After three days of walking southeast, the army finally reached the periphery of the Falling Dust Mountains.

When he came here, Cheng Ling felt a mixed aura, and Liu Qingyan, Jian Yinghao, Zhang Hu and others behind him all had ugly faces.

Liu Qingyan said: "Cheng Ling, the breath here is so chaotic that even the mood is starting to get irritable!"

Cheng Ling turned his head to look, Evil Wind, Jian Yinghao, Su Yi, Bai Suzhen, Xuan Wuxiang and others all nodded silently, only Yang Hongqiu's face was indifferent.

"Brother Evil Wind is a half-demon body, and Sister Bai is a pure demon clan, even they don't feel comfortable, and it is even more difficult for the rest of the others to gain a foothold here. What the hell is going on, why does this Falling Dust Mountain have such a mixed aura?"

He was in a state of thought, his eyes flashing, but he couldn't find the clues in the mountains.

Jin Sheng stepped forward and said, "Star Lord, this place is indeed not suitable for the survival of living beings, let's leave quickly!"

In just this short time of staying for a stick of incense, he found that the sergeants under his command were all suffering, absorbing the mixed breath into their bodies, constantly impacting their muscles and veins.

Cheng Ling nodded slowly and said, "Jin Sheng, Su Yi, you lead everyone to retreat thirty miles, and the breath there is still stable. ”

After speaking, he turned his head to Yang Hongqiu and said, "Master, you can accompany me in and have a look!"

Yang Hongqiu nodded slightly and said, "Okay!"

She knew that Cheng Ling was not afraid of the aura inside if she dared to enter, not even the yin qi of the netherworld, and she was naturally not afraid of the chaotic mixed aura.

Jin Sheng and Su Yi received the order and led their army to retreat.

Liu Qingyan glanced at Cheng Ling worriedly, and the latter gave her a reassuring look, and then entered the mountain range with Yang Hongqiu.

The mountain range is full of dense towering trees, the fallen leaves on the ground have accumulated a thick layer, as Jin Sheng said that there is no human population for a long time, the natural environment is very good, the only regret is that the breath in the air is very mixed.

Cheng Ling felt it slightly, the immortal aura here accounted for forty percent, the demon qi accounted for forty percent, and only the demon qi was slightly rare, only accounting for two percent.

But these two percent of the demonic qi is deadly! As I said before, the demon race can be regarded as the first race after the opening of the world, and the human race and the demon race are both behind. Many of the exercises of the human race are derived from the demon race.

Therefore, the demonic energy does not have much impact on the human race.

But the demons are different, they are very different from the human race in terms of life form, and they are born from the filthy qi between heaven and earth. These filthy qi are poison to the human race, and they cannot be transformed and refined at all.

In order to make the Falling Dust Mountain Range suitable for the survival of the human race, it is first necessary to find the source of the demonic energy.

Cheng Ling's Golden Pages Technique can contain everything, and no matter what kind of breath it is, it can be refined. Yang Hongqiu is a superb cultivator, and the demonic qi here is too low-end for her, and it can't have any impact.

The master and apprentice marched all the way to the depths of the mountain range, Cheng Ling led the way, and Yang Hongqiu followed behind, as if entering a no-man's land.

Cheng Ling had the experience of being on the Demon Blood Continent back then, and he had a lot of experience in finding the source of demonic energy, and traced it all the way in the direction of demonic energy.

Yang Hongqiu didn't say much, this disciple often had something magical, he didn't ask each other silently, and he didn't express his opinion, to see where the other party took him.

After walking forward like this for more than three hours, he had already penetrated thousands of miles into the mountain range, and Yang Hongqiu felt that the demonic qi in front of him was getting stronger and stronger, and he had to start holding his breath to eliminate the interference of the demonic qi.

Cheng Ling keenly sensed her changes and asked, "Master, can you still hold on?"

Yang Hongqiu said: "It's okay, but your exercises are really admired by the teacher, where did it come from?"

Cheng Ling smiled bitterly and said: "I can't tell you clearly, this kind of exercise can absorb almost any breath, and the disciples don't understand its origin. Looking at the intensity of the demonic qi ahead, it should be close to the source. ”

Yang Hongqiu said: "Don't worry, the master is fine." ”

Cheng Ling was relieved at this time, and continued to walk towards the depths of the mountain range.

After traveling hundreds of miles, the two found that the scenery around them was gradually becoming barren. The trees that used to be dense have become fewer and darker, and the road has become wider and darker, with scattered black stones scattered on both sides.

Cheng Ling casually picked up a fist-sized gravel, looked at it seriously, and said in surprise: "Black Wind Stone, so many Black Wind Stones!"

Yang Hongqiu asked, "What is the Black Wind Stone?"

"Black Wind Stone, as the name suggests, is a kind of ore formed by the long-term erosion of the stone by demonic qi and changing the structure inside it. ”

"This kind of ore is rarely seen in other places, and only exists in places where demonic energy has been shrouded for a long time. It is an excellent material for refining sword weapons, as long as it is incorporated a little bit when refining the weapon, the sharpness and lethality of the long sword can be increased by several percent, and it has a strong restraint effect on yin evil things such as yin spirits!"

Yang Hongqiu nodded and said, "The sword weapon you use should be infused with this material!"

Cheng Ling nodded slightly, and did not explain. The Dragon Feather Sword was fused with the Black Wind Drill, which was much more high-end than the Black Wind Stone, which was conceived by the origin of demonic qi and the pressure of the deep sea over tens of thousands of years.

However, it is better to have a black wind stone than nothing, and the five thousand disciples of the Wuxiang Sword Sect, because of the relationship between Cheng Ling and the Sword Pavilion, more than ninety percent of them practice swordsmanship. If they can all be equipped with sword weapons blessed with black wind stones, their own strength will be greatly enhanced.

Not only that, but with the 10,000 army that followed to Kui Wood Wolf Star, Cheng Ling planned to train them to become the foundation of the revival of the sword path. The 5,000-strong army supported by the White Tiger Star Monarch can also become a powerful boost to the revival of kendo if it is properly trained.

With the increase in its own strength, coupled with the help of the sword array, an army of 10,000 can be used as ten!

The thought flashed through his mind, but he didn't stop at his feet, collecting the Black Wind Stone along the way and continuing to move forward.

Gradually, the two came to a large open space. There was a large crater in the clearing, as if it had been smashed by a meteorite. Standing next to the big pit and looking inside, the outer circle was in the shape of a funnel, extending down into the pitch black, and the rolling demonic energy continued to emerge from the center.

When he arrived here, even Cheng Ling felt that his breath was not smooth, and the demonic qi spewed out too much, accounting for more than eighty percent of the breath in the air.

Yang Hongqiu said: "Cheng Ling, the demonic qi here is too strong, is it the source of the demonic qi, what is in it?"

Cheng Ling's eyes were opened, but unfortunately the demonic aura was too strong to see clearly.

Shooting in a circle in all directions, he said: "This place does seem to be the source of demonic energy, and in order for the army to enter the mountain range, it is necessary to deal with the demonic energy here. Master, let's retreat first, the demonic aura here is too strong, and I want to set up a sealing formation on the periphery. ”

Yang Hongqiu nodded, and the two of them retreated, and it was not until a hundred miles away that Cheng Ling stopped, sat down cross-legged, and began to deduce the sealing formation node.

(This chapter is not finished, please turn the page)

The area of demonic qi in the mountain range is very large, but he believes that as long as the source of demonic qi here is controlled, the concentration of demonic qi on the periphery can be greatly reduced.

For three whole days, he sat motionless on the ground, constantly deducing the direction of the node in his mind. Later, on the fourth day, all the deductions were finally completed and arranged one by one.

The light curtain of the sealing formation slowly gathered, and Yang Hongqiu sensed it seriously, and sure enough, he felt that there was a lot less demonic energy. She said happily: "Cheng Ling, sometimes I wonder, how did you cultivate, not only did you cultivate to reach the Nine Star Land Immortal Realm, but you were also good at so many auxiliary means, if you used all this time to cultivate, I am afraid that you would have already ascended to the Immortal Realm." ”

Cheng Ling said with a smile: "It can't be said that the disciple will not improve so quickly if he doesn't have such auxiliary means, and every drink and peck is heavenly." ”

Yang Hongqiu was silent, and after a while, she said again: "The demonic qi here is indeed much less, but it is still unbearable for those monks you brought, are you sure you choose to settle here?"

"It's okay, with my current formation level, I can only seal it temporarily, but I believe that one day I will be able to find a way to channel these demonic qi to other places. Besides, the current demonic energy is much less, and there is no follow-up supplement, as long as it will slowly dissipate after a while. ”

"How long will it take?"

"It's a few months, it's a year!Master, the problem of demonic energy is solved, let's see if we can find the source of the demonic energy!"

Yang Hongqiu happily agreed, and Cheng Ling turned around, sensing the location of the demonic qi and groping forward.

But soon, he felt that this method was not working. After the demonic qi was sealed, the demonic qi rose sharply, and the sense of direction became confused.

They had to follow the same path all the way back until they had just entered the entrance to the mountain range, where they could catch the location of the demonic energy.

In this way, it is like going around in a big circle in the mountains, and a lot of time is wasted. And on the way to find the source of demonic energy, you can meet powerful spirit beasts from time to time.

These spirit beasts are different from the demon clan, because they have been eroded by demonic qi for a long time, and they almost have no sanity. But on the other hand, they are very strong in strength and even more tyrannical in temperament, and they will take the initiative to attack as soon as they find the traces of the two.

Fortunately, the cultivation of the two of them is very high, and their attack power is extremely strong, and they have survived many battles along the way.

On this day, they came to the location of a dense valley, and obviously felt that the demonic aura here was much stronger than that outside. Not only that, but the demonic energy that emanated around seemed to be absorbed by a powerful suction, and it was still converging.

Cheng Ling's heart suddenly sudden, slowed down and slowly walked into the valley. Suddenly, a dizzy sensation came through his mind, as if the whole world was spinning.

"Cheng Ling, something seems to be wrong, the whole space seems to be spinning, making me dizzy!" Yang Hongqiu stroked his head with his right hand, frowned, and said anxiously.

Cheng Ling's face changed greatly, and he hurriedly said, "Master, hurry up and quit!"

As soon as the words fell, I was about to retreat sharply! But the feeling of vertigo hit my soul, and my legs involuntarily moved in the direction of rotation.

Over there, Yang Hongqiu is the same, his body is already far away from Cheng Ling, and the rotating power seems to correspond, making the distance between the two gradually lengthen.

Cheng Ling stretched out his right hand, and the Long Ling sword came to his hand. The long sword was thrust into the ground, stabilizing his body, his divine sense swept back, and shouted: "Master, you and I work together, attack behind us with all our strength, we must leave this place immediately!"
