# 龙云梦·炎龙封印（二进制版） / Dragon Cloud Dream: Flame Dragon Seal (Binary Edition)

> slug: `longyunmeng_binary` · browser status: `playable` · native port: `40391`

Version 3.5 of Wenwu's "Sunset Reappears: Flame Dragon Seal" (夕阳再现之炎龙封印), as it ran on the "Jiangxi Station One" server in 2006: an earlier state of the same game as the source edition 033-2 (longyunmeng). A wuxia MUD with a fantasy layer: besides strength, aptitude, constitution and agility, every new character picks one of eleven elemental magic talents (light, earth, fire, water, wood, wind, thunder, spirit, darkness, space, metal) that can shield them in combat. New characters start at random in Yangzhou, Beijing or a frontier town in the far northwest, and can join some twenty sects, among them Shaolin, Wudang, Emei, Huashan, Mingjiao, the Ancient Tomb, the Beggar Clan and Peach Blossom Island. Outside the towns lie a fifteen-level underground labyrinth, the twelve Golden Zodiac Palaces, Zhu Changling's Red Plum Manor and the Misty Forest, a 1,500-room maze rebuilt at random every fifteen hours; experience buys levels and attribute points, and there are seclusion training, a lottery, auctions, player gangs and a monthly Huashan sword contest.

## 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_binary.zip` from the URL above (or clone
   `https://github.com/fluffos/mudlibs` and use `libs/longyunmeng_binary/`).
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 `127.0.0.1:40391`.
