Heart of Watatsumi mission guide - Genshin Impact - all puzzle solutions

To begin this quest, you need to complete the other four sections of the Watatsumi quest, then return to the Sangonomiya Shrine and talk to Tsuyuko. When she learns that you have the four pearls you will need to open the gate to the Heart of Watatsumi, she will direct you to the entrance.

Following the waypoint, then interact with the blue energy wall with the fish symbol on it to break the seal. Offer the four pearls and then go inside. Before jumping inside, assign numerical values ​​to the four puzzles, as you need to complete them in order.

• 1 - directly in front of you
• 2 - left
• 3 - on the right
• 4 - behind the central platform

Move to each section in order. The first three are all the same. Rotate the fish statues so they face inward, then take out the Hydro Mimics that spawn and interact with the puzzle's main pillar. When you get to the last one behind the central dais, interact with the pillar first, then line up the fish.

Three waves of enemies will spawn at this time, so be prepared for some battle. When you take out the last one, a cutscene will play showing hydroelectricity gathering in the huge pearl at the top of the cave. Get the key to the abyss and talk to Tasyuko again to complete the mission.
