Despite being Novice Eye Kings, the strength of Sigrid and Aren was very high for Rank 3 life forms. They were able to face Peak Rank 3 life forms without a problem, even if they had powerful bloodlines or expensive armament.
However, there was dissatisfaction in Ezequiel's eyes as he analyzed the duo, especially when he saw how complacent they were with their new power.
Sigrid and Aren were accustomed to the cold attitude of their trainer, and they remained quiet as they waited for his instructions.
Despite the hellish training they had to endure, there was no resentment in the heart of the Eye Holders. One of the reasons is that they were mature enough to understand that power is absolute, and getting angry was not a luxury they could give themselves when they faced the Supreme Neo-Demon. Even now, they felt the difference between their power and Ezequiel's was so large that he could kill them with a single attack.
