Sam is on a repetitive process now. On the Level 6 beast, moving from one dukedom to another is only a day's worth of journey.
In every Dukedom, his first target is a resource point and his second target is the Dukedom capital, luring the beasts towards the city and then again the third target is the remaining resource points.
He took over fifteen days in a single Dukedom and he is making great progress.
In next month. The western star and the Northwestern star are in trouble. Emperor is fuming mad because in every border that Sam attacked there is a declaration of war from the Arian empire.
He can invade on the remaining borders if he wants to, but the main problem is the resource scarcity.
For every major resource that gets eliminated, there will be more stress on other fronts. So, he cannot take the initiative.
He is clearly regretting not sending a Marshall, a Pre-transcendent to attack Sam when he escaped at the first time.
