The Northern Dark Divine Technique and the Power Transformation Technique were two very famous martial arts in Jin Yong's novels. They had different characteristics and cultivation difficulties. The following are their respective characteristics and differences: Northern Dark Divine Technique: The Northern Dark Divine Art was a kind of internal force cultivation method that absorbed the spiritual energy in nature to increase internal force and achieve a powerful effect. It was very difficult to cultivate, and it required a profound martial arts cultivation and a deep foundation of internal energy. During the cultivation process, one had to pay special attention to prevent internal energy from leaking out. The characteristic of the Northern Dark Divine Art was that it could directly increase a person's internal strength, but the amount of spiritual energy absorbed was limited. Once it was consumed, it could not be recovered. Power Transformation Technique: The Power Transformation Technique was a martial art that improved one's martial arts skills by transforming the enemy's internal energy. Its cultivation difficulty was relatively low. One only needed to have a certain level of martial arts cultivation and a deep foundation of internal strength to successfully cultivate it. To cultivate the Power Transformation Technique, one needed to choose the enemy's internal energy to transform and pay attention to choosing the correct internal energy. Otherwise, it might cause internal energy imbalance or side effects. The unique feature of the Power Transformation Technique was that it could transform many different types of internal energy and improve one's martial arts by controlling the flow of internal energy. Star Absorption Technique: The Star Absorbing Technique was a martial art that increased internal strength by absorbing the vitality of others to achieve a powerful effect. It was also very difficult to cultivate. It required profound martial arts cultivation and a deep foundation of internal energy. Moreover, during the cultivation process, one had to pay special attention to prevent internal energy from leaking out. The specialty of the Star Absorbing Technique was that it could directly increase a person's internal energy, but absorbing the vitality of others was very dangerous. If it failed, it could lead to death or internal energy imbalance.
