In the sea of aura, Chu Jingtian sat cross-legged, constantly running the "Chaos Derivation Technique".

However, at this time, he was absorbing the complete heaven and earth aura.

When refining his body, in order to have a better refining effect on his body, he had always only absorbed the fire attribute elements in the aura, but now, his refining body has all ended, and there is no need to do so.

The liquid heaven and earth aura, after being absorbed into the body, was transformed into a gaseous state again, but it was more refined than the ordinary gaseous aura.

Because of the liquid aura, it is the gas aura that will only appear when it reaches a certain concentration.

However, the aura of heaven and earth that he had absorbed into his body now did not belong to Chu Jingtian, and if he stopped running the exercises, these aura would gradually dissipate.

In order for these spiritual qi to be preserved, Chu Jingtian had to run the exercises and transform them into his own true qi.

However, the true qi must be stored in the dantian, otherwise the amount of true qi that can be contained is very limited only by relying on the meridians in the body.

Therefore, before transforming the aura of heaven and earth into true qi, Chu Jingtian must also do one more thing - open up the dantian.

Dantian, also known as the sea of qi, is located in the third third of the umbilicus of the human body, which is a place specially used by martial artists to store true qi, but the so-called dantian qi sea is actually not an organ of the human body, but a space opened up by martial artists in the body.

The size of the dantian not only determines the amount of true qi that can be stored in the martial artist's body, but also affects the strength of the martial artist.

Even, it will also affect the strength of the martial artist when he enters the Danwu Realm in the future, as well as the subsequent growth potential.

Therefore, the step of opening up the dantian is a crucial step for martial artists.

Chu Jingtian continued to absorb the aura, and the amount of aura absorbed at this time would be directly related to the size of the opening up of the dantian, so he had to make every effort to let his body contain more aura.

As more and more aura entered his body, his body already had a faint feeling of swelling. However, he showed no signs of stopping, but continued to operate the exercises, constantly absorbing them.

At this time, the importance of perfect body refining is reflected.

As I said before, the human body is like a container, and a martial artist who cannot perfect his body has "trachoma" on his body.

When they open up the dantian, when the aura in the body reaches a certain amount, due to the pressure, the aura in the body will leak out through the "trachoma". At this time, they will no longer be able to absorb more aura, because the more they absorb, the more they will leak out.

And Chu Jingtian is different, he is a perfect refining body, and he doesn't have any "trachoma" on his body, so as long as his body hasn't exploded, he can always absorb and contain aura.

This is like two balloons, one blows to a certain extent and leaks, but the other can continue to blow, the gap between this is self-evident.

Absorb......

Absorb hard......

At this time, Chu was shocking, and there was only this one thought in his mind.

Faintly, he began to feel some pain in his viscera, which was the result of being oppressed by a large amount of spiritual energy.

By this time, ordinary martial artists had already begun to "leak air", but Chu Jingtian just endured the pain and continued to absorb it......

Perfect refining of the viscera makes his viscera extremely strong, and this pain will not have any bad effect on him.

Time passes slowly.

Chu Jingtian's body was obviously swollen, as if he had eaten fat in an instant, which was supported by a large amount of spiritual energy in his body.

At this point, he really turned into a 'balloon'.

However, Rao still showed no signs of stopping, and was still desperately absorbing the aura.

At this time, he had to thank the "Chaos Derivation Technique", the strong defense brought by the exercise made his body extremely tough, so it hadn't exploded until now.

However, Chu Jingtian was still absorbing.

The huge amount of spiritual energy, the oppression brought by it is terrifying, if it weren't for the fact that his viscera and flesh are strong enough, I am afraid that he would have bleeding internally.

Even, the huge oppressive force has made his brain extremely congested, and the whole person is a little dazed.

However, in his mind, there was still that one thought - absorb the aura, continue to absorb the aura......

In a daze, Chu Jingtian didn't know how long it had been.

At one point, he suddenly heard a "buzz...... Buzz ......".

The sound was so soft that it felt like a stream of water hitting the drum surface, causing the drum surface to tremble slightly.

In an instant, Chu Jingtian's mind came to his senses.

Did he understand what the sound was?

Because of the huge amount of spiritual energy, his body became swollen, and his skin was already tightened.

Now, his skin was like a taut drum surface, and the sound was the liquid aura around his body washing over his skin.

At this time, he felt that there was a tearing sensation coming from the skin, but due to the perfect skin training, the skin became tough and not cracked.

Shocked in his heart, Chu Jingtian immediately stopped absorbing the aura.

He had no doubt that even if he absorbed a little more aura, his body would really explode.

Taking a deep breath, Chu Jingtian controlled the pores of his whole body to be closed to prevent the aura from leaking out, and then gently closed his eyes.

Next, it is the most critical step - to open up the dantian.

After a while, Chu Jingtian opened his eyes, and then began to try to control the spiritual qi near the dantian.

But after trying, he couldn't help but smile bitterly.

Because, the amount of aura in his body is so much that the aura can't move at all.

"What should I do? Do you want to let go of some aura?" Chu Jingtian was very helpless, he only wanted to absorb as much aura as possible, but he didn't expect that he would not be able to move this stubble if he had too much aura.

However, there will be such a problem, and he will probably experience it for the first time in many years.

"No, you must not let go of the aura, now the pressure of the aura is so great, once you start to release it, you can't stop it at all, and this half a day's work will be in vain. ”

Chu Jingtian's thoughts were spinning in his heart.

"Master, use your spiritual power!" The voice like a dream came into Chu Jingtian's ears at this time.

She had been observing Chu Jingtian's actions, so when Chu Jingtian failed to control the aura, she found the abnormality, and after thinking about it, she also understood the truth, so she reminded her.

"That's right!" Chu Jingtian's eyes lit up, and he immediately controlled a spiritual power of his own, and probed towards the dantian position along his body.

Although a large amount of spiritual energy was now gathered in his body, the spiritual power was formless and substantial, so it was easy to pass through the spiritual energy and come to the location of the dantian.

Then Chu Jingtian turned his spiritual power into a cyclone and began to rotate gently at three points below the umbilicus.

This action was originally to be completed with aura, but Chu Jingtian had no choice but to use spiritual power.

The cyclone was turning gently, and Chu Jingtian seemed to be able to feel that the invisible 'membrane' at his dantian was thinning and permeating.

And when that 'membrane' is penetrated, it is when his dantian is opened.

More than ten minutes later.

"Smack!"

There seemed to be a slight cracking sound in Chu Jingtian's body, and immediately after, he felt that the huge amount of spiritual energy in his body seemed to have found an outlet for catharsis, and frantically poured into that exit.

Chu Jingtian felt that a void space suddenly appeared in his body, and that space was in his body, closely connected to his body.

Moreover, with the influx of a huge amount of spiritual energy, the space is constantly getting bigger and bigger......

The pouring of spiritual energy made De Chu's shocking body slowly return to its original state like a deflated ball, and it was only then that he had time to remove the spinning spiritual power cyclone at the dantian.

It's just that the moment he saw the cyclone, Chu Jingtian's heart moved violently, and the ghost made the god worse, and he remembered the spiral body technique.

At this moment, he suddenly had a bold idea in his heart.

Immediately, he controlled all his spiritual power and rushed towards the dantian.

After all the spiritual power entered the dantian, Chu Jingtian immediately controlled the spiritual power to turn into a dragon scroll and spin in the dantian.

And with the rotation of the spiritual power tornado, the aura that poured into the dantian was also driven to rotate.

"It's done!"

There was a secret scream in his heart, and Chu Jingtian's eyes couldn't help but show a hint of excitement.

This is the inspiration he got from the spiral body technique, the spiral body technique is very powerful because of the spiral air flow, if he makes his true qi spiral, then the power of the true qi will also increase?

He wasn't sure, but he did it decisively, and even if it didn't work out, there was nothing to lose.

A huge amount of aura is still pouring into the dantian, and Chu Jingtian has absorbed too much aura, even if the aura is like a torrent of catharsis, it will not end for a while.

is also not over, and his dantian is still getting bigger......

An hour later.

In Chu Jingtian's body, there was finally no trace of spiritual energy, and all the spiritual energy poured into the dantian.

At this time, in his dantian, there was a spinning tornado.

Taking a nervous breath, Chu Jingtian carefully dispersed the spinning spiritual power in the center of the tornado.

However, the mental power was withdrawn, but the tornado was not affected at all, it was still spinning rapidly, and the structure was extremely stable.

At this moment, Chu Jingtian finally couldn't help laughing, laughing maniacally.

This means that the true qi he cultivates in the future will all have spiral characteristics, how can he not be happy?
