Hu Yuan did not stop to rest, and hurriedly summarized his gains for the day.

The various circumstances in the wounded barracks, as well as the sound of thanks and the praise of the miracle doctor, all made him a little at a loss.

After he combined the manuscripts of the soldiers and thoroughly summarized his harvest, he began to wander around the city of Taiyuan.

Poor people don't have much treatment, but they are also the ones who test their medical skills.

The existence of medical skills should not be grandstanding or exclusive to the powerful, but should be enjoyed by anyone in the whole world.

Write books and speak, and it will be remembered for centuries.

Hu Yuan suddenly had a target that he was extremely surprised by.

The seeds sown in Taiyuan City are taking root and sprouting, and in Bianjing City, the seeds sown by Zhao Huan are also taking root and sprouting.

The two books that Zhao Huan handed over to Liu Yi brought Liu Yi a lot of thoughts.

So much so that Liu Yi was a little crazy.

"There must be some mystery in these tables that I haven't fully understood." Liu Yi stared at the rice paper in front of him and muttered to himself.

Since Li Gang was promoted to Shangshu Zuocheng, power has spread in Bianjing City.

First of all, the sanitation of the urban area of Bianjing City was greatly improved, and the last time Wanyan Zongwang threw plague clothes in Bianjing City, which made him feel a little palpitating until now.

It was winter, and those clothes flowed into Bianjing City, and there was no large-scale plague.

Otherwise, the consequences will be unimaginable.

For this reason, several fences passing through the water gate in Bianjing have also been renovated.

The dirt roads in the city have been replaced with Sanhe soil and re-tamped, paved with freshly polished stone bricks, and the underground waterways that have not been dredged for a long time have also been re-sorted by Li Gang.

Moreover, a lot of water gates and fences have been added, and if there is such a move as throwing plague clothes again, Bianjing City is no longer resigned to fate.

A big reason for him to do this is that the fortifications of the Yellow River embankment of the Gong Relief Supervisor are almost complete.

A large number of workers and workers are slowly returning to Bianjing.

It's just that Li Gang smelled a different smell, and these migrant workers turned a corner in the Daimyo's Mansion and headed towards Xingzhou.

Liu Yi has recently become obsessed with many inductive ideas learned from "Geometric Originals", and has also felt the different style of numerical calculation from "Tongwen Arithmetic Fingers", which has perfected the arithmetic of the Great Song Dynasty.

Thinking of this, Li Gang had an extremely headache.

The Great Song Dynasty arithmetic, 12 books, 14 years, the questions in the examination are strange and unbelievable every time.

Liu Yi studied arithmetic, and if he went further, the students were afraid that they would go crazy.

However, Li Gang couldn't stop Liu Yi from studying arithmetic, and even needed to help Liu Yi.

Now all the charts in front of Liu Yi are from Qin Tianjian's calendar records, which makes people's scalp tingle.

"This geometry is actually just a summary. Each of these parts can be found in the "Nine Chapters", "Ancient Seizure", "Fixation", and "Island", which is just a summary of this book. Liu Yi muttered to himself.

But the mathematical ideas that are summarized by it, as well as the propositions and proofs, can be used as a reference. The calculation of the same text is not more simple, but it is indeed convenient to write. ”

In front of him was a huge bow diagram with countless triangles densely drawn.

Li Gang couldn't understand the meaning of this bow chart, and he asked himself if he knew more about arithmetic than most students.

But in the face of Liu Yi's research, he had no way to interfere.

"One foot of air, half of it in a day, everything is inexhaustible. Wireless cutting seeks the power of the bow figure, which is the same and has no new ideas. I wonder what the hell I'm trying to know! ”

Liu Yi suddenly shouted loudly, and casually put the paper of the bow chart aside.

Li Gang grabbed this piece of rice paper with his hand, and Liu Yi found it boring, and getting it to the ordnance supervisor was a good recipe for improving ordnance!

This is also the reason why Li Gang moved all kinds of ancient books of Si Tianjian to Liu Yi's room.

Since Liu Yi took the two books from the official family, he has become the appearance of this madman.

"There must be some kind of connection between these objects, but what kind of connection exists? That's what I'm looking for, but what am I looking for?"

"Lesson Method, Today's Technique, Synthesis Technique, Fraction Technique, Equation Technique, Two Deficiencies Technique, etc., Equation Technique! That's right, that's it! ”

"The moon is missing at the beginning of the month, the moon is full in the middle of the month, the moon is missing at the end of the month, and the moon is full again in the middle of the month. As time passed, the moon waxed and waned. The month is one dollar, and the hour is another. ”

"In winter, the days are short and the nights are long, and the days are far and far from the south. In summer, the days are long and the nights are short. The sun is nearing and the sky is in the middle of the sky! The day is one dollar, and the hour is another. ”

"Square, round with its circumference, power, and product, can be one yuan, and the side is another yuan!"

"The total amount of rice, grain, and wheat can be one yuan, and the yield per mu is certain, and the number of mu is another yuan!"

"Everything in the world follows the way, for the sake of the beginning of the week. The Tao can be the way, the very way, the non-constant way, the constant way, the name can be named, the extraordinary name, the non-constant name, and the constant name. Its path is erratic, and its name is uncertain. ”

"Nope! Everything has a way, and its way can also be named! ”

"Where there is heaven in the way, it is the letter of heaven. In this change, if there is a letter to the other, then this is the letter of the other. ”

"I see! Hahaha, I see! Sure enough, a certain is a natural talent! Hahaha! ”

Liu Yi quickly wrote on the paper, and the two books "Geometric Original" and "Tongwen Arithmetic Fingers" brought him enough inspiration, and the solid arithmetic gave him the soil to break through himself, and finally made this mathematics take a step forward.

And Liu Yi wrote a few big characters on rice paper, strain, self-change, endless.

"Li Dazai, is there something wrong with this?" Liu Yi finished his own business, only to see Li Gang standing behind him, for Liu Yi's muttering, Li Gang said, you are too difficult, the student will scold you to death!

Li Gang nodded and said, "I have a question here, which is a question in this year's special official examination for arithmetic. I don't know Liu, can you do me a favor and take a look? ”

Liu Yi has been a little crazy these days, he gets angry at every turn, and when he can't figure it out, he will be reprimanded when he sees anyone.

However, seeing that Liu Yi seems to have some new understanding, he should be in a good mood today.

"There are three drawers today, the first of which contains two books of poetry, the second of which contains a book of poetry and a copy of the Analects, and the third of which contains two books of the Analects."

"Now choose a random drawer, take out a book in one of the drawers, and discover the first book of the Book of Poetry. So, another book in the drawer, which is also the rate of the Book of Songs, is geometry? ”

Rate ancient, Liu Yi naturally knows that it is a word for divination and intercalation, which means how likely it is to appear. It is often used when you are hesitant and when you need to make a decision.

In the past, it was divination, and it continued to develop over the years, and in the Tang Dynasty, the art of resolving doubts has become an important means of resolving doubts in the court.

Liu Yi smiled: "What's so difficult about this, isn't it one-half?" ”

"Huh? Let's take a second look. It doesn't seem right. ”
