In this chapter, Hyeon explains his ability to use the law of nature to his advantage. He explains that he fell ill four years ago, and while he was recovering, he began to feel the "energy of nature." He met Lee, who was able to transfer the energy to his own strength, and he learned how to do so by studying Lee's books. Hyeon tells his father that he is exaggerating, but that Lee is also exaggerating. He says that he has heard of taoist and xian techniques, which are similar to the laws of nature, but unlike them, they do not directly use nature's energy.
