Only when the mind is free of distracting thoughts, the essence produced by the body can be called innate essence. Ordinary people can only rely on a good sleep to ensure that their minds are free of distractions, so as to obtain innate essence to nourish the body.

However, if a health practitioner wants to build a successful foundation, he or she must accumulate a very abundant innate essence, so even when he is awake during the day, he must keep his mind free of distractions.

Ma Chuan has already practiced the health recipe to the ninth level, usually pure heart and few desires, meditating for an hour before and after each day in the afternoon, and the accumulated innate essence is already a lot, and it has passed through the tail and the spine.

Now the main purpose of the retreat is to accumulate more innate essence, open up the jade pillow acupoint, and build the foundation is considered a success, and the back of the magpie bridge is just a matter of course.

But to open up the jade pillow acupoint, the innate essence required is huge. Fortunately, Ma Chuan is young and his body is in a vigorous period, and he does not need to use the pill of lean qi, as long as he keeps his mind free of distractions, after a period of time, he can accumulate enough innate essence.

It is not easy to keep your mind free of distractions for a period of time, in addition to retreat and meditate, you also have to clear the valley.

However, the Bigu Technique is a basic spell that can only be practiced by cultivators above the Foundation Realm. Ma Chuan, who is a health practitioner, wants to Bigu, so he can only take Bigu Dan, although it is worse than the real Bigu technique, but it is also stronger than fasting.

Speaking of fasting, Ma Chuan has not eaten meat for several years, except for a barbecue with Jin Can and others. It's not because he's old-fashioned and has to keep the precepts, but because he has to. Advanced health practitioners, who are already very healthy, do not need meat to supplement nutrients. Especially after practicing the health exercises to the sevenfold level, it is necessary to focus on cultivating the mind, and at this time, the smell of meat will affect the state of mind.

Ma Chuan has been in Qingxi Valley for so long, and of course he understands why. People and animals have three souls and seven spirits, and after death, the three souls leave, but most of the seven spirits remain in the body. High-level health practitioners, who focus on cultivating the mind, will naturally be affected by eating animal meat.

In Ma Chuan's view, the Seven Spirits are the armies of the seven vassal states in his heart, and when the three commanders leave, there are huge routs left, and no matter what army touches these huge routs, they will be affected.

That's why if you want to be pure, you have to fast. And now if Ma Chuan wants to build a foundation, he must be free from distractions, because all things have a will, including plants, but there is a difference between more and less, ignorance and wisdom.

After refining, the Bigu Pill contains very little will, and it is barely enough to use it for Bigu.

After no longer doubting the method of building the foundation, Ma Chuan commanded the troops of an army in the idol on the first day of the first month to absorb the power of the will, and then prepared to build the foundation.

When it came to building the foundation, Ma Chuan was secretly glad that because he was sitting cross-legged and practiced the primary sheng divine technique, he unconsciously used the innate essence of his body to feed the army in his heart, so he failed to practice internal strength. Otherwise, we must first abolish our internal strength before we can successfully build a foundation.

In fact, the purpose of practicing internal skills is also to open up the two veins of benevolence and supervision, which is called Yitong. That is, with impure thoughts, guide the impure innate essence, start the lower dantian, pass through the lower magpie bridge, rush to Changqiang, pass the life gate, break the jade pillow, enter the benevolent vein through the upper magpie bridge, and finally return to the lower dantian.

When the transparent force on the spiritual platform reaches more than one brigade, the internal force in the lower dantian is transformed into innate qi, that is, the innate master.

Whether it is Yitong or Qitong Rendu Ermai, the ultimate goal is to make the body change from acquired to congenital, and acquired breath to fetal breath, and there will be a leap forward in all aspects. However, there is a very big difference between the Qitong Ren Du Pulse and the Yi Tong Ren Du Second Pulse, that is, once the former is successful, the lifespan can reach three Jiazi, while the latter can break through the limit of two Jiazi, but it is not as good as the former.

After Ma Chuan began to retreat, he did not leave the side hall and sat quietly, and the entire square inch mountain was moved to the three inches of the lower dantian.

After the retreat to the fifth day, Ma Chuan felt that the soldiers of the country of desire and Xiguo were in chaos, and the troops of the two brigades of the country of desire, plus the strength of one brigade of the country, 1,500 troops, rushed directly to the three inches of the dantian.

Although the four hundred and ninety-nine transparent troops and one soldier of the Desire Country on the Lingtai occupied a favorable position and held three inches from the lower dantian. However, there was a huge disparity in the strength of the two sides, one brigade against three brigades.

This is the most critical and the most difficult moment to be proud of, after all, Ma Chuan has not long passed the year of the weak crown, and his body is in a period of vitality, and the essence in the lower dantian has reached a very full state at this time, which will of course cause a large number of mutinies in the army of desire and happiness.

As soon as the two sides fought, Ma Chuan felt that in the lower dantian, the warm current was moving more frequently than before, the whole body was like a spring breeze, and the hearty feeling was spontaneous, and the pores were naturally dilated, like soaring clouds and fog. It is like a couple who have fallen in love, you and me, like glue and paint, soft as jade, and the heart is ape, and all kinds of feelings come one after another, which is indescribable.

Ma Chuan sat on the futon in the side hall, his eyes seemed to be closed, his hands pinched the meridian buckle, and his face was quite calm, but in the lower dantian, it was a tragic offensive and defensive battle.

Generally, to build the foundation and pass the second vein, it is necessary to let the transparent troops on the spiritual platform reach more than one brigade, that is, to reach the state of mind of the sergeant, so that they can be sure to resist the mutinous national forces when building the foundation.

But breaking through from the corporal's state of mind to the sergeant's state of mind can be met but not sought, which requires a great creation and a mysterious epiphany to achieve. How many health practitioners and martial arts masters who have opened up the second vein of Ren Du have spent decades not getting such an epiphany.

Even if Ma Chuan used the sufficient wish power of the Wuhou Temple, he saved decades of gradual enlightenment, and his state of mind reached the peak state of the corporal, that is, there were 499 transparent soldiers on the spiritual platform. But if he wants to break through to the sergeant's state of mind, he doesn't know when he will encounter the epiphany of mysteries.

Fortunately, among the methods of building a foundation, there is a way to use the fierce battle in the heart to break through the state of mind in the battle when building the foundation, which can also be regarded as a shortcut. Since it is a shortcut, the natural conditions are harsh, and the risk is greatly increased, and the chance of suffering from the demon is infinitely increased.

To build a foundation in this way, you must reach the peak state of the corporal, and you almost can't do it at all. It is also necessary to be four or eight years old, and the body is in a vigorous period, and both are indispensable.

Ma Chuan has met these two conditions, so now a tragic battle is taking place three inches down the dantian. The strength of the desire and the country is like a tide, going forward and one after another, constantly attacking the key points, and the transparent troops close to a brigade are holding on to it.
