"It's like this..." Li Wenxi explained to her briefly.
"Ah... There's actually such a magical place?" Lou Fei'Er was surprised, then her eyes shifted, "Wait... So... If you want the Chang Yin Family to return to their human bodies, wouldn't it require... human flesh and the special parts of their bodies?"
Logically speaking, that's indeed the case.
Especially since the special energy in the Chang Yin Family's bodies is the same as the energy in the altar.
Therefore, the monsters commanded people to create mysterious sounds to tell the Chang Yin Family that there's an altar on the surface, and through sacrifice, they could return to human form.
Thus, the Chang Yin Family left Xu Xin after coming to the surface.
Xu Xin later found traces of the Chang Yin Family's sacrifices at the altar.
