Chen Xun's thoughts suddenly became clear. He suddenly opened his eyes, put his fingers on the pen, gathered the spirits into ink, quickly dotted the virtual painting, and drew a new spirit-gathering prohibition in the void...

"Oh, have you deduced the new ban?" Old Kui crawled out of the Void Yuan Pearl, looking at the spirit gathering ban formed in the void, slowly sucking the spiritual energy in the cliff cave, and also knew that Chen Xun had achieved success at this moment.

"The Jiang family has indeed made outstanding achievements in laying the foundation of the mountain and river magic circle! From four pillars to eight pillars, it seems to have a limited span, but the mysterious formation ban is abnormal, and the complexity has increased by more than ten times. It took a year more than I expected to deduce all the mysterious ones."

Chen Xun looked at the cave wall to make it easier to calculate the number of days, and there were as many stone marks as many as 1,000. Unexpectedly, he had been in seclusion in Nanling just to deduce the new spirit gathering ban.

In the past three years, he not only deduced the new spirit-gathering ban, but also deduced the changes in the mountain and river defense magic array from four pillars to eight pillars.

As the general outline of the Changzhen clan's weapon refining, Xuanyan Jue is really powerful enough.

If it weren't for the second level of magic, almost all the defensive-level magic arrays and ground-level magic weapons were refined thoroughly. Chen Xun would not have deduced the changes in the mountain and river defense magic array in such a short time.

The deductions he made were only to verify the mysterious and profound refining principles of the Xuanyan Art through his understanding of the changes in the defense method of mountains and rivers.

It is quite a matter of knowing mathematical axioms and theorems, and then performing practical application solutions.

In time, he will be able to deduce the basic formation of the mountain and river defense magic array. Knowing the basic formation of the mountain and river defense magic array, he will master the foundation of the Shanhe series of magic arrays, and deduce the soul-suppressing and locking dragon-locking mountains and rivers heaven and earth magic array. It is only time.

This time may be hundreds of years, but with Chen Xun's further understanding of the Xuanyan Art, it should be ultimately deduced.

If it were other grandmaster-level weapon refiners, perhaps thirty or three hundred years might not be able to deduce the changes in the defense of mountains and rivers from four pillars to eight pillars out of thin air, let alone deduce the basic formation.

No wonder countless monks with great talent are unwilling to waste their time on refining weapons, which is really too delaying in their practice.

Fortunately, Chen Xun used the Xuanyan Art to deduce the formation prohibition, and his spiritual consciousness was also enhanced.

When deducing the formation prohibition, Chen Xun also had a deepening understanding of the magical powers that can evolve into the formation prohibition, as well as the deeper and more mysterious Taoist meaning behind it.

The formation restrictions and various magical powers are ultimately just a interpretation of a certain way of heavenly aggregates.

Chen Xun refines Xuanyuan Holy Blood and refines Xuanyuan Holy Body. He needs to understand 365 Taoist meanings and create 365 Yuan Dans to achieve perfect Yuan Dan.

This actually requires him to have much more profound understanding of the way of heavenly aggregate than others, so that his cultivation level can be further improved.

The fundamental Taoist system of Xuyuan Palace, the Xuanyuan Bible and Xuanyan Art complement each other, is not unreasonable.

Without using the Xuanyan Art to comprehend and hone various Taoist meanings, the Xuanyuan Bible will not be able to achieve great success.

***************************

At this moment, there was a noise outside. A talisman came in, but Luo Yuze, who had been waiting outside the cliff cave for many years, sensed the noise in the cliff cave:

"Marquis Canglan, have you understood the prohibition on gathering spirits?"

Under various restrictions, the outside can only send sounds through spiritual talismans.

Lao Kui turned into a wisp of blue smoke and drilled into the Void Yuan bead.

Chen Xun swallowed the Pearl of Void into his belly and hid in the depths of the Spirit Sea before he lifted the ban in the caving cave. Seeing Luo Yuze, Yuanwu Hou Jiang Xu and both stood outside the caving cave.

Chen Xun pointed to the spirit gathering prohibition condensed by spiritual energy in the cliff cave and said to Jiang Xu: "Please inspect the goods by Yuanwuhou!"

Jiang Xu is also a master-level weapon refiner. He can see at a glance whether the new spirit gathering ban can match the Eight Pillars Mountain and River Warriors.

However, the more he understood, the more shocked he was:

With his practice of refining weapons for thousands of years, even if he mastered the basic formation of the spirit-gathering ban, he would not be able to achieve it in three years if he wanted to deduce the new spirit-gathering ban.

Although this boy's cultivation is not high, his understanding of weapon refining can be described as a genius. Or is the inheritance he obtained from Yuzhu Peak far exceeding others' imagination?

Chen Xun waved his sleeves and turned the spirit gathering ban formed by spiritual energy into a ball of shattered spiritual light, scattering invisible in the dim cliff cave, saying, "The Protectorate can pay a deposit of 50% at this time. Within six years, Wushan will successively refine 200 sets of spirit gathering bans and send it..."

The simple spirit-gathering prohibition is only equivalent to the top level magic weapon. It is naturally not a problem for Kuilong Pavilion to refine 200 level magic weapons in six years.

A ray of streaming clouds came from the sky in the north. Tao Jinghong sensed that Chen Xun had left the pass and was rushing back to Yuanwu New City from Nanling.

Jiang Ju looked gloomy and nodded, "Okay. Five thousand armor-breaking heavy-edge spears, fifty thousand pieces of Vajra Black Armor, and five sets of thirty-two pillars of mountain and river formations. They are already ready, and are waiting for you to come out of seclusion and take them away..."

Luo Yuze was also secretly frightened. He didn't expect that the Northwest Region Protectorate would really pay such a high price for the 200 sets of spirit gathering prohibitions that are only equivalent to the top-level magic weapon.

The Thirty-Two Column Mountain and River Magic Formation is not very strong, but even the lowest level of forbidden magic array is comparable to a thousand top-level magic weapons.

Ten mountain and river ban arrays, 100,000 armor-breaking heavy-edge spears, and 100,000 pieces of Vajra Black Armor were exchanged for 200 sets of spirit gathering restrictions. Thinking about it, I can't even lose my underwear.

But thinking about how to ride two hundred mountain and river chariots into the Demon Ruins in the future, the Protectorate could only grit his teeth and endure it at this time.

Luo Yuze didn't understand why Uncle Shi was so indulging in Wushan, ten mountains and rivers sealed magic circles, ten thousand armor-breaking heavy-edge spears, ten thousand Vajra Xuan armor, and Wushan gathered 100,000 barbarian martial arts. Isn't this an optional force?

Chen Xun bowed to Tao Jinghong and said, "I finally don't let down the expectations of Tao Zhenjun. I will go back to Wushan to refine two hundred spirit-gathering bans for the Protectorate's Mansion. At that time, the chariots traverse Tushan, kill monsters, and protect the people..."

"In this way, I will also settle down my mind." Tao Jinghong stood above the clouds and said to Luo Yuze, "Yuze, you stay in the northwest region, and you must obey the orders of the Protectorate's Palace in everything!"

Tao Jinghong stayed in the Northwest Region for several years in order to kill demons. At this time, the Northwest Region Protectorate was on the right track, and the touch of Haoran's Heavenly Dao, he also wanted to return to Longmen Sect and comprehend it well.

******************************

Wushan soldiers and horses winding between the steep valleys, like long dragons, with the roof of the Xuanthunder chariot covered with thunder clouds. Even if they stood on the top of the mountain dozens of miles away, Jiang Bin could still sense the thunder breath revealed in the dark clouds.

"Master Tu has cracked the spirit gathering ban of the Four Pillar Mountain and River Formation, and you have seen the new spirit gathering ban, Father. With Master Tu's power, I think it will be cracked in less than two years," Jiang Bin asked in confusion, "I really want them to take away so many soldiers?"

They hurriedly gave up Yuanwu County City, and the losses were also heavy. At this time, they used five mountain and river ban arrays and 50,000 Xuan soldiers and heavy armor to go out, which was almost one-third of their treasures.

"Let them take away these armor and magic circles. If Chen Xun had any accidents, others would not doubt our heads." Jiang Xu restrained the divine light like lightning in his eyes.

"Tao Jinghong will always be suspicious." Jiang Bin said.

"What can Tao Jinghong be suspicious?" Jiang Xu smiled, "He is so enthusiastic about the affairs of the Northwest Region, and Tianhe and other sects have already made some remarks. He said that it was because he had the opportunity in the Northwest Region that year and needed to repay him, but how could Cetian Prefecture and the other five sects believe his words? As long as he can't get the evidence, what can we do?"

"Chen Xun stayed in Yuanwu New City and deduced the new spirit gathering ban. The inheritance of Yuzhufeng is likely to be in his mind," Jiang Bin asked, "Do we even want the inheritance of Yuzhufeng?"

"This is a pity, but the timing cannot be delayed. Once Wushan's wings are full and they will be difficult to cut them off," said Jiang Xu. "You should concentrate on comprehending and practicing the battle formation of mountains and rivers. We abandoned Yuanwu County City. Although we have preserved our strength, our reputation has fallen to a deep valley. If you cannot regain the reputation of Yuanwu Hou Mansion, how many strong people will follow you to the Tianjun Secret Realm in twenty years? The inheritance in Tianjun Secret Realm is definitely not comparable to Yuzhu Peak."

*********************************

Longque Ridge. The mountain is like a sparrow's tongue. The wind is strong and the plants and trees do not grow. Those with a slightly lower cultivation level cannot gain a foothold on the top of the mountain.

Four years ago, the range of the Flame Sea vortex has shrunk to a radius of 600 miles.

Longque Ridge was previously located at the edge of the vortex of the Flame Sea, but at this time, the area of ​​Longque Ridge was more than 200 miles eastward, and it was completely exposed to the edge of the Flame Sea. It was a sea of ​​sand that was full of grass without any grass growing.

These areas were originally steep and steep.

The demon dragon tore the void, forcibly penetrated into Yunzhou, refined the sky flame, and the Qingluan sacrificed her body, and used the final level magical powers of the Glazed Flame Sea. The mountains that were nearly a radius of thousands of miles were torn and smashed.

The indestructible rocks have now turned into fine sand all over the valley, and the wind blows, flowing like waves.

Everyone guessed that the area covered by the Sea of ​​Flame at this time also turned into a sea of ​​sand.

Everyone calls this area in front of them the Thousand Demons Sea, surrounded by the majestic mountains around them, and it looks like a Thousand Demons City.

After dispatching defense, Chen Xun went into seclusion in Nanling to deduce a new spirit gathering ban, but Wushan's movements did not stop. In three years, a city was built in the valley on the southern foot of Longqueling, based on a piece of undestroyed spiritual vein, and stockpiled military armor and supplies.

At this time, a mountain and river ban array was placed in the city, completely sealing the valley thirty or forty miles on both sides.

Going back is the steep mountains and ridges of Tushanxi Ridge. Going forward to the Thousand Demons Sand Sea, where spiritual veins are connected, it is the only place with a few important places that can block the Thousand Demons Sand Sea in a radius of thousands of miles.

Ordinary cultivators who return the body will find it extremely difficult to fly in the air and exceed one thousand feet of height.

The monsters that will pour into Yunzhou this time will mainly include hundreds of millions of low-level monsters, and choose dangerous and narrow key areas between the mountains and ridges to build a strong city and lay a magic circle, which is still of great significance.

Chen Xun stood on the top of Longque Ridge, looking at the sea of ​​flames two hundred miles away, and remembered the scene where the light of Qingluan shone through his body.

Although the sea of ​​flames condensed into the sky flames of Tushan, it is more fierce than the sky flames of Tushan.

In the past, the cultivators in Tianyuan Realm could barely do anything close to the range of two or three thousand feet in Tushan. At this time, Chen Xun was close to the range of ten thousand feet in the sea of ​​flames, and the spiritual energy in his body surged like a boiling fire, which was difficult to control.

At this time, several people came from the air, more than a hundred feet apart, and said loudly: "General Fu Yan asked Cang Lan Hou to observe the changes in the flame sea..."
