As Rose requested, Noel went around his territory to inspect the defenses personally. If the people knew that the inspection was satisfactory even to their lord, they would feel much more assured.
They would believe that even if the demons came, they could withstand their attack.
This was Rose's original intention, and Noel raised their morale even further by doing a lot of other things.
With his speed as a spirit king, he could travel basically to every corner of his territory in less than twenty minutes.
Including the inspection, he managed to get one city done in one and a half hours for one city. In the end, he finished the inspection within two days.
Then he moved to the three cities she specifically requested. Tristan's city could be said to be the most fortified.
As the Rune Meister, Tristan actually filled the city with numerous runes. They even dug more trenches and filled them with runes that could be activated in secret.
