After the heavenly flame disappeared, the top of Tushan Mountain was covered by cold.

Those who are slightly weaker in cultivation will be injured by the cold and evil if they stay at the top of the mountain for a while.

The Thousand Demon Sand Sea is also densely covered with dotted green flame lotus fires, which are difficult to eliminate for eternity, so that the Thousand Demon Sand Sea continues to remain dry and hot, but the thousands of mountains and mountains north of Tianzhu Peak have been completely covered with ice and snow in the past year.

The thick ice under the white snow is getting thicker and thicker day by day, and countless plants and trees, as well as birds and beasts that have been frozen to death, are also completely frozen under the ice.

However, just south of Tianzhu Peak, between the ice and snow, there is an active volcanic crater, which was once the habitat of the Firefox clan.

This active crater, three hundred miles southwest of Yuzhu Peak, was originally hidden underground and connected to the snake cave.

When the Demon Dragon Qianyu broke out of Yunzhou, this active volcano was a little farther away and was not completely destroyed, but the mountain, which had originally covered the crater and was much more fragile, collapsed and buried the live crater.

Over the years, blazing fire has been spewing out from the cracks of the collapsed mountain, forming a desperate valley with extremely hot and no vegetation in the ice and snow......

Chen Xun set up a ban around him to prevent others from accidentally breaking in, and then walked into the valley with Chi Songzi, Hu Taiyan, and Ji Lie.

With great magical powers, the four of them took a lot of effort to move the collapsed mountain away, revealing the crater of magma surging.

The crater rim had collapsed, and a little magma had flowed out to resolidify into hard rock, and Chen Xun and the others stood in the crater, less than a hundred feet away from the surging magma.

The blazing flame current, the light above the crater were violently distorted, and the dark red flowing fire between the magma was not necessarily weaker than the blue flame of the sea of flames.

With Chen Xun's cultivation, when he got closer, he still felt that the heat was unstoppable, and the skin on his body was about to be scorched; Ji Lie and Chi Songzi were also cautious, afraid that they would inadvertently trigger a magma eruption, and it would be difficult for them to retreat at that time.

Chen Xun took out the Void Yuan Bead and released the Void Yuan Palace, from small to large, seeing the wind, it soon appeared in its original form, and landed steadily on the surging hot magma.

In the next moment, the incomparably fierce blazing flames all merged into the Xuyuan Palace, forming a thick red glow all around.

Ji Lie, Gu Wentian, and Chi Songzi had long known about the Xuyuan Palace from Chen Xun's mouth, but today they had the opportunity to see the full picture of the Xuyuan Palace.

The crater is two or three thousand zhang wide, and it is just enough to put it into the Xuyuan Palace.

They were all shocked by the magnificence of the Chiyang Palace, but in terms of scale alone, the Xuyuan Hall was hundreds of times larger than the Chiyang Palace, and they really didn't know what kind of earth-shattering treasure the Xuyuan Hall was intact.

"This ancient hall is all made of Yuan copper!" Chi Songzi said in shock as he approached and touched the Xuyuan Palace.

Chen Xun is good at refining weapons, of course, he heard of Yuan Tong.

Yuan copper, also known as red essence copper, often when a red essence copper mine is exhausted, a small amount of red essence copper will occur at the bottom of the vein.

Magic weapons above the ground level are often used to refine the forbidden core of red essence yuan copper.

Only a material like Red Essence Yuan Copper can refine those precise and mysterious multiple formation prohibitions in square inches.

Inferior materials, even if you can barely refine multiple formation prohibitions, but don't talk about resisting enemies, once you absorb a huge amount of aura, the forbidden core itself will not be able to withstand it and collapse......

Kui Long Pavilion did not yet have the ability to refine earth-level magic weapons, and Chen Xun had only heard of Red Essence Yuan Copper before, but he had never seen it.

He had always thought that the Xuyuan Hall was made of copper similar to red essence copper, but he didn't expect it to be red essence yuan copper.

Purely in terms of output, a vein that can store more than 100 billion catties of red refined copper may not be able to smelt 350,000 catties of copper.

Listening to Chi Songzi, the entire Xuyuan Hall is likely to be cast with red essence yuan copper, Chen Xun's first thought was to dismantle the Xuyuan Hall and sell it in pieces.

It's a pity that even if the prohibition of the Void Yuan Hall is nine out of ten, if you want to demolish it, you need to cultivate in the early stage of the Nirvana Realm, and Chen Xun is far from having this ability......

"What kind of magic weapon is this Heavenly Domain, how can there be such a huge amount of Red Essence Yuan Copper?" Chi Songzi said in shock.

The old Kui Yuan God condensed into a human form, appeared in front of everyone, and said: "The Void Yuan Hall was made from a whole huge copper mountain in the ancient times......

Listening to Kui Long's words, Xuan Yanjue has another secret method of refining Yuan Copper from Red Essence Copper, but if you think about it with your toes, you can understand that the conditions for obtaining Red Essence Yuan Copper with this secret method must be extremely harsh, and it is not something that the four sects can have at this time.

Ji Lie and Gu Wentian didn't break the casserole to ask in the end, but they couldn't imagine that under the secret cave of Yuzhu Peak back then, there was such a bronze hall hidden.

Chen Xun opened the ban, and entered the interior of the Xuyuan Hall with Chi Songzi, Ji Lie, and Gu Wentiantong.

After absorbing the flame flow, there was not much heat inside the Xuyuan Palace, giving people a feeling of being like spring and Mu Xiyang, and there were wisps of pure and pure Xuanyang aura leaking out from the four walls, and the red pine nuts confirmed that the violent flame flow ejected from the volcano was indeed absorbed by the Xuyuan Palace.

Gu Wentian sighed with emotion: "If the Void Yuan Hall can swallow the Tu Mountain Heavenly Flame, maybe it won't take a thousand years, and it will be repaired as before, right? But then again, if you really have to bring the Void Yuan Hall into the Tu Mountain Peerless Ridge to refine the Heavenly Flame, I'm afraid that the sects of Yunzhou would have already set off a bloody storm for the Void Yuan Palace......

Lao Kui smiled, he and Chang Zhen were full of wariness of the monks of all the sects in Yunzhou in the past, and it was too late to hide the traces, where did he dare to take the Xuyuan Hall to Tushan Peerless Mountain to refine the Heavenly Flame?

With such a big move, how could it be possible to hide from the many sects in Yunzhou?

Before the prohibition of the Xuyuan Hall was completely restored and re-established as a pure yang dao weapon, there were no other valuable treasures in the inner hall except for a Xuanyuan Bible.

For now, the Void Yuan Hall is really the four sects that must be protected thoroughly, and there can be no one little bit of a mistake.

Once the news leaks out, there is not much problem for the Xuyuan Hall to fall into the hands of Popes such as Cetianfu or Xuandu; if the demon clan is allowed to go, not only will Yunzhou be catastrophic, but it is also very likely to harm the Changzhen clan.

On the Canglong Spine, if Chen Xun went out to look for opportunities, only a few Tianyuan Realm cultivators such as Lei Wanhe and Su Lingyin and Zuo Qingmu and other refiners remained, and their strength was still a little weaker.

In the future, there may be more than one or two forces eyeing Kuilong Pavilion.

Chen Xun thought that if the Xuyuan Hall continued to stay in Canglong Ridge, there would be too many uncertain factors, and this time he transferred to Tianzhu Peak, hoping to hand it over to Master Chisong to directly guard the ancient hall.

The Vajra Taixuan Sutra, the Kui Long Alchemy Technique, the Condensing Mantra, the Nine Tribulations Refining Body, the Dragon and Tiger Pill Formula, and other Dao Recipes, Chen Xun could take out the Dao Recipes, and he took them out and shared them by the four sects.

The third layer of the Xuanyan formula, Chen Xun had just begun to comprehend, but he used the past half a year to copy all the third layer of the method.

Chen Xun's so-called "transcription" is actually to use the rubbing technique possessed by Kui Long's alchemy to copy the recipe, but the secret method of the third layer of the Xuanyan recipe is extremely profound and complicated, and it is rubbed into more than 800 volumes of silk books, so Chen Xun spends so much time just by browsing, reading, and transcribing.

The part involving refining weapons was handed over to Zuo Qingmu for preservation and enlightenment, and the part involving sword cultivation and Yuan Shen cultivation was handed over to Chi Songzi, Ji Lie, and Gu Wentian for preservation, as the secret transmission of these three sects......

In the battle of the Thousand Demon Sand Sea, the disciples of the four sects suffered heavy casualties, but the casualties of the core disciples were quite small, and the most critical factor was that Chang Zhen had dismantled more than 100 bottles of Star Iron Demon Bodies in the past ten years, and took the formation prohibition that was still intact in the demon body, and refined more than 500 ground-level magic weapons, so that the core disciples of the four sects almost all had one or two ground-level magic weapons.

The benefits of the Xuyuan Palace, the four sects have all enjoyed, after Chen Xun left Wushan, he naturally handed over the Xuyuan Hall to the four sects to jointly guard.

"Why don't you retreat in Wushan, and then travel the world after cultivating the Yuan Dan?" Gu Wentian asked Chen Xun puzzled.

Chen Xun had already cultivated to the consummation of the Tianyuan Realm, there was no substantial obstacle to cultivating the Yuan Dan, and he had a very good chance of cultivating the Yuan Dan after twenty or thirty years of retreat, and the four sects also had the strength to ensure that he would not be disturbed during his retreat.

Chen Xun is alone, where can there be an undisturbed retreat for him for twenty or thirty years?

Chen Xun smiled, and at this time he had no intention of telling the secret of his Xuanyuan Holy Body, and said: "Master Chisong said that my cultivation is not in the sect, I think I should go out and find my Dao fate......

Chi Songzi nodded, when he participated in the Haoran Heavenly Dao, he did get a glimpse of the heavenly opportunity, so he also refused Chen Xun to join the Shenxiao Haoran Sect at the beginning.

But why this is so, the heavenly machine is unpredictable, and he can't peek at it.

Chen Xun has his troubles.

No matter who it is, if you cultivate Yuan Dan, heaven and earth will be out of phase.

According to the quality of the Yuan Dan cultivated, the small phase will alarm a radius of hundreds of miles, and the large one will alarm a radius of thousands of miles, and it may even alarm a radius of thousands of miles......

Chen Xun wanted to cultivate to the consummation of the Yuan Dan realm, it was not a matter of cultivating a Yuan Dan.

If he stays in Wushan for retreat, forming Yuan Dan one after another, and giving birth to the different phases of heaven and earth, isn't this telling the people of the world the secret that he has the Xuanyuan Holy Body?

Chen Xun wanted to cultivate the Yuan Dan, either he would go away from home, hide and find a place where no one knew and was inaccessible to cultivate, or he would wait until the spiritual energy in the Void Yuan Bead was sufficient for him to hide in the Void Yuan Bead to cultivate......

After refining hundreds of thousands of demons, the Void Yuan Spirit Land had expanded to a radius of one hundred and fifty zhang, but it was far from enough for him to hide in it for more than ten years and cultivate the Yuan Dan.

He wanted to cultivate Yuan Dan, so he could only leave Wushan.

Chen Xun also taught Chi Songzi the method of entering and exiting the Void Yuan Hall and opening the forbidden trial.

They walked out of the Void Yuan Palace, re-used their supernatural powers, and carried the collapsed mountain stones to cover the Void Yuan Hall and the crater.

In the following March, the four of them went into retreat here, saying that they were contemplating the Dao of Enlightenment and Sealing, but in fact, they used lava and other techniques to melt and re-solidify these collapsed mountain stones into new solid rock formations, forming a stone mound three or four hundred zhang high on top of the Void Yuan Secret Temple.

A large amount of flame flow from the volcano in the belly of the earth, although it was absorbed by the Xuyuan Palace, there was also a large amount of Xuanyang aura from several stone eyes, and from then on, this side was a forbidden place for cultivation in the Shenxiao Sect.

As long as the Divine Night Haoran Sect is not destroyed, there is no doubt that anyone will discover the secret of the Void Yuan Palace......

The mind of the Xuyuan Hall was temporarily settled, and Chen Xun returned to Canglong Spine from Tianzhu Peak.

After the Xuyuan Hall was moved, the underground of Wushan City at this time formed a dungeon with a height of hundreds of zhang and a width of more than 2,000 zhang.

After more than ten years of continuous smelting, a solid rock layer dozens of zhang deep has been formed on the underground palace.

More than 100 rune lamps are embedded in the stone wall overhead, illuminating the underground palace as bright as day.

This underground palace itself is a spiritual cave shaped by a heavenly horse stepping on the ground, and there are seven spiritual veins connected with the spiritual energy, and the spiritual energy of the underground palace is abnormally abundant and pure.

If it weren't for the Xuanyuan Holy Body, the underground palace would be an excellent place for Chen Xun to retreat and cultivate the Yuan Dan.

Chen Xun stood in mid-air, looking at the stone walls around the underground palace, thinking that he was about to leave Wushan, which he had worked so hard to manage, and he was also full of emotion in his heart.

After the battle of the Thousand Demon Sand Sea, Chen Xun obtained a total of fifteen little demon generals' primordial gods, including Snake Wuxin and Chihai, he needed ten more to make up the Xuanyan battle array, and the excess was handed over to Lei Wanhe, Su Lingyin, Zuo Qingmu and others to cultivate the second primordial god and incarnate outside the body.

Zuo Qingmu and the others left, and Jiang Bingyun and Qingxuan came in from the secret passage and stood silently behind Chen Xun.

Although she did not cultivate the Plain Girl Jade Pill Technique, Qing Xuan had been unable to break through the bottleneck after the Battle of the Thousand Demon Sand Sea, and successfully cultivated her divine consciousness within a few months, and advanced to Tianyuan again......

When it comes to cultivation, qualification and mind are two equally important factors.

Zong Ya, Gu Jianfeng and the others may not be stronger than Qing Xuan in terms of qualifications, and the bloody wind and rain they have experienced over the years have tempered their minds that are far purer and more indestructible than Qing Xuan, so their cultivation at the Divine Soul level is extremely fast, and they almost have not encountered much bottleneck.

Qing Xuan experienced the battle of the Thousand Demon Sand Sea, and there was a great breakthrough in his heart.

After the war, many of the disciples of the four sects broke through the previous bottleneck and entered a new realm.

"I don't know how many years I will see you again, but after I cultivate the Spirit Yuan, I will continue to cultivate the Plain Girl Jade Pill Formula......" Qing Xuan opened her clear and beautiful eyes, boldly saying the affection in her heart.

Chen Xun turned to look at Jiang Bingyun and Qing Xuan's stunning and charming faces, stretched out his hand to caress Qing Xuan's smooth face, and said, "I thought you would accompany me tonight." ”

"Don't. Qing Xuan couldn't resist Chen Xun's shamelessness, and lowered her head shyly.

Although her heart was also full of affection, she maintained a pure yin body at this time, which helped her to cultivate the spirit yuan and advance to the Tianyuan realm, and also helped her to cultivate in the future of the Tianyuan realm.

Restraining the love of men and women for a while is actually a longer companionship in the future.

"Then you can stay with us tonight. Chen Xun said again.

"......" Jiang Bingyun glared at Chen Xun with disgust, he didn't expect him to be shameless like this, knowing that Qing Xuan couldn't break the pure yin body, and left Qing Xuan to "watch the battle", how could she hold her head up in front of Qing Xuan in the future?
