Aiden didn't want to kill someone in such a place and cause trouble for himself. His marksmanship wasn't so precise that he could ensure not hitting a vital point under these circumstances, but he was able to shoot without worry because he was confident he could heal the person—at least he wouldn't accidentally blow someone's head off while aiming for their legs.
"Ah! Aaahhh!!" Tabus was still howling until a few seconds passed and he found the pain in his leg had mostly disappeared. "Eh?"
He touched the spot where he'd been shot. There was no sign of blood or a wound, not to mention the hole in his pants had vanished without a trace.
It was good that the fatal wound was gone, but it sent shivers down his spine. He looked fearfully at the gun-toting "woman" who had barged into his tent. This creepy healing magic was obviously her doing.
