To be fair, one could not say that all of the Great Horn Army's soldiers were daydreaming.
After all, Hundred Blade City was an important place in Picturesque Orchid that had thousands of years of history. No one could bear the responsibility of handing the glorious city over to the rat people.
Furthermore, Hundred Blade City had a large amount of military rations. Not only did they need to provide for the Wolf Clan's daily consumption, but they also needed to prepare for the entire Gold Clan to get through years of battle between the five clans and even the War of Glory.
If all the military rations were burnt, how would the wolves and leopards of the golden clan fill their stomachs and advance toward the land of Holy Light?
Therefore, unless it was absolutely necessary, the Wolf clan would never burn the military rations. This was more of a test of the commander's determination than a brave warrior cutting his wrists.
