In Jin Yong's martial arts novels, the Star Absorbing Technique and the Power Absorbing Technique were both well-known martial arts secret manuals, but the author did not explicitly state that they were the same book. Therefore, the specific differences between them still existed in the plot and the words of the characters in the novel, not in the secret manual itself. In some novels, the Star Absorption Technique was described as a method to cultivate into a peerless martial art. The Law of Energy Absorption was a more powerful martial art secret manual that emphasized on absorbing the energy in the universe to increase one's strength. It should be noted that the martial arts secret manuals in Jin Yong's novels were usually kept secret and only specific characters could obtain and learn the martial arts in them. Therefore, we are unable to determine whether there is a real difference between the two secret manuals or whether they have been spread.
