The story takes place in the Hall of Reincarnation in the “Xuanhuang Completed Realm.” The protagonist, Yan Liangyi, is a fifty-one-year-old reincarnation records clerk with gray at his temples. He spends each day organizing records of all beings’ reincarnations, yet his own file is encrypted, leaving him unaware of his past life. When an anomaly occurs in the “Reincarnation Tide,” he is forced to come into contact with the “Calamity-Proof Pearl” in his mortal body. He unexpectedly awakens the “Ten Thousand Calamities Reincarnation Eye,” which lets him glimpse fragments of the past-life karma of all things. He also discovers that he bears the “Taotie Devours Heaven Bloodline,” capable of devouring and refining the laws of the universe. From then on, he embarks on a unique path of cultivation, starting over in middle age with “Awakening to One’s Nature.” He meets Youquan, a Netherworld ferryman who is steadfast in his duties yet troubled within, as well as a mysterious rogue cultivator known as the Red Thread Broker, who harbors an inexplicably deep hostility toward him and excels at manipulating fate. As Yan Liangyi cultivates the “Ten Thousand Laws Returning to One Sword Scripture” and comprehends the “Five Elements Cycle of Creation and Destruction Blade” and the “Dark Nether Ice Soul Curse,” he is gradually swept into a maelstrom. The Netherworld reincarnation administrator, the Judge, regards him as an anomaly that disrupts the balance and swears to erase him. Meanwhile, the Red Thread Broker is revealed to be the reincarnation of the Matchmaker God, whose important romantic bond was severed by Yan Liangyi in a previous life and who now obstructs him at every turn. As Yan Liangyi seeks the truth of his past life, reconciles the conflict between life, death, and creation, and repairs the “disharmony in his Dao foundation” caused by his bloodline and pupil art, he ultimately grasps the true meaning of “unity between heaven and humanity.” It does not mean replacing the Heavenly Dao, but becoming part of the universe’s healthy cycle. Between balance and creation, he finds his own “ultimate destination on the Great Dao.”
