As a turtle pursuing truth, when I saw these ghost drawing talismans, there seemed to be a voice shouting loudly in my mind: It’s them! It’s them!

The truth of the universe! The truth of the universe is in front of you.

The white turtle "Xuanwu" was born in an extremely distant era. Most of the time of life, it was in a daze, just like an ordinary turtle, eating, drinking, urinating, and sleeping in the sun.

In the Yang River, after living for a long time, some miracles will always be born.

Because of some unknown reasons, "Xuanwu" ignorantly gave birth to his own wisdom.

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

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

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

But there are also a small part of the world where humans live completely.

Until one day, it came to the vicinity of an ancient civilization.

It was such a strange country. It was obviously very weak, but it seemed to be loved by heaven and earth and not invaded by disasters.

In this small island country, many mathematicians, philosophers and private people were born.

Xuanwu lived in that country for 20 years. Because he was too beautiful, he was raised as a divine beast. The person responsible for teaching it was a great sage. Under the sage's earnest sage, Xuanwu learned the existence of the 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 the truth will last forever!"

Unfortunately, disaster broke out and weak countries were invaded by powerful enemies.

At that time, Xuanwu was just a little turtle and had no ability to stop the destruction of the world. Although it had given birth to initial wisdom, it was only initial and ignorant.

And when the enemy was out of power and his life entered the countdown, the sage sat next to the broken stone wall and was drawing a geometric figure on the sand. A monster was approaching, and he made a proud gesture and said: "Go away, don't move my truth!"

The monster did not know the truth of human beings, so he rushed forward frantically and bit the ancient sage to death.

This scene will never be forgotten by Xuanwu.

It is not just the death of the sage.

Everyone has a day of death, the world is shattered, and the sage is ready to die.

Even its Xuanwu will eventually die one day.

What it feels most about is the determination of the sage to pursue the truth before his death...

Truth, truth, how many geniuses have been for it, just to seek the ultimate truth!

So Xuanwu once again began to travel the world.

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

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

Some people start from the experience level, while others think that truth is "awe".

The cow is the incarnation of the gods. As long as you understand everything about the cow, 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.

Some people answered from a philosophical level that "truth was born after a hundred question marks" is very dissatisfied.

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

"Without human existence, the existence of the world is meaningless."

All in all, these answers are not satisfied with it!

As for the giant tortoise civilization's answer, "I don't know."

This answer is also very common. I don’t know, but I don’t know. Xuanwu is not so easy to fool.

But at this moment, it heard an unprecedented hardcore answer!

“Mathematics and Physics!”

Xuanwu is not so easy to fool. Its inherent spiritual sense allows it to see through a large number of liars. It is not just a casual ghost-drawing talisman that can satisfy it.

However, what is placed in front of it is a large number of top scientists. After hundreds of years of exploration, no matter how it perceives it, it believes that this is a sincere answer!

Moreover, influenced by the first sage from the bottom of his heart, Xuanwu also likes mathematics and worships mathematical theorems.

Mathematics is based on logic thinking. It cannot be true or false. Everyone can study it and everyone can achieve results.

It won't lie!

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

"I sincerely hope that this avenue is smooth..."

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

When asked this question, Xuanwu seemed a little nervous.

It has no other hobbies in its life, so it likes to calculate numbers and divine the secrets of heaven.

Its life cycle is too long, witnessing the prosperity and decline of countless civilizations, and is used to separation from life and death.

A child grew up and grew up when he woke up and reproduced the next generation. When he woke up, the former teenager was already old. Looking back on the past, he found that time passed and he accomplished nothing, so he told Xuanwu about his lifelong experience.

Love, hate, love, sweetness, bitterness, and other people's feelings are like drinking water, and you will know the warmth and coldness of others.

Therefore, it is quite cold to the warmth and coldness of the world, and if you see more, it will naturally become weak. Humans are smart species, but because their lifespan is too short, many people are pursuing some boring pursuits.

But mathematics is different. Right is right, wrong is wrong, and you can think about it 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 among their group.

When talking about the mathematical laws he invented, Xuanwu became unexpectedly talkative: "Old turtle, I invented the method of tortoise shell divination, and a large part of it was to use mathematical principles: the sixteen grid!"

Xuanwu spit out a column of water from his mouth, drew sixteen grids on the ground, and filled the sixteen numbers 1-16 into it. Each horizontal, vertical, and diagonal numbers are equal.

"Above the sixteenth square, there are twenty-five squares, thirty-six squares, and forty-nine squares, which seem to be endless and counted! But the ninety-nine eighty-one squares can't be put together, and no one can discuss them, it's a pity!"

The old turtle was very 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 Country... they have long been lost in previous disasters.

There are no mathematicians in the Giant Turtle Country. If mathematics is enough, how can mathematicians 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 turtle's wisdom level.

Sixteen grids? Isn’t this the primary school mathematics mathematics?

Lu Yiming had learned it before, and it had a better name called "如果有". According to the current saying, it is not of much value, so it is done with computer violence.

Well, a turtle invented the Sixteenth Grid without anyone’s guidance. Maybe it’s also a genius?

He wanted to laugh a little, shook his head again, and said, "To be honest, it's not that I'm too stingy and don't impart knowledge to you. But... there are too many books in this area, so many that you can't imagine! Your room here is very big, but even if it expands ten times, you can't put down all the books."

"There are many physical books that can be found in the Central Library of the Sea of ​​Clouds. Our National Library has no more than one thousandth of my total civilized knowledge."

"Most of the books are stored in the form of data in the central computer, and can be learned through distance education... In this way, we can give you a set of primary, middle school, university and undergraduate textbooks. You can take a look first. Oh, by the way, I will give you some Olympiad selections for primary and secondary schools, as well as CMO and IMO's past real questions."

"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 specially transported a batch of books from the Sea of ​​Clouds, which took 20 minutes.

Facing the fresh books, Xuanwu started reading them with relish. Some of the above knowledge has been learned, while others are very fresh and interesting.

So, after seeing Xuanwu, this time the security inspection was basically completed, and the giant turtle civilization finally ushered in its brand new hometown... a piece of its own island!

In the next few months, we would be at peace. Since the Yang River was in a state of darkness, several small-scale monster invasions appeared, all of which were blocked by the joint army without any danger.

The giant turtle civilization is a very cohesive race, and the people's living conditions are quite rich. In addition to the slight chaos at the beginning, they have also slowly gained a foothold in this world... Of course, the main reason is that the sea of ​​clouds did not deliberately dump or deliberately invade culturally.

As long as the capital of the Sea of ​​Clouds is doing its own well, it is enough, and there is no need to make targeted actions.

Otherwise, no matter how powerful the giant tortoise civilization is, it will not be able to withstand the dumping behavior of mature industrial countries.
Chapter completed!
