When Lu Yufeng and his party of seven walked through the Demon Mist Horn for five days, they didn't encounter any danger! As for the reason why the demonic qi contained a toxin, this was not a danger to everyone, after all, as long as the seven people didn't take the initiative to absorb these demonic qi, these demonic qi would not enter the body for a few days!

However, Rao was like this, and a few people did not dare to be careless, after all, this magic fog horn was extremely quiet, except for the sound of a few people stepping on the ground or dead leaves, there was no sound at all! Such a large forest, except for dense trees, there were no living creatures!

"Not far ahead, we are about to enter the real Demon Domain, everyone be careful!" A vigilant voice came out of Xiqing's mouth, and Lu Yufeng and the others immediately raised their vigilance, paying attention to any wind and grass around them!

Sure enough, when Lu Yufeng and a few people climbed over the mountain, they found a huge stone stele, on which the word "Demon Domain" was written crookedly! The stone stele was very mottled because it had been eroded by demonic qi all year round, and from the inside of the stele, it also revealed a strong demonic aura!

"This stone tablet has been eroded into a magic weapon by demonic qi!" Lu Yufeng looked at a few people and said in a deep voice!

Jin Yu and the others also nodded! It's a pity that the demonic qi on this stone tablet is also poisonous, otherwise, this stone tablet can be forged into a magic weapon of no low grade for any demon cultivator!

"Of course, the demonic aura here is so strong, even ordinary stones will become spirit stones, not to mention that the old man still takes care of this stone tablet every day!"

Suddenly, an old voice sounded from behind the stone tablet! Lu Yufeng and the others were immediately startled. Then the whole body of Zhenyuan swayed, revealing a vigilant look! Not only Lu Yufeng, but also Xiqing, also looked at the stele vigilantly!

"You don't need to look at it, can you still see the flowers on the stele?" The voice sounded again, and then, Lu Yufeng and the others saw that a monk with a black robe wrapped in his whole body walked out from behind the stele!

The monk's dress is somewhat similar to that of Xiqing!

"Who are you?" Xiqing said in a deep voice as she looked at the monk wrapped in a black robe!

No wonder a few people are so nervous, what kind of place is this? This is the Devil's Mist Corner. But a Jedi in the Demon Realm. How could a monk wrapped in a black robe suddenly appear? Lu Yufeng and the others also looked at the monk who walked out from behind the stone tablet vigilantly, because Lu Yufeng and the others couldn't feel any breath on this monk, if it weren't for this person standing in front of Lu Yufeng and the others now. Lu Yufeng and the others will still think that they are wrong!

This is also the reason why Lu Yufeng and the others didn't find this person in the first place!

Silent. There is no breath in the body. Even the breath of a mortal is not there! There is no breath of a monk, can Lu Yufeng and the others not be nervous?

There are only two such situations. Either the person in front of him wrapped in a black robe is a top monk, which has surpassed the cognition of Lu Yufeng and the others, or this is a species that Lu Yufeng and the others have not seen! However, it is obvious that the first situation is more reliable!

"Little girl, last time you came alone, this time, you also brought a few companions!" The monk wrapped in a black robe revealed an old face like tree bark, with folds all over his body, looking extremely terrifying! Then, the monk looked at Lu Yufeng and the others and said, "Yes, yes, it's still a few foreign monks!"

Hearing the monk's old voice, Lu Yufeng's expressions immediately changed, and then they looked at the monk in front of them with a solemn expression!

When Xiqing heard the old man's words, his expression changed even more, because Xiqing suddenly thought of a guess, and then said: "You are the demon of the monument guarding the world."

The old man heard Xiqing's voice, and then said: "It seems that you have seen a lot of little girl!

The old man looked at Xiqing, although his face was wrinkled, but in his eyes, there was indeed a flash of light!

The old man did not admit that he was not the so-called Monument Guardian Realm Demon, of course, he did not deny it!

Lu Yufeng and the others didn't know what the Monument Guarding Realm Demon was, but from Xiqing's shocked look, Lu Yufeng and the others could understand that this Monument Guarding Realm Demon must not be simple!

"It turns out that there really is a Demon in the Monument Guarding Realm" Xi Qing looked at the old man's expression, and immediately confirmed, and muttered in his mouth!

Xi Qing never thought that what he had seen in ancient books really existed! The Demon of the Monument Guarding Realm was really a legendary existence! Xi Qing had also seen it in the classics by chance! However, since it was the Demon of the Monument Guarding Realm, there was nothing to be afraid of!

"Senior, can you let us pass?" Xiqing looked at the old man and said respectfully!

"Of course you can, I didn't think about stopping you, but I still have a good word to advise, if it's not necessary, really don't enter the Demon Domain, because, with your current strength, it is difficult to survive in it!"

Xiqing nodded lightly, and then said, "However, we also have to go in!"

With that, Xiqing directly crossed the boundary monument and walked towards the Demon Domain!

Lu Yufeng glanced at the old man suspiciously, and then walked towards the Demon Domain as well!

Seeing the figures of Lu Yufeng and the others, the old man's wrinkled face showed a look of regret!

"Hey, a few more seedlings, just like this, stepping into the place of death!" the old man said with a sigh!

As he spoke, the old man turned into a phantom, and gradually disappeared like this, as if he had never appeared!

"Xiqing, what is the Demon of the Monument Guarding Realm?" Lu Yufeng caught up with Xiqing's figure and asked with some doubts! Lu Yufeng could see that Xiqing had great respect for that old man, as a Shura girl, even those strong people could not make Xiqing so respectful, who was this old man, and why could he make Xiqing like this? Lu Yufeng's heart was full of doubts, and he immediately asked!

A hint of respect flashed on Xi Qing's face, and then he said, "Actually, I don't know what the Monument Guardian Realm Demon is!

Immediately, Xiqing told Lu Yufeng and a few people what he knew!

It turns out that the Monument Guardian Demon is not a person at all, but a wisp of soul, or a shell!

It is not necessarily that the monk who has gone mad has not been saved, but after he has gone mad, he has been sent to the demon realm, and he is really not saved! Because, the demonic qi in the demon realm contains a toxin, and the monk who has gone mad does not have any consciousness, so he will naturally absorb the demonic qi in it, which causes the demonic qi to become more and more serious!

Of course, there have been no exceptions, in the history of the Demon Domain, there was once an ancestor who came to his senses after he went mad and was sent to the Demon Domain! Of course, this kind of sobriety also paid a great price! Because this ancestor forcibly stripped his soul and body!

This kind of detachment is different from the detachment of the soul out of the body, it is completely peeled off, and from then on, it is like two unrelated existences!

Although it is easy to say, however, Lu Yufeng and the others are very aware of the pain, of course, the point is that this is very difficult, at least, in the situation that Lu Yufeng knows, this is completely impossible!

"Therefore, this senior has become the stele keeper, and people call him the stele keeper realm demon, and he has always guarded the demon realm stele!" Xi Qing said in a deep voice: "If it is the one who has the deepest cultivation in the demon realm, it is definitely not the patriarch of the Demon Emperor Clan, nor those strong people who live outside the world, but this stele keeper realm demon!"

No one knows how powerful this monument keeper is, because he has never made a move! However, there is a rumor that the biggest reason why these demon cultivators who have gone mad and only know how to kill cannot get out of the demon realm is because of the existence of the monument keeper!

Can this monument keeper not be strong?

When Lu Yufeng and the others heard Xiqing's explanation, they were also shocked in their hearts!

"I didn't expect that in the Demon Domain, there is such a strong existence!" Lu Yufeng muttered at the same time in his heart......!
