On the wall of the thirty-first hall, a small door suddenly appeared, the size of which was only large enough for one person to enter at a time.

"Sure enough, there is still a chance that has not been discovered, go in and have a look. ”

The little turtle was excited, and took the lead in flashing into the secret room, and soon the others followed.

This is a darkroom, but about twenty square meters, a table, a bookshelf, there are a lot of ancient books, I don't know how long no one has been here, it is covered with a thick layer of ash.

The green lantern is lonely, illuminating the four directions, and the wall drawings of the four divine beasts are engraved on the four walls, which are lifelike and vivid.

The green dragon takes off, the white tiger covers the ground, the vermilion bird spreads its wings, and the Xuanwu Hengpan... These are the four legendary guardian beasts, guarding the four universes and eight wildernesses.

Then, they first walked to the bookshelf and blew away the dust, and there was a row of ancient books of all kinds, with all kinds of books on them.

Mu Chen picked up an ancient book, it was very thick and the texture was also good, surrounded by the atmosphere of time, and I don't know how many dynasties this book has gone through.

"Ancient characters..."He opened the ancient book, and the font inside was actually ancient characters from the ancient period, which was difficult to decipher.

"The Age of Mythology... It's hard to get by... Seven Immortals... Dead..."

What do you mean?

Mu Chen frowned, and struggled to distinguish a few words, which was still very incomplete, after all, this kind of writing was too ancient, even if a scholar who professionally cracked the ancient characters could not come, and many cultures in the past had been completely buried.

Immediately, he turned another page, frowned, and struggled to decipher the ancient words: "There are women... Sad... A sea... One Night Blue..."

A few words are still recognized between each paragraph, and it is difficult to understand the original meaning of the original text in the record.

"This should be a wild history, or a record of myths and legends. He secretly guessed that because the Seven Immortals were originally a myth, it was impossible for seven Earth Immortals to appear in an era, and each life could only become one person, so people were more willing to believe that this was just a legend, a false myth.

Then, he put the ancient book away, and when he found someone to decipher the original text, he turned to look at the other books.

The ancient books included in this secret room are really miscellaneous, Mu Chen has read several books before and after, there are sermons, cultivating sentiments, and even weapon scores and chess scores, there are many types, but there is not a single technique left.

After a while, he lost interest and walked around here, while Luo Siyuan was fascinated by an ancient Buddhist scripture, and Luo Guangling was holding a Taoist notebook to figure out...

"Hey, Brother Turtle, you..."

Mu Chen was surprised, and saw the little turtle standing alone in front of the wall engraved with the Xuanwu diagram, his eyes were confused, and he didn't move any of them, as if he was in a fixed position.

Is there something strange about these carvings?

He secretly guessed, walked forward quickly, walked to the little turtle's side, and after making sure that it was okay, he also looked at the Xuanwu diagram.

On the wall, a huge green turtle Hengpan earth, the turtle shell is engraved with chessboard-like lines, as if the top can top the blue sky, the bottom can shake the nine shadows, the depiction is very vivid, just like to come to life.

However, apart from feeling the domineering divine might of Xuanwu in the picture, he didn't find anything else, so he walked in front of the other carvings.

All beasts surrendered, and with a roar, the mountains collapsed.

The Vermilion Bird spreads its wings and strikes tens of thousands of miles, which can kill gods and demons and protect the common people.

This should be the earliest four divine beasts, born in the early days of heaven and earth, each one is strong to the extreme, Shenwei I, the master of the ups and downs of the ancient period.

Each of them guards the world, which can be described as immeasurable merit, so it will always be remembered.

Finally, he came to the Qinglong map, observed carefully, experienced the supreme majesty, and respected it.

At this moment, the dark night on the back of the wood dust glowed on its own, shooting out a trace of black light, and hit the green dragon in the picture fiercely.

A dragon chant came out, waking everyone up, only to see a divine light in the eyes of the green dragon on the wall, and pieces of cyan dragon scales were stretched and still swimming.

"It's alive!"

Mu Chen exclaimed, the carved picture in front of him actually moved, and a huge coercion surged down like a mountain, making everyone feel that the blood circulation was not smooth.

Whoosh, in the next second, the green dragon on the wall rushed out, turning into a blue light, which penetrated into Mu Chen's forehead with lightning speed, and then burst out with a burst of blue light, isolating him from everyone.

"Wood!"

"What's the situation? What did he do?"

Everyone was surprised, a green dragon suddenly appeared in the secret room, and they were still isolated, and they didn't know whether this sudden change was good or bad.

"Don't go over, the wooden boy is fine, and there may be a great opportunity. ”

The little turtle widened his eyes, stopped Luo Siyuan and the others who wanted to rush over, looked envious, and said: "Damn, why did everything happen to this kid, it's unreasonable, I just don't know what kind of inheritance he can get." ”

At this time, Mu Chen fell into a strange space, and his eyes were white, and he raised his head and suddenly showed a shocked look.

A green dragon with a length of thousands of miles hovered in mid-air, and the dragon's tail gently swayed, tearing apart the cracks in the space, and the breath like the pressure of the sky made people want to bow and worship.

"The first generation of green dragons!"

Mu Chen lost his voice, completely shocked, everything in front of him was like a dream, he could be sure that this was definitely the green dragon from the ancient period, otherwise why was it so powerful, just a trace of breath revealed at random made it difficult for him to resist.

Wait, no, as we all know, the first generation of divine beasts all died in ancient times, otherwise where did the divine beasts of the later generations come from, he stared at the air deadly, and suddenly realized, "This is not true, is it will?"

He muttered to himself that the dragon above his head was a little hazy and lifeless if he looked closely, so he was sure that it wasn't an entity.

"What year is it?"

Suddenly, the green dragon looked at Mu Chen, and the invincible aura became even greater, and it spat out people's words, if the heavenly bell hammered, the head of Mu Chen's head was buzzing.

Mu Chen, at this time he was confused again, this dragon was able to speak, and his body was becoming more and more condensed, and his body was handsome and domineering.

"This is a new era, a journey through the past, through mythology, through the ages, millions of years from your time. Mu Chen saluted and replied to Qinglong cautiously.

"Millions of years," the dragon muttered to himself, and the huge dragon head lifted up, looked into the distance, fell into deep thought, and after a moment of silence, it said, "Is it here?

"Are there immortals in this world, and how many sages are there?" Qinglong spoke again, looking at Mu Chen.

"There are no immortals in the world, not even saints, the strongest person in the world is the emperor. Mu Chen replied seriously.

"What! There is not even a saint, what's the matter, a big world, vast and unprovoked, with thousands of races and billions of living beings, there is still not a saint?" Qinglong said in shock, revealing a puzzled look.

"How is this possible..."

At this time, Mu Chen was even more shocked, and his heart set off a monstrous wave, vast and unbounded, hundreds of millions of living beings, how big should it be, you must know how big the spiritual world is today, and the living beings are only ten billion...

He shuddered, and a thought came to him.

Could it be that there is still an unknown time in the past?

And the sky has changed!
