Lin Che, a doctor of modern philosophy, traveled through time and became a minor official in the Ministry of Rites in the late Ming Dynasty. He has no gunpowder technology and no domineering spirit. He only brings a set of deadly thinking weapons-system theory and data modeling.
When Chongzhen was worried about Liao's pay, he handed over the "Twelve-ring Flow Chart for the Loss of Military Pay"; when officials were arguing about the Shaanxi Civil War, he came up with the "People's Livelihood Pressure Risk Early Warning Model". In the abyss of Yangzhou's salt policy, he cut through a century-old network of interests and used a salt policy reconstruction plan to pry back tens of millions of silver for the dying Ming Dynasty.
This is a scalpel of thought used to scrape the bones and heal the poison of the ancient empire. See how a modern soul uses data as a sword and the system as a shield to reconstruct the last glimmer of light in the deadlock of history.
