"True Demon Qi, how can there be True Demon Qi emitted in this cave, although this True Demon Qi is not too strong, but this is too strange. ”

The spiritual sense carefully scanned the Baizhang Demon Cave, and Li Mu looked at Li Chongtian with a puzzled look.

"This is the Demon Suppression Cave, do you know where this cave is connected?"

Since Li Chongtian came to this valley, his eyes have never left the black demon cave, and he said in a solemn tone.

"You say it's called the Demon Suppression Cave? This cave looks very weird, and the true demon qi is exposed, could this be connected to the real demon realm, right? Or is there a terrifying demon suppressed inside?"

Xiao Tian's eyes rolled, and then he guessed.

"You guessed it, that's right, this Demon Cave is connected to the True Demon Realm!"

"This cave was left in the battle of the ancients, when the demons had a group of supreme powerhouses, and the top figures of my Beidou, an earth-shattering battle broke out in this Fallen Demon Valley. ”

"That battle can be said to be unprecedented, although the number of people participating in the battle is not large, but one by one they are all top powerhouses, you know, in ancient times, this place was not such a valley, but a group of mountains. ”

"That battle not only leveled the countless mountain ranges here, but also disrupted the laws of heaven and earth in this area, especially the laws of space, which were extremely unbalanced. ”

"The laws of heaven and earth are chaotic, and the laws of space are unbalanced, and the final result is that the broken space here can no longer be healed, so the spatial cracks are continuous. ”

Li Chongtian obviously had a deep understanding of the origin of this Fallen Demon Valley, and he opened his mouth to explain to Li Mu and the others.

"I've heard a little about these before, but I don't know so much about them, by the way, what's going on with this demon cave, how can it be connected to the true demon realm, and why are the spatial cracks in this place gone?"

Li Mu continued to ask.

"Speaking of this magic cave, the battle that broke out here back then was mainly caused by it. ”

"The ancient demon tribulation is not much different from the current situation, and the demon clan also invaded my Beidou through the spatial strongholds established everywhere. ”

"But you may not know that establishing a spatial stronghold is actually very resource-intensive, and the more spatial strongholds are established, the greater the consumption, and it is not a one-time consumption, but it needs to be consumed all the time. ”

"Let me explain to you this way, this spatial stronghold connects the True Demon Realm and my Beidou Realm, which is actually equivalent to using the formation to open a void channel between the two interfaces. ”

"First of all, it is very difficult to open such a void channel, and after opening it, it is not easy to maintain it from collapsing and disintegrating, just like a cross-border teleportation array, which needs to be maintained continuously. ”

Li Chongtian explained this and paused.

"Oh my God, this cross-border teleportation array is activated once, and it will consume a huge amount of resources, and the farther the two places are separated, the more it will be consumed, which has always maintained the state of excitation, and the amount of resources consumed, I can't imagine it now!"

Li Mu couldn't help but swallow a mouthful of saliva when Li Chongtian said this, he could already imagine the scene of consuming resources like flowing water through his imagination.

"You think so too, you know, the space strongholds left by the demons in my Beidou Realm are not one or two, so many strongholds consume resources all the time, even the true demons who often expand and plunder externally, are unbearable. ”

Li Chongtian said with a wry smile.

"That's not right, why do the demons have to invade my Beidou in the form of a space stronghold, isn't it okay to cross the border teleportation array, they have so many demon saints, and there are not a few who have cultivated out of the realm space, not to mention that there are also space spirit treasures, let them teleport over with people." ”

"This is simple and convenient, and the resource consumption is less, with the strength of its true demon clan, it is not difficult to build a few cross-border teleportation arrays. ”

Li Mu raised a question in his heart.

"Of course not, wood, how can things be as simple as you imagined, you forget that heaven and earth have laws and order, and it is nothing if a person crosses the border as long as he pays a price, but with many people crossing the border together, there will be big problems. ”

"The specific mystery of this is a little difficult for you to understand now, so let's explain it to you, for example, if you ascend to the immortal realm, if you cultivate to reach the pinnacle, you can naturally break the shackles of heaven and earth and enter the immortal realm. ”

"But if when you ascend, you take thousands of people in the realm space to ascend together, then wouldn't it be too easy to ascend to the immortal realm. ”

"There is also the suppression of the power of the law of the interface, which is also a kind of restriction of the law of heaven and earth, in short, you just need to understand that if the true demon clan wants to invade Beidou, you need to pay a great price. ”

Before Li Chongtian could explain, Xiao Tianlu suddenly interjected.

"I understand, to put it simply, the true demon clan must be invaded by the way of the space stronghold, other methods can't, if there is, it would have been used a long time ago, that's what it means, father. ”

Li Mu understood a little, he looked at Li Chongtian and said.

"Yes, it's not right, this Demon Suppression Cave in front of us is actually the second method that the demons can invade my Beidou Realm, but they didn't succeed in implementing it back then. ”

"This Demon Cave is actually a spatial stronghold, but this spatial stronghold is different from ordinary spatial strongholds, once it can really be opened, then it is equivalent to opening up a permanent passage between the True Demon Realm and my Beidou Realm, and it is a channel that does not need to continuously consume resources. ”

"Before, Kong Ling was right, the reason why the True Demon Clan couldn't invade my Beidou with other methods was mainly due to some restrictions from the laws of heaven and earth, after all, in a sense, the Heavenly Dao is fair, and it will not allow some extremely unbalanced things to happen, which is the same as the Heavenly Tribulation. ”

"But among the heavens and all worlds, not everything is restricted by the laws of heaven and earth, such as some forbidden things. ”

"Back then, when the Ancient Demon Tribulation was in place, the True Demon Clan used the space stronghold to teleport people over and confront the monks of my Beidou Realm head-on, but in fact, these were just to confuse the public. ”

"Their real intention is to open up this spatial stronghold, which they built according to a forbidden formation, and it cost a great deal. ”

"Originally, this stronghold was going to be completely opened, but this news, which was extremely secret in the True Demon Realm, was still known by the people on the Holy Island through some channel. ”

"So there was that earth-shattering battle, and the result of that battle ended with my Beidou defeat, and all the strong people of the demon clan stationed here died. ”

"Later, things are simple, this Demon Cave was sealed by the powerhouses of the Holy Island, and they also used the countless spatial cracks in this Fallen Demon Valley to set up a large array, and the higher the cultivation level When people come to this Fallen Demon Valley, the spatial cracks will attack wildly. ”

"With the protection of the natural barrier of the Fallen Demon Valley, the demon clan did not dare to fight this idea easily, after all, the spatial crack in this place, even if it is an emperor-level powerhouse, it is difficult to deal with, and then the demon clan couldn't attack my Beidou for a long time, so they retreated back. ”

Li Chongtian explained with a wry smile.

"It turns out that this is the case, no wonder the Beidou Martial Empress came to lay down the Seven Star Lock Yuan Great Array, it must be to prevent the high-level of the demon clan from coming to fight the attention of this demon cave, after all, at that time, the spiritual veins of heaven and earth have all been destroyed, and there are fewer and fewer strong people in my Beidou. ”

"Then now that the spatial cracks in this Fallen Demon Valley are gone, does this mean that the demons are ready to attack this Demon Cave again?"

Li Mu suddenly thought of a bad guess, and he said with a solemn face.

"Yes, it is very likely that this is the case, otherwise it is impossible for the spatial rift here to suddenly disappear without a trace, this must be the true demon clan has found a way to stabilize this space. ”

"In addition, in this Demon Suppression Cave now, there is a true demon qi constantly overflowing, although it is only a small amount, but this is enough to prove that the seal is loose, otherwise it is impossible for the true demon qi to overflow. ”

Li Chongtian said with an ugly face.

"It seems that it is necessary to contact the Holy Island, if the demon clan really breaks the seal completely, then the consequences will be serious, by the way, father, how do you know this, seeing that you are so familiar with this place, could it be that you have been here before?"

Li Mu asked curiously.

"Yes, I did come here, I was chased and killed by the people of the Desperate Palace and the Ten Thousand Swords Gate, and finally I was forced to flee into this Fallen Demon Valley. ”

"Fortunately, my cultivation was not high at that time, the danger was not so great, and I also had the ancient divine sword of the Heavenly Sword. ”

"The Zhutian Sword is actually left behind by a holy island powerhouse who fought with the demons here back then, and there is still a weapon spirit in it, and it is precisely because of this opportunity that I have come all the way to this point. ”

"The Heavenly Sword Spirit is very familiar with this Fallen Demon Valley, when I came here under his leadership, I also saw this Demon Cave, and I also knew the ancient past from his mouth. ”

"By the way, that is, that time, I accidentally entered the Nameless Realm, and I also met your master Nameless. ”

When it comes to the past, Li Chongtian seems to remember it vividly, and his eyes show a look of memory.

"This is really a coincidence, no wonder my father rushed here as soon as he saw that all the spatial cracks in this Fallen Demon Valley had disappeared. ”

"Fortunately, you know this ancient secret, otherwise no one would have thought that in the depths of this Fallen Demon Valley, there would be such a demon suppression cave, so what should we do now?"

After Li Mu sighed, he got down to business.

"Things may be more serious than I thought, the powerhouses of the demon clan will soon come here and protect this demon cave so that they can break the seal. ”

"And with our current strength, there is no way to stop a large number of strong people of the Demon Clan from attacking, but there is no need to worry too much, to break this seal, it will take more than a dozen Demon Emperor powerhouses to attack at the same time. ”

"The Demon Clan is not short of Demon Emperors, but after they come, their cultivation will be greatly restricted, and at the same time, it is impossible for their combat power to remain at the emperor-level level, more than a dozen Demon Emperors, this is not something that can be gathered in a short period of time. ”

"Even if the demon clan has been planning for a long time, but it has only been so long since the Seven Star Lock Yuan Great Array was completely broken, even if those Demon Emperors came over as soon as the Great Array was broken, it would take at least two or three hundred years to completely dissolve the suppression of the power of the interface law. ”

Li Chongtian considered it very comprehensively, and he didn't show too much worry.

"The analysis is very good and logical, but have you ever considered another question, that is, the Protoss of the Heavenly God Domain. ”

"To be able to freeze such a chaotic space, except for the Protoss, I don't believe that the Demon Clan himself can do it, because if they could do it, they would have done it a long time ago, and there is no need to delay it until now. ”

"Also, since the True Demon Clan has fixed this space at this time, this means that they have absolute certainty to do it, otherwise no one would be stupid enough to expose their plan in advance, let alone such a big plan!"

Sun Qitian, who had never spoken, suddenly interjected, saying a question that made Li Chongtian, Li Mu and the others change their faces at the same time.

"What the dead monkey said makes sense, Li Daoyou, I don't think things are so simple!"

Xiao Tianlow obviously agreed with what Sun Qitian said, and he said with an ugly face.

"Someone, get out of here!!"

Suddenly, Sun Qitian seemed to have discovered something, two golden flames lit up in his eyes, he looked at the void on one side, and raised his hand and stabbed towards that space......
