"In the sports equipment room of the school, the sound of heavy blows resounded.
Zhang Zi'ang, with boxing gloves on his hands, his biceps bulging, swung his fists vigorously. Over and over, they hammered the punching bag, stirring up tiny plumes of dust.
Su Junxin stood with her arms folded and watched attentively.
"That's enough."
He stopped, turned to her, slightly panting, "Is the speed of my punches still not fast enough?"
She nodded, "You're big, so you meet more resistance. Try to use your momentum to bring your body into play when you swing. The movement shouldn't just be of your arm."
Zhang Zi'ang tried her method and it did work.
"The reason your speed is so high, is it because of your technique in exertion?"
A spark flashed in Su Junxin's eyes.
The reason she could move faster than Zhang Zi'ang was due to her physical improvements after she advanced her superpower.
