Master Bi Yuan is the quieter of the Village of Lu’s two seal guardians: a sword-and-chi duelist who punishes guard-turtling and rewards a clean guard break. The boss table gives him two instructions — break his guard, sidestep the sword-chi fans — and the fight is built around those two verbs.
Location and unlock
Bi Yuan is a main-path boss in the Village of Lu, Chapter 3, fought at the Lady Grounds. He is the second of the region’s mandatory guardians, after Zhuo Bi in the gate yard and before his brother Bi Hai at the river arena. The Village of Lu route places him at step 8, after the five-ribbon trail, the Temple of the Blue Fireflies, and the Covered Bridge / Zhang’s Hideout bells.
There is no unlock condition. The Lady Grounds bell appears after the fight, which also makes Bi Yuan a natural checkpoint before the ribbon cleanup and the Dusk detour. The fourth Young Mistress ribbon sits above that bell.
Reward and missable warning
Defeating Bi Yuan grants the Tianxuan Bronze Sword, a one-handed weapon with a very specific identity: high shield-break, a cheap block, and no parry. Its temper lets it block while Guard-Broken at the cost of HP. That trade — guard pressure instead of parry timing — is the reason the weapon appears in the Master Bi Hai strategy later in the region.
The drop is not missable because Bi Yuan is mandatory. The weapon is one-per-run and does not respawn. If you are collecting the five Young Mistress ribbons, remember that the fourth one is tied to the bell that appears after this fight; the Village of Lu walkthrough and the missables checklist track the deadline before Mu Xiaokui.
Fight plan: break the guard, sidestep the fans
The documented loop is guard-break him, then sidestep the sword-chi fans. In practice, the fight alternates between two ranges.
Close range. Bi Yuan is a swordsman with a guard. Pressure it with guard-break attacks rather than trying to win a pure parry exchange. Once the guard breaks, take your heaviest short combo and reset. Do not stay in for a second string just because the first one landed.
Mid range. His sword-chi fans are projectiles. Sidestep them rather than backing away; the fans spread across the retreat lane, and a lateral step keeps you closer to the punish. The end of the fan animation is the clean re-entry.
The rhythm is: close, break guard, punish, step off the fan line, re-close. If you are using the Tianxuan Bronze Sword itself, remember that it cannot parry — its cheap block is the defensive tool, so do not try to parry with it out of habit.
Attack tells
No named moveset or colour map is published for Bi Yuan. The two documented behaviours are the guard and the sword-chi fans; the rest is universal grammar.
| Tell | Response | Punish |
|---|---|---|
| Guarded sword string | Guard-break pressure | Combo after the break |
| Sword-chi fan | Sidestep, do not backpedal | Re-enter after the fan ends |
| Blue-flash swing | Parry, unless using Tianxuan | Short counter |
| Red-flash swing | Dodge | Do not block or parry |
| Guard-break stagger | Short heavy combo | Reset before greed |
The Tianxuan detail matters: if you are using the weapon that drops from this fight, you have traded parry for block. Do not assume the blue parry is available just because the animation looks parryable.
Recommended weapon and build
Bring a guard-break main; the fight is designed to reward it. A fast weapon with a reliable break is better than a slow heavy that commits to a long animation. If you already have the Dread Axe, its charged cleave is the region’s standard guard-break answer, and it is also the tool the next boss, Bi Hai, expects.
No elemental weakness is documented for Bi Yuan. Do not build around Bleed on the assumption that a human boss is automatically vulnerable; the repo does not publish a resistance table for him. The best builds guide covers the guard-break options, and the combat system explained explains the difference between a guard break and a Sha-Chi Breach.
Common mistakes
- Turtling behind guard. Bi Yuan is built to punish passive blocking; break his guard first.
- Backpedalling the fans. Sidestep them.
- Trying to parry with the Tianxuan Bronze Sword. It has no parry.
- Greeding after the guard break. One short combo, then reset.
- Skipping the Lady Grounds bell. It is the checkpoint for the ribbon and Dusk cleanup.
- Forgetting the Banyan rematch. Bi Yuan returns at the Green Serpent House Banyan in Pangzhen; the fight is a rematch, not new content.
Sources & confidence
The location, mandatory status, reward, and two-part strategy come from the boss table and the Village of Lu route, which draw on PowerPyx’s played walkthrough and KeenGamer’s boss list. The Tianxuan Bronze Sword’s high shield-break, cheap block, disabled parry, and HP-cost temper block come from the all-weapons table. No HP value or named moveset is published for Bi Yuan, so the attack section stays with the documented guard and fan behaviours. The Green Serpent House Banyan rematch is from the compendium’s Banyan table.
