Chapter 4264: He hit the nail on the head.

"Taking in a disciple? Hmph, I'm afraid that you want our blood essence more, right?" Huangfu qingjue said coldly.

"Eh, you can tell?" This time, the two grey-robed elders were clearly surprised.

"It's just a nether body evil cultivation technique, what's so great about it? You self-destruct your own body and rely on devouring the blood essence of other cultivators to rebuild your body while absorbing their vital Qi at the same time. You actually dare to cultivate such an evil technique, is there really no one else in the heaven domain?" Huangfu qingjue shouted sternly.

"You're quite knowledgeable indeed. You actually know the secret of our netherworld body evil cultivation technique. " The two gray-robed elders licked their lips and looked at Huangfu qingjue and Ling Chuxi with even more admiration. They were like wild beasts in the wilderness who had seen a delicious feast covered in blood. Perhaps that was not admiration, but appetite.
