Upon arriving near the demon cavern, they saw a gigantic "tree" within the depths of the black mist. Large tumors grew all over the tree, and the branches Lu Yu saw were extensions formed by these tumors.
Each branch represented a demon manufacturing factory. The thousand-meter-high giant tree was covered with hundreds of branches of various sizes.
Hundreds of demon manufacturing factories worked simultaneously, with new demons emerging from the cavern every second. That's how the endless stream of demon folk came to be.
At the top of the giant tree, they saw the true enemy of this war.
"What? Zhou Chisheng has turned into a demon?" the Dean of Beifeng Academy exclaimed incredulously.
Lu Jingfeng said helplessly, "Vice Dean Zhou suppressed the Demon General for too long. It was inevitable that during the time of the dark sun's arrival, he would be corrupted by demonic qi and transformed into a demon."
