The academic symposium on global society and human progress was held in the international lecture hall of the famous Yenching University in country G, and experts and scholars from all over the world who have in-depth research on Mayan culture were invited.

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

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

After Professor Du Yuesheng's academic report "The Magical Maya" was published in major electronic newspapers and magazines, the Internet, video media and other communication channels, it stirred up a thousand waves with one stone, saying that there were all kinds of discussions, such as good and bad, and his views aroused the attention of people around the world. Every day, he receives emails and electronic messages from all over the world, and the number of them is too large to take care of.

Today, he received an email that attracted his special attention. Because judging from the prefix of this email, it was sent from a well-known university of electronic research in China. Electronic research was not related to his field, and he opened the email very curiously to see what 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-

Old Friends of the Month:

I haven't seen you for years, and you're still so obsessed with studying the relationship between Mayan culture and earth culture. Recently, all the media have been paying attention to your academic report on "The Amazing Maya", and I also took a look at it, I don't care about your academic report about "earthlings are alien species, and the earth is an interstellar prison" and so on, what I care about is a photo of you, that is, a photo of a square ornament with a gold necklace.

I have carefully studied the photograph you have sent, and I share your opinion that it is not an ordinary ornament. I think if the Mayans were more modern and civilized than the earthlings, this ornament should be a product of modernization. I'm engaged in electronic research, can you bring that block ornament to me to study, we will delve into another field, maybe we will make a key breakthrough in the understanding of the Mayan people and Mayan culture.

Hopefully we'll be able to meet. My contact number: ××××××

Your old friend: Lin Sen

After reading the email, Professor Du Yuesheng immediately dialed Professor Lin Sen's phone, and after a brief greeting and greeting, the two agreed to meet at Yenching University in three days.

In the reception department of Yenching University, Professor Du Yuesheng handed a beautiful box to Professor Lin Sen and advised: "Whether you can crack its secret or not, it's up to you." ”

Professor Lin Sen, who was sitting on the sofa, took the exquisite box, looked at it and said, "I'm not very sure that I can crack it. What exactly it is, I won't dare to make a deference until I take it back and study it. However, we have a lot of instruments in our laboratory, and with the help of our advanced instruments, we can see if we can make new discoveries. If it weren't for the fact that you said in the photo that you scanned and detected it as a graphene ornament, I wouldn't be interested in it. ”

Professor Du Yuesheng asked strangely: "Are you interested in graphene ornaments?" You are researching electronic products, how did you change your career to metal materials research? ”

Professor Lin Sen told him: "I don't know anything about metal materials, I just feel a little strange about the graphene ornaments you mentioned. ”

"Why?" Professor Du Yuesheng was curious.

Professor Lin Sen asked rhetorically: "Think about it, do we use graphene as decorations on the earth?" ”

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

Professor Linsen said: "I can say with certainty that no. The ornaments we sell in our shop are generally made of metal materials such as gold, silver, copper, iron, etc., and the precious ones are also exquisite decorations made of diamonds, jade, jewelry, etc., and I have never seen ornaments made of graphene. What is graphene used for? It has a wide range of applications, especially in electronic products, and I don't think it will be an electronic product. ”

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

Professor Lin Sen shook his head and said, "If it is an electronic product, it must hide secrets that we don't know, which will be of great help to promote the development of our earthlings." ”

Professor Du Yuesheng said: "If it is as you say, this graphene cube ornament will be priceless...... I'm really looking forward to a surprise from your research. ”
