Gao Wu: You Can Become Stronger by Slapping Your Face

Ning Wu, who was originally an ordinary member of the Demon City High School, had extremely outstanding physical statistics. But in order to become stronger, he insisted on boxing for an hour every morning. His classmates all laughed at him: "What's the use of boxing for an hour every morning? It's useless." But what they don't know is that Ning Wu has awakened the face-slapping system, and he can become stronger by slapping others in the face. When champion students from other schools came to block the door, no one dared to challenge. Only he went up and punched the opponent into the ground. When everyone was stunned, Ning Wu left a light sentence: "Very good, I can become stronger again."
