In the beginning, when Caroline received Leo Ray's arrangement to lead the team to attack the eight enemy legions stationed at the entrance of the galaxy corridor, she was actually full of suspicion.
After all, according to the intelligence, the soldiers of these eight enemy legions have already set up a strong defense position at the entrance of the galaxy corridor, using City Building Skill, Swamp Skill, Abatis, and chevaux-de-frise to deal with the possible allied forces.
In the face of the enemy's perfect measures, launching a raid with limited friendly forces seemed unwise no matter how she thought of it.
It should be known that, theoretically speaking, the difficulty of this type of siege is no less than attacking a city with tall walls and deep moats.
Even though the Northern Army is more brave and skilled, with Hilda's Blade Legion leading the attack, it's by no means easy to break through such a defensive line.
