After ten years of sweeping the streets, he once joined the military. The master's words before his death, "Punches are not for punching, but for delivery," set him on a ten-year path of hard training. From a courier to a martial arts master, he has broken his ribs and injured his internal organs, and he will never stop kneeling. There is no flying sword to cultivate immortality, only the stance at four o'clock in the morning, and the echo of someone catching the punch when it is handed out.
