Wu Li took a step forward, and his body reacted naturally.
Snap!
His buttocks clenched, and the muscles in his waist stretched so tight that his clothes bulged noticeably, like a startled python violently rushing to his back.
In an instant, Wu Li's entire spine was also driven by the explosion in his buttocks, arching and surging, the large muscles on his back bulging, even stronger than when Gao Zheng had fully exerted his Eagle Spread Wings!
With that transfer of energy, Wu Li's whole body was explosive, each muscle like a barrel of gunpowder, bursting instantly!
"Rotating the legs, the buttocks clench," this indicated that the Xingyi Fist Power had reached all over the body, as round and unified as one, having cultivated the large buttocks.
As the saying goes, "Lift from the gut, power reaching the extremities, rotate the legs, the buttocks meat intersects!"
