After sneaking some drops of the herb from the stone into his father's medicines, the sixth level body refinement has healed his injury. This means that he can now drink the herb directly. This is his only chance to beat Lin-hong in the upcoming tournament, which is three months away. The herb has a powerful healing effect on the meridians of the body, which makes the herb even worse than a hot pepper. The next few days, he drinks the herb and trains in martial arts. He is surprised to find that he has reached the fifth level. He feels that he is missing something in his body, and this makes him unable to progress any further. The only way he can break through the bottleneck is to face a life-and-death situation.
