Bab 591: Smashing his way through

The black Spiritual Energy appeared like a black screen in the sky as it flickered with a cold luster as it soared. Powerful Spiritual Energy pressure swept out as if it was trying to set off a tornado in this region.

Everyone was dumbstruck as they watched the scene before them since they could sense how powerful that black Spiritual Energy was. They found it too hard to believe that Mu Chen could still exhibit such strength even in his current state.

Fang Yun was also looking at the vast and mighty black Spiritual Energy with a little shock in his eyes.

"Damn it!"

Fang Yun heavily clenched his teeth. Originally, he had planned to take action while Mu Chen's state wasn't good and seize his Academy Plaque. However, who could have expected that even after so many battles, Mu Chen could still exhibit such strength?

However, there was no way he could retreat at this point in time.

Boom!
