Su Wang, a young outer disciple of the Xuanyuan Sect, is mocked for having a crippled meridian spiritual root. During a rainy-day martial arts demonstration, he unexpectedly awakens the wondrous art of Heavenly Derivation. An ancient jade pendant in his palm splits open, revealing a fragment of “Heavenly Secrets,” which is mysteriously connected to the bloody case in which his mother lost her life in the Scripture Pavilion twenty years ago. When he uses defiant Dao patterns to deduce and dismantle the inner disciples’ spirit weapons, the bronze doors of the Tianji Hall atop the main peak swing open with a crash. In the remnants of a star chart left by his mother, an apocalyptic era-name from the Nine Domains of Tianyuan glows blood-red. And the newly awakened Heavenly Derivation eye in his pupil can see the hidden “fractures of fate” deep within everyone’s spiritual roots. As a wave of spiritual-root awakenings sweeps across the Nine Domains and the various sects vie for rare spiritual physiques, Su Wang faces probing tests from the sect’s elders and pursuit by mysterious assassins. He gradually uncovers the secret history of god-slaying behind the Xuanyuan Sect’s thousand-year legacy. The whispers of the remnant soul inside his pendant will ultimately lead him down a defiant path: “With my blood, I will rewrite the Heavenly Dao.”
