Yman finally furrowed.
Although he was successful in restoring the external parts and internal organs' conditions, it seemed some of his internal parts showed Malfunction status.
He wondered what was lacking.
Yman pondered. But then he noticed that although the body was already in good condition, the blood hadn't yet circulated throughout the body. So in this case, the reason for it was the heart. No wonder it showed (Mal) status.
Since the heart has malfunctioned, it was only natural for the other parts to not function as well.
To make the blood circulate in the person's body, the heart needs to function first. And to make it function again, that was the problem he needed to solve first.
"Hm," Yman pondered. "So it seems I needed to stimulate the heart," Yman muttered. 'Right. The heart needed a stimulus to pump again.' At that moment, he already knew what he needed to do.
