Li Changfeng thought of this, and his eyes were suddenly filled with fear.
Although the fear and apprehension were fleeting, Su Yu still caught them.
Su Yu thought to himself, "Fear me? Why would the Deputy Corps Commander of the War City fear me?"
Su Yu quickly recalled Li Changfeng's behavior since entering the Mechanical Hall and immediately realized that Li Changfeng's fear of him seemed to have started from the moment he entered the Mechanical Hall.
Moreover, that fear was not of Su Yu's power, but of Su Yu himself.
"What do I have on me that is worth fearing..." Su Yu thought for a moment and quickly understood, "Ghost Energy? Could it be that Li Changfeng can sense the aura of Ghost Energy on me?"
During the nearly month-long battle with the Brutality clone, Su Yu's entire body had been immersed in Ghost Energy, and the Fighter's Adaptability also allowed Su Yu's body to fully adapt to it.
