"Nan Feng thinks this way. First, if the water route through Teng County is allowed, the people in this area will have to relocate. Although this saves time, people who have lived in a place for a long time usually do not want to move. Second, this area is close to the mountains. To proceed, we'd have to dig through the mountains and drain the water from here. Nan Feng considers this extremely costly and labor-intensive. Therefore, after weighing the options, Nan Feng still believes the third option is the most reliable. Despite the longer time required, it saves a lot of money and spares the people the trouble of having to move."
Nan Feng analyzed the situation clearly, and the Emperor, who was originally undecided, had an answer once he heard her input.
Looking at Nan Feng now, she seemed more like a highly knowledgeable woman than someone who only knew how to farm and do business.
