How a Realist Hero Rebuilt the Kingdom (Manga) Volume 3

The Subjugation War Begins! With supplies carried, plans made, and alliances forged, Souma's mission to subdue the rebelling nobility has begun. With a pocket full of tricks, loyal subjects, and modern knowledge, this should be easy! Well... not if you want your civilians to escape unharmed. Or if adventurers keep treading across the battlefield. Or if your nosy neighbors think this might be the best time to launch an invasion of their own. Still, rational thinking will prevail... right?
