In the original dark forest, Wu Yu wakes up; he has traveled through time. Surrounding him are a group of naked, scar-covered savages.

They wear only animal skins on their upper bodies, making Wu Yu wonder if he has entered the set of a prehistoric movie. However, soon Wu Yu realizes that he has not only traveled to the primitive era but also integrated the memories of a young boy named Yu into his mind—he has become the holder of the tribe's mystical power, a disciple of the Wizard.

The tribe faces a sneak attack, and amidst the blood and gore, they must continue to survive. Wu Yu, faced with this sudden change, how will he lead his people to break through the encirclement, from weakness to strength, becoming an unshakable presence in the tribe?

The cruelty and beauty of the primitive world, the coexistence of mystery and the unknown, and Wu Yu, holding the power to rewrite it all.
