On the Wutian Continent, in Lingxue Sect, young Lin Mo grew up under Su Hanyi's protection. After eighteen years of care, he depended on her completely, calling her "Mother." But the revelation of his true origins turns his life upside down: Su Hanyi was the culprit who slaughtered the entire Lin family. The blood feud and the warmth of her upbringing tear his life apart in an instant.
To avenge his family, Lin Mo embarks on a path of arduous cultivation. He awakens a talent for both alchemy and martial arts, and the soul master Lingyun Zhenren guides him. His power advances at astonishing speed, and he grows from a young disciple into a Soul Transformation powerhouse who shakes the cultivation world. On the day he returns, he massacres Lingxue Sect and confronts Su Hanyi. Faced with the blade of the child she once raised, Su Hanyi offers no excuses and only asks to atone with her life. Remembering the eighteen years she raised him, Lin Mo does not kill her himself. Instead, he lets her take her own life to repay the blood debt.
After Su Hanyi's death, Lin Mo has no sense of triumph at having avenged his family, only endless sorrow. He builds her a coffin of cold jade and a tombstone of snow stone, burying her in the back hills of Xueying Peak, where they once spent time together. He spends the whole night at her grave recounting the tender memories that hatred had buried. For decades afterward, Lin Mo protects the Peach Blossom Realm and secures peace for the world. His Dao heart grows ever clearer, and he eventually ascends to immortality, yet he can never completely erase Su Hanyi's mark from his heart.
This feud, spanning half a lifetime, ultimately leaves its regrets in the river of time. The hatred was real, and so was the kindness. Revenge does not bring release; its end is understanding the deep affection and helplessness hidden behind silence.
