A strange black mist suddenly appeared in the valley, only to see that this black mist is extremely thin, if you don't look closely, it is difficult to find in the colorful clouds, and its size is also extremely limited, only the size of a grinding disk, which enhances its concealment.

After this black cloud appeared, it drifted towards the direction where Liu Muqing was, its speed was extremely fast, and it did not have the slightest effect in this colorful cloud, and it appeared directly on Liu Muqing's right side after avoiding a lot of terrifying prohibitions.

Liu Muqing was unaware of this, he was slowly exploring the valley at the moment, but he didn't dare to get too close, he could only rely on some spiritual objects in his hands to explore the way, and even so, he found some extremely terrifying prohibitions, making him more careful.

"There was a big war in this place before it caused this kind of so, but after a big war, there are so many prohibitions appearing, it's unimaginable, I'm afraid this kind of prohibition method can only be arranged by immortals!" Liu Muqing thought secretly in his heart.

Walking and walking, a white jade-like jade bone suddenly appeared in front of Liu Muqing, this bone should belong to the leg bone, and it was crystal clear, as if it was a jade bone condensed for thousands of years, but it was more blessed with strong energy, but now it has dissipated a lot, and the energy contained in it has dissipated, leaving only the body.

Liu Muqing's hands were smashed together, and then a breeze formed under the jade bone, and then slowly condensed into the shape of a palm and directly incorporated it into his hand, he gently weighed it, and found that the weight was like a rock, and the tight bone made people feel extremely hard.

"This should be a person who has an extremely high cultivation of the art of body refining, and he can actually refine his own bones into jade, even if I am not good now, but I think that this person was strong back then, and his cultivation should at least be up and down in the Mahayana period!" Liu Muqing thought secretly in his heart.

However, just when he looked at the jade bone in his hand, a black mist suddenly appeared in the void, this mist seemed to have spiritual intelligence, and at this moment, seeing Liu Muqing pay attention to the jade bone in his hand, he couldn't help but escape directly, and then quickly shrouded him, so fast that people almost couldn't react.

Liu Muqing, who was looking at it, suddenly moved, and a brilliant golden light immediately burst out from his body, forming a thick golden shield around his body, and a purple thunder in the air was condensing at this moment, and the moment the thunder turned into a black fog, the black mist was shrouded in the middle.

"Although I don't know what you are, but if you attack me so blatantly, you are already my enemy, and since you are an enemy, you can't forgive!" Liu Muqing looked at the mist surrounded by thunder, with a thick sense of vigilance in his heart.

It's just that at the moment when the thunder surrounded the black mist, Liu Muqing was suddenly stunned, he thought that this black mist should belong to something spiritual, but what made him feel the difference was not the case, this black mist, there was not the slightest intelligence, and the only emotion contained in it was probably only one and that was devouring, instinctive devouring.

"What's going on? How could there be such a thing here, could it be that the devouring intent that the powerful monk exuded before he died was left behind, and then it has been preserved until now?"

But at this moment, the black mist rolled up, and turned into a huge mouth in front of his eyes, and the big mouth of nothingness bit at those thunders, and swallowed them in an instant, only to see that the black mist flashed with electric light, and disappeared after a while.

"There is such a thing, there is no wisdom at all, and there is no other means, just devouring instinct, this is a sharp weapon if it is used properly, the only trouble is that it is not so easy to capture this black mist!" Liu Muqing thought secretly.

However, at this moment, suddenly a huge spatial fluctuation appeared from a distance, as if someone had broken out into a fierce battle somewhere, and the colorful clouds and mist suddenly churned endlessly, and strange phantoms began to appear one after another, and unimaginable scenes appeared in an instant.

A passage through the sky and the earth is stored in the middle of the valley in the distance, with the passage as the center, countless forbidden techniques are stored on it, densely packed and extremely numerous, and each of these forbidden formations is extremely powerful, at least Liu Muqing has not been able to recognize one, and in the forbidden array, there are hundreds of monks hiding in it, they are all extremely special, floating like immortals, the strength is extremely terrifying, walking freely in this forbidden array, talking and laughing with some of the people who appeared in the passage, it seems that they all know.

"This is the passage of the fairy world back then, the immortals descended to earth by such a passage, no wonder there will be immortal qi here, and no wonder there will be so many strong corpses appear, it seems that I am not looking for the wrong place, this is indeed the passage of the fairy world!" Liu Muqing's heart couldn't help but be hot, and his eyes couldn't help but look at the center of the valley, only to see that there was the most condensed place of colorful clouds, making it impossible to see everything.

There are not many illusion fragments, and most of them are broken, and they are also hidden in the multicolored clouds, but the messages they convey are extremely useful, and the passages have gradually changed over time.

Liu Muqing found that after a period of calm time, the passage suddenly became busy, and those monks who guarded the prohibition often had to change the spirit stones of the formation once a day, and he also found that more and more immortals came down from the immortal realm, and then they had reached a peak, and countless immortals began to descend to the mortal world, but few immortals used this passage to return to the immortal realm.

After a period of time, the prohibition of this place was reinforced, and some monks who were obviously immortals took over this place, but this period was the peak of the operation of the passage, and countless immortals passed into the mortal world, and then disappeared here in a hurry, never to return.

"This should be the beginning of the war, I once heard Ying Yue say, before the arrival of the demon clan, they thought it was just a trivial matter, until the demon army descended, and they suddenly woke up after they controlled most of the mortal world with a sweeping momentum, and then they frantically sent troops down to earth, and this is also the beginning of the immortal and demon war, so the role of this passage before was to transport immortals, and his destruction was probably because of the sudden attack of the demon people!" Liu Muqing looked at the constantly changing picture in the sky, and secretly thought in his heart.

Soon every time it passed, the sky here was shrouded in darkness, and dozens of demon powerhouses raided here, they manifested their true bodies, each of them was dozens of zhang high, and their physical bodies were extremely strong, even some immortal weapons could not shake their bodies, and their bodies were like electricity, and they rushed into the front of the passage like a bamboo.

However, at this moment, a trace of determination suddenly flashed on the face of an immortal in charge of this place, and he waved his hand to strike a shocking spiritual decision, and then saw that this originally completely undamaged passage began to break inch by inch, and the terrifying explosion instantly destroyed this void a lot.

However, those demon powerhouses were unwilling to return empty-handed, several demon powerhouses did it together, and the black light converged in the sky, forming a huge black disc in the sky, which slowly prevented the shattering of this space, and even the passage connecting the fairy world was slowly revealed, and the broken energy was blocked by a strange energy.

However, what happened next shocked Liu Muqing, only to see the hundreds of immortals below burning their bodies one by one, turning into terrifying light clusters and rushing towards those demon powerhouses, they may not be as strong as those demon powerhouses, but under the effect of their self-detonation of their own bodies, those demon powerhouses couldn't help but retreat, the space was unstable again, and the passage gradually dissipated, under the repair of the laws of heaven and earth, the hole in the sky was slowly disappearing.

But at this moment, the demon gods who had reached the extreme below suddenly let out a roar in unison, and the huge divine fist blasted into the sky, sweeping across the void like a comet, and the next moment it directly hit the passage hole that was about to disappear, followed by an earth-shattering sound.

There was a trace of crack in the immortal passage that was about to close, and it could not be repaired, or even changed, and a trace of immortal qi continued to escape from it, as if it was a swimming fish.

The illusion was over at this time, and those demon gods consumed all their minds because of the final blow, and they died directly in it, which can also explain the source of the huge giant bones, and also explain the source of those white jade-like bones, these people are the former immortals and demon gods.

Liu Muqing couldn't help but sigh when he saw this, compared to the illusion he saw in the immortal tomb before, the illusion here is more real, and this place is the battlefield of the year, he seems to be able to see the heroic scene of those immortals desperately under him, the immortals who have been cultivating for hundreds of years and thousands of years have pounced and died with the demon powerhouse, this feeling is too tragic, and it is too unbelievable.

Seeing this kind of scene like him, there were also Jialan and Xue'e, the two of them saw this level of illusion for the first time, and they couldn't pull it out for a long time, and their faces were even more shocked.

"Buzz!"

Suddenly, a black mist appeared in the sky, and as soon as it appeared, this black mist flew straight towards the place where Liu Muqing was, and soon merged with the mist in the thunder, and it actually attacked him one after the other.

Seeing this mist flying one after another, Liu Muqing still didn't know what was going on. These black mist should be the remnants of those demon gods back then, they are unwilling to fail like this, and they turn into this kind of thing under the condensation of anger, and the spiritual intelligence that can be maintained after tens of thousands of years has been extremely rare, and some have slowly evolved some other instincts, but the disgust and hostility towards the human race are still innate, so when they see Liu Muqing, they are like mosquitoes swarming when they see blood.

After the two converged, they quickly engulfed the purple thunderbolt, and then flew towards Liu Muqing at an extremely fast speed, but in the blink of an eye, it was completely wrapped in a black fog.

Liu Muqing looked at the gradually thickening black mist, feeling the bad feelings that kept appearing in it, an obsession to completely possess his body, he couldn't help but smile coldly, and then saw a burst of fire between his fingers, and the golden flame seemed so dazzling in the darkness, like a bright light in the night.

At the moment when the golden flame appeared, those black mist suddenly shook in unison, as if they suddenly trembled, and they couldn't help but want to escape from Liu Muqing's side, and the mist quickly dispersed, escaping into the void and disappearing.

Liu Muqing's eyes burst out, his fingers turned into several brilliant lights and shadows in the air, and then condensed a strange character, the moment this character appeared, I saw him wave his big sleeves, as if he was dispersing, these characters were directly scattered into the void, and there was not much time, and a silent scream sounded in the void.

Liu Muqing breathed a sigh of relief, looked around, and slowly approached the center of the valley. Now that the area has been determined, and he also knows what happened 10,000 years ago, and knows more that there must be a lot of immortal qi in this central area, he must take a walk.

Fortunately, his Buddha fire has a strong restraint on the people of the demon race, if it weren't for this, he wouldn't dare to go deep into it, but even so, he didn't dare to be careless, after all, there were many prohibitions in the periphery before this, who can guarantee that there are no prohibitions left in this central area, if there is really such a thing, even if there are ten, he will definitely be buried in it.

The clouds and mist rolled, and some phantoms continued to emerge in the colorful clouds and mist, some of which he had seen before, and some of which he had not seen before, and even some of the immortal secrets had a certain appearance in this, but unfortunately they were often fleeting, and there was no possibility of even imprints, so he could only sigh with admiration.

On the surface, the hard earth is like King Kong, there is no grass on it, but a crystal-like brilliance emerges, which is extremely hard and terrifying, this is a kind of spar that has a great reputation in the spiritual world and the fairy world, Jinshui Stone, known for its hardness.

But even such a crystal has become fragmented under the terrifying mana, and the terrifying sword marks are condensed in it, as if you can still feel the terrifying sword intent of the owner of the sword marks, and the huge palm prints, like the palms of giants, are surrounded by demonic energy, which should belong to the strong people of the demon race.

"Whew!"

A light breeze suddenly blew, making him feel cold, Liu Muqing couldn't help but be shocked, the scales on his body began to appear layer upon layer, and a pink orb hovered around him in his storage bag.

With Liu Muqing's strength, it is not cold and heat, even if the polar ice and snow and flaming magma are poured on his body, he will not feel the slightest feeling, but just after he took a step, there was a feeling of chill in his back and chills all over his body, which made him instantly understand that there must be a great existence hiding in it.

He looked around vigilantly, and pulled three talismans between his fingers, these three talismans are his most powerful runes, and their power is equivalent to the blow of a weak powerhouse, although he doesn't know if he can stop the other party here, but he can only be a dead horse as a live horse doctor.

"With my Immortal Sect inheritance, are you a disciple of that sect?"

Just when Liu Muqing looked around vigilantly, suddenly a cold voice sounded in the sky, and then the colorful clouds and mist automatically dispersed, and an ethereal figure slowly appeared from the clouds, and it was only at this time that Liu Muqing found the other party's figure.

Looking at the other party, Liu Muqing couldn't help but swallow a mouthful of spit, this woman gave him the feeling of extreme danger, as if he could crush him to death with just a move of his fingers, and he was sure that the other party was definitely not a real being, it should be a wisp of divine consciousness incarnation, but he didn't know why he could still survive in it.

Liu Muqing replied cautiously: "The younger Bai Yujing mortal heir, Liu Muqing, has seen a fairy!"

The woman's eyebrows and eyes in front of her were blurred, and her body was also white, and she could only vaguely see some outlines, and her gender could be determined from the voice, but she couldn't see what her face was like.

"Bai Yujing...... Bai Yujing...... Bai Yujing in the sky, five cities on the twelfth floor, immortals touch my top, knot hair and receive immortality!"

After hearing the three words Bai Yujing, the woman first felt a little confused, as if she had never heard it at all, but as time went by, she actually thought of some of them, and even said some poems in Bai Yujing, which made Liu Muqing happy.

Liu Muqing couldn't help but be happy in his heart. Listening to his tone, he should have an old relationship with Bai Yujing, otherwise how would he understand Bai Yujing's poems, and he also has a feeling of nostalgia in his heart, he must have had a relationship with him in the fairy world back then.

"This origin is indeed there, it's just a bad fate, I also made an oath back then, I want to kill all the disciples of your White Jade Palace, especially that young master, I will kill him!" the woman said lightly, as if she was telling an extremely ordinary matter.

But in this instant, Liu Muqing only felt like he was turning around at the threshold of death, especially when the other party could instantly listen to his inner thoughts, which made him feel even more naked standing in front of her, which was extremely uncomfortable.

"Don't worry, I'm a dead person, I won't do more killing, this place is not something you can come from this kind of cultivation, the future is full of twists and turns, almost everywhere can ask for your life, it's better for you to leave early!" The woman's voice came again, and after a warning, she was about to turn around and leave.

However, Liu Muqing was unwilling to give up, he couldn't get here, how could he empty into Baoshan and turn back, seeing that the other party was leaving, he hurriedly said: "Fairy, please stay!"
