Improvement

The woman closed her eyes, grabbing Ning's left arm. She pushed on it, making Ning feel a sharp pain in his arm. Then, she pulled on it. As if extending his arm like a rubber, the army grew as she pulled on it, slowly growing muscle, tissues, ligaments, nerves, bones, and skin.

Ning watched his left arm regenerate in a slow, steady fashion. It had been a long time since he saw it happen this slowly.

When she finally managed to heal his arm, Ning flexed his left arm a bit to see that she had done a perfect job.

"Thank you," Ning said, slowly moving his arm around. His fingers moved just as well and they grasped things just as well. He could fight with a spear again.

"Are you happy?" she asked.

"Yes," Ning said, his smile widening slightly. "This is amazing."

"Good. Now leave my place. I have other people to help too," she said.

"Yes, yes," Ning said. "Thank you for healing my arm, genuinely."

"No problem. Now leave."
