Haitin caught Aksai's confusion and offered a quick explanation.
"It's because of the beast tides," Haitin began.
"Every hundred or so years, the Great Shiju River recedes to dangerous levels, allowing the demon beasts from the Duya Forest to cross into our lands. The Wild Devil Lands is the first place that gets hit. If we don't deal with it there, the beasts will sweep across the entire subcontinent, causing massive losses to mortals, cultivators, and resources alike."
Aksai was initially taken aback, but he had indeed heard stories about the beast tides of the past. He had also read some of the records.
According to Dadangar's history, the Great Shiju River acted as a natural dividing line between the cultivation civilization and the Duya Forest, also known as the Eternal Beast Dynasty, the domain of demon beasts.
