[Dinosaurs] + [Reborn] + [Evolution]
Lin Lie is reborn in the Cretaceous period as a Troodon abandoned by its tribe because of its frail health.
In this age of roaming giant beasts, he should have been at the bottom of the food chain, destined to become a snack for a Tyrannosaurus rex.
Then he discovers that the calcium he eats isn't excreted. Instead, it turns into black bone armor covering his body.
A Velociraptor's claws can't even scratch his eyelids, and a Tyrannosaurus rex's bite shatters its own teeth.
Over the long ages, he gradually learns how to use his mutation to survive, eventually becoming the ruler of the Cretaceous.
