The world enters the age of myth

As a turtle who pursues the truth, when I see these ghostly symbols, there seems to be a voice shouting loudly in my mind: It’s them! That's it!

The truth of the universe! The truth of the universe is before your eyes.

The white turtle "Xuanwu" was born in an extremely distant era. For most of its life, it was in a muddleheaded state, just like an ordinary turtle, eating, drinking, basking in the sun, and sleeping.

In Yanghe, if you live for a long time, some miracles will always happen.

For some unknown reason, "Xuanwu" ignorantly gave birth to his own wisdom.

The tortoise shell on its body sprouted mysterious and complex pictures and texts. With the help of these pictures and texts, it mastered the weak supernatural power and survived in the chaotic environment.

It began to travel around the world and visited various parallel universes on the Yang River.

Most of the world is full of broken mountains and rivers, with not even a single living person left.

But there are also a small part of the world where humans fully survive.

Until one day, it came near an ancient civilization.

It is really a strange country. Although it is very weak, it seems to be loved by heaven and earth and has not been invaded by disasters.

In this small island nation, many mathematicians, philosophers and private individuals were born.

Xuanwu lived in that country for a full 20 years. Because he was so beautiful, he was raised as a mythical beast. The person responsible for teaching it was a great sage. Under the sage's earnest guidance, Xuanwu understood the existence of truth for the first time.

"Truth is the way the world works!"

"The rules of operation of the world are the truth!"

"There is no God in the world! Even if there is, God will die! Only truth will last forever!"

Unfortunately, disaster broke out and the weak country was invaded by a powerful enemy.

At that time, Xuanwu was just a little turtle, unable to prevent the destruction of the world. Although it gave birth to preliminary wisdom, it was only preliminary and ignorant.

And when the enemy was overwhelming and life was counting down, the sage sat next to the incomplete stone wall and was drawing a geometric figure on the sand. A monster was approaching. He gestured arrogantly and said, "Go away and leave my truth alone!"

The monster didn't know the truth about human beings, so it rushed forward crazily and bit the ancient sage to death.

This scene will never be forgotten by Xuanwu.

What it laments is not just the death of the sage.

Everyone has to die one day, the world is shattered, and the sage is ready to die.

Even Xuanwu will eventually die one day.

The most touching thing about it is the determination of the sage to pursue the truth even before his death...

Truth, truth, how many geniuses have fought for it, just trying to get to the final truth!

Thus, Xuanwu once again began the process of traveling around the world.

This question has been asked by many civilizations in the long past. Because the appearance is almost perfect, it can be regarded as a mythical beast every time and is enshrined by major civilizations.

"What is truth?" Xuanwu would ask them this question.

Some people start from the experience level, and some people think that truth is "cow".

Cows are the incarnation of gods. As long as you understand everything about cows, including cow dung and cow urine, you can grasp the true meaning of the truth. Drink some cow urine when you are sick and the cow will tell you all the truth.

There are answers from the philosophical level. The inexplicable sophistry of "truth is born after a hundred question marks" is very unsatisfactory.

There is also an explanation about art: "There is truth in art. Because art is the embodiment of human spirit and the perception and understanding of transcendent existence. Therefore, what is truly displayed in works of art is not just an object. The real world is composed of content, but human emotions.”

"Without the existence of people, the existence of the world has no meaning."

All in all, I am not satisfied with these answers!

As for the giant turtle civilization, the answer is, "I don't know."

This answer is also very common. If you don't know, you just don't know. Xuanwu is not so easy to fool.

However, at this moment, it heard an unprecedented hard-core answer!

"Math and Physics!"

Xuanwu is not so easily deceived. Its inherent spiritual sense has allowed it to see through a large number of liars. It is not just a random talisman that can satisfy it.

However, placed in front of it are a large number of top scientists and hundreds of years of exploration. No matter how it perceives it, it thinks this is a sincere answer!

Moreover, deeply influenced by the first sage, Xuanwu also liked mathematics and worshiped mathematical theorems.

Mathematics is based on logical thinking. What is true cannot be false, and what is false cannot be true. Everyone can study it and everyone can make achievements.

It doesn't lie!

"This answer is very good. Dear scientific and technological civilization, it seems that you have identified this path."

"I also sincerely hope that this road will be smooth..."

The old turtle opened his mouth and seemed to laugh, "I have another request here. Can you give me a copy of your civilization's knowledge? I also like mathematics knowledge very much, but it is a pity that the mathematics of the giant turtle civilization There are too few books. I looked over and over, but there was not enough to read."

When asked this question, Xuanwu seemed a little nervous.

It has no other hobbies in this life, it just likes to calculate numbers and divine fortune-telling.

Its life cycle is too long, it has witnessed the rise and fall of countless civilizations, and is used to seeing life and death.

A child wakes up and grows up to produce the next generation; when he wakes up again, the former boy is already old. Looking back on the past, he realized that time had passed and he had accomplished nothing, so he told Xuanwu about his life's experiences.

Love, hate, ups and downs, other people's feelings are like people drinking water, knowing whether it is warm or cold.

Therefore, it has a rather indifferent view of the warmth and warmth of the human world, and it will naturally become indifferent as it sees more. Humans are an intelligent species, but their life span is too short, and many people are pursuing boring pursuits.

But mathematics is different. Right is right and wrong is wrong. It can be pondered over for a long time. Every step forward on this path is equivalent to eternal progress.

Lu Yiming seemed a little nervous. There were no mathematicians in their group.

Talking about the mathematical laws he invented, Xuanwu became more talkative than expected: "Old Turtle, I invented the turtle shell divination method, and a large part of it is based on the mathematical principle: the Sixteenth Palace Grid!"

Xuanwu spit out a column of water from his mouth, drew a sixteenth grid on the ground, and filled in the sixteen numbers 1-16. Every horizontal, vertical, and diagonal number was equal.

"On top of the sixteen palace grids, there are twenty-five palace grids, thirty-six palace grids, and forty-nine palace grids. It seems that it can be endless, and it goes on and on! But what about the ninety-nine and eighty-one palace grids? We can’t even come up with it, and there’s no one to discuss it with, what a pity!”

The old turtle was extremely proud of his mathematical invention.

After all, it usually stays in this small room, and no one talks to it. As for the documents of the Giant Turtle Kingdom... they have been lost in previous disasters.

There are no mathematicians in the Giant Turtle Kingdom. Mathematics is enough. How could a mathematician appear in this environment?

So it can only entertain itself like this all day long.

Lu Yiming was also stunned for a moment, and had a rough understanding of the intelligence level of this turtle.

Sixteenth square? Isn’t this a primary school math olympiad?

Lu Yiming had learned it before. It has a better name - "Magic Square". According to the current theory, it is not of much value. Just use computer brute force to solve it.

Well, a turtle invented the sixteen-square grid without any guidance, maybe it is also a genius?

He wanted to laugh a little, then shook his head and said: "To tell you the truth, it's not that I'm too stingy to pass on my knowledge to you. It's just that... there are too many books on this subject, more than you can imagine! You are here The room is very big, but even if it were enlarged ten times, it still wouldn’t be able to fit all the books.”

"There are many physical books that are unique. They can be found in the Central Library of the City of Clouds. And the total number of books in our National Library does not exceed one thousandth of the total knowledge of our civilization."

"Most of the books are stored in the central computer in the form of data and can be learned through distance education... Well, we can send you a set of textbooks for primary school, middle school, and university undergraduates. You can first Take a look. Oh, by the way, I’ll give you some selections from the Mathematical Olympiad for primary and secondary schools, as well as past papers from CMO and IMO.”

"If you are interested, you can do the exercises inside."

Lu Yiming said a few words to a subordinate. Soon, the anti-gravity plane took off vertically and transported a batch of books from the Capital of Clouds, which took 20 minutes.

Facing the fresh books, Xuanwu read them with relish. Some of the above knowledge has already been learned, and some of it is new and interesting.

So, having seen Xuanwu, this time the safety inspection was basically completed, and the Giant Turtle Civilization finally welcomed its new hometown...an island of its own!

The next few months will be peaceful. Since it was dark in the Yang River, there were several small-scale monster invasion waves, but they were all blocked by the combined army without any danger.

The Giant Turtle Civilization is a fairly cohesive race, and the people's living conditions are relatively prosperous. Apart from the slight chaos at the beginning, they have slowly established a foothold in this world... Of course, the main reason is because, the City of Clouds There is no deliberate dumping or deliberate cultural invasion.

It is enough for the City of Clouds to do its own development, and there is no need to make targeted moves.

Otherwise, no matter how powerful the giant turtle civilization is, it will not be able to resist the dumping behavior of mature industrial countries.

There are also a small number of people who go to the City of Clouds to work. This is understandable and inevitable.
