On the day Chu Yan was expelled from the provincial team, an old injury to his Dantian recurred, and the doctor said he could not do strenuous exercise in his life. Three years later, while delivering food, he passed by an alley and was punched in the stomach. A band of light that only he could see suddenly appeared in front of him. The man who hit him had a line of words floating above his head: Bajiquan, proficiency level 70%. Ruan Mingyuan was squatting in the waste pile and eating steamed buns. When he saw Chu Yan squatting on the ground and covering his stomach, laughing, the old man threw the steamed buns away and said, boy, you are enlightened. That night Chu Yan was pulled into the underground boxing ring. Above the head of his opponent in the first match was written: Muay Thai, proficiency level 92%. Ruan Mingyuan leaned outside the iron cage and shouted, "If you can't beat him, run away. If you can't run, then get punched. After this meal, you can see where his next punch will go." After Chu Yan had three ribs broken, he really saw it.
