William couldn't be more familiar with this move.
However, when she was used by the matriarch, William's mind was in a state of chaos.
He would never have imagined why Britney would use the 'Nine Tranquility Skills'!
"This is impossible!"
The 'Nine Tranquility Skills' was one of the moves recorded in the 'The Scripture of Tranquility'!
This was his grandfather's creation.
Not to mention The Lu Family of North Forest City, even The Lu Family of North Lake City, there was probably no one else who could use it!
However, the matriarch had used it!
In addition, with the matriarch's level of cultivation, the power of her use of the Water-swirling Kick was completely different from William's!
A thought flashed through William's mind and he knew that he could not avoid it completely.
With a bang, his body slammed into a pillar behind him!
William's eyes were fixed on the matriarch.
The matriarch had withdrawn her strength at the final moment.
