Su Qinghan, the emotionless Immortal Venerable of Kunlun, found the orphan Shen Xingyao in the mortal world and took her as her only personal disciple.
The two spent their days and nights together in Qinghan Hall. Her master personally taught her swordsmanship and cultivation, and secretly shielded her from trouble at the sect. The girl made osmanthus cakes with her own hands, carefully hiding the love in her heart. But Su Qinghan clung to the emotionless path and could not tell the difference between protecting someone and falling for them. At the birthday banquet, Shen Xingyao confessed her love while drunk, only to be sternly reprimanded. The once-close master and disciple were left worlds apart.
When the demon world invaded, Su Qinghan was struck by a seductive bone poison that specifically countered the emotionless path. Fearing she would lose control and hurt her disciple when the poison took effect, she publicly left with her senior sister to enter seclusion. Shen Xingyao saw this and thought she had been abandoned for good. Heartbroken, she left behind a letter and set off alone into the martial world.
After reading the farewell letter, Su Qinghan's Dao heart shattered. She abandoned the emotionless path to cultivate the carefree way, spent five years braving wind and snow across the four corners of the world, and desperately searched for the disciple she had hurt so deeply.
In the Southern Frontier, Shen Xingyao was ambushed by demon assassins and stepped forward to take a poisoned blade. The two fell into a secluded valley. Trapped at the bottom, the former master and disciple were forced to spend their days and nights together. Old dreams and nightmares haunted them again and again, and the secrets of the past gradually came to light.
Back in Kunlun, the two fought side by side in a bloody battle against the Demon Lord. Faced with the shackles of convention and their old master-disciple relationship, Su Qinghan set aside her status as an Immortal Venerable. Passionate and forceful, Shen Xingyao took the initiative at every turn and held on to the love they had struggled with for years.
Ten years of love and resentment, an inferno that burned away the old moon, until the moon in the ashes finally found its heart. After overcoming misunderstandings and life-and-death trials, the former master and disciple broke free of their constraints. Despite their many scars, they chose each other and stayed together year after year.
