As a good ruler concerned for the wellbeing of his citizens, Rino decided to launch a sudden attack on his territory to see how they would react.
This was probably the last thing he wanted to do before leaving Noir Province for an indefinite period. His new daily quest arrived, and Rino had all the reasons to leave this village in search of a new territory space.
He did not want to break the barrier he painstakingly set up, but there was a need to scare his army. The strength of a kingdom's defence depended on how ready for an attack the army at the border was. Distant water cannot put out a near fire, and Rino hoped that his shadow army was prepared for the worst in his absence.
Just a few hours earlier, Fronzo presented Rino with the sapling of a magic tree from cross-breeding World Tree Rino and the Cypress Ghost Tree. There was no longer a reason for Rino to remain lingering in Noir Province once the villagers passed this test.
