Li Shimin

Li Xuan, on the other hand, walked aside, took out two white porcelain teacups, squeezed a pinch of tea leaves into each cup, and poured boiling water on them.

Immediately, a scent of fragrance came to the nostrils.

"Little Master, what is this?"

Taking a deep breath, Pei Ji asked curiously.

"Tea!"

"Tea?"

Pei Ji was startled, his face full of suspicion.Such a simple flush with boiling water without any sense of ceremony, can it also be called tea?

"Little master, don't you need to boil or fry for a while when drinking tea?"

To make tea is to put raw tea leaves in a pot and boil them, and when making tea, various foods are added to adjust the taste of tea.

Sencha is like frying fish or medicine. It is fried in a cauldron, and some salt or other condiments are added to it. Anyway, the literati of this era have full craftsmanship when drinking tea.

Especially for a literati like Pei Ji who came from a famous family and was an official to Zuo Pushe, drinking tea is even more particular.

In his eyes, the tea Li Xuan brewed was extremely vulgar.

As for Pei Ji's inner activities, Li Xuan didn't know, because he had never seen a scene of literati drinking tea in this world.

However, from the expressions on the faces of Pei Ji and Lawyer Pei, he could tell that the tea he brewed with his own hands was despised by the Pei family and his son!

"Pei Gong can taste it first."

Li Xuan said directly.

If you still dare to dislike it after drinking it, I will replace it with plain water!

"In this case, the old man will taste it first!"

If Li Xuan dared to drink this kind of tea for Pei Ji when he first arrived, Pei Ji might be furious and even walk away.

However, after witnessing Li Xuan's prowess in arithmetic in the dining room, even though Li Xuan is just an unknown person now, the way of arithmetic is worthy of Pei Ji's attention.

After a while, the old man will teach you how to drink tea!

Thinking to himself, Pei Ji picked up the teacup and took a sip.

"Ok?"

Take a sip of hot tea.

Pei Ji's eyes lit up, and then he couldn't believe that the tea brewed with a pot of hot water and a handful of tea leaves tasted better than the tea they had spent half an hour adding so many condiments in the past. !

Slightly bitter, with a hint of fragrance.

I couldn't help but smacked my mouth twice, and took another big gulp.

Still the same, the taste is a little bit bitter, but followed by a strong tea aroma.

“Good tea!”

Pei Ji couldn't help but praise loudly.

The trace of dissatisfaction in his eyes has long since disappeared without a trace.

"This tea will be so fragrant? It's the best tea I've ever had!"

At the side, seeing Pei Ji's praise, Attorney Pei couldn't help picking up his teacup, took a sip, and quickly praised him.

"Before drinking tea, stir-fry the raw tea leaves and soak them in boiling water, that's it!"

Li Xuan was a little inexplicable.

Forehead!

Hearing this, Lawyer Pei was stunned, it was so simple.

Thinking of the many tedious processes they had to drink tea before, they couldn't help being a little bit shocked, so they sat there quietly and began to taste tea.

On the side, Pei Ji was also taken aback, and then smiled wryly.

I don't want to talk too much!

"Pei Gong, did you figure out the little master's math problem?"

At this moment, Li Shimin, who was awakened by the voices of several people, had already walked to the side of several people at some time.

"My lord, I am ashamed!"

Hearing this, Pei Ji quickly stood up, his face even more depressed.

"Even Pei Gong couldn't solve it?"

A trace of disbelief appeared on Li Shimin's face.

"Little Master's attainments in arithmetic are far beyond the reach of this old man, and I am ashamed!"

Pei Ji had a wry smile on his face, his heart was filled with despair.

Thinking of him, Pei Ji, who was born in the Pei family in Hedong, he has been familiar with hundreds of books since he was a child, and he is even more proficient in arithmetic. At the age of 14, he was appointed as the governor of Bingzhou, and then he was promoted all the way.

When the Li family was about to raise an army, Pei Ji contributed a lot, and then his official career went smoothly, until now Zuo Pushe.

Unexpectedly, now he can't even figure out the arithmetic problem that a young teacher from a mountain village casually asked.

"I don't know if my little master can clear up my confusion for me. What are the prices of the final pears and fruits?"

Seeing that Pei Ji thought he was inferior, Li Shimin felt secretly refreshed.

Afterwards, curious about the final result, he still asked Li Xuan.

"Wait a moment, everyone!"

Seeing these people coming to seek abuse again, Li Xuan chuckled lightly and stood up.

From the wooden cabinet on one side, he took out a piece of paper and placed it on the coffee table.

"This question is very simple. If you do the math, you can understand it right away with the intelligence of Peigong and the king!"

"Assuming that the pear is x and the fruit is y, then it can be calculated like this!"

"The price of each pear is 11/9 cents, and the price of each fruit is 4/7 cents!"

“如此，可列方程式：11/9x 4/7y=999x y=1000”

"...It can be calculated that there are 657 pear x and 343 apple y."

"Then, the total price of pears is 11/9x657=803 Wen."

"The total price of fruit is 4/7x343=197 texts."

"How is it? My lord, does Mr. Pei understand it? Isn't this question very simple?"

Li Xuan asked.

……

Chapter 20 is called Numbers!

"..."

Unexpectedly, when she turned her head, she saw Li Er and Pei Ji, all of whom were stunned, staring blankly at the piece of paper on the table, motionless.

"Pei Gong? Your Majesty? Pei Ming Mansion?"

After a while, Li Xuan couldn't help but let out a soft cry again.

"what?"

Now, Li Er and Pei Ji came back to their senses.

At the same time, the look on Li Xuan's face was even more inexplicable and weird!

"Your Majesty, Mr. Pei, what's wrong?"

"Little master, can you calculate the final result just by writing a few times like this?"

Pei Ji couldn't believe it.

I held a counting chip on the table, racked my brains, and calculated the calculation problem that I hadn't figured out for nearly an hour. Li Xuan just wrote less than a hundred words, and calculated it easily?

"Pei Gong can do the calculations himself!"

Li Xuan smiled softly, "Such a simple calculation problem, in another year, those children in Lijiazhuang Village can also calculate it!"

Hearing this, Pei Ji was hit hard again.

Although he had faintly agreed with Li Xuan's algorithm in his heart, he still had a little extravagant hope.

Li Xuan has already calculated the final result, and it will be very simple to check it again with the calculation chip.

Therefore, within a short while, Pei Ji put down the counting chip in his hand with a look of loneliness.

He bowed his hands to Li Shimin who was watching the play, and said, "Your Majesty, my master's calculations are not bad at all!"

Then, he looked at Li Xuan with ecstasy.

"May I ask you, what kind of characters are these characters that have such miraculous functions that they can solve such difficult problems so quickly?"

At the same time, Li Shimin and Lawyer Pei also stared at Li Xuan closely.

"Pei Gong, this kind of characters are numbers, this is one, this is two, this is three..."

"This kind of characters is the most suitable number for arithmetic. The combination of the two can represent a larger number. For example, the combination of one and two is twelve, the combination of four and five is 45, one, three, six Combined, it is 130 six..."

"Such a combination, coupled with Jiujiu song, the calculation of addition, subtraction, multiplication and division is the simplest!"

After speaking, Li Xuan picked up the teacup, took a sip of tea, and moistened his throat.

The three of Pei Ji and Li Shimin were dumbfounded.

The three of them are all people who have passed the arithmetic. Although they still don't understand Li Xuan's explanation, they already have a general understanding in their hearts.

They never thought that there are such simple and easy-to-use numbers in the world.

If such a number is applied to government affairs, how convenient will it be?

Thinking about it, Pei Ji and Li Shimin couldn't help but look at each other.

Immediately, he turned his head and stared at Li Xuan closely.

"Little master, this kind of number is so miraculous, which great sage created it?"

"No, it was created by the kid!" Li Xuan replied calmly.

"Created by the little master?" Pei Ji looked surprised.

"Exactly!"

Li Xuan nodded again.

Although it is a bit embarrassing, in this era, he is the first to come up with numbers.

"Little master is indeed a great talent. If this figure is used in the account book, the officials in the world can save at least half of the effort!" Pei Ji said with a happy face.

"Not only that, you can use this number for everything that needs to be calculated, such as leading troops to fight, transporting supplies, building bridges and building roads..."

Li Xuan added.

"Wonderful?"

Hearing this, Pei Ji was taken aback.

At the same time, Li Shimin and Lawyer Pei also reacted.

It seems that as the little master said, there is nothing that does not need to be calculated.

"The old man is an official in the world, thank you little master for creating numbers!"

Pei Ji quickly said: "This great achievement, I will definitely report the truth to the sage, and ask the sage to bestow the grace of heaven and reward the young master!"

"This king will also report to the saint like this!"

"Thank you, Your Majesty and Mr. Pei!"

Li Xuan was unmoved in the slightest, with a calm expression on his face.

"If the sage really wants to reward the boy, please ask the king and Pei Gong to give the sage a suggestion to reward the boy with more iron and grain. If there is white flour, it would be great!"

Forehead!
