Prior to this, several Demon King Ancestors had no interest in the Ten Thousand Beasts Sect. But as the Vice Sect Leader of the Ten Thousand Beasts Sect mentioned that the true explanation of the Ten Thousand Beasts could be cultivated by demon beasts, their expressions suddenly froze.
Spells suitable for demon beasts are regrettably few, let alone cultivation techniques that can be practiced by demon beasts. At least in the Celestial Essence Ancient Country, they had never heard of any sect whose core cultivation technique was suitable for beasts to cultivate.
The true explanation of the Ten Thousand Beasts, which the Demon King Ancestors are aware of, is a cultivation technique that complements the Ten Thousand Beasts Sect's magical artifact, the Ten Thousand Beasts Circle.
Solely relying on the Ten Thousand Beasts Circle to subdue demon beasts has significant flaws. When encountering some extremely vicious and powerful demon beasts, it's easy to lose control.
