"In this way, as long as we hold back and eliminate the demon beasts rushing out from the Great Moon Mountain bit by bit, the Beast Tide will end."
Following Taoist Xiuyu's explanation, Su Yu finally understood. The Beast Tide didn't just appear like a single wave, nor did it retreat before launching another attack.
Instead, it was more like a sea wave: the demon beasts from different areas of the Great Moon Mountain gathered and charged out wave after wave in an irregular and unpredictable manner.
It only ended when there were no more demon beasts left to form a Beast Tide.
This situation was not only a grudge held by the Demon Clan against humans for encroaching on their territories, but also a method used by the Great Moon Mountain to control their overpopulated demon beast population after certain periods.
