As the darkness dissipated in Yun Jhin's vision he could finally see the underwater civilization and how advanced it was.
As Yun Jhin's gaze traveled through the water he could see houses of different sizes which were made from though corals which were held together by dead marine life bones and different materials that he couldn't identify immediately.
While he took a better look he realized that the buildings were glued together by some green paste that he recognized as draconic plankton.
The draconic plankton was very useful to temper the laws in the body of the God Realm experts at the lower stages but it was rather expensive and hard to find, Yun Jhin had some stashes of draconic plankton back at the sect and when he came back from this conquering expedition he wanted to use them, as in the God Realm there were levels for the stages, Yun Jhin was currently in the middle to later stages of the 1st stair of the God Realm.
