Proof

Ning arrived at a row of prison cells, with people inside that had lost all hope. He walked past them, looking through everyone.

"You brought me here to check to see if there is a Spirit on them?" he asked.

"Yes," the young guard said. "Not necessarily because they're prisoners, but because they are the most amount of people I could get to immediately. And I want to see your powers firsthand."

"I could've just shown you my powers," Ning said. "I can create a sort of barrier."

"But that doesn't tell me if you are a Spirit Detective or not," the young man said. "That only tells me that you are a Spirit Awakener."

Ning nodded. "I see. I understand your point," he said. "Let me check if I can find someone."

Ning walked on ahead, looking through the prisoners until one caught his eyes. It was a short man, in his late 30s, sitting around on the bed with a mattress that could barely be called one.
