# 郑州风云3 / Zhengzhou Storm 3 > slug: `zzfy` · browser status: `playable` · native port: `40025` Introduces itself in-game as 'Invincible Under Heaven' (the collector-assigned title 'Zhengzhou Storm 3' names this particular server instance). Part of the Fengyun ('Storm') engine family, alongside this collection's fy2/fy2005/fengyun434/moniHuafu, and — a relationship neither archive previously documented — a near-duplicate of this collection's other 'Zhengzhou Storm 3' entry, zzfy3: the two work trees are 10,345 files each and only 163 differ, and both in turn share the same 'Zhengzhou Storm' map and marriage system (confirmed via a byte-identical d/marry/hongniang-zhang.lpc matchmaker NPC) with this collection's wqfy ('Heartless Storm', same 'Invincible Under Heaven' banner). The game bills itself as 'a MUD set in the world of Gu Long's novels' — rather than the Jin Yong-flavored wuxia common elsewhere in this collection, it leans into Gu Long's brisk, devil-may-care style of jianghu storytelling. Character creation lets players choose an ethnicity (Han, Miao, Manchu, or Mongol), and the same underworld death/revival ritual found in zzfy3 — a five-stage dialogue with Judge Cui Jue at the gates of the underworld, with ghosts free to wander rather than being locked in place — is present here too. ## Play in the browser (WebAssembly) - Landing page (description + notes): https://mudlibs.fluffos.info/zzfy/ - Play now (boots the WASM driver): https://mudlibs.fluffos.info/zzfy/play.html ## Download source ZIP - Same-origin ZIP (trimmed source tree, no need to clone the whole repo): https://mudlibs.fluffos.info/zzfy/zzfy.zip - GitHub tree: https://github.com/fluffos/mudlibs/tree/main/libs/zzfy - README: https://github.com/fluffos/mudlibs/blob/main/libs/zzfy/README.md - Restoration notes (NOTES.md): https://github.com/fluffos/mudlibs/blob/main/libs/zzfy/NOTES.md ## Run natively with FluffOS 1.

Download and unzip `zzfy.zip` from the URL above (or clone `https://github.com/fluffos/mudlibs` and use `libs/zzfy/`). 3. From the unzipped lib directory, ensure `config.fluffos` points `mudlib directory` at this tree (the checked-in file may contain a maintainer-local absolute path — edit it to your extract path). 4. Start the driver: ```bash /path/to/fluffos/build/src/driver config.fluffos ``` 5.
