On the first day Lu Zhao transmigrates to a world of cultivation, he is forced into a clash between the righteous and demonic factions. Su Li, his childhood sweetheart whom he saved, bears a lotus mark from the same source as the Heavenly Demon Mirror. And every time he takes a fatal blow for someone else, the dormant remnant soul of the Demon Venerable within him grows more restless. When his ability to imitate spirals out of control and consumes his close friend’s cultivation, and the reflection in the mirror gradually replaces his own consciousness, he finally glimpses the blood-soaked truth: the so-called Heavenly Dao is nothing but a lie woven by a Divine Venerable to conceal the crime of murdering his wife.
