Hao Zhi pulled a chair and sat down. He stroked his thoughts slowly, and then the two people in front of him preached.

"Do you remember the history told by the prophet?"

"Yes, remember!"

"Do you remember how those civilizations perished?"

"Because of the civilization ceiling theory?"

"Yes! The biggest obstacle to the development of civilization is precisely the contradiction between scientific and Technological Development and moral bottom line!" Hao Zhi concluded with confidence.

"What do you want to say?" Jia Jia didn't understand.

"If you think about it, we assume that aliens are a kind race, then they hide their knowledge in the light and convey it to other planets. Their purpose should be to contact each other and seek partners."

"Yes, there's nothing wrong. If we don't help the earth people's scientific and technological development, how can the two sides get in touch? It's like they have a telephone installed at home, but there's no telephone on the earth, they can't get through!" Jia Jia answered mischievously.

"That's right, but think about it. For decades, Americans contacted aliens and entered rapid development in the late World War II. What is the fastest developing weapon?"

"Yes..." Jia Jia also patted his thigh. "It seems that this is the case. After Professor Naduo established Tianhe computer, China's science and technology also developed rapidly, resulting in an arms competition between the two superpowers... God! How is this so similar to the situation between the Mayans and the Mu empire in the late civilization of the last season mentioned by the prophet?"

"So I think the reason why the prophet did not simply teach me the way to obtain knowledge, but repeatedly stressed the reason for the decline of civilization is to warn us not to blindly believe in the development of science and technology. The synchronous improvement of human spiritual civilization is the only way to ensure that we can cross the upper limit of civilization!"

"Only a mature mind deserves superior weapons and technology!" concluded professor nado.

"Yes!" Hao Zhi punched him in the palm of his hand, "That's the most important thing. On the contrary, we can know by reasoning. Aliens want to invade us, but they also transfer technology to us. Why? It's like I hate you two and want to occupy your territory. Then give you two a gun and wait for you to kill each other. I'll take advantage of each other! Lest I do it myself..."

"Sinister intentions!" Jia Jia shivered in her heart.

"So aliens only teach us how to rapidly develop science and technology and weapons, but the information transmitted does not include any knowledge about social system and spiritual civilization! As a result, mankind is currently advanced in the military of all countries in the world, but there are social systems of different levels and levels! The disunity of civilization and culture is bound to cause confrontation, and at that time, weapons will naturally be sent It's no use! "

Professor Naduo stood up excitedly and strolled around the room. For a while, he felt hot and dry, so he unbuttoned his coat, pinched one hand on his waist and waved excitedly.

Sima Zhao's heart! Sima Zhao's heart! He kept waving and shouting.

Hao Zhi's doubts are gradually being solved. After this conversation with the prophet, he has obviously enlightened his mind: "Therefore, I think it's better for us not to acquire the knowledge in the crystal skull. If we don't do this and establish Tianhe, there will be no later Lin Tao selling the human gene map, and the blood moon won't invade the earth. Let's live a good life, won't we..."

"Yes! Then we don't have to run so far to come here..." Jiajia echoed.

Many professors fell silent again. After a while, they still said resolutely, I'm afraid the fact is far from what you think

"What do you mean?" Hao Zhi said puzzled.

"In fact, Americans have begun to take off in science and technology. Our backwardness is obvious. If there is an opportunity to help our motherland become rich, strong and developed, even if it is dangerous, we can't give up. Otherwise, it's not aliens to destroy the earth, but we are destroyed by other powers. As a result, the difference is not big!"

Hao Zhi vented his anger in an instant. Indeed, many professors are also telling the truth. If they are backward, they will be beaten. As for who will be beaten? The method he proposed is too negative and undesirable.

"Moreover, according to what you told me about the future history, I found that you came at the wrong time!" Professor Naduo turned the conversation.

"Yes, we came at the wrong time. We came early. I was going to the beginning of 1997. Fortunately, I stopped Lin Tao from selling the genetic information of people on earth that year. However, Jiajia temporarily mixed in and disrupted the time flow. It's only 13 more years. It's back to May 1984..."

"No, no, I'm not talking about the wrong time!" Professor Naduo shook his head and smiled bitterly.

"Hmm?" Hao Zhi thought. Besides this time, is there any other time?

"You just pay too much attention to the surface phenomenon and pay too much attention to the time when Lin Tao sold the human gene map. In fact, this time is not important! It doesn't matter whether he leaked human secrets through Tianhe computer. The important thing is... According to your time at that time, the blood moon man set out for the earth as early as 500 years ago!"

"Ah?" Hao Zhi's mouth opened like a ladle. Yes, careless, careless!

Why did you miss such an important time point?

People came to you 500 years ago. To stop them, they have to go back 500 years ago

Hao Zhiyang began to calculate for a long time and finally worked out a number. Around 1850

"Yes!" Professor Naduo smiled. "It should have happened around that time that the blood moon man discovered the existence of human beings on earth!"

How can you be so sure? Hao Zhi asked in surprise.

"Hehe, it's about to start with my name. I'm a Manchu. There's nothing wrong with my last name."

"Na Ying is also na!" Jia Jia suddenly remembered.

"Yes, that's the seventh of the eight surnames of the Manchu clan. I won't say much about the specific history, but my real name isn't that much..." the professor laughed, "that's the name I changed myself later!"

"Oh? Why so much?"

In 1974, when I was 35 years old, in the third year after the establishment of diplomatic relations between China and the United States, the Chinese Academy of Sciences sent a group of researchers to the United States for exchange and study, and I also went with the team.

"Well, it seems that Xu zhe also said... It was at that time that you found the alien technical data in the hands of the Americans."

"Haha, what is the information left by aliens? We were visiting the museum. In order to pay tribute, the curator showed us a valuable historical material, which is a 7000 page Da Vinci manuscript repaired over the years!"

"Da Vinci? Mona Lisa?" Hao Zhi blurted out.

Yes, Professor nado smiled. Leonardo Di Piero Da Vinci, this is his full name, and I took the two words related to my last name to express my admiration for this great man

"I made a song!" Hao Zhi said he didn't understand. "Do you mean that your later notes also refer to Da Vinci's manuscripts, and all the knowledge you have beyond the times was learned from a painter?"
