Chen Xun sat cross-legged and meditated, and when he was cultivating the Nine Qi Yang Refining Technique, an extremely agile Kui Long Phantom hovered behind him.

In the dungeon of the secret room, the rich aura is turning into more than a hundred wisps of wisps of cloud-like qi, which is directly merging into his body through the hundreds of spiritual apertures, and is continuously injected into the Xuanbing Fire Lake transformed by the spiritual sea through the spiritual veins.

Chen Xun opened his eyes and saw that a small half of the incense burned by the incense burner had not been burned, and he was also shocked in his heart.

In the late stage of advancing to the rebirth realm, the refining spirit veins reached the twelfth extreme, and the number of hundred spirit knots opened up also reached more than one hundred and twenty, but at the same time, the Xuanbing Fire Lake transformed by the spiritual sea also expanded nearly doubled, Chen Xun originally thought that the time for him to refine the spiritual energy of heaven and earth would be extended, but he did not expect that it would be shortened by half.

This actually meant that his efficiency in refining the aura of heaven and earth was four times higher than before.

Ordinary rebirth realm cultivators, every time they refine and open up a spiritual vein, the improvement of qi refining efficiency is quite limited, only when they reach the number of nine or twelve poles and open up more than 100 spiritual apertures, the qi refining efficiency will soar sharply.

At this time, whether it was the speed of refining the spiritual energy of heaven and earth, or the majesty of the spiritual energy in his body, Chen Xun was actually not much worse than the early stage monks of the Tianyuan Realm, far from being comparable to ordinary late-stage monks of the Rebirth Realm.

Chen Xun refined the Divine Soul Life Yuan contained in the two Essence Battle Souls, and completely consolidated the cultivation realm in the late stage of the Rebirth Realm, before pushing open the iron door of the dungeon and officially exiting the customs.

In the secret room outside the dungeon, he often actually sat in front of a huge stone platform to deduce the formation.

Chen Xun secretly wondered that the aura revealed by the secret room and dungeon was extremely stable, which meant that when he was in retreat and cultivating for more than half a month, Chang Zhen had already set up a new forbidden formation in Longyun Pond, why did he sit in front of the stone platform and deduce the formation.

Chang Zhen's mind and soul were immersed in the deduction of the formation, and Chen Xun walked out of the dungeon inside without realizing it; Chen Xun could feel that the breath exuded by Chang Zhen was even more old and weak, and he took several pieces of red essence copper plates from the stone platform to deduce the formation, and the engraved patterns on them were all similar to the Gathering Spirit Prohibition, but it was not completed yet, but it was doubly complicated.

Chang Zhen, the old monster, is actually deducing newer and more complex spirit gathering prohibitions.

In the secret room, except for Jiang Bingyun, who was in retreat and cultivating, Lao Kui was nowhere to be seen.

The star-iron demon body was still standing there straight, and Lao Kui was nowhere to be seen, referring to the fact that he didn't know where his primordial spirit had gone.

At this time, Zuo Aoki walked down from the secret pass, Chen Xun saw that he was exhausted, and knew that during the period of his retreat and cultivation, the monsters gathered north of the Python Ridge would not stop disturbing the Dragon Pool, and the scale of the gathering would become more and more, and the pressure on the hearts of the people trapped in the Dragon Pool was extremely great.

And Zuo Qingmu has to assist Chang Zhen in repairing and laying out a new magic circle during this time, and the consumption must be very large, Chen Xun asked: "What about the old kui others?"

"When Mr. Chang set up the forbidden magic circle, there was a faint vibration from the depths of the spiritual veins, and it has been ten days since Mr. Kui sneaked in to see what was going on......," Zuo Aoki said.

The Void Yuan Secret Hall was hidden in a spiritual cave nearly twenty miles deep under the cold pool.

Longchuan Pond is one of the main spiritual veins of Python Tooth Ridge, and the extreme depth does not know how many times more complicated than the Hantan Crypt. If there is an abnormality in the extreme depths of the spiritual vein, or if there is a fierce beast lurking in the extreme depths of the spiritual vein, it will definitely be a catastrophe for the house leak to coincide with a downpour.

"There is a turtle in the depths of the spiritual vein," Chang Zhen put down the red essence copper plate in his hand, and saw that Chen Xun and Zuo Qingmu had worries on their faces, and said, "When Lao Kui sealed this spiritual vein, this turtle was not the size of a tail finger, so he inadvertently let it drill into the depths of the spiritual vein. Suddenly ten thousand years have passed, and no one would have thought that this Xuan Turtle would have been dormant in the depths of the spiritual veins for so long. When I was setting up the Xuanyin Heavy Water Array, this Xuangui actually attacked the eye of the formation, and I couldn't use Lao Kui to dive down the spiritual vein, so why did I have to subdue this demon first......"

Chen Xun didn't know how deep Lao Kui's Yuan Shen had infiltrated the spiritual vein, he couldn't sense Lao Kui's existence, and he was worried that Lao Kui was weakened at this time, and he might not be able to subdue the Xuan Turtle who had lived in the extreme depths of the spiritual vein and cultivated for ten thousand years.

"This turtle has been dormant in the depths of the spiritual vein for nearly 10,000 years, although the Yuan Dan will be cultivated to perfection, but the spiritual intelligence is extremely weak, and he has not cultivated any magical powers, except for a strong armor and old skin comparable to the secret iron of the stars and infinite strength, there is not much threat," Chang Zhen and Kui Long's Yuan Shen, separated by thousands of miles, can communicate through the divine thoughts, and naturally knows the situation in the extreme depths of the spiritual vein, "You throw the Soul Breaking Bead and a Soul Lock Seal down, Lao Kui is going to destroy this Xuan Turtle......"

Chen Xun handed over the Soul Breaking Bead and Soul Lock Seal to Chang Zhen, although the spiritual vein had only one opening in Longshu Pond, it branched out a lot to the depths.

He couldn't sense Lao Kui's storage, and the soul breaking beads and soul lock seals could only be handed over to Lao Kui by Chang Zhen.

The Xuan Tortoise has never been in contact with humans and beasts since he was dormant in the spiritual veins of cultivation, and his spiritual intelligence must be extremely weak, and he has not yet cultivated his supernatural powers, and his strength will not be exaggerated.

Just like Chen Xun, he cultivated and opened up twelve spiritual veins, and advanced to the late stage of the rebirth realm, the cultivation realm is already quite not weak, but if there is no thunder sound sword technique, Kui Long Spirit Armor, demon body puppet, Yunchen Armor, Thunder Fall Sword, Blue Flame Lotus Arrow, Gathering Spirit Mountain River Array and many other magic powers, magic weapon treasures, strength, strength may not be much stronger than the disciples of the True Yang Realm.

However, the Xuan Tortoise no longer has supernatural powers, no matter how weak his spiritual intelligence is, he has been dormant and cultivating in the depths of the spiritual veins for ten thousand years, and the strength of the demon body and the infinite divine power still make Chen Xun worry about whether Lao Kui still has the strength to subdue this Xuan Tortoise at this time.

No matter how worried he was, he couldn't help, Chang Zhen was in charge of the secret room, and Chen Xun didn't bother him to keep in touch with Lao Kui at any time.

I didn't think that there were monsters surrounding the mountain outside Longshu Pond, not to mention, at this time, there was still a spiritual vein turtle internal trouble, he only had bitterness in his heart, but he didn't have time to stay in the secret room to indulge in worry, so he walked out of the secret room at the bottom of the pool with Zuo Aoki first.

Walking out of the secret room, Chen Xun saw a water curtain-like shield shrouded in the sky above Longqi Peak, and countless mystical talisman secret seals flickered on the water curtain, as if clouds were circulating.

A defensive circle that can completely enclose a river and a mountain, also known as a forbidden circle.

The Xuanyin Heavy Water Array is a mountain range that can cover the surrounding mountains and ranges for nearly twenty miles, ensuring that the spiritual energy gushing out of the spiritual veins does not overflow, but the wider the area covered by the magic array, the weaker the defense.

At this time, the Xuanyin Heavy Water Array only covered a limited area such as Longshu Pond and Longchuan Peak, ensuring that two hundred monsters and monsters rushed up together, and none of them could tear apart the sealing shield.

In the forbidden array, the aura was unprecedentedly full, but seeing the faint figure of the monster on the mountain in the distance, Chen Xun frowned deeply, and asked Tie Xintong, who came over: "How many monsters have gathered in Beishan at this time?"

"Nearly a thousand," Tie Xintong said, "Elder Su, they are all ...... on the mountain."

They are not passive defenses.

Blindly passive defense, no matter how strong the mountain defense array will be, it will be breached.

The Xuanyin Heavy Water Array can resist the simultaneous attack of one or two hundred monsters, but thousands of monsters are swarming up from all directions, can the Xuanyin Heavy Water Array still resist?

Monsters will even explode their own blood pills.

The Blood Pill was inferior to the Yuan Dan, but the power of the Martyrdom Explosion was by no means slightly worse than a salvo of several Blue Flame Lotus Arrows......

Seeing that the monster has signs of self-detonation of the blood pill, people can still avoid it from afar, but how to avoid the monster's blood pill explosion with the ban shield?

Chen Xun and Zuo Aoki flew to the top of Longchuan Peak with Tie Xintong.

Before Su Fanglong and the ten monks of the Canglan Academy rushed to reinforce them, Lao Kui used his supreme divine power to open the stone caves that directly connected to the bottom of the pond on the left and right peaks, ensuring that there could be a majestic aura that could be directly led from the bottom of the pool to the two dragon peaks on the left and right.

And the two four-pillar mountain and river arrays deployed here were all brought by Su Fanglong from the White Wolf River, and controlling the high point of Longyu Pond could ensure that hundreds of monsters could not directly attack the Xuanyin Heavy Water Array without distraction.

In addition, there are also two refined copper chariots deployed into the valley mouth of Longchuan Pond, which can be dispatched at any time to contain the monsters of Beishan and prevent them from entering the White Wolf River on a large scale.

Seeing that Su Qingfeng, who he hadn't seen for many years, was also on Longqiu Peak at this time, Chen Xun was slightly shocked in his heart, and secretly said No wonder Jiang Bingyun was still hiding in the secret room to cultivate at this time, it turned out that he was wearing a mask, and he didn't dare to meet Su Qingfeng.

"The Thirteenth Master hasn't seen you for a long time," Chen Xun walked over to salute Su Qingfeng, "This is a time when Beishan is in danger, the Thirteenth Master and Elder Su have come to the aid of thousands of miles, Chen Xun will never forget the kindness of the Canglan School Palace in the future......

In order to keep Su Tang stationed in the White Wolf River, Su Qingfeng and Su Fanglong rushed over to support Longchuan Pond, knowing that Chen Xun was in retreat and cultivating.

At such a time when his brows were burning, Chen Xun still had the heart to retreat and cultivate, and his strength must be able to make a great breakthrough in a short period of time.

Su Qingfeng saw Chen Xun standing in front of him, his momentum was actually blended with the mountains, if there was nothing, and it was extremely heavy, he was secretly surprised in his heart.

Su Fanglong saw Chen Xun in Mengshan two years ago, and returned to Canglan School Palace to say that Chen Xun had already cultivated in the middle of the fetal realm, and at that time everyone thought that Chen Xun's cultivation progress was so fast, but they didn't expect that in the past two years, Chen Xun broke through again, and with such a cultivation speed, Canglan School Palace can be compared with Su Tang and Wuyang.

And on Su Tang and Wu Yang's body, Canglan Academy Palace didn't know how many cultivation resources to invest.

Over the years, Su Qingfeng has been practicing in retreat, and he has long reached the mid-stage consummation of the rebirth realm.

It's not that he can't refine the new spiritual veins and advance to the late stage of the rebirth realm, but if he can't refine the nine spiritual veins and can't advance to the Tianyuan, what is the point of not breaking through?

Su Qingfeng believed that Chen Xun, as a disciple of the inner sect of the Shenxiao Sect, must be aware of the importance of the spiritual vein, and he was able to break through all the way and directly reach the late stage of the rebirth realm without any scruples, which showed that the spiritual veins he had refined and opened up must be above the nine numbers.

Thinking of this, Su Qingfeng's heart was also in a trance, who would have thought that when he first saw this son in Beishan, it had only been fourteen or fifteen years?

Qianlan and Qing Xuan held their spirit swords and leaped up the mountain behind Longyu Peak, Ah Qing followed behind them, and the two-tailed fire fox was grabbing Ah Qing's big ears and riding on its back......

Seeing Chen Xun out of the pass and Su Qingfeng and Su Fanglong talking on the top of the mountain, Qianlan and Qingxuan came over, their clothes were hidden with bloodstains, and just now they went out with Ah Qing to force away the two monsters that were close to Longyu Pond.

Seeing Chen Xun, Qing Xuan's eyebrows and eyes were filled with a light smile, and she said charmingly, "I thought you would have to get out of the customs in a few more days......

Chen Xun was about to say something to Qing Xuan and Qianlan when a huge vibration suddenly came from the ground, almost making everyone unable to stand on the mountain.

At this time, Su Fanglong and Su Qingfeng were shocked.

They have all experienced the battle of Yuzhu Peak, and they know how big the movement was when Yuzhu Peak collapsed, they don't know what happened at the bottom of Longzhu Pond, and the movement at this time is definitely not much smaller than when Yuzhu Peak collapsed.

Chen Xun didn't care about the horror in his heart, and watched the giant peaks on the top of the mountain smashing hundreds of thousands of catties and millions of catties down the mountain, and his heart jumped to the extreme, there were thousands of mortal relatives living in the valleys on both sides of the Longchuan Pond, and I don't know how many people would die when this boulder smashed indiscriminately.

He didn't think about it, he jumped out, and the sword of Thunderfall and the others flew out of the sword box almost at the same time, and spun towards the hundreds of falling rocks......
