Su Qinghe, a female doctor in the Department of Modern History, was accidentally sucked into the parallel world in the book - the Liang Dynasty - while studying an exclusive copy of "Longxi Chronicles" from the Tang Dynasty. When she woke up, it was a sedan being carried into the Marquis of Jin'an's mansion. She was a substitute bride being used to pay off the family's debts.
She thought she would be able to get by with her knowledge of history, but found that she knew nothing about this world - this was not any dynasty she studied, but a parallel time and space that had never existed. And her only "golden finger" is the "Longxi Chronicle" that she brought with her, but what is recorded in this book is actually the "future" of this world.
What's even more fatal is that the book says: The Liang Dynasty will be destroyed in three years, and the trigger of the collapse is none other than her husband, Pei Yun, the Marquis of Jin'an. In the book, Pei Yun was nailed to the history books and charged with "collaborating with the enemy and treason, and massacred the city for three thousand miles."
Su Qinghe's mission is simple: survive and then leave this man who is about to collapse.
But she soon discovered that Pei Yun was completely different from the historical records she had read. Under his cold and restrained mask, he hides his deepest hatred for this decadent dynasty; he does not collaborate with the enemy, he just wants to overthrow the world.
And she discovered even later that she had not traveled through time accidentally. That "Longxi Chronicle" was originally the last letter for help left to her by someone across time and space.
