Demon race was indeed demon race.
In the two great wars of immortals and demons, the exuberant vitality of the demon race had left a deep impression on human cultivators. Cutting off the head and destroying the heart did not cause fatal injuries. Even injuries that touched the depths of their soul could not really kill them.

Wang Lu and the others also didn't want the two girls' lives, because this was their first spoils of war in the demon world. Moreover, to uncover the truth hidden in the demon world, they needed some locals for questioning.
