This article will guide you on How to Solve the Salacia Plain Red Barrier Hydroculus Puzzle in Genshin Impact.
To locate the Hydroculus Puzzle, proceed to the Salacia Plain, which is located southeast of the Court of Fountaine.
When you get to the Hydroculus Puzzle location, go to the left side of the structure to look for a blue gem on the cliff and perhaps some Fontemer Aberrant Crabs or Fish nearby.
First, use your normal attack on nearby Fontemer Aberrant Crabs or Fish to get their power. Then go to the blue gem and use your E Ability on the blue gem. This generates a shockwave and activates the mechanism that propels the ball ahead.
You will now notice a golden ring behind you. Approach the ring and hit it to activate a current and this will make the orb go inside it.
Next, proceed to the broken bridge on the other side of the barrier. Here you will see that water is running through a golden ring in a downward direction and pushing the ball down. Attack the ring to alter the direction of the water flow, causing the orb to attach to the ring.
Finally, proceed to the Red Barrier to interact with both mechanisms. Once you’ve interacted with it, the barrier will turn blue and you will be able to enter.
