Lightning flashed and thunder roared, as one bolt of heavenly tribulation after another struck down, the blinding light of the thunder engulfing the entire valley. Shockwaves billowed, turning this part of the world into a sea of thunder.
Shen Long's gaze was fixed on the thunderclouds high above, his expression grave.
The Gold-Winged Windroc's assault on the fourth level had already summoned two bolts of Tricolor Divine Thunder. Now, transformed into the Thunder Roc to assault the fifth level, it was uncertain which kind of heavenly tribulation would be summoned.
Time ticked away, with each bolt of heavenly tribulation growing larger and the lightning becoming even more blinding.
After half an hour, the thunderclouds churned and surged, giving rise to arcs of blue, red, green, and gold electricity.
"Four bolts of Four-Colored Divine Lightning!"
Shen Long's brow furrowed.
