Genshin Impact Silent Seeker of Knowledge Sumeru Archon Quest Domain walkthrough

The Sumeru Archon Quest Chapter III: Act I - Through Mists of Smoke and Forests Dark is divided into multiple subquests, one of which is called the Silent Seeker of Knowledge. In this segment, you enter the cave to find an unconscious Hypasia, as well as a little fairy friend. After losing consciousness, you’ll be teleported into a quest Domain that you need to complete to progress. 
You can only complete this Domain once, so follow along to find out how to solve all the puzzles and loot all the Chests inside.

All puzzle solutions & Chest locations in the Genshin Impact Through Mists of Smoke and Forests Dark Sumeru Archon Quest Domain

First Primordial Rosin location

Upon entering the Domain, follow the path forward until you reach the clearing with giant plants and Bouncy Mushrooms. Defeat all the enemies in the area to loot a Common Chest. Use the Bouncy Mushrooms to climb the giant plant and reach the high-up areas. 
There are two rooms inside the cave. Enter the one the arrow is pointing to in the image above. Inside, turn left until you see the red room with enemies. Defeat all the enemies and loot the Common Chest.

After looting the Common Chest, approach the Sumeru Phase Gate to be teleported to the inside of a giant flower, where you’ll encounter a plant with an orange gem called the Primeval Rosin. Interact with the plant to pick up a Primeval Rosin, then follow the quest marker to the exit of the cave. It’s not possible to swim and climb to the exit due to the structure of the mushroom platform, so use the Four-Leaf Sigil to help you. 
Once outside, you’ll be back to the starting area. Glide toward the lilypad platform beside the cave you entered earlier to pick up a Common Chest reward.

Second Primordial Rosin location

Use the floating platform near the previous area to get closer to the lilypads at the back of the cave. Then you’ll spot a Four-Leaf Sigil—use it to propel you upward to the location of the second Primordial Rosin. Interact with the plant to loot.

Third Primordial Rosin location

Head to the last room in the cave and follow the path forward. You’ll be transported to an Inazuma estate. Keep following the path, and be on the lookout for a Common Chest after going down the stairs. After this segment, you’ll be transported to a small cave with the third Primordial Rosin. After looting it, the barrier blocking the exit will disperse, allowing you to return to the starting area.

Path to the upper level of tree hollow

From the location of the second Primordial Rosin, keep propelling yourself upward using Four-Leaf Sigils until you get to the top of the clearing with an orange structure, pictured above. Approach it until all three Primordial Rosins merge with the structure, then interact with it to Activate. You’ll be transported to another Inazuman estate.

There’s a rock image puzzle in the courtyard. Head to the glowing spot and adjust your camera angle until you form the illusion of the two rocks connecting, forming an image of a flower. Once that’s done, the door on the left will open. Enter it to step on an elevator, then wait to be transported to an area with a giant flower.

Go to the upper platform

This part is pretty tricky. You’ll immediately spot two Four-Leaf Sigils, but there’s one tucked away that will actually propel you upward. Head to the Four-Leaf Sigil at the edge of the room, then look up. You’ll find a third Four-Leaf Sigil in the air, by the edge of the giant flower petal. Use it to propel you upward and reach the upper platform. 
Here, you’ll meet a Hydro Abyss Herald and will engage in an unwinnable battle. Once that’s over, you’ll be teleported out of the Domain and back to the real world.
