I Became the Supreme Martial Arts Master by Brushing up My Proficiency.

When I woke up, I became an orphan in the martial arts world, and was bound to a strange system. When someone else's system gives you magical secrets, my system will only prompt: "Basic boxing proficiency +1." I desperately thought that I would only be a gangster for the rest of my life. Until that day, when my enemies slaughtered the escort agency, I silently performed the basic punches for the 36,000th time. The fist wind is like a dragon, and the master falls.
