In mythology, King Yan is a deity of the underworld, responsible for managing the order of life and death reincarnation. "Resurrection from the dead" is undoubtedly a violation of the order of life and death reincarnation, and if there really is a divine entity managing death in this world, it is very likely that they would not ignore such a "resurrector" like Mazao.
And in the memories accompanied by Yinyue's "illusion", Luo Mountain seemed to stem from a place called "Naraku". Naraku—in Buddhism, it is another name for hell. It's as if it is said, at some point in history, Luo Mountain truly existed in the afterlife world. Combining titles such as Impermanence, Lu Youxun, ghost soldiers (the old title for agents), and the name Luo Mountain itself, the underworld feel of Luo Mountain is so extensive that one cannot help but think more about it.
