Boom!
At this moment, shockwaves rippled out high up in the skies. An extraordinary Spiritual Energy fluctuation condensed like a storm as a powerful Spiritual Energy pressure enveloped the entire world.
The source of this rumbling Spiritual Energy was a massive black tower. Black flames surged throughout the surface of the tower as it descended down.
The scene was quite a shock and countless individuals watching could not hide the surprise within their eyes.
Even for those who had reached the Heavenly Fusion Stage Middle Phase, this attack was enough to stun them.
On the summit, Mu Kui and Bing Qing had exceptionally solemn expressions and their eyes twitched slightly. From the Spiritual Energy fluctuation in the sky, they could feel a fatal-type of danger.
It was evident that they never expected that Mu Chen and Yang Hong’s battle would be this extreme.
