"Of course I know what the Guizhou Tianyan is."

Lin Xian looked helplessly at Liu Feng, "I asked you to repeat it, not because I didn't hear clearly... but because I wanted to make sure you knew what you were talking about."

Sigh.

Lin Xian sighed inwardly.

The Guizhou Tianyan, also known as FAST (Five-hundred-meter Aperture Spherical radio Telescope), is very well-known in Dragon Country and even worldwide. Especially for science fiction enthusiasts like Lin Xian, it's a familiar name.

As Liu Feng said, it is the world's largest radio telescope, covering a total area of over 260,000 square meters.

From the proposal of the construction plan in 1993 to the completion of the installation of the last reflecting unit in 2016, it took a total of 23 years.

To avoid urban signal interference, such large astronomical telescopes are generally built in mountainous areas far from cities. The mountainous terrain of Guizhou, coupled with the fact that the altitude is generally above 1,000 meters, makes it a uniquely ideal location for construction.

The shape of the Guizhou Tianyan is very unique. It looks like a silver pot set in the mountains.

Traditional radio telescopes are generally radar-shaped, or similar to radar shapes, but this super pot with a diameter of more than 500 meters obviously cannot stand upright, so it is built into this lying structure.

Around the big pot, that is, the reflecting surface, there are six supporting towers nearly 100 meters high. Each tower pulls out a steel cable, suspending a white "small box" above the "heart of the pot," directly above the giant reflecting mirror.

This 30-ton small box, officially called the feed cabin, is the core device of the Tianyan radio telescope.

The feed cabin is located at the focal point of each parabolic reflecting surface, and its function is to focus the signals collected by the reflecting surface to achieve high-sensitivity space observation.

During operation, the reflecting surface must be deformed according to the movement of the observed celestial body, the shape of the parabolic surface will also change, and the position of the focal point will also change, so the position of the feed cabin must also move accordingly... This is a very complex system.

It is worth mentioning that radio telescopes and optical telescopes have different principles. Optical telescopes form visual images as commonly understood by focusing visible light.

Radio telescopes, on the other hand, converge extremely weak long-wave electromagnetic waves in the universe... It is not a traditional telescope in the traditional sense. Its sensitivity and observable range are much larger than those of optical telescopes, but it does not have traditional imaging functions. It mainly records the observation of waves, vibration frequencies, and radiation.

In recent decades, the discoveries of pulsars, quasars, cosmic microwave background radiation, and interstellar organic molecules, which have been hailed as the four major discoveries in the field of astronomy, have all benefited from radio telescopes.

Among all the large and small radio telescopes in the world, the Guizhou Tianyan, also known as the Dragon Country Tianyan by world astronomy enthusiasts...

Undoubtedly, it is the strongest on the surface.

...

Lin Xian bent down, picked up the water pen that had been thrown on the ground, and put it on the table. "The Guizhou Tianyan is a national treasure. Although it is usually open to tourism, most of the time it undertakes very important astronomical observation tasks, and sometimes those tasks involve state secrets, so the Tianyan will be closed to the public."

"But no matter what, even if this thing has no scientific research tasks and is purely open to tourism every day... I can't buy this equipment for you!"

"This is not a question of whether there is enough money; this is a national treasure that is not for sale, and you can't buy it just because you have money. And even if you have money, without the technology and national support, it is impossible to replicate the same Tianyan."

"Even if we take ten thousand steps back, Liu Feng, even if I am willing to spend money to rent it for a few days, I am not qualified. I haven't checked in the past few years, but I have read relevant reports before. Many countries around the world are queuing up to apply for borrowing the Tianyan... It is so troublesome to borrow in the name of the country, this is not something a small company owner like me can handle."

"But..." Liu Feng scratched his head, showing a troubled expression. "I just told you that if *shi kong li zi* (space-time particles) really exist, they are very small and difficult to observe. Apart from a super radio telescope of the Guizhou Tianyan level, I don't think any equipment on Earth can capture the fluctuations and frequencies of *shi kong li zi* (space-time particles)."

"So, Lin Xian, I know it's difficult to borrow the Guizhou Tianyan, but this is an indispensable part of our research on space-time curvature and the study of the universal constant... If we can't find *shi kong li zi* (space-time particles), we can't reset the space-time clock; if we can't calibrate the space-time clock, we can't detect space-time curvature, and the entire research cannot continue."

...

Lin Xian tapped the table with his fingertips, without speaking.

He had actually wanted to tell Liu Feng long ago, to tell him that perhaps the universal constant was not as complicated as he thought.

After all, Da Lian Mao's father could figure it out with a pen and a few pieces of paper, so this thing may not require the world's largest radio telescope.

But after hesitating several times, Lin Xian still didn't say it.

First of all, Liu Feng is not Da Lian Mao's father, so there is no comparability. Da Lian Mao's father is a genius who won the Fields Medal in mathematics, a true genius, hard to come by.

In comparison, Liu Feng has not had any outstanding achievements so far. If you have to say it, his most important contribution to human history may be the book accidentally left in Li Qiqi's tomb, which inspired Da Lian Mao's father.

So, the two are not comparable.

Secondly, Lin Xian cannot be 100% sure that Da Lian Mao's father's research results are correct.

All along, he was just guessing, proving by contradiction, and felt that since the Genius Club was afraid, then Da Lian Mao's father must be right.

But there is no real evidence.

Therefore, saying such disappointing words now is meaningless and will only dampen Liu Feng's enthusiasm.

In the first dream, Da Lian Mao's father was killed in a car accident at 00:42.

In the second dream, Da Lian Mao's father was picked up on the morning of August 28, 2624, and missed him.

In the third dream, Da Lian Mao's father died of radiation sickness when Da Lian Mao was a child, even earlier, perhaps before he even had time to come up with any research results.

In short, in the current three possible futures, he has never met Da Lian Mao's father.

If Lin Xian has any hope...

He really hopes to see the living Da Lian Mao's father in the fourth dream in the future and directly ask this peerless genius what the universal constant 42 is!

But at the moment, these are all unreliable and unassured things.

It is very likely that he will never see the living Da Lian Mao's father in his lifetime, just as he did not find Time Bank or CC in this third dream.

The changes in time and space are too complicated.

This is a chaotic system with no rules to follow. A single move affects the whole body, and everything is unpredictable.

So there is no way.

Nowadays, Liu Feng is still Lin Xian's only "lifesaver," the person in the world closest to the truth of the universal constant 42.

Coming back to his senses...

Liu Feng had already run up to him with the small blackboard, pointing to a complicated string of numbers and letters on it. "I've already calculated it. By entering this string of parameters into the Guizhou Tianyan radio telescope program to match and search, we may be able to find the existence of *shi kong li zi* (space-time particles) in the universe."

"Of course, I know what you want to say, Lin Xian. Listen to me first. The fluctuation of this string of parameters is too small, so even with the world's top sensitivity of the Guizhou Tianyan, it is absolutely impossible to detect *shi kong li zi* (space-time particles) in areas outside the lunar orbit... because the precision is not enough."

"So, if the Guizhou Tianyan radio telescope can really find the existence of *shi kong li zi* (space-time particles), then it must be in the Earth's atmosphere! At the farthest... it will not be farther than the lunar orbit!"

"It can't be 380,000 kilometers away. I estimate that the farthest is tens of thousands of kilometers at most."

"I said this, you already understand, right, Lin Xian? We are very close to success!"

The more Liu Feng spoke, the more excited he became, patting the small blackboard and staring at Lin Xian. "If the Tianyan radio telescope detects a target that is relatively close, we can find a way to capture it! Can you understand how exciting this is!"

Liu Feng widened his eyes. "We can capture a reference object from another space-time! Capture the first in human history—"

"*Shi kong li zi* (space-time particles)!"

"Lin Xian-xuezhang (senior)?"

Suddenly, a light and clear call came from the laboratory door.

Lin Xian and Liu Feng turned their heads at the same time and looked towards the door.

There stood a beautiful girl in a white dress, her high, fluffy ponytail full of elasticity, her beautiful face filled with youthful vitality, the tear mole at the corner of her eye was the finishing touch, and her refreshing smile plus those signature crescent-shaped eyes—

"An Qing?"

Lin Xian stood up from his chair and looked at Chu Anqing at the door. "Why are you here?"

"I saw your car downstairs!"

Chu Anqing smiled sweetly. "We're going to the dance studio for shaping class next period, and I happened to pass by here and saw the business car downstairs... At first, I thought it was Zhao Yingjun-jiejie's (sister's) car, because I often see her riding in this car."

"But after taking a closer look, I found that the driver sitting inside was not Yingjun-jiejie's (sister's) driver, and the license plate number was also wrong... After asking, the driver told me that this was your car, so I said I'd come up and say hello!"

"I didn't expect it, xuezhang (senior). You actually bought the same car as Yingjun-jiejie (sister). I originally thought you would buy a sports car. After all, your driving skills are so good. Driving that kind of exaggerated car must be so cool!"

Lin Xian smiled slightly. "This car is provided by the company for business trips. The driver is also provided by the company. This is all the idea of Vice President Wang-ge (brother). I haven't managed the company's affairs much. If I really buy a car for myself in the future, I might really buy one with better performance... But I'm basically tired of driving, and it's more comfortable to sit in the car."

Chu Anqing tilted her head and looked at Liu Feng. "Lin Xian-xuezhang (senior), this is...?"

Her first feeling was that this person inside should be a teacher or professor in the laboratory.

But he seems a little too young.

Although the other party looks a little tired and haggard, he shouldn't be very old, at most four or five years older than Lin Xian, no more than 30 years old.

"This is Liu Feng."

Lin Xian turned his head and introduced to Chu Anqing, "A mathematician."

"I can't be considered a mathematician." Liu Feng nodded to Chu Anqing as a greeting. "I'm just an ordinary person doing mathematics. I don't have any achievements."

"So you're a mathematician. I thought you were a physicist or astronomer!" Chu Anqing smiled. "I heard you talking about some very profound things at the door just now, like the Guizhou Tianyan and radio telescopes. Oh, and..."

Chu Anqing blinked her eyes, her index finger on her chin, looking up at Lin Xian. "*Shi kong li zi* (space-time particles)... what is that?"

...

...

Lin Xian thought for a few seconds and said with a smile, "It's a name that Liu Feng made up, not something that has been proven. We were just discussing some astronomical research findings, and then we got carried away... and talked about something a bit sci-fi."

"So that's how it is." Chu Anqing suddenly understood, looking at Lin Xian with a sparkle in her eyes. "But Lin Xian-xuezhang (senior), you're really amazing. You know everything about astronomy and geography, and you're proficient in everything: piano, chess, calligraphy, and painting. Last time we went to the art exhibition together, you told me a lot of scientific knowledge besides art knowledge."

"At that time, I thought you might just have a wide range of knowledge and know a lot. But I didn't expect... you, as a liberal arts student, are also so knowledgeable in the field of science! You're really an all-rounder. I feel like you're really good at everything!"

"No, no." Lin Xian said modestly, "You're exaggerating a bit. I mostly just dabble in these things and stop there. I'm far from being proficient."

"Sigh..." Chu Anqing sighed softly. "To be honest, sometimes I'm really envious of you talented and capable people. Whether it's you, Ji Lin, Tang Xin-jiejie (sister), or Yingjun-jiejie (sister)... you all have very powerful skills and are very excellent people."

After saying that, she started counting on her fingers. "Look, I won't mention you, Lin Xian-xuezhang (senior). You always give people surprises. You're smart and knowledgeable. I'm very sad about Ji Lin's death, but after all, he did something wrong, and there's no way around it, but his writing is really good. Tang Xin-jiejie (sister) is the same... not only does she play the violin well, but she's also a scientist with some achievements. Not to mention Yingjun-jiejie (sister), she's beautiful, kind, and very capable. My father often mentions her and praises her."

"Many people are very powerful. I feel like everyone around me is excellent. Only me..."

Chu Anqing pursed her lips, looked up and smiled with her eyes narrowed. "Compared to you, I feel like I'm nothing but Chu Shanhe's daughter."

"You can't say that."

Lin Xian quickly took over the conversation, wanting to praise Chu Anqing.

But he found...

There doesn't seem to be anything worth praising!

If you have to say it, Chu Anqing's dancing skills are still very good, but to be honest, they are not amazing to the world. The reason why she can be on many stages, perform in many programs, and receive flowers and applause... everyone knows what it is because of.

Chu Shanhe.

Because she is Chu Shanhe's daughter.

That's why she has everything now.

She is not the best dancer in the entire Donghai University, nor is she the best dancer in the entire Donghai City.

But she is the only girl who can dance solo at the Donghai City Music Concert.

Not because she dances well.

Just because she is Chu Shanhe's daughter.

So...

In a sense, Chu Anqing didn't say anything wrong.

Rather, she actually knows this better than anyone else, has self-awareness, and knows that if she leaves her father's halo and love, she is just an extremely ordinary girl.

Except for being a little cuter and prettier.

Her studies are not considered excellent,

Her sports are just average,

The so-called good foundation in dance is also because she had 1-on-1 guidance from famous teachers since she was a child, taking a step ahead,

Her mind is not considered a genius,

She has no other special skills that she can show off,

She is not considered knowledgeable in terms of knowledge and insights,

For a moment...

Lin Xian didn't know how to comfort her.

With Chu Anqing having such self-awareness, saying any unrealistic praise is more like a satire than comfort.

He felt choked.

Lin Xian realized today that Chu Anqing is so ordinary. This is something he hadn't realized before.

But if this continues... I'm afraid it's even worse!

Lin Xian took a breath—

"Hehe, little sister, you can't think like that."

Uh.

Before Lin Xian could finish his breath, Liu Feng walked up with a smile and said to Chu Anqing, "You're young. It's too early to think about these things. And... no one can say for sure where the highlight of a person's life is. Speaking of which, if we're talking about being nothing and useless... then I have more of a say than you."

Liu Feng pointed to himself. "I've liked mathematics since I was a child. I studied mathematics throughout my university and graduate studies, studying a topic that no one recognized and was completely wrong. For so long, I have never succeeded once, and I have accomplished nothing."

"Not only that, but my life is also a mess. In order to take care of my seriously ill girlfriend, I gave up mathematics and tried to make as much money as possible, but in the end, I not only failed to save my girlfriend's life, but also wasted the time I could have spent with her. I really lost both ways and ended up with nothing."

"I'm already 27 years old this year, and I still haven't accomplished anything, and I have nothing. But... since meeting Lin Xian, I feel that all these previous failures, even if I fail all my life, don't matter at all."

He smiled and turned to look at Lin Xian. "Lin Xian told me that some things may be wrong a thousand times or ten thousand times. But it doesn't matter, it only needs to be right once at the most critical time."

"I still firmly believe in this sentence. I think this is something that only I can do in this world. Perhaps my life... exists for that moment, that second, that one time. Just that moment of glory is enough to dispel the haze of my entire life."

"So... little sister, I think your life may be the same."

Liu Feng looked at Chu Anqing's raised eyes. "Don't easily deny your value. It's just that the time hasn't come for you to play your role. Like I said just now, it doesn't matter if you're wrong for a lifetime. Some important things only need to be right once in a lifetime."

"In this world, there must be one thing that is prepared for you, born for you, and only you can do."

"Besides you... no one else will do!"
