After interacting with the block and thus applying Ousia to your character, just head back to the front of the locked area. In order to solve the Elton Trench Pneumousia Relay Puzzle and thus unlock the entrance to the room, perform an Ousia-infused attack on the Pneumousia Relay on the left (which will be infused with Pneuma).

Once hit, the Relay will then become Balanced and the air barrier in front of the locked room will be unlocked (thus turning blue).

Once the entrance is unlocked, you will be able to enter and grab all the goodies inside it (including the Hydroculus) by simply crossing the air barrier. Don’t forget to also explore the room for a few always-good for enhancement lower-rate artifacts.
