After falling off a cliff and waking up, Xu Chen found himself surrounded by a group of naked savages.
They ate raw food and drank blood, and men and women lived together. That was bad enough, but they also ground their teeth and snored in their sleep, farted while eating, and didn't wash their hands after using the bathroom...
Xu Chen swore he'd transform these primitive people into civilized, polite, idealistic, ambitious people of a new era.
So he became the Rope-Maker, the Basket-Weaver, the Farmer, and the House-Builder, leading the primitives in their struggle against heaven and earth.
To commemorate his great achievements, he recorded every success in his diary.
