Alex finally stopped hurting from his own fire now that the disorienting buzz was gone. The fire still burned around him, but he controlled the heat from transferring onto himself.
The insect-controlling man looked fully in shock at what he was witnessing, and Alex used this opportunity to burn the insects that were in front of him.
He barely singed the wings off a few insects before the man moved them from harm's way. At the same time, the beetles formed a barrier that stopped the fire from burning them.
The man realized that he was in trouble, so he made the insects start buzzing again, but by that point, Alex had made two small earplugs with his blood which he put into his ears. Without any sound, the buzzing noise could no longer affect him.
He let go of the fire around him and showed his fully unhurt body. His hair was burned off all around his body, but he didn't mind that. He had a pill for that anyway.
