In ancient times, the Mysterious Yellow Book of Fate shattered into nine fragments that scattered across the Three Realms. Whoever possessed a fragment could alter destiny and glimpse the secrets of heaven, sparking a thousand-year struggle among the human immortal sects, the Qingqiu Fox Clan, the East Sea Dragon Clan, the Southern Dark Phoenix Clan, and other forces. The young Su Yan awakens the Eye of Defiance against Fate because he bears the mark of a Fate Calamity. As he investigates his origins, he becomes bound by fate to Bai Ruoli, the saintess of the Qingqiu Fox Clan; Ao Qianjue, the young lord of the Dragon Clan; and Feng Qiwu, the last survivor of the Phoenix Clan. The four join forces and set out to gather the fragments of the Book of Fate.
Along the way, Su Yan discovers that his biological father is none other than the leader of the Xuantian Sect, who seeks to control the Three Realms. As the Host of the Fate Calamity, Su Yan must choose between sacrificing his beloved to repair the Book of Fate and destroying it, taking himself down with it. Bai Ruoli turns demonic to save her elder brother, her black hair turning completely white. After betraying the others under the influence of a soul-controlling parasite, Ao Qianjue sacrifices his dragon soul to atone. Feng Qiwu burns through her Phoenix bloodline to protect Su Yan. One after another, they fall or sink into a deep sleep for his sake. After being drawn into the Blood Sea of the Netherworld, Su Yan learns that the Book of Fate was shattered as a trial set by the Heavenly Dao, and that the flaw in its laws can only be mended with love.
In the end, Su Yan uses the emotional bonds shared by the four of them to reforge the Book of Fate, but loses his powers and withdraws from the world. Ten years later, in the peach blossom groves of Qingqiu, he reunites with his reborn beloved and their children. Yet the Chaos Demon God's prophecy, "The Fate Calamity will never end," plants a new seed of intrigue in this tale of love and hatred spanning the immortal, demon, and human realms. Blending mythological secrets, fantasy battles, and a tragic romance spanning three lifetimes, the story follows Su Yan's emotional choices to explore the timeless themes of love and sacrifice, betrayal and redemption. Its brisk pacing, vivid imagery, suspense, and emotional intensity make for a gripping read.
