Time passed slowly like this, and in Du Fei's feeling, it seemed that more than half a year had passed, and it seemed that only a few days had passed. Because with the passage of time, in the end, the concept of time has become a little blurred in Du Fei's mind.

And because Du Fei deliberately restrained the power of the Heaven and Earth Yuan Dan in his body, the Heavenly Demon Qi that was wrapped around Du Fei's body had become more and more, and in the end, there was almost a feeling of penetrating the bone marrow.

However, even if Du Fei was a big one, he would not allow these Heavenly Demon Qi to completely erode him, so vaguely, he still urged the Heaven and Earth Yuan Dan Qi in his body to purify the Heavenly Demon Qi that had poured into his meridian bone marrow. It's just that, despite this, he still didn't move a single bit of the Heavenly Demon Qi that was wrapped around Du Fei's body and poured into his body.

Because, if Du Fei expects it well, if he wants to leave this place and enter the real Realm God Temple, I'm afraid that these days the demonic qi is the key. However, in the end, how things will develop, even Du Fei can't predict.

In this way, after walking in the black desert for more than half a year, the whistling Heavenly Demon Qi on the surface of Du Fei's body has reached an unimaginable level! If outsiders saw the horizontal and horizontal whistling on Du Fei's body at this moment, they could talk about the Heavenly Demon Qi that covered the sky and the sun, most of them would regard him as an extraterritorial Heavenly Demon, and most of them were still at the level of the Heavenly Demon King!

And it was when the Heavenly Demon Qi on his body had reached the level of the Heavenly Demon King, Du Fei, who was walking slowly, suddenly shook his body, and then his pupils shrank sharply, because, at this moment, he suddenly saw a towering black tower not far from him in front of him.

The Black Tower appeared in the sky so suddenly, as if it had existed since the beginning of the world! And on this black desert, there was an endless evil and black aura roaring out of the Black Tower, as if anyone who came into contact with this kind of aura would go crazy in an instant!

Such a black tower. Du Fei had never seen it before, but the roaring thick evil heavenly demonic qi in this black tower was the only one Du Fei had seen in this life! If Du Fei was not mistaken, the intensity of this heavenly demonic qi would definitely exceed that of any ordinary Heavenly Demon King, reaching an unimaginable level! Even if a strong person at the level of a martial saint was entered by such a heavenly demonic qi, he might turn into a demon slave in an instant!

There was really nothing wrong with what I guessed! Everything in this divine realm was really related to the extraterritorial Heavenly Demon Clan!

Even, Du Fei had a vague guess that perhaps among the other primeval eight clans, there was still an extraterritorial heavenly demon clan lurking, and the extraterritorial heavenly demon clan might have vigorously contributed to the opening of the Realm God Temple this time!

And if this is the case, the purpose of this extraterritorial Heavenly Demon Clan is really too easy to guess! Either they want to solve the peak powerhouse of the Ancient Eight Clans, or they want to rescue the sealed Heavenly Demon King from this Realm Temple, and the identity of this Heavenly Demon King may even be the same as the Heavenly Demon King in the Kyushu Battlefield and even the Reincarnation Cave Mansion, which belongs to the existence of the Nine Heavenly Demon King!

However, it is more likely that the extraterritorial Heavenly Demon clan wants to do both of these things at the same time, which is just by looking at the methods of the Phoenix Destroying King and the Phoenix Destroying King that day!

"Perhaps, in this black tower, there are extraterritorial heavenly demons?" Du Fei squinted and stared at the black tower in front of him, his footsteps slowly stopped, and then his eyes looked at the black tower in front of him with a little thought, if his guess was correct, I am afraid that the situation in front of him would definitely not be easy to handle.

"That's it, no matter what the other party's purpose is!, however, as long as this black tower is solved, you will definitely be able to find a way out of here!" Du Fei pondered for a moment, but he stepped out violently, and the place on the surface of his body instantly had the aura of the Heaven and Earth Yuan Dan, instantly clearing most of the Heavenly Demon Qi covering the surface of his body, and Du Fei's strength was also instantly restored to the peak.

It's just that Du Fei only purified the part of the Heavenly Demon Qi that affected his actions, and the Heavenly Demon Qi that was half a foot away from his body, Du Fei still didn't move him at all.

The Black Tower is actually not too far away from where Du Fei is, at this moment, under Du Fei's full strength, he suddenly saw the Black Tower approaching quickly, obviously it won't take long for Du Fei to reach the front of the Black Tower.

However, at the moment when Du Fei's figure was about to fall on the top of the Black Tower, he saw that the ground in front of the Black Tower suddenly cracked one after another, and then the figure of the Heavenly Demon Qi roaring across the surface of the body slowly walked out from the cracked ground.

"Demon slave!"

Looking at these dozens of figures, the corners of Du Fei's eyes twitched slightly, if he didn't guess wrong, if it weren't for the Heaven and Earth Yuan Dan Protector, his final fate would probably not be much different from these demon slaves in front of him.

And just after these demon slaves appeared, they saw that the heavenly demonic qi suddenly ran across the black tower, and then, a figure with endless evil exuding from the tower slowly walked out of the tower.

"Ho ho ho, as the so-called distant is a guest...... But this little friend has good means, no matter how you look at it, he can only barely be regarded as a villain, right?" The figure that stepped out was extremely young, and there was a trace of weirdness on his pale face, he stood in the sky like this, looked at Du Fei, and said with a smile.

Hearing this, Du Fei also knew that his disguise was seen through by the other party, and he didn't say anything more at the moment, but stepped on the soles of his feet, and the thunder on the surface of his body was vertical and horizontal, and it didn't take much time to purify the Heavenly Demon Qi that covered the surface of his body, but Du Fei's figure reappeared on the black desert.

"Bang Bang Bang-"

The Extraterritorial Heavenly Demon in the middle of the air stared at Du Fei, and a hint of appreciation flashed in the depths of his eyes: "The power of thunder can actually purify the Heavenly Demon Qi of our clan, it seems that you should have one of the Heavenly Thunder Pills in your body, right?" Very good...... I have a lot of demon slaves at the level of martial saints, but I really don't have a demon slave with Heaven and Earth Yuan Dan in my body, this king, today I want to set a precedent!"

As soon as the words fell, I saw a Heavenly Demon King suspended in mid-air, but he had already stepped out, and then he saw him pointing his finger towards where Du Fei was, and suddenly the dozens of demon slaves were instantly roaring towards where Du Fei was.

Looking at the Heavenly Demon King who shot at this moment, a hint of surprise flashed in Du Fei's eyes, but at this time, he didn't bother to talk nonsense, but casually raised his right hand and pointed towards the place where the nearest demon slave was!

"Boom-"

The thunder-transformed dragon roared out in an instant, and immediately purified all the heavenly demon qi on the surface of the demon slave's body, and the demon slave's body trembled and instantly turned into powder.

Obviously, after the infinite years, the bodies of these demon slaves have long lost all their vitality, and if it weren't for the Heavenly Demon Qi, it is estimated that it would be extremely difficult to even move.

"Although I don't know which Heavenly Demon Qi you are, but this kind of child's play is useless to me! I have killed even the Nine Heavens Demon King, let alone a few demon slaves?" Du Fei raised his head and sneered, and then this time he slapped his hands and snorted.

"Thunder Devour!"

"Boom-"

With Du Fei's soft shout, his body seemed to turn into a thunder god at this moment, and infinite thunder roared out from his body, transforming into various forms, and pounced on those demon slaves who came vertically and horizontally.

"Bang bang bang-"

These demon slaves who completely lost their consciousness were wiped out almost instantly under the sweep of thunder, and a loud sound represented the fall of a demon slave. However, Du Fei did not use all his hole cards in such a situation at this moment, he just used the power of the Heavenly Lei Dan to help him break the situation in front of him, as for the other Heaven and Earth Yuan Dan, it will be his biggest hole card in this temple.

"Thunder Dragon!"

After solving the last demon slave, Du Fei snorted coldly, and then pointed to the place where the Heavenly Demon King above the sky was.

"Boom-"

A huge thunderbolt roared out from Du Fei's body, and then directly transformed into a dragon thousands of zhang long, and then rushed towards the place where the Heavenly Demon King was located with unparalleled might, and everywhere along the way, all the Heavenly Demon Qi was instantly purified.

The Heavenly Demon King in mid-air also had a shocked look on his face at this moment, everything happened a little faster than he imagined, so that he couldn't react a little, and when he reacted, all his demon slaves had been solved by Du Fei! And at this moment, Du Fei actually came at himself!

"These nasty Heaven and Earth Yuan Dan owners!" The Heavenly Demon King's face changed in an instant, and as soon as he moved his hands, he was ready to use his martial arts.

It's just that when he saw the flying Heavenly Demon Qi in front of him, his complexion suddenly changed again, and he turned around and rushed towards the Black Tower behind him regardless of it, obviously this Heavenly Demon King understood that he would definitely not be the opponent of the guy in front of him.

"Wang, save me!"

At the same time, an exclamation came from the mouth of this Heavenly Demon King, but before his voice fell, the roaring dragon had already devoured his body in an instant, and he only had time to struggle for a moment, and his body instantly turned into nothingness!

And after purifying a Heavenly Demon King, Du Fei's offensive was still roaring forward.
