After reading this letter, Wang Yuan couldn't calm the shock in his heart for a long time, and Xiaoying on the side didn't say a word.

"It seems that things are really not simple," Wang Yuan said......

"What are you going to do, Wang Yuan." Xiaoying looked at Wang Yuan and said. "Do you want to show this letter to Professor Zhou?"

"Fragments...... Will Professor Zhou also be a fragment...... "Wang Yuan said.

"But it's been sixteen years, but if he was also arranged by your parents, then I think he should contact you alone...... Xiaoying said.

"Don't show him yet." Wang Yuan thought for a while and said. "Xiaoying, only the two of us know about this matter, understand? Don't tell anyone. ”

"Well, can I join you in the search for clues?" Xiaoying said.

"Yes, you can."

Wang Yuan put the letter aside and turned his gaze to the other two things in the box, the other two things were a round cake-shaped stone, the surface of which was painted with a taiji, and some scratches like scales were carved around the circle. Another thing is a rectangular piece of cloth with some pencil drawings on it, the pattern is divided into two parts, the left and right parts are drawn, a vertical line is drawn in the middle as a dividing line, and the left half seems to be drawn as a dragon, but maybe the person who painted it is really not very good, this dragon is a little out of shape, and the dragon's body is also painted with something like thorns. The pattern on the right depicts an old man with a long beard.

"It seems that it is not possible to decipher these things ...... now," Wang Yuan said.

"What now?" Xiaoying asked.

"The people of the village can't trust anyone until they understand it thoroughly. It is very likely that Zhao Cripple was burned to death......" Wang Yuan said. "But I never understood the message he sent me, he said that there was something to give me, but I didn't go, he prompted me to go to the square lake, and what he was going to give me was really hidden there?"

"Your dad said he had a series of things for you, and you had only experienced this one before?" Xiaoying said.

"This is probably the only one, and the others are either I haven't noticed it yet? But this one thing alone seems to have been destroyed by others, and I only remember now that Zhao Cripple's frightened eyes at that time did not seem to be because of the arrival of Zhao Bin and Qi Zhuang, but because he noticed that there were other people around him who were monitoring his actions. Wang Yuan said.

"Did you think too much...... Xiaoying said.

"No, I think Professor Zhou's arrival may not be a coincidence, Xiaoying, do you think all this is normal? Before this, few people seemed to mention my parents, but this time Professor Zhou came, and it happened that at the same time, this box was also handed over to me by Grandpa Li, as if to remind me, let me give this box to Professor Zhou to see. Wang Yuan said.

"It's a bit of a coincidence that you say that." Xiaoying said.

"Xiaoying, you have a plan, I need you to do me a favor." Wang Yuan said.

Zhou An was a little embarrassed on Li Fangzheng's side at this time, because he really couldn't interject about the topic of Li Fangzheng, Liu Shiye and Li Zhiming and others, but he didn't want to leave, so he kept smirking with them, and after a while, he pretended to go to the toilet before leaving the room, and walked to the gate of the courtyard to find Wang Yuanzheng standing outside.

"Wang Yuan, didn't you go to Li Zhiming's father's house?" Zhou An asked.

"I've been there, and I'm back." Wang Yuan said. "Professor Zhou, when are you going to Yan Sheng Mountain?"

"Well, it's not decided yet, I want to know more about this village." Zhou An replied.

"By the way, can you tell me where those pictures come from?" Wang Yuan has been thinking about Zhou An's photos of strange symbols.

"You might be shocked when you tell the story of these photos." Zhou An said.

"Then scare me." Wang Yuan said with a smile.

Zhou An took out a box of cigarettes from his pocket, lit one and put it in his mouth, took a puff and said: "When I was more than seven years old, our country found the ruins of a village in the Spring and Autumn Period and the Warring States Period near Hemai Village. ”

"Hemai Village? It's not very close to our village. Wang Yuan said.

"Well, that site is very unique, their houses seem to be all made of wood, which is completely different from the dwellings of Qi or Lu at that time. I was also involved in the work at the time, and the most surprising thing for us was that the most of the work tools and household items that we unearthed in the entire site were not production tools or household items, but there were stones carved with large and small symbols, and five bones were excavated. When we drew down the symbols on the stones and studied them, we found that the symbols on the stones did not belong to any kind of writing known at that time, and even some resembled the hieroglyphics of ancient humans. With wooden buildings and pictograms, we thought we had found another civilization similar to the Hemudu period. Professor Zheng, one of the members of the team at that time, found that the arrangement of the symbols on some of the stones was somewhat similar to Zhou Yizhong's Bagua diagram, and he believed that these stones were used for divination, and because the location of the excavated stones was very messy, it was impossible to conduct further research, so we could only guess from these symbols. ”

"And then?" Wang Yuan asked.

"I've been working on the symbols with Professor Zheng since the initial excavation, but I haven't had a clue. Later, some measurement reports showed that the age of the village should roughly belong to the Spring and Autumn Period or the Warring States Period, just when we were a little confused, the age determination report of the five corpses excavated from the village came out, and the age of the five corpses was more than 100 years old...... You must know that in the Spring and Autumn Period, the average life expectancy of people was only more than 30 years old, and it is barely possible to say that there is a corpse bone that is 100 years old, but there are only five corpses in total, all of which are over 100 years old, which is absolutely impossible, and even once it was rumored among insiders that one of them may be as old as 200 years old. But then, we got the word that there was a mistake in the identification, and many of us were transferred to other places because of the need, and no one paid attention to it except me and Professor Zheng. Zhou An said.

"Two hundred years old...... Can humans really live to that age? Wang Yuan couldn't believe it.

"In the days that followed, out of curiosity, I worked with Professor Zheng while studying the symbols on the stones, but there was still no progress on my side, and over time I gradually let go of the matter, and I did not contact Professor Zheng for a long time. It wasn't until a few years later, when Professor Cheng died of a heart attack, that I went to his house, and his room was plastered with photographs of the kind of symbols we had studied, and what shocked me even more was that on the bookshelf directly above his desk, I found a thick notebook of his books, full of annotations on that symbol. I can't believe it, I have been rummaging through various classics for several years in order to study that kind of symbol, and I have always thought that it is impossible to connect them with so few symbols that I have obtained, but Professor Zheng Dan has made such a big breakthrough. When I looked at the notebook, my hands trembled a little, and I couldn't imagine the level of detail in the notebook, because it would have caused a great sensation in the archaeological community. So I offered Professor Zheng's family to take the notebook with me, and they agreed to give it to me, but only after the funeral. When I went to get it after the funeral, someone had stolen the notebook from the shelf. ”

"Didn't his family put it away?" Wang Yuan asked.

"I didn't think so, I thought that many people who were present on the day of the funeral had participated in our archaeological excavation, and that the purpose of stealing the notes was just to steal the publication of Professor Cheng's research results, but it seems that this is not the purpose of this day. What impressed me the most was that Professor Zheng wrote this sentence on the first page of the note: 'The ancient kingdom of the underworld, the unknown underground shrouded in witchcraft'. To this day, I seem to have no clue what I have in my possession, and since then I have been researching whether there was such a country or tribe in the land of Qilu during the Spring and Autumn Period and the Warring States Period in China. However, there are too few historical records of that period, and in the pre-Qin period, there may have been hundreds or thousands of countries on the land of China, which were called 'ten thousand states' at that time, so it is too difficult to find records about the kingdom of Hadeschi. Zhou An said.

"When is the pre-Qin period?" Wang Yuan didn't quite understand.

"It was the period before Qin Shi Huang unified the country, and that period of history should be the most splendid period of Chinese civilization, but with Qin Shi Huang's book burning and Confucianism, almost all the classics were burned, so most of the history we know about that period is brought out from the grave." Zhou An said.

"A hundred schools of thought contend, burning books and pit Confucianism......" Wang Yuan said in his mouth. With so many small countries, what's the use of finding the country of Hades? ”

"The more history the better, and I don't think the country of the Underworld is simple?" Zhou An said.

"Where can you see that?" Wang Yuan asked.

"It feels ......," Zhou An said.

"Aren't you going to take a look at that square lake?" Wang Yuan said.

"Actually, after listening to your description, I'm a little confused, if those stone carvings are really like the symbols in my photo, after two thousand years of lake immersion, the symbols on the surface of the stone should not have existed a long time ago, why are there still there?" Zhou An said.

"It seems that the river in the village has not existed since ancient times." Wang Yuan said.

"Huh?"

"The main source of water in that creek came from this river, and it is likely that the stone slabs carved with symbols before that were buried in the earth. Later, because of the opening of this river, it was washed out. Wang Yuan said. In this way, the purpose of digging the river is not just to get water. ”

"Wang Yuan, but judging from the conversation with you, you don't look like a teenager who is only sixteen years old." Zhou An said.

"Really? How can this be said, does the mental age do not correspond to the actual age? Wang Yuan smiled.

"I'll be here next Saturday, and you can take me to see the square lake then." Zhou An said.

"Are you leaving?"

"Well, I learned a lot today, but you don't want to talk about the photo I told you about and my entry into the mountain next week, understand?" Zhou An said.

"I understand."

"Take me to Mr. Li and tell them, and they will say that I will go first." After Zhou An finished speaking, he turned around and left.

"Should I trust you?" Wang Yuan looked at Zhou An's departing back and said.

At the same time, Xiaoying walked over from a distance and said to Wang Yuan, "Okay, let's go." ”

"Hmm." After speaking, the two walked towards the east of the village.

They were going to the old house that had burned down by Zhao Cripple.
