After carefully probing with the Human Bone Staff, he sensed a faint spiritual power reaction on Fu Qingzhu's body, but it was already very weak.
Based on his experience, Yang Xiao determined that someone had used a Magic Artifact to drain Fu Qingzhu's spiritual power and trap him, which was why his body was in this state.
This tactic was indeed vicious. If the opponent could do this to Fu Qingzhu, then killing him would be a simple matter, but the opponent did not do so.
Yang Xiao could think of two reasons for this: First, the opponent wanted Fu Qingzhu to die ambiguously, after all, he was the vice president of the United Federation and a senior official of the Three-party Action Bureau, with certain social influence, killing him directly would be unwise.
The second reason, which Yang Xiao found more plausible, was that the opponent wanted to extract secrets from Fu Qingzhu's mouth.
