The abyss beneath the cliff seemed bottomless, as the Nine Heavens Mysterious Crown fell freely, only touching the base after a long time.
In the midst of golden light flashing, one could see that at the bottom of the abyss was surprisingly a rather small Thunder Pool, where the Thunder Element had condensed into a liquid, resembling a pond.
However, this pond was no ordinary pond, for every drop of water contained terrifying and domineering Thunder Power, the most dominating and violent force under the heavens.
Even in emptiness, this Thunder Pool would not remain calm, let alone now that an uninvited guest had suddenly arrived?
"Boom~"
The Thunder Pool erupted instantly!
A ladle of cold water could cause a previously calm pot of boiling oil to explode.
The arrival of the Nine Heavens Mysterious Crown in the Thunder Pool had the same effect; perhaps for centuries, or even millennia, nothing had ever entered this practically hidden underground Thunder Pool.
