Dinosaur+Rebirth+Evolution
Lin Lie was reborn and returned to the Cretaceous Period, becoming a troodon that was abandoned by the tribe because of its frailty.
In this era of rampant giant beasts, as the bottom of the food chain, he should have become the tooth sacrifice of the Tyrannosaurus Rex.
Until he discovered that the calcium he ate would not be excreted, but would be converted into black bone armor covering the body surface.
The Velociraptor's claws could not grasp his eyelids, and the Tyrannosaurus Rex's bite broke its teeth.
Over the long years, he gradually mastered how to use his mutations to survive, and eventually became the overlord of the Cretaceous.
