Zhang Zhiping rummaged through the descriptions of the two worlds for the entrance and the hole, and threw away those mysterious words, and he summed up the three characteristics of the hallway: 1. It can be in any position inside and outside the body, 2. It can help the body absorb aura, 3. Different cultivation methods, the position of the entrance is also different, and the position of the entrance is about the same for practitioners of the same kind of exercise.

Zhang Zhiping felt that the mystery of the entrance was hidden in the second and third features, so he decided to experiment with it. He didn't dare to experiment on his body at random, but with the help of the Five Visceral Gods, he used spiritual power to simulate a static and perfect meridian acupoint model in front of his eyes.

Looking at the static meridian model in front of him, Zhang Zhiping first controlled the spiritual power lines of the twelve canons to gradually run at a certain speed, without the slightest reaction, and then gradually increased the number of running spiritual power lines, and the spiritual power operated according to a complex running line, with the completion of a weekly operation, he suddenly found that when the spiritual power was running, there were spiritual power fluctuations somewhere outside the model.

Zhang Zhiping didn't dare to relax, and repeatedly followed this route, and the spiritual power fluctuations no longer flashed away, but continued to appear in a certain position, in this position, there was a small spiritual power gradually gathered, until it reached a certain level and there was no longer a reaction, he thought about it, and first called this position the spiritual power convergence point.

Zhang Zhiping stopped, and then began to change the number of spiritual power running lines, and the position of the spiritual power convergence point also changed, constantly moving inside and outside the model; In the process, we also encountered some other problems, such as conflicting running paths, too many lines that made it impossible to complete the weekly operation, and so on.

It took three days, lasted hundreds of experiments, and after repeated confirmations, he came to a precise conclusion: as the spiritual power lines completed a week, a corresponding spiritual power convergence point would be generated somewhere outside this operation system, and the location of this spiritual power convergence point would be different with the number of running lines and the different operation paths.

Zhang Zhiping felt that he had found part of the principle of the entrance, but this spiritual power gathering point never had a connection with the model. He thought for a moment, and then chose a spiritual power to run unchanged every day, speeding up the operation. As the speed of operation accelerated, more and more spiritual power was gathered at that spiritual power gathering point, and finally it seemed to break through a threshold, and a stream of spiritual energy instantly dispersed the spiritual power model, turning into countless spiritual power and disappearing in front of his eyes.

Zhang Zhiping felt that he had found the truth, and immediately simulated the meridian model again, repeating the experiment just now, and the model was broken again. Then he changed the operation of different spiritual power lines to speed up the operation of spiritual power, and found that whenever a threshold was reached, the model would be broken by an external force. This threshold varies depending on the path and the number of lines, but in general, the higher the number of lines, the faster it needs to be moved, and the more spiritual power it has to break through the model.

Zhang Zhiping immediately thought that this spiritual power gathering point was the entrance he was looking for, because it met all the characteristics of the entrance hall. Zhang Zhiping didn't dare to be careless, and repeatedly conducted experiments according to different spiritual power operation methods, although there were all kinds of problems in the middle, but as long as the experiment was completed, it would inevitably be a model of gathering spiritual power in the end.

After ten days of experiments, Zhang Zhiping repeatedly verified, and finally combined with the knowledge of the previous life, he finally came to a popular conclusion:

When the internal force and mana complete the operation of the Zhou Tian in the meridians, just like a whirlpool or tornado, a spiritual vacuum position will be generated in the center; this vacuum position will have an attraction to the rich aura of the outside world, and produce a spiritual power gathering point in the outside world, that is, a hole in the entrance; with the number and difference of the internal force or mana running meridians, the position of the vacuum point is also different, and the position of the hole produced by the entrance is also different; when the speed of operation is continuously accelerated, the vacuum point and the hole of the entrance will be connected, so as to complete the process of absorbing the spiritual energy of the outside world.

After Zhang Zhiping came to this conclusion, he immediately started experiments on himself. As a cultivator's cultivation improves, the speed of mana in the body will continue to increase until it reaches a fixed value. In this way, both refining mana and casting spells will speed up, so few people will slow down their mana. Zhang Zhiping's current experiment is to slow down the speed of his mana, and at the same time pay attention to the changes in his entrance. The speed of mana was getting slower and slower, until it was not as fast as the speed of his internal force when he was a mortal, Zhang Zhiping immediately discovered that his entrance was gone!

"Hahaha······" After demonstrating his research, Zhang Zhiping felt that his whole body was suddenly filled with a sense of satisfaction, which made him laugh. The feeling of studying the mysteries of the practice and being able to understand its principles was so satisfying! He was so excited that he couldn't calm down for half a day, and he even wanted to go out and run a few laps to express his excitement. Fortunately, Zhang Zhiping is still rational and did not do such a stupid thing.

With the theory, Zhang Zhiping immediately began to solve his own problems.

Since there is no spiritual root, the spiritual power absorbed by the entrance is all five attributes, for others, this kind of spiritual energy is too mixed, and the mana cultivated is not of great use, which is also one of the reasons why the cultivation of innate martial artists without spiritual roots is slow. But for Zhang Zhiping, as soon as these mana entered the dantian, they would be separated by the five visceral gods, which was the most suitable aura for his cultivation, so he would waste so much strength to try his best to absorb this mixed aura. If the rest of the monks knew about Zhang Zhiping's behavior, I am afraid that they would want to kill him directly.

But now the problem is back to the beginning, that is, the entrance hall absorbs too little spiritual power.

Zhang Zhiping is still practicing "Ning Yuan Jue" now. Condensing Yuan Jue is one of the most orthodox immortal cultivation techniques, and its principle is to make the mana run in a way that mimics the natural operation of the life vitality of a person since birth. The meridians are not unique to immortal cultivators, everyone has meridians, and in mortal bodies, there will also be life vitality running naturally in the meridians, and once the meridians are blocked, people will get sick. Life energy is a special existence, it is even more ethereal than aura, but it is known that it is the foundation of life and can support the activities of life. However, it is not that there is no way to use it, the internal force is condensed by a large amount of life vitality, and among immortal cultivators, there are also places that involve the use of life vitality.

"Ning Yuan Jue" will absorb the aura to imitate the original Yuan Qi running veins to operate, in the process will continue to wash the meridians around the body, many small meridians are naturally washed away in this way, this is the reason why Ning Yuan Jue can easily transfer to other exercises.

But the most natural is not the best, let alone the fastest, otherwise there would not be so many artificial weapons that can override nature. Relying on the natural flushing of Ning Yuan Jue, the meridians in Zhang Zhiping's body didn't know when they would all be opened, let alone wanting to absorb spiritual power through the entrance to cultivate. Now the spiritual power he absorbed in a day at the entrance was not comparable to the spiritual power he absorbed in a quarter of an hour with his spiritual root, so his cultivation method had to be changed.

However, Ning Yuan Jue has a characteristic, that is, it can gradually involve the operation of all meridians, and will not focus on a certain attribute, unlike many specific spiritual root exercises, which will focus on the operation of the meridians that are consistent with the attributes of the spiritual root, which must be utilized, Zhang Zhiping does not want to have the problem of imbalance in the five elements after some research.

Zhang Zhiping was stunned and looked at the model of Zhang Xu's biblical veins and acupoints in front of him, this was the most perfect model he had ever seen, so according to his previous theory that the more meridians he operated, the more aura he absorbed, if he could make use of all the meridians in it, the aura absorbed by the hallway should be enough to meet his cultivation needs for the Qi Cultivation Realm. And at present, the exercises that can involve all the meridians in this model, as far as he knows, are only Ning Yuan Jue.

But Zhang Zhiping will never be like before, just relying on the natural flushing of Ning Yuan Jue to open up the meridians, otherwise he really doesn't know when he will be able to penetrate the meridians of the whole body. Now that he has this perfect meridian model, he can follow the map to open up all the remaining meridians.

It's just that the cultivation speed of Ning Yuan Jue is still too slow, and the utilization rate of mana is also very low. Zhang Zhiping couldn't help but have an idea in his heart: based on this perfect meridian acupoint model, Ning Yuan Jue and Five Visceral Gods, create a technique that can be cultivated at the same time with the help of the Xuanguan One Trick and the Spiritual Root.

Due to the perfection of the meridian model, which involves the operation of all meridians, I can also integrate the exercises I have seen into it in the future to further improve the operation and efficiency of mana.

Yes, just do it, even the name is ready-made, just like "Void Breath Technique", since it is all from Zhang Xusheng, the new exercise method is called "Shengyuan Gong".
