Recreating Earth's Civilization in the Primitive Era

It's not routine, it's not invincible, it's not systematic, it's not brainless, it's not cool. With a book in hand, I own the world. The author is determined to create a secret book of time travel and a guide to rebirth that all readers can use. Xia Yan accidentally traveled back to the primitive era and led the Chinese people who were still in the primitive era to cultivate land, burn pottery, smelt metals, and tan furs. Based on the development history of Chinese civilization, he copied all the discoveries and creations in the history of Chinese civilization, rebuilt the Chinese civilization step by step in the new era, and ultimately allowed the Chinese civilization to be passed on and continued forever.
