In the fantasy realm of ten thousand immortals, the two peaks are far away from each other.

"Master, I still don't understand what you mean. ”

Facing Feng Luoyi's whispered inquiry, the master Xi Baiche looked absent-minded: "What?"

He looks weird.

"Ten Thousand Laws Count the Collection" is the painstaking effort of him and the entire Geting faction. Then, for him, the beginning of the first volume of "Ten Thousand Laws Counting" should also be a happy event in life that is equivalent to the title of the gold list.

But now, this great arithmetic, a generation of carefree overhauls, does not have the slightest sense of joy.

On the contrary, his face was full of tiredness and confusion, as if he had experienced a long journey, but did not know why he did not see the scenery he wanted to see.

Feng Luoyi even felt that the old master's face was a little older.

It's not normal. It's not normal. The guy in front of him is not at all like the twenty-three masters who ask the world's arithmetic.

So, he asked: "Those 500 pages are the direction of your work, but they are definitely not your usual style. ”

"'Those five hundred pages'......" Xi Baiche smiled bitterly, "is that the five hundred pages that talk about 'one plus one'?"

"I thought you didn't like those things. ”

Although Wanfamen can be roughly divided into two schools of thought, "Lizong" and "Lianzong", it is not a monolith within the school of thought. There are even finer divisions in it.

The Geting faction is the representative of the sect, but it does not mean that there is only the Geting faction.

Wang Qi once used the "sword qi dispute" in "Smiling Proud Jianghu" to compare the arithmetic disagreement of Wanfamen. In that earth novel, the representative of Huashan Qi Sect is Zixia Gong, but many readers automatically ignore it. In fact, Huashan Qi Sect has another representative of the peerless school. Mixed Yuan True Qi. This is because Zixia Gong's role in that novel is too heavy.

It's pretty much the same. The master of the calculator is the bull's ear of the arithmetic. The Geting he represents has naturally become a representative of the sect, and other ideas belong to the "edges".

And now, Hebencher actually uses a very marginal way of thinking?

This is as incredible as the dignified Shaolin faction head who does not practice the Yijin Sutra, but instead uses Luohan Boxing as his main practice!

"I've done this kind of thing before, right?" Xi Boche smiled bitterly: "Forced by the situation, I temporarily agreed with the ideas I don't like." ”

Feng Luoyi knew what Xi Baiche was referring to. About six years ago. In order to deal with the Lianzong led by the Emperor Pang Jialai, Xi Baiche and the entire Geting faction temporarily adopted Wang Qi's idea of being able to produce results in a short period of time, which is the idea of the so-called "Bourbaki School" on the earth.

Hebencher doesn't fully agree with this idea. But due to the situation, he accepted it for the time being.

Feng Luoyi was puzzled and asked, "Who can force you?"

"No one can push me. Hepeche shook his head: "I'm forcing myself. ”

"What?"

"Yue Han, do you know?" Xi Baiche called his old friend in Feng Luoyi's expression: "Arithmetic, how great, how incredible. All I'm doing now is looking for a way, a path that will lead us to the 'Great Way.' ”

"But it's just a way to go. I'm already exhausted. ”

Feng Luoyi sighed: "This topic...... It's really hard to understand. ”

If we say, science uses mathematics as a tool. Summarizing the laws of all things and pushing them from the known to the unknown, what Hebrache is doing now is to use mathematics itself as a tool to summarize the laws of mathematics itself, and to infer the unknown parts of mathematics from the known parts of mathematics. That is, "the mathematics of studying mathematics", or "metamathematics".

In this world, it is called "Yuan Shudao".

If we can use mathematics as a tool to study all things, then what kind of "mathematics" should we use as a tool to study mathematics?

Is there a "branch" that can be used to exhaust the trunk in turn?

The master Xi Baiche is facing such a problem.

"I still don't understand, Sect Master, you're not the kind of person who can change your mind in just a few years, and ......" Feng Luoyi paused for a moment, and then asked, "Who wrote those five hundred pages?" I asked all the fellow Daoists, it wasn't written by any of them, and you don't have time to write about it. ”

Xi Baiche smiled: "Yue Han, you won't forget, right? Time is a thing that is very 'personal' for people in your and me's realm. ”

Feng Luoyi suddenly felt a shudder.

Many people have the impression that time is absolutely equal to every object. But that's just that they don't look far enough. If we look at the level of celestial bodies, then time is really just a regional thing.

The strength of the immortals varies. If you are weak, you will be several times as strong as Mahayana, and if you are strong, you will be stronger than ordinary celestial bodies. The presumed Enlightening Celestial Body is only the strongest among the immortals, not the strongest in theory.

For the strong among the immortals, "personal time" and "personalized time" are just natural concepts. Whether it is a hundred years or a thousand years, it is only in their thoughts.

In this case, "society" naturally becomes an impossible thing to achieve.

Feng Luoyi asked, "How much time have you created for yourself?"

The calculator shook his head: "I don't remember." How can you possibly remember this? Probably...... Ten years or so?"

Feng Luoyi breathed a sigh of relief. Ten years, fortunately, it is still within the acceptable range.

If it is because of a long period of solitary retreat that Xi Baiche's mind has reached a dead end, it will be a loss for the entire Shenzhou.

Xi Baiche sighed: "In those times, I thought alone, looked for a way to break the game, and proved myself again and again to overthrow myself again and again. Eventually, I seemed to realize that this was not going to work. I'm nowhere near as smart as I thought I was. Maybe I should start with some of the basics......"

Feng Luoyi frowned: "The most basic? That's it...... Stupid argument?"

"I'm counting on the 'way out' in there. ”

"Actually?"

Xi Baiche sighed: "I haven't found it yet. These arguments, even from my own point of view, are ......"

"It's chaotic, nothing is clear. Feng Luoyi criticized mercilessly.

He shook his head: "At least I'm ...... in gauge set theory itself," but he found that his old friend's expression was a little puzzled and ...... Wrath?

And not against him?

What's going on?

Wang Qi stretched out his hand and swiped his index finger across the straight line on the ground: "Do you still remember the concepts of points, straight lines, angles, perpendicular, parallel, and painting the sky that I talked to you about yesterday?"

Gou Dabao nodded, and there was already a bit of "piety" in his eyes.

Today is the fourth day of the teaching. On the second and third days, Wang Qi taught Gou Dabao all the basic concepts of geometry. Now, he can pat his chest and guarantee that this fairy already has geometry attainments at the level of about the sixth grade of primary school, and can even skip the level and compete with ordinary students in the first semester of junior high school, and if he encounters a junior high school scumbag, he can even achieve the effect of sweeping!

Just to achieve this effect, Wang Qi wasted two days.

"What about Roche geometry and Ryche geometry?"

"Sir, that's too difficult, I only know a little bit about it, but I don't know it at all......"

Gou Dabao's words can already be called "reverence". For some reason, he now has a feeling of admiration for Wang Qi, and he has long since lost the cold words of a few days ago.

For him, Wang Qi was the one who gave him a new luster in life. This guy, who was less than half his age, opened a window to a whole new realm for him.

"It's good to know about it. Today, I will tell you the truth of 'different paths to the same end' in arithmetic, which can be regarded as further explaining to you that 'arithmetic' has its own freedom, is close to the Tao, or is itself a Taoist thing. ”

Wang Qi did not ask Gou Dabao to master anything. In the final analysis, his purpose is not to let this immortal master anything, but to let Gou Dabao understand mathematics, no longer reject mathematics, solve his spiritual problems, and make him less obstacle to cultivating the Ten Thousand Methods.

For Wang Qi, this process is also a process for him to temporarily stop and sort out his own concepts. This process did not help his academic level in any way, but it could improve his spiritual cultivation and make him grasp and feel more deeply about arithmetic.

As the saying goes, sharpening knives does not mistake woodcutters. Wang Qi did not do him any good now, but it may not be a help for his future cultivation.

"Gou Dabao, you must have noticed it too, right? The geometry of the human race first had Euclidean geometry and the method of drawing the sky, and then there was the geometry of Li and Luo. The existing curvature is zero, and then there is a positive curvature and a negative curvature, right?"

Gou Dabao nodded: "Yes." ”

"Do you think, then, that this is the only right way to develop geometry?"

Gou Dabao shook his head suspiciously: "The disciple really doesn't understand, how can there be another way other way......

Wang Qi asked rhetorically: "In your eyes, the world is straight, isn't it?"

Gou Dabao wanted to say "Isn't this nonsense", although his immortal remnant soul faintly transmitted some concepts, which made him feel that this statement was not reliable, but the immortals themselves did not have a clear concept of bent time and space, they were just because their own existence was too great, so they did not need the tool of mathematics to directly observe space, that's all, so Gou Dabao couldn't say why. In the end, he could only nod: "Yes"

"So. If I tell you. There are other races in this universe who have a completely different concept of space from the human race, but eventually reach a similar state, do you believe it?" )
