World view: The three realms are divided into three realms: immortals, humans, and demons. With the "Lock Immortal Abyss" as the boundary, immortals and demons have been in opposition since ancient times. The fairy world is respected by the "Lingxiao Palace" and believes in the order of heaven. Practitioners need to cut off the roots of love before they can ascend; the demon world lives in the "Burning Demon Realm", where strength is respected and lust is the nourishment of practice. The human world is a gap between two realms, with mortals and scattered descendants of immortals and demons. Hidden is the "Reincarnation Mirror", an ancient secret treasure that can break the balance of the three realms. It is rumored that it can reverse life and death, but it requires the most precious emotions as a sacrifice.
The core of sadomasochism: the shackles of identity of immortals and demons in different ways, the iron law of the immortal world that "love will lead to divine punishment", the sacrifices and misunderstandings that have to be made to protect each other, and the paradox of "love and redemption" caused by the mirror of reincarnation (saving one person may destroy the three realms).
