Yan Xiaosi said, "It smells good, but not as good as your little snakes, chickens, and flying fish!"
The Demon Lord instantly straightened his back. "Of course!"
Of course, his demon beasts' realm was higher than these spirit beasts!
Speaking of which, righteous cultivators could not eat food with demonic energy. At best, they could not subdue it. At worst, their cultivation would be corroded by demonic energy, but Yan Xiaosi did not have any such problems. She could even eat their souls.
However, with Yan Xiaosi's eating speed, the Demon (Spirit) Beasts and Demon (Spirit) Plants of the Immortal Demon Mountain and the Holy Peak Mountain would probably be wiped out before long. The mutant beasts and mutant plants outside probably could not satisfy Yan Xiaosi's appetite.
The best way to improve this stretched situation was to ascend and open a passageway to the higher realm.
