Ancestor Xuan Yue stroked his beard for a long time before speaking, "This matter is highly strange. On the Immortal Path of cultivation, each person's Dao Foundation is different, which leads to different Mana being cultivated. Even the Devouring Techniques from the Evil Sects and Demon Sects that have been passed down through the ages, fundamentally speaking, only absorb some blood energy. The more skillful techniques can devour a bit of the Primordial Spirit, but has there ever been one that could completely devour an opponent's blood energy and Primordial Spirit?
Some descendants of Spiritual Items and Divine Beasts also devour and fight among each other, but that's merely akin to consuming an extremely nourishing substance. If True Dragon Descendants could inherit and fully consume each other across generations and spaces, then wouldn't the one at the end be able to devour you all as well? What if the True Dragon isn't dead and is simply waiting at the end?"
