"Yeah, teacher..." Saleen felt rather embarrassed. The way Jason put it made it sound like he was some kind of upstart. Jason relied on his own power and took down a level 11 Vermillion Knight cleanly without using any equipment. Saleen, on the other hand, relied on the powerful Thunder Dragon Blaster.
The power of the Thunder Dragon Blaster had already been tested in the astrology tower. Level 13 defense was practically useless against the equipment, and the Vermillion Knights were only level 11 beings.
Elemental creatures were not humans and did not possess any powerful equipment. They relied solely on their own elemental powers to fight.
