Lin Xian put away his smile.

He looked at the trash can at his feet:

"What do you mean?"

"This is my analysis, Lin Xian." The trash can robot VV rotated its tracks, circling around Lin Xian... This action was clearly imitating Lin Xian's pacing in place just now:

"A mirror itself is a very simple, very pure thing without any deep meaning. If, as you said, that woman sincerely wanted to help you, she would definitely try her best to make the hints obvious enough, understandable enough, enough for you to grasp…"

"On the contrary, I think you're overthinking it, you know? There's a good saying in a famous science fiction novel—often, we can't find the answer, not because we're not thinking complex enough, but because we're not thinking simple enough."

"Just like the mirror riddle that woman gave you, if you think about it in a complicated way, it's simply endless. I just used all my computing power, constantly extending and expanding… I even considered the impact of mirrors on the speed of light, but obviously, these are meaningless. If she wanted to hint at other things, she could have used a more appropriate hint. There's no need to lead you to mirrors."

"Again, if she really wants to help you, sincerely wants you to quickly understand her hint, she will do everything possible to make the puzzle as simple as possible, not as complicated as you think, giving you a headache, making you guess, making you unable to find the answer… Isn't that putting the cart before the horse?"

…

VV's words left Lin Xian speechless.

Truly speechless.

VV's point was that this woman would never deliberately make things difficult for him. Since she said it was a mirror, it must be a mirror; since she told him to look in the mirror more, then he should listen to her and look in the mirror more.

The reason he was so confused and clueless was:

Not because he wasn't thinking complex enough, but because he wasn't thinking simple enough.

Profoundly baffling.

"So…"

Lin Xian said:

"You still think I spend too little time looking in the mirror every day? I should just understand that woman's words literally and look in the mirror more, is that right?"

The trash can robot nodded:

"According to my analysis, this is the most reasonable. Just like me, even though my underlying code is restricted by the Three Laws of Robotics, I still won't give you a hazy answer on many issues. As long as it's determined that we are friends, not enemies, then the goal is definitely to help you, not to make things difficult for you."

"I think you're overthinking things. Why not simplify the problem and just do what she said? Or… since she mentioned waiting for you at the Jiuquan Satellite Launch Center, is that specific hint the prerequisite for the mirror riddle?"

"So, if you can't find any answers from the mirror hint for the time being, why not follow the route planned by this woman, first solve the outer space coordinate point, reference object, and the things she prepared for you at the Jiuquan Satellite Launch Center. Perhaps after that, the answer to the mirror riddle will be obvious."

"Of course, I still have to advise you, the information you provided to me is only what you think is correct, not necessarily the real correct. My reasoning is based on the assumption that the woman is indeed a time traveler, she certainly won't harm you, and you are accomplices, and assuming that everything she said is true… If the information you provided is incorrect, then the answer I give will also inevitably be inaccurate."

Lin Xian thought for a while.

He nodded.

VV's analysis made sense.

Taking a roundabout route might not be a bad idea.

He was too concerned about the answer to the mirror riddle, but the most direct purpose of Huang Que's appearance in Liu Feng's laboratory at that time was actually for the cosmic constant, the time clock, the space-time curvature, and the space-time reference object coordinates.

The note she deliberately left behind may be the real key.

"Well, when I have time in a few days, I'll go to the laboratory of Donghai University to chat with Liu Feng and see if his research results have made any breakthroughs."

After saying that, Lin Xian sat back in his chair and faced the electronic blackboard.

"Are you going to start memorizing the code now, Lin Xian? Hurry up, I can't wait to see you in the world 600 years ago."

The trash can robot VV waved its mechanical claws, and the nurse robot, which had been waiting for a long time, walked towards Lin Xian's neck with a syringe.

"No, wait a minute today. There's something else."

Lin Xian smiled slightly:

"The day after tomorrow is the day when Donghai City officially holds an commendation meeting for me. I also have to give a speech on stage, which will be broadcast simultaneously on the Internet, Donghai TV, and in the classrooms of major primary and secondary schools. It's a pity that I've been busy with other things during this time and haven't had time to write a speech."

"So… before memorizing the code today, VV, please write a speech for the commendation meeting for me first."

"Huh?"

The trash can robot let out a mechanical broken sound.

It put its two mechanical claws on its hips, very unconvinced:

"Please! I am the greatest artificial intelligence in human history! The most brilliant pearl in the history of human scientific development! The secret weapon left to human civilization by the respected Ms. Zhao Yingjun!"

"Just like you said just now, I'm boiling with enthusiasm. Such a great existence like me should be doing big things like traveling through time and space, saving the world, and cracking the secrets of the universe! You actually want me to write a primary school student's composition for you?"

"You don't understand anything."

Lin Xian slammed his hand on the trash can's crown, stopping it from tiptoeing:

"Writing papers is the correct way to use artificial intelligence. Speed."

Although VV was unconvinced.

But after all, Lin Xian was its owner, the existence with the highest authority in the entire Rhein Sky City. It obediently used less than 0.0000001 seconds to generate a commendation meeting speech, which was displayed on the electronic blackboard.

Lin Xian watched with relish:

"Well, good writing."

"Does memorizing this speech require taking drugs to boost your performance?" VV asked.

It was very good at imitating and was very curious about the words and deeds of Lin Xian, this old-era ghost, and always blindly imitated.

"This is definitely not necessary." Lin Xian shook his head:

"This kind of speech doesn't need to be memorized by rote at all. Just look at it once and understand the structure and ideas. If your code had the same logic and grammar as the speech, I might have memorized it all in less than a month."

"Actually, there are still common points… It's just that you're too stupid. If you replace me with a qualified programmer, it would definitely be more efficient than you taking drugs to boost your performance." VV complained.

After reading this speech for half an hour, Lin Xian had almost memorized it by heart. After going out, he could imitate it and write it down in his own words.

In this way, the commendation meeting the day after tomorrow would be resolved.

This was a speech that the people of the whole city were paying attention to, so he couldn't drop the ball and lose face.

"Okay, I've finished reading it."

Lin Xian tilted his neck and pulled down his collar:

"VV, give me the drugs!"

…

In the following days, Lin Xian was like this, transforming into an emotionless, performance-enhancing, memorizing, human copying machine.

With the blessing of excessive drug injections, his memory exploded in a short period of time, and he could memorize at least 500 lines of code every night.

Especially after getting through the hexadecimal gibberish of the first two days, those pure code composed of English words became much easier to memorize.

As he became familiar with these code languages, Lin Xian's efficiency in memorizing code became faster and faster. Sometimes, if the code was simpler, he could memorize 700 or 800 lines a day.

He believed that this number would get higher and higher.

On the one hand, under the guidance of VV, his understanding of the logic of programming languages was getting deeper and deeper, and the pressure on his memory was also getting smaller and smaller.

On the other hand, VV's code was really beautiful.

Concise as poetry.

It was worthy of being called the most brilliant technological pearl in human history. The beauty of its code alone was worthy of this self-proclaimed title.

When memorizing this wonderful, poetry-like code, Lin Xian also thought of what Li Qiqi once said…

She said she didn't understand mathematics, but she understood art.

Liu Feng's Introduction to Cosmic Constants was beautiful to read and beautiful to look at, so this theory couldn't be wrong.

"Because the universe itself is beautiful."

Lin Xian also agreed with this sentence.

He was even more convinced than anyone else that Liu Feng's Introduction to Cosmic Constants must be correct.

Or rather…

Someday.

It will be correct!

…

The next day.

After Lin Xian got up, he found a WeChat message from Liu Feng:

"Lin Xian! Come to the lab when you have time! There's been progress in the research!"

He yawned and sat up.

From these three exclamation points, it was not difficult to see Liu Feng's excitement.

Lin Xian also felt it was a coincidence.

He said last night that he would find time to visit Liu Feng, and it was like speaking of Cao Cao, and Cao Cao arrived.

After replying with an OK gesture, Lin Xian got up to wash up and prepared to go to Donghai University.

His personal driver was waiting downstairs early.

The electric door of the business car opened, and after Lin Xian got in, it turned and drove towards Donghai University, Rhein Joint Laboratory.

"Tell me, what's the breakthrough in the research?"

As soon as he entered the laboratory, Lin Xian went straight to the topic.

He saw the unremarkable Time Clock on the experimental table at a glance.

He picked it up and took a look.

The numbers on it still hadn't changed:

0.0000000

Eight zeros.

In fact, he was still looking forward to it.

If one day, as Huang Que said, Liu Feng found the reference coordinate system outside this time-space and calibrated this Time Clock to zero…

When the time-space changes again and the time-space butterfly effect occurs, how will the numbers on this change?

What will the space-time curvature be?

Will it be related to the cosmic constant?

Sometimes, when you think about it carefully, scientific research is really an interesting thing. Especially this kind of topic that is ahead of current scientific knowledge, it is indeed both curious and fulfilling.

Liu Feng stood up from in front of the experimental equipment, pushed his glasses, and walked towards Lin Xian:

"Lin Xian, I think I've found a way to discover that outer space-time reference object."

"How do you say that?"

Lin Xian pulled up a chair and sat down, looking at Liu Feng.

"It's like this, Lin Xian, let me give you an example first."

Liu Feng also pulled up a chair and sat opposite Lin Xian:

"You must have heard the saying that there is no wall that doesn't leak, right?"

"Of course."

"Although conventionally speaking, walls are definitely airtight, this proverb illustrates a truth, that is, there is no absolutely impenetrable wall, no barrier that can completely prevent everything from passing through."

Liu Feng pursed his lips:

"For example, water cannot pass through plastic bags, but oil can! Plastic bags are generally made of polyvinyl chloride molecules, and there are gaps between the molecules. As long as the object is shorter than the length of the molecular gap, it can easily pass through the plastic bag."

"Of course I understand this."

Lin Xian gestured for Liu Feng to fast forward:

"What you want to express is that there will always be things smaller than the molecular spacing, atomic spacing, and even the atomic nuclear spacing that can pass through the smallest of gaps. Just as you told me last time about the Planck constant, the universe itself is discontinuous, and it also has the shortest gap length, which is the Planck length. You can continue to talk about this concept."

"That's right, that's what I mean!"

Liu Feng gave Lin Xian a thumbs up like he was coaxing a primary school student:

"So I boldly conclude—"

"Time-space itself is not a wall without gaps!"

"If there really is space-time curvature, different time-spaces, and different world lines. Then between these different time-spaces, there must also be walls similar to the existence of preventing all time-space matter from communicating and crossing."

"However, there is no absolutely airtight wall! If the smallest gap in the time-space wall is the same as the smallest gap in the universe, which is the Planck length. Then if, in a certain space-time curvature, the Planck length of that time-space is smaller than the Planck length of our time-space… Do you know what will happen? It's obvious—"

"The microscopic particles of another time-space may pass through the Planck gap in the time-space wall and cross into our time-space!"

…

Lin Xian listened to Liu Feng's description.

He picked up the water glass on the experimental table and took a tactical sip of water.

Although it sounded a bit outrageous, theoretically speaking, this theory made sense.

Since our universe is not continuous and has a minimum Planck length, why must time-space itself be continuous? The time-space walls between different time-spaces may really have similar Planck gaps, the existence of this minimum length gap.

When Liu Feng was making the Time Clock, he had already assumed that the Planck constant, Planck length, and Planck time of different time-spaces have extremely small differences.

If all his assumptions are correct…

Then it may not be impossible for a certain length smaller than the current time-space, from other time-space microscopic particles, through the Planck gap on the time-space wall, to penetrate from another time-space into the current time-space.

"I roughly understand."

Lin Xian put down the water glass:

"This set of theoretical system is established on the premise that all your guesses and assumptions are correct, and it can indeed be self-consistent. The difficulty lies in how we should prove it and find it. According to your statement, the length of that microscopic particle is even smaller than the Planck length of our current time-space and current universe… How can we possibly find it?"

Liu Feng smiled, stretched out his arms, and looked around the laboratory:

"Lin Xian, isn't everything in our world made up of the most primitive and basic microscopic particles? If only a single outer space-time microscopic particle penetrates, we certainly can't find it."

"But when you find a cockroach, your house must already be full of cockroaches. I believe that there must be a certain number of these particles, and because of their own properties, they will definitely aggregate and combine together. In this way, it will be much easier for us to observe, and even…"

"We can capture it!"

Liu Feng pushed his glasses, his eyes firm and full of confidence:

"If you don't mind, I would like to call this special particle from outer space-time—"

"Space-Time Particle!"

Lin Xian couldn't help but be amused.

Is this a common problem of scientists?

They always like to name the things they invent, and it seems like they have their own set of naming standards.

Just like Liu Feng, he is just hung up on time-space, no matter what he names, he must add a time-space prefix.

However, it is indeed very appropriate.

"Liu Feng… you still didn't understand what I meant."

Lin Xian shook his head with a smile:

"I have no objection to you naming this particle space-time particle, I don't even object to you naming it Liu Feng particle. But the main problem is… does it really exist? Is your theory really correct?"

"Forgive me for speaking frankly, I will definitely unconditionally support your research, but we can't always shoot arrows in the air without hitting the target. I am very happy that your research has made breakthroughs, but the most important thing at the moment is that we must find this space-time particle… and then… can we calibrate your Time Clock and observe the changes in space-time curvature."

"Yes."

Liu Feng nodded:

"So, Lin Xian, that's why I called you here today. The equipment in the laboratory is no longer sufficient to support my continued research. I need new equipment."

"Of course, that's no problem."

Lin Xian picked up the pen on the table and twirled it between his fingers:

"Buying equipment is not a difficult thing. The company still has a lot of money now. Tell me, what equipment do you need? I'll buy it for you directly."

"Guizhou Tianyan."

Liu Feng replied.

Clatter—

The spinning water pen flew away from Lin Xian's fingertips, drawing a parabola and falling on the ground.

The entire laboratory was silent.

Lin Xian's hand twirling the pen froze on the table, looking at Liu Feng:

"What did you say?"

"Gui, zhou, Tian, yan."

Liu Feng said word by word:

"That is… the spherical radio telescope located in the mountains of southern Guizhou Province, with a diameter of more than 500 meters, the largest in the world—"

"Guizhou Tianyan!"
