Everyone Transmigrates to Cultivate Immortality, and I Have a Cosmic Gate!

Eight billion people around the world transmigrate en masse to a cultivation world, each possessing the body of a low-level cultivator! Everyone receives a low-tier legacy and inheritance. Zhao Shuo looks at his trash spiritual roots and feels like the sky has fallen! Fortunately, there's always a way out. He discovers a Gate of the Cosmos in his sea of consciousness, and passing through it takes him to a doomsday planet! Zombies have human skin, blood, living souls, bones, resentment... Refine living souls into a Soul-Refining Banner; ten-soul banner → hundred-soul banner → thousand-soul banner → ten-thousand-soul banner... Venerable Soul Banner... Immortal Soul Banner; Cultivate with blood to master blood-path techniques; Refine bones into a Mighty Demon God Banner; White Bone Demon → Mighty Bone Demon → Mighty White Bone God-Demon → Twin Mighty White Bone God-Demon; living souls + Blood God Scripture + bones → Blood Soul Banner; Human skin → refine into a Painted-Skin Puppet; Years later; Zhao Shuo ascends to immortality in a shower of rosy light, and heavenly merit rains down. Everyone is left dumbfounded; The Blue Star cultivators still struggling at the bottom can't help shouting: "Holy crap, he's cheating!" "How can a demonic cultivator be protected by merit?"
