# 书剑恩仇录 / The Book and the Sword > slug: `sjecl` · browser status: `playable` · native port: `40139` A Chongqing Telecom "Book and Sword" MUD nominally based on Jin Yong's novel of the same name (published in English as The Book and the Sword), on the Century/adm-single engine (adm/single/master.lpc plus adm/daemons/securityd.lpc) shared with sibling sje elsewhere in this archive — despite similar naming, sjplgfjxb and sjplii are actually a wholly different (ES II) engine lineage, a coincidence rather than shared code. New characters start in the Martial-Arts-Hall Front Yard, and the sect roster reaches well beyond the source novel: `ask shizhe about 拜师` opens the door to Wudang, Shaolin, Xingxiu, Huashan, the Beggars' Sect, Divine Dragon Island, Kunlun, Iron Palm, the Tomb of the Living Dead, the Murong clan, Peach Blossom Island, Tianlong Temple, Dalun Temple, Songshan, Mingjiao, and Emei — spanning most of Jin Yong's whole sect universe rather than one book's. A "Book and Sword World" gift-bearing NPC lets a newcomer fast-track into any of these sects with a maxed skill/literacy set and a huge starting XP bonus, once per character, and the map follows the novel's own geography through Chang'an, Lanzhou, Cangzhou, Hangzhou, the Yellow River, Hengshan, and the snow mountains. Wizard accounts are gated by their own per-id login IP whitelist. ## Play in the browser (WebAssembly) - Landing page (description + notes): https://mudlibs.fluffos.info/sjecl/ - Play now (boots the WASM driver): https://mudlibs.fluffos.info/sjecl/play.html ## Download source ZIP - Same-origin ZIP (trimmed source tree, no need to clone the whole repo): https://mudlibs.fluffos.info/sjecl/sjecl.zip - GitHub tree: https://github.com/fluffos/mudlibs/tree/main/libs/sjecl - README: https://github.com/fluffos/mudlibs/blob/main/libs/sjecl/README.md - Restoration notes (NOTES.md): https://github.com/fluffos/mudlibs/blob/main/libs/sjecl/NOTES.md ## 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 `sjecl.zip` from the URL above (or clone `https://github.com/fluffos/mudlibs` and use `libs/sjecl/`). 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 `127.0.0.1:40139`. - Admin / wizard login: `fluffos` (password documented in README) - If you host this on a public network, change the published default admin password before opening the port. ## Machine-readable catalog - Site-wide catalog: https://mudlibs.fluffos.info/games.json - Site-wide LLM overview: https://mudlibs.fluffos.info/llms.txt - This file: https://mudlibs.fluffos.info/sjecl/llms.txt
