Bone Rain in the Sky of Corpses and Song of the Deep Soil Ridge

The world is a giant rotting corpse, and the sky is its cracked skull; bones are raining down, and sentient beings are reincarnating between the corpse soil and the spine. Cultivation is to put "oneself" back into the corpse again - and the protagonist wants to dismantle the corpse and build a spine that truly belongs to a living person. The core mix-and-match setting has zero technology and zero overlap: 1. World = "The Dead Soil and the Sky": The earth is the belly of a giant corpse that is festering, and the sky is its broken skull; the rain of bones falls from the cracks in the skull, serving as both nourishment and curse. 2. Cultivation system = "Corpse Fragrance Spine": ? First inhale the corpse incense → the body rots → the soul wakes up; ? Recover the bones and rain→reshape the bones→form into a spine beast; ? The final form = "The Spine that Supports the Sky", embeds itself into the cracks in the sky and replaces the bones of the giant corpse. 3. The ultimate contradiction: ? Supporting the sky = eternal imprisonment, not supporting it = the sky collapses and corpses collapse, and all living beings instantly turn into pus; ? The protagonist discovers that the giant corpse is actually not dead yet. It will wake up once the bones are put together, and all the "spine beasts" will be swallowed back into the body by it.
