The Primordial Mythical Beast, born when the heavens and earth first opened, absorbed the chaotic air, and it is something even immortals do not casually provoke. The region of Buliang Mountain is peculiar, with three years of summer followed by three years of winter. As the winter season nears its third year, the Primordial Mythical Beast goes hunting and hibernates, so Qingwu probably took advantage of this opportunity to place the Glassy Bottle there.
This means that once the Primordial Mythical Beast returns to its lair, it will be several years before they can safely retrieve the Glassy Bottle. Qingwu's choice of this location is rather malicious. No wonder A'Li was cursing him earlier. They can only hope the Primordial Mythical Beast hasn't returned yet.
When they reached the vicinity of Buliang Mountain, they saw a group of enormous Primordial Mythical Beasts heading toward Bu Zhou Mountain. Nanli's eyes nearly darkened.
