Their situation is worse than what happened between Mo Baojun and Shen Siwang.
Xia Jieye's soul isn't a complete one like his uncle, Mo Baojun when he died. During his first death as a Sovereign God. An unknown entity as strong as the Origin had tried to take away his soul. The Origin didn't agree and the chaos caused his soul core to be separated from himself while the rest of the soul had entered reincarnation.
This reincarnation is the one called Ye Xiajie. He had no memories of himself as the God of Void and was born as someone from the hated Ye Gui Race. He is an outcast that left his race with his younger brother. But even if a Yue Gui left the race one could never escape their fate as one. They still need to succumb to their life mission and this man's life mission is to assassinate the youngest descendant of the Mo Clan, Hei Anjing.
