When I woke up, I opened my eyes and saw the light blue hotel ceiling in my sight.

After traveling through the parallel world for so long, and returning to reality again, Long Yun lay in a daze for a while before remembering what he should do.

Today should be the day to set off and return home, right?

I stayed in Singapore for two or three days. Even if I had a vacation, I still had a lot of team work waiting for him to do after returning to China.

The group took care of their luggage and took a special car from the hotel to the airport. Long Yun was carrying a suitcase given to him by Professor Liang in his hand, which should contain the documents they had come here this time.

Those precious documents that may be worth millions at the black market price but only cost less than 30,000 yuan were bought. They were packed in ordinary-style boxes and were not conspicuous at all. When passing through the security door and scanning through perspective, there was no problem. They were taken on the plane very smoothly.

After climbing onto the plane and putting the box in place, Long Yun was still wondering if this pass process was too simple. If someone took advantage of such a loophole, wouldn’t it be very convenient to take private flights to carry contraband?

But he soon thought that this should be because the relevant departments said hello in advance, otherwise it would be impossible to bring cultural relics out of the country easily like this.

Take off from Changi Airport, the Mercury 720 quickly moved away from the coastline and entered the South China Sea. Longyun checked the pilot status correctly and began a voyage back to China.

Indeed, the current driving method makes him feel like a driver at the front of the subway; with a highly automated driving system, generally speaking, he doesn't have to do anything except staring at the state of the display.

Just like when they came, Shangguan Ling and Professor Liang and his wife were still in the back cabin, but there was another locked password box; after landing, the relevant departments would naturally send people to take away these things, and their mission was successfully completed.

The process of obtaining the document this time was quite smooth, which made them less troubles in customs declaration and exiting the country; otherwise, if the conflict was caused by the unwise actions of the target person, it would not only alarm the local government, but also be afraid that the inspections at airports and other places would also be stepped up, so they would not be allowed to leave so easily.

Will the next few hours of voyage be spent like this boring again?

Thinking of the last trip, Long Yun wanted someone to chat with him; unfortunately, Shangguan Ling wanted to greet Professor Liang and his wife, so he probably wouldn't come here.

While he was thinking about it, he heard the sound of the cockpit door opening. Long Yun turned around and found that it was Professor Liang who was walking in. He hurriedly bowed to say hello.

"Professor Liang, please sit down!"

"Haha, I'm not polite," It seems that Shangguan Ling should have said hello in advance. Professor Liang sat down in the passenger seat and looked at the layout in the cabin with a little curious look. "Not to mention, it's the first time I've been in the cabin, I'm a little curious!"

Seeing Professor Liang's novel performance, Long Yun had nothing to do anyway, so he briefly introduced him to the CāO control method of the plane and the meaning of the data on the display. After a moment of communication, Long Yun knew that he still had some understanding of general flight control, and the conversation between the two became much more efficient.

"Ah, it's all like this now!"

With Long Yun's guidance, he understood what the colorful signs on the large display meant. Professor Liang nodded with emotion. "Now the cab of the plane has become so modern! When my thoughts are still on a lot of instruments, it seems that it is indeed out of date. - Hey, Long Yun, you don't have to move anything, just sit here to monitor the plane's flight?"

"Yes," Long Yun simply took his hand off the wheel. "Usually, pilots only need to pay attention to whether the system works normally. It is precisely because of this technology that flight is much safer. After all, people are not machines, and they may always make mistakes in their busy schedules."

After hearing Long Yun's words, after getting his confirmation, Professor Liang fiddled with the driving wheel and cāo control button in front of him with great interest. It seemed that as a scholar's curiosity, the professor did not fade at all.

Just talked and talked, and somehow, the topic returned to the purpose of their trip.

"Haha, this time is not bad! I haven't read the literature carefully yet, but the content is indeed very valuable."

"This, Professor Liang, what kind of literature is this about?"

I had a little understanding of Shangguan Ling and the so-called "historical science" studied by Professor Liang, and Long Yun took this opportunity to ask.

"Actually, there is nothing; we have known the general content for a long time. Now we have to come back mainly from the perspective of protecting cultural relics, retaining evidence, and safeguarding national dignity." Professor Liang habitually took out the cigarette box and paused, and then put it back in his pants with embarrassment. "This batch of documents are all technical records from the late Southern Song Dynasty, and they are indeed quite rare."

Technical records? This is the first time Long Yun has heard of something like this.

In his impression, in addition to poetry and verses and historical records, ancient documents seem to be left with only popular novels. As for technical documents, do they refer to things like "Compendium of Materia Medica" and "Zhouben Summary"?

He raised his own question, which caused Professor Liang to burst into laughter.

"Haha! I think so. Now many people think that ancient Chinese books should be poetry and historical books, but in fact they are not like this." He got up and returned to the back cabin, and after a moment he took back a book, "Hey, young man, you can read it if you have time. The so-called Wang Po sells melons, I won't say much about the content of the book I wrote myself, haha!"

"Oh, OK!" He took the book solemnly and Long Yun thanked Professor Liang, "So, what aspects of the content are recorded in these documents?"

"It mainly records some technical research collected in the late Southern Song Dynasty, including local governments, which were compiled and compiled by government agencies at that time. However, because the scientific and technological status was low at that time, such records were not included in the library, so it is not easy to find them now. Not only that, many Westerners are now studying the history of ancient Chinese technology and are looking for such first-hand information, so they are so rare and affordable."

Long Yun nodded, he still knew this.

In ancient China, although science and technology also played a great role in society, it never received the attention it deserved; among the ancient documents that have been preserved, there are the most historical books and records, while the materials on engineering are relatively scarce.

"Hey, sometimes I feel that there is a long way to go. Not long ago, the most authoritative works of our Chinese history of science and technology were actually written by foreigners. This is not only unreasonable, but also shows that we do not pay attention to this history, and even ignore it to a certain extent." Professor Liang seemed to be quite emotional, "And, the so-called 'reading history makes people wise' is not a false statement when used on this."

"Oh? How do you say this?"

Long Yun found it interesting, and he was thinking in his heart what kind of guidance would be given to today's scientific research.

"In this way, I will propose a theory and tell you now."

Professor Liang was obviously inspiration. He adjusted his posture to make himself sit in the seat more comfortable.

"For example, through the study of past historical materials, I found a very strange phenomenon. This phenomenon is called 'technology blowout', and the content is not novel. That is to say, in the continuous historical development, industrial and agricultural technology, especially basic theories, will stagnate for a long time, and then suddenly there will be a major development. Have you ever paid attention to this phenomenon?"

When Long Yun heard this, he lowered his head and thought for a while. He felt that this phenomenon was not uncommon.

"I think there are, such as nuclear theory and weaponization before and after the battle, as well as hydrogen crystal locking theory in previous years, which should be all."

"Haha, you have some modern examples. But that's right, let's take this recent one," Professor Liang paused for a moment without blinking his eyes. "If I had asked anyone, including scientists, twenty years ago, who would have realized that this kind of thing might exist? This kind of new technology and new theories that suddenly appeared are quite common in the history of science. Traditional theories often attribute this phenomenon to quantitative change and qualitative change, or the accumulation of long-term research by scientists; but in my personal research, the real implementation of many new ideas can often only be attributed to someone's 'inspiration'."

"……inspiration?"

"Yes, it's inspiration, or 'enlightenment'! This is the Eastern saying, it's OK. In short, no matter how common theories emphasize the importance of basic research and emphasize quantitative change to qualitative change; but in the end, there must always be a person who suddenly understands the essence of things and solves the most difficult and critical things in the entire system. This kind of thing has happened countless times in the history of science, so I am particularly doubtful: what kind of phenomenon does this inspiration, or epiphany, mean?"

Hearing Professor Liang's words, Long Yun thought a little confusedly; but he always felt that he could not grasp the essence of the matter, so he could only nod in a daze to deal with it.

"As an observer of science, not a practitioner, I may not have much say. But my view, this jumping development, is itself an insolvent mystery in the history of science.

After all, scientific research is on the objective world, not some subjective thing, right? But how can objective things have such characteristics - often not through planned research, but through a "light of inspiration"? Is this due to the way of thinking of the human brain or something else? I am still thinking about it now."

Professor Liang was still talking about his point of view slowly. While Long Yun focused on understanding, he also faintly felt an inexplicable feeling. This feeling probably comes from the "inspiration" mentioned by Professor Liang just now: Isn't it a bit unreliable to use this statement to explain the nature of scientific discoveries?

But on the other hand, Long Yun had to admit that many discoveries in modern science are really achieved in this way. If, as Professor Liang said, there were such rules in ancient scientific and technological development, then what does this phenomenon mean?
