Part of the reason the Ancient Demon King did not reject the blood of Ancient Demons was that they were of the same bloodline. Nonetheless, the proportion of this reason was very small.
Unlike humans, there were tens of thousands of types of Ancient Demons. When the countless blood essences merged, it was already difficult to tell the qualities. The main reason the Demon King could withstand it was its body. Every Demon King must have a strong body.
This was a condition that humans, such as the Nine-sworded Ruler, did not have.
If the Nine-sworded Ruler had the physique of an Ancient Demon, he would not have wasted his time slaughtering more than 20 small worlds.

In the words of the ancient style, he was inhuman.
