Shireck's advisors had left, and they had their ways of leaving Beiyuan City no matter what. These men took small boats from the docks at night before transferring to larger ships to return to Shen Country, even escorted by warships along the way.
Now, because Tang Country warships frequently attacked Shen Country transport ships, the shipping route between Beiyuan and Shen Country was no longer safe.
So whether it was transporting materials or troops, escort by warships was required. However, compared to the number of transport ships, there clearly weren't enough Shen Country warships to go around.
This directly led to a serious problem: whether it was because the ports were destroyed, or transport required escort, the total volume of shipments to Beiyuan City from Shen Country had been reduced by four-fifths!
Eighty percent, a full eighty percent!
