A river of blood stretching ten thousand miles cascaded down from Silver Plain Mountain. Countless ferocious Demon Soul Generals crawled out of the river and slaughtered in every direction.
Shen Mo did not think much of ordinary Heavenly Demons and could not be bothered wasting mana to refine them. He simply had the Demon Soul Generals kill them. Only Heavenly Demons with decent strength and potential were forcibly dragged into the river of blood and refined into Demon Soul Generals... Even so, Shen Mo could barely keep up by using his mana to connect with the spiritual energy of heaven and earth. The number of Demon Soul Generals within the banner swelled by hundreds of thousands each day.
He was not worried that seventh-rank Great Heavenly Demons, comparable to True Immortals, would come knocking over this matter.
Quite a few True Immortal figures had gathered in western Dongjie Continent. They slaughtered Heavenly Demons far more ruthlessly than Shen Mo did; a single spell could eradicate a hundred thousand, even a million Heavenly Demons. If seventh-rank Great Heavenly Demons wanted to cause trouble, they would seek those people out first.
Yet at this rate of slaughter, although the proportion of high-rank Heavenly Demons had fallen considerably, first- and second-rank Heavenly Demons only increased rather than decreased. They had even begun spreading into other regions of Dongjie Continent.
To explain this, one had to begin with how Heavenly Demons were born.
The methods by which living beings reproduced in the world came in every conceivable variety. Some, like humans, produced offspring through the union of yin and yang; some, like Flower Fairies, grew from a Mother Tree; some, like the Longevity Clan, split themselves apart; and some, like the Ten Thousand Insect Evil Corpses, underwent transformation through the gathering of countless individuals.
