Archaeologist Lin Mo's tomb collapsed and he accidentally entered the "barbaric" Qin Village. With the help of modern technology, he created water purification, healed serious injuries, educated young children, hunted giant beasts, and established mountain villages.

Should he be trapped in a mountain village, or should he step into the imperial capital of Xianyang and stir up troubles in the world? Knowledge is the strongest power!
