"Hachiman Mahasattva, protect us! The Samurai of Korea rarely have the will to fight to the end. Their Military Households' weapons and equipment are even more rudimentary than the Ashigaru at the village head... The only thing that troubles the Samurai of Kyushu is Korea's Naval Forces! Those patrolling board ships are much more formidable than our small early ships and customs ships. They conscript labor, and their shipbuilding speed is indeed very fast! Even if we go to great lengths to burn a few of the Naval Forces' board ships, Korea will quickly build new ones..."
The shipbuilding level of Wa Country's various nations has long been at the bottom among East Asian countries, only slightly better than Mongolia. Before Wang Zhi, the Five-Peak Ship Master, established himself in Hirado and brought the advanced shipbuilding technology of the Ming Dynasty, Wa Country's shipbuilding level lagged two eras behind the Ming Dynasty and one era behind Korea!
