Gong Yelong, a history graduate student, accidentally dug up a black jade tablet with micro carvings.
The next second, he was engulfed in white light and opened his eyes - standing in front of him was Qin Shihuang wearing a twelve-pointed crown.
"Have you come since two thousand years ago? I have been waiting for you for a long time."
Only then did Gong Yelong discover that there was a volume of "Ancient Times" that was neither bamboo slips nor silk script hidden on Qin Shihuang's bookshelf.
It records a civilization earlier than the Xia, Shang and Zhou dynasties and more mysterious than the Three Sovereigns and Five Emperors - Huaxu.
This civilization had cities, writing, geothermal heating, and even mastered nanoscale carving technology 10,000 years ago.
What Qin Shihuang read was this set of "his own five thousand years" - the history of Huaxu in the five thousand years before the Qin Dynasty.
After he finished reading, he broke his defense:
"The three-generation rule promoted by Confucianism is nothing but the residue of the decline of Huaxu. What I want to burn is fake history; what I want to trap are those who know the truth but spread lies!"
Gong Yelong was forced to become Qin Shihuang's "recorder", accompanying him on his eastward tour, helping him interpret the jade tablets, and even witnessed the changes in the sand dunes with his own eyes.
But he also has an even crazier mission: to return to modern times with the truth about Huaxu Civilization and rewrite everyone's historical understanding.
This book is all the memories he brought back.
"The five thousand years you thought were only the first half of the book read by Qin Shihuang."
