Passing through that white portal, Tuoba Aoyu entered the most mysterious third floor of the Great Dao Sect Library.

As far as the eye can see, there are layers of black bookshelves, and the black bookshelves are forged from some kind of material, exuding a cold atmosphere.

The space inside the third layer is very large, at a glance, it is impossible to see the end, many books are quietly placed on the shelves, Tuoba Aoyu scanned it inside and out with his pulse sense, and found that there are at least more than 10,000 books on the third floor, and he was surprised in his heart, the foundation of the Great Dao Sect is really profound!

Thinking of his first priority, he immediately began to flip through the shelves.

The first book Tuoba Aoyu read was called Gonzo, which recorded many of the author's observations, many of which were things that Tuoba Aoyu had never seen and heard of.

If he had enough time, he would have to go through it carefully, but the three layers of authority he had were only one day, so he couldn't choose.

In an instant, his pulse spread, and he sped up his browsing.

Unconsciously, half a day has passed, and gradually, Tuoba Aoyu is a little anxious, so far, he has read almost half of the books, but the largest place recorded on the map is only within a radius of tens of thousands of miles from the Great Dao Sect.

In a hurry, Tuoba Aoyu's speed accelerated a lot again.

Finally, he found a book called "Travels to the East", the author of which was a Triple War Spirit Realm monk who had survived the Heavenly Thunder Tribulation and liked to explore everywhere, so he recorded his footprints.

Flipping through the pages of this book, gradually, Tuoba Aoyu's face became more and more unsightly, and even turned blue after reaching the worst.

"If I am not mistaken, the Northern Desert must be one of the Eight Wildernesses, and this book only records part of the eastern wilderness. But it is already the most detailed record in the map I have browsed so far, I originally wanted to find the map near the East Desert, and then, from it, to find the traces of the Northern Desert, so as to return to the Northern Desert, now it seems that I can only take one step at a time. Tuoba Aoyu's face was gloomy, secretly thinking about everything in front of him.

"It doesn't make sense to look at it any longer, the eastern barren capital is vast, and there is no cultivation of the Enlightenment Realm. It is impossible to go all over the Eastern Wilderness, but most of the monks who can cultivate to reach the realm of enlightenment are powerful people who retreat and cultivate, and few people deliberately record and measure the Eastern Wilderness, so what I want to do now is to recognize the main vein or the Cangmai Zhenmai Great Technique. ”

"The main vein has the Great Dao Technique, and the Cangmai has the Deification Technique, and you can only choose one of the two. I have the increase in the pattern of the hundred beasts, and the amount of physical strength is already extremely strong, and the power of the deification technique is limited no matter how much I cultivate, but it is the Great Dao technique. Since this technique is known as the first technique of the Great Dao Sect, it can increase the chance of breaking through the Passage Realm after breaking through the Triple Battle Spirit, so it naturally has its own reason, and it will be quite beneficial to my future cultivation. Tuoba's eyes flashed. His face was slightly softened, and he had a plan for this.

The Great Dao Technique is limited in the power it can show in the Battle Spirit Realm. But its greater effect is to increase the chance of the monk breaking through the Enlightenment Realm.

The War Spirit Realm, one layer of heaven, three layers of heaven.

Through the realm of knowledge, it is as difficult as the blue sky!

The Great Dao Technique is known as the Great Dao Sect Zhenzong Great Technique, which can increase the probability of breakthrough, which is extremely unheavenly, so Tuoba Aoyu weighs it a little, and has a choice in his heart.

The Great Dao Technique is different from other precious classics, it and the Deification Technique and the Spiritual Transformation Technique float quietly on the top of the pavilion, and there is a treasure light on it, and Tuoba Aoyu reaches out with his big hand and directly takes down the Great Dao Technique.

Then, began to sit cross-legged on the ground to memorize, the number of words in the Great Dao Technique is not much, but the words are beautiful, which contains the true meaning of the Supreme Dao, Tuoba Aoyu just memorized, and it took a lot of effort.

It seems that the Great Dao Technique is difficult to engrave in his mind, but fortunately, his qi and blood are vast enough, so there is no interruption in the middle, so that he can complete this technique in one go.

At this time, more than an hour had passed, and there was not much time left for Tuoba Aoyu, thinking that he had finally entered the library once, Tuoba Aoyu decided to take the opportunity to explore.

Pulse Jue glanced at the precious classics on the bookshelf in front of him, and suddenly, Tuoba Aoyu saw a dark black book with four large black characters written on it, "Heavenly Demon Ruins Miscellaneous!"

"Heavenly Demon Ruins Miscellaneous Talk!" Tuoba Aoyu's heart moved, where he seemed to have heard about the Heavenly Demon Ruins, but where it was, he couldn't remember it clearly.

"Where the hell is it?" Tuoba Aoyu frowned, but suddenly, a gleam flashed in his eyes, and he said secretly: "Yes, when I was in the Lion Tribe, when Alan's aunt Nangong Qianqian and the senior sisters in her sect were separated, they seemed to mention this Heavenly Demon Ruin.

Immediately, with a hint of curiosity, Tuoba Aoyu opened the Heavenly Demon Ruins in his hand and talked about it.

On the first page, there are rumors about the ruins of the Heavenly Demons.

"The ruins of the heavenly demons, the origin is unknown, it seems to have suddenly descended to the east and the wilderness, and it seems to have existed for a long time, specific, no one knows, because there are two words of the heavenly demons on the periphery of the ruins, so the monks call it 'the relics of the heavenly demons'. ”

"The ruins of the Heavenly Demons, only monks below the Passage Realm and above the Sky Realm can step into it, there are all kinds of treasures, brute weapons, pills, the Ancient Great Power Cave Mansion, the powerful inheritance of the Ancient Strongman, countless resources, how many treasures are inherited in it, no one can find out,. ”

......

After reading page by page, Tuoba Aoyu finally had a clear understanding of the Heavenly Demon Ruins in his heart.

The Heavenly Demon Ruins will be opened once every five years, and at that time, all the young heroes of the East Wilderness will participate in it to compete for the real King of the East Wilderness.

Next, Tuoba Aoyu watched several miscellaneous books one after another, and got a lot of information that he didn't know before, and benefited a lot.

Suddenly, there was a ripple, and the body that Tuoba Aoyu was looking at suddenly froze, and then disappeared.

Outside the Library Pavilion, Tuoba's Proud Yu body slowly appeared, he looked back at the Library Pavilion, turned around and turned into a long rainbow and left.

By going to the library on the third floor to look through the classics, Tuoba Aoyu learned that the Great Dao Sect had such a place to cultivate, and its name was 'Extreme Pavilion'.

The Extreme Pavilion, as the name suggests, takes the meaning of challenging the limits of monks, and only monks in the Battle Spirit Realm can step into it.

Because, the coercion in it is too strong, and the monks who step on the Skyclave Realm cannot step into it at all.

The Extreme Pavilion has three floors, corresponding to a heavy war spirit, a double war spirit, and a triple war spirit.

The first layer has five times the gravity, the second layer has ten times the gravity, and the third layer has twenty times the gravity.

If a monk who stepped into the Sky Realm stepped into it, whether it was a monk from the Ten Star Realm, the Twelve Star Realm, or even the Fifteen Star Realm, it would be difficult for them to withstand the pressure from it, and they would explode and die.

Even if it was a Great Dao Sect's Battle Spirit Realm cultivator, they would generally not enter it to cultivate, because a Heavy Battle Spirit Realm cultivator could only barely withstand its coercion within the first layer.

Moreover, most of the monks will come out after holding on to it for less than half an hour, even if it is the first time for a monk in the Double Battle Spirit Realm to enter the Extreme Pavilion, they do not dare to step directly into the second layer, and can only slowly adapt to the first layer before they can enter the second layer.

As for the Triple War Spirit, they can directly step into the third layer, but the coercion that the third layer can cause, many monks in the Triple Battle Spirit Realm are a little unbearable, and they will also come out after less than half an hour of entering.

This is the reason why the Extreme Pavilion of the Great Dao Sect is called the "Devil Pavilion" by many disciples of the Inner Sect. (To be continued......)
