Staying in the Demon Gate and Becoming a Saint by Picking up Corpses

"The corpses pave the way forward, and the burial ground controls the heavens!" When Yu Yao opened his eyes, it was purgatory on earth. His mother turned into blood mist, and the villagers died tragically in front of his eyes. The [body collection and burial system] became his only way to survive. Picking up corpses will lead to breakthroughs in cultivation, picking up corpses will reveal top-notch stealth techniques, and picking up corpses will extract opportunities from the heavens! The Holy Moon Demon Sect eats people without spitting out their bones, but for Yuyao, this place is full of "treasures". A fiery demon cultivator maid? The soul contract is here to be your exclusive confidant. A sinister and vicious demon general? I will step on your bones to become a god. Unlock the space of the burial ground, isolate the world from exploration, and double the speed of time. Let you kill the outside world in darkness, and I will smile and watch the storm from inside the burial ground. From the low-level ants who picked up corpses to the supreme Holy Lord who buried all the heavens. Yu Yao: "Don't worry, after I finish picking up this body, I will send you to see them."
