Gu Chen woke up in a nightmare: a primitive stone-age tribe where humans are livestock. Every year, his people must offer ten young souls to a monstrous Sacrificial God, or face annihilation. Now the cruel deity demands twenty.

But Gu Chen is no ordinary clan leader. Armed with a sharpened stone spear and a 21st-century mind, he refuses to kneel. In a savage wilderness ruled by colossal beasts and predatory Hundred Clans, humanity is the weakest link—bred as slaves and sacrifices.

Drawing his blade, Gu Chen roars a defiant oath that will shake the world: "Kill one of us, and we exterminate your entire clan!"

With the blood of gods and monsters, he will forge the immortal heroic soul of humankind. The age of sacrifice is over. The age of war has begun.
