Xi'an, known as Chang'an in ancient times.

It is one of the four ancient capitals of the world, and it is also a place that has been listed as the first choice by the rulers of all dynasties.

The weather in June and July is always gloomy, and pedestrians on the road are more or less affected by this weather. People in a hurry can be seen everywhere.

A slender black-clothed young man with a backpack appeared in everyone's field of vision, perhaps because of the weather, some white lips were gently pursed, and his steps seemed a little anxious.

In a café near the west exit of Chang'an Avenue, Xu Mo has been sitting in it for a while. The teacup at the table was steaming.

The café is typical of Tibetan style, with antique prayer wheels inlaid on the walls, several Buddha statues on heavy felt cloth, and a large bronze incense burner in front of the central hall.

It looks different from the style in Tibetan Buddhism, and it seems to be imitating the pattern of Central Plains Buddhism. It has a strong woody fragrance, and it smells reassuring and sleepy, and you can see that the owner has put a lot of effort into it.

The shopkeeper he had seen a few times, a middle-aged man with a beard, clean and neat, with few words, although he came a lot of times, but there was never much intersection.

Outside the window is the noisy prosperity of Xi'an City, compared with the interior, people feel that it is always a little abrupt and uncomfortable, or maybe it is a response to the sentence, quiet words in the noise.

Affected by his work, Xu Mo has an unspeakable antipathy to a certain degree of disharmony and resistance.

Picked up the teacup on the table and blew it. Approaching the evening, the number of people in the café has increased one after another, several universities near Chang'an District are here, and the south exit of Chang'an Avenue is the subway entrance of Line 1.

Xu Mo looked at his watch a little irritably, for this meeting, the other party was obviously late, so it was destined that the pleasantness of this conversation would be greatly reduced.

Finally, when he was close to the limit, she was late, although there was a difference from the photos on the Internet, I have to say that she was still a delicate woman, with a good-looking black eyebrow line, and a pointed chin with a soft curvature just right, just like a delicate doll, a little more or a little bit will destroy the beauty.

After many years of career in the position, Xu Mo developed antibodies to the creature of beauty, and with a straight face, she seemed to see his unpleasantness. A faint smile. Say goodbye. And handed him a black business card.

Hello, my name is Yao Yan.

Xu Mo nodded slightly, accepted the business card, she smiled indifferently, sat down and ordered a cup of green tea. Cut to the chase.

He and Yao Yan met through a foreign anecdotal forum, which is not very active, but the internal anecdotes are not bad, and it is a good place to wander around and improve your knowledge of things that are usually not interesting.

One day, Xu Mo, who was wandering around the forum, was attracted by a picture of snakes randomly sent by netizens.

Because of the problem of occupation, there are some academic exchanges, and after a careful look at the photos, according to the stratigraphic analysis, it can be preliminarily judged to be the product of the early Quaternary of the Cenozoic Era, because the Quaternary sediments are very extensive and relatively intact.

This is also due to the fact that the Quaternary is in a great ice age, but compared with the Quaternary antiquities found in the past, the difference in this picture attracts people's attention, in front of the computer, Xu Mo, who has been carefully studied, is in a cold sweat, creepy.

The Tertiary angiosperms were extremely vigorous, and the rest of the gymnosperms tended to decline except for the pine and cypress which still occupied an important position. Ferns have also been greatly reduced and their distribution is mostly confined to warmer regions.

With the strong orogeny and cold climate of the earth, most of the plants have perished, and most of the plants that survived were relict plants.

Plants such as silver fir and metasequoia are the representatives of relict plants, and those who know know that most of these relict plants are not small, and several ancient trees next to the snake bone attracted his attention, although he is not targeted at studying ancient trees, but he can also roughly distinguish the approximate difference between relict plants and other plants, but at this time, through the size ratio of relict plants and snake bones, you can find an amazing thing.

This snake bone is surprisingly large, if it really exists, then the length of this snake is conservatively estimated to be more than 100 meters.

Xu Mo, who came to this conclusion, was in a cold sweat, and the instinctive latent consciousness in his brain made him think of the possibility of fraud, but with careful observation, he denied this possibility. With intense curiosity. He contacted the friend in the forum to find out.

Xu Mo, who was playing with the teacup in his hand, asked casually, "Miss Yao, if it is convenient, can you tell me the origin of this photo?" You also know what kind of waves it will set off in the archaeological community if the content recorded on this photo is true. ”

"That would undoubtedly be a bombshell in the archaeological community, and it would be able to overturn many existing paleontological theories. Of course, if it's fake, then it's a different story. ”

Yao Yan looked at him and said very simply, "Mr. Xu, I know you will suspect that that photo, I can guarantee that it is absolutely true, and there is no half-point falsification, when I got this photo, I also consulted some relevant literature, and I also know a series of consequences caused by the appearance of this photo, so when you first asked to meet, I would have some necessary concerns." ”

Speaking of this, she paused and said, "If it wasn't a last resort, I wouldn't have asked for help from the Internet." I won't have this meeting with you. ”

There are words in the words, Xu Mo's biggest flaw is also his biggest advantage, his curiosity is too heavy, he nodded lightly, and motioned for her to continue.

I have to say that after looking closely, she is very attractive, especially the kind of confidence that exudes from her body, which deeply attracts the man sitting opposite her.

While secretly sighing in his heart that this woman is not simple, it also increases his curiosity about this matter.

When Yao Yan was in college, there were two good friends of a man and a woman, and these two were senior travel friends, in addition to the winter and summer vacations, they would secretly travel when they didn't have classes, and many well-known attractions in China were not missing, and even some of the attractions that were rare and had not yet been developed.

Relying on his youth and courage, and some excellent self-protection methods, he also went smoothly, and there were no major problems, and because of this, Yao Yan was also relieved for the two of them, but even so. She also kept an eye on it, and asked the two to contact her every other week. And from the hands of the two people, they asked for GPS positioning devices and encrypted information of their computer files.
