Read the Furnace Dungeon Map and inspect the Main Gate, Side Gate and Building. Cross the rooftops toward the eastern room and listen to the soldiers' conversation. Stay out of sight while the officers leave, then defeat the two guards at the locked gate.

Climb to the upper floor and use Celestial Seize (opens in a new tab) through the window on the Deputy Captain. Return with the Furnace - Dungeon Key, unlock the gate and take the lift down.

Enter the far-right cell and speak with the sisters. After they release you, accompany them along the corridor. Read On the God of Money with Little Fu, open the Large Chest with Little Shou and examine Burned Paper with Little Lu.

Inspect the candle beside the shelves. Help the sisters climb onto your shoulders and move left when Little Shou directs you. After the stack falls, inspect the vase still standing with the loong symbol. It operates the revolving shelf.

Pass through the shelf and follow the corridor to the next door. Stand on the slab directly in front of it to open it. Continue toward Yingying's voice; the sisters rejoin you after the following scene.
