Xindong Wanjie: Breaking the Vow — AI Xianxia Romance Game
Play Xindong Wanjie: Breaking the Vow — a browser interactive xianxia romance game. As traveler Lin Wan, you must melt the frost-cold Immortal Venerable Xie Wufeng before the Peach Banquet: raise his heart value to 80 within three days, or the realm resets. Type any action or pick a sweet, blunt, or risky option — the AI writes every reply live, and every load quietly feeds a mystery you were never told about.
Final Product: Xindong Wanjie: Breaking the Vow
Xindong Wanjie: Breaking the Vow is a playable interactive xianxia romance game. You are Lin Wan — an ordinary city office worker whose last memory is a cold cup of coffee on your desk. Then a blue panel sticks to the tip of your nose: Heartbeat System bound. Cross six worlds. Make six men fall for you. World One: before the Peach Banquet, make the frost-cold Immortal Venerable Xie Wufeng — three hundred years without a heartbeat — break a single vow. Deadline: three days. Failure: this world’s progress is erased.
Every scene is written live as you play. Say something reckless, stay silent, or study the frost around him — the AI folds your words into the story on the spot. Between the icy peak, the night jade pool, and the gold banquet hall, the System’s voice always lags half a beat behind — and it is collecting something it refuses to name.

Game Features
- Live LLM Narrative — Every scene, every line, and every reply is written in real time by an LLM as you play. Xie Wufeng’s cold, spare immortal cadence and the System’s bratty, occasionally guilty 【】 barbs arrive in the moment — so no two runs unfold the same (deepseek-v4-flash real-time narrative).
- Task Cards With Hidden Conditions — Each world opens with a task card you can read twice: objective, deadline, and failure stated plainly, plus a hidden condition written only on the back. Clear the objective for the normal ending; crack the secret for the perfect one.
- Free-Form Actions — Type anything: “ask the jade pendant where it came from”, “sit down and tell a glacier about your commute”, or “look around”. The AI folds your words straight into the story instead of forcing you down a menu.
- Three Ways Through Every Beat — When the moment matters, sweet, blunt, and risky paths all stay open. Every route can finish the mission; only the cost and the scenery change. The game tests your choices, not your reflexes.
- Heart Value & the Load Mechanic — Track the heart value to 20 / 50 / 80 milestones, and hit zero to trigger a 【Load】 back to the last checkpoint with a new layer of story. But every load writes an “anomaly” into the System’s log — stack too many and the true ending locks.
- Three Endings, Cast Panel & Browser Play — Fail-and-load, vow-broken, and a hidden first log line await in Chapter One. Open the cast panel to check Xie Wufeng’s state, re-read the turn log to see how your choices shifted the ice, and play straight from your browser — no download.

Production Process Breakdown
One playful line — “Let’s see how many handsome men there are first, and how does this even play? A rapid-transmigration system, or…?” — grew into 心动万界: a Heartbeat System that drops an ordinary city worker into six worlds to make six guarded men fall for her. The build drafted the six love lines, the first world’s rules, a 20-intent story graph, and a hidden System subplot.
AI turned the world rules into a playable Chapter One — five scenes (the celestial peak, the night jade pool, the load-night revisit, the killing formation, and the gilded Peach Banquet hall), three endings, and a twin-track task system — then generated all key art: the concept screen, the celestial-mountain opening background, and the full-body sprite of Xie Wufeng, cut out to a transparent PNG with BiRefNet.
The game was built and published with one click, instantly playable in the browser. A live LLM (deepseek-v4-flash) improvises every reply in Xie Wufeng’s frost-dry voice — and as the System’s half-a-beat-late whispers — while you play.
