"Five to six thousand monsters?!!" exclaimed Angus.
Although most of the monsters in the outer area consist of low-grade monsters, with only a few reach fourth grade. Five and six thousand monsters are enough force to overthrow the entire Black Fortress.
Furthermore, with the lead of a fourth-grade monster, the other lower-grade monster will not blindly charge at the Black Fortress and fall into the trap. There are also chances of a fifth-grade monster among these monster waves.
If it is only a fourth-grade monster, Angus may be able to handle it using all kinds of his power. But, if it is a fifth-grade monster, he is not sure he could kill it even with the help of everyone. Therefore, their current situation is quite severe.
"Did you already tell my father about this?" asked Angus.
