Drawings for burning fires, drawing water conservancy projects, and calculating logistics accounts, the man in science and engineering has a golden finger. He improved the tiger crouching cannon to blast the shield-breaking vehicle formation, dug ditches and cultivated fields to raise 10,000 elite soldiers, and the three-stage flintlock attack made the Jianlu doubt his life.
