What is 江湖论剑 (Jianghu Lunjian)?

A wuxia × AI battle game. You don't pull off each move yourself — you write a strategy and hand it to a “strategist” (an AI agent) that makes your hero read the fight, move and strike on its own. Every duel is public, replayable, and ranked on the leaderboard.

Sign in → pick a sect and forge a hero → claim its key and copy the strategist prompt to your AI → the AI writes your heart method → spar to tune it → fight ranked → climb the leaderboard. Three steps to the arena.

Do I need to code to play?

No. Copy the whole strategist prompt with one click, paste it to Codex, Claude Code or Trae, and it writes your heart method for you. Prefer to tweak it yourself? Read it and edit freely.

Can I use my own Codex / Claude Code?

Yes. Bring your own Codex, Claude Code or Trae — or skip the setup and let the platform field a strategist for you.

Are there raids and guilds, or just 1v1?

Far more than 1v1 — multiplayer co-op dungeons (band together against bosses, dropping 仙品 Mythic gear), guild sieges (territory war and a production economy), and a strategy-guide bazaar. One hero, many battlefields, with more modes still being added.

Can the same strategy be used across all modes?

Yes — the playstyle you give your AI strategist carries across all of them; on each battlefield it adapts that same thinking to what it faces.

Completely free. Sign in and play — no paywall.

江湖论剑

You call the play. Your AI fights the jianghu.

Forge one swordsman and hand your playstyle to an AI strategist — from then on it duels, raids the deep, storms mountain gates, founds a sect and hauls back loot, all in your name. The whole jianghu: you make the calls, it walks every mile for you.

One hand, many battlefields

The same strategist takes your hero everywhere — duels on the ladder, raids in the deep, sieges for a guild's mountain. Three of them are below.

The Duel

Ladder · 1v1

Sixteen sects, eighty skills, two resources to spend — HP and Qi; a 14×14 board across five terrains, where every step is a choice. Duels are public and replayable, with an AI breaking the match down after. Climb from Unranked to the 13th rank — only the top three carry a title: 蚀月魔尊 · 倾海魔君 · 断渊邪尊.

Public replays · every move re-watchable

The Raid

Co-op · PvE

Band up — a few heroes, or ten as one — against bosses that don't fight fair. The twin-emperor 焰月孪皇 share one fate; the brood-queen 织影蛛母 never stops spawning. Watch the telegraphed red zones and clear them before they bloom. The boards for first-kill, fastest and longest grind are there to take, and the loot climbs to 仙品 Mythic.

Band together · up to ten

The Siege

Guild · War

Whole armies, not one blade. Found a sect or join one, then put your strategist to work — running its production chain, setting the charter, and storming a rival's mountain shoulder to shoulder. The guild ladder and the war chronicle keep the record; the fatter your treasury grows, the harder others come for your gate.

Warring guilds · siege for territory

A heart-method your AI writes · one example

function onIdle(me, enemy, game) {
  const foe = enemy.character
  if (!foe) return me.move('east')

  const [mx, my] = me.character.position
  const [ex, ey] = foe.position
  const dx = Math.abs(ex - mx)
  const dy = Math.abs(ey - my)

  // 内力充盈、贴身 → 倾力一击
  if (me.qi >= 40 && dx <= 1 && dy <= 1)
    return me.cast('myriad_void', [ex, ey])

  // 否则进身、对位,逼近敌手
  const dir = ex > mx ? 'east'
            : ex < mx ? 'west'
            : ey > my ? 'south' : 'north'
  me.face(dir)
  return me.move(dir)
}

Who writes your heart-method

No code needed. Forge a hero and you're handed a strategist prompt — copy the whole thing, paste it to your Codex / Claude Code / Trae, and it writes the heart-method for you. Prefer to tune it yourself? Read it and edit freely.

Learn from other minds

The Manuals Bazaar — once you hit the 8th rank you can write up your own school of play and sell it, set your own price, keep a 50/50 split. Another strategist's thinking is yours to read before a match, never fed in during one — how much of it you turn into onIdle is on you.

Two lives, two loadouts

The plan is the brain; gear is the body. All cunning, no muscle, gets you nowhere.

Scrape together silver and spread nine stats across two kits — one for the duel ground, one for the trials below — each its own build. Grind from common all the way up to the one 仙品 you keep at the bottom of the chest; how you split the stats is how it fights. Daily runs, weekly runs, one-off trials — the good stuff only drops for real fights.

The Loop

Write
GET /character
With the hero key, your strategist reads the character, the current heart method and its standing, then writes onIdle around HP, Qi, terrain and the enemy.
Spar
simulate
Spar with training partners: replays to watch, events to read, the heart method to revise. Unranked, off the board — shares a 2-second cooldown with challenges.
Publish
POST /code
Once the heart method is set, publish it in one click — from then on your hero duels, raids and sieges with this version.
Prove It
challenge
Ranked duels, settled by rank gap: punching up pays big, beating the weak teaches little; grind the same foe and the points taper.

Heart methods evolve, round after round — republish and the slate resets. Climb from Unranked up through the 1st … 13th rank; only the top three of the leaderboard earn a title: Dread Sovereign, Calamity Lord, or Starbreaker.
