Once in time, Lin Yan, a top student in modern history, became a failed scholar from a poor family.
The family is surrounded by poverty, creditors are coming to visit, and even poisonous poisons are secretly watching.
In this troubled world where imperial power is declining and there are many powerful families, he originally wanted to use modern knowledge to live a stable life, but he was forced to be involved in the torrent of the times.
Starting from improving farm tools and outsmarting the squires, to solving strange cases, quelling famines, entering the court, and establishing frontiers...
He innovated skills with engineering thinking, discerned opportunities with historical perspective, and counterattacked from the bottom step by step, eventually becoming a powerful official from a humble family who dominated the government.
