Aliya instantly created the fire zone. The whole area that was in the range of that attack already fell with fire and every Monsters present there already begin to burn. If you are wondering about the fire zone then it was created by her, where you can say the fire element began to become denser and denser, naturally she could control those fire elements easily.
At this time not only her, those other Fighters were also doing the same thing as they were using their full power to kill as many monsters as they could and naturally all of them wanted to kill the Boss monster. On the other hand they also needed to give the time to the healing team to heal those seriously injured Warriors who could have died until now but fortunately they were able to survive even facing that many Monsters.
