# 夕阳再现·疯狂江湖 / Sunset Reappears: Crazy Jianghu

> slug: `xyzxfk` · browser status: `playable` · native port: `40040`

The site's subtitle is "Crazy Jianghu." Players begin as an unknown commoner youth dropped into one of several randomly-assigned frontier towns (North Frontier Town, Iron Spear Temple, and others), then build a reputation through sects and martial training in a jianghu that allows open player-vs-player combat. It carries the genuine Sunset Reappears map lineage shared with this project's xyzxfy2, xyzx, jhfy3, xajh4gkb, and xyzxyl201412 (byte-identical d/city/sj.lpc) — a full file-level comparison against sibling xyzxfy2 found roughly 97% of their common world files are byte-for-byte identical, with only small independent additions layered on top (e.g. an extra guild-teleport command), so the two are best understood as parallel-maintained snapshots of one authored map rather than two fully independent games, despite each having its own distinct login/security code. This lineage is distinct from a same-named cluster elsewhere in this collection (xysylmhb, xyzx3, xyzxiiylzymh, etc.) whose maps actually belong to an unrelated "Tianya" family; shared branding here doesn't reliably indicate shared code. Also shares more distant roots with this project's wmkj, jhfy, and bixiecanyang.

## 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 `xyzxfk.zip` from the URL above (or clone
   `https://github.com/fluffos/mudlibs` and use `libs/xyzxfk/`).
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 `127.0.0.1:40040`.

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