In the chaotic times of the late Han Dynasty, there were wars everywhere, food shortages were everywhere, and human lives were like grass and grass. Su Yanzhi was originally an ordinary farmer in the suburbs of Luoyang. He took care of his father Su Wangshu, mother Wen Yuheng, and his wife Shen Qingyan. They just wanted to survive in troubled times and protect their family. Unexpectedly, the opportunity of "one piece of information every day" unexpectedly opens up. He may hear about the rise and fall of food prices, he may know the movements of soldiers, he may learn the secrets of princes, or he may learn how to avoid danger.
From relying on food information in exchange for half a bag of corn to tide over difficulties in lean years, to using intelligence on the movements of princes to open up trade routes; from supplying food for Cao's army and offering suggestions for a surprise attack on Wuchao, to traveling across the three kingdoms of Wei, Shu and Wu in cross-border trade; from avoiding the war in Guandu and hiding from the beacon smoke at Chibi, to using intelligence to predict chess games in troubled times, hoarding supplies, expanding trade routes, and buying land. Su Yanzhi grew up step by step from a low-level farmer to a wealthy businessman across the north and south.
He uses intelligence as a blade to break the confusion of troubled times and avoid the disasters of weapons and weapons; he takes his family as his consideration, protects the health of his parents, stays with his wife, and teaches his eldest son Su Chengyan and second son Su Chengyan to study intelligence and guard the family and business. There is no pride in galloping on the battlefield, no ambition to rule the country, only a simple obsession - to protect the peace of a family with one piece of information a day.
From surviving in the famine in the last years of the Ling Emperor, to the expansion of the trade routes of the Three Kingdoms, to the eternity of the family established by the Jin Dynasty, the Su Yan family, in the chaotic times of war, used intelligence as a boat and warmth as a sail. In the shadow of swords and swords, they blazed a unique road of protecting the family, building a business, and passing on the family, hiding the simplest perseverance and perfection of people in troubled times.
