This show takes a premise that could be generic, modern guy thrust into ancient world, and makes it about survival against impossible odds with no safety net. Jiang Hao isn't chosen or special; he's a pawn with a broken power source trying to outthink enemies who have been perfecting warfare since before civilization existed. The wilderness itself becomes the real antagonist, not just the people in it. Every fight drains his incomplete totem further, so you're always watching him calculate whether he can afford the next battle. The show respects the weight of that math in a way most action shows don't bother with. He's not getting stronger, he's getting smarter about staying alive.

Jiang Hao is a young man from the modern world, once used as a piece in someone else's game, who sets out into a prehistoric wilderness to learn what became of his father. He carries an incomplete totem known as a power bank. Across the Six Wastelands he clashes with primitive tribes, reaches a mysterious ancient city, hunts ancient beasts and learns totem witchcraft from them. Then a strange light appears in the sky and threatens to swallow the whole land. This short action fantasy ONA runs seven episodes.
