Su Li, the second daughter of the Qingyun Sword Sect, is actually Bai Li, the Primordial High God. Ten years ago, she sacrificed herself in place of her elder sister and plunged into the Abyss of No Return. Upon returning, she is betrayed and has her first-grade spiritual vein forcibly removed, while her parents, including Xue Zhonghua, side with those who harmed her. In her despair, Su Li awakens her divine nature, and the Demon Lord Cang Ye protects her every step of the way. The Su family conspires with the false god Wuji in an attempt to seize sole control of the Three Realms. In the end, their conspiracy is exposed, the Su family's crimes are punished, the false god is overthrown, and new rules are established to unite the immortal and demonic realms without boundaries. Together with Cang Ye, Su Li safeguards peace between the two realms.
