Su Yichen didn't expect that he would see something almost impossible here because he saw a pyramid! That's right, it was a pyramid, which was exactly the same as the Egyptian pyramid in the data picture in the university library.

Perhaps, this statement is a bit twisty, but not far from Su Yichen's direction, that is, about ten meters away, a pyramid is standing in front of him. Of course, this pyramid is not as tall as the Great Egyptian pyramid in the picture album, but it is not small in terms of outline. Looking at the slightly beating fire, the hazy tower body is about five meters high, and from the outside, it is completely in line with all the shapes and proportions of the pyramid. According to the standard circumference and height ratio of the pyramid's base edge, that is, the well-known calculation formula of pi π (3.1416), Su Yichen can immediately find that its oblique edge should be 7.5 meters and the bottom edge should be about 7.9 meters.

Although there are no measurement tools, Su Yichen, who is proficient in mathematics, can still draw conclusions from its outline. The angle between its oblique edge and the ground is about 52 degrees. From these data, it can be proved that this small pyramid is exactly the same as many pyramids in Egypt.

If there is a difference, of course there are. The size is not big, because in Egypt there are also small pyramids in addition to the Great Pyramids, but their material and workmanship are not comparable to those of Egypt. Regardless of the size of Egypt's pyramids, the size of Egypt is made of huge rocks cut by artificial piles. With thousands of years of weathering, it seems to be integrated from a distance, but it is very rough in the near view.

Of course, Su Yichen has never been to Egypt, and he has never even been to the country, but don't forget that Su Yichen is a doctoral student in the School of Science and a professional who is proficient in mathematics. In the subject of mathematics, the clever combination of the golden ratio and pi of the pyramid has always been a professional research topic. Although Su Yichen's main research goal is not in this direction, he has read these materials out of interest in his professional courses, so he is not unfamiliar with some detailed introductions to the pyramids and construction structures.

Although the appearance of the small pyramid in front of him is exactly the same as that of the Egyptian pyramids, it is much more refined than that of the Egyptian pyramids. With the faint light of fire, Su Yichen felt a little confused for a moment because he didn't understand how the pyramid that clearly originated in the Nile River Basin appeared in this place. What's more, when he approached, he looked at the pyramid carefully, and the strange building in the desert flashed through his mind.

Yes, it was the exterior of the building where Su Yichen was now. The pyramid in front of him had a well-integrated shape and its appearance that looked slightly dull and gray in the fire. Su Yichen could easily think of it. In order to confirm, he approached carefully, came to the pyramid, reached out to touch the appearance, and the moment his palm touched the appearance, Su Yichen was completely sure that the materials of this pyramid should be the same as the materials of the building they encountered in the desert.

The second match had been burned long ago. Su Yichen had now drawn the fifth lit match and also circled the pyramid several times. Although there were still many matches in his pocket, Su Yichen did not dare to continue wasting them at all when he could find Wan Changchun and Hu Zhijun, including finding a way out. Just as Su Yichen walked around again, he could only confirm that the pyramid was the same material as the surface of the building they had contacted before, and without any other new discoveries, he planned to stop staying here because without all the instruments and equipment, the results could not be studied. Moreover, the most important thing at the moment was to find people first. Su Yichen, who was worried about the safety of Wan Changchun and Hu Zhijun, decided to go to other places to see, and at least he had to figure out where he was now.

At this moment, when the matches in Su Yichen's hand were about to be extinguished, he suddenly found a strange pattern on the front of the pyramid. The pattern was actually not big, and it was about the size, which was slightly larger than a person's palm. Moreover, the pattern was also quite special, it was a pyramid-shaped look, or more accurately, a pattern similar to a geometric equilateral triangle.

In this triangle pattern, there are some slight highlights flashing and jumping, as if the part of this pattern is completely different from the rest of the pyramid, and the texture is slightly different.

Su Yichen couldn't help but exclaim. He hadn't noticed it before mainly because the position of the pattern was slightly higher, about 10 cm above his chest, and the highlights in the pattern were not visible at a glance. Only when facing it directly, that is, when the eyes and the pattern were at right angles, and the matches in his hand could be visible.

In order to prove this, Su Yichen deliberately moved a little to the left and looked at it from another angle. At this time, those highlights were gone, and even the outline of the triangle could not be seen. From this angle, the position of the pattern was not different from the rest of the pyramid.

After discovering this, Su Yichen suddenly became curious. He returned to the position where he was standing, drew a match again, and then looked closer and looked at the pattern. At this time, the highlights inside the triangle lit up one by one, but these highlights were not always lit up, but were constantly flashing like stars, one, two, three, four... Su Yichen could not count how many highlights were flashing. The highlights that were even more subtle than the tip of the needle were dense, with different sizes and brightness. The closer he looked, the more Su Yichen felt that this was not the highlight, it was clearly a starry sky of the universe.

"Is this astronomy star map?" Su Yichen felt a little incredible. Mathematics and astronomy are interrelated. Although Su Yichen had never really dabbled in astronomy, he was not ignorant of the star map of astronomy. At least he could still recognize one or two of the star maps of the solar system and those famous constellations. However, the star map in this pattern (let's think it is a star map) made Su Yichen unable to see at all. He only felt that it was too similar to the star map of astronomy.

In a blink of an eye, Su Yichen remembered another coincidence, because he remembered a document he read when studying the mystery of the coincidence between the Egyptian pyramids and mathematics. This document shows that when people opened the pyramid, entered and investigated the inside of the pyramid, they found that the ancient Egyptians who built it left several star maps in the ceiling of the inner secret room of the pyramid. These star maps were not portrayed casually, but were extremely accurate. In some star maps, modern scientists incredibly discovered that there were several stars inside. What surprised the world was that these stars were definitely not discovered by the ancients of that era with their naked eyes, because the discovery of these stars had clear records in the history of science. It was not until the late 19th century to the early 20th century that due to the continuous development of astronomy and more powerful astronomical equipment, such as professional astronomical telescopes, were discovered one by one after the emergence of them.

This mystery cannot be explained so far, and all scientists cannot use any scientific theories to explain why the ancient Egyptians recorded these stars that were impossible to discover by the naked eye in the star map left by the pyramids thousands of years ago. Su Yichen had only read this information a little, but at this time, the content of this information came into his mind very clearly.
