Slowly

Wang Chen discovered that he, a beastmaster, was suddenly invincible in all the heavens and worlds!

Billions of humans around the world are reincarnated in the war continent, become lords, and compete for supremacy with all races.

Everyone will randomly gain the power to recruit soldiers, recruit various powerful soldiers, and plunder each other's resources.

The type of troops Li Yuan recruited were the Black Shadow Corps.

Endless, immortal, a weapon of war created for killing.

Wherever the troops point to, all this land becomes the king’s land!

From a lord to a city lord, and then to the eternal and immortal Black Shadow Dynasty, he was invincible all the way!

[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.
