Others cultivate immortality relying on talent, sects, and chance encounters, while Su Qinghe has practiced for ten years only to master a neglected rain-making technique, mocked by villagers as a "useless immortal master." Until a bizarre heavenly thunder descends, he accidentally uncovers a startling secret behind an old, broken bronze mirror—the chaotic inheritance that has slumbered for ages has actually chosen him! The sealed peerless spiritual root, the overwhelming karma that destroyed ancient sects, and the supreme treasures lost in the world, all mysteries surface once again because of his appearance. When others are desperately searching for immortal affinity, Su Qinghe has quietly taken control of a mysterious cave heaven, possessing the power to reverse the years. Only, there is still much he does not know!
