At first, I still pretended to be graceful, smiling and listening to Ruoyu. But as I listened, the smile on my face stiffened. Because I know the information that Ruoyu said, I also have a copy of the same information on my computer.

Ruoyu said, "I saw a person named Yan Yan in this information. At first, I was not sure, so I called the person in Beijing to ask for confirmation. At this time, the person in Beijing had already found Yan Yan's tomb and bones on the grassland, and brought them back to Beijing for testing to confirm the time of his death, which was basically the same as the year of Yan Yan's death engraved on the tombstone. And he made a reconstruction of the skull. After getting Yan Yan's date of birth that I had confirmed, the person in Beijing used the ID number I provided to find out the photo on Yan Yan's ID card through the relevant departments. After restoration image comparison and genetic analysis, it was determined that the skeleton was Yan Yan. ”

Ruoyu looked at me with blazing eyes, "The travel group spontaneously formed by the travelers in that information is the destination of Lop Nur. In this list, there is a person, you know who it is! ”

I smiled wryly and said, "I know, the person you're talking about is me." Yes, I do have me on this list. Soon after the list was confirmed, we went to Lop Nur together. ”

Ruoyu said, "After seeing this list, plus Yan Yan's matter, I have an idea in my heart. So I surveyed everyone on the list. But after investigating, I was a little puzzled. Because almost all the people who participated in this tour group, after going to Lop Nur, there was no more news. You're the only one who came back safely. ”

I said, "You don't doubt that I killed them all, do you?" ”

Ruoyu said, "That's not true, at least Yan Yan's matter can also prove it." I just want to know what the hell is going on in Lop Nur? ”

I said, "Let's not digress for now, I'll tell you about Lop Nur later." You'd better move on to your business first, right? ”

Ruoyu nodded and said, "Okay! Later, I went to work in a research institute at a university in the United States, where I was engaged in research on Chinese history and culture. There, the legend of Bogda was discovered. At first, we thought that this Bogda was the Bogda mountain range in Xinjiang today, but some information gathered showed that our thinking was very wrong. The legend of Bogda exists only in some tribes of the Mongols. But research shows that there is no mountain range in the Mongolian steppe today that resembles the legendary Bogda. So there was a disagreement. Some people think that it is a legend, and the legendary Bogda does not exist at all. There are also people who believe that legends exist, because the things that have been in the legend for a long time are very similar to modern things, and even if they are coincidences, there are too many coincidences. Those who hold the latter view have inquired about the historical hydrology of the grassland and found that at the end of the Northern Song Dynasty, there had been major geographical changes in that area. However, the information recorded is vague and there is very little text. Those who hold the latter view speculate that there may have been a major earthquake in the area at that time. It is then speculated that the legend of Bogda is real, and that Bogda at that time had technology and civilization far ahead of its time, but a sudden earthquake destroyed the place. It's just that the legendary Bogda really existed in that era? When did it originate? There is no way to guess. ”

I said, "What about later?" ”

Ruoyu paused for a moment, then continued, "Later, the person who thought that the legend of Bogda was real, and with the support of a consortium, he cooperated with a university in China to conduct a field trip to the grassland, and I also went with the team. After arriving at the grassland, I found that the place where Yan Yan's tombstone was found was near the investigation site. In later investigations, although the intended purpose was not achieved, significant discoveries were made. At the other end of the grassland, the joint expedition team excavated another tombstone and a grave. The owner of the tombstone is called Tang Jiaxing. You shouldn't be familiar with this name, right? ”

Hearing Ruoyu say the name Tang Jiaxing, my heart was stunned. Of course I know Tang Jiaxing, and he is also one of the people we walked on Lop Nur back then.

Ruoyu looked at the reaction on my face and said, "We tested the tombstones, tombs, and bones of Tang Jiaxing, and later restored the portraits, which proved that Tang Jiaxing was one of the people you walked on Lop Nur back then." What's more, we found a notebook in the tomb of Tang Jiaxing. It seems to be his diary. ”

I nodded and said, "I know this Tang Jiaxing, he does have the habit of keeping a diary. ”

Ruoyu said, "Although this notebook is so rotten that it is unrecognizable, and it cannot be completely restored." But we tried everything we could, and we finally succeeded in restoring half of the page. The restored text left us ecstatic. The gist of the text is: I should let the god of war teach me how to kill enemies in flight, and do my part to defend Bogda. These texts prove not only the real existence of Bogda, but also the existence of Bogda in that era. ”

I said, "Even if that's what you say, what does it have to do with me?" ”

Ruoyu said, "A tour group of 20 people entered Lop Nur, two of them died 900 years ago, and the others were not heard from at all, only you are safe and sound, what can you say has to do with you?" You say, "If I don't look for you, who am I looking for?" ”

I said, "But that doesn't make you ask me to go to Tibet!" ”

Ruoyu said, "Of course, there is another reason for looking for you to go to Tibet. I'll pick up where I left off. Although the joint expedition team found Tang Jiaxing's diary, they could not find the ruins of Bogda on the steppe, which stretched for thousands of miles. Some people wondered, after the great earthquake that year, was Bogda completely destroyed? Did anyone survive? If there are survivors, where do these people go? Fortunately, with Tang Jiaxing's diary, someone made a data query on the migration of people at that time according to this era. In the search of materials, some people found that there was a strange record in the county records of a small county in the mountains of Sichuan. To the effect that late one night, the county seat was suddenly attacked. After the county seat was breached, the attackers fled. The attackers were unknown, but they did not loot anyone's belongings other than food. Although the county chronicle does not know the ins and outs of the attackers, the methods of attack recorded in it are almost exactly the same as those in Bogda's legend. Then, someone saw the same record in the county chronicle of a county on the border of Sichuan and Tibet. ”
