In ancient times, the Heavenly Emperor opened the Gate of Firmament, connecting the Heavens and Earth. Mortals could ascend to the Gate to obtain divine power in order to assist in the search for the Emperor's missing daughter. Unscrupulous individuals took advantage of the Emperor's gesture, and caused the mortal world to descend into chaos. The lives of the common folk were filled with anxiety and weariness. The god Fuxi and the goddess Nüwa took pity on the people, and along with Zhuanxu, convinced the Queen of Huaxu (華胥之主, based on Lady Huaxu 華胥氏) to close the Gate forcibly with great sacrifice. After this, no one could reach the Heavens through the Gate, and no god could go to the mortal world; thus came about the Isolation of the Heavens and Earth (Jueditiantong 絕地天通). Time passed, and the mortal realm suffered due to disasters and endless conflicts over claims to rule, embroiled in political instability and riotous events. At this time of unrest and warfare, a Heavenly entity descends, adding to the unsolved mysteries of the troubled world.
