# 天下无雪 / A World Without Snow

> slug: `tianxiawuxue` · browser status: `playable` · native port: `40045`

Self-titled "A World Without Snow," credited to an author known as "Dream" with an acknowledgments list naming several fellow wizards (Poor, Sinb, Lonely, Zjb, among others) — a long-running Chinese wuxia MUD with its own distinct setting. Its map, however, turns out to share deep roots with this archive's "Tianya" (Horizon) lineage: several scenes, including its "Peak of the World" cliff-jump location, are byte-for-byte identical to areas in other differently-branded games in that lineage — a connection no prior entry in this archive had documented before. One of its credited wizards, "Lonely," is also the author of the Nitan series, hinting at genuine code and personnel exchange across this wider MUD community.

## 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 `tianxiawuxue.zip` from the URL above (or clone
   `https://github.com/fluffos/mudlibs` and use `libs/tianxiawuxue/`).
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 `127.0.0.1:40045`.

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