Liu Song Hanque

Chapter 85
After Gao Yun woke up from the daze, he saw a big and round maid brutally slapping a towel with water on his face.

"Are you awake? Get up quickly! My aunt has never seen such a sleepy person!"

The maid's cursing voice made Gao Yun even more headache.

He sat up and thought for a long time before he remembered what had happened.

After spending a lot of effort to solve the problem, Liu Yizhen's new problem was the last straw that broke the camel's back.

Even now, Gao Yun still has lingering fears.

"How long have I slept?"

"One day and two nights! I can't even wake up!"

The maid looked a little arrogant towards Gao Yun, mainly because Gao Yun's previous image was no different from a beggar.

One day and two nights?
Gao Yun woke up instantly and ran out barefoot.

"Alas! Alas! Alas, where are you going? Stop!"

Gao Yun ran all the way to Liu Yizhen's mansion, already out of breath.

This time Liu Yizhen didn't make it difficult for Gao Yun, but let him in directly.

"Mr. Chang'an..."

"Sit down and eat first."

Liu Yizhen stirred a bowl of sweet porridge made from lotus seeds with a spoon, and asked Gao Yun to have a bowl of it by the way.

Gao Yun had no choice but to drink the porridge first, and the sweet taste refreshed him as soon as he ate it.

Desserts are the best refreshment for the brain, after Gao Yun drank the porridge, even the tiredness on his body dissipated a bit.

Soon Gao Yun finished a bowl, looking at Liu Yizhen who was still chewing slowly.

"Give him another bowl."

Gao Yun drank three bowls in a row before he burped in satisfaction, stretched his hands back, and looked up at the sky at a 45-degree angle like a salted fish.

"Gao Yun."

Liu Yizhen also finished his porridge at this time and came to Gao Yun.

"I have met Mr. Chang'an."

Gao Yun looked at Liu Yizhen's expression that seemed to be a smile but not a smile, and always felt that he was being molested.

But when he thought of Liu Yizhen's mathematical ability, Gao Yun still accepted his fate.

"It took you a week to calculate the problem I gave you, and you can be considered a genius."

Gao Yun smiled helplessly.

If someone else said this, he would probably take it as flattery, but what Liu Yizhen said, there was a sense of ridicule no matter what.

"But arithmetic is broad and profound, and the search up and down is endless. If you want to calculate everything, it is impossible."

Liu Yizhen took a book and put it in front of Gao Yun.

"The reason why I tell you this is that I hope you will always be in awe of knowledge. The way of heaven is unpredictable, don't miss the opportunity because of arrogance."

Although Gao Yun developed well in the later stage in history, he also became famous at a young age.But his middle age has been very difficult.

After he returned to vulgarity, he had been depressed and frustrated. In the good years of his life, no one was willing to reuse him, but he was just an official like meritorious service.

It was not until the age of 40 that Gao Yun was discovered by Tuoba Tao's uncle Du Chao, who appointed Gao Yun as the middle man, and Gao Yun entered Tuoba Tao's eyes, and has been on the rise since then.

But how many 40 years can one live?

It was precisely because of the ups and downs before that Gao Yun, the prime minister of the Northern Wei Dynasty, was created.

The current Gao Yun is still a bit arrogant about his talents, which may be a good thing for a writer, a poet, and a mathematician, but if he steps into an official career, Gao Yun will definitely be killed by his own pride.

That's why Liu Yizhen deliberately whipped Gao Yun's self-esteem as a warning.

Gao Yun was deeply touched when he heard Liu Yizhen's words.

"There are people beyond people, and there is sky beyond the sky. Gao Yun has remembered the lesson given by Lord Chang'an."

At the same time, Gao Yun looked at the book that Liu Yizhen placed in front of him.

"what is this?"

I saw four large characters—"Geometry Elements" written on the cover, which looked a bit mysterious.

"This is a mathematics book from a powerful civilization in the west of Tianzhu. I also got it by accident."

"Nine Chapters on Arithmetic"

"Euclid"

The cornerstone of Eastern and Western mathematics.

Mathematics is the basis of all natural sciences, so it is not wrong to call them the cornerstone of natural science.

The former is applied mathematics, and the latter is geometric mathematics.

The former is the practical art of mathematics compiled by Zhang Cang and Geng Shouchang, while the latter has the rigorous logic system and reasoning methods of Euclidean geometry.

The combination of the two, what kind of sparks will burst out in this relatively closed era?
Perhaps Gao Yun will give the answer.

Gao Yun took "Elements of Geometry" and flipped through the first page, but was confused by the contents.

Geometry and Algebra?
What do you mean?
But although the mathematical form is different, the thinking is not much different.

In addition, the questions Liu Yizhen gave Gao Yun before made him more and more comfortable with the use of numbers, so he can still understand after he calms down.

"How about it?"

After Gao Yun read it for a while, Liu Yizhen pulled Gao Yun out of the book.

"wonderful!"

Although the knowledge in the book is not difficult, a truly smart person will see the phenomenon clearly through the surface.

The way of thinking in "Elements of Geometry" is very different from that of Chinese civilization, which is the reason why Gao Yun called out "wonderful".

When Gao Yun was reading a book, it was as if he was traveling through time and space, communicating with an unprecedented philosopher.

"This book is for you."

Liu Yizhen's indifferent words made Gao Yun's throat tremble unconsciously.

Knowledge is wealth.

Now someone else has a rare book and wants to bury it in the ancestral grave. He is so frantic that he hopes that no one will know about it except himself, but Liu Yizhen is doing the opposite.

"Mr. Chang'an is serious? This book... is definitely worth ten thousand taels of gold, no! 10 taels!"

Gao Yun rolled his eyes.

I'll give you [-], you go to the West and bring me "Elementary Geometry" for a try?
Some things are priceless.

"Anyway, someone already owes me 10 taels of gold, so it doesn't matter if I owe another [-] taels?"

Gao Yun's face was flushed, and he looked a little ashamed.

Thinking about some of his previous actions, Gao Yun himself panicked with embarrassment.

"You study the knowledge in the book carefully, and I will still have it after I master it."

and also?

Gao Yun's eyes widened.

At this moment, like the previous monk guide and Wang Maide, he wished he could hug Liu Yizhen and kiss him.

What kind of Mr. Chang'an is this?It is simply a beast!

The difference is probably that the monk leader thinks that Liu Yizhen is proficient in Buddhism and is listening to the truth in hell, Wang Maide thinks that he is a brave man who can make money, and Gao Yun thinks that Liu Yizhen is the same as the legendary all-knowing Bai Ze.

Liu Yizhen felt a little scared by Gao Yun's eyes, and immediately told him to leave.

As soon as Gao Yun left, Du Ji came to the door.

"Do you regard my mansion as a government office?"

Liu Yi was really helpless. He contacted the boss during non-working hours, and the boss was also very angry.

Du Ji's face was solemn: "Mr. Chang'an, someone is here."

Seeing Du Ji's solemnity, Liu Yizhen also tensed up, thinking that something important had happened.

"Who? The court? Has something happened in the south?"

"No, it's the Messenger of Rouran."
