Lin Mu, a graduate student in history, came into contact with an ancient mirror from the Northern Song Dynasty during an archaeological trip, and his soul traveled to Kaifeng Mansion in the third year of Yuanfu (1100), where he became a down-and-out scholar who committed suicide by drowning himself in a river.
He was penniless, his family was destitute, and he had no relatives. He made a living by selling calligraphy and paintings, and used modern knowledge to improve soap formulas. Starting from a small workshop in the market, he gradually built the "Qinghetang" business name. Just when he thought he could rely on business and technology to make a living, he ran into the darkest power whirlpool in the late Northern Song Dynasty - the eunuch Yang Jian, the traitor Cai Jing, and the "six thieves" Wang Fu, all of whom wanted his life.
What's even more cruel is that he knows the countdown of history: there are only 27 years left before the disgrace of Jingkang.
The foolish move of uniting the Jin Dynasty to destroy the Liao Dynasty is about to be staged, and the Jin people's cavalry are sharpening their swords. He tried to write an early warning, train troops, collect food, improve gunpowder, and stick to the truth, but he found that it was far more difficult than imagined for one person to fight against the entire decadent dynasty.
This is the story of one person's struggle to survive, and the tragedy of a group of people who know they cannot do anything. When the prosperity comes to an end and the two emperors hunt north, the real heroes are not those who talk loudly in the court, but those who protect the people from the ruins and leave the fire for Chinese civilization.
