However, at this time, Bu'an encountered a second hurdle: many of the more than 2,000 words were repeated.

Obviously, there must be many repetitive words in the more than 2,000 words at the beginning of the Book of Music, but in this way, it is difficult to sit down in the order of the book.

Bu'an fell into deep thought again.

First of all, the Tibetan head text composed of more than 2,000 books does not match the number of words in the original text of the "Book of Music". In other words, it may have other rules besides being a Tibetan head.

In fact, why is the sixth character hidden in the "Book of Music"? Does the number six have any special significance to the first emperor?

This question came to mind the answer at once. The Seven Heroes of the Warring States Period, the First Emperor destroyed the Six Kingdoms to dominate the world, which was the greatest achievement of his life.

Bu An then thought that in addition to the sixth character, the other places in this pile of books must also hide the rest of the "Book of Music", and these places should also be related to the life deeds of the first emperor.

After he reminded her, Yu Ji immediately listed the thirteenth character of all the scriptures - the reason was naturally because the first emperor Yingzheng ascended the throne at the age of thirteen.

Sure enough, as the two of them expected, the thirteenth character of the book also contains the original text of the "Book of Music", which is just after the previous more than 2,000 words.

With reference to the two sides, the original situation of not being able to determine the order of the words due to repetition was immediately resolved.

On the eleventh day of this work, Bu'an sorted out the order of more than 2,000 books, as a by-product, according to this order, the sixth, thirteenth, thirty-ninth and forty-second characters of the books happened to be the full text of the long-lost "Book of Music".

At the age of thirteen, he became the king, destroyed the six kingdoms, became the emperor at the age of thirty-nine, and sent Xu Fu to the overseas immortal mountain at the age of forty-two...... These four numbers are really important to the First Emperor.

According to Yu Ji's memory, the first emperor burned books at the age of forty-four to pit Confucianism, which also corroborates Bu'an's guess from another angle:

That is, the first emperor first sent these ciphers that could be deciphered by the "Book of Music" into the Shui Tianze Kingdom, and then destroyed the surviving "Book of Music" by burning books and pit Confucianism - it is likely that after two years, he became more cautious and suspicious.

After determining the order of the book, Bu An got a "Letter to Future Generations" with a length of more than 2,000 words.

This long article is hidden more deeply, and it is composed of the first simple first word, the second simple second word...... The last word of the 362nd Jane, and the last second character of the 363rd Jane...... Such a zigzag palindromic order.

In addition to a large number of reprimands for the unfilial descendants of later generations, the text also recorded a very secret legend - since it came from the mouth of the first emperor, Bu An felt that even if this legend was bizarre, it was most likely true.

The First Emperor said that the world of Shenzhou has existed for 10,000 years, and the rotation of life and death has its own fixed number, and it is the Nuwa clan that makes up for the lack of heaven and hinders the reincarnation of the soul between the ten thousand worlds, so that the people in the Shenzhou realm are becoming more and more prosperous.

Nuwa's move was naturally to gain more believers and gather boundless trust, but she never imagined that the reincarnation of the soul was blocked and accumulated in the Shenzhou realm, which unexpectedly created a prosperous world for cultivators.

The implication of the First Emperor's words seems to be that if the Qin Dynasty is destroyed in the hands of cultivators in the later generations, he can borrow the hands of the Nuwa clan in the East China Sea to open up vacancies in the heavens, so that the spiritual energy of this realm will be exhausted.

In fact, this statement, Bu An also heard the monk Huiyuan talk about it at the earliest, that is, the so-called "there is a hole in the sky, and it can't be mended", and when Qin died, the first queen made this secret public, but Hu Hai's generation was too incompetent and had no ability to use this secret to turn the tables.

Bu An felt that since the First Emperor had hidden the capital of the reversal here, he would inevitably leave a way to get out of the battle at the same time.

Only then did he set his sights on the dozens of other books that had been mutilated—they were too bizarrely missing, most of them were already incomplete when they were sent to this realm, and the mystery of how to make up for them was probably hidden in the more than 2,000 complete books that had been straightened out.

Bu An then buried his head in the meantime, looking for a way to crack it, but for several days, he found nothing.

Yu Ji suggested that maybe Tu Yao and Song Manqiu would have a way, because they both had deeper writing skills, or they could turn to Zhang Blind and the others for help, because they were good at the five elements of yin and yang.

After much consideration, Bu An vetoed the proposal.

If there is a method for freely entering and exiting the water Tianze Kingdom hidden in this book, the less people know about it, the better.

The middle realm of this realm is too precious, but the troops can also hide the wealth, the advance can be attacked and retreated, and the entrance is located in the Xiongcheng Jiangning, for the hegemony of Bu'an, the role is immeasurable.

As a last resort, he didn't even want Tu Yao and Song Manqiu to share this secret.

And the people in the Seven Divisions, except for Zhang Blind and Hui Yuan, almost all of them are formation cultivators, if they peek through the mystery of this Peach Blossom Source Array one step in advance, it is difficult to guarantee that Bu'an will not be able to temporarily rise up and monopolize this world.

For the world of Shenzhou, this water Tianze country is naturally inconspicuous, but if there is a chance to enjoy this world exclusively, and even in the future, how many people can resist the temptation?

Bu An didn't want to take risks, or he didn't want to test such a big temptation to test the people of the Seven Divisions.

Therefore, he closed the door of the Treasure Pavilion tightly, kept trying and making mistakes, and almost didn't think about it.

On this day, Yu Ji saw the sword on Bu'an's waist and asked him to borrow it.

This sword is the one sent by Emperor Fengwu, Bu An has been immersed in the stacks of books, almost forgetting about it, and when he heard the words, he drew the sword and handed it to her.

Yu Ji was slightly disappointed and said: "The shape is like a Tai'a sword, but unfortunately it's not ......"

Bu An had never easily obtained anything good except for Su Su since he crossed over, so he had long been accustomed to this feeling, and smiled and inserted the ancient sword back into the scabbard.

"The scabbard is not bad, thick and black......" Yu Ji glanced at Bu'an's waist and smiled.

Bu An rolled his eyes, and said in his heart that this female ghost didn't know whether to see the scabbard or something beside it. These days, Yu Ji has made a lot of efforts, and it is not easy to reprimand her, so she leaned on the bookshelf and casually talked about the ancient sword.

Yu Ji is well-informed, claiming to have seen Mrs. Xu's sword with her own eyes, and said that Jing Ke's cultivation is not high, otherwise she would not be able to kill the King of Qin with a treasure weapon in her hand, and said that Mrs. Xu's cultivation is very high, and she is stable and surpasses the little Taoist priest.

Bu An sighed with emotion: "Sure enough, you can't underestimate the female streamers." ”

Yu Ji froze when she heard this, and then laughed: "Mrs. Xu...... Ha ha...... Mrs. Xu's surname is Xu ...... A lady, a good man...... Hahaha...... How did it get into your mouth, and you became a woman......"

Bu An was embarrassed for a while, and then opened the topic and asked Yu Ji what kind of sword the first emperor used when Jing Ke stabbed Qin with a fish intestine sword.

"The sword ...... in your back," Yu Ji replied with a smile.

Bu An nodded slowly, and suddenly a thought flashed through his mind, and he hurriedly turned over the bamboo slip in front of him.

It was at this time that Tu Yao opened the door and came in, telling him that Situ Yan had proclaimed himself emperor in the Qi State and sent an envoy to persuade him to surrender.
