Quick Travel: The Story of Your Highness's Pampering of Her Husband

Chapter 110 The replaced noble lady (35)

In order to mobilize the prince's enthusiasm for learning from the beginning, Xuanyuan Xi and Xiao Yi first taught Nangong Rui how to make ice.

Nangong Rui watched as ice cubes slowly formed in the basin where saltpeter was added, exuding bursts of cold air. Although his expression barely remained calm, he was very excited inside.

If this ice-making method is used properly, it is estimated that in just one summer, you can make a lot of money. After all, there are too many people in the capital who are short of ice but not short of money.

However, these two people taught him how to make ice so easily. Did they really not care about money, or did they have a big agenda?

Xuanyuan Xi didn't care whether the other party was more suspicious. She and Xiao Yi discussed the teaching content and then began to act like a prince and a tutor.

The first thing given to the prince was the simplified version of 12345 and the Arabic numeral version of [-].

Originally, Nangong Rui thought it seemed quite simple and convenient, so he studied it without any fuss. With his intelligence, he had memorized it all in just half a day.

After lunch, Xiao Yi took out the lecture notes prepared by Xuanyuan Xi and began to explain how to use Arabic numerals to calculate addition, subtraction, multiplication and division, including the four basic rules of arithmetic, such as the commutative law, associative law or distributive law, as well as factors, quotients Definitions of nouns like this, as well as the most commonly used multiplication tables.

In one afternoon, Xiao Yi gave Nangong Rui all the mathematics content for the third grade of elementary school and below.

Then, His Majesty the Crown Prince was sent away by them without even having dinner.

In my hand, I had a handout written by Xuanyuan Xi, a hundred arithmetic questions given by Xiao Yi from easy to difficult, and a bonus sentence from the two of them saying when they had finished all the questions, when would they come again.

The accompanying palace maids and eunuchs did not dare to raise their heads, and there was silence. Nangong Rui's face was very ugly, but in the end, his interest in this calculation method that could easily produce results without an abacus outweighed the anger of being ignored.

He flicked his sleeves, got into the carriage, and headed home.

Although Nangong Rui is talented and intelligent, he is not able to master what he hears immediately, especially when he was crammed with so much new knowledge in just one day.

Fortunately, I still have the handouts, so you can check them if you forget or have any questions.

Needless to say, addition and subtraction were not mentioned. After understanding the rules, Nangong Rui felt no pressure no matter how many digits he calculated.

But this multiplication and division relied too much on the so-called multiplication table, so he had no choice but to keep reciting it to become familiar with it.

The maid who was standing in the study listened to what His Highness had been saying since he came back from home. She silently guessed in her heart: Could it be that Ji Juren gave His Highness some witchcraft?

It was another two days before Nangong Rui completed the homework assigned by Xiao Yi, took the test paper filled with answers, and rode a carriage to Ji's Mansion in a majestic manner.

Xiao Yi took the test paper, glanced at it, and nodded to indicate that everything was correct.

Just when Nangong Rui felt happy in his heart, Xuanyuan Xi was drinking tea leisurely at the side and said calmly: "It took His Highness the Crown Prince three days to learn just such a few things. A commoner woman and husband mastered it in one day."

"Ah!"

One word immediately made Nangong Rui furious.

No matter how calm and self-possessed he is, Nangong Rui is only 19 years old this year, and he has been praised all the time when he grew up, not to mention that these words came from the mouth of the first woman he had a crush on.

After staying up for several nights in a row, Nangong Rui, who was sleep deprived, suddenly broke through the folding fan in his hand and almost broke it. He choked out "Oh? Really?"

"It seems that Ji Ju and Mrs. Ling's talents are far better than Gu's!"

Xuanyuan Xi continued to criticize others, "Don't be sad, Your Highness, your talent is innate."

"you!"

Before Nangong Ruizhen got mad, Xiao Yi started today's teaching.

The definitions of decimals, fractions, speed, distance, etc., as well as mathematical content for grades [-] to [-] such as solving equations with unknowns and linear equations in two variables.

After finishing speaking, Xiao Yi took out a few more test papers and sent Nangong Rui out the door before lunch.

Nangong Rui is now outside the gate:...

No, don't you think too little of Gu, the crown prince?

Is your attitude so arrogant?

Luck, Nangong Rui comforted himself. People with great talents tend to be aloof. What he values ​​is the knowledge he can learn. It doesn't matter if he feels a little wronged.

After waiting in the study room, Nangong Rui opened the test paper and saw that it was filled with the most troublesome application questions for modern primary school students.

What about a chicken and a rabbit in the same cage, water in the swimming pool, will Xiaoming be late if he forgets to bring his keys to school, and the two cars, entangled, chasing each other, driving in opposite directions, etc. Wait, another hundred questions have been collected.

Of course, those problems were modernized by Xuanyuan Xi. The problem of filling and discharging water in the swimming pool was changed to collecting and discharging grain in the granary. The problem of car driving was changed to the pursuit of two armies. It was all changed to situations related to people's livelihood and the military.

As soon as Nangong Rui saw these questions, the expression on his face became much more serious.He began to study and answer seriously.

Although he could solve these problems according to the methods he had learned before, after studying the four operations in the first two days, Nangong Rui understood that what Xuanyuan Xi and the two gave him were simpler and more systematic mathematical methods.

Therefore, even if he was dissatisfied, Nangong Rui was still willing to study hard.

A few days later, Nangong Rui returned from Ji's Mansion without even using lunch.

Only this time there was no test paper, only a few handouts with knowledge of statistical charts and tables such as fan charts, bar charts, and line charts, and a ledger kindly lent by Xiao Yi.

Nangong Rui pulled out a separate piece of white paper, which recorded the harvest of one hundred acres of hybrid rice and more than ten acres of ordinary rice. He made a table and used various graphics to represent it. The contrast was very obvious, and the advantages and disadvantages could be seen at a glance. visible.

The words Xuanyuan Xi said appeared in Nangong Rui's mind.

From Nangong Rui's questions and answers, Xuanyuan Xi realized that the other party seemed to be studying alone and had not communicated with anyone, so he warned him.

"Your Highness does not need to hide all the knowledge that the common people's wives and husbands have taught you, you can just spread it."

"Although I gave His Highness the example of the rice harvest, how far the graphic chart can be used depends on His Highness' ability."

Nangong Rui also thought wrong for a moment. He just remembered that the two of them told him not to tell the fourth person about that ridiculous thing, but he ignored that there was no need to keep this knowledge.

Tapping the white paper with his fingertips, Nangong Rui understood the meaning of Xuanyuan Xi's words. They were only responsible for teaching, and how to apply it was all up to him.

Those charts and graphs, as well as novel accounting methods, can be applied to various types of taxation of the court, population statistics, and even the loss of weapons and food in the army, etc. All increases and decreases will be clear at a glance.

If there are abnormal data changes, the problem can be discovered immediately.

Instead of continuing to work behind closed doors, Nangong Rui first organized all the things he had learned during this period and sent people back to the capital for his father to deal with it.

As for himself, he called all the diners and staff into the study room and acted as a teacher for a while.

After learning new knowledge for more than half a month, Nangong Rui has become more convinced about the "witch stealing the country".

On this day, Nangong Rui corrected his mentality, prepared the six rituals, and respected Xuanyuan Xi and Xiao Yi as his teachers. Xuanyuan Xi and Xiao Yi naturally agreed.

After the identity of master and apprentice was confirmed, Xuanyuan Xi forced Nangong Rui to practice martial arts on the grounds that "state affairs are complicated and a king needs to work day and night."

As the prince, Nangong Rui naturally had some training in boxing, kicking, and archery, but because he was protected by many top secret guards, he spent more of his energy on learning how to be a king and handling political affairs, and his martial arts committee was not really that high.

Xuanyuan Xi saw the other party's reluctance, but she pretended not to see it. She just said, "What if you are assassinated when there is no one around you?" and she couldn't help but start teaching "martial arts".

Not only did he use his hands and feet, he even used whips and sticks. Xuanyuan Xi was very happy to "teach" him.

That day, Nangong Rui couldn't see anything on his face, but he actually returned with redness, swelling and bruises all over his body.

That night, Nangong Rui planned to find another person to study at Ji's Mansion to avoid suffering that kind of "humiliation".

But Xuanyuan Xi said righteously that they would only teach the prince and not anyone else.

Nangong Rui could not give up on the new knowledge of mathematics, physics and chemistry, so he had to silently recite respect for teachers and continue to study at home.

From then on, Xiao Yi was in charge of "literary" and Xuanyuan Xi was in charge of "martial arts". Nangong Rui's tragic study career began.
