A modern city full of evil spirits and anomalies.

Ji Li, who failed in mechanical ascension, found himself turned into a weak natural person and was nailed upside down on a cross.

Fortunately, his intelligent core "Ascension Protocol" originally integrated in the brain in the tank is still functioning normally, and has a small chemical reaction with this strange world.

"Whether it is a ghost or an evil spirit, I will turn you all into my prosthesis."

"Your evil spirit can transform into a vampire, but I am a Cybertronian."

The devil comes from the human heart; unnatural death, alienated mental illness, evil spirits, cognitive weapons, soul wells...

cognition determines power; contracted demons, mourners, wanderers, splitters...

the world overlaps and grows; the inner world, the reflection world, the spirit hell...

[Flesh + Bones + Doomsday Disaster + Lovecraftian Survival + Civilization Graveyard]

When the mist descended and aberrant horrors howled outside the windows, all players cowered in crumbling shelters, trembling. But Bai Yi found himself teleported right onto the face of the deity "Endless Flesh," witnessing the terrifying feast of the flesh planet being devoured by something even more monstrous—the splattered fragments of flesh and bone that rained down became his only beginner's gift.

Some used mystical seeds to upgrade their shelters, striving to cultivate a World Tree. Others fused theirs with eldritch idols, attempting to establish a Great Cult. And some utilized remnants of lost technology to fortify their shelters, hoping to resist the calamity with science.

Bai Yi, however, fused his shelter with endlessly proliferating flesh and bone.

On the day of its evolution, newly formed bone plates structured themselves into a honeycomb-like support system within the fleshy walls, their surfaces covered in a translucent membrane that revealed the pulsating network of veins beneath. The ceiling sprouted rib-like skeletal rings, while the floor was overgrown with writhing flesh, from which occasional tentacles slithered out.

"Can this... really still be called a shelter?"

Staring at the fully transformed, flesh-and-bone abomination of a refuge, Bai Yi gulped.
