# 大唐双龙 (DaTangShuangLong) / Twin Dragons of the Tang Dynasty (DaTangShuangLong)

> slug: `dtsl2` · browser status: `playable` · native port: `40043`

An independent server/security-layer fork sharing the SAME 大唐双龙 authored game world as siblings dtsl and dtslmud, based on Huang Yi's novel and set amid the chaos of the early Tang jianghu -- a file-level check found dtsl2's own domain tree (5,095 files) is 99%+ byte-identical to dtsl's (only 4-5 files actually differ, mostly one job NPC and one hub room), confirming these three archives are the same content wrapped in different engines, not independently-written storylines. What genuinely differs here: its own, simpler master.c/logind.c/security model (no deferred security daemon), Chinese names rejected outright if they match the novel's own protagonists (寇仲/Kou Zhong, 徐子陵/Xu Ziling) or real political figures, and new accounts needing over an hour of continuous online time before the first autosave (with an explicit "keep this account?" prompt on an early quit). Same 石龙武馆 (Stone Dragon Martial Hall) newbie hub as its siblings -- banking, `qiecuo` safe sparring, organic `xue`-taught skills, and `bai`/`apprentice` sect-joining through direct gate exits into 阴癸派/净念禅院/突厥/东溟派/慈航静斋.

## 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 `dtsl2.zip` from the URL above (or clone
   `https://github.com/fluffos/mudlibs` and use `libs/dtsl2/`).
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 `127.0.0.1:40043`.
