He wiped the sweat oozing from his head, and he looked like he had palpitations.

Qin Yun couldn't help but ask, "What is the use of this spirit jade?"

In Qin Yun's impression, jade jade gemstones are nothing more than luxury playthings for high-ranking officials, nobles, wealthy businessmen, and magnates, and high-grade jade must be valuable, but for a piece of jade to destroy people, it is really incredible.

"For us, there is no difference between spirit jade and ordinary white jade. Qin Liren was shocked: "However, it is the most precious material for qi refiners!"

Qi Refiner! Qin Yun understood a little.

Qi refiners are the most special existence in the vast Kyushu, few in number but powerful.

In many rural legends, the Qi Refiner is a land immortal who can call the wind and rain and scatter beans into soldiers, so he is respected and even admired by countless people.

In fact, Qi Refiners are not omnipotent immortals, they are also mortals, but they have mastered various magical spells and pursued Heavenly Dao immortality.

Refining and refining gas, refining gas and transforming gods, refining gods into voids, and the unity of heaven and man!

There are many similarities between the four realms of the Qi Refiner and the great realm of the martial artist, and the secret techniques are endless.

Alchemy, casting, servant beasts, exorcisms, rune arrays, Qimen Dunjia

Qi refiners have a long tradition and complex origin schools, and the vast majority of qi refiners live in seclusion in the great clans of the sect, the inner courtyard of the palace, or in the mountains and wilderness, and the clouds and seas, and rarely appear in front of people.

A big clan like the Qin clan enshrines a lot of qi refiners, and the pill hall and casting hall of Muyang Dao belong to the territory of qi refiners in a strict sense.

However, although the status of Qi Refiners is transcendent, if they fight for life and death, they are often inferior to real master swordsmen.

In the way of the sword, there is a statement that one sword breaks ten thousand laws, and the "ten thousand laws" referred to include the techniques of the qi refiner.

The spirit jade is the most important material used by the qi refiners to cultivate the secret techniques of the exercises, cast the spirit objects of the magic weapons, and burn the talisman array, and the pure heaven and earth spiritual power contained in the spirit jade is regarded by them as a supreme treasure.

A piece of fine spirit jade or even pixie jade can make qi refiners fight against each other, and it can also make them bow their heads.

This is the preciousness of Lingyu.

The Heavenly City Sword Sect ranks among the top ten sects in the vast Kyushu, and there is naturally no shortage of powerful qi refiners in the sect.

If Qin Yun joined the Heavenly City Sword Sect and used this piece of red blood chalcedony jade to befriend the sect elders, he would undoubtedly be of great help.

Qin Yun didn't take things outside his body very seriously, but when he truly understood the preciousness of the red blood chalcedony jade, he suddenly felt a little uncomfortable in his heart.

This piece of red blood chalcedony jade should have been owned by Qin Liren, but it fell into Qin Yun's hands by mistake.

Although Qin Yun has a clear conscience, since Qin Liren is a friend, it is definitely not his style to monopolize the benefits.

After thinking about it, Qin Yun took out a medicine bottle from the gift bag and handed it to Qin Liren: "I took the red blood chalcedony jade, you can take this bottle of Zhongpin Pei Yuan Dan!"

Qin Liren originally wanted to refuse, but when he heard the words "Pei Yuan Dan", his breathing suddenly became a little heavier.

Pei Yuan Dan's medicinal power and medicinal effect are much better than Pei Qi Dan, and only direct descendants are allocated within the Qin clan, and the children of a side line newcomer like him, unless they exchange a large number of family merits, they can only look at their greed.

This bottle of medium-grade Pei Yuan Dan was enough for him to rush to the second or even third heaven realm of qi refining, and the temptation for him was stronger than that of the red blood chalcedony jade!

But he was embarrassed to ask for such a valuable elixir, after all, Qin Yun had helped him take revenge at night, and the Red Blood Chalcedony Jade Rough Stone was also willing to give it to Qin Yun.

Qin Yun saw Qin Liren's contradictory thoughts, stuffed the medicine bottle into his hand, and said with a smile: "Let you take it, I don't need the pill to cultivate, this bottle of Peiyuan Pill is also a waste to put it here with me, the most important thing is that you hurry up and improve your strength!"

Qin Liren exhaled a long breath, and he held the cold porcelain bottle in his hand tightly: "Brother Qin Yun, thank you!"

This was the second time he had said thank you to Qin Yun in the evening, but this time his gratitude was more heartfelt.

After getting Pei Yuan Dan, he couldn't sit still anymore, and couldn't wait to say goodbye to Qin Yun and leave in a hurry.

Qin Yun could understand his feelings, so he didn't mind.

After closing the door, he took the red blood chalcedony jade out of the animal skin bag and played with it in his hand repeatedly.

The myelic jade is gentle and delicate in the hand, although it has not been carefully polished and carved, but the magnificence of this heaven and earth creation condensed for thousands of years is breathtaking, and Qin Yun can hardly take his eyes off it when he looks closely.

His soul seemed to be attracted by the red blood chalcedony jade, and he couldn't take his eyes off how long he had been looking at it.

Suddenly, Qin Yun felt a fluctuation coming from the sea of knowledge, and suddenly came to his senses under the shock.

Scary!

Qin Yun subconsciously held the red blood chalcedony jade firmly in his hand, and he didn't dare to look at it anymore.

At this time, the red blood cedony jade suddenly revealed a strange aura, pouring into the acupoints of his palm and reaching the martial veins, and quickly rushed up towards the sea of knowledge!

What's going on?

Qin Yun couldn't help but be taken aback, but he didn't panic, because this breath derived from the elixir jade was mellow and warm, and it didn't bring him the slightest harm when it entered his body.

On the contrary, the meridians where the breath goes are extremely comfortable, and the warmth is like being in a hot spring.

However, after all, this is an alien force, and it has invaded the sea of knowledge, so Qin Yun can't be careless.

Just as Qin Yun was about to throw the red blood chalcedony jade aside, the influx of aura suddenly became turbulent, and he instantly entered the sea of knowledge.

But the worst case scenario did not appear, the Qiankun Heaven Replenishing Stone entrenched in the sea of Qin Yunzhi emitted a trace of golden light, and the surrounding Yin and Yang Qi rings swirled and expanded, swallowing the invading myelic jade aura like a long whale absorbing water.

Thousands of stardust shone brightly, and the Great Freedom Sword Intent Silver Dragon, which was floating and wandering in the aura of air, actually faintly emitted the sound of a dragon's groan!

The strange situation that appeared in the sea of knowledge made Qin Yun immediately calm down, he did not go to stop the Qiankun Heaven Replenishing Stone from devouring the myelic jade aura, but sat cross-legged on the ground, concentrating on guarding the dantian.

The breath of the red blood chalcedony jade was endless, and the Qiankun Heaven Replenishing Stone did not refuse, until the moment when the Yin and Yang Qi Ring Starlight was at its peak, a majestic and vast force poured out and rushed into the martial vein!

Qin Yun suddenly blessed his soul, and without hesitation, he used his mental method to urge his true qi to meet it.

When the two forces converged and blended together, Qin Yun controlled the new power to circulate his limbs and hundreds of remains, penetrating through all the opened acupoints, and marching towards the blocked meridians.

One by one, the meridians and acupuncture points were penetrated like a bamboo, and there was no slightest obstacle or difficulty, this kind of freewheeling pleasure made Qin Yun almost want to raise his head and roar.

However, with amazing perseverance, he suppressed the fluctuations of his mood and methodically attacked the inner fortresses one by one.

Eighteen points of both eyes, through!

Twelve acupoints in both ears, through!

Ten points of mouth and nose, through!

Qin Yun gradually came to his senses.

The breath of the red blood chalcedony jade should be the heaven and earth spiritual power it contains, but I don't know what reason it was triggered, causing it to pour into the body and be devoured and absorbed by the Qiankun Heaven Replenishing Stone.

And Qiankun Mending Heaven Stone did not forget his master while enjoying the feast, and fed back with strength.

The last big head hole, through!

Qin Yun was shocked, his hair stood up at the zenith, and the seventy-two acupuncture points were agitated in unison, and the true air flow was connected together, building a new Zhou Tian small circulation!

The third to fourth heavens of the Qi Refining Realm were a hurdle, and it was very difficult to penetrate the seventy-two acupuncture points in the head, even with the help of high-grade pills, it would take at least a year or even a few years of hard work to break through.

However, by chance, Qin Yun actually penetrated all the meridians in a moment and a half, breaking through from the third heaven of qi refining to the fourth heaven in one fell swoop.

It's not just luck!

Rumble!

Before Qin Yun could rejoice, the huge power gushing out of the Qiankun Mending Heaven Stone suddenly lost control and rushed wildly through the meridians.

Qin Yun only felt like he was in a purgatory oven, and the membranes, muscles, and bone meridians all over his body seemed to be torn to pieces in an instant, bringing unimaginable pain.

It would be happy if he could faint at this time, but his mind was extremely clear, and he could only grit his teeth and support it, resisting the invasion of pain.

Because he understands that once he loses his sanity, then it must be the result of no return!

The hot red skin oozed sweat and evaporated instantly, the bulging muscles couldn't help but twist, the ravaged and ravaged muscles and bones made a crunching sound, and a wisp of red blood overflowed from the corner of Qin Yun's mouth.

The amazing perseverance honed by repeated life and death helped Qin Yun persevere, and the stubbornness in his bloodline that never bowed his head and surrendered to defeat supported his backbone until

Boom!

With a muffled sound, the red blood cedony jade in his hand turned into powder.

As soon as the light and flame of the Qiankun Heaven Replenishing Stone in the sea of knowledge converged, the terrifying power that surged out disappeared.

The yin and yang aura returned to its original state, and the sea was undisturbed, as if nothing had happened.

It's just that the silver dragon composed of the sword intent of the Great Freedom Sword is becoming more and more handsome and extraordinary, and the edge looms between the wanderings!

"Ugh!"

Qin Yun lay on his back on the cold floor, there was no part of his body that was not sour or numb, and the whole person collapsed to the point that he couldn't even move his little finger.

Sweat soaked through the clothes, dilated pores oozed greasy dirt, and a foul smell slowly filled the room.

But after going through the great painful ordeal, Qin Yun now feels like he has been reborn in Nirvana, as if every inch of his muscles and muscles have been reborn, and he is giving out a hearty cheer!

Strength, little by little, regained within him.

After a long time, Qin Yun got up again from the floor.

He was surprised to find that his body seemed to have risen a little taller, and the muscles of his body had become flat and flexible, and they had never regained their rigidity and solidity.

The surface of the skin was covered with a layer of oily black dirt, so filthy that Qin Yun himself felt sick.

He hurriedly went to the bathroom to fetch water, took off his clothes and rinsed them up and down several times.

After washing it clean, Qin Yun couldn't help but be secretly surprised when he saw that his skin had actually become a lot fairer, and it was faintly revealing a crystal warm luster.

What's going on here?
