I Became a Saint Through Merit in the Demon Sect

Lu Yu traveled through the world of immortality and became a registered disciple of the Demonic Soul Refining Sect. He was about to be expelled from the sect because he could not pay the interest and was turned into a material. I thought it was the beginning of the collapse of heaven, but I didn't expect that there was a portal in the sea of ​​​​consciousness that could travel freely to the doomsday world. In the apocalyptic world, zombies are everywhere and humans are struggling to survive, but for Lu Yu, this place is like paradise. Zombies are great, zombies are full of treasures. The living soul can be used to achieve breakthroughs in cultivation, the flesh and blood can be used to practice Taoism, and the skin and bones can be used to strengthen magic weapons. All kinds of magic techniques are at his fingertips. "My hands are stained with blood, but I have never killed anyone!" "You asked me how my merits made me a saint? I didn't expect that killing zombies would have merits!" "You ask what this spiritual treasure of merit is in my hand? Oh, the Ten Thousand Souls Banner."
