You Loong

You Loong, Leader of the Blackwater Crew, is an optional Phantom Blade Zero boss fought twice, first in the water deep below Pangzhen and later at the Blackwater Crew Dock on Meigu Lake. Watch the bubbles when he dives, parry his blue-glint slash and dodge through his water jet. He drops You Loong's Deluge, then the Loong Trident.

Watch the bubbles: You Loong, Leader of the Blackwater Crew, fights from a shallow body of water in Pangzhen and comes up out of it with his heaviest attack, so the trick of this optional boss is tracking where he will surface, parrying his one blue-glint slash and dodging through his water jet. Maxroll calls the first fight, down the left fork after the Green Serpent House, "a pretty simple encounter" whose Black Flash attacks catch you off guard, and he returns at Meigu Lake as You Loong, the Frenzied Blackwater Crew Leader. Turning the Tide, the achievement for beating him twice, went from 18.6% of Steam players on Nov 4 to 31.6% on Nov 9, 2026. His first drop, You Loong's Deluge, is a Phantom Edge that puts out fire.

The first fight is knee-deep: at 0:11 of PowerPyx's Oct 29, 2026 recording You Loong leaps out of the flooded street over Soul's head, with floating lanterns on the water and half-sunk houses behind him.

Two arenas: Pangzhen and Meigu Lake

In Pangzhen: at the fork after the Green Serpent House, go left and "walk into the water". AllThings.how places the arena deep below Pangzhen, about 138 m from the Lion Dance Hall bell. PCGamesN says to beat him before the flame mask boss that comes next, Flame, the Lion Dance Grandmaster; Maxroll's route fights him before Chang Hong.

At Meigu Lake: take the boat straight on to the final island, Blackwater Crew Dock. PCGamesN calls it "quite a hidden boss, on an island on the lake, so you may miss it."

Reading the water

Watch the water. Game8 says to pull him out with the Loong Trident when he dives, which stops the devastating attack he makes on surfacing; PCGamesN's advice is to keep an eye on the bubbles. Maxroll and AllThings.how list the Loong Trident as the reward of the second fight, so in Pangzhen the bubbles are what you have.
Fight his flurry from range, then close in for its last thrust.
Look for blue: his two-hit horizontal slash is his only attack with a blue glint.
Dodge through the water jet rather than away from it.
Be ready from the first second at Meigu Lake: PCGamesN warns that "the whole fight starts with a red attack", and that his attacks are otherwise largely the same as in Pangzhen.

Above and below the surface

Dive and surface: he disappears under the water and comes up with a devastating attack. Track the bubbles, or drag him out with the Loong Trident.
Rapid-slash flurry: each swing sends a damaging wave across the water. Game8 says to stay at a distance, block or sidestep the shockwaves, then step back into melee as the flurry ends and perfect dodge his final spear thrust for a Ghoststep counter.
Spinning trident attacks: PCGamesN says a red attack follows them.
Two-hit horizontal slash: blue glint. Parry the second hit for a Ghoststep counterparry.
Water jet: unblockable; he sweeps a cone of water back and forth. Dodge through the beam at any point for a Ghoststep counter that interrupts it, or, as PCGamesN puts it, dodge it and interrupt it by attacking.
Black Flash attacks: the moves that, in Maxroll's words, "can catch you off-guard."

The second fight and its reward

The sources disagree on what the Meigu Lake fight gives. Maxroll and AllThings.how list the Loong Trident Phantom Edge and a High-power Pump; PCGamesN names only the High-Power Pump, the material to Soul Temper You Loong's Deluge. In the house upstairs after the fight, Maxroll finds Blackwater Crew's Memory Flower (2), and a third on the house left of the arena. Master of the Misty Waters rose from 16.8% of Steam players on Nov 4 to 29.5% on Nov 9, 2026, for beating You Loong, Zither Maiden Yan Qiansui and the One-Eyed Archer at Meigu Lake, a shade under the 31.6% with Turning the Tide (Trophies and Achievements).
