# 龙云梦·炎龙封印（源码版） / Dragon Cloud Dream: Flame Dragon Seal (Source Edition)

> slug: `longyunmeng` · browser status: `playable` · native port: `40094`

By author Wenwu, a fantasy-tinged wuxia mudlib in the "Sunset Reappears / Flame Dragon Seal" (XYZX/YLFY) engine family — an independent branch, related to but separately evolved from this project's ylfyxa3 (Flame Dragon Seal: Smiling Proud Wanderer, Afei Station), not a reskin of the same content. On top of the standard martial-arts attributes (strength, aptitude, bone-structure, agility), characters also pick an innate elemental affinity from eleven "magic talent" elements (light, earth, fire, water, wood, qi, thunder, spirit, darkness, space, metal), blending traditional sect-based jianghu play with a real elemental-magic system across a large world (close to 20,000 files). A wooden training dummy safely mirrors a challenger's own stats for practice duels, sect apprenticeship is a real playable path (e.g. formally joining Huashan under master Yue Buqun), and the gang system tracks each branch's "head disciple" title live as leadership actually changes hands through play. It shares the genuine "Sunset Reappears" code lineage (a byte-identical d/city/sj.lpc) with xyzx, jhfy3, xajh4gkb, and xyzxyl201412; note that several other archives in this project also carry the "Sunset Reappears" brand but belong to an entirely different "Tianya" map lineage, so the brand name alone is not a reliable guide to actual codebase ancestry.

## Run natively with FluffOS

1. Build a current FluffOS driver from https://github.com/fluffos/fluffos
   (native `build` / `build-debug`; see that repo's docs).
2. Download and unzip `longyunmeng.zip` from the URL above (or clone
   `https://github.com/fluffos/mudlibs` and use `libs/longyunmeng/`).
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. Connect a UTF-8 MUD client to `127.0.0.1:40094`.

- Admin / wizard login: `fluffos` / `Mud@2026`
- If you host this on a public network, change the published default
  admin password before opening the port.
