At this moment, the thunderous explosions erupting within Upper Firmament Heaven's formation transmitted all the way into Celestial Xia's formation mechanisms. Even here at the passage between the two realms, wave after wave of impact blasts could be felt sweeping across their faces. Dazzling light flashed continuously, casting every cultivator present in its radiance.
What had been dropped into the formation this time were precisely the Formation-Breaking Thunder Pearls.
Daoist You had previously proposed that disrupting Upper Firmament Heaven's formation veins would require at least ten thousand thunder pearls. This time, the Profound Court had given him a pleasant surprise.
Not ten thousand, but a full three million pearls had been assembled. Though short of ten million, it still left him feeling abundantly supplied.
Every one of these thunder pearls had passed through the hands of a Profound Venerable, refined and evolved within identical cauldrons.
Even the refining methods had been exactly the same. With the Profound Venerables' exquisite mastery of artifact refinement, all the thunder pearls could be made so alike as to be virtually identical.
Throughout the preceding series of fierce assaults, Daoist You had relied on his experience to roughly determine the locations of several formation mechanism veins on the other side.
But the fewer thunder pearls there were, the more he had to rely upon his own judgment.

This attack did not require every thunder pearl to land
