The unity of spirit and flesh is an advanced method of refining the body. ** and soul are two completely different powers, but cultivating the unity of the spirit 'flesh' can merge these two forces into one, so that the power is pure and bursts out with more powerful power.

The power of the 'flesh' body is transformed into soul power, and the soul power is transformed into the power of the 'flesh' body, and you can switch between the two at will, which is the great realm of the unity of the spirit and 'flesh'.

If you cultivate to this realm, you will have a great advantage in battle, and it can even be said that those who are united with the 'flesh' of the Great Spiritual Spirit under the same cultivation are invincible existences.

Such a person can concentrate the power in his body and burst out with a power that is several times that of cultivation.

For human beings, it is more difficult to achieve the unity of spirit and flesh than to ascend to heaven. First of all, the structure of the human body does not allow the unity of human spirit and 'flesh'; secondly, human beings major in martial arts, resulting in soul power being far weaker than the strength of the 'flesh' body, and the soul power cannot assimilate the 'flesh' body at all.

But for high-level demons, it's easy to catch.

The cultivation methods of different races are very different, although the human race does not have the same obvious effect as other races before the emperor level, but after reaching the emperor level, the copper skin and iron bones are enough to open the world.

According to what the demon said, if Lin Xiao wants to cultivate the unity of spirit and 'flesh', he must use the skin as the peak and temper the skin with soul power.

The skin is used instead of the qi to connect the whole body, so that the soul power is spread around the body.

This method has not been tried before, the qi is empty, but the skin and flesh are real. In order for soul power to exist in the skin, it is necessary to find the part where the soul is stored.

This point is difficult to find in general**, but it is not difficult in a generation of demons.

A generation of demon bodies is born from heaven and earth, and its skin structure comes from the purest demon source in heaven and earth.

The demon source is equivalent to the aura of heaven and earth, the aura of heaven and earth comes from the righteous path of the world, and the source of the devil comes from the demon path of the world.

The most important thing is that the Demon Source can store souls, so the Demon Body constructed by the Demon Source will also have the same function.

Although Lin Xiao's ** is not a pure demon body, it is a combination of a demon body and a human body. But since there is a demon body, it means that there must be an organization in its body that is composed of a demon source, and it is sure that a place to store the soul can be found.

At this point, the demon thinks that the greatest possibility is on the surface of the skin, and the demon also made this judgment based on the changes in Lin Xiao's body.

Wearing black skin was the most obvious change that appeared on Lin Xiao's body after the demon devoured the demon cocoon and the demon barrier.

Lin Xiao sank into cultivation, and the magic of the unity of spirit and flesh slowly rose in Lin Xiao's body. Gradually, Lin Xiao's 'flesh' body has undergone tremendous changes.

Lin Xiao's ** is gradually disappearing, first the hands, then the feet, then the arms, and then the legs......

Later, Lin Xiao's entire body turned into a cloud of mist except for his head.

The clouds and mist were misty, Lin Xiao's head was surrounded by a thick mist, the only difference between him and the people in the demon clan was that the demon qi was black, but the fog around Lin Xiao exuded colorful light.

Red, orange, yellow, green, blue, purple are mixed together, and its shape is gorgeous, like a rainbow after rain. In the rainbow, Lin Xiao's head loomed, and it seemed to be covered with sunshine, with an indescribable holiness.

Lin Xiao, who was in the midst of cultivation, didn't know the situation of the outside world, and the biggest feeling that the unity of cultivation spirit and 'flesh' gave him was that his body was gradually getting lighter, as if he would be blown down by a gust of wind at any time.

Until this moment, Lin Xiao found that the head was getting heavier and heavier, and the head that was not heavy now felt like a mountain pressing on his body, making Lin Xiao unable to kick out.

Holding on with difficulty, Lin Xiao knew that it was the most critical time.

The first layer of the unity of spirit and flesh is the incarnation of the spirit by the flesh, and the biggest bottleneck in this layer is to turn the head into soul power.

The skull is the toughest part of the human body, and secondly, there are many dead 'holes' on the skull, so Lin Xiao does not dare to act rashly.

......

It only took Lin Xiao two hours to turn the parts of his body into souls except for the skull, but Lin Xiaosheng was stuck in the skull for three hours without any progress.

The head was like a hedgehog, so that Lin Xiao couldn't find a starting point.

"Hedgehog?"

Lin Xiao suddenly frowned slightly, as if he had thought of something, but he couldn't catch it for a while.

It wasn't until a quarter of an hour later that Lin Xiao's frowning brows slowly relaxed, and a faint smile flowed from the corner of Lin Xiao's mouth.

If you are familiar with Lin Xiao, you will know the meaning behind this smile, it means that the problem is solved.

The hedgehog is indeed difficult to start, but if all its thorns are pulled out, the hedgehog can only be slaughtered.

From this, Lin Xiao was inspired that the safest and easiest part of the head to break through is the hair, and if the hair is solved first, a breakthrough may be found from it.

Controlling the soul out of the body, Lin Xiao's head suddenly appeared with spiritual power, and a faint spiritual power lingered tightly in his hair. After a while, Lin Xiao's hair melted into the clouds, and Lin Xiao turned into a bald monk.

Cross-legged, calm, at first glance, I really want to be a monk who has attained the Tao.

As the hair was soulified, Lin Xiao decided to start with the hair holes. The thoughts in the brain are like strands of hair entering the hair holes, occupying the position that originally belonged to the hair.

These divine thoughts began to work after drilling into the hair holes, refining the surrounding scalp and skull little by little under Lin Xiao's control.

Gradually, Lin Xiao's entire head began to melt from top to bottom, blending into the clouds, leaving only a pair of eyes blinking in the clouds.

......

It was done, and Lin Xiao's entire body finally turned into a soul after six hours.

Today's Lin Xiao is a cloud of mist, suspended above the passage. The demonic energy accumulated in the passage was also released at this moment, and it passed through the clouds and mist like a bank.

A quarter of an hour later, the demonic energy in the passage finally returned to normal, and the originally blocked passage became unimpeded at this moment.

Seizing the opportunity, Lin Xiao passed through the passage in one fell swoop, and came to the outside of the passage in the blink of an eye.

Looking back at the passage behind him, Lin Xiao still had palpitations. If it weren't for the fact that he happened to get the demon barrier quenching body in the volcanic stone 'hole', Lin Xiao was afraid that he would have to be forced to give up this **.

In this way, the ** absorption of the magic cocoon and the demon barrier that the demon occupied him strongly in the stone 'hole' helped him a lot.

Since falling into the cliff, Lin Xiao has been in danger several times in more than a dozen hours and almost died.

But at the same time, Lin Xiao also got great benefits, the improvement of soul power, and the refining of **, all of which saved Lin Xiao months or even years of cultivation.

No matter what, Lin Xiao came out alive.

This place is still in the demon cave, how many dangers are waiting for Lin Xiao in front of him, it is still unknown now, if you want to get out of the demon cave, Lin Xiao is afraid that she will have to go through countless such life and death tests.

But at this moment, Lin Xiao's heart is much calmer, a little less impatient in the 'cave' of the volcanic mountain, and a little more mature and steady.

With these successful experiences, Lin Xiao believes that nothing can defeat him.

After sorting out his mood, Lin Xiao looked back. Suddenly, Lin Xiao's eyes let go in vain, and his mouth grew into a circle, and he was speechless.

Through these open eyes, it can be seen that Lin Xiao was very shocked at this moment, as if he had seen something unbelievable.
