Hong Yu made his move.
With a thunderous palm strike, countless black mists suddenly appeared around the moment it was executed.
This black mist was not mere demonic intent but something even more sinister and evil.
As the black mist enveloped them, the palm struck forth, causing countless onlookers to feel a chill in their hearts as if they had fallen into immense fear.
"Purgatory Demon Palm!"
As the palm was executed, Bai Xuan's face changed beside Chu Fengmian and she said,
"This is Hong Yu's ultimate technique. It is said that he once had a great adventure in the Void Sea, where he learned the Purgatory Demon Technique. This technique even surpasses the capabilities of the Eternal Demon Domain, terrifying to the extreme. Once executed, it inflicts endless agony, tormenting the victim to death!"
The Purgatory Demon Palm, once it hit a martial artist, would cause boundless suffering.
