The demon king Ni Lun was annihilated leaving the demon clan in tatters as they escape into the mortal realm. Chong Zi is pure and kind, yet she is the daughter of Ni Lun. After being saved by the immortal Chu Bu Fu, she becomes determined to cultivate at Nanhua but is turned away as it has been foretold that she will become a demon.
At this time, the venerable Luo Yin Fan surprisingly accepts Chong Zi as his only disciple. Chong Zi is very reliant on Luo Yin Fan and wishes for nothing more than to be by his side. In turn, Luo Yin Fan promises to protect her. A conspiracy leads to Chong Zi's imprisonment and Luo Yin Fan is unable to do anything to help, leading to her death for the sake of peace.
In her second life, Chong Zi comes to Nanhua again. Luo Yin Fan recognizes her in one glance. In order to protect her, he seals the evil miasma within her and keeps her close, thus continuing their relationship as master and disciple. However, there is no escape from the wheel of fate. Chong Zi once again becomes the target of a multitude of arrows. In a fit of rage, she embraces her demonic side and reaches the point of no return.
Fate has played a cruel joke on the star-crossed lovers - one is the venerable master who carries the world on his shoulders while the other has the blood of the demon clan flowing in her veins. They helplessly fell in love, helplessly turned against each other, yet they still cannot break free from their feelings. Can their love shake the rules of heaven and earth?
