The red sand stream has been reverberating in this valley for more than 2,000 years.

Fortunately, the spirit ore in this Red Desolate Abyss is the top hard ore in the Immortal Domain, and at the same time, the mineral reserves are also amazingly large, so they can trap this terrifying vision of heaven and earth here.

The divine light around his body was dense, and there were five swords and one seal floating around, Xu Cheng had already exhausted his hole cards, made complete preparations, and finally walked into the red wilderness.

Yan Yifeng stood behind Xu Cheng, he had never seen such a cautious Xu Cheng, or rather, there had never been an enemy before, which was enough for Xu Cheng to show his true nature.

Yan Yifeng looked at the five swords and one seal, and he recalled the story Xu Cheng once told him:

Xu Cheng woke up from the memories of another world and found that he had become a young master of a martial arts family.

In fact, his story after that was the same as what he experienced in the Qingling Gate back then, he also started with martial arts, and then fell silent for a long time.

But fortunately, the real Xu Cheng finally broke through the limit of martial arts, entered the immortal from martial arts, and successfully entered the immortal cultivation group.

After that, every time he crossed a realm, Xu Cheng's sword would be replaced, and from foundation building to divine enlightenment, there were already five immortal swords.

What is used in the Qingling Gate is the transformation of mortals and the mortal blades that build the foundation in the middle.

In this Desert State, the wood-grain jade sword used by Xu Cheng was indeed the exclusive fairy sword refined by Xu Cheng after he was promoted to the Divine Enlightenment Period.

However, the current Xu Cheng can use every sword he used before to use his unparalleled amazing power.

Coupled with the divine seal of Yuan Tiandao, this is all Xu Cheng's strength.

Now that the hole cards are out, Yan Yifeng understands that the next road is no longer something he can follow, even Xu Cheng, who is almost invincible in his heart, will definitely find it difficult to get benefits.

"Uncle Cheng......"

Seeing that Xu Cheng was about to leave, Yan Yifeng wanted to say something, he wanted to say something, but why did Xu Cheng need his advice?

However, Xu Cheng understood Yan Yifeng's thoughts, turned around and smiled slightly, and said indifferently as before: "Don't worry, I will bring the cloud back ......."

After speaking, Xu Cheng paused for a moment, and then said: "If I don't return here after a month, then you will go back to the Eastern Wilderness City first, take Moling and then go back to Fengchuan Prefecture, and finally I need to trouble you to tell Yan Khotan that I have probably failed." ”

"Uncle Cheng, you don't actually have to ......"

Yan Yifeng wanted to say something, but Xu Cheng raised his hand to stop him, then turned around and resolutely walked towards the Red Desolate Abyss.

Yan Yifeng stood in place, Mu Ran watched Xu Cheng leave, until Xu Cheng's figure disappeared into the black mist of the Red Desolate Abyss, and the sand flow that permeated Xu Cheng's aura fluctuations were completely covered.

Xu Cheng, who walked into the Red Desolate Abyss, didn't know that he could actually ignore Yan Zhiyun's remnant soul.

In the end, Yan Zhiyun is just a mortal, Xu Cheng has tried his best to preserve Yan Zhiyun's body and soul for decades, which is actually for a person who cannot enter the immortal path, and it has been most of his life.

But Yu Li, if Xu Cheng made a move one minute earlier, Yan Zhiyun would definitely not have an accident, Yu Qing, Xu Cheng escaped into the world, colluding with countless causes and effects, if he didn't care about the cause and effect in front of him, then it would be absolutely useless for his cultivation.

Besides, in this strict life world, Xu Cheng knows that he will never have to live in just a few decades.

It can be seen from Yan Yifeng's cultivation speed that although the two brothers are not good at immortal seeds, and the five elements of the immortal vein and the immortal soul cannot fully correspond, their comprehension is definitely not weak.

And with Xu Cheng's guidance, there is a high probability that there will be no obstacles in the various passes before Xuanyan, and the immortal soul can also find something compatible with each other, which is a great opportunity for the majority of middle and low-level cultivators.

Therefore, Xu Cheng wants to solve this cause and effect, and wants to completely resurrect Yan Zhiyun, so that the two brothers can work together in the future and forge ahead on the road of cultivating immortals.

Thinking like this, Xu Cheng had already crossed the periphery of the Red Desolate Abyss, crossed the ravine, and came to the core area of the Red Desolate Abyss.

The mountains were already rising, but the surroundings were getting darker.

Xu Cheng, who could still see a little sunlight, was now completely caught in the strange scene brought by the dark red and dark yellow of the desert sandstorm and the pure darkness brought by the Void Qi Shock.

The more he climbed to the top of the mountain, the more difficult it was to resist the pressure and impact of the Red Qi Sand Flow, and Xu Cheng needed to start continuously inputting spiritual power in order to maintain his smooth progress.

However, the continuous output of strong spiritual power also continued to attract the Red Qi Sand Stream to surging towards him in a large area.

Even from the outside, the rolling red sand stream is already similar to a black dust python, constantly searching for prey in the mountains, and the sound of shaking the mountains and rocks is echoing repeatedly.

Further along, the red sand flow was as dense as substance, and Xu Cheng knew that relying on the passive defense of five swords and one seal, it was no longer possible to climb the mountain.

Now he must take the initiative to open up the road to the peak in a sand flow.

"Zheng!"

Xu Cheng's fingers were raised slightly, and under the manipulation of his mind, the most simple Fan Tie long sword suddenly rose up.

The long sword named "Yu Qing" is a mortal sword used by Xu Chenggang when he crossed to his current body.

At that time, Xu Cheng was still a descendant of the Yu family, a martial arts family in the mortal world, and his name was Yu Qing.

Xu Cheng inherits Yu Qing's memories and knows Yu Qing's secrets, he needs to take Yu Qing's secrets to fulfill his long-cherished wish for him, and he also needs to find out where Zhang Mo in this world has traveled to.

However, Yu Qing's body has been affected by the true qi of martial arts since he was a child, and the aura that he cultivates will always pass with time.

After Xu Cheng ran out of time, after several trials that almost lost his life, he relied on the feet of mortals to walk through countless mountains and rivers in Junzhengzhou, and finally when his life was about to come to an end, he realized the key to the harmony of the five elements of the wonderful sword.

And with this mortal sword, he cultivated into a golden sword, successfully broke through the limit of martial arts, and stepped into the immortal path.

In order to commemorate the identity of Yu Qing, Xu Cheng renamed this mortal sword as Yu Qing, and developed the swordsmanship Taoism, reflecting the world, mountains and rivers comprehended by Yu Qing as a mortal, and all things in the world.

Therefore, at that time, the sword moves made at the Qingling Mountain Gate would have the phantom of mountains and rivers and spirit beasts and birds.

Now, Yu Qingjian once again lit up with blue and white sword light, and the virtual images of countless mountains and lakes and beasts condensed from the sword light, rushing straight into the red sand stream.

As a sharp Jin Xing Spirit Sword, almost instantly, it forcibly broke through the package of the sand flow, and forcibly cut out a narrow road up the mountain that was about several miles long.

Xu Cheng saw the opportunity, and suddenly the sword accelerated, and it was almost a few breaths before he was about to pass through the passage.

However, at this moment, the power of the red sand flow soared, like a giant python, and the situation of all the sand flows turned around, constantly reversing together, wrapping Xu Cheng in it again.

Xu Cheng saw that he was about to hit the dense wall formed by the sand flow, but Xu Cheng's speed did not change in the slightest.

He just moved his mind, and Yu Qingjian, who was originally indomitable, immediately converged his aura and returned to the talisman sword formation, and a simple and unpretentious, introverted bladeless gray thin sword flew in front of Xu Cheng.

This thin sword is really inconspicuous, but the slender sword body inexplicably looks extremely calm.

The next moment, the sword light of the thin sword was pulled by Xu Cheng's spiritual power, and it suddenly burst into disarray.

It was a grayish-yellow color similar to that of the dust of a desert sandstorm, but relatively more of a cool gray of alpine boulders.

After the sword light expanded rapidly, it instantly retracted, but it was not collected in the sword, but there was an extremely conspicuous layer of mountain phantom condensed around Xu Cheng's body.

Xu Cheng relied on the mountain to hold his body, and directly crashed into the high-strength giant wall formed by the red sand flow.

In the midst of the giant wall, Rao is Xu Cheng's cultivation, but he also suffers from an indescribable sense of oppression.

The endless stream of sand squeezed in, but fortunately the mountain phantom was strong enough to protect him from being crushed into powder as he walked for nearly a quarter of an hour.

This thin sword was refined by Xu Chengjindan.

At that time, Xu Cheng, in order to make up for his cultivation speed, chose the next Five Elements Magic Sword, which was an earth practice that would help Jin Xing grow.

He visited the famous mountains and rivers in Junzhengzhou, or borrowed or begged or desperately seized it, and finally collected 66 mountains and stones, and finally refined this "Zhenxin" sword with outstanding spiritual power.

Xu Cheng wants to use this sword as a discipline to suppress his gradually manic Dao heart, and he also wants to suppress all the Dao techniques that come to him in the fighting method.

Xu Cheng relied on the amazing defense of the Zhenxin Sword to successfully rush through the giant wall of sand flow.

But how could the red sand stream that seemed to breed spiritual wisdom let Xu Cheng go, only to see that the sand and stones were useless, and the void qi gathered silently.

The eternal void that grows from the void has the ultimate coldness and emptiness.

Under the erosion of the void, all things will return to loneliness, and finally dissipate into the formless, assimilated by the void.

Only the colossal spiritual power and special spiritual objects can be protected from the erosion of the void.

Since ancient times, Taixu has been the enemy of all living beings.

Now, the void qi in the entire red sand stream seems to be concentrated around Xu Cheng.

Rao is Xu Cheng's hidden spiritual power is amazing, and it is inevitable that it will be continuously eroded by the void qi accumulated for thousands of years.

This erosion is not only physical, but also psychological.

Xu Cheng was flying in the sky, but he was flying slower and slower, and in the end, the road in front of him became nothing, darker than the night.

Xu Cheng felt that he was constantly falling, until the last moment, he was about to fall into a veritable abyss, when suddenly a mighty long sword with a fire cloud pattern floating on the sword body suddenly flashed with endless fire.

It is precisely because of this that Xu Cheng's eyes have also recovered from the blurred void to infinite light.

Xu Cheng grinned, reversing the previous action of the sword, but directly holding the Fire Cloud Long Sword, and the dazzling flames burst out all around his body at the same time, fusing with the long sword, like a flying fire meteor, instantly cutting through the darkness of the void, and rushing into the ordinary sand flow of the Void Qi decreased.

Xu Cheng then put the Huoyun Sword back into the sword array, and once again used the sharpness of Yu Qingjian to open up a way forward.

This long sword engraved with fire cloud ornamentation, the birth idea is no different from the Zhenxin Sword, but Xu Cheng wants to choose the fire line that breeds the earth line.

And it is the main peak of Xu Cheng's famous Tianlun Dao Palace in Junzhengzhou, which is made of melting gold by forging Jiuyan with the cloud flame of the heavenly wheel.

At that time, Xu Cheng had already entered the Yuan Heavenly Dao, and he was a well-known Infant Liberation Realm monk in the surrounding cultivation world, Xu Cheng needed a fairy sword that was enough to shock the group of cultivators, so that he could not be afraid of any opponent.

That's why this "heavenly cloud" was born.
