Liu Ruyan's heart was in turmoil.

The Thunder Tribulation Pearl, a devastating weapon of war, was priceless and unattainable!

The creation of this pearl was extremely difficult. Only when a cultivator reached the Core Formation Stage and attracted the Heavenly Tribulation, with a great divine ability user nearby to condense the tribulation lightning into a single point using supreme artifact refining techniques, could it be formed.

Such stringent conditions made mass production of the Thunder Tribulation Pearl impossible; each use meant one less in existence.
