There are no wonders in the world, hundreds of millions of species are always different, each has its own peculiarities, and Du Feiyun also knows this truth.

Before, he was curious about the life form of the Heavenly Demon, but now that he has seen the real thing, he finally has a deeper understanding of the Heavenly Demon. Although the appearance of these black crystal nuclei is not very good-looking, their effect is incomparably huge, because they contain the purest and richest aura, which is the essence of the Heavenly Demon's lifelong strength, so if they can be refined, it will be of great benefit.

It's a pity that ordinary monks can't directly refine this crystal nucleus, and it won't work without exclusive secrets and methods. Moreover, these crystal nuclei can not only be directly refined, but can also be used as an excellent material for refining magic weapons, and the reason why the Holy Dragon Temple collects a large number of such crystal nuclei is because they have mastered the knack of refining magic weapons with crystal nuclei.

At the same time, Du Feiyun also knew that another little-known use of the crystal nucleus of the Dao Dao, that is, it was used for alchemy, as early as a long time ago, many contents on the Lieshan Pharmacopoeia were memorized by him, and he knew that the Lieshan Pharmacopoeia had recorded a kind of pill that existed in the ancient period, called Shangqing Dan, and its main material was the crystal nucleus of the Heavenly Demon. With the Heavenly Demon Crystal Nucleus as the main material, equipped with nine common Heavenly and Earth Treasure medicinal materials, you can refine the extremely precious top-level soul-level pill Shangqing Dan, it is said that after taking this Shangqing Pill, it can increase the power of several years out of thin air is ten years, which is of great benefit for strengthening the meridians of the body, refining the Yuan Shen Fa, and enhancing the cultivation of the mind, and at the same time, it can also quickly heal and recover after being seriously injured.

In the primeval period, the Shangqing Pill was already an extremely precious pill, almost the same as the preciousness of the Yiyuan Pill, and only the powerhouses above the Transformation God Realm had the ability to use it, but now the Dan Fang has long been lost, and I am afraid that no one in the Xuanhuang World Realm knows about it except Du Feiyun.

Before coming to the Yongning Mountain Range, Du Feiyun had already planned to hunt the Heavenly Demons, and after obtaining the crystal nucleus, he would try to refine the Shangqing Pill, but now was certainly not the right time, so he collected all the one hundred and fifty crystal nuclei into the storage space in the Nine Dragons Ding. Wait for the war to go to the refining again.

Ten Heavenly Demon Squads were completely wiped out in just a few breaths, and instead of shaking back those patrolling Heavenly Demons on the outskirts of the mountain range, this result only angered them, causing them to frantically gather together and rush towards Du Feiyun and the others. It's completely a jade burning frame, and it seems that these heavenly demons never know what to fear.

The follow-up monks also came one after another, and many monks left the flying boat and appeared in the sky above the Yongning Mountain Range, and in the blink of an eye, the situation in the field was turned upside down. And now the monks on dozens of flying boats have arrived, and more than 10,000 monks have appeared in the air. The contrast between the forces of the two sides was suddenly reversed.

As if it was a suicidal act, those heavenly demons did not stop at all, they rushed one by one, condensed together and converged into a huge black mist, which was like a big net covering the sky and the sun, and they covered Du Feiyun and the others.

The more bold people are, the more courageous they are, and in normal times, almost no one dares to face the combined attack of thousands of heavenly demons, and there are more than 10,000 monks present at this time. But no one felt afraid, those heavenly demons were only equivalent to war trophies in their eyes. However, the people were excitedly sacrificing the magic weapon. When they were about to join forces to kill these Heavenly Demons in one fell swoop, Wu Yazi of the Holy Dragon Hall and Yanyunzi of the Taiqing Sect frowned in unison, feeling that something was wrong, and while teleporting forward, they did not forget to warn: "It's not good, everyone retreat, these Heavenly Demons are about to blow themselves up." ”

Sure enough, Du Feiyun also noticed that the aura of these Heavenly Demons was very violent, and now he saw the situation and suddenly understood. The thousands of Heavenly Demons rushed towards them. The body of the black mist was constantly expanding and bulging, and the black crystal nuclei inside the body were also compressing sharply, and the aura that gathered their lifetime mana was brewing, and it would burst out at any time. ...,

Yanyunzi and Wuyazi were powerhouses of the Divine Soul Realm, and they showed a strong adaptability at this moment, appearing in front of everyone a few times ago. Lying between the Heavenly Demons and the people. The two of them joined forces to display their great magical powers, one holding a sword and the other holding a whip in front of them, and immediately swayed the majestic mana, forming a multicolored wall that was thousands of feet high and tens of thousands of feet wide in everyone, which was an almost transparent mana barrier.

In the next moment, the thousands of Heavenly Demons rushed to the mana barrier, and at the same time, their violent aura reached its peak, and it suddenly burst open. I saw that the black mist that was thousands of zhang square suddenly condensed to the size of a hundred zhang, and then expanded to tens of thousands of zhang in an instant, and there was an incomparably majestic black cloud suddenly gushing out, like a black mushroom cloud blooming with a bang.

The extremely dull roar sounded instantly, only to shake the Nine Heavens Universe with a rumbling sound, and the nearby hundreds of miles of sea immediately rolled up dozens of zhang of huge waves, and even the space was shattered, revealing countless black cracks like fishing nets, and a black wind as cold as a knife rushed out of the cracks, tearing the colorful mana barrier fiercely, and bursting out with a piercing sound like nails scraping glass.

The self-explosion of the Xuanmen monks is at most just a self-detonation golden pill or a yuan infant or the like, and few people specialize in cultivating the corresponding self-detonation exercises. However, in the magic power of the Demon Dao, there is a self-detonation technique called Heavenly Demon Disintegration**, which is a self-detonation method born from the Heavenly Demon, so that when it self-destructs, it can burst out several times more powerful than itself.

How terrifying is the power of thousands of Heavenly Demons to self-detonate together? What's more, the Heavenly Demon Clan has a unique talent and advantage for self-detonation, even if it is a Heavenly Demon with the strength of the Yuan Dan Realm, when they self-destruct, they may seriously injure the Yuanying Realm monks, so the power of these thousands of Heavenly Demons to self-detonate is beyond everyone's imagination.

The multicolored barrier could only resist the black mushroom cloud for only one moment, and the next moment it shattered into countless fragments and was engulfed by the black mushroom cloud. Immediately after that, the mushroom cloud expanded indefinitely, spreading out in all directions, and wanted to sweep many monks into it. There is no doubt that this black mushroom cloud is more terrifying than the black hole and the abyss of time and space, but any monk who is swept into it will not be able to escape even if he has great ability.

Yanyunzi and Wuyazi were at the forefront, and after the mana barrier collapsed, they didn't dare to block the power of the self-explosion, and their bodies flashed and teleported into the distance. Du Feiyun and the others also sensed the fear of the mushroom cloud, and immediately teleported out ten miles away, not daring to risk their lives.

However, because those monks had just gotten off the flying boat, it was when the momentum was like a rainbow, and they couldn't accept the result of the Heavenly Demon being so strong for a while, some people reacted quickly and fled early, while some people were not so lucky, and they were swept into the black cloud when they couldn't escape, and their figures were completely engulfed, and they never appeared again.

After a full ten breaths, when the black cloud and mist swept through a radius of several miles, the power gradually spread and weakened, and then Yanyunzi and Wuyazi united many powerhouses to resist and suppress it, so as to prevent more monks from encountering the danger of falling.

The periphery of the Yongning Mountain Range finally became quiet, the black clouds and mist gradually dissipated between the heavens and the earth, and the scene of clear water and blue sky reappeared, but the hearts of many monks were cast a shadow, and their faces became very unsightly. Fang Cai and everyone left the flying boat one after another, landed on a mountain peak on the periphery of the Yongning Mountain Range, rested a little, and also counted Fang Cai's losses.

After the results of the losses were counted, the hearts of many monks became heavy, and the crowd could no longer hear the loud talk and laughter, and everyone asked themselves in their hearts, can we defeat the Heavenly Demons here, can we return to the sect alive?...,

Because, it was the self-explosion just now, they had never fought head-to-head with the Heavenly Demon at all, and they had lost thousands of people in vain, all of them were monks of the Jiedan Realm, and they were all elite disciples in the ten major sects. It's just on the periphery of the Yongning Mountain Range, and those small fish and shrimp-like heavenly demons blew themselves up, killing thousands of monks, so what will happen if you go deep into it next?

With such worries and worries, everyone marched towards the interior of the Yongning Mountain Range after resting, this time everyone's goal was the canopy that covered the sky, the canopy shrouded the central area of the Yongning Mountain Range, and the vast majority of the heavenly demons were hidden in it, and the goal of the monks was to destroy this canopy, kill all the heavenly demons in Yongning Mountain, and finally find the entrance to the space passage.

The closer they got to the gray billowing clouds, the more gloomy the mood became, and their faces became more and more ugly, and many of the weaker monks were pale, and beads of sweat appeared on their foreheads, and they actually stopped standing in place, their eyes staring straight ahead, and their eyes widened as if they had seen something extremely terrifying.

Du Feiyun didn't know why he suddenly felt a little upset in his heart for no reason, it seemed that there was a fire of ignorance running around, and there was nowhere to vent, which made his chest rise and fall slightly, and his fists clenched involuntarily. Ning Xuewei, Luo Huali and the others beside him also turned flushed, with a look of anger or fear on their pretty faces, and their bodies trembled slightly.

"What's going on? Why do you have a feeling that the demons are coming, and you are about to move, is it the heavenly demons here?"

Du Feiyun, who knew his own situation very well, quickly thought of this possibility, not only himself, but also the performance of the people around him, all of them seemed to be the reaction of being invaded by the demons during the catastrophe.
