Green Serpent House.

Green Serpent House is a big residence hung with green banners, found in the west of Pangzhen. Reaching it requires beating Xie Qiudong and then moving along the street. The bell sits right outside the entrance. Within, the player can improve medicine, obtain a story item and gather several collectibles close by. Far later in the game, a sealed door in the rear serves as the passage to Mirage Estate.

Within the house

Step inside and speak with Xie Huichun to obtain the Green Serpent Brew. This medicine wipes out all status effects, then keeps them away while your HP recovers. Healer's memories are also spent in this same building to improve your medicine.

Upstairs, a tiny chamber holds Serpent Gall: Green, which you hold onto for the later quest Four Serpent Houses. Hop out of that chamber's window and a Memory Flower sits dead ahead.

Pickups near the bell

1. Memory Flower: face away from the bell, grapple up to the roof and ascend the ladder. The flower is straight ahead.
2. Thunderward (accessory): go into the building to the bell's left. The chest sits at the far end of the room.
3. Sha-Chi Fragment: starting at the Thunderward chest, climb the stairs and walk along the balcony until it ends.
4. Memory Flower: exit that building via its side door, and you will find the flower next to the stairs.

Furnace and courtyard

Starting on the roof where the Memory Flower sits, step into the cave and follow the trail to its far end, which opens into a courtyard with a blacksmith's furnace. Kill every enemy there to get a Blackstone Fragment. Then face back and use the furnace to obtain Bronze Essence, which is used for tempering. Apply it to the the Tianxuan Bronze Sword and go back to Daoist Bi Di near Myst's Tavern Bell, and the Kuye Temple Sutra is your payment.

Bridge and locked door

Face away from the bell, walk over the bridge, take the stairs up and open the door on your left. It belongs to the Backstreet Courtyard section. Choosing "Leave him alone" as the Ledger of Atonement tale wraps up means skipping the Bai Xue tale, and this section's Memory Flowers then become permanently unobtainable. To stay safe, select the other answer, "This won't absolve you of your sins", when that moment comes.

Door to Mirage Estate (late game)

Under the main quest Four Serpent Houses, you travel to other regions and retrieve the White Serpent Eye, Black Serpent Fang and Red Serpent Tongue from the White, Black and Red Serpent House zones. Come back with the three and the sealed door at the house's rear unlocks, giving entry to Mirage Estate.

Arriving

Beat Xie Qiudong, the Divine Healer, in the Well of Wei Sanchuan and keep moving through the area until the green building comes into view. The Green Serpent House Bell stands right outside it.

Continuing from here

Descending the whole staircase from the side-door Memory Flower brings you to You Loong, Leader of the Blackwater Crew. Beating him yields the You Loong's Deluge Phantom Edge. Past his arena, a timber walkway reaches a Banyan Tree challenge location, where enemy waves come first and then Master Bi Yuan of the Tianxuan Sect fights you again. To head for the Lion Dance Hall, return to the stairs and enter the alley to the left.
