An Yu slowly walked up the steps again. All the walls, stairs, handrails, steps, and even bookshelf here emitted a faint glow, making the library full of soft light, which was very natural and comfortable. If An Yu had not observed carefully, he would not have even discovered the existence of a dispersed light source.

"Ah?" An Yufang walked to the second floor underground and suddenly became confused: "Why is no one coming for such a large library?" He looked up and down again, and it turned out that he was the only one in the huge space.

Back on the first floor of the underground, An Yu casually read a few books and found that they were all architectural, such as southern houses, palace regulations, wooden beam construction, etc. Under the great wonder, An Yu changed several bookshelfs to see, and they were still architectural works, such as An Yu holding a book at this time.

An Yu laughed silently and shook his head slightly. No matter what, he didn't expect that the entire floor of the library would be filled with architectural-related books. So An Yu came to the second floor. He was full of expectations and imagined a possible situation: "It's not music, right? Well... it shouldn't!"

When he picked up a book that looked quite old, An Yu's face became awkward in an instant, and he read it word by word: "Seven! Strings! Piano! Made... It's really a musical instrument!" After putting down the first book, An Yu took a few more books, including nine-strings zither, bamboo flute, horn, etc., which are numerous.

An Yu saw from the beginning and end on the second floor. Sure enough, it was all about music books, including music theory, music score, the manufacturing and playing methods of various musical instruments, etc., and everything was included in categories.

"Interesting! The layers below are not all of these books, no wonder no one came here, so that's it!" An Yu said intimately.

The third layer is history, politics, family and other classics, not only from Milei, but also from many other countries. The fourth layer is geographical, and there are relevant information on the region, culture, and even climate change on the Yadekot continent.

The fifth and sixth floors are the biography of historical celebrities, emperors, generals, doctors, and all famous people are included. An Yu read it one by one, and he was dazzled. After reading it, he could not remember anything in a blink of an eye.

After rubbing his eyes, An Yu sighed helplessly and said to himself: "The library of Yushan School, even if it is a lay disciple, there should not be no booklets about martial arts! The seventh floor and the last floor must be martial arts!"

An Yu put all his last expectations on this last floor and slowly walked down the steps. An Yu walked to the nearest bookshelf, picked up the booklet, and was immediately disappointed because the name of the book was!

"Damn! No!" An Yu became dejected. He flipped through the books one by one, including farming in seasons, animal husbandry and fishing bans, and even works on astronomical calendars, festivals and solar terms, but there was no secret to the martial arts.

"Haha, it seems that I'm overthinking it. There is indeed a reason why no one comes to a place!"

An Yu sighed and went to flip books one by one. Although he had no expectation in his heart, he had already turned it over here. If he didn't finish it, he would always feel a little regretful or uneasy. This may be the willfulness and persistence of the perfectionist...

Most of the books here are covered with fine dust. I think the disciples of Wushu come in to read it, and even the managers of the library are too lazy to clean the place.

"Cough!" An Yu finally walked to the last row of bookshelfs. In the corner, the dust became thicker, and even the handwriting on the cover was blurred. An Yu gently whipped it, and the dust flew, causing him to cough a few times. After he recovered, he saw the words on the book, "Theory of Herbal Cultivation"!

"Hey, these managers are too irresponsible. They are lazy on weekdays and even the basic cleaning work is only done on the third floor." An Yu murmured to himself: "I'll be a volunteer!"

There were naturally cloth and clear water in An Yu's Hunyuan Pan. He wet a piece of cloth and wiped it on the dusty bookshelf, and immediately cleared up a line! He naturally would not let go of every book, wipe it clean one by one.

An Yu couldn't help but recall that when he was a child, he did the same thing in the study room of the An family compound. Although he was asked to do such chores in his name, he could not practice and wander in the magnificent and strange world of books, and temporarily forget the unhappiness in reality. It was also his unique happiness when he was young!

"Time is so fast, and things in the world are unpredictable! I have become the head of the An family for no reason now, and I have also come to the Yushan Sect and become a lay disciple of the Yushan Sect..." An Yu put down a clean book, feeling very moved, but he did not notice the four big words "Secret Method Volume 1" on the book!

After wetting a piece of cloth again, An Yu carefully wiped a few books, but he did not notice the name of the books, "Secret Method Volume 2", "Secret Method Volume 3", etc., all passed by his hands and put them back in their original place.

"Huh--I finally finished wiping a bookshelves!" An Yu sighed and turned to the opposite bookshelf: "Print another one today! Please wipe the rest when you have time."

Thinking that there was only one bookshelve left to wipe, An Yu was immediately full of energy and moved in a hurry. From top to bottom, from left to right, both inside and outside, and the booklets, they became spotless and even shining.

"Ha! Perfect!" An Yu said proudly, and at the same time, he slapped the rag lightly. He heard a "pop" sound, but he accidentally hit the bookshelf behind him with the rag and bounced one of the books to the ground.

An Yu stuck out his tongue and slowly turned to Luoshu. His happy mood was slightly reduced because it was a little imperfect.

The book on the ground was still buckled, An Yu snapped his fingers, gently lifted it, and then stuffed it back directly to the original place, and quickly went to the outsider.

Fang walked to the upward stairs, and An Yu suddenly stood there, because two words suddenly flashed out of his mind, secret method!

"Secret Method?" An Yu asked suspiciously: "Secret Method? The book just now seemed to have the words "Secret Method" written? Is it? Herbal secret method or alchemy secret method?"

After hesitating for a while, An Yu finally decided to go back and take a look. The last bookshelf, the last few books, were clean on them, which were exactly the traces that An Yu had wiped.
Chapter completed!
