Thunder Cliff is no ordinary place!
It is said that long ago, the Holy Ancestor summoned the Nine Heavens Thunderbolt down from the sky, specifically for his own body refining.
The Nine Heavens Thunderbolt is the most violent thunderbolt in the world. To use it for body refining means one's physique has reached an incomparable level of strength.
Later, the Holy Ancestor succeeded in refining his physique.
But that place has always had the Nine Heavens Thunderbolt falling.
Over time, it formed the terrifying spectacle known as Thunder Cliff.
Initially, the Holy Ancestor left Thunder Cliff with good intentions.
Hoping to use it for refining the physiques of others.
But the Nine Heavens Thunderbolt is too overpowering, and apart from the Holy Ancestor and the Immortal Lord, no one else could endure it.
Some even forced themselves to withstand the thunderbolt's might, only to end up with their souls scattered.
One could say, the Nine Heavens Thunderbolt is that domineering.
