Demonic Cultivator: from Little Taoist Priest to Unbounded Supreme Being

Zhou Xuan was desperate and wanted to die... Unexpectedly, he traveled through time and became Zhou Xuan, an unknown person. Fortunately, I have a copy of "The Heart-Eating Grimoire of the Absolute Beginning". If I go, it will backfire by 50%? ? ? ! ! ! The teacher's family was poor and banditry caused disasters. Is the little Taoist cultivating demons or demons? ... Open the "Heart Devouring Grimoire of the Absolute Beginning". Taotie swallows the sky, Qi Qi controls evil spirits, and the ground is shattered... When he used the magic book to refine the third divine beast, the so-called noble family couldn't sit still. "Devil! Learn the forbidden arts, and everyone will be able to kill them!" But while they claimed to be doing justice for heaven, they secretly coveted Zhou Xuan's secret magic book. Joined forces with Western demons and monsters to infiltrate secretly, plunder and kill loose cultivators, and seize the 'Marrow of Pangu'. ... The world is declining, and people's hearts are not in trouble. The devil is actually cleaner than them. That being the case, why show mercy?
