Born with "nine incomplete spiritual roots," Yang Yu is regarded as an outcast of the Heavenly Dao, a good-for-nothing cultivator who suffers endless bullying and is not expected to live past twenty. Then, at the brink of despair, the "Reverse Cang Pearl" lying dormant in his dantian quietly awakens. The pearl can devour the "aura of vicissitude" born from the rise and fall of all things under heaven, then feed that power back to him, repairing the spiritual roots thought to be his curse! From that moment on, a rugged path opens beneath his feet: proving the Dao through vicissitudes and defying heaven against all odds. From the mortal realm to the Immortal Realm, the Spirit Realm, and the Demon Realm... He traverses the nine realms, devouring countless ages of vicissitude. When he stands at the summit with all nine spiritual roots perfected, he discovers that the so-called "taboo of the Heavenly Dao" is itself the greatest conspiracy. This time, he will reverse not only his own fate, but also the ninefold vicissitudes that have shrouded the ages!
