Just after Elder Yu flew into the mountain valley, a voice came through.
"It's now, take your positions!"
Upon hearing this, Zhou Yu and the other three immediately soared into the air and occupied the four corners, as Elder Yu had arranged earlier.
Soon after, Elder Yu's voice echoed once more.
"Now, please channel your Divine Power into the Formation."
Zhou Yu immediately channeled the Heavenly Punishment Divine Thunder into the formation before him.
Meanwhile, the other three also channeled their Gold and Wood attribute powers.
For a time, the valley was bathed in multicolored radiance.
These lights all gathered high in the sky, forming a massive cloud formation centered on Elder Yu.
Elder Yu continued to deploy unknown Techniques.
The clouds rolled continuously.
Soon, rumbling thunder erupted.
Seeing this, Zhou Yu's pupils shrank sharply.
"This is..."
At this moment, startled voices came from the others nearby.
"Heavenly Tribulation?"
