Because the Great Tang Empire Navy first needed to eliminate the threatening targets in the Endless Sea, each country's navy had already suffered heavy losses.
The main forces of the Dorne Navy were completely annihilated during the battle between Tang Country and Qin Country; the Laines Empire Navy also lost everything in a failed raid on Dragon Island.
The Ice Cold Empire was never a traditional naval powerhouse; they were bogged down for a year in their war with the Elves and their navy wasn't particularly large.
Even so, their Navy was annihilated by the Tang Country Navy near Hotwind Port, leaving only some destroyers and other small vessels.
The situation for the Elves was similar to the Dwarves; their navy's development was delayed by wars with each other, and although they later managed to build some main warships and aircraft carriers, they were all wiped out by the Tang Army outside Hotwind Port.
