Reborn as a Demon Bone, Start with a Forbidden Body

Fantasy [Rebirth, alien beast style, non-human protagonist, no system, growth, wits, monster clan, decisive killing] Zhou Ye died on the bone-breaking table of the Boneyard. When he opened his eyes again, he was reborn as a black life bone that no one wanted in the Ten Thousand Monsters Pit. No blood or flesh, no arms or legs, just seven empty bone sockets. The second bone-scraping bell has already rung. When the gate of the pit is opened, he will be ground into bone powder together with the broken bones in the pit. In his previous life, he tried bones for others. It is never your turn to decide what to connect or dismantle. In this life, he picked up the backbone of a rotting swamp bone loach and crawled out of the mud; he picked up the skull of a gray-beaked crow and used other people's voices to deceive hunters; he also selected a three-ling baht grain-carrying ant arm to protect a strong bone worth twenty-seven soul baht. Once the seven slots are written, changing bones means permanently losing the old bones. A sacred bone may break a spine, but a useless bone can be worth a hundred times in the right place. What Zhou Ye wants to build is never the strongest body in the eyes of the world, but a body that truly belongs to him. It wasn't until the Xuanzi bone search order from the imperial treasury fell into the Ten Thousand Demons Pit that he discovered that the most heavily guarded forbidden treasury in the world actually contained a complete skeleton with the same origin as his. But does he still want the body that was born to be his?
