Ten Thousand Demons Swallow the Sky

In his previous life, he was the strongest demon-slayer in the Qingyang Dynasty, "Zhongzhonglou", and he killed the thirteen demon kings of the Northern Wilderness with a demon-slaying sword. His most trusted junior brother stabbed him through the heart with a sword from behind. He died with a smile on his face, only regretting that he could not kill all the evil spirits in the world. When he opened his eyes again, he became a black wind demon wolf cub that had been abandoned by its mother wolf when it was born. It had weak limbs and no demon power. Standing in front of him was a group of fellow disciples and nephews who made a living by hunting demons. They poked him in the belly with the tip of their swords: "This beast's inner elixir has not yet formed, let's stew it." Zhonglou looked at the face of his junior disciple and slowly opened his wolf mouth, "Since this body is born to be a demon, then I don't mind and will swallow you all up." When the last demon-slayer becomes the strongest demon, why should the human race talk about "killing evil"?
