An academic seminar on global society and human progress was held in the international lecture hall of the famous Yenching University in Country G. The meeting invited experts and scholars from around the world who have in-depth research on Mayan culture.

At the meeting, Du Yuesheng, a famous professor at Yenching University, gave an academic report on "The Magical Maya" on stage-

In his academic report, Professor Du Yuesheng listed the various discoveries of Mayans, Mayan culture and Mayan ruins in recent years, and came to an astonishing conclusion: "After years of research, I can be sure that Mayan culture is alien culture, Mayans are aliens. We Earthlings did not evolve from apes to humans, we are alien species, we are prisoners exiled to Earth by Mars and other planets. The Earth itself is an interstellar prison."

After Professor Du Yuesheng's "The Magical Maya" academic report was published in major electronic newspapers, magazines, the Internet, video media and other communication channels, it caused a thousand waves. There were all kinds of discussions. His views attracted the attention of people around the world. Every day, he received emails and electronic messages from all over the world, and there were too many time to take care of them.

Today, he received an email, which attracted his special attention. Because judging from the prefix of this email, it was sent from a famous electronic research university in China. Electronic research is incompatible with his field. He clicked the email with curiosity, wanting to see what it was written in it, and found that it was actually from his old friend Professor Lin Sen whom he had not contacted for many years, and the email said in the email-

Yuesheng's old friend:

I haven't seen you for many years, and you are still so persistent in studying the relationship between Mayan culture and earth culture. In recent times, all media have been paying attention to your academic report on "The Magic Maya". I also read it. I am not concerned about your academic report about "Earth people are alien species, the earth is an interstellar prison" and so on. What I care about is a photo of you, which is the photo of the square decoration with a gold necklace.

I have carefully studied the photos you sent. I think it is not an ordinary decoration, just like your opinion. I think if the Mayans were more modern than the Earthlings, this decoration should be a product of modernization. I am engaged in electronic research. Can you bring that square decoration to me for research? We will discuss it in depth from another field, and maybe we will make a key breakthrough in the understanding of the Mayans and Mayan culture.

I hope we can meet. My contact number: ××××××

Your old friend: Lin Sen

After reading the email, Professor Du Yuesheng immediately called Professor Lin Sen. After brief greetings and greetings, the two agreed to meet at Yenching University three days later.

In the reception department of Yenching University, Professor Du Yuesheng handed over an exquisite box to Professor Lin Sen and reminded: "Whether it can be solved or not depends on you."

Professor Lin Sen, who was sitting on the sofa, took the exquisite box, looked at it and said, "I am not sure how to crack it. What it is, I will never dare to make inferences after I take it back and study it. However, there are quite a lot of instruments in our laboratory. With the help of our advanced instruments, we can see if there are new discoveries. If you didn't say in the photo, you scan and detect that it is a graphene decoration, I wouldn't be interested in it."

Professor Du Yuesheng asked strangely: "Are you interested in graphene decorations? You are a researcher in electronic products. How did you change your career and do research on metal materials?"

Professor Lin Sen told him: "I know nothing about metal materials. I just feel a little strange about the graphene ornaments you mentioned."

"Why?" Professor Du Yuesheng said curiously.

Professor Lin Sen asked back: "Think about it, are graphene used as decorations on our earth?"

Professor Du Yuesheng replied: "Maybe there is, but I didn't find it."

Professor Lin Sen said: "I can say for sure that there is no. The ones we sell in our stores are usually decorated with metal materials such as gold, silver, copper and iron. The most expensive are exquisite decorations made of diamonds, jades, jewelry, etc. I have never seen decorations made of graphene. What is graphene used for? It is widely used, especially in electronic products. I think it would be an electronic product."

Professor Du Yuesheng said: "It would be too strange if it was an electronic product. This thing is wrapped tightly and protected so well... But its function doesn't seem to be obvious."

Professor Lin Sen shook his head and said, "If it is an electronic product, there must be secrets we don't know inside it, which will be of great help to promote the development of our people on earth."
