In the grand scheme of races, it does not represent the grand fate of individual creatures. In such trends, the extinction of life is quite normal.
For the entire Human Clan, it is a fortunate event.
Yet when it falls upon the head of a specific individual of the Human Clan, it is not the same. Some benefit, while others lose their lives.
Regardless of prosperity or decline, survival or death, Fu Xi observes with cold eyes, without any intent to intervene.
Even now, when the Human Clan is flourishing, such phenomena exist, just as they do in the current stable state of the Demon Clan.
There are even instances where Fu Xi personally slays them, extinguishing their Primordial Spirit and sending them into reincarnation, and these are not few.
Do not forget, whether in the Heavenly Court or among the Demon Clan, the authority that Fu Xi holds is that of legislation and enforcement, lacking neither temperament nor iron-handed methods.
