Guo Yi knew that the size of the dantian was even more important than his cultivation, and with his cultivation talent, even if he didn't make any progress here in the Ice and Fire Tomb.

Guo Yi believed that after going out, his cultivation speed would surpass that of most geniuses.

However, the dantian is different, Guo Yi has not found the existence of dantian in other cultivators until now.

Guo Yi believes that as long as the role of the dantian is well developed, it will definitely be the greatest guarantee for him to become a top powerhouse in the future.

And after this afternoon's dream of testing and analyzing his body, he also gave some ways to expand the dantian.

Guo Yi is the kind of character who does what he thinks, and after asking about some details of the dream, he took out hundreds of fire crystals.

Guo Yi put these fire crystals all over his body, and even sat under his buttocks, there were more than a dozen.

When expanding the dantian, it would never be enough to hold a few fire crystals in his hand, so Guo Yi adopted this method.

For others, it may be necessary to use physical contact to absorb the mana inside, but Guo Yi is different.

The mana vortex in Guo Yi's dantian has a special suction force for any mana, and Guo Yi believes that with the characteristic of the mana vortex, he can directly absorb the energy in the fire crystals around him.

"Dream, let's get started! You deduce! Guo Yi took a deep breath and slowly entered a state of concentration.

When killing this afternoon, Dream completely recorded Guo Yi's physical state, and now Guo Yi wants to re-simulate that state, so that the dantian can continue to expand.

According to the dream deduction, Guo Yi began to slowly run the Supreme Exercises. Let the mana vortex continue to accelerate.

Normally, in the case of cultivation, the speed of the mana vortex would be a full double that of usual.

But that's not what Guo Yi needs. Because when he was fighting today, the mana vortex was constantly stimulated by Guo Yi. The speed is a full five times faster than usual, so that the mana vortex can be increased.

"Not fast enough, still not fast enough!" Fine beads of sweat were already oozing from Guo Yi's forehead.

Guo Yi is now urging with all his might, but the speed at which the mana vortex is running can only be maintained at three times the speed at most.

In fact, this is also very normal, because when fighting, Guo Yi's mana is constantly consumed, so that there is no obstacle when refining mana, and the speed of the mana vortex is of course fast.

And now it's time to cultivate. The mana in Guo Yi's body is full, and of course there will be a lot of resistance to operation.

In fact, this principle is like inflating a tire, when the tire is out of air, of course, it is easy to inflat, but when the tire is full, it is very difficult to inflat.

And now Guo Yi is like this, under the rapid rotation of the mana vortex, Guo Yi can even feel that his cultivation is constantly soaring, but the mana vortex has not grown in the slightest.

"It's really only time to fight again. In order to increase the mana vortex? After Guo Yi tried for half an hour, he began to doubt whether his approach was correct.

"No matter, improve your cultivation first, and continue to expand your dantian tomorrow." Guo Yi is also an open-minded person. After rejecting this method, he decided to improve his strength first.

"Guo Yi, why don't you give it a try. When running the Supreme Exercise, at the same time, use the way of flame to urge the mana vortex. "Just when Guo Yi was ready to give up trying. Suddenly, a dreamy voice came.

Hearing the dreamy sound, Guo Yi's body shook violently. If he didn't talk about it, he wouldn't have thought of it at all.

The mana in the mana vortex is not ordinary mana, and the mana inside is the supreme mana that contains the path of flames.

In other words, in addition to using ordinary methods to urge him, Guo Yi can also use him as the way of flame to urge.

Thinking of this, Guo Yi immediately took action, and under the urging of Guo Yi's spiritual power, the mana vortex, which could only maintain a maximum speed of three times, actually began to accelerate again.

Triple speed, quadruple speed, five times speed, six times speed.

When the speed reaches six times the speed, the speed of the mana vortex does not increase.

And Guo Yi also discovered that when the speed reached five times, the mana vortex began to slowly increase.

And when the speed reached six times, the mana vortex could almost increase at a speed visible to the naked eye, and the dantian was also constantly expanding.

Feeling this scene, Guo Yi immediately became excited, he knew that today's discovery was equivalent to opening another door to the strong.

Guo Yi believed that in the future, his dantian would even grow into something that those ninth-order martial saints would be envious of.

After confirming that this method was feasible, Guo Yi began to concentrate on cultivation, so that not only was the dantian constantly expanding, but Guo Yi's cultivation was also soaring at an extremely terrifying speed.

Guo Yi has only been cultivating for an hour, and he has already touched the bottleneck of the late stage of martial arts, but Guo Yi is not in a hurry to impact this bottleneck at all, but suppresses his own cultivation as much as possible, so as to make his foundation more solid.

However, with the help of the fire crystal, Guo Yi's cultivation speed was too terrifying, and after another hour, Guo Yi felt that he could no longer suppress the realm.

Rumble!

When Guo Yi let go of the suppression of cultivation, he suddenly felt a shock in his body, and he didn't need Guo Yi's deliberate impact at all, the majestic supreme mana in his body had already broken by itself, the bottleneck of the later stage of the martial artist.

After breaking this bottleneck, Guo Yi suddenly felt a burst of comfort, as if his body was soaked in a hot spring, and that comfortable feeling almost made Guo Yi addicted to it.

The remnants of Guo Yi's sanity still made Guo Yi not forget to urge the mana vortex with all his might.

Because at the moment when Guo Yi broke through the bottleneck, his body seemed to open another shackle, and all parts of his body were nourished by mana, and even the meridians in his body were constantly widening under the nourishment of mana.

The meridians that were originally full of mana suddenly became thinner after being promoted. And at this time, when the mana vortex in Guo Yi's dantian rotated, there was no obstacle in the end.

Under Guo Yi's full urging, the speed of the mana vortex was still soaring.

Six times faster, ten times faster, fifteen times faster, twenty times faster.

After the speed of the mana vortex increased to a full twenty times, it did not increase. And at this time, the speed at which the mana vortex became larger, compared to before, was not on the same level at all.

Before, the mana vortex was growing, and it was as slow as a snail, but now its increasing speed was like blowing up a balloon, expanding at a terrifying speed.

The time for Guo Yi's promotion lasted for half an hour, and after half an hour, the dantian, which was originally only the size of a teapot, had become the size of a bucket at this time.

And now the mana that Guo Yi's dantian can store is probably comparable to a powerhouse in the early stage of the Martial Sect. (To be continued.) )
