**Story Overview**:
Lu Zhao, a poor-born youth carrying the Profound Heaven Sword Bone, is drawn into a thousand-year conspiracy in the cultivation world after an anomaly appears during his spiritual aptitude test. Lu Yuanshan, an elder of the herb garden, uses a bloodline restriction to control the cultivation clans, intending to resurrect an ancient Heavenly Demon through Lu Zhao's body. While fleeing, Lu Zhao is aided by Su Li, the remnant soul of a merfolk, and Luo Chuan, a white-deer Confucian cultivator. After enduring trials across the Thirty-Three Heavens, he uncovers the truth: the Lu family's ancestor betrayed the merfolk pact. When the Tideborn Sword emerges, the Land of Fallen Stars appears. Lu Zhao uses the Profound Heaven Jade to break the seal of Guixu, only to discover that his grandfather, Lu Yuanshan, has implanted the Heavenly Demon's bones into his own body. On the night the blood moon becomes whole again, a bronze warship carries one hundred thousand rebel armors. Sword in hand, the youth shatters the Thirty-Three Heavens and confronts his bloodline's fate atop the Sea of Tears: slay the Heavenly Demon, or become a new demon? The final battle to defy the will of heaven begins as the tides roar.
