A ball of green light emerged before the ancient tomb in the Yin Ridge Mountains, swiftly spreading into a green magic formation. Two figures flashed into view within it: Shen Luo and Nie Caizhu.
The moment they appeared, their expressions changed slightly.
As far as their eyes could see, the entire Yin Ridge Mountain was shrouded in dense white fog. The fog was extraordinarily cold; almost all the vegetation had frozen to death, and a layer of white frost coated the ground and rocks.

It was already one of the most baleful yin sites in the world. But the terrain naturally forms a prison, trapping ninety percent of the yin energy underground, with less than ten percent escaping outside.
