The control center of the Eye of Blood Eye was an arc-shaped building made of crystals right below the bloody lake.
The dome of the building was made of the purest crystals through which one could see the lake water, which was as deep and red as wine, as well as the rune arrays that were emitting a mysterious glow in the lake.
When the Heaven's Origin Sector was studying how to install underwater rune arrays, the problem of the corrosion of the flowing water was never satisfactorily addressed.
However, in the Blood Demon Sector, the demon race had combined the studies of spiritual stripes, rune arrays, and biochemistry.
The demon race produced a type of special demon beast named 'rune beasts' through secret techniques. Most of the runes were carved on the cellular level and etched into the rune beast's body. Then, the rune beasts were released into the water.
