Mortal Shen Yuntang is willing to become a demon and take his heart blood to save his childhood sweetheart, the Immortal Lord Gu Qingshang. But for Bai Yueguang, he personally cut out the roots of her love and forced her to jump off the Immortal Execution Platform. Thousands of years later, she returned as the new Demon Lord, but he knelt before her and begged her to turn back. Love and hate are entangled in seven reincarnations, and the two are extremely pulled apart in the battle between immortals and demons. When she finally let go of everything and committed suicide, he realized that he had been crazy in love - it turned out that Bai Yueguang had been her from the beginning.
