"It's unfortunate that a day has passed so quickly." The young man scolded and walked out, without even looking at Ning Wutian, and returned the token to the disciple guarding the door when he went out.

And the disciples at the gate were not surprised, obviously this kind of thing had already been seen for a long time.

"Space teleportation? This tower doesn't seem to be as simple as it seems. ”

Ning Wutian was secretly surprised, and then continued to walk inside.

Instead of entering the dense bookshelves as I imagined, I saw a silver portal, like a light portal formed by energy.

The light gate echoed the token in his hand.

"No wonder you need a pass." Ning Wutian was stunned.

There is also a staircase next to it, which is supposed to lead to the second floor.

"Let's take a look at the first layer first."

Ning Wutian walked towards the light gate in front of him, his body touched the light gate, and suddenly the token in his hand sent out a stream of energy to envelop him, allowing him to easily enter the light gate.

After entering the Light Gate, that energy did not dissipate, and Ning Wutian had a feeling that if he didn't have the protection of this energy, he would probably be attacked by the formation here.

"It seems that the purpose of the pass is to prevent someone from sneaking in and stealing." Ning Wutian knew it in his heart.

Looking around, Ning Wutian was stunned for a moment.

This is a space tens of thousands of meters long and wide, and the dense bookshelves in the space are neatly arranged, and each bookshelf is full of books.

At a glance, there are dense books, and a quaint atmosphere comes to the face, with a burst of decay.

"How can there be so many?"

Ning Wutian was dumbfounded.

I'm afraid that there are more than 100 million books here, and this number is too terrifying, if you read them one by one, I'm afraid that you may not be able to read them in thousands of years.

From the outside, the tower is only twenty meters long and wide, and thirty or forty meters high, and the space inside is unbelievable.

"Maybe it's the means of the Almighty, it should be the so-called formation space." Ning Wutian thought so.

Technological means can also achieve such an effect, or even better, Qing'er can do it, and even create a simulated living environment.

Therefore, Ning Wutian was only surprised, but he was not like Grandma Liu.

Ning Wutian suddenly regretted that he didn't bring Qing'er with him, if Qing'er was here, he would scan it directly, it would be faster than anything else.

But fortunately, there are various classifications, and Ning Wutian searched according to the classification.

Humanities, geography, species, history, formation knowledge, alchemy knowledge, the difference between monks and mortals......

The various classifications dazzled Ning Wutian.

When I was looking for a book, I could occasionally see one or two people who came here to read.

"If you look for it like this, you don't know when you're going to find it." Ning Wutian was speechless.

Suddenly, Ning Wutian saw an old man sweeping the floor with a broom in a corner hundreds of meters away.

Ning Wutian's eyes lit up, this old man should be very familiar with the Library Pavilion, maybe he could provide useful information.

So Ning Wutian hurriedly walked over.

This old man is too old, shriveled and thin, his face is wrinkled, and he is about to die, and it seems that he will lose his breath at any moment.

Such an old man would come here to sweep the floor?

"Excuse me, old man." Ning Wutian said politely, he didn't look down on this old man because he was too old.

Those who can sweep the floor here are at least a monk, and you must know that you have to charge money just to enter here, and to be able to sweep the floor here means that you can read the books here at will.

This sweeping old man may not be very strong, but it is estimated that his status is not low.

The sweeping old man slowly raised his head and glanced at Ning Wutian, his eyes were cloudy and full of vicissitudes.

Then he lowered his head again and continued to sweep the floor, but there was no dust on the ground, but he swept it very seriously.

Ning Wutian smiled and said, "The junior wants to find a book about special talents, please tell the old man the location?" ”

"The third floor, the Immortal Gu Secret History Area." The old man who swept the floor replied without raising his head.

Ning Wutian's eyes lit up: "Thank you, old man." ”

got the answer he wanted, Ning Wutian bowed, turned around and was about to leave, but suddenly saw the old body of the sweeping old man who was about to die, and his heart moved.

Flipping his hand, he took out a small bottle: "This is something I got by accident, maybe it will be useful for the elderly." ”

Ning Wutian put the small bottle into the hand of the sweeping old man, and then turned to leave.

The old man who swept the floor didn't care at all, what a Lifespring monk took out couldn't have any effect on a monk of his realm.

However, the moment he saw the crystal clear liquid in the transparent vial, emitting a faint blue-gold light, the old body shook suddenly.

"It's ...... The Immortal Fountain in the Ancient Forbidden Land! ”

The sweeping man's originally cloudy eyes radiated a terrifying gleam.

What was surprising was that he actually knew this Immortal Holy Spring.

……

What Ning Wutian gave to the sweeping old man was the lake of life obtained in the center of the Ancient Forbidden Land, which was called the holy spring of immortality to outsiders, and had the effect of extending life.

That's just one or two bottles filled with genetic stock solution, and if it is used well, it shouldn't be a problem to help sweep the elderly live for ten years.

At this time, Ning Wutian came to the second floor, where there was also a light gate.

However, Ning Wutian did not enter this light gate, he walked directly to the third floor.

As expected, there was also a light door on the third floor, and Ning Wutian walked in directly.

The space on the third floor is much smaller, only about a kilometer away, and the number of books is much smaller than that on the first floor.

Although there is still no intensive exercise here, the things recorded in the books on the third floor must be many times more precious than those on the first floor.

I thought there should be a lot of people here, but in fact it was very quiet.

Come to think of it, even the ticket is a thousand amethyst coins, and not everyone can enter.

A thousand amethyst coins are probably the entire net worth of most people, and many people will not be willing to read a book just for a day.

According to the classification, Ning Wutian quickly found the Immortal Gu Secret History area.

"The origin of the Immortal Ancient Battlefield?"

"The system of the Immortal Gu Monks."

"Speculation on the Restoration of the Immortal Ancient Environment......"

The books in this area turned out to be about the Immortal Gu Period, and some of the titles of the books shocked Ning Wutian's heart.

However, at this time, what Ning Wutian wanted to read most was books about special talents, and he really wanted to know about the so-called special talents immediately.

"Huh? Got it! ”

Suddenly, Ning Wutian was overjoyed and looked at a yellowed book on the books.

There are a few big words on the cover of the book: Introduction to Special Talents.

Although it was only an introduction, it also made Ning Wutian very happy, and hurriedly picked up the book.

I don't know if it's an illusion, Ning Wutian felt that the book seemed to be closely related to this tower, and if he forcibly took the book away, he would likely be attacked.

"The means of the Almighty, it is incredible." Ning Wutian exclaimed, and then began to flip through the books in his hand.
