The Four Serpent Houses
The Green Serpent House lock uses the Serpent Eye, Tongue, and Fang to open a passage to Mirage Estate. The White Serpent House gate is a separate lock opened with the complete Loong Emblem.
Where the Houses Are
Green Serpent House stands in Pangzhen’s back streets and specializes in reproducing secret medicines of the Wulin. See Green Serpent House.
Red Serpent House lies north of the long bridge in Crimson Forest, where its keepers study medicine and Esoteric Arts together.
Black Serpent House is in the western corner of the Village of Lu and specializes in antidotes.
White Serpent House sits on an island in eastern Meigu Lake. It has stopped dispensing medicine.
Two Different Locks
The serpent-head mechanism in Green Serpent House takes three pieces: the Serpent Eye, Tongue, and Fang. The pieces were moved among the other Serpent Houses; the Red Serpent Tongue is specifically placed in Red Serpent House.
Fit the Eye, Tongue, and Fang into the Green House mechanism to open its hidden passage to Mirage Estate.
The White Serpent House door uses a different key: the complete Loong Emblem, formed by joining its Yin and Yang pieces. The emblem does not replace the three serpent parts.
Achievement
Solving the serpent-head lock in Green Serpent House unlocks A World Gone Hollow.
