Liang Xiao, the poorest student in Northern China, accidentally traveled to Daxia, the female dynasty, after failing the college entrance examination. Women are in charge here, and men can only take care of their wives and children. What's even more outrageous is that as soon as he opened his eyes, he found that he was being stuffed into a sedan chair and was about to marry the most ruthless powerful official in the capital - Zhenbei King Xiao Yan.
According to rumors, Xiao Yan was cold-blooded and ruthless, killing without blinking an eye, and the man he married could not survive more than three days. But before Liang Xiao could escape, he bumped into the hypocritical smiling face of the original owner's best friend Su Wanqing: "Brother, go die for me!"
It turned out that Su Wanqing was the one engaged to Xiao Yan, but because she was afraid of being tortured, she arranged for Liang Xiao to marry her instead. Liang Xiao was angry: Bullying me? I'll let you know what "hell difficulty" is!
On the wedding night, he took out the "Five-Year College Entrance Examination and Three-Year Simulation" he carried with him, and smiled charmingly at Xiao Yan: "Your Majesty, I want to take the first prize in the examination."
Xiao Yan pinched his chin with a cold face: "Would you like to take one test?"
When Liang Xiao used the nine-year compulsory education knowledge to crush the civil and military forces of the Manchu Dynasty, and used the principles of physics and chemistry to blow up the enemy's camp, the dignitaries of the female dynasty were dumbfounded - this man could actually change the world?
However, as the secrets behind Xiao Yan gradually surfaced, Liang Xiao discovered that there was a bigger conspiracy hidden behind this replacement marriage...
