The Strongest Villain, Dark Xi Nian!

"What?!" Superman was immediately startled, realizing something was seriously wrong. "Xi Nian?" Seeing Xi Nian suddenly close his eyes, Superman did not hesitate. With all his strength, he struck at the black ring Xi Nian was wearing! Bang!! The air exploded. Superman Clark's fist, carrying the force of ten thousand tons, was firmly caught in Xi Nian's upturned, outstretched right palm. "Xi Nian, you..." Superman Clark's eyes widened in shock and uncertainty. In his trembling azure eyes was reflected Xi Nian's figure.
