After saying hello to Huo Jingshan, the two entered a state of retreat, and Liansheng specially sent a few disciples to guard outside their retreat room, not allowing anyone to disturb them.

Luo Changfeng has more than 60 years of strength, but because of the internal strength and mental method he has cultivated, the internal force in his body is vain, not condensed at all, and naturally, the power is not great.

Now he operates his internal force according to the mental formula of the Nine Yin True Sutra, and every week of operation, the internal force will be smaller by a circle, but the quality of his true qi is constantly improving.

By the time he found that the internal force had been compressed to the extreme, and he could no longer continue to compress it, there was only less than forty years of power left.

But the floating internal force has become an incomparably thick true qi, if the internal force is the white clouds floating in the sky, then the true qi is the dark clouds covering the top, as if it will condense into raindrops at any time.

Luo Changfeng knew that if the dark clouds really condensed into raindrops, then the true qi would no longer be true qi, but the true yuan, which had already surpassed the realm of the mundane, although the Nine Yin True Scripture was wonderful, it obviously couldn't help him get to that point.

In fact, this cultivation of martial arts and the development of the small universe in the body can be compared with several stages of the scientific and technological level.

When he began to cultivate internal strength, it was equivalent to the beginning of the industrial revolution in the small universe in his body.

Practicing internal force is equivalent to entering the era of mechanization.

The condensation of internal force into true qi is to enter the information age.

If the true qi is further condensed into the true element, it will be the space age, and human beings can already leave the earth.

And when the true element is compressed and condensed to the extreme, the martial arts golden pill is produced, and then the void is shattered, and the physical body is sanctified, and the physical body can cross the void with the physical body.

Then there is no doubt that this is already the interstellar era at this time.

This is the benefit from the future generations, even if Luo Changfeng is not in the realm, he already knows what the road will be like and how to go.

Unlike the natives of the reincarnation world, they have to explore little by little, crossing the river step by step by feeling the stones, taking detours without paying attention, and even stepping on the air, slipping off the stones, and being drowned in the water.

Even if he is a talented and intelligent hero, he will not be able to touch a higher level of martial arts realm due to the problem of the world limit.

In the world of the golden book, the innate realm of true qi is self-generated, self-operating, and endless, is already the limit, and the laws of the world are destined to the people of this world, unable to touch the realm of the true yuan that breaks through the mountains and the rivers with swords.

When Luo Changfeng was cultivating the Nine Yin True Scriptures, compressing his internal force to the extreme, and condensing it into true qi, his twelve canons and the eight veins of the Qi Sutra had all been opened.

Since then, Luo Changfeng has been born against the congenital, the true qi is self-generated, endless, even if he does not deliberately cultivate, the true qi is constantly running on its own, slowly growing, if you take the initiative to cultivate, the growth rate will naturally be faster.

It's just that this time, he and Dugu sought defeat in order to transform the internal force into the Nine Yin True Qi, which was completed in one breath with continuous exercises.

In normal times, you don't have to cultivate so diligently, because even if you cultivate so diligently, it's useless.

One of the peculiarities of the Nine Yin True Sutra is that cultivation pays attention to the hour, it is not useful if you practice diligently, it is not the corresponding hour of cultivation, and the growth rate of its power is extremely slow, and it is not much different from the growth rate of the normal true qi running on its own.

The formula has clouds: when the meridian is four positive, the Qi dantian palm is pushed forward, facing the north and the south facing the sky, meaning to follow the two palms in the middle, meaning to note the dantian a yang movement, and the left and right recycle the two acupoints.

From this mantra, it can be clearly seen that the time for cultivating the Nine Yin True Sutra is the four hours of the Child, Meridian, Mao, and Unitary, and after these four hours, the cultivation of other hours is basically ineffective.

These four hours are very particular, the sub-hour is the time when the cathode is born and the yang is born, and the sub-hour reaches the extreme in three quarters, and the noon is the time when the anode is born and the yin is born, and the noon reaches the extreme at three quarters.

The time is from the time of yin to yang, and the time of the unit is completed by the time of three quarters, and the time of unitary time is from the time of yang to yin, and the time of unitary time is completed by three moments of transformation.

In other words, to practice the Nine Yin Sutra, you only need to practice for three quarters of an hour when the four hours of Zi, Wu, Mao, and You arrive, and you only need to practice for one and a half hours every day.

This is also the reason why Lin Lingsu has practiced the Nine Yin True Scripture for twenty years, and while he has such profound skills, he can also practice light exercises such as spiral nine shadows, snake walking raccoon flips, and moving across the air to the fullest.

Cultivating the top exercises does save time, and the most important thing is that cultivating the Nine Yin True Sutra for an hour and a half a day, but the effect is stronger than that of ordinary exercises for a whole day, and the top exercises are so unreasonable.

Now that Luo Changfeng has practiced the general outline of the Nine Yin True Sutra, his strength has skyrocketed again, and his cultivation in internal strength has finally kept up with his external cultivation.

His innate true qi, whether in strength or quality, is no longer under the aura of heaven and earth, so to speak, the innate true qi itself is the aura of heaven and earth in the small universe in the human body, and it is the same and different source of power as the aura of heaven and earth in the great universe.

Since they are homogeneous, they can naturally cooperate well with each other.

Then some people will be surprised, since the innate true qi and the heaven and earth aura are homogeneous things, then why can the heaven and earth aura be attached to the body and condensed outside the body, and the true qi will disperse as soon as it leaves the body?

Very simply, the human body is equivalent to a small universe, and the human body is the container of this small universe, so the true qi in this container naturally operates reasonably, and will never dissipate.

But once the true qi leaves the body, it means that the heaven and earth aura of this small universe leaves this universe, and the small universe can no longer restrain these aura, and it will naturally disperse.

And the big universe outside the human body also has a container, but no one knows what that container is.

For people, the aura of heaven and earth in the great universe is the power outside the body, but for this great universe, these heaven and earth aura are the power in the body.

Every planet in this universe is an "internal organ" of this unknown container, and every living creature in the universe is the "internal force" of this unknown container.

Therefore, the heaven and earth aura of the great universe can be attached to the human body and not disperse, but the innate true qi of the small universe of the human body cannot do so, and it will disperse as soon as it leaves the body.

However, if the innate true qi is wrapped with the great cosmic aura and solidified it, then the innate true qi will not disperse, but solidify into a specific shape, which is the principle of the qi sword.

Luo Changfeng slowly finished his work, looked at the sky, it seemed to be noon, he remembered that he and Dugu were defeated after dinner, and when it was about to get dark, he entered a state of retreat, and he didn't know how many days had passed.

got up and opened the door, and the two Taoists guarding the door saw this and hurriedly greeted him, "Luo Shaoxia, you are out of the customs." ”

Luo Changfeng nodded and said, "How long have I been in retreat?"

One of the Taoists said: "The young man has been in retreat for two and a half days, and Senior Dugu has already left the customs in the morning and gone to the back mountain. ”

Luo Changfeng nodded, the quality of Dugu's internal force was higher than his, and it was understandable that he would go out of the customs first.

Now that they are practicing the Nine Yin True Scripture together, Dugu has surpassed him in terms of skill, and now if they compete again, the outcome will be unpredictable.

It depends on which of them can better use sword qi and qi sword, although Luo Changfeng's skill is inferior, but if his use is more subtle, it may not be without a chance of winning.

Moreover, his speed is always one line faster than Dugu's defeat, and when there is no sword qi, the effect of this line speed is not obvious.

But with the cooperation of sword qi, the speed is faster, and the advantage is greater.
