Master Vertol's true offense was not bullrushes or charges.
No.
Those were red herrings.
By constantly charging in over and over, he tricked his opponents into believing that he was a Martial Artist who relied on linear momentum to inflict damage with heavy collisions. His systems of thought relied on constantly conditioning his opponents to be wary of his bullrushes while writing them off as his sole offense.
It was a lie.
He grinned as the two Martial Masters blasted around on the battlefield, grappling with each other.
CLASP!
He pulled Rui into a deeper, deadlier embrace, using all the power he was able to muster in his arms and legs. By further pulling him in, he also subjected Rui to the Yin-Yang Shield, which had now become a full-contact battering ram.
BOOOM!!!
"Rgh!" Rui grimaced as he experienced the full power of Yin-Yang Shield over longer periods of time.
