Umegorō, having served Katsu Rintarō for many years as an attendant, has gained some understanding of military science through Katsu Rintarō's influence.
Without needing detailed instructions from Katsu Rintarō, just a few simple directives suffice for Umegorō to grasp the kind of fortifications Katsu Rintarō wants to build.
Simply put—Katsu Rintarō wants him to construct several tall walls to block the enemy; the more and higher the walls, the better.
As he and Umegorō arrived at the western corridor of the rooftop, Katsu Rintarō nodded with satisfaction at the sight of the defensive structures now spanning the corridor: "Very good... Umegorō, you've done well."
Umegorō did much better than he had imagined.
In such a short time, Umegorō had organized the group to build three walls, each about 2 meters high. Although not particularly sturdy, they wouldn't collapse with a single push.
