Canglongji gathered soldiers and horses in less than half a year, in addition to the tent camp, only a limited number of stone halls were built, one of which was the Kuilong Pavilion, which was heavily guarded.

The refining weapon of the clan of the sect is either borrowed from the earth fire, or the refining furnace is originally a huge magic weapon, which can gather the qi of Xuanyang and smelt the golden stone. Regardless of borrowing the earth fire, the refining furnace is arranged on the Xuanyang spiritual veins and spiritual acupoints, and the refining tools are all important tasks of the sect, and outsiders are never allowed to interfere and snoop, and most of the refining rooms are built in the underground palace.

When Canglan City was not destroyed, the refining place of the school palace was also built under the belly of the Dragon Binding Mountain.

Walk into the Kuilong Pavilion, another courtyard enters the underground palace, walks through a long underground corridor, enters a huge underground grotto, and opens up more than 20 refining rooms on one side of the grotto.

Accidents occur from time to time in refining, and ordinary sects will set up small forbidden magic circles in the refining room, and Kuilong Pavilion is no exception.

Su Junyuan walked in and noticed that there was a thin film of water on the four walls of the grotto, which made people's hearts feel cool.

Su Junyuan thought of what Qingfeng and Su Fanglong said about the situation when Chen Xun guarded the Dragon Pool, and asked in surprise: "The magic circle here was withdrawn from the Dragon Pool?"

Chen Xun nodded and said, "Yes, we don't have a more powerful magic array in our hands, so we can only use the Xuanshui array to make do with it for the time being......"

Su Junyuan smacked his lips, he didn't think that the Xuanshui Array was not strong enough, but he felt that Chen Xun actually used the magic array that could resist the strong attack of Yuan Dan Zhenren to seal the refining room, which was a bit too big and too useless.

Su Junyuan followed Chen Xun and them into a refining room, and the moment the refining room was opened, Su Junyuan felt that the hair on his body was almost burned by the Xuanyang Yuan Qi that came through.

Su Junyuan thought of the situation where the Xuanyang Spirit Acupoint under the Jade Pillar Peak collapsed and the Xuanyang Fire Pillar rose to the sky.

At that time, a Tianyuan elder of the Xuanhan Sect was unexpectedly engulfed by the Xuanyang Fire Pillar that rose from the ground of the Jade Pillar Peak, and his body disappeared in an instant, he thought to himself that this Xuanyang Spiritual Vein was not slightly worse than the Xuanyang Spiritual Sky of the Jade Pillar Peak, no wonder such a powerful sealing array was set up to prevent accidents.

The spiritual veins are usually very deep underground, covering thousands of zhang or even tens of thousands of zhang deep rock formations, which are extremely difficult to destroy by external forces, but they are not impossible.

The Earth Fire Molten Cave and the Xuanyang Fire Cave, if they are not prevented and destroyed by the enemy, the destructive power caused by them is extremely amazing.

Chen Xun told Su Junyuan about the situation in the refining room.

The refining room they entered was responsible for refining the most critical thunder seal artifact of the Xuan Thunder Array.

Although it had not yet reached the standard of a medium-sized mountain protection array, the power of the Xuanlei Array was several times stronger than that of the Four Pillars Mountains and Rivers Array, and the Xuanshui Array were the two strongest arrays that Chen Xun and the others could refine in batches at this time.

Xuan Lei Array, as a magic circle that is far stronger in attack than in defense, is more suitable for casting Xuan Lei chariots and charging into battle.

The Xuanlei Array, plus the Gathering Spirit Core, is composed of a total of twenty-nine complete sets of magic weapons, which is much larger than the Four Pillars Mountains and Rivers Array.

In order to forge the Xuanlei Battle Array, Chen Xun and the others tried to use red black gold instead of red refined copper to refine a more elaborate set of magic weapons, and the difficulty of refining was naturally doubled.

Zhou Yang already knew all the refining methods of the Xuan Thunder Array at this time, but he was not completely sure of the key components such as the Thunder Seal and the Spirit Gathering Core.

Listening to Chen Xun's introduction, they will be able to refine a Xuanlei Battle Array in almost half a year at this time, and after three or five years, after the entry of more than 300 disciples who have just practiced Xuanyan Jue and learned alchemy, the refining speed will increase exponentially, Su Junyuan also faintly has some expectations in his heart, thinking that if ten years later, Canglan can have thirty Xuanlei chariots and hundreds of thousands of Qingyan Lotus Arrows, maybe he can fight for a glimmer of life, right?

Thinking of the scene when the demon dragon broke through the world, the little hope that ignited in Su Junyuan's heart was quickly extinguished.

The Xuanlei Chariot uses the Spirit Gathering Core to gather the aura of heaven and earth, and its power is more than half weaker than that of the Spirit Vein Deployment, and the six to eight Xuanlei Chariots of the Imperial Envoy of the Rebirth Realm are comparable to the peak powerhouses of the Tianyuan Realm.

And in the face of the hundreds of millions of monsters pouring in, even if Canglan had thirty Tianyuan Realm peak powerhouses, what was the chance of winning?

What's more, when the time comes, Canglan will be able to have more than 200 rebirth realm cultivators to charge into battle in the Xuanlei chariot?

If all the low-level monsters that came from the spatial passage, they might still be able to rely on the defensive array to strengthen for a while, but Su Junyuan thought of the scene when the demon dragon broke into Yunzhou, and his heart was still deeply angry.

When he was about to come out of the refining room, Su Junyuan couldn't help but ask Chen Xun: "Ten years later, if there are more innate monsters of the two-headed demon dragon breaking into Yunzhou, will we be completely helpless?"

Except for Zhou Yang and Zuo Aoki, there was no one else, Chen Xun said to Su Junyuan:

"Some secrets don't tell you, it's not that you don't trust you. None of us can fall into the hands of monsters, and then life and death will not be under our control, and the secrets in the depths of the soul are impossible to hide for demon-level monsters. Once the secret of the Jade Pillar Peak Secret Cave is leaked out, it is very likely that the Canglan will overturn in an instant, and there is no possibility of saving it......"

Su Junyuan saw that Zhou Yang and Zuo Qingmu obviously knew the fundamental secret of the secret cave of Jade Pillar Peak, and wanted to ask Chen Xun why he confirmed that the two of them fell into the hands of the monster, so they would not be dug out of the secret of Jade Pillar Peak by the monster from the depths of their souls?

Zuo Aoki looked at Su Junyuan's expression and said, "Elder Zhou and I have both refined a drop of Destiny True Blood into the Soul Lock Seal. If we are unfortunate enough to be captured by monsters, the Soul Lock Seal will destroy our Divine Soul as soon as possible, and there will be no chance that the secret of Jade Pillar Peak will be leaked......"

Su Junyuan was stunned, the art of locking the soul seal can only be refined by the Yuanwu Marquis Mansion, locking the souls of others, in fact, it is to hold the power of life and death of others in his hands.

Su Junyuan was not afraid of death and guarded the White Wolf City, but he did not expect to be completely loyal to Chen Xun.

When he was about to walk out of the refining room, Su Junyuan thought again, he had more than ten years left to live, if he didn't want to be made by Chen Xun to do things against his will, it would be a big deal to cut himself at that time, so he stopped and said:

"If possible, I still want to know what secrets are hidden under the secret cave of Jade Pillar Peak. ”

Chen Xun directly broke into a section of the stone wall, and Su Junyuan knew that the stone wall in front of him turned out to be a phantom array.

"It's both true and false, the ban has not been opened, even Yuan Dan real people can't break through this rock formation. Zuo Aoki smiled and asked Su Junyuan to go first.

Su Junyuan thought that behind the stone wall was another narrow space, and suddenly stepped into a bronze hall that was more than a hundred feet high, and the huge drop made him almost stumble and fall to the ground when he was at the peak of the fetal realm.

Looking up at the huge dome of the bronze hall shining with endless spiritual light, he was dumbfounded, it was hard to imagine that Yunzhou had such a huge copper hall.

Su Junyuan had been speculating about the inheritance of the secret cave of Yuzhu Peak before, which was likely to be the Law Phase Realm, or even the Heavenly and Human Realm, but he couldn't associate it with the giant hall in front of him even after racking his brains.

Innate gods and demons!

The previous owner of this giant hall must have been another innate god and demon, and only an innate god and demon would reside in such a huge bronze hall!

Su Junyuan couldn't see through how strong this giant hall was, but he knew that it was definitely stronger than the Pure Yang Dao Weapon in the ordinary sense.

Su Junyuan didn't say a word, opened his mouth and spit out a drop of life yuan true blood, and asked Chen Xun to refine it into the soul lock seal, he knew in his heart how amazing this secret was, how terrifying it was, and what kind of catastrophe would be caused by the slightest leakage.

He knew this secret, and if he was unfortunate enough to leave the hands of the monsters, the best way was for Chen Xun to lock the soul seal with them here, and directly kill his divine soul.

Chen Xun refined the soul lock seal with Su Junyuan's true blood, and threw it towards the top of the hall, and Su Junyuan suddenly found that he didn't know when, a dragon hovered on the top of the hall and swallowed the soul lock seal in one gulp.

"This is Lao Kui, since the Void Yuan Hall fell into Yunzhou 10,000 years ago, he and another Chang Lao Monster are both guards of the Secret Palace," Chen Xun said, "The main formation of the Void Yuan Hall is forbidden, and it is no longer able to exert its power, but it is a burden that cannot be thrown away." I'm not worried about the Void Yuan Hall falling into other sects. Whether it falls into the hands of the Xuantian Sect or the Longmen Sect, they just want to obtain a stronger Dao tradition or a stronger Dao weapon from it, and even if it falls into the hands of the Yuanwu Marquis Mansion, they use it to fight for imperial power, and they will not destroy Yunzhou to the world. And even if the Void Yuan Hall is damaged like this, it is a hundred or a thousand times more powerful than any pure yang dao weapon known to Yunzhou, once the news leaks half a point and spreads to the Thousand Demon Realm, even if the remaining bones are not returned, there will definitely be stronger Demon Lords and Demon Emperors who directly tear open the void and enter Yunzhou to snatch this thing. And these Demon Lords and Demon Emperors all have the ability to refine and repair the Void Yuan Palace, do you think about how strict the consequences will be......"

Su Junyuan was stunned for a long time before he could barely digest this amazing fact.

After a long time, Su Junyuan asked suspiciously: "Why do you want to tell me about this? I am about to end my life, I have ten years left to live, and I have no hope of advancing to Tianyuan in this life, so I don't look like a person who is plotting big things?"

Chen Xun knew that Su Junyuan was thoughtful, and said, "I have a plan, and I need you to trust me unreservedly?"

"What plan?" asked Su Junyuan.

"I and Chang Lao Wei can use secret methods to melt other people's souls without harming their spiritual sense...... Chen Xun said.

"How can there be such a secret method?" asked Su Junyuan in surprise.

Chen Xun practiced puppetry, and there were few people in the Northwest Regions who didn't know it.

The most critical part of puppetry is to refine the souls of humans and beasts into elite war spirits to drive puppet soldiers.

The spirit battle soul has no self-awareness, it is completely just a puppet soul, and no monk wants his soul to be refined into a spirit by others.

And if you can refine the souls of others without harming your spiritual sense and wisdom, isn't that equivalent to helping others cultivate the original spirit?

How could the world be in such a secret method?

Why are the Tianyuan Realm and Yuan Dan Divine powerhouses so rare?

It is difficult to cultivate the divine consciousness, the spiritual soul, and the Tao.

And whether it is spiritual power, spiritual power, or Dan Yuan, as long as there is enough time, as long as there is enough spiritual energy cultivation, as long as there is enough time, it is just a water mill.

If Chen Xun could cultivate the Yuan Shen for others, it would mean that he would be able to help all the Returning Realm cultivators break through the obstacles to entering the Heavenly Yuan.

Cultivation in the world, where could there be such a cheap thing?

"This kind of secret method naturally has great limitations," Chen Xun said calmly, "With your cultivation, this kind of primordial spirit forcibly shaped by external forces, because you don't want to lose your own spiritual sense, you can't fuse other people's souls to strengthen it, and the cultivation of the soul will not be enhanced, and the forcible separation of the spirit and flesh will leave a hidden disease, at most twenty years later, the hidden disease will break out and the original spirit will collapse, and it will be difficult to be spared......"

"Compared to the longevity I will end, I can live for ten more years, it doesn't matter," Su Junyuan asked suspiciously, "It's just forcibly shaping the Yuan Shen, and the cultivation of the soul and spiritual power can't be improved, what's the point?"

"Because there is a kind of battle formation that requires twelve people with the same heart and soul to practice, and there are also twelve sets of Xuanyan spirit armor, which need to be cultivated into the imperial envoy of the primordial god to exert unimaginable defensive power, and you kind of fake primordial god can also do it," Chen Xun said, "When the time comes, you will be trapped in hundreds of millions of monsters, and the combat power will not seem to increase much, but unless the other party has the strength of the Law Phase, it will be impossible to break the battle array composed of the twelve of you!"

Hearing Chen Xun say this, Su Junyuan couldn't believe it or not.

When he saw this secret hall, he really didn't know what treasures Chen Xun couldn't take, and thought to himself, if the primordial gods of the twelve people were forcibly shaped by external forces, Chen Xun would naturally have a secret method to make their twelve hearts and minds directly communicate, and seeing this hall, he also believed that there must be more treasures hidden in the hall, which could help them resist hundreds of millions of monsters......

Coming to Canglongji, Su Junyuan didn't have any expectations for the battle in ten years, and at this time, he couldn't help but want to grab Chen Xun's arm, and asked, "How many sets of this kind of spirit armor are there?"

Seeing Su Junyuan's eyes shining, Chen Xun smiled bitterly: "I would like to have 180,000 sets, but unfortunately, I can only pull out a dozen sets from the Star Iron Demon Body......"

Chen Xun took out a bottle of Star Iron Demon Body from the Void Yuan Bead and showed it to Su Junyuan.

There were a total of one hundred and forty-four bottles of the Star Iron Demon Body, but most of them were damaged by Yan Zhan, and almost all of them were damaged by the most core formation prohibitions.

Over the years, Chen Xuncai has repaired two bottles of Star Iron Demon Body.

It is precisely because the Star Iron Demon Body is too powerful, even if it is refined into the essence of the Demon Snake Yuan Shen, it can be barely driven, and it does not make much sense to use it to defend against the enemy, and it is very likely to expose the secret of the Void Yuan Palace, which is only used as a shell for Lao Kui and Chang Zhen to attach at this time.

Regarding the destruction of Yan Zhanng's Star Iron Demon Body, Chen Xun's attitude was to demolish it.

The internal structure of the Star Iron Demon Body is, in the final analysis, a delicate and esoteric puppet array.

If the core formation prohibition is damaged, then the formation prohibition that is not damaged will be removed.

Even the most inconspicuous formation prohibition of the Star Iron Demon Body is extremely complex and mysterious.

Others can't dismantle these formation formations, but the Star Iron Demon Body is all refined by Chang Zhen himself, and with Chang Zhen here, it is not difficult for Chen Xun to figure out the effect of these formation prohibitions and refine them into new magic weapons.

Refining the prohibition of defensive attributes into spirit armor and chariots is comparable to the top-level earth-level magic weapons, and refining the prohibition of attack into Xuanbing, or asking Chang Zhen old monsters to take action, and prohibiting these formations into Xuanyang Quadrupole Array and Xuanyang Quadrupole Array, is not an unimaginable thing......

After Chen Xun said his plan, if Chang Zhen's body was not damaged, he would definitely squirt a mouthful of blood in protest first.

These Star Iron Demon Bodies were treasures that he had saved for tens of thousands of years, and he was full of hope that Chen Xun would be able to repair them one day, where did he think that Chen Xun's defeat would be outrageous?

This bottle of Star Iron Demon Body is comparable to the top Heavenly Rank Treasure, and after it is repaired, with the second-layer Xuan Array Battle Array Diagram Imperial Envoy, even the Demon Dragon Dry Remnant Bone is not without the power to fight.

Chen Xun didn't want to make progress, he actually wanted to dismantle these Star Iron Demon Bodies, how could Chang Zhen not vomit blood in anger?

Chen Xun's mind was very simple, the opening of the fourth floor of the Xuyuan Hall was controlled by the main hall's own prohibition, and Chang Zhen and Lao Kui could not open it.

Chen Xun didn't expect to be able to pass the trials of the fourth-layer hall before cultivating the Yuan Shen Law Phase, but to resist the hundreds of millions of monsters that would come at any time in ten years, he could dismantle hundreds of formations comparable to earth-level magic weapons from the Star Iron Demon Body......

Canglan has hundreds of earth-level magic weapons at once, which will not make people suspect anything, at most, he thinks that when the Shenxiao Sect is broken, some of the sect's treasury will be asked to be brought out.

Chen Xun estimated that he could pick up sixteen pieces of Xuanyan Spirit Armor, but only by cooperating with the Xuanyan Battle Array of twelve people could the Xuanyan Spirit Armor exert the power comparable to that of a heaven-level defensive magic weapon, and when worn alone, it could only provide the defensive power of a ground-level magic weapon.

Chen Xun just wanted to pick out Su Junyuan and the other twelve people, and the Xuanyan battle array formed by them would not weaken the attack power of Yuan Dan Wuxiu and the defense power of the Faxiang Zhenren.

Su Junyuan refined the true blood of the Destiny Yuan into the Soul Lock Seal, so naturally there was nothing to trust, so Chen Xun frankly told him some things about cultivating the second Yuan God and incarnating outside the body to dispel his doubts......
