Su Qingci is the only female sect leader in the Xuanling Sect's hundred-year history. Compassionate by nature, she is betrayed by the senior brother she trusts most and poisoned with a deadly toxin, leaving her on the verge of death.
No one knows that the boy she casually saved will grow into Mo Linyuan, the demon clan's young lord, renowned throughout the Three Realms.
Mo Linyuan gives up the honor of becoming the Demon Venerable just to bring her back to the Demon Palace and devote everything to her alone.
Everyone says immortals and demons are natural enemies, as incompatible as fire and water. Su Qingci, however, believes that connection comes from the heart, not one's kind.
A misunderstanding separates them across the world. Mo Linyuan searches frantically through the Three Realms, just for one chance to see her again.
On the day they reunite, Mo Linyuan is trapped in a desperate situation. Su Qingci descends from the heavens, sword in hand, willing to stand against the whole world for him.
From then on, they walk side by side, two powerful forces ruling together, never to be parted again.
