# 鳥人世界 (The Bird-Man World) / The Bird-Man World > slug: `niaoren` · browser status: `playable` · native port: `40100` A Traditional Chinese wuxia MUD drawing its plots and riddles from Jin Yong's fifteen novels. Players start out at the Dragon Gate Inn and make their way through sects and cities across the jianghu, training internal power, external martial arts, and other skills along the way — a classic wuxia framework of stats, sects, master-disciple bonds, guilds, and rankings. Its inn's bulletin board still carries real historical player messages — bug reports, quest-balance patch notes, sect gossip — a rare case in this collection of an original community's own history surviving intact. Its lineage traces back to cctx (Chi Cheng Tian Xia), an independent branch of the same source codebase, down to a lingering reference to a leftover cctxinfo file. ## Play in the browser (WebAssembly) - Landing page (description + notes): https://mudlibs.fluffos.info/niaoren/ - Play now (boots the WASM driver): https://mudlibs.fluffos.info/niaoren/play.html ## Download source ZIP - Same-origin ZIP (trimmed source tree, no need to clone the whole repo): https://mudlibs.fluffos.info/niaoren/niaoren.zip - GitHub tree: https://github.com/fluffos/mudlibs/tree/main/libs/niaoren - README: https://github.com/fluffos/mudlibs/blob/main/libs/niaoren/README.md - Restoration notes (NOTES.md): https://github.com/fluffos/mudlibs/blob/main/libs/niaoren/NOTES.md ## Run natively with FluffOS 1.
