The ancient divine beast Zhulong fell in the war between gods and demons a thousand years ago. Only a wisp of her remnant soul survived, drifting into the Demon Realm. It is said that once Zhulong cultivates into a god, she will be able to control the passage of day and night, the changing of the seasons, and the cycles of space and time, wielding boundless divine power.
The war between gods and demons a thousand years ago shattered the barriers between the Demon Realm and the human world, allowing countless vicious demons to escape into the human world and prey upon its people. The leader of these demons, Juling Xiu, sought to unite the Three Realms. To that end, he continually stirred up conflict between humans and demons, sending hordes of vicious demons into the human world. The human race refused to stand by while demons ran rampant and fought back with all their strength. To increase their own power, many cultivators used the pretext of hunting demons to extract demon cores for their own use by any means necessary.
When Xiao Muchen, the Fifth Prince of the human empire, was young, his mother was killed by a demon. He came to despise demons, and, as a member of the imperial family, embarked on the path of cultivation. He vowed to eradicate every demon under heaven and protect the peace of the human world. At just ten years old, his father sent him to the Demon Suppression Bureau to train, and he became a renowned human cultivator. Wherever demons appeared in Youqi City, he was sure to be there.
Meanwhile, half of Zhulong's remnant soul had taken on physical form, emerging beneath an old plum tree as snow fell thickly. The elderly demon elders knew the truth and had more or less guessed her identity. For the sake of stability in the Three Realms, they discussed the matter with several clan leaders and decided to send Ling Chuer, who had only just taken shape, to the human world to gain experience under the identity of the Demon Spirit Realm's Holy Maiden.
