About this game

《Celestial Brush》is an AI-powered wuxia interactive fiction RPG. Every decision you make unfolds as a beautifully written martial arts novel passage — and every chapter weaves together into a legend that is entirely your own. Since AI generation has real computing costs, gameplay runs on a token system (earned via subscription, top-ups, or watching ads) rather than unlimited free play.

[Immersive AI Storytelling]
Each turn, the AI generates a vivid wuxia passage in real time — capturing atmosphere, inner conflict, and the tension of combat. The prose is sharp and classical, evoking the worlds of Jin Yong and Gu Long. Lies can be seen through. Persuasion can fail. Every setback is a turning point, not a dead end.

[Grand Realm · Shared Multiplayer] (Coming Soon)
Write the same living jianghu together with every player on the server — finish your own chapter, then merge your choices into the shared canon through Destiny Return, facing trials of Tianji Wagers and Karmic Reckoning. The path you walked becomes the history the next wanderer inherits.

[Your Story, Drawn Panel by Panel]
Transform any chapter into an ink-brush manga with one tap. AI extracts the scene, designs tension-filled panels, and brings characters, dialogue, and action to life across the page. Completed legends are permanently archived in the Hall of Legends for you to revisit anytime.

[Voice Narration]
Choose from three distinct voice tones and let every passage come to life like an audio drama.

[Choose Your Path, Shape Your Fate]
Three distinct choices each turn: advance the main story, take bold action, or deepen your cultivation. There is no right or wrong — only your unique journey through the martial world. Break through to a new realm and feel the dramatic surge of power that transforms you.

[Multiple Worlds to Explore]
Begin in the wuxia world or the xianxia realm, or build your own unique martial world from the ground up.

[Your Legend Lives On]
Cloud-synced progress follows you across devices. Completed stories and generated manga are preserved forever in your personal archive.

Pick up the brush. The martial world awaits.
