There is an ancient country in the Bohai Sea, its name is Zhen, divided into five capitals and ruled it, and the rise and fall of the history of the Shan Ya.

In fact, Chen Ziyang still knows a little about the ancient Bohai country, which is divided into five capitals, fifteen prefectures, and sixty-two prefectures. Among them, Xijing Yalu Mansion is today's Linhai City, Jilin Province.

Especially after the collapse of the ancient kingdom of Bohai, part of the remnants of the ancient kingdom of Bohai split out and established the ancient kingdom of Ding'an, the capital of which was located in Linhai City, Yalu Province. The ancient kingdom of Bohai was destroyed by Liao, and the ancient kingdom of Anding in the later period became the center of resistance to Liao, but Chen Ziyang's understanding of the ancient kingdom of Bohai was limited to this.

Chen Ziyang and Yang Lei went back and forth between the librarian and the seats, constantly changing books one by one. After half a day's work, the two of them looked at one head and two big heads, and they had a headache.

But fortunately, reading books at this time does not require rote memorization and memorization of all the knowledge as when you were in school, but only needs to understand the relevant knowledge. And two people are also more interested in these things, people are like this, they often remember the things they are interested in more firmly, and they remember them more quickly.

But even so, until the library was about to close in the evening, the two of them had only read a few dozen books combined. They each borrowed a few books, and the two of them went to a fast-food restaurant next to the library, where they continued to read while eating. At this time, a man sat beside them with a plate.

"It seems that the two of you seem to be very interested in the ancient country of Bohai, I don't know what kind of books you are looking for about the country of Bohai, I can give you some introduction." The man sat down next to Chen Ziyang and then said to him.

Hearing this person's words, Chen Ziyang raised his head and looked at him, only to see that the person in front of him was as thin as a hemp rod, wearing a pair of glasses like a thick glass bottle bottom, which was very similar to Qin Liang's original pair of glasses, and it was also a scholar's demeanor, but this person was very young, looking only in his twenties.

"Oh? Do you know a lot about the ancient country of the Bohai Sea? Don't know who you are? As soon as he heard that someone could help him, Chen Ziyang had a hint of luck and wanted to hear what he had to say, which was better than a blind cat like himself touching a dead mouse and looking for a mess.

"I don't know anything, I just like to read, I'm the intern administrator of this library, you have been looking for materials about the ancient country of Bohai this afternoon, and you are even reading it when you are eating, it seems that you are very anxious, see if there is anything I can help you."

It's best not to read books when eating, so it's easy to get dirty with books, and you don't waste time while eating, and I talk at the same time. After the man finished speaking, he bent the index finger of his right hand, and said with his knuckles to support the thick glasses on his face.

Listening to his words, Chen Ziyang judged two things, first, this person likes books very much, otherwise he would not advise strangers not to read books when eating, for fear of staining books. Second, this person should really be well-read, not because of the thick glasses on his face, but because of his spirit of cherishing books.

This is really a noble person who went out, and I didn't expect such a living treasure to come out of thin air, so Chen Ziyang closed the book in his hand, and also closed the book in front of Yang Lei, nodded at this person and said, "I want to hear it." We really don't know anything about the ancient country of Bohai, can you pick up the key points and tell us about them first. ”

"The ancient country of Bohai is the regime established by the Tatar people during the Tang Dynasty, the founder is the leader of the Tatar tribe, Da Zuorong, the original name of the ancient country of Bohai is Zhen, which is also a very interesting place in this country, this country is the only country with the name of the hexagram in the gossip.

There are many theories about this earthquake word, and even about which earthquake word is this earthquake, there are at least three kinds of controversy, the writing of the vibration word is different, and the meaning of this shock word is different. However, I am more convinced to say that the leader of the Yan Dynasty, Da Zuorong, was familiar with the history of the Chinese language and was deeply influenced by the culture of the Central Plains, because the Bohai Kingdom was located in the east, so he named the country after the hexagram of Zhou Yizhen. ”

"Oh?" Hearing this, Chen Ziyang raised his eyebrows, and he couldn't imagine that the history of the ancient country of Bohai, which he first ignored, contained such a hidden and important clue.

If a country really uses the hexagram of gossip as the name of the country, then it is enough to prove that the country will have a lot of applications for gossip in all aspects. Since ancient times, the development of metaphysics has been based on gossip, and countless changes have been derived.

At that time, Zhuge Liang used stones to form a gossip array, blocking hundreds of thousands of soldiers from outside the array, making the gossip array famous for a while. Some time ago, Chen Ziyang used the Quanyang Array in Li Zhuo's tomb, another name is also called the Bayang Array, which is based on the hexagram position of the Bagua as part of the base of the array.

With such an important clue, dealing with the various mechanisms in the underground palace will have a direction, so as not to be blinded.

I didn't expect this person in front of me to help so much. Chen Ziyang hurriedly asked Yang Lei to add a few dishes, and asked for a few bottles of wine at the same time. This made this little four-eyed embarrassed, and several people talked while drinking, and they talked happily.

At the time of separation, Chen Ziyang knew that Xiao Siyan would go to work in the library tomorrow, so he made an appointment with him to help introduce some key books the next day, and Xiao Siyan also agreed.

That night, neither Wang Chuan nor Umbrella Shishuai came back, probably busy with their respective affairs. Chen Ziyang and Yang Lei finished reading a few borrowed books, and fell asleep. The next day, before the library opened, the two of them rushed there early, waiting for the arrival of Little Four-eyed.

For a whole day, with the help of Xiao Siyan, the two of them systematically learned some knowledge about the architectural style, architectural structure, architectural techniques and various casting processes of the ancient Bohai Kingdom.

Because he was afraid that the little four eyes would find out that they were going to rob the tomb, he didn't let him introduce books about tombs, in fact, there were very few books on this subject. After thanking Little Four-Eyed for their kindness, the two of them borrowed a few books and left there.

The harvest of this day with the help of Xiao Siyan'er is greater than the time for two people to watch it for a few days, the most important thing is that there is no waste of time, at this time Chen Ziyang is in a good mood, after going to the hospital to see Wang Lele in the evening, he feels that even God is helping them now.

In the evening, Wang Chuan and Umbrella Shishuai also returned, and several people exchanged ideas with each other about the progress of the day, and then waited for the arrival of the pattern on the gold disc the next day.
