After some thought to no avail, Li Mu immediately came up with the idea of other jade slips on the bookshelf. With the Dream ()

Picking up a piece of jade slip that looked simple and abnormal, Li Mu once again spread out his spiritual sense and probed.

After a while, Li Mu's face showed a look of disappointment, what was recorded in this second jade slip was also an exercise, and it was far from a level exercise like the Hongmeng Purple Sutra, it was just an ordinary heaven-level exercise.

Just casually glanced at the beginning of the exercises described in the jade slip, and then Li Mu withdrew his spiritual sense, and then he picked up the third jade slip and began to investigate.

It took a full hour to investigate the third jade slip Li Mu.

What was recorded in this third jade slip was finally no longer a technique, but a formation, a formation called the Seven Star Town Heavenly Array.

This formation is extremely mysterious, although it is not clearly mentioned what grade of formation it is.

However, Li Mu found that it was extremely difficult to arrange this seven-star sky-shaking array by watching the whole formation.

In terms of the difficulty of its formation, this Seven Star Heaven-Shaking Array was more difficult than all the formation arrangements in Li Mu and the Water Emperor Eclipse Baichuan's memory, and it was more than a star and a half difficult.

In order to arrange this array, the person who arranges the formation not only needs to have a high level of attainment in the formation, but also needs to fit the interface rules of the time and place and the entire interface.

The general formation is to use the formation material combined with the rune formation pattern, and no matter how much it is, it is nothing more than to match some formation flags to enhance the power of the formation.

This is not the case with this Seven Star Earthquake Array, if you want to arrange it, you first need to build a complete interface as the foundation.

Secondly, it is not enough to have a formation platform, it is also necessary to gather the power of the interface law of the realm to enter the formation, and it will take millions of time to accumulate the power of the interface law, and this seven-star heaven-shaking array can be completed, and the difficulty of its formation can be imagined.

Among the formations that Li Mu knew, even if it was the immortal array and some forbidden formations that refined the Heavenly Spirit Treasure, it was far less difficult than the Seven Star Heaven-shaking Array, after all, just arranging the formation based on the entire interface was far from being comparable to ordinary formations.

Among the formations that Li Mu had seen with his own eyes, just in terms of the ability to penetrate the heavens and the earth, as well as the great influence of the formation, the forbidden formation in the True Demon Realm and the seven-star lock element arranged by the Beidou Martial Emperor back then could be called the best.

Among them, the forbidden formation arranged by the True Demon Realm can not only absorb a large amount of true demon qi from the True Demon Realm, but also penetrate the restrictions of the Beidou interface law, and descend on the Beidou through the Demon Suppression Cave, and the rebellion of this formation can be imagined.

As for the Seven Star Lock Yuan Great Array, the main function of this formation is defense, in order to prevent outside cultivators, especially the True Demon Clan, from invading Beidou, the Beidou Martial Emperor used the entire Beidou's underground Yuan Vein as the benchmark, and arranged the anti-heaven formation.

Whether it was arranging the forbidden formation of the True Demon Clan, or the Seven-Star Lock Yuan Great Array, they all paid an unimaginable price.

The forbidden formation of the True Demon Realm consumed a lot of materials and time cherished by the Thirty-six Royal Clans and the Five Great Emperor Clans.

And the Seven Star Lock Yuan Great Array locked Beidou's Yuan Vein, causing Beidou's Heaven and Earth Yuan Qi to become thinner and thinner, and this kind of price is not something that an individual can bear.

However, in comparison, this Seven-Star Heaven-Shaking Array, both in terms of the difficulty of the formation and the cost it required, was far superior to the Seven-Star Locking Yuan Great Array and the Forbidden Formation of the True Demon Realm.

After all, it takes millions of years to accumulate a formation, and the formation can be completed, even ordinary emperor-level figures cannot have such a long lifespan.

What made Li Mu feel the most strange was that although this jade slip recorded the method of arranging the formation of the Seven Star Earthquake Array, it did not say the specific existence and function of this array, and it did not even explain whether it was a defensive or offensive formation, or an auxiliary type of formation.

"The Seven Star Earthquake Array and the Seven Star Lock Yuan Great Array are both named after the Seven Stars, so there is no connection between the two."

"Also, this level of formation, it is not an exaggeration to describe it as earth-shattering, the key is that it is impossible for ordinary people to arrange it, even if it is arranged according to the method of this formation, there is absolutely no one under the true immortal who can successfully arrange it, after all, the formation can only be completed in millions of years, and even the ordinary true immortal cannot afford it. ”

"The most important thing is that there is no record of the specific use of this Seven Star Heaven Shaking Array, why did such a jade slip stay here, could it be that someone did it on purpose?"

Li Mu fell into deep thought again.

On the ninth floor of this scripture building, those who are not cultivators above the emperor level are not allowed to enter, on the contrary, as long as the cultivation reaches the emperor level, there is no restriction and they can enter at will.

This means that the emperor-level powerhouses who have been to the Holy Island before and have entered this scripture building must have all come to the ninth floor of this scripture building.

In addition, if there is no accident, the formation method of the Hongmeng Purple Sutra and the Seven Star Earthquake Heaven Array, those who have entered this ninth layer must have also seen it.

"Isn't it bad, if that's the case, it's not good!"

Li Mu thought about it and suddenly thought of a not very good guess, he was in a hurry, and hurriedly took out the Holy Island Island Master Token, and then sent a message to Chen Changsheng.

This Holy Island Island Master Token has many functions, in addition to being able to control many formations and prohibitions on the Holy Island, it can also contact the elders of the Holy Island, of course, the premise is within a certain range.

Not long after Li Mu's summons came out, Chen Changsheng's reply was quickly sent back, and after learning of Chen Changsheng's reply, Li Mu's eyes suddenly lit up with two gleams.

"Sure enough, it seems that the secret of my Beidou realm is not small!"

Muttering softly, Li Mu's face became even more gloomy.

He summoned Chen Changsheng and asked one thing, that is, on the ninth floor of this Hidden Scripture Pavilion, there are records of who have been here.

And Chen Changsheng's response was that all the emperor-level powerhouses from the Beidou Realm had basically come to visit the Holy Island, and they had all been to the ninth floor of this scripture building.

Although the Holy Island is nominally the number one force in the Beidou, the number of emperor-level powerhouses produced by the Holy Island is very limited, and there are not many emperor-level powerhouses on the seven continents of the Beidou.

Under the innate condition of the Seven Star Locking Yuan Great Array to lock the Heaven and Earth Yuan Qi, anyone in the Beidou Cultivation Realm who is an emperor-level powerhouse is basically an invincible existence in the First Realm.

And in the face of the emperor-level powerhouse, the holy island does not want to have a bad relationship with them, basically they are all friends, or pull them into the holy island, and this scripture building because of the countless treasured classics, naturally it will inevitably attract the attention of those emperor-level figures, so all the emperor-level powerhouses from the Beidou realm have basically come to the ninth floor of this scripture building.

"Not far from ten, this matter is already very clear, but all the emperor-level powerhouses from my Beidou have basically come to the ninth layer of this holy island, that is to say, they have all seen this Hongmeng Purple Sutra, and they have also seen the content recorded in these jade slips. ”

"Dozens of emperor-level powerhouses, each of them have different life experiences and experiences, the only thing in common is that they have all been to the Holy Island, they have all entered the ninth floor of this scripture building, and the final result is that they all disappeared inexplicably. ”

"Absolutely, it can't be wrong, it seems that their disappearance should have something to do with this place, but what is the reason for it, and what is the key?"

Li Mu figured out the general direction of the matter, but he was still puzzled as to how the Beidou powerhouses disappeared.

After thinking about it, Li Mu sent a message to Chen Changsheng again, the thing he asked was whether the three emperor-level powerhouses of the Thunder Emperor, the Buddha Venerable, and the Flame Venerable had ever been to the Holy Island and the ninth floor of this Tibetan Scripture Building.

This time, Chen Changsheng only replied to Li Mu after an interval of nearly a stick of incense, obviously because the time was too long, and he also needed to check it to determine what Li Mu asked.

Chen Changsheng's reply to the message was indeed as Li Mu expected, among the three Thunder Emperors, except for the Venerable Shakya, the other two had never come to this holy island, even the Venerable Shakya who came to the holy island, had never come to this scripture building.

From this, Li Mu can 100% conclude that the disappearance of the powerhouses of the Beidou dynasties is related to this scripture building, and it must be related to this ninth floor.

"In addition to the statue of this Hongmeng Daoist, there are only these bookshelves and some jade slips here, it seems that if the secret is not in this statue, then it is in these jade slips!"

Li Mu took a deep breath, and in the next three days, he looked at all the jade slips.

After reading all the jade slips, Li Mu had three big heads.

The value of these jade slips is indeed not small, including the alchemy method of immortal-level elixir, and there are also some powerful exotic treasure refining methods, as well as some powerful ancient talisman refining methods, which can be said to be all-encompassing, and all aspects are involved.

But if you say that the most valuable thing is the method of arranging the Hongmeng Purple Sutra and the Seven Star Earthquake Array.

Although the Hongmeng Purple Scripture is jerky and difficult to understand, and the Seven Star Earthquake Array is not at all human power to arrange, in terms of value, the content recorded in other jade slips on this bookshelf still cannot be compared with it.

Of course, this is not to say that the other jade slips are worthless.

The content described in these jade slips is also of great value to ordinary emperor-level figures.

Some of them are even emperor-level figures, but for Li Mu, they seem a little chicken.

"Hongmeng Purple Sutra and Seven Star Earthquake Heaven Array, if I am an ordinary emperor-level person, after coming here, I will definitely write down all the contents of all the jade slips here, although the jade slips cannot be brought out of this scripture building, but there is no harm in writing them down. ”

"Especially this Hongmeng Purple Sutra, this is an immortal-level top-level exercise, even if it is jerky and difficult to understand, after writing it down, I will try my best to crack the cultivation, after all, this is a shortcut that can help people become immortals, it is much stronger than the heaven-level top-level exercises. ”

Li Mu thought about it carefully, and he felt that the disappearance of the Beidou powerhouses was very likely to be related to the Hongmeng Purple Sutra.

After all, the Seven Star Earthquake Array is just a method of arranging a formation, and it is not a formation that ordinary people can arrange at all.

But this Hongmeng Purple Sutra is a practice, although it is jerky and difficult to understand, but if you spend some time pondering, ordinary emperor-level powerhouses can still try to cultivate.

Because many emperor-level powerhouses who disappeared suddenly disappeared in retreat.

Li Mu thought about it carefully, those emperor-level powerhouses retreated to comprehend the Hongmeng Purple Sutra, which was also possible, and the possibility was not small.

Although he had this idea, Li Mu was not 100% sure, he turned his head to look at the statue of Hongmeng Daoist not far away.

In the entire hall, except for the jade slip and the bookshelf, only this statue remained.

Although he had already carefully probed the statue with his divine sense, Li Mu was still not at ease, and he approached closer.

This statue of Hongmeng Daoist is only three zhang high, and it looks constantly lifelike, and it is also cast with a relatively rare kind of pure gold, Xuanji Yuan gold.

Xuanji Yuan Gold is an extreme metallic material that can be used to refine imperial weapons, and it is an unavoidable refining material in the cultivation world.

If he saw it somewhere else, with such a large piece of Xuanji Yuan Gold casting a statue, Li Mu would definitely feel incredible, but in this Holy Island Scripture Pavilion, he felt very normal.

After all, the accumulation of resources on the Holy Island is not comparable to that of ordinary sect forces.

Tsai carefully looked at the statue of Hongmeng Daoist for a few times, and finally Li Mu shifted his gaze to the purple beads held by Hongmeng Daoren.

On that day, in the Treasure Pavilion of the Holy Island Treasure Vault, the Northern Darkness was shocked by the fact that the treasure space was opened from the purple beads in the hands of the Hongmeng Dao people.

Thinking of this, Li Mu felt that this purple bead might have something else mysterious
