Chen Xiaofan never dreamed that he, a financial migrant worker in the 21st century, would time travel to the Tang Dynasty and become Li Shimin's "distant cousin" because he complained that the plot of "The Reign of Zhenguan" was too fake.
The beginning is on hell difficulty - he is being surrounded by a group of angry people because he used "modern financial knowledge" to trick them into investing in a "silk futures" project that does not exist. Seeing that he was about to be beaten into a pig's head, he suddenly thought: "Dear fellow villagers! I was ordered by Your Majesty to test the public sentiment! Now that the test is over, double the amount will be returned!"
Relying on his ability to talk dead people back to life and a lot of modern knowledge, he actually prospered during the Zhenguan period: he designed the "Zhenguan Lottery" for Cheng Yaojin to make money, helped Wei Zheng develop a "public opinion monitoring system", and built the first obstetrics and gynecology hospital in the Tang Dynasty for Empress Changsun... Every time he came up with a new trick, all the civil and military officials in the court would be shocked.
But as he gradually integrated into this era, he discovered that changing history is not that simple. The obstruction from the aristocratic family, the threat from the Turks, the doubts from the conservatives... And that Wei Zheng who always looked at him like a liar. Chen Xiaofan must prove that his modern wisdom is not a miraculous skill, but a real ability that can make the Tang Dynasty more powerful!
From the opportunistic "strong-mouthed king" to a capable minister who cares about the world; from the "charlatan" who everyone calls and beats, to "Mr. Chen" who is respected by all people. This is a knowledge revolution that spans thousands of years, and it is also a legend of a useless counterattack.
