The library of Jiuzhizong is located on a giant peak near the academy, because this giant peak is towering into the sky, it is enough to look down on the whole picture of the entire academy when standing on the peak.

The two of them stood on the giant peak where the library was located, Ye Xianglun watched from afar, the entire structure of the library was made of stone, and the corners of the building were edged with copper, the whole building was simple and unpretentious, like the mausoleum of the ancient emperors, and next to the library was a wooden hut, which was the place where the people who supervised the library lived.

Uncle Yu threw a bunch of keys to Ye Xianglun, and then explained Ye Xianglun's daily work and daily life, and then left Jufeng.

Before leaving Jufeng, Uncle Hao also specially instructed him that he only had the right to let Ye Xianglun stay in the library for one month, and after one month, the library management personnel must go through the normal entry procedures.

Ye Xianglun had already thought about it when he decided to stay in the Jiuzhi Sect, judging from the task assigned by the talkative kun, he was going to join a sect next, and because of his original "whimsy", the five tones were chaotic, since the Jiuzhi Sect, which had extravagant intercession, refused to include him, then other sects would probably reject him.

In his current situation, he can't stay in the Jiuzhi Sect for a long time, and then he has to face the pursuit of the class, so what he has to do at present is to quickly improve his strength, even if he can't improve his strength in a short time, he must find a solution to the problem of "five-tone chaos" that he is currently trapped in before leaving the Jiuzhi Sect.

After the idea was decided, Ye Xianglun began to target the library, hoping to find the answer he was looking for.

So, after Uncle Lu left, Ye Xianglun first opened the hut next to the study, took a brief tour, and found that the wooden house was fully furnished, then locked the wooden house and walked towards the library.

Walking to the door of the library, Ye Xianglun took out the key left by the uncle, picked out the largest key, and inserted it into the copper lock of the library. Ye Xianglun hurriedly took a few steps back, watching the stone gate slowly rise from the bottom to the top, until the stone gate completely stopped, Ye Xianglun walked into the library in a false alarm.

After entering the library, Ye Xianglun found that the already dim library had become bright inside after the stone door was fully opened.

Slowly moving along the wall of the library, Ye Xianglun found that the library was extremely cold, as if the air conditioner was turned on to the lowest room, the wall of the library, every few steps, there was a wall lamp, the light emitted by these wall lamps was not very bright, but the library was illuminated like day, Ye Xianglun was curious, and after lying in front of the wall lamp and watching carefully, he was surprised.

It turned out that the whole note element was placed in the wall lamp, and you must know that the whole note element is the most valuable source of energy for the whole note pianist, and for the whole note violinist, it is as important as the soul, but I didn't expect it to be placed in the library for lighting.

Shocked, Ye Xianglun continued to observe, and after his arm accidentally touched the wall of the library, he found that there were countless water droplets on the stone wall, and after the water droplets gradually became larger, they slowly flowed down the wall and fell into the dark groove under the wall.

Ye Xianglun followed the direction of the water flow of the dark trough and walked forward, and found that there was a small hole in the middle of each wall in the trough, and the water flow of the dark trough would flow out of the library through the small hole.

After thinking about it, Ye Xianglun understood the truth: it turned out that this was for the purpose of moisture-proof in the library, after the humid air in the library met the cold wall, after the humid air was cold, it would become water droplets adsorbed on the wall, and with the increase of water droplets, it would slowly merge into the dark groove under the wall and flow out of the library, so as to avoid the humid air in the room from making the books moldy or deformed.

After briefly familiarizing himself with the environment, Ye Xianglun began to look for the books he needed under the light of the wall lamp.

The books in the library are divided into three areas: left, middle and right, and Ye Xianglun rummaged through the leftmost area.

"The History of the Southeastern Countries?

"The History of the Scrolls of the Sects?

""Preparation for the Disciples of the Nine Peaks Sect?

......

......

""Guqin Famous Songs General Examination"?

"The General History of Musical Notes?

"Wait, maybe you can take a look at these books!"

Ye Xianglun searched from the leftmost book area to the last row of bookshelves in the middle book area, and finally stopped, deciding to start with "General History of Music Notes". Because he really knows very little about the elements of musical notes, if he wants to solve his own problems, he must start from the most basic things, so Ye Xianglun stopped in this area, starting from the first book at the top of the bookshelf.

The books of "General History of Music Notes" occupy a total of more than two rows of bookshelves, if you count them one by one, there will always be thousands of these books, if Ye Xianglun wants to read carefully, I am afraid it will take two or three years, and now the time left for him is not so sufficient, so he must learn all the knowledge he needs to know as quickly as possible.

After briefly flipping through the first volume of the book, I found that this volume mainly explains the origin and formation history of musical elements, and Ye Xianglun has basically understood this knowledge from the book "Element Control" when he was in General Cai's mansion, so Ye Xianglun quickly flipped through the past, and after turning dozens of volumes in a row, the content of the book is still about similar knowledge.

Ye Xianglun began to skip some volumes, and directly flipped through the books on the next shelf, until he turned to more than 100 volumes, and finally found the word whole note in the content of the book. So he picked up the scroll and patiently looked at the whole note.

Ye Xianglun reads books more purposefully, basically ten lines at a glance, when he retrieves useful information, he will stop and read carefully, time always passes quickly in the hands of people who have something to do, Ye Xianglun is reading hungryly, the sky has darkened.

"Dinner is coming, sir, please dine!"

The call outside the door made Ye Xianglun interrupt from the sea of books, and then he thought of Uncle Luxury's parting explanation, and hurriedly walked out of the library to go out to receive food.

The food delivery staff outside the door was an ordinary-looking old man, about fifty years old, judging from his dress, he didn't look like a disciple in the sect, Ye Xianglun took the meal, said a few simple greetings, and sent the old man down the mountain.

When going down the mountain, Ye Xianglun paid special attention to it, and found that the old man came on a suspended reef, and Lao She was carrying two lunch boxes behind him.

After taking the meal, Ye Xianglun walked towards the wooden house with the unfinished book, lit the light in the room, and continued to read the book while eating. It wasn't until the book was finished that he picked up a few thick books from the library and prepared to read them at night.
