When he was in Jiangbei City, although Ning Yan had not used the best spirit stone to cultivate, it was not that he had never heard of it.

On the Kuixing Continent, there are a large number of spirit stone veins. The spirit stones used by warriors in their cultivation are basically derived from these spirit stone veins buried in the underground of mountains and rivers.

And in these spirit stone veins, special spirit stones associated with ordinary spirit stones are sometimes found. This special spirit stone is also the best spirit stone.

Compared with ordinary spirit stones, the number of top-grade spirit stones is extremely rare. Even, in some small veins, not even a single top-grade spirit stone could be found.

Because of this, in the various cities of Lingnan County, it is very difficult to buy the best spirit stones directly with gold coins in places like commercial buildings. None of the commercial buildings like Jiutufang in Jiangbei City are directly sold with the best spirit stones.

Therefore, its value is not convenient to measure directly in gold coins.

In the auctions of various cities, there are often traces of the best spirit stones. Under normal circumstances, the final transaction price of a top-grade spirit stone can reach more than 10,000 gold coins.

In other words, the ten top-grade spirit stones that Dean Wu Xue had just awarded to Ning Yan were worth at least 100,000 gold coins.

That Pang Qiyuan should have also been rewarded with ten top-grade spirit stones.

Of course, the reason why the value of the best spirit stones is so high is not that the number is scarce. Rather, the spiritual energy it contains is not known to be many times more pure than ordinary spirit stones.

After making sure that what he was holding in his hand was the best spirit stone, Ning Yan's mood also became excited.

As soon as his mind moved, he dodged, jumped onto the bed, and sat down cross-legged.

He couldn't wait to immediately use the best spirit stone to impact the innate realm.

The eyes are gently closed, and the Mixed Yuan One Qigong Mind Method works.

In the martial arts meridians, the vitality slowly flowed.

Of the ten top-grade spirit stones, Ning Yan held one of them in his hand, and the other nine were placed beside his body.

When he felt that his state was almost adjusted, the operation of the Mixed Yuan One Qigong suddenly accelerated.

At this moment, on the surface of Ning Yan's body, a layer of vitality barrier visible to the naked eye appeared.

The aura contained in the top-grade spirit stone in his hand frantically poured into his body. This aura looked like a silver rope the thickness of an arm.

"Boom!"

The surging aura poured in, causing De Ning's body to shake slightly.

His cheeks flushed instantly!

That feeling was as if a burning flame had penetrated into his martial arts meridians.

The burning heat and severe pain swept through the body in an instant.

Even the Golden Wheel Star Soul in the Sea of Knowledge trembled slightly. If it weren't for the Star Soul being strong enough, I'm afraid it would have been dispersed by this energy.

At this moment, Ning Yan almost forgot to run the Mixed Yuan One Qigong Mental Method.

The aura contained in the best spirit stone is too domineering and ferocious. And the speed at which Ning Yan absorbed the aura of the best spirit stone was too fast.

There was too much aura pouring into the body at once, which was enough to burst the meridians of most of the Nine Heaven Realm martial artists.

Fortunately, Ning Yan's meridians are wide and tough enough.

Little by little, time passed.

Under the operation of the powerful Mixed Yuan One Qigong Method, the pure aura in the meridians is quickly transformed into vitality.

Ning Yan was engrossed in his attention, not daring to be distracted in the slightest.

With the ability of the mental method, he manipulated the vitality in the meridians as if it was about to overflow, and slammed the level of the second pulse of Ren Du.

As long as the Rendu Second Vein level can be broken away, the martial arts meridians of the whole body can form a complete closed loop. The vitality in the body will run freely and smoothly in all the martial arts meridians.

With each impact, a piercing pain is formed. However, Ning Yan didn't care at all.

He didn't seem to feel any pain at all.

It's just that the cyan robe on his body has been completely soaked with sweat.

Two hours later, the energy of the first top-grade spirit stone was exhausted. The level of Ren Du's second pulse seems to have become a little weaker.

Without any hesitation, Ning Yan directly picked up the second top-grade spirit stone and continued to absorb and transform.

And so on.

Finally, more than twelve hours had passed, that is, a day and a night. The second pulse level in his body was finally broken through.

The rolling vitality in the meridians is as if it has found an outlet, and it rushes through the level that has been opened with ferocity.

At the same time, Ning Yan also felt that the power in his body was increasing at an astonishing speed.

And that's not all.

His perception ability has also been greatly improved. The aura that exists between heaven and earth has gradually been perceived.

As his mind turned, the aura that existed in the space around his body slowly seeped into his body without his deliberate control.

The blood on Ning Yan's face gradually receded, and his breath slowly returned to stability.

The vitality in the meridians regained its calm after the initial frantic rush.

He whispered, "This...... Is it the Innate Realm? Even if you don't deliberately cultivate, your body can take the initiative to absorb the aura of heaven and earth and transform it into vitality! ”

In his eyes, a flash of light burst out.

He stood up, his right hand clenched into a fist, and the vitality in his body gushed out.

The fist slammed forward.

"Poof!"

A sound of breaking the air sounded, and the fist shadow lingered in the space for a long time. The space around the fist was actually slightly distorted and fluctuated.

"What a powerful force!"

"The vitality in the body surges out, and it looks like an entity!"

"My strength has increased at least several times compared to when I was in the Nine Heavens Realm. Even if you don't use your martial arts, this fist will be able to directly kill the Seventh Heaven or even the Eighth Heaven Acquired Realm martial artist. ”

Standing on the bed, Ning Yan felt the tremendous increase in the strength of his vitality after the realm breakthrough.

The power possessed by the innate realm made him a little surprised.

Because he has just stepped into the innate realm, he has not yet fought against other innate realm martial artists. Therefore, Ning Yan still didn't know how strong his combat power was.

In fact, with the strength of the vitality in his body, coupled with the Fallen Leaf Three-Style Martial Arts and the Golden Wheel Star Soul, if he attacked with all his strength, it was enough to confront most of the mid-innate realm martial artists head-on. If he could get a spirit weapon-level or close to a spirit-level weapon, and then master a body martial art, he would be able to defeat many mid-innate realm martial artists, and even in front of ordinary late-innate realm martial artists, he was not completely without the ability to fight.

After feeling the very huge power of the ascension, Ning Yan turned his eyes and looked at the remaining top-grade spirit stones beside him.

Of the original ten top-grade spirit stones, five have not yet been used.

In the past ten or so hours, in order to break through to the innate realm, he had consumed five top-grade spirit stones.

If this matter gets out, it will definitely be jaw-dropping!

How could a martial artist who was not even in the innate realm absorb the energy contained in five top-grade spirit stones in a dozen hours?

Not to mention five, it is unrealistic to absorb one.

Under normal circumstances, if a martial artist in the Nine Heavens Realm wanted to completely transform and absorb the aura contained in a top-grade spirit stone, it would take at least three days to be safe. Even if it is a martial arts genius of the five-ring star soul and the six-ring star soul, it will take about two days.
