History graduate student Shen Jun traveled back in time to the late Northern Song Dynasty and became the adopted son of a small cloth shop in Bianjing City.
He remembered the ending of the Jingkang Disgrace, but not the details; he knew the general direction of the gunpowder formula, but had to try out the proportions from blasting the furnace again and again; he worked under the old coach of the Western Army to practice military formation boxing, but was told that he started too late and would be second-rate in his life.
All plug-ins are unreliable. The only reliable thing is the profitable cloth shop, the group of field soldiers trained from the refugees, and a wheat field that has been watered by iron and blood for thirty years.
A country cannot be conquered. It is sown.
