At first, the noises, vibrations, and additional light would be transformed into heat when the runes on the dome were running.
Then, the four cooling towers would carry the heat away.
What flowed in the interconnected tubes was all cooling liquid. When it passed the cooling tower, the cooling liquid would absorb tremendous heat and be vaporized into steam, which was then transmitted deeper underground through other tubes.
Li Yao estimated that an underground river would be down there to transform the steam into cooling liquid for recycle purposes again.
Through such a way of circulation, the redundant heat was consumed to the largest extent, and the stability of the Eye of Blood Demon above would be ensured.
However, what if the cooling towers were all blown up?
