What is on record
The first of two fights against the Blackwater Crew's leader, in a flooded pond on the west side of Pangzhen. Beating him before Flame gives You Loong's Deluge, the Phantom Edge that puts out fire barriers, including the one by the Marketplace and Flame's fire.
Who he is
You Loong leads the Blackwater Crew and is fought twice. This first meeting is optional, in Pangzhen, and KeenGamer's advice is to beat him before Flame, because his drop, You Loong's Deluge, puts out Flame's fire; its Phantom Edge guide places the fight at the western pond near the Banyan Tree and says the Deluge extinguishes fire barriers, including the one by the Marketplace. The second fight, at the Blackwater Crew Dock on Meigu Lake, is the one that counts for the trophy Master of the Misty Waters (KeenGamer, PowerPyx); OfZenAndComputing calls the lake version the same opponent in a harder form. Beebom lists both under Pangzhen with the details still blank. PowerPyx's capture opens on the Pangzhen map at 27% completion with a Serpent House bell selected.
What the footage shows
The arena is a shallow pond at dusk between reed banks and timber houses, with paper lanterns floating on the water. The name bar "You Loong, Leader of the Blackwater Crew" is on screen from 0:15 to about 2:30. He wears a wide straw hat and fights with a long pronged spear; at 0:25 and 1:00 huge white splashes fill the screen, at 1:15 a teal burst with red through it, and at 1:40 he wades past a floating lantern with the spear levelled. The capture ends at 2:35 with a red burst as he falls.
Attacks
Not on record. No English guide published by Nov 2, 2026 names this boss's attacks or counters; the footage notes above are what this site has seen, and it does not invent tells from them.
Drops
You Loong's Deluge, a Phantom Edge that extinguishes fire barriers (KeenGamer). The High-Power Pump from the second fight is its Soul Tempering material. The Deluge's item card is on screen at 2:36 in PowerPyx's capture.
The phases above are the ones shown in official footage, named by their on-screen name bars. Tells, punish windows and health thresholds are added only once the retail fight has been checked; we do not invent them from trailer cuts.
