Although Yang Zhen had received news before coming to the Western Region that without special means it would be impossible to enter the Seven Yin and Seven Yang Land of Yaochi Holy Land, he still wanted to have a look.
Anyway, he was now just waiting for a summons from Yaochi Holy Land, and had nothing particularly important to do. Yang Zhen, therefore, snuck around and inquired about the location of the Seven Yin and Seven Yang by himself, secretly heading towards the edge of that land with his mischievous cat.
On the way, the cat seemed a little absent-minded, staring at Yang Zhen and saying, "Kid, the Seven Yin and Seven Yang Land is extraordinary, it's said to be linked to the Nine Nether Purgatory. Don't mess around, you may lose your life in there if not careful."
Yang Zhen was taken aback and glanced around at the seemingly ordinary surroundings, asking, "Does the Nine Nether Purgatory really exist?"
