In ancient times, it was divided into four realms - Demonic Realm - Heavenly Realm - Spiritual Realm - Mortal Realm
Su Mianmian, a butterfly demon with low magic power in the spiritual world, accidentally bound to the three-dimensional system and went to the demon world to conquer the Demon Lord Mo Yunli. Su Mianmian went to redeem Mo Junli as a maid of the Demon Palace. However, when the favorability of the conquering task reached 100%, the Demon Lord learned everything and understood that Su Mianmian only loved him for the task. His favorability plummeted instantly and imprisoned Su Mianmian in the Demon Palace. The mission could not be completed, and Su Mianmian was wiped out by the system. The Demon Lord tried his best to resurrect her, but after rebirth, Su Mianmian lost her memory. Mo Yunli regretted it so much that he surrendered. Heaven took this opportunity to seal Mo Yunli in the Nine-Storey Pagoda. He learned the truth from his close friends and restored his memory. In order to save his former lover, he voluntarily entered the Abyss of Souls and helped Mo Yunli lift the seal at the cost of his soul.
