The disciples of the four sects retreated to the Tianzhu Peak in the north to rest and prepare for the fierce battle that followed.

After the demons captured the old dragon pool, unexpectedly, they spent two days in the old dragon pool, not only did they concentrate their forces to fight back wildly in the Thousand Demon Sand Sea, but they went south from the old dragon pool, went east out of Tu Mountain through the Canglan Rift Valley, and then went straight to Yuanwu County through the Wuteng Sand Sea.

After the destruction of Yuanwu County City, the defense of many remaining cities was overwhelmed, and the six Rakshasa demon generals joined forces to strike. Millions of demons swept through like swarms of locusts, and it could be said that there was no grass along the road.

The monks of the small and medium-sized sects, if their hands and feet are a little slower, will also be ruthlessly devoured by the demons.

The demon clan only borrowed the road in Yuanwu County, and turned to the northeast from the Wuteng Shahai Sea, swept over Mengshan Mountain like locusts, crossed Gushan, and went straight to the northern wasteland......

There was only one wreck left on the side of the old dragon pool.

The ten Fazhen Realm powerhouses, more than 100 Yuan Dan Realm powerhouses, more than 500 Tianyuan Realm powerhouses, and more than 40,000 Rebirth Realm monks who died in Laolongtan, the disciples of the Northwest Regions accounted for sixty percent.

The Shenxiao Sect was shattered, and the old Longtan was defeated, and the power of the Northwest Domain Sect could be said to have suffered a catastrophe.

The Yuanwu Marquis Mansion has always known the way to protect one's self, and after the destruction of the Shenxiao Sect, its power expanded dramatically, and the monks under its command and affiliated sects were once as high as more than 4,000 monks.

In order to grasp the dominance of the Metropolitan Protectorate, Jiang Wei incorporated the Yuanwu Marquis Mansion and the three thousand elites of the affiliated sects into the Metropolitan Protectorate, and in the end, less than 300 people survived.

After Jiang Bin lost the Kuilong Battle Banner, the three hundred black-armored generals under his direct command were less than fifty after the war.

Jiang Bin did not stay in the Thousand Demon Sand Sea for a long time, and after the main force of the Demon Clan withdrew from the Old Dragon Pond, he led the remaining black-armored generals to leave gloomily and returned to the South Ridge of Tu Mountain.

As for the various things that happened during the bloody battle in the Thousand Demon Sand Sea, no one mentioned it again.

Before the war, the Four Sects and the Canglan Marquis Mansion had a total of more than 2,000 rebirth realm monks, and after the war, there were less than 1,000 left.

There are many sects in the northwest region, only one or two strong people in the Yuan Dan Realm are supported, and after the strong epidemic in this battle, even if the sect is completely defeated, many of them are the outer forces of the Yuanshen Xiao Sect, and at this time, they intend to directly attach to the four sects and the Canglan Marquis Mansion......

By the time Tao Jinghong entered the Northwest Territory with the second batch of reinforcements from Ce Tianfu, the Demon Clan had already been far away from the Northern Wilderness Absolute Domain, fifty or sixty thousand miles away, and stopped in a Peerless Domain called Heiyin Ridge.

Heiyin Ridge itself belongs to the extremely cold and gloomy land, it was the lair of the Thousand Demon Sect four thousand years ago, and it was also the ancient battlefield of the former Ji clan to exterminate the Thousand Demon Sect.

The elite of the Ji clan and the disciples of the Thousand Demon Sect of the former dynasty, there were hundreds of thousands of people buried in the Black Yin Mountains, and countless living souls and dead souls could not be transferred to reincarnation, and they drifted in the Black Yin Mountains all day long.

Heiyin Ridge has long been derived from the Xuanyin Absolute Evil Land, thousands of vertical and horizontal mountains and valleys, breeding a large number of poisonous mist and evil miasma, devouring souls, people and beasts are killed immediately, and even breeding a large number of ghosts, it is the most well-known forbidden land in the Northern Regions.

After the demon clan captured the old dragon pool, a large number of monks and disciples who failed to break through became the great tonic pill of the demon clan. The demon clan followed up from Yuanwu County to the north, and many signs confirmed that the demon marshal Chihuo Ming and many heavenly demon-level demon generals under his command were very likely to have recovered their cultivation.

And the Xuanyin Absolute Evil that pervades the Black Yin Ridge all day long can replace the Demon Evil, so that the Demon Race can survive in Yunzhou.

A month later, Chen Xun, Chang Xi, Zhao Chengen, Gu Chengzhuo and others led more than 100 monks and four Xuan chariots to gather at Zhouwu Mountain by floating boat.

Zhouwu Mountain is thousands of miles long, and it is separated from Heiyin Ridge by a desert that is seven or eight thousand miles wide.

There are a lot of spiritual vein resources in Zhouwu Mountain, but it is a cold place, with three or forty thousand miles of sparsely populated around, and there are not many wild beasts in the mountain, but they are extremely strong.

Practice, people and people are wealthy.

Zhou Wushan only has spiritual vein resources, and there is no large population around him to provide a large number of highly qualified disciples, and there is no secular society to provide enough tribute, so it is naturally far from being able to support a powerful sect to gain a foothold here.

Previously, there were many scattered cultivators and more than a dozen small and medium-sized sects in Zhou Wushan, but under the sweep of millions of demon clans, they were all scattered and scattered, and only two or three hundred monks did not even have a place to stay.

At this moment, Zhou Wushan gathered tens of thousands of monks, facing Heiyin Ridge from afar.

The demon clan attacked the old dragon pool, although it also paid a very heavy price, but at this time, the low-level demons who retreated to the Black Yin Ridge Absolute Evil Land would not be less than two million, among which the small demons who had cultivated into the primordial gods would not be less than a thousand, and there were about fifty heavenly demon-level demons whose strength was comparable to that of the powerhouses of the Law Phase Realm......

If the Ce Tianfu was not fully prepared, with the seven Heavenly and Human Realm True Monarchs and more than sixty Law Phase Realm True Monarchs gathered in Zhou Wu Mountain at this time, the chances of capturing the Black Yin Ridge would not be higher than thirty percent.

Zhou Wushan is full of powerhouses in the Heavenly and Human Realms and the Law Realm, not to mention Chen Xun, even Chang Xi and Zhao Chengen have become insignificant small characters.

It was only at the edict of Tianfu that Chen Xun and the others were inconvenient to leave without permission, so they could only find a valley at the western foot of Zhouwu Mountain and lead everyone to temporarily station.

One day, Chu Yuezhen of the Xuandu Sect rushed to the Xilu Valley to see Chen Xun.

The Thousand Demon Sand Sea fought side by side in a bloody battle, Chu Yue Zhenren came to visit the door, Chen Xunzi was very enthusiastic, and invited him to sit down in the animal skin tent and drink tea.

"Heiyin Ridge is a place of Xuanyin Absolute Evil, the ghosts and things in the territory are vertical and horizontal, the demon clan retreats into Heiyin Ridge, like a fish in water, the monks of all sects want to attack Heiyin Ridge, the casualties must be extremely heavy, I think that the Heavenly Mansion and the sects may not be able to have this determination. Chu Yue Zhenren said.

A wry smile appeared at the corner of Chen Xun's mouth, Ce Tianfu really had to be decisive, he should have gathered so many powerhouses in the Heavenly and Human Realms and the Law Realm a year ago to solve the troubles at the Demon Ruins Mouth in one fell swoop, and the shape would not have been dragged like this.

However, hundreds of thousands of miles away from Yunzhou, the powerhouses of the Heavenly and Human Realms are mainly concentrated in the Six Sects, the fire has not yet burned the eyebrows of the Six Sects, and there is no great temptation of interests, who of the Six Sects is willing to alarm the powerhouses of the Heavenly and Human Realms who have been cultivating for many years, and venture to the Northwest Regions to kill the monsters?

Now it's burning eyebrows, but if you want to storm the Black Yin Ridge, you have to be prepared to sacrifice two or three Heavenly and Human Realm powerhouses.

Don't say that these Heavenly and Human Realm powerhouses themselves are god-like beings who stand above all living beings, and they may not have the idea of protecting the common people in their hearts, but for the Six Sects, the fall of any Heavenly and Human Realm powerhouse is a fatal loss, and it may lead to the collapse of the entire sect, and there may not be anyone willing to take the risk of fighting.

After the Taishang Elder of the Xuandu Sect, Ku'an Zhenjun, returned to Xuandu Mountain for meditation, the other two Heavenly and Human Realm True Monarchs of the Xuandu Sect and the Yangkun Zhenren of the Xuandu Sect were all ordered by the Heavenly Mansion Fu and rushed to Zhou Wushan at this time.

The Xuandu Sect gathered so many strong people in Zhou Wushan, obviously not wanting to capture the Black Yin Ridge and kill the demon clan regardless of casualties.

From the meaning revealed by Chu Yuezhen, Chen Xun could also guess that the meaning of Cetianfu and the Sects was most likely to use the Xuandu Sect as the core, build a defense line in Zhouwu Mountain, and block the millions of demons in the Black Yin Ridge as much as possible.

The Xuandu Sect is the first sect in the Northern Regions, and from Zhou Wushan to the southeast is the sphere of influence of the Xuandu Sect, and after the crippled Northwest Regions, only the Xuandu Sect in the Northern Regions has the strength to transfer one or two Heavenly and Human Realm True Monarchs to sit in Zhou Wushan.

Chen Xun asked Chu Yue Zhenren: "Has Ce Tianfu considered why the demon clan chose to retreat to the Black Yin Ridge? The battles of the Thousand Demon Sand Sea and the Old Dragon Pond, many signs show that the demon clan's plan is quite thorough, but Yunzhou is ......passive everywhere."

"There are many possibilities that Cetianfu has considered. Heiyin Ridge was originally the mountain gate of the Thousand Demon Sect, and after the Ji clan captured Heiyin Ridge, it quickly declined and was replaced by Emperor Xiwu. After hundreds of years of chaos, the order was re-established. When everyone has time to turn their eyes to the Black Yin Ridge, the Black Yin Ridge has been filled with poisonous mist and miasma, breeding strong ghosts. There may be a secret cave of the Thousand Demon Sect that has not been discovered by the Ji clan in the Black Yin Ridge, and the spatial rift that was sealed by the Ji clan four thousand years ago is in the depths of the Black Yin Ridge, and the demon clan retreated to the Black Yin Ridge, perhaps to break this seal and open a second passage to the Thousand Demon Realm in Yunzhou......"

Chen Xun nodded, thinking that below Jiang Mingtai, the master of the Heavenly Mansion, and many powerhouses of the Six Sects, none of them did not schemate, so he really didn't have to worry about the Heavenly Mansion Venerables would not be able to guess the intentions of the Demon Clan.

At this time, it seems that the second possibility is extremely high, but it is not easy for the demon clan to lift the seal of the Heaven and Earth Circle laid by the Ji clan back then.

Even if the demon clan can lift the seal of the Heaven and Earth Circle laid by the Ji clan back then, if they want to form a stable spatial channel in this spatial rift, it will not be easy to re-arrange the Heaven and Earth Circle of different natures.

Cetianfu hopes that the Xuandu Sect will establish a defensive line in Zhou Wushan, hold it for a long time, and consume the demon clan to a little bit of Cheng Dù, and then carry out a strong attack, which is a safe expedient measure.

Gu Chengzhuo borrowed his waist and said, "In this way, we can go back immediately......

Seeing that Chu Yuezhen wanted to speak and stopped, Chen Xun asked, "Senior Chu Yue, what else do you have to say to Chen Xun?"

"In the battle of the Thousand Demon Sand Sea, the Xuanlei Chariot and the Mountain and River Chariot were all mighty, and the imprints left on everyone were extremely profound. The Xuandu Sect wants to change the refining method, I don't know what is urgently needed by the Kui Long Pavilion?" Chu Yue Zhenren asked.

"The Protectorate of the Northwest Regions has cracked the refining method of the Spirit Gathering Forbidden, and the mountain and river chariot that can be refined completely, how can the Xuandu Sect be willing to seek the near and far?" Chen Xun asked curiously.

Although several refining masters in the Northwest Domain Protectorate were not spared, Jiang Zhen, the Marquis of Yuanwu, was himself a refining master, and he would definitely master all the refining methods of the Eight Pillars Mountains and Rivers Chariot.

At this time, Cetianfu counted on the Xuandu Sect to establish a defense line in Zhouwu Mountain, as long as the Xuandu Sect made a request, Cetianfu would hand over the entire set of the Eight Pillars Mountains and Rivers Chariot Refining Method, Chen Xun couldn't imagine why the Xuandu Sect would have to go near and far, and take things to Kuilong Pavilion to exchange the chariot refining method?

"Before the Ku'an Patriarch returned to the sect to retreat, he also said that he hoped to cooperate with Kui Long Pavilion," Chu Yue Zhenren said, "In addition, when the old Dragon Pond fell, including my Xuandu Sect, there were more than a dozen refiners who were not spared, and in the years to come, Kui Long Pavilion may need to help refine a batch of magic array chariots......

Laolongtan failed miserably, and the losses in all aspects were huge.

Jiang Wei, the Marquis of Yuanwu, wanted to monopolize the north and south ridges of Tushan Mountain, and moved the only heaven and earth magic array in the northwest region to the old Longtan for deployment, so he wanted to make the old Longtan the core of the Yuanwuhou Mansion......

After rising and falling, Kui Long Pavilion became the first sect of refining weapons in the Northwest Regions, although it could not even refine a magic weapon above the ground level.

Chen Xun plans to focus on refining the Xuanlei Chariot and the Blue Flame Lotus Arrow in the future in the Dragon Pavilion, and other magic weapons and magic circles can be exchanged with other sects with the Xuanlei Chariot.

In this way, Kui Long Pavilion would be able to refine eight to ten Xuanlei chariots a year at this time.

Although this speed is still far less than when the capital was at its peak, it is also extremely impressive.

The Xuandu Sect, like other sects, had a small number of disciples and elders above the Tianyuan Realm, adding up to less than four hundred, and losing one person was an irreparable loss, but there were more than 20,000 disciples in the Rebirth Realm.

If there were enough mountain and river chariots and Xuanlei chariots, this would actually mean that the total combat power above the Xuandu Sect Tianyuan Realm would increase by five or six times......

In the battle of the Thousand Demon Sand Sea, if the disciples of the four sects did not have forty Xuanlei chariots to cover their flanks, it would be extremely difficult to connect to the close evil array without using the Blue Flame Lotus Arrow.

The Xuandu Sect's request for cooperation, Chen Xun naturally agreed, Chu Yue Zhenren gathered six secret seals similar to the soul lock seal from the storage bag, handed them to Chen Xun, and said: "You practice puppet techniques, these six demon generals may be of great use to you, even if it is a deposit paid by my Xuandu Sect!"

The six secret seals are trapped, four are the little demon generals, and two are the gods.

The Thousand Demon Sand Sea captured the evil formation, and the disciples of the four sects obtained a total of eleven little demon generals, all of which were concentrated in Chen Xun's hands, but Chen Xun did not catch any of the heavenly demon-level demon generals.

Seeing that Chu Yue Zhenren actually took out two Heavenly Demon-level Demon General's Yuan Shen, Chen Xun knew that it must be Ku'an Zhenjun's capture in the Old Dragon Pond, so he didn't shirk it at the moment, and happily accepted it.
