The Heavy Water Lightning Bead was forged by experts proficient in the Laws of Water and were formed using three layers of Heavy Water. While it was a disposable treasure, it was extremely powerful. If one were to be struck by one bead, even a mid-stage Perfected Immortal might not be able to escape unscathed.
There was a black bead about the size of a longan, and there was a hint of black mist lingering on the surface of the bead, making it look rather mundane and unassuming. However, there was no hint of any special aura leaking from it, making it difficult to tell just how deep it was.
Hundreds of purplish-blue lightning bolts that were over a thousand feet in length emerged from within, emitting crackling sounds. The lightning whips looked like they were brandished by the gods themselves, lashing out in all directions, exuding a frightening power of law. It was condensed from heavy water, and their penetrative power was astonishing.
