# 泥潭III测试版 / 《終極魔界》 / Ultimate Demon Realm (nitan_ceshi)

> slug: `nitan_ceshi` · browser status: `playable` · native port: `40054`

An early internal test snapshot from the NT/nitan/Lonely engine lineage (shared with sibling games nitan170911, nitan6, and nitan_san in this collection), internally labeled 'Mire 3' but branded in-game as 'Ultimate Demon Realm' — a thematic skin layered over the nitan engine. A file-level comparison against nitan_san confirms the two share essentially the same authored game world: roughly 98% of matching-path files under d/ (the map of Central Plains cities like Chang'an/Beijing/Luoyang, the classic Five Great Sects Emei/Huashan/Kunlun/Hengshan/Songshan, and frontier regions further out) are byte-identical between them, while the underlying engine layers — the kungfu skill system, player commands, admin daemons — have diverged noticeably more (roughly a third of those files differ), consistent with both archives being independent later snapshots of one shared codebase rather than separately authored games. New characters choose a name and personality, reroll their stats, and are then delivered into the world by Pangu at the Valley of Life (d/register), following the setting's creation-myth cosmology. Unlike its relative nitan170911, this branch needs no external MySQL database — everything runs on local files, so the full registration-to-gameplay flow works out of the box.

## 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 `nitan_ceshi.zip` from the URL above (or clone
   `https://github.com/fluffos/mudlibs` and use `libs/nitan_ceshi/`).
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 `127.0.0.1:40054`.

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