All the previous mysteries and all the doubts in his heart were all revealed the moment Du Feiyun recognized the breath of the black dragon.

Du Feiyun was less than a thousand feet away from the black dragon, and the black dragon was not concealed, so Du Feiyun could clearly sense its breath, so he recognized its identity.

Yes, that's right, the black dragon that was rolling endlessly in the black dragon's breath was the dragon guest officer who had not been seen for a long time! The person who entered the main hall before Du Feiyun was him.

At this moment, Du Feiyun suddenly had a lot of realizations in his heart, and he finally understood why the feeling that the dragon guest officer gave him had always been very mysterious. He had always been wary of the Dragon Guest Officer, because he knew that this person must have hidden his strength, and now he saw that he actually had the strength of the Divine Soul Realm.

What's more, and what Du Feiyun didn't expect was that the body of the Dragon Guest Officer turned out to be a black dragon! Moreover, looking at the appearance of the Dragon Guest Officer, he seemed to be very familiar with this dragon tomb, and he seemed to be breaking the seal of the Eight Extremes Heavenly Gate now, and cooperating with the black dragons on the side of the Dragon Realm Passage to completely open the Dragon Realm Passage.

"Spy! The Dragon Guest Officer turned out to be a spy who had infiltrated the Xuanhuang Shilu Realm! No wonder this person was hiding so deeply, it turned out that he was trying to infiltrate the Dragon Realm Passage in the Mitian Tower!"

Everything was finally clear at this moment, and Du Feiyun finally became angry, and a murderous aura was born in his heart. If the dragon guest officer wants to open the passage of the dragon realm and let the evil dragons of the dragon realm set foot in the Eastern Wilderness, it will definitely be a misery at that time, Du Feiyun does not have the idea and ability to save the common people in the world, but he is also angry at the despicable behavior of the dragon guest officer.

"Otherwise, once he is allowed to destroy the Eight Extremes Heavenly Gate, once the Dragon Realm Passage is opened, hundreds of millions of Li people and monks in the Eastern Wilderness will be turned into dust!"

In Du Feiyun's mind, there was the voice of the Shura Demon Emperor, and he was slaughtered, even though he was a generation of Demon Emperor giants. He has a deep grudge with the Xuanmen monks, but he can't bear to sit back and watch the dragon guest officer break the seal of the Eight Extremes Heavenly Gate. Only the Demon Dragon Emperor never spoke. Obviously, he was also very conflicted and hesitant in his heart. He not only hoped that the Dragon Realm Passage would be opened and that he would be able to enter the Dragon Clan's Holy Land World Realm, but he was also afraid that the Dragon Realm Passage would be opened and usher in a catastrophe.

Meanwhile. In the churning black dragon's breath, the black dragon stopped rolling. Turning his head and casting a glance at Du Feiyun, a trace of surprise flashed in the depths of his dark eyes, and he immediately stopped paying attention to Du Feiyun. continued to roll over his massive body. Swallowing those black dragon breaths, he attacked the pattern formation on the pedestal of the stone tablet.

The origin and identity of this dragon guest official is mysterious, and even now Du Feiyun can't tell whether he is a descendant of the black dragon or a dragon of the demon clan. However, I thought that the dragon guest officer was able to find the dragon tomb so quickly. Along the way, he opened many seals and formations to come here, seeing that he was so familiar with the Dragon Realm Passage. Apparently premeditated for a long time.

The black dragon's breath under the pedestal of the stone tablet became more and more intense, tumbling and swirling, the surrounding space was scorched and distorted, and the earth was also turning into black ashes little by little, spreading outward at a speed visible to the naked eye. Time is running out, Du Feiyun knows that Dao has now reached a critical juncture, and it will be too late if he doesn't stop Long Keguan.

Immediately, Du Feiyun didn't care about anything else, and with a roar of anger, he manipulated the mountain and river catalog, turned into a thousand zhang size, and flew towards the dragon guest officer. The mountain and river catalogue exudes a rich blue light, and the black dragon breath is set aside everywhere along the way, with a majestic majesty towards the dragon guest officer as a hood, among which the nine peaks and eighteen rivers are all moving and circulating, as if there is life, that is the power of the Shura Demon Emperor in the mountain and river catalogue, wanting to suppress the dragon guest officer.

When the dragon guest officer saw Du Feiyun coming here, he was also very surprised in his heart, and he didn't understand how Du Feiyun could come here with this little strength. His primary goal now is to destroy the seal of the Eight Extremes Heavenly Gate, and he can't delay it for a moment, otherwise when the guards of the Holy Dragon Hall find out that something is wrong and come here to investigate, then everything will be over, and his plan that has been planned for thousands of years will collapse. ...,

Therefore, he turned a blind eye to Du Feiyun's arrival, and continued to go all out to swallow the dragon's breath, bombarding and destroying the Eight Extremes Heavenly Gate Formation, while also increasing his strength extremely quickly. The dragon breath that overflowed from the crack in the Dragon Realm Passage was the purest black dragon breath, which was at least spewed out by the black dragon above the Transformation God Realm, which was of great benefit to the Dragon Guest Officer.

However, the mountain and river catalogue was extremely powerful, with an unparalleled momentum under the hood, even if the dragon guest officer had the strength of the Divine Soul Realm, he did not dare to ignore it, he could see that this mountain and river catalogue was a Dao weapon, and it was definitely not something he could compete with.

The dragon guest officer had to stop bombarding the sealing formation, and instead roared angrily, the black body of Qianzhang rolled and twisted violently, and the dragon tail with barbs shaped like a fish's tail swung violently, and swept towards the mountain and river catalog.

"Du Feiyun, if you don't go to the road in heaven, there is no door in hell for you to break in, this is you asking for your own death! Everything you did to the old man at the beginning, the old man has been holding back in order not to expose his hard work, and now the old man will settle the old accounts with you, let you see the real strength of the old man, today you will die without a place to be buried, and no one can save you!"

The dragon guest officer was also angry in his heart, time was extremely precious to him, but Du Feiyun made a move to prevent him from bombarding the sealing formation, with such an annoying fly present, he decided to sacrifice ten breaths of time to kill Du Feiyun, just to avenge his previous revenge.

The huge dragon's tail brought up a black hurricane, and even the space was about to collapse and collapse everywhere it passed, and the speed was even faster than lightning, and the majestic power swept in, even the peaks of thousands of feet were difficult to resist, and they were about to turn into powder on the spot. With this move, the terrifying strength of the powerhouse of the Divine Soul Realm was undoubtedly revealed, and even the Shura Demon Emperor was secretly frightened, he could see that the strength of the Dragon Guest Officer was only a trace worse than that of him in his heyday.

The huge dragon's tail slammed into the thousand-zhang-sized mountain and river catalog, and the cyan brilliance shrouded around the mountain and river catalog was suddenly scattered and splashed in all directions, and the huge dragon tail suddenly poked into it, and it was about to be photographed into pieces. At the critical moment, the Shura Demon Emperor shouted angrily in a low voice, urging the large array of the mountains and rivers catalogue with all his might, and the stored mana was instantly drained by forty percent, and the nine peaks and eighteen rivers suddenly spun and danced rapidly, and finally unloaded the power of the huge dragon tail.

The strong energy swept out, blowing the vast and desolate land into flying sand and rocks, and as soon as the dragon tail and the mountains and rivers catalogue separated, they each urged all their strength again, and bombarded together. At that moment, it seemed that the two sides had a draw, but in fact, Du Feiyun was still at a disadvantage.

The dragon guest officer twisted the dragon's tail, turned the dragon's head and pounced towards Du Feiyun, the huge head like a small mountain, a black flame was released, and the eyes were burning with terrifying purple fire, and it would spew out a mouthful of pure dragon breath with a big mouth. That black dragon's breath was exactly what it had just drawn from the crack in the Dragon Realm passage, it was an incomparably pure true dragon's breath fire, even the best Horcruxes could be incinerated into nothingness in an instant, and if Du Feiyun was stained, it would immediately turn into flying ashes.

At the critical juncture, the mountain and river catalogue swept in again, protecting Du Feiyun in it, and at the same time wrapping the dragon guest officer. This black dragon is full of black flames, only a Dao-level magic weapon can resist it, Du Feiyun has the intention to kill the dragon guest officer, but he knows that this is unrealistic.

Suddenly, Du Feiyun's heart moved, and he thought of a clever plan, so he informed the Shura Demon Emperor with the transmission of his divine sense, and both of them were refreshed by it, with a confident smile in their eyes. I saw that the mountain and river catalogue wrapped the dragon guest officer's head, wrapping its huge body and black flames in it, and then the eighteen big rivers in the mountain and river catalog suddenly jumped out of the picture scroll and turned into real hundred zhang rivers, like a silver-white jade pillar that reached the sky, pouring down towards the dragon guest officer. ...,

But all the monks who practice spells, whether they are demons, demons or humans, are all in the five elements, and the water in the five elements can overcome fire, so it is the best policy to use the eighteen great rivers in the mountain and river catalogue to suppress the dragon guest official.

Sure enough, the eighteen surging rivers formed a large net, wrapping the water of the river around Long Keguan's body, and the black flames suddenly scorched the infinite river water into water vapor, and the water vapor was suddenly filled within a radius of 100 miles.

At first, those black flames were still violent, enough to scorch and dry up the rushing water of the three great rivers, turning the sky into mist, but then they were finally exhausted, and they could no longer resist the invasion of the eighteen great rivers, and the black flames were finally extinguished.

Seeing that this method was really effective, the Shura Demon Emperor immediately showed a successful smile, and was about to manipulate the eighteen great rivers, bind the dragon guest officer among them, and then drag it to the mountains and rivers catalog to suppress it, but found that the dragon guest officer did not panic in the slightest, and did not struggle, but roared with his head held high and let out an arrogant laugh.

"Ha Luha, stupid, really stupid! Du Feiyun, it's just wishful thinking that you want to destroy me with water, have you forgotten the water dragon that you took me in the first place? The old man told you that the old man also has a double identity as the commander of the water army on the Dielang Cliff in the East China Sea! Your monstrous water vapor is an excellent help for the old man to display his magical powers, you are digging your own grave!"

Sure enough, as Long Keguan's words fell, I saw its huge body tumbling and twisting, and the eighteen rivers were all wrapped around its body, and at the same time, it opened its big mouth, and swallowed the eighteen rivers into its stomach like eating noodles.

The Shura Demon Emperor in the Mountains and Rivers Catalogue suddenly turned pale, and his eyebrows jumped violently, seeing that the eighteen great rivers were about to be swallowed up, and the Mountains and Rivers Catalogue would fall into silence, and he would not be able to use them again in the short term, he was really worried.

"Oh no, I didn't expect this guy to be a fire and water!" Suddenly encountering such a change, Du Feiyun was also annoyed, and the anger in his heart was even more intense.

"Ha Luha, Du Feiyun, you should die, it's time for us to break off!" The dragon guest officer roared, and then opened his mouth, only to see a black ball of water, wrapped in a cold air that was enough to freeze all the high-grade Horcruxes, and bombarded Du Feiyun fiercely.
