Darkness. A hospital room. The sound of a mother’s muffled sobs. That was supposed to be the end of Ren's exhausting life. Instead, he wakes up suffocating, breaking through a thick calcium shell, and tumbling onto the damp floor of a primeval jungle. Reincarnated? Yes. But there are no beautiful goddesses, no legendary swords, and no cozy medieval kingdoms. Ren has been dropped into a lawless, prehistoric meat-grinder where humans aren't at the top of the food chain. Armed only with a cold, flickering system notification that declares his state as 'Critical,' he must navigate a brutal world where monolithic predators rule the earth. In this prehistoric nightmare, survival isn't a guarantee—it's a blood-soaked currency. And his neighbors are very, very hungry. [What to expect:] Weak-to-strong progression (LitRPG/System elements). Dark, grimdark atmosphere & survival themes. A brutal, prehistoric world filled with ancient dangers.
