Hitting the enemy where it hurt was Arthur's plan. As before, he tasted and knew the value of paralyzing the enemy's connection and communication routes.
Doing so would buy him a lot of time. For instance all the forces scattered inside his empire would be isolated.
They wouldn't be able to even know where Arthur was hitting. They wouldn't be able to adjust their movement and wouldn't be able to support themselves.
Plus he didn't know what the grandmaster of the dark angel clan was able to do. Arthur didn't know if that despicable mage could spy on his empire or not.
So he had to be cautious and not let his enemy have any moment of rest. All the advantages his enemy had would be instantly vanished by this simple move.
But Arthur was quite sure this fight wouldn't end up as easily as anyone would think!
