Ancient God of Origin's thoughts when his eyes met with the God of Destruction.
"These eyes... are v'ry similar to Luan''r on the day we hath asked that gent to killeth the w'rld consume'r. Doest that gent knoweth what we has't done?"
Translation: [These eyes... is very similar to Luan'er on the day we asked him to kill the World Eater. Does he know what we have done?]
The madness within Hei Anjing is more than what his deceased child, Hunluan, possessed after birth. It was because of this madness that Jiewei and he were terrified of their own descendants. The power of chaos can even affect ancient gods like them and make them mindless monsters that can only bring unrest.
That's what frightened them, and as new parents, they failed to become good parents to Hunluan and left him alone in the chaos to fend off on his own. This was Qiyuan and Jiewei's greatest regret and the deepest thorn in their hearts.
