In addition to the treasures, gold and silver, there are three or four thousand books in this treasure pavilion, all of which are paper books, all of which are recent hundreds of years, mostly emperor's living records, etc., of course Bu An has no interest in this.

The dusty bamboo slips are all carved with small seals, and Bu'an is a little difficult to read, but even guessing with Meng, you can still roughly understand.

A total of more than 2,000 bamboo slips, most of which are well preserved, only a few dozen have been old and incomplete, Bu'an spent a few days, hastily flipped through it, but found nothing.

What is recorded on the bamboo slips seems to be the county chronicles of the Qin period, and there is nothing unusual about it.

After a few days, he felt that most of these well-preserved books were useless, so no one looked through them, so he focused all his attention on the dozens of volumes that had been mutilated.

The scope is reduced dozens of times, Bu'an looks carefully, and there are some gains, such as these bamboo slips, often appear "five elements", "yin and yang" and other words, one is even engraved with the word "Pangu".

However, these books are so badly broken that there are no ten words left, and they can't read at all, and even they can't guess what's missing.

When he looked through the broken bamboo slips, he was puzzled: they were also very dusty, and it seemed that no one had touched them for many years, just like the complete bamboo slips.

Bu An didn't have a clue for a while, thinking that his writing skills were not as profound as Tu Yao and Song Manqiu after all, so he invited the two of them into the Treasure Pavilion - but he hid the book with the word Pangu engraved in advance.

As soon as the two female Confucian students entered the library, they were like treasures, and they buried their heads in reading, but in the end, they were the same as Bu'an, and they didn't gain anything.

But Seventeen saw that the three of them hid together all day, isolating themselves alone, and became more and more resentful.

In a fit of rage, this crazy girl demolished a beautiful palace with her bare hands, and was still angry afterwards, and even lit the ruins with a fire.

At this time, Bu An, Tu Yao, and Song Manqiu were drilling in the Treasure Pavilion, and Sakura Beauty (Song Manqiu's nickname for the fake princess) ran in in a panic, saying that there was a fire outside.

The three of them hurried out and organized the palace maid to put out the fire. Fortunately, within this palace, the distance between the palaces was quite large, and the fire could not spread at all, so it was easily extinguished.

Bu An saw that Seventeen had always stood by with a cold face, so he guessed that she did it, and he suppressed the anger in his heart at the moment, and he didn't have a seizure.

The little virgin doesn't understand a woman's mind, but Tu Yao and Song Manqiu have always been against Bu'an when they see Seventeen these days, but they guessed seven or eight points, but they are sensitive when they think of Seventeen's identity, so they can't say anything.

Bu'an Tie walked back to the Treasure Pavilion with a blushing face, and Song Manqiu followed behind him, intending to explain, so he smiled and quipped: "The seventeenth girl is just playful." If she really makes it bad, she only needs to order this treasure pavilion, and she can burn books and pit Confucianism......"

This treasure pavilion is full of bamboo slips, and Bu'an, Tu Yao and Song Manqiu are all Confucian students, and this allusion is also very vivid.

Bu An shook his head with a wry smile, and then frowned: "Could it be that these bamboo slips have already been scattered in the Three Kingdoms of Water and Sky, and these are just a part of it?"

When Tu Yao heard this, he asked Ying Meiren to find a few elderly palace maids to come over. After that, several palace maids who came over said that they never knew that there were books hidden in this treasure pavilion, and of course they didn't know if this bamboo slip was left behind.

In the afternoon of the same day, Bu An simply walked out of the Treasure Pavilion and sat under the cherry blossom trees in the palace with Tu Yao, Song Manqiu, and Ying Meiren to drink tea.

The beautiful scenery in front of him, the refreshing tea in the cup, Bu An couldn't help but sigh, if this is the case, if Qingshan is also there, it seems that he doesn't need to go to great lengths to break this peach blossom source array.

It's been a month and a half since he's been in the battle, and he doesn't know what's going on outside. Qingshan must be in a hurry, although he told her that no matter what happens, there is no need to panic, but according to her temperament, how can she be calm.

As soon as he thought of this, Bu An thought that before leaving, he would find some treasures to take out to her in this palace treasure house.

If only among these ancient books there was Qin Shiyi's "Book of Music", which was once one of the six classics of Confucianism, and must have been extremely beneficial to her practice.

Bu An's mind moved, and he felt that the Three Kingdoms of Water and Heaven had existed since Qin, and maybe the "Book of Music" had never escaped here, so he asked about the cherry blossoms.

Sakura replied that she had never heard of the Book of Music.

Bu An knew that this beauty was famous for her piano music, and even she didn't know it, so naturally she wouldn't have it, so she was a little disappointed at the moment, and was about to pick up the teacup, when she suddenly frowned, a thought rose in her heart, and she stood up unconsciously.

Tu Yao and Song Manqiu looked at each other with puzzled expressions.

"The First Emperor burned books and pit Confucianism, why did he send so many books into the Peach Blossom Garden?" asked Bu An.

The two girls naturally couldn't figure it out, so they had to shake their heads silently.

"He left this place of refuge, did he ever think that if the descendants can't get out, what's the use of it?" Bu An asked again: "With the character of the first emperor, is he willing to watch his descendants live in seclusion?"

"Are you saying that he must have left a way to get out?" Tu Yao wondered.

"After the First Emperor burned books and pit Confucianism, there was a classic that disappeared from then on......" Bu An muttered.

Of course, Song Manqiu knew that what he was talking about was one of the Six Classics, but he couldn't guess why Bu An suddenly sighed, and he was puzzled: "But in that pile of books, there is no Music Sutra." ”

"What if the way out of the formation is in that pile of books...... Bu An tilted his head and said: "What if the real purpose of the First Emperor to burn books and pit Confucianism is to destroy the Book of Music?"

"You mean, that pile of books seems to be disorganized and has no clues, because the clues are hidden in the "Book of Music" that has been dispersed?" Tu Yao exclaimed.

It seems that only in this way can we explain why a tyrant who burns books and pits Confucianism will leave this pile of books for future generations. Bu An nodded and said: "In this way, he burned the "Book of Music", and he killed the grave digger in the pit, which is the same thing." ”

In fact, Bu'an has a faint feeling in the face of the pile of books these days, as if he is facing a pile of ciphertexts, and the reason why he has found nothing is because there is no secret key.

Perhaps the First Emperor had planned to use a widely circulated classic as a code book. It's just that the more he lives, the more cautious he becomes, and the older he gets, the more suspicious he becomes, so in the name of burning books and pit Confucianism, he removed the code book from the world, and left a lone book in the harem for the descendants of the Ying family to study.

Later, this lone book probably fell into the hands of the overlord of Western Chu who broke Xianyang City...... Yu Ji is good at singing and dancing, will the overlord give her this lonely book?

Bu An had a trace of luck, and suddenly whispered: "Okay, hide it again, aren't you afraid that I will throw you here?"

“...... To tell you the truth, the last "Book of Music" did fall into my hands, and I read it very well at the time, but I definitely can't recite it now, it's been so long. The voice of the female ghost that had not been seen for a long time sounded in his ears.

"You don't have to be able to memorize it. A glimmer of hope rose in Bu An: "If you see it again, will you recognize it?"

“...... You can give it a try. Yu Ji replied lazily.

Bu An smiled slightly, turned around and ran in the direction of the Treasure Pavilion, Tu Yao and Song Manqiu glanced at each other and followed.
