"However, this is still not enough."
After organizing his thoughts about Nanhai Country, Lu Yuan then unfolded a map, which displayed the entire landscape of Yangzhou with its mountains and rivers, cities, and settlements, all spread out before him.
In some respects, Nanhai Country could actually be considered a hub.
Located in South Sea Prefecture, it borders Dongting to the north, Yulin to the west, Jianan to the east, Yuzhang to the northeast, and the boundless Southsea to the south. This location can truly be described as a crossroads connecting five regions.
If one holds this prefecture, whether marching north, east, west, or south, one can strike out in all directions. There are convenient sea routes to the east, west, and south, allowing for easy transportation of troops and supplies by ship.
Historically, any Jiangnan army aiming to strategize over Lingnan would always first target Southsea.
