"Time's up."
Half an hour passed quickly, and Yang Jian took note of the time. As soon as it was up, he immediately spoke up.
It wasn't that he cared about one or two minutes, what he cared about was that the longer Wang Xiaoming researched, the more reliant he would become on the people-skin paper. Once he felt that the benefits brought by the people-skin paper far outweighed the cost, there was a chance that Wang Xiaoming would forcefully keep it, regardless of the consequences.
His words brought Wang Xiaoming, who was sitting not far away on the ground, back to his senses. He looked up and then said, "The method you use to control the fierce ghosts came from this?"
"What did it tell you?" Yang Jian asked.
"Everything I wanted to know."
Wang Xiaoming slowly closed the people-skin paper: "It's indeed very special. I've never encountered a supernatural item like this people-skin paper."
