Chu Feng, who traveled through time and became a handyman of the Xuanjian Sect, was sent to die on the battlefield by his sect, but accidentally contracted Yan Li, the demon empress. After going through several difficulties, the two began to use each other and gradually became honest with each other. Chu Feng relied on the demon clan skills and weapon refining secrets taught by Yan Li to counterattack all the way and grew into a strong immortal cultivator spanning both body and law. With Chu Feng's help, Yan Li gradually regained her strength and uncovered the truth about the destruction of the race and the imprisonment of her relatives.
