In front of me was a mysterious space about a hundred zhang square, and the whole space was extremely empty, only three clouds of different colors slowly drifted in the air.

These three clouds are pale cyan, pale red and pale white, but the clouds are not large, and even if these three clusters are connected together, they cannot occupy one ten-thousandth of this space.

At the edge of this mysterious space, three pillars the thickness of children's arms stand evenly.

These three pillars give the impression of supporting the space. It's just that these three pillars are a little thinner, and it feels like they might break at any time.

When you get closer to the pillars, you will find that they are made up of countless telanges, red, and white filaments. Each filament is thinner than a human hair.

And every once in a while, the three pillars will bend slightly, and at this time, countless tiny particles of cyan, red, and white will fly out of the pillars and throw themselves into the clouds in the air, and quickly merge with the clouds of the same color, and each light cloud will expand outward with a very small trace.

If you stay in this space for a long time, you will find that every time the pillars bend, the whole space will slowly shrink. And when the particles of three colors fly out of the column, it is the space that is the smallest. After that, the pillars will slowly stand upright, and the space will always expand a little first, and then slowly return to its original size.

This space is constantly compressing and expanding at an extremely slow pace, as if it is a beating heart.

......

At this time, Xiao An was sitting cross-legged on the futon, and a semi-circular light mask held Xiao An in it.

With a long inhalation sound, like a whale sucking water, all the aura in front of him was sucked into Xiao An's abdomen.

At this time, a magic weapon placed in front of Xiao An would always appear with a cloud of fine light, and some subtle spirit patterns would flicker on the surface of the fine light, and at the same time, countless milky white spirit patterns would also appear on the semi-circular light mask.

The spirit pattern on the fine light is exactly the same as the spirit pattern on the semi-circular cover, but it is much smaller, as if it is a miniature.

When the spirit pattern appeared, the surrounding aura rushed towards Xiao An's side like a moth to a flame. In the blink of an eye, it made up for the aura that Xiao An had just absorbed, and then the spirit pattern disappeared into the light mask.

When the spirit pattern on the light mask disappeared, the thin light on the magic weapon in front of Xiao An also disappeared, and a disc-shaped magic weapon appeared on the spot.

As Xiao An meditated, the spiritual patterns and thin light on the mask kept appearing and disappearing.

Soon Xiao An took a deep breath and slowly exhaled it, about to end this meditation.

At the same time, that mysterious space has also undergone a super-large compression and expansion.

When the expansion was over, the edge of the space had expanded a bit, and it had already crossed the pillar about a few fingers away. And the particles gushing out of the pillars were also several times more than usual, but these particles did not fly to the clouds in the air, but attached to the three pillars to form new filaments, making the pillars slightly thicker.

Xiao An, who was sitting cross-legged, finally ended his meditation, and the moment Xiao An opened his eyes, it seemed that a subtle lightning bolt passed through the room.

Xiao An didn't get up immediately, but quietly reminisced about something, and a surprised expression slowly crept up Xiao An's face, and after a while, he began to giggle with a big grin.

After three years of penance that did not see any effect, he finally entered the harvest period. First, he learned a very powerful "earth armor technique", and later he even got storage bags, outer disciple clothes, spirit stones and other items. Today, I finally succeeded in experiencing an "inner vision", and I was one step closer to the immortal in my mind.

Of course, Xiao An deliberately ignored the power of the earth armor technique, after all, this spell can only be used to strengthen the soil now, and it is a hard work to ram it in the secular world.

Xiao An began to sympathize with the boys who had been driven down the mountain, and these people were not all poorly qualified. It's just that some people can't bear this kind of unsuccessful penance, and in the third year of going up the mountain, they gradually give up their cultivation and collapse at the last moment before dawn.

The so-called "inner vision" is a function of cultivating the divine consciousness, and at this stage the divine consciousness is too weak to leave the body and can only move within itself. After possessing divine consciousness, you can clearly "see" the state of every muscle and tendon in your body, even the slightest blood vessel.

The advantage of having divine consciousness is that the slightest abnormality in the body can be clearly detected, and when practicing in the future, you can arrange the cultivation time according to your actual situation, so as to ensure that your cultivation is in a saturated state, and there will be no hidden injuries due to excessive practice.

After being promoted to the foundation building period, the divine consciousness will grow to the extent that it can be "out of the body", and at this time, it will be able to control flying swords and other magic weapons to fly into the air and carry out complex fighting methods.

"Inner vision" is not unique to immortal cultivators, and some martial artists in the secular world who have practiced qigong for decades can also achieve this state. It's just that the divine consciousness of a warrior cannot grow throughout his life to reach the realm of "divine consciousness out of the body".

And the strange space just now is the appearance of Xiao An "seeing" his dantian through his divine sense.

The three clouds of different colors in the dantian represent the three spiritual roots that Xiao An possesses, cyan is a wood attribute spiritual root, red is a fire attribute spiritual root, and white is a metal spiritual root.

This was Xiao An's first inward vision after opening his divine sense, and it happened to coincide with a small expansion of the dantian, which made Xiao An excited, and his impetuous heart couldn't calm down for a long time.

And those three pillars are the things formed by the exercises, they are the important pillars that support the dantian, and they are the key to whether the cultivation can step into the next stage. And the dantian is also known as the "sea of qi", so these pillars are also called "Dinghai" by the monks.

From the early stage of qi refining to the middle stage of qi refining, a large expansion of the dantian will occur. Before the expansion, the dantian will fluctuate violently, and the expansion will only begin when the fluctuation intensity is increased to a certain extent.

However, the human race's physical body is weak, and the vast majority of monks' dantian cannot withstand the damage caused by fluctuations, and when the damage endangers the safety of the dantian, the dantian will terminate this fluctuation, which means that the monk cannot enter the middle stage of qi refining.

The sages of the human race pioneered the method of forming pillars in the dantian, and successfully integrated this method into the exercises. With the support of the pillar, the strength of the dantian has been increased a lot, which greatly increases the success rate of the expansion of the human dantian.

But there are always two sides to things, although this practice increases the strength of the dantian, it slows down the cultivation speed, and the monk needs to pay longer to increase the strength of the dantian during the qi refining period. The lifespan of the human race is slightly shorter, and the slightest relaxation will lead to a decline in physical condition, so the monk must enter the next realm before his own qi and blood fail, otherwise he can only wait for his longevity to run out and die. And after entering the next realm, the monk's lifespan will increase a lot, which is enough to support the impact of the next realm.

Xiao An pinched the trick with both hands, and a white light fell on the magic weapon in front of him, and with a soft sound of "horn", the cover outside Xiao An's body disappeared like a bubble bursting. The rich aura quickly dispersed in all directions, and in the blink of an eye, the surrounding aura returned to the level before the magic weapon was activated.

After careful experience, Xiao An found that the Spirit Gathering Array Disk had increased the concentration of spiritual energy by about two percent, and he heard that other people's magic weapons could only be increased by one to one and a half percent, and his own magic weapons were much better than others.

Then Xiao An took the magic weapon in his hand and glanced at the spirit stones inlaid behind the magic weapon, the color of the three spirit stones was much darker, and it was estimated that they could still be used for seven or eight days.

It has been a month since I participated in the Zongmenfang City to purchase magic weapons, and other people's Spirit Gathering Array Disks need to replace spirit stones at most a month.

Xiao An took the Spirit Gathering Array Disk in his hand and looked at it with satisfaction, and finally saw the appearance of this magic weapon clearly at this time, it was the one that Zhao Liang wanted to buy at a high price.
