Mo Fan was testing his limits, but the reason why limits were called limits was because they couldn't be broken easily. Improving one's mechanics and awareness wasn't like farming for equipment in-game. You couldn't just get lucky and suddenly improve your strength with a piece of powerful equipment. These were things that were improved day by day, training and training, slowly accumulating real battle experience. If you wanted to break through your limits, it was the same. It wasn't as simple as one day becoming passionate about it, deciding to work hard and achieving a breakthrough.
Mo Fan was continuously testing his limits with disregard for everything else. He really was in a state he had never reached before in training. However, breaking through one's limits wasn't like farming equipment. It wasn't as if once you accomplished it everything was good. An abrupt breakthrough was one thing, but mastering it was another. In other words, you had to accumulate experience bit by bit.
