Regarding the issue of the navy, back in the years when it was still the Changsha Kingdom, Lu Yuan deeply realized this deficiency when he led the Three-Nation Alliance against Ning Country.
With just 50,000 troops, Ning Country's navy directly split Dongting County in half, isolating the Changsha Kingdom from north to south.
At that time, the transportation between the north and south of Changsha was cut off.
Merchants and travelers were blocked at various ports. Domestic government orders were delayed and stagnated. Communication between the north and south even required sending martial arts experts on small boats to sneak through Ning Country's naval blockade.
One could almost say that as soon as their blockade of the Yangtze River was in place, the Changsha Kingdom was almost paralyzed.
Such a lesson was fresh in his memory, and after just over half a year, Lu Yuan had not forgotten it.
