When the door of the Heavenly Book Pavilion opened, a bright golden light reflected from the main hall.

Ji Tianxing was stunned for a moment, turned his head and looked at the sky above his head and the sea of clouds around him.

It was shrouded in clouds and mist on all sides, not too dark, but not bright either.

On the contrary, in the main hall of the Heavenly Book Pavilion, there was a bright golden light, which looked brilliant.

Ji Tianxing had some doubts in his heart, stepped into the main hall, and looked at the situation in the hall.

The main hall is very wide and bright, with a radius of 100 meters, and the walls around it are inlaid with precious stone lamps, shining with a dark golden light.

The floor paved with dark white jade is carved with delicate and ornate patterns, presenting a magnificent picture of the stars.

In the middle of the main hall is a wide passage, and dozens of bookshelves are neatly placed on both sides.

Those bookshelves are like magic weapons, with special materials, engraved formations, and exuding invisible power.

Each bookshelf is ten feet long, and dozens to hundreds of books are placed on it.

The situation is just as Ji Tianxing guessed, this Heavenly Book Pavilion is a library building.

He wandered among the many bookshelves, looked closely for a moment, and found the clue.

The floor of the main hall and dozens of bookshelves are all clean and clean.

This made him frown, and muttered to himself: "Strange, there is a space hidden in the tombstone, and there is a mysterious Heavenly Book Pavilion.

This place has been at least a thousand years old, and how is it that it is still brand new and clean? There is not even a trace of the vicissitudes of time?"

He vaguely felt that there was something strange about this Heavenly Book Pavilion.

But since he had entered the Heavenly Book Pavilion, it was impossible for him to leave just now, of course, he had to figure out what was going on.

He wandered among the shelves, his eyes searching the shelves, scanning the rows of books.

Half an hour later, he looked at more than twenty bookshelves and swept through tens of thousands of books.

Without exception, these books are all biographies of historical books, recording all kinds of wild history secrets and biographies of celebrities.

Most of the books are titles similar to "The Legend of the Great Sword Emperor", "Cangwu Experience", "Kunyue Mountain Travels" and "Ten Thousand Years of Memorabilia".

However, the legendary people and places described in these historical biographies, as well as various cultural features, are unheard of by Ji Tianxing.

He even suspected that the powerhouses and places recorded in these biographies were not on the Tianxuan Continent.

Moreover, each bookshelf is protected by a mysterious formation seal.

That kind of formation power can protect the book from the erosion of time.

Ji Tianxing tried several times, but he couldn't crack the sealing formation on the bookshelf at all, and naturally he couldn't see the content in the book.

Half an hour later, he found a bookshelf in the corner of the main hall.

Presumably, the books stored on this bookshelf are not particularly important and precious, so the level of the sealing formation is low.

It took Ji Tianxing a day to crack the sealing formation of the bookshelf.

He rummaged through the bookshelves for a while, and found a book related to the Tianxuan Continent, called "Ancient Heavenly Mystery Volume".

In this thick ancient book, various major events and legends and deeds that occurred in the Tianxuan Continent in ancient times are recorded.

This is exactly the information he wanted to see, so he took the ancient book and carefully flipped through it, looking at its contents page by page.

After about an hour, he finally finished reading the ancient book.

For the Tianxuan Continent in the ancient era, he also had a corresponding understanding, and learned many myths, legends and ancient secrets.

According to the book, at the beginning of the ancient era, the Tianxuan Continent was still in the era of ignorance.

At that time, the five continents of this world coexisted, very far away from each other, but they had not yet been sealed by the gods.

At that time, there were thousands of races living together on the Tianxuan Continent.

Humanity is not the master of the continent, and is still in an era of large-scale kingdom building and frequent wars for food, minerals, and territory.

At that time, martial arts cultivation was in its infancy, and mortals could only cultivate to the Tianyuan Realm at most, and they had already reached their limit.

The powerhouses of the Tian Yuan Realm can dominate many kingdoms and form a super empire, occupying two or three percent of the territory of the human race.

Later, many gods descended from the sky and came to this continent.

Many gods and goddesses sheltered all ethnic groups, taught martial arts to all ethnic groups, and taught them the methods of cultivation.

Since then, all the clans in the world have gradually mastered the method of cultivation, learned to communicate with the aura of heaven and earth, and used various cultivation resources to continuously improve their own strength.

Martial arts have entered a stage of rapid development, martial arts geniuses of various ethnic groups have emerged in an endless stream, and martial arts powerhouses have also sprung up like mushrooms after a rain.

The human race has also gradually moved away from the stage of the kingdom ruling the world, and powerful sects and family forces have continued to emerge to override the kingdom.

Although, there will also be some contradictions and frictions between various ethnic groups.

But under the leadership of the gods, the people of all ethnic groups can always find a way to live in peace and multiply together.

Although the human race is inherently weak, it is the weaker existence among all the races in the world.

But the wisdom of the human race is outstanding, and the ability to learn and comprehend is very strong.

After thousands of years of multiplication, the Terrans have gradually become one of the major races on the continent.

After many years, the human race, the demon race and the water race have become the three most powerful races on the continent, laying a three-legged pattern.

At that time, the Tianxuan Continent was the most glorious and magnificent era of martial arts.

There are not only hundreds of millions of living beings who practice martial arts, but also gods who control the continent and shelter all races to recuperate.

But the good times didn't last long, and it didn't take long for a small battle of the gods to break out.

The power of the war of the gods shattered the barriers of the world and knocked the heavens into a loophole.

At the other end of the loophole, there is a connection to another world.

In that world, there is a very powerful and strange race.

The people of that race were born with infinite strength, and their physical strength, defense, and speed far surpassed that of any race in the Tianxuan Continent.

Moreover, they are very proficient in the art of fighting and fighting, and they can also devour the obscure evil qi between heaven and earth, suck the flesh and soul of living beings, and quickly increase their own strength.

There is no doubt that this powerful and evil race is the Demon Race!

It was a strange world, with scarce resources and a dilapidated state.

The demons obviously did not want to stay in that ruined world, and under the leadership of the Ancestor Demon God, they passed through the loopholes of the sky one after another, and frantically poured into the more vast and resourceful Tianxuan Continent.

As a result, the disaster of the Tianxuan Continent befell him.

After countless demons poured into the Tianxuan Continent, they frantically invaded the territories of various races and grabbed the properties and resources of all races.

They wantonly slaughtered the creatures of all races, devoured the flesh and soul of the creatures, cultivated evil secret methods, and quickly increased their strength.

Trillions of demons covered the Tianxuan Continent like a black tide.

All ethnic groups were slaughtered and enslaved, and they were in dire straits.

The gods who sheltered the various races also angrily fought back to resist the invasion and slaughter of the demons.
