The Ancient City Key is a one-time quest item in Genshin Impact, introduced in Version 4.4 within the Chenyu Vale region of Liyue (near Chizhang Wall). It is obtained by solving a Jade Incense Cauldron puzzle and used to unlock a Millelith warehouse for rewards, including the "At the Construction of the Endless Wall" achievement (5 Primogems).
Step-by-Step Guide to Obtain the Ancient City Key
- Navigate to the Location: Teleport to the Statue of the Seven or waypoint east of Chizhang Wall (coordinates approximately at the ruins directly west of Yaodie Valley, east of Chizhang Wall). Enter the ruined tower/structure containing two Jade Incense Cauldrons in front of a locked gate.
- Solve the Jade Incense Cauldron Puzzle:
- Locate the floating Adeptal Energy orb (light ball) nearby.
- Position your character behind both cauldrons, aligning them so the orb's light beam ignites both simultaneously when activated (stand at a spot where the cauldrons are in a straight line between you and the orb).
- Interact with the orb to release the energy, lighting the cauldrons and unlocking the gate.
- Claim the Rewards: Open the Exquisite Chest inside the gate to receive the Ancient City Key and Chizhang Map (which provides a clue to the key's usage location).
How to Use the Ancient City Key
- Follow the Chizhang Map: From the Chizhang Wall teleport waypoint, head south/southwest to the ruins (southeast of Chizhang Wall, northwest of Mt. Lingmeng; marked as the "third ruins" on the map).
- Unlock the Warehouse:
- Enter the ruins through a broken window/opening.
- Approach the locked gate on the left (Millelith supply room).
- Use the Ancient City Key to open it.
