Yan Lingyun's heart moved, and said, "Then there is Lao Zengzu!"

Bai Qianshan advised: "The exercises are in your heart, and I won't say much, just keep in mind the eight characters of 'tranquility and nothingness, and true qi comes from it'."

Yan Lingyun nodded solemnly, sat with his feet folded, closed his eyes and hung the curtains, his hands were naturally placed on his knees, and gradually entered the realm of "sitting and watching".

The method of cultivating qi in the supreme foundation method flowed through his heart, and he carefully scrutinized it several times, and after calmly mastering it, he began to act according to the law.

First of all, it is a process of refining and refining qi, the heat furnace in the body gives birth to changes, and the surging heat gradually spreads to the whole body under the intentional guidance, rolling and boiling, provoking the essence of the whole body, like smoke and haze, there is a feeling of cloud steaming.

Of course, Yan Lingyun couldn't see it, but he intuitively felt that the flesh and blood of his whole body had turned into a lively and lively tiny individual, spitting out essence one after another. His pores were tightly closed, not missing a trace of essence, and they gathered together into clouds of smoke that floated through his body, and then the clouds of smoke gathered more and more, as if they were being pulled and thrown towards a mysterious origin in his lower abdomen.

This mysterious origin is the "Lower Dantian".

The human body is born with 360 hidden spiritual apertures, which are scattered throughout the body's muscles and veins, corresponding to the number of Zhou Tian. However, there are only three of these three hundred and sixty spiritual apertures, which are well-known to the world, and they are the three major dantians of the upper, middle and lower levels.

The lower dantian, even ordinary people who are not familiar with martial arts also know, because people are alive, pay attention to a dantian qi, this dantian, is the lower dantian in the middle of the lower abdomen, in terms of qi practice, the main small Zhou Tian operation.

Zhongdantian, located in the middle of the human body, the heart socket, also known as the Yellow Court, the main Zhou Tian operation.

Shang Dantian, that is, the entrance, is in the middle of the forehead eyebrow, which is the place where the Yuan Shen begins, and it is also the heavenly palace in the mouth of the immortal cultivators, and the Lord Zhou Tian is complete.

The three major dantians and the three Zhou Tian constitute the three stages of Qi training, first the small Zhou Tian, then the big Zhou Tian, and finally the Zhou Tian Consummation.

Zhou Tian's consummation is only a short transition, when the human body is connected to the two veins, the yin and yang bridge, the entrance is opened, and the five qi are born towards the yuan, you can achieve the original god, enter the ranks of refining the gods, and knock on the door of the avenue for the first time. (Note: This book is based on the setting, there are reference books, but it deviates from the books, do not sit in the right seat!) ）

The first knock on the door of the avenue, without breaking the door, is still only a mortal, so the world knows the upper, middle and lower three dantians, but does not know the three hundred and sixty spiritual apertures, only by transcending the foundation and entering the forest of three cultivations, can the secret of the spiritual aperture be obtained.

But there is always a line in heaven and earth, the three major dantians in the upper, middle and lower are the three treasures of the world, and mortals through hard work to open the three treasures are equivalent to getting a key to open the door of the avenue.

The pieces of smoke and clouds-like essence were invested in the lower dantian, and Yan Lingyun was on the way to cultivation, which was equivalent to opening his first treasure.

He felt that the lower dantian was bulging, like a greedy giant mouth, and the whale swallowed the sea and swallowed the essence of the whole body, and then deposited in the dantian, undergoing subtle changes.

At this time, his extreme physical body is like a big furnace, refining a steady stream of essence and throwing it into the lower dantian, and then these essences are absorbed and transformed by the lower dantian without any indifference.

However, the cultivation of refining and transforming qi is only the beginning of qi training, and as more and more essence is absorbed in the dantian, a wonderful change has occurred.

If the essence of the smoke cloud is illusory, then the other "qi" that has been compressed and transformed by the dantian and then deposited is real, so this "qi" is also called true qi.

True Qi is intangible and qualitative, so it is domineering, and as the number reaches a high point, a huge tension is suddenly generated, as if it is about to explode the lower dantian.

Yan Lingyun kept in mind Bai Qianshan's advice, although he was not panicked, he relaxed himself as much as possible, to accommodate and guide.

The true qi accumulated more and more in the dantian, and the pressure generated became more and more great, gradually filling the dantian, and even oppressing the external essence Qi began to be unable to enter.

Yan Lingyun relaxed his body again and again, so that he entered a deep level of meditation, and then in the silence, he relaxed his body again, and suddenly, a feeling of penetration arose.

The true qi in the dantian also found an outlet at once, poured into a channel that seemed to come out of nothing, and gradually diverged, gradually spreading to the whole body, and suddenly, a densely interconnected "network" was sensed by Yan Lingyun.

These "network channels" distributed throughout the body are the meridians of the human body, which actually exist, but ordinary people cannot perceive them, and can only be accurately captured by practitioners through the operation of qi sense.

The meridians of the human body are distributed all over the human body, interconnected, and incomparably complex, and these complex connection points are called the acupoints by the world. People in the world can't perceive the meridians, but they can channel the meridians and release their potential through pressing and acupuncture, so as to achieve the purpose of curing diseases and prolonging life.

This metaphor is not only circulated in the secular world, but also in the spiritual world, and is regarded as the truth. It's just that people in the world don't know the secrets of the human body, and they worship the outer gods, while the cultivators worship their own bodies, so there are 360 spiritual senses.

There may be more than 360 acupoints in the human body, but after hundreds of millions of years of exploration, the cultivation world has finally recognized the 360 spiritual apertures corresponding to the number of Zhou Tian, and believes that it is the most able to nourish the gods and is a treasure of the cave.

The three major dantians of the upper, middle and lower human body, as the third of the three hundred and sixty spiritual apertures, contain the three treasures of human essence and spirit, and are the foundation of the world's life, so they are generally known to the world. When the monk builds the foundation, he excavates these three treasures, and then sublimates to the fullest and enters the forest of the Great Dao.

But the excavation of the foundation monks is different from that of the world!

People in the world do not know about spiritual practice, although they have the Three Jewels, they are completely squandering, they do not save a trace of provisions, they sit and eat empty, so they are born, old, sick and die, and their lives are short.

At the same time of digging, the monks will also cultivate the source, they use the essence of the flesh to raise the lower dantian, to raise the middle dantian, to raise the dantian with the god, between digging and raising, there is a virtuous circle, the potential is endless, and the longevity is long.

It's just that the monks build the foundation, and it's not so easy. The huge meridian network of the human body, born occluded, coupled with the existence of a spiritual aperture, is more like setting up an unbreakable level on a difficult and difficult road, at the beginning of the monk's qi practice, the following dantian is the furnace, the true qi follows the meridians and moves forward with difficulty, and when it encounters the spiritual aperture, it has to detour, so that the road ahead is more and more deviated, and finally although the whole body barely runs a circle, it is only a small Zhoutian, and there is still a large area that cannot be entered.

Only with the deepening of Qi cultivation and the accumulation of True Qi and the growth of True Qi over time, breaking into the Middle Dantian, can it run a larger area and carry it in a large Zhoutian.

However, Yan Lingyun's initial formation of true qi poured into the meridians, but he did not encounter any blockage, it was actually unimpeded, and when he encountered hidden spiritual apertures, he had to take a detour.

During this period, his true qi also encountered some free qi one after another, which seemed to be similar to the true qi, so he was assimilated after a pounce of his true qi.

Yan Lingyun was puzzled by this, but he didn't have the heart to think about it, he was calm about his body, he couldn't think about it, and let his true qi grow all the way, all the way forward, surging to the limbs and hundreds of remains.

Completely forgetful, the true qi carried a little Zhou Tian and returned to the lower dantian.

After a small week of transportation, the originally domineering true qi seemed to be much calmer, the pressure in the dantian was reduced, and the external coiled essence began to be invested again.

Yan Lingyun was not happy with things, not sad with himself, and started the second Xiao Zhou Tian again. Time passed quietly in such a cycle.
