"You... you know?"
Wang Zhan was stupefied, looking at the Old Man with an incredulous expression.
"Why? Why can't I know?"
The Old Man glanced at Wang Zhan with an expression that seemed to say he was looking at a fool. He lifted his finger, gently shaking it. His skin gradually changed from its normal color to black. "Isn't it like this?"
"Yes, yes, yes!"
Wang Zhan nodded his head furiously in agreement.
The Old Man's finger was much darker than when he himself had used Dark Energy. When he killed the Sky Eagle just now, his fist had also changed color, but in a very limited way, only slightly grayish. Compared to the Old Man's pure black, there was simply no comparison.
"How did you do this?"
