In this chapter, we learn that the elixir can even double the effectiveness of martial arts training. In other words, the higher the level of the elixir, the more effective the training becomes. So, if you're looking for a way to get the most out of your martial arts lessons, you might want to consider taking in some of the "high-level elixirs" like red ginseng, which can double the amount of training you can do in a day. In fact, red ginseng can even "level someone up" and "bring the dead back" , according to the legends. But red ginseng isn't the only thing that can help you train: perseverance and hard work are also very important. And if you don't work hard, you'll never be able to get to the next level of training, which is called "penetrating fist" .
