Six years ago, when Xia Fan chose the incomplete practice of refining the jade technique, the family elders stationed in the library had persuaded Xia Fan to give up this body refining exercise, because this exercise was too difficult to practice, and no one in Xia Jiabao had been able to practice it successfully.

However, for Xia Fan at that time, the body refining technique of refining jade was the only opportunity for him to become stronger, how could he give up.

It was only when Xia Fan began his first practice of refining the jade recipe that he discovered why the elder said that this exercise book was difficult to practice, and why no one had succeeded in cultivating.

This is the only feeling that Xia Fan feels when he cultivates the jade refining technique, this kind of pain is so strong, if it is an ordinary person, I am afraid that it will make people faint in pain immediately.

The jade refining method is a body refining exercise, which is an exercise to cleanse and strengthen one's own flesh with the true qi in the body, and the true qi passes through the skin and muscles of the whole body, just like a sharp blade added to the body, and the pain is nothing more than Ling Chi torture.

Such pain is not something that children can bear, and the jade refining technique is incomplete, and can only be cultivated to the third level of qi refining, but for adults, it is of no great use, and they don't want to suffer this suffering, so naturally no one will practice.

But Xia Fan is not an ordinary person, Xia Fan has experienced more severe pain than this, and he has endured it for many years.

In addition, Xia Fan was a human being in two lives, and his mental strength and willpower were far beyond ordinary people, stronger than that child and teenager, so although the severe pain was intense, it was not enough to make Xia Fan change color, because he had long been accustomed to it.

However, because of this, Xia Fan was sure that the Jade Refining Technique was indeed a body refining technique suitable for Qi refining martial cultivators, at least a technique suitable for him Xia Fan.

Because the body refining exercises in mortal martial arts could not harm Xia Fan's body at all, nor could they make Xia Fan feel pain, let alone strengthen his physical body.

It was under the continuous strengthening of the jade refining technique, after six years, Xia Fan's physical strength and strength had increased rapidly, and it had reached an inhuman level.

Even if it is a mid-level fourth-layer qi refining powerhouse, its physical strength cannot be compared to Xia Fan, at least Na Shen harmless will not dare to go down to this spirit cave.

Moreover, the jade refining technique also has an excellent repair function, which can quickly repair the flesh tissues that have been affected, which is also the biggest reliance for Xia Fan to dare to go down to the spiritual acupoint and face the strangulation of the spiritual energy whirlpool.

At this time, Xia Fan, who was at the bottom of the spiritual cave and surrounded by the entire spiritual qi vortex, was under the full operation of the jade refining technique, and his body was full of Xuanguang, and he finally resisted the strangulation of the spiritual qi vortex.

However, the infinite aura of heaven and earth frantically poured into Xia Fan's body, and the jade refining technique was powerless to stop it at all, or in other words, the jade refining technique not only did not stop it, but instead absorbed the heaven and earth aura around Xia Fan's body with all its might.

This was done by Xia Fan on purpose, Xia Fan wanted to use this violent heaven and earth aura as the source to promote the jade refining technique to re-strengthen the physical body, and strengthen the physical body to a level that was enough to withstand the entire spiritual qi vortex infusion.

As a result, the tyrannical aura of heaven and earth filled Xia Fan's body, tearing Xia Fan's strong muscles apart, and the meridians exploded.

When the infinite heaven and earth aura rushed into the body, the jade refining technique began to run wildly.

Under the effect of the jade refining technique, the broken muscles and swollen meridians in Xia Fan's body were quickly repaired, and they were renewed, stronger than before.

However, this newborn body was still unable to resist the flushing of the violent heaven and earth aura, and it soon broke again, and the jade refining technique repaired the broken flesh meridians again.

Moreover, the operation of this jade refining technique was no longer driven by the true qi in Xia Fan's body, but directly promoted by the heaven and earth aura that rushed into his body, and because of this, the pain felt by Xia Fan's body was several times more powerful than before, or even dozens of times. ...,

Ever since his physical strength had reached a limit under the effect of the Jade Refining Technique, Xia Fan hadn't felt this kind of painful pain for a long time.

Xia Fan knew that this was because his true strength was too weak to promote the further transformation of the jade refining technique.

Now that Xia Fan felt this feeling again, Xia Fan found that there was a subconscious expectation in his heart, looking forward to how much stronger his physical body would be after today.

····

The spiritual energy vortex in the spiritual cave rotated endlessly, constantly gathering huge heaven and earth spiritual energy from heaven and earth, and entering the spiritual acupoint, without any change due to Xia Fan's absorption.

With the continuous influx of heaven and earth aura, the bloodstains and wounds on Xia Fan's body are becoming fewer and fewer, and they are gradually disappearing.

Obviously, Xia Fan's physical body had been strengthened again under the effect of the Jade Refining Technique, and the strangulation of the Spiritual Qi Vortex could no longer pose any threat to Xia Fan.

At this time, although Xia Fan was tall and ashamed, he was not a muscular type, but his whole body was extremely harmonious, all of them were called the golden ratio, and Xia Fan's skin was like beautiful jade, warm and flawless, which was the origin of the name of the jade refining technique.

The only thing that dissatisfied Xia Fan was that he found that all the hair on his body had disappeared, and under the strangulation of the aura whirlpool, Xia Fan's skin and muscles were shattered, how could that hair still exist.

This is in line with Xia Fan's famous saying in his previous life - if the skin does not exist, the hair will be attached!

Therefore, the current Xia Fan can be described as a real bare person.

However, this obviously didn't bring much sorrow to Xia Fan, feeling his strong body, Xia Fan, whose mind was as hard as steel and unshakable as a rock, couldn't help but be moved and excited.

Xia Fan knew in his heart that now it was this advance failure, and he would not lose anything, Xia Fan obviously felt that his physical body had become more powerful, this was a qualitative change of strength, enough to compete with the strength of the middle-level powerhouse.

However, Xia Fan did not lose his temper because of this, now Xia Fan's physical body meridians are strong enough to withstand the erosion of heaven and earth aura, and he can already gather qi condensate and advance to the fourth level of the middle level of qi refining.

Xia Fan's internal qi refining technique began to run rapidly, causing the heaven and earth spiritual qi in the spiritual qi vortex outside his body to pour into his body at a faster speed.

When these violent heaven and earth aura entered Xia Fan's body, they were constantly refining for the jade refining technique, becoming extremely pure, and under the guidance of the qi refining technique, all of them turned into true qi and integrated into the meridians in Xia Fan's body.

All of a sudden, the meridians in Xia Fan's body were filled with a large amount of pure true qi, and there was still a huge amount of heaven and earth spiritual qi outside Xia Fan's body that surged into the meridians and was transformed into true qi.

However, the meridians in Xia Fan's body were always the same as before, too narrow, only the existence of the size of a gap, how could such a small meridian space accommodate the huge, infinite heaven and earth aura.

As a result, under the oppression of the huge heaven and earth aura, the true qi in the meridians in Xia Fan's body began to be constantly squeezed and shrunk, and became richer, and after a while, all the true qi in the meridians turned from gas-like to a faint trace of mist true qi.

But this is obviously far from enough, a little misty true qi cannot advance to the fourth level of the middle level of qi refining.

Between Xia Fan's mind turning, the Qi Refining Technique worked faster, and a large amount of Heaven and Earth Spiritual Qi was quickly refined into new True Qi and poured into the meridians, transforming into mist-like True Qi under strong pressure.

This repeatedly, with the support of the infinite heaven and earth aura, which lasted for four full hours, Xia Fan finally filled all the meridians in his body with mist-like true qi.

"It's finally time to start!" Feeling the faint feeling of fullness in the meridians in his body, Xia Fan's spirit couldn't help but perk.

Under the guidance of Xia Fan's thoughts, the Qi Refining Technique and the Jade Refining Technique vibrated at the same time, running at the fastest speed, and the infinite heaven and earth aura poured into Xia Fan's body at an even more crazy speed, pulsing towards the surrounding body.

····

"Boom!"

A breath rushed out of the spiritual acupoint, although it was not huge, but it was extremely sharp, and in an instant, it pierced through the spiritual energy vortex and rushed straight into the void, not dispersing for a long time.
