The second weakness is to overload the Magic Breaker by using spells beyond its carrying capacity, which only the Red Night can do.
However, similarly, as long as the White Knight opens the energy fortress, it would still turn into a long battle of attrition.
Moreover, faced with the fierce four-sided attack of their current opponent, even if they could suppress one side, the other three sides would still be unresolved, and the situation would be extremely unfavorable.
As for the third weakness, waiting until the magic power of these Magic Breakers is exhausted and they voluntarily stop their space transfer technique is even more impractical.
Not to mention whether the absolute defense barrier of the territory could hold on until that moment.
You should know that all the magic cannons in the territory are powered by the Demon Energy Luminous Crystal.
