"Before teaching you, I'll ask you first." The white-haired old man looked at Huang Yuchen, waved his hand, and signaled him to sit down. After Huang Yuchen sat opposite him, the white-haired old man continued: "What do you know about the strongest attack method?"

When Huang Yuchen heard this, he thought carefully in his mind, thinking about the classics he had read and the things he had experienced. If there is only one who has the strongest attack power.

"Thunder Fighting Qi." Huang Yuchen blurted out. Although he had never fought with the practitioners of Thunder Fighting Qi, and had never seen anyone really use Thunder Fighting Qi, he knew that this kind of Fighting Qi is called the strongest in the world, extremely powerful and fastest among all Fighting Qi.

The legend of Duanmu Huai of Chihong Sect is said to be a cultivator of Thunder Fighting Qi. However, Huang Yuchen had seen Duanmu Huai several times, but he had never seen him use any Thunder Fighting Qi. All the senior leaders of the Chihong Sect, including Duanmu Huai, have never used Thunder Fighting Qi. This also confused Huang Yuchen, but he had never asked anyone to ask.

"Hahaha." The old man with white hair smiled lightly when he heard this, and then stretched out a hand. A pure white energy body quickly surged out of his palm. Huang Yuchen could tell at a glance that this was the most common white energy crystal in his body. Using this pure energy, he could refine various pure and simple elements. This was how the pure fire attribute elements in Huang Yuchen's body came from.

However, the situation that happened the next moment made Huang Yuchen stunned. The white energy on the white-haired old man's hand quickly transformed into several different areas. Each area showed a different color, divided into red, orange, blue, brown and a more pure white. Huang Yuchen could see that this was different from the other five energy sources, which Huang Yuchen knew. The pure elemental Dou Qi represented: fire, wind, water, wind, earth and thunder. These are the five most pure Dou Qi known to be cultivated by people. Huang Yuchen can also do it, but it requires the assistance of the formation. After refining a Dou Qi, a large amount of energy will be consumed, and most of the remaining energy is released by Huang Yuchen.

Now if Huang Yuchen wanted to refine these five energy types, there would be no less than twenty formations to be portrayed. These formations would probably cover his entire body, which would be a very time-consuming task, but the white-haired old man did it casually.

Huang Yuchen looked at the five kinds of energy in the hands of the white-haired old man and stared blankly. He knew that the gap was very big with the white-haired old man. Only now did he know that the gap was not an ordinary big one.

"These are the five kinds of energy you can cultivate." The old man from the white-haired whispered: "The combination of these five kinds of energy is called the power of yang, which is the fighting spirit in your mouth. However, the energy that ordinary people practice is not so pure, and some impurities will inevitably be absorbed in the process of absorbing natural power. It is precisely the influence of these impurities. People with good qualifications have different levels of cultivation. There is really no one who can cultivate complete yang power to the level of the venerable level in the entire range of prayer."

"No of the Venerables you see has cultivated pure energy. They all used other methods, that is, the help of the instant walker, to force them to upgrade to the level of the Venerable combat power. The energy in their bodies is not pure, and there is no possibility of practicing to the Supreme Master." The white-haired old man said softly, his fingers moved slightly, and several balls of energy on his palm slowly turned in his palm, and slowly formed a vortex in his palm. Slowly, the vortex evolved into a new star wheel, which made Huang Yuchen stunned.

Now Huang Yuchen can't say a word. The ability shown by the old man has exceeded his imagination. The star wheel can actually be formed in his hands, which is beyond his cognition.

"You should know that the natural powers in the world are very complex. They not only contain five kinds of yang forces, but also the corresponding five kinds of yin forces. In addition to these ten kinds of energy that can be used, there are some other impurities, which must be completely eliminated."

The old man said, stretching out his other hand. A black mist suddenly appeared in the palm of the hand, just like the black mist that Huang Yuchen had seen before. This black is very pure black, as if it could absorb all the light around him. Similarly, the old man's fingers moved lightly, and the black mist changed rapidly, transforming into five different areas in his hand, showing different colors, namely: green, light black, dark black, blue and an indescribable color that he had never seen before. This color is a bit blue but also a bit black, which is indescribable.

Huang Yuchen had never seen these energy bodies, and it was even more impossible to know their classification. He just stared at the palm of the white-haired old man in a daze, and looked at these balls of energy that he had never seen before, and felt shocked in his heart.

The original world was really much more complicated than he thought. Everything he had learned before was just the tip of the iceberg of this world.

"These should be something you have not touched before. They are the five types of energy that constitute the power of Yin. In your world, there are only a very small number of people who practice one of them. This is this." As he said that, the old man with white hair moved his divine thoughts, and the dark black mist in his hand floated out, staying in the air between the two, and slowly turning.

"This is a dead energy, an energy that will naturally be produced after a person dies. It is also the most powerful of the Yin power, and it is also the most difficult to practice." The white-haired old man explained softly: "In your world, those who practice this energy are called dead cultivation. Once discovered by others, they will encounter a catastrophe. After all, practicing this kind of fighting energy requires absorbing the dead energy of people, and the dead energy is the most intense when a person dies."

Huang Yuchen stared at the pure black energy in front of him, and a faint chill came from the fog, as if it was coming from the bottom of his heart, which made him shudder involuntarily.

"Apart from the dead energy, the other four types of energy are not easy to understand." As he said that, the old man with white hair released the other four fogs, making them into a row, all floating in front of Huang Yuchen's eyes, and said: "This energy that looks a little green, I am used to calling it poison. This poison is not a poison in the surface meaning, but a mentality."

"Mentality?" Huang Yuchen was stunned when he heard this. Mentality? It means that human hearts are evil. How to cultivate a mentality? How can one be used to fight against the enemy?

"Yes, it's mentality." The old man with a white-haired smiled and said, "The power of Yin, except for the dead energy you see, is the entity, the other four are mentality. The green one is poison, the light black one is anger, and the blue one is desire. The last one is the foundation of the human heart, and I call it the self."

After hearing the old man with white hair, Huang Yuchen was confused and didn't understand at all. How could the emotions in these people be used as energy to practice?

"It's normal for you to be confused in your heart." The old man said, waved his hand and recalled the five energy groups in front of him. Another star wheel was transformed into a black body, which was completely different from the bright color of the star wheel before. Then the old man slowly closed the two star wheels and traveled a new star wheel. The black and white in the star wheel were interspersed. Huang Yuchen looked at it and felt it looked like the sky at night, and he couldn't help but feel shocked again.

"This is the star wheel that has been completed in cultivation. How about it compared to yours?" The old man with the white-haired dragged the star wheel in his hand and approached Huang Yuchen for a look. Huang Yuchen looked carefully, and compared it with the star wheel on his chest, and replied, "It feels... more real."

"Haha, you kid, have a good understanding." The old man with white hair smiled. This time he seemed to be smiling from the bottom of his heart. Huang Yuchen could feel the feeling of being happy. Obviously, he was very satisfied with Huang Yuchen's answer.

Then, the old man with white hair took back the entire star cluster. When the colorful star cluster disappeared from his eyes, Huang Yuchen suddenly felt a sense of loss in his heart. He felt that the star cluster seemed to be the ultimate he was pursuing in his heart. A strong desire to get the power of this star cluster appeared in his heart, but fortunately, he was able to suppress this impulse and did nothing out of the ordinary.

"I know exactly what you feel now." The white-haired old man looked at Huang Yuchen and said with a smile: "But your ability to suppress it also proves that I am not wrong with you. You are indeed a good seedling. In time, you will definitely be able to cultivate your own complete star wheel."

"Senior." Huang Yuchen suppressed the desire in his heart, and then looked at the white-haired old man, and many bloodshots appeared in his eyes. This situation had only happened in extreme depression before, but now it appeared in a very short period of time: "How should the power of Yin be practiced?"

"The cultivation of Yin power is divided into two steps. The first is the cultivation of dead energy." The white-haired old man explained with a smile: "The cultivation of dead energy is very simple. You only need to absorb the dead energy and enter the existing star wheel. The star wheel will automatically absorb the dead energy and convert it into energy you can use. However, because of the special nature of dead energy, before practicing dead energy, you first need to learn how to cultivate the Yang power and merge the energy of the five kinds of Yang powers to offset the corrosion of dead energy on your body."

"Only when you do this, you can consider practicing the other four kinds of Yin powers. This will be a long process." The white-haired old man said softly, and Huang Yuchen listened very seriously at this moment.

"I call the four Yin powers besides the dead energy, the heart-to-dou Qi." The white-haired old man looked at Huang Yuchen and smiled and said this: "Human emotions are powerful in themselves, but you can't feel them deeply now."
