"HAHAHAHAHAHAHAHAHAH." Nathaniel laughed while he killed the thaids, looking like a maniac intoxicated by the feeling of taking other creatures' lives.
The other students watched him going on a rampage with fear and disgust written all over their faces, not because they thought it was wrong to kill Thaids or because his actions were unjustified but simply because it was not normal to enjoy killing, despite doing so with monsters.
Besides, as the students watched Nathaniel fight, they only saw themselves as weaklings in comparison, and this made them feel vulnerable.
Nathaniel's strength came not only from his brain crystal power; no. It was he who was that powerful. The precise control over his body, the perfect execution of every movement. He could do things that others couldn't even imagine.
However, the students weren't only watching. They, too, were killing thaids left and right, or else they would have made him angry, and they didn't want to see that happen.
