When a demonic cultivator massacres a city, Xie Cijing, senior sister of an immortal sect, pursues the enemy and saves Gu Ningshuang, who is still mortal.
An ethereal, aloof immortal maiden descends from the sky with sword in hand. In that fleeting, breathtaking moment, she is engraved in Gu Ningshuang's heart.
A spiritual pill given as a gift sets their immortal connection in motion.
Gu Ningshuang embarks on the path of cultivation and joins Xuanyin Sect, a branch of the Daoyi Immortal Sect. She devotes herself to cultivating, all for the day she can go to the immortal sect and become Xie Cijing's junior sister.
Over the next few years, Gu Ningshuang repeatedly displays her talent and makes rapid progress in cultivation. After distinguishing herself in a demon-subjugation mission, she finally gets her wish.
By then, she has reached the Golden Core stage, while Xie Cijing has already attained the Divine Transformation stage.
When they meet again at the immortal sect, Xie Cijing seems to have completely forgotten the mortal girl she once saved.
As they pass each other, Gu Ningshuang calls her senior sister, but Xie Cijing acts as if she hasn't heard and remains cold.
When ferocious beasts run amok, Xie Cijing is ordered to suppress them, and Gu Ningshuang goes with her.
Just as the seal is about to be completed, an unexpected change occurs. Xie Cijing is badly wounded, and she and Gu Ningshuang fall together into the mortal world.
Her senior sister, as lovely as the moon in the sky, takes the initiative and confesses her love. Gu Ningshuang falls into the net of love and cannot escape.
A year later, Xie Cijing regains her cultivation and leaves without a word.
When they meet again at the immortal sect, all the happiness they once shared seems to have been forgotten. There is nothing but coldness between them.
Gu Ningshuang clings to Xie Cijing, hoping for an answer, but never gets one.
Until one day, she accidentally glimpses the secrets of fate through a forbidden technique and learns that Xie Cijing is the chosen one, destined to cultivate the path of ruthless detachment. Gu Ningshuang is nothing but one of Xie Cijing's mortal trials.
Now that the trial is over, Gu Ningshuang means nothing to Xie Cijing.
Heartbroken, Gu Ningshuang stages her own death, leaves the immortal sect, and becomes a carefree rogue cultivator, turning her back on worldly affairs.
That same year, the senior sister of the immortal sect falls from the Dao into demonic cultivation and searches all across the Yunxuan Realm, determined to find one person's soul…
Happy ending. The early part focuses mainly on the plot.
