Let Him Remember My Sandbag-sized Fist

After returning to the park, Xu Cheng went back to the pavilion. He closed his eyes and began recalling the 30 strokes that old man had just practiced. It was indeed unpredictable and unbelievable. To be honest, this was the first time Xu Cheng couldn't see through a person's movements. Regarding those fist strike techniques, no matter how Xu Cheng used his ultrasonic ability to capture the strikes, he could at most see 12 strokes.

After opening his eyes, Xu Cheng tried to practice the 12 strokes he already memorized. After practicing it once, he shook his head. "No, not fast enough still."
