Not long after the meal, Zhai Ling was separated from the single book. Pen, fun, pavilion www. biquge。 info

Shan Ben wants to go to the research institute of the military department to continue to do the project, and Zhai Ling wants to go back to the academy to go to the Tianshu Tower to have a look.

For the Heavenly Book Tower, Zhai Ling has always maintained a great interest.

First, the Tianshu Tower is very famous, not only in Da Zhou, but even some surrounding countries are very concerned about the Tianshu Tower, and they all want to squeeze their heads into the Tianshu Tower to take a look, if it weren't for the strict control of the academy, let alone let people sneak in, maybe the entire Tianshu Tower could be robbed.

Second, the Tianshu Pagoda was built by the first dean of the Chenxu Academy, the ancestor of the South Building, and it was also his old man who wrote many peerless books. The meaning of this is by no means clear in one or two sentences.

And Zhai Ling's arrival this time was not only to go to the Tianshu Tower to find a book to read, but also to understand what conditions were required to enter the Tianshu Tower, which was not mentioned in the "Instructions for Learning and Traveling", which also made Zhai Ling a little depressed.

Before arriving at the Tianshu Tower, Zhai Ling's impression of the Tianshu Tower in his mind was not much different from the book towers on Ferris Island, and he guessed that it was almost three or five stories high, after all, those book towers on Skyscraper Island were also built during the period of the ancestor of the South Tower.

It was only when Zhai Ling really saw the Heavenly Book Pagoda with his own eyes that he realized how naïve his thoughts were.

"Hehe, little brother is here for the first time. A middle-aged guard leader on the side of the road took Zhai Ling's student ID and the dean's order, and smiled when he saw Zhai Ling's surprised expression.

"Yes, my first time. I didn't expect to be so far away, but I could still feel the magnificence of the Tianshu Tower. Zhai Ling was sincerely emotional, looking at the mountains a hundred meters away in the distance, the bronze appearance of the Tianshu Pagoda was vaguely revealed between the top of the mountain and the white clouds, even if it was so far away, he could still feel the majestic atmosphere of the Tianshu Pagoda, and he couldn't help but be stunned in his heart.

The middle-aged leader of the guards smiled and didn't speak again, and returned Zhai Ling's student ID card and dean's order to him, waving behind him to let him go.

Zhai Ling took these things, put them away, and left the checkpoint.

There are a total of twelve guards, each of whom is a cultivator at the fourth to sixth level of the foundation building period, and this is just a guard on the surface, Zhai Ling is also secretly amazed by the handwriting of the Dusty Courtyard under the cloth of the Heavenly Book Tower.

But he didn't think much about it, and went into the mountains.

The idea of building the Tianshu Tower in the mountains is really no one except the ancestor of the South Tower, but the ancestor of the South Building is the designer of the Tianshu Tower, and his idea was not vetoed even by the Emperor of the Great Zhou Dynasty at that time, so the Tianshu Tower has been standing in this mountain for hundreds of years.

Approaching the Tianshu Tower, Zhai Ling did not immediately enter, but stood aside and admired this ancient building that was more than 600 years old.

Although circular buildings can be seen everywhere in today's life, six hundred years ago, circular buildings were a big challenge in people's minds and in the craftsmanship of architecture, but the patriarch of Nanlou still insisted on his own views and built this circular building with his own characteristics.

The walls are made of marble or limestone into two shades of white bands, the arches of the half-exposed square columns, the carved doors in the arcades, the long diamond-shaped lattice flat roof, and the walls above the arcades form a strong contrast between the bright side and the shaded surface of the sunlight, which makes people feel a strong sense of solemnity very clearly.

"Amazing, isn't it?"

Suddenly, a hoarse voice sounded behind Zhai Ling.

Zhai Ling turned around and looked at an old man with a big blue and yellow gourd in his hand, wearing a slightly tattered Taoist uniform, the beard at the corner of his mouth was messy, and his eyes were cloudy but looking at Zhai Ling with a smile.

Zhai Ling shook his head, but he also recovered immediately, nodded and admitted, "It's amazing." Presumably, the patriarch of the South Building was also built against public opinion. ”

"Yes, any vision has to go through a struggle before it finally takes shape. You're good, lad. The old man took two sips of the wine gourd, burped and grinned and looked at Zhai Ling, "I have a hunch...... We'll see you again. Haha......"

Zhai Ling didn't understand the old man's words, but his pupils suddenly shrank, and he watched the old man disappear without a trace from under his nose.

Zhai Ling immediately understood, he had met a master, and he was not a master comparable to the high-level of the foundation building period, very powerful.

Shaking his head, he secretly sighed at the inexplicable old man, and Zhai Ling stepped into the Heavenly Book Tower.

There were no books in the hall of the Heavenly Book Tower, except for an old man with glasses and gray hair sitting at a desk in a corner and resting with his eyes closed.

Zhai Ling looked at the empty hall suspiciously, and was surprised to find that this hall was much smaller than what the outside world saw, and what was even more amazing was ......

"These patterns...... There are quirks. A little...... Snake eyes...... Three...... Five...... Eight...... This is the sequence of gods. Zhai Ling lowered his head and looked at the ground that looked like painting liquid smeared indiscriminately, but he was surprised to find that the points gathered on the patterns on the ground were the sequences of gods that were famous in the cultivation world.

0，1，1，2，3，5，8，13...... From the second term, each term is equal to the sum of the first two terms, and the decimal part of the ratio of the former and the latter term also tends to 0.618 infinitely, which is called the golden ratio.

According to the notes of the Nanlou Patriarch, human cultivation is inextricably linked to the sequence of gods, but no one has been able to truly understand the meaning of Nanlou Patriarch's words.

Zhai Ling's brows furrowed even deeper, no one would paint some messy things on the ground for no reason, not to mention that this was built by the ancestor of the South Building back then, and these patterns were also left over from that year.

"Little one, don't waste your time on these spots. Hundreds of years of old fellows studying these numbers have died one after another, and no one has ever known the secret behind it, do you think you can......? You better hurry up and read the precautions for entering the Tianshu Tower to read, don't waste your precious time. The old man in the western corner opened his eyes at some point, glanced at Zhai Ling and continued to close his eyes, and said slowly.

Hearing the old man's words, Zhai Ling looked at the patterns on the ground again, if it weren't for the sudden trembling of the space-time crystal in the dantian, Zhai Ling really wouldn't have calculated anything so carefully, but what the old man said was right.

So many powerful big people haven't studied the reason, and they can study it clearly at a glance, not to mention that the time to read books in the Tianshu Tower is limited, so it's better to put this matter back first, and there will be opportunities in the future.

"Thank you for the reminder. Zhai Ling hugged his fists and thanked the old man who had closed his eyes and recuperated.

The old man didn't say anything, he still closed his eyes and rested in a corner, Zhai Ling didn't mind, so he walked to the sign in the center of the hall according to the old man's previous reminder and looked at it carefully.

There are two whole pages, not much, but Zhai Ling looked at it very seriously, and couldn't help frowning.

"The Heavenly Book Tower actually has two hundred and thirty-three floors. Zhai Ling couldn't help but sigh in admiration.

It's just that Zhai Ling was a little surprised that the notice made it very clear that it didn't matter which floor the students went to, but it wasn't necessarily what area they would enter to read books.

What does this mean?

Could it be that there will be some formation that will teleport the students?

This is also the first time Zhai Ling has encountered such a situation, so he quickly took a closer look, but he was really right.

According to the idea of the patriarch of the South Building, the Tianshu Pagoda pays attention to chance, so a student with high chance will automatically be divided into a high-quality book area after entering any floor.

In other words, if Zhai Ling wants to watch some peerless books...... Unless other character outbreaks are assigned there.

"Whatever, let's go to the second floor first. With a decision, Zhai Ling walked into the cylinder elevator on the north side of the hall.

"Hey, little brother, wait, wait, wait for me. ”

Before Zhai Ling could close the elevator, a young man with a small head broke in outside the door, stretched out his hand to block the elevator, and the whole person looked at Zhai Ling with a smile and hurriedly rushed in.

"Brother came to read so early today...... That's right, there aren't many opportunities to go to the Heavenly Book Tower, so maybe you don't have to grab books with others if you come early. It was obviously not the first time he had come to Tianshu Tower, and he looked at Zhai Ling and said a lot of things.

Zhai Ling didn't answer a word, most of them listened to this person with a light smile, but when he heard what Ban Cuntou said about grabbing books, his brows shook slightly, but he didn't ask anything.

"Brother also went to the second floor, what a coincidence. Ban Cuntou also noticed the button next to the elevator and looked at Zhai Ling with a smile.

"yes. ”

As soon as Zhai Ling finished speaking, the elevator door opened, and the flood of white light suddenly emerged, Zhai Ling's vision was instantly obscured, and the voice of Ban Cuntou came from his ears, "Brother, I'm in." ”

Feeling that there was suddenly a lack of breath around him, Zhai Ling understood that Bancuntou walked in, and he was not ambiguous, and stepped in.

The white light flashed, and Zhai Ling's vision suddenly lit up.

As soon as you enter, you will see the house number marked "District 42".

"It seems that this is the 42nd district on the second floor, and I don't know if there are any books in it that I want to read. Zhai Ling's eyes were full of interest, and he looked at the dense bookshelves.

A total of one hundred and sixty-eight hours is enough for Zhai Ling to "squander".

......

Just when Zhai Ling entered the second floor of the Tianshu Tower, in the private courtyard behind the Tianshu Tower, the two old men were sitting together playing chess.

"I said Old Dengtou, have you really made up your mind?" an old man with a blue and yellow wine gourd pinned to his waist asked the white-robed fairy wind bone in front of him.

"This is the fate arranged by the patriarch of the South Building. The old man in white smiled faintly, and said that he was holding a black chess piece in one place, and he ate eight or nine pieces of the man at once.

"Damn! Old Deng, you are cheating, the director of your dignified and dusty courtyard is actually playing tricks on a wandering drunkard with me, damn, do you still want to be embarrassed?" The old man who claimed to be a drunkard was not happy when he saw that most of his son had been eaten, and insisted that the other party was cheating, and immediately stretched out his hand to push the chessboard without waiting for the other party to say anything.

"You scoundrel...... the dean chuckled and shook his head, not minding what the other man was doing.

"Hehe, I don't accept you to bite me...... Let's go, come back again, remember to take out your private collection of Jade Qiong Buddha fruit wine, we are so ripe, don't be so stingy. ”
