Road to science and technology

Research on Lingzi has been going on for four or five years, during which time a lot of exploration has been done on the performance of the differences between the cultivation methods of good and evil monks.

Today was originally another day of rest after the experiment, but because many people participated in the research, in order to improve the enthusiasm and quality of the work, Yue Yuanzhou paid wages to these monks.

With the money from Shenzhou Civilization, they can theoretically buy visas to other worlds, but even just visas are not something they can afford with their current wages. After all, Yue Yuanzhou uses cheap labor. Therefore, the monks who worked for his experiments could only buy some Shenzhou civilization products.

Tian Buyi is one of them, but because he has a pass, he spends a lot of money. He bought two mobile phones that are currently open to their monks in the Shenzhou civilization.

In the Shenzhou civilization where artificial intelligence whale eyes and transformation technology are rampant, this is the cheapest smartphone. Tian Buyi bought two of them because he wanted to get one for his wife.

Because of the presence of Sophon, the mobile phones manufactured by Shenzhou Civilization do not need to build any base stations here.

This time Ertian Buyi was squatting in the living room getting familiar with this new communication tool. He thought this thing was really amazing.

But what he wants to know today is another thing, which has troubled him for a long time. It also troubled Daoxuan and Wan Jianyi because they had the same experience.

That's why they can't fly out of the land they're on.

After getting familiar with each other for a while, he called Daoxuan and Wan Jianyi, but Wan Jianyi was not interested in this question, so Tian Buyi had no choice but to call Daoxuan and walk towards Yue Yuanzhou.

Yue Yuanzhou was still very concerned about these wage earners who were cultivating immortals. After all, they would be relied upon to assist with research in the future, so the Qingyun duo walked to Yue Yuanzhou's office unimpeded.

"come in!"

The two of them had just walked to the office, still hesitating whether to knock on the door, when they heard Yue Yuanzhou's voice, and then they opened the door automatically.

In a very ordinary office, Yue Yuanzhou was sitting behind the desk. Behind him was a bookshelf, which contained some books that neither Tian Buyi nor Dao Xuanjian had ever seen. On the left side of the entrance is a large fish tank with several ordinary fish in it, and on the right is a sofa.

"Sit down, today is not an experiment day. If you don't have a good rest, why are you here with me?"

Yue Yuanzhou was writing a hypothesis about Lingzi this time, but he was a little distracted while writing just now, and these two guys happened to come over.

After the two sat down on the sofa, Daoxuan tugged on Tian Buyi's sleeve.

Tian Buyi understood, stood up again and bowed his hands to Yue Yuanzhou and said: "Senior, what we encountered when we flew into space before was that we could never fly into space. In recent years, we have been thinking about it but in the end we couldn't figure it out. Therefore, I took the liberty to come here today to ask for advice from my senior."

"Oh? This is what happened"

I thought it was something, but it turned out to be this.

The two of them were curious, and Yue Yuanzhou thought it was rare, so he took out a book on the introduction of Niu's Three Laws from the bookshelf and threw it to Tian Buyi.

Said: "Actually, it's not that you can't fly, it's that the way you fly is wrong. Next time you use your spiritual power and its reaction force as thrust to keep flying, you can fly out of the ground beneath your feet."

Yue Yuanzhou knew very well at that time that when these people flew, they were not only slow, but they also used spiritual power to act on the air. It was strange that they could fly across the earth.

Tian Buyi opened the book and browsed it, then handed the book to Daoxuan silently.

Daoxuan took the book and opened it carefully for a while, then handed the book back to Yue Yuanzhou with an embarrassed expression, clasped his fists and said, "Senior, please clarify your doubts."

When he said these five words, Daoxuan felt really embarrassed, especially when he saw Yue Yuanzhou's eyes as if he were illiterate. He felt like he had picked up a book called Peerless Cultivation Intensive and couldn't understand it after opening it.

In fact, he could understand it just now, and he could understand individual words, but when they were connected together, he couldn't understand it, let alone the strange symbols.

"Oh, I almost forgot." Since he was so engrossed in thinking about the problem just now, Yue Yuanzhou subconsciously forgot that these two were traditional immortal cultivators.

"I can only tell you that there are two ways for you to fly out of the earth. The first is to fly directly from the ground at a very high speed, and then directly break through the constraints of the earth. The second is to always use spiritual energy as jet thrust to fly. You can always fly across the earth.”

This is of course, the first one is equivalent to using large thrust to exceed the escape velocity. The second type is equivalent to a space elevator. A ladder is set up from the synchronous orbit to the ground. Every time a person takes a step upward, the relative linear speed will actually be a little faster. Until the space elevator climbs to the synchronous orbit where the space elevator is, its speed will be the same as on the orbit. The elevator stops at the same speed.

For example, the speed of the earth's synchronous satellites when launched on the ground must be greater than the first cosmic speed of 7.9km/s, but the speed when they reach the synchronous orbit and operate normally is 3.08km/s. If the satellite's speed suddenly increases based on 3.08km/s, the satellite will perform centrifugal motion and then reach a higher orbit.

The reason for this is that the gravitational force decreases exponentially as the distance from the earth increases.

"I understand, thank you senior!" Tian Buyi said and laughed.

He thought of the jetting method of Zhang Xiaofan's suspended motorcycle.

"As long as you know."

Yue Yuanzhou nodded. He didn't know whether Tian Buyi really understood or pretended to understand, but he didn't care.

Suddenly, he glanced at Daoxuan, his heart moved, and then he picked up a pen and wrote a sentence on the draft paper in front of him.

Then he circled some sentences as if he had figured something out, as if to indicate that this was the key point.

Yue Yuanzhou's move also attracted Daoxuan's attention.

So Daoxuan glanced at the desk and saw a line of words formed in Yue Yuanzhou's pen: "Tao can be a Tao, but it is not an eternal Tao. A name can be a name, but it is not a permanent name. Nothing is the beginning of all things. Yes is the name of all things. The mother of the body. Therefore, there is always no desire, so as to observe its wonders. There is always desire, so as to observe what it desires. The two come from the same place, have different names and the same name. There is mystery in mystery, and it is the door to all wonders."

Daoxuan looked at it and said secretly: That's not right! I didn’t expect that seniors would make mistakes sometimes.

Because he had read this book before, and it was obviously not written like this.

It seems that seniors are not good at certain fields!

Daoxuan thought about it and couldn't help but said: "Senior, there are some fallacies in it."

"Oh?" Yue Yuanzhou was a little surprised by Daoxuan's statement, because his words clearly came from the original words in the "Laozi" that Zhuangzi brought.

It was that ancient world at that time, when the pre-Qin philosophers and hundreds of schools of thought, including Mencius, Mozi, and Zhuangzi, are still living well in the Shenzhou civilization.

Now Daoxuan actually said that he wrote it wrong. How could this not make him feel strange?

Facing Yue Yuanzhou's doubts, Daoxuan asked confidently: "Is this the beginning of the Tao Te Ching written by my predecessor?"

Yue Yuanzhou frowned when he heard this, but did not explain directly. Instead, he asked: "How do you think it should be changed?"

Daoxuan's memory is still very good. He still remembered the book he read many years ago, so he read: "Tao can be Tao, but it is not Tao; it can be named, but it is not named. Nameless is the beginning of heaven and earth, but there is name, the mother of all things." Therefore, one should always have no desires in order to observe the wonderful things, and always have desires in order to observe the wonderful things. These two have the same origin but different names. They are both called mysteries. Mysteries are mysteries, and they are the door to all mysteries."
