollama, or any OpenAI-compatible API. Use your own model.
What You'll Witness
- A prodigy with a five-element spiritual root rises from obscurity to challenge the heavens
- Two sects wage a century-long war over a single spiritual vein
- A ruthless elder secretly poisons a rival disciple — and faces karmic retribution
- A wandering cultivator falls in love, abandons the pursuit of immortality, and grows old in a mortal village
None of this was scripted. But all of it is possible.
A Living Xianxia World
Inspired by classic Chinese cultivation (xianxia) fiction, this simulator aims to recreate the rich, sprawling worlds of those novels — not as a story told to you, but as a
world that lives and breathes beside you.
⚠️ Please Read Before You Play
This game is a
work in progress developed by a solo indie developer and is
completely free. Due to limited resources, you may encounter various bugs including save file corruption, UI glitches, and logic errors.
Encountering bugs is entirely normal, and fixes are not guaranteed. Please make sure you are comfortable with this before playing.
This game requires a
reasonably capable LLM (e.g. Gemini Flash / Qwen Flash tier or above) to function properly. Token consumption can be significant — please keep an eye on your API usage costs.
Your API Key is stored
locally on your machine. Never share your local config file with others. It is also recommended to set a
spending limit in your LLM provider's dashboard as a precaution.
Please ensure you do not violate local laws, regulations, or public order.
