The flames exploded in every direction before they simply stopped moving. Arthur's spiritual powers contained the explosion and made it destroy only the man's arm.
"AHHH!" The man screamed in pain as he fell to the ground. Arthur didn't release the explosion from his arm and waited for it to die down.
It was a bizarre sight as if the man grew an arm of flames. The man begged for mercy, but Arthur didn't know what to do for him.
"Please, it hurts! Take it away! AAAH!"
"You're the one who detonated himself, man." Arthur felt a headache. "What do you think would those people in the shop feel once you pressed the detonator?"
With Arthur cutting away the oxygen from the explosion, the flames were short-lived. However, all that was left was a mangled arm.
"If I heal your arm, your pain receptors might regenerate as well. It will be more painful than now, but you have a chance of using it again."
