Seige On The Myriad Castle

The demon general's task during these attacks was not to win the battle against the stronghold. Their task was to make sure that the stronghold did not have the ability to launch a counterattack against them. So, they were focusing more on launching spells from a distance and avoiding direct confrontation unless absolutely necessary. 

When Duke Grant's son, James, as well as the other angels, arrived to provide support, they realized that the demons were already gone, and they were stunned when a new fire rose on the horizon, showing that another stronghold had been attacked by the demons. James frowned in irritation and told some of the angels to help out those who had been injured, while the others should come with him as they moved to the next stronghold. James knew that there was something wrong here. If the demons had only just burned this stronghold down, how were they able to get to the next one so quickly?
