A Different Magical Energy

The protective barrier was magical. People inside could attack the enemies outside, but the enemies outside could not penetrate the barrier. To the enemies outside, other than breaking the protective barrier with a powerful force, all they could do was launch sustained attacks to deplete the energy of the barrier.

Without anything holding them back, the Evil Eyes and spider army retaliated with full force. As they had a higher range, the Evil Eyes were mainly responsible for attacking the Giant Crab Spiders that were a dozen steps away, their concentrated beams of light never stopping. The spider army was responsible for attacking the Giant Crab Spiders within ten steps from them. Even though their poison was not as terrifying as that of their opponents, they managed to clear large areas of their enemies with their numbers alone.
