Li Xuan chose the battlefield for the decisive confrontation to be a flat land thirty li north of Nanchang, arrayed with the support of several hills.
The area surrounding Nanchang city was mostly flat farmland, with the rest either being muddy swamps or low hills, devoid of any favorable terrain to rely on.
However, these farmlands and swamps were the most advantageous terrain for the Shenji right and left camp.
It was the early summer, and the soil in the rice fields was soft, moist, and slippery, stepping into it would mean sinking into a deep pit.
When the Shenji right and left camp was divided into a hundred Line Column Formations on the ridges of the fields, the area within three hundred and eighty zhang in front of them turned into an unsurpassable death trap.
