Alier's Strength

As the barrier's source was about to fade from the constant bombardment of dozens of knights from outside, the assailants were getting more desperate inside. 

While Alier was chasing the leader of the ambushers like a dog without a leash, throwing spikes and spears of ice, using waves of his Elemental Essence to scare the heart out of the assailant's leader, and the leader responded by using his fire elemental essence, countering and dodging although just barely—the other ambushers were starting to push back the exhausted knights. 

The knights, despite being strong, brave, and well-coordinated, could no longer fight on as they were covered with wounds all over their bodies, but seeing that they had no choice but to fight to their last breath, they were pushing the most absolute limits of their physic and consciousness.
