After her elder sister left, Yi Xin whom she told to explain then explained everything to Qin Tian and Lan Yueli.
Not only did she explain about the mountain cave, she also explained about Yi Shi, and why Yi Xi said that he didn't need to think of that man as part of the Yi clan.
Mountain cave? It was the place under Mount Alasta.
As the place with the highest concentration of spiritual energy in the world, this mountain where the Wind and Rain sect was located naturally had its own magical place.
It is said that this mountain constantly refines the spiritual energy that envelops it and then collects it deep beneath the mountain, which is then called a mountain cave by the Wind and Rain sect people.
Once every few years, the amount of spiritual energy that Mount Alasta refines will reach its limit.
