How to find another way to enter the central area in Genshin Impact – Dune-Entombed Fecundity

Dune Entombed Fecundity: Part I is a Genshin Impact World Quest and is the third part of The Dirge of Bilqis quest chain. You'll unlock it immediately after completing the following prerequisites:

• Wisdom Has Built Her House, She Has Hewn Out Her Seven Pillars
• The Temple Where Sand Flows Like Tears

One of the objectives of this quest is to "Find another way to enter the central area." You must solve a series of puzzles underneath the Qusayr Al-Inkhida' to adjust the mechanisms and reveal the entrance to your destination. Follow the walkthrough below for a detailed breakdown of how to complete this segment.

How to solve the device and cell puzzles in the Dune-Entombed Fecundity Part I World Quest in Genshin Impact

Start by using the Four-Leaf Sigils to get to the other side of the room safely. Interact with the device circled in the image above to Rotate Valve once. Doing so will unlock a nearby mechanism.

Turn right to find the mechanism in front of the door. Interact with it to open the door and enter the room. Follow the path until you reach a clearing with Primal Constructs and a locked device. Defeat the Primal Constructs to get them out of the way.

Interact with the Control Unit to disperse the barrier, allowing you to exit the room. You'll immediately spot a device. Interact with it to Rotate Valve once. After that, enter the room again. The device inside will now be unlocked, allowing you to solve the puzzle.

Interact with the device once. This will prompt the junction behind it to expand, and the larger mechanism beside it will also activate.

Next, interact with the Everlight Cell in front of the large mechanism to rotate Cell once. This will prompt a Primal Beam to connect with another Cell on the other side of the room.

Enter the hallway on the other side of the room, where the arrow is pointing above. You'll spot a glowing spot on a decorated platform. Interact with it to activate the elevator that will take you one floor down. Defeat the fungi so they don't disturb you while solving the puzzle.

Head further into the room—behind the giant mechanism. You'll find an Everlight Cell. Interact with it to rotate Cell once, forming a Primal Beam that connects to the loose Cell on the opposite end.

Next, go back to the other side of the room and do these steps in the exact order:

1. Interact with the device to Rotate the Valve, which will adjust the junction and turn on the giant mechanism to the left.
2. Once that's done, interact with the Everlight Cell to rotate the Cell once. It will form a Primal Beam with the loose Cell on the opposite side, prompting a cutscene of a door opening.
3. Interact with the device again to Rotate the Valve one more time.

Remember that you must interact with the mechanisms above in the exact order, or you won't be able to solve the puzzle.

If you did the steps above correctly, your room should look like the above. Enter through the coffin-shaped door on the right, as the opening on the left contains an invisible barrier. Then interact with the mechanism to open another door, which will take you to the central area.
