The Doctor's Hei Yu died before the eyes of the God of Void, and the culprit is none other than Archangel Michael, the God of the world they are in. It just so happened that Michael of this world is another soul fragment of Hunluan and has no direct connection with the God of Destruction except for the fact that their origins are the same.
Chaos is the energy that causes all disturbances and war in existence. It is also the source of all life. It can appear in the past and the future. However, it always exists in the present and is something that cannot be fully avoided. As long as there is conflict and difference in the world, chaos will always exist.
With a face devoid of all emotions, Archangel Michael nonchalantly pulled the heart he dug from the human doctor called Hei Yu. The corpse of the doctor falls in the embrace of the God of Void, who seemingly looks unexpectedly calm after that one shout from him.
