Chang 'an City, Chai family.
In the evening, Li Xiuning sat on the heated brick bed and ate some pastries while leisurely reading her storybook.
In ancient times, there was almost no entertainment in winter, and the gatherings of families were much reduced in cold weather.
"The things have been delivered to the Zhou Estate?"
Chai Zhewei glanced at his younger brother, whose mouth was full of snack dregs, and happily asked his mother for credit.
"Yes, there are almost no vegetables in the north in winter. Only my mother and the emperor uncle have a warm pool under their name, so they can occasionally eat fresh green vegetables.”
"Well, Uncle Zhou Wang is not a stingy person. His son didn't even mention the snacks, but he directly sent a big food box in return.”
"Speaking of which, this trip to uncle Zhou Wang's house really opened my eyes. Uncle disliked kneeling and sitting on the ground, so he specially developed…"
Chai Zhewei began to talk about what he had seen in the Zhou Prince's residence, his words unable to hide his envy.
After her son finished speaking, Li Xiuning thought for a moment and finally poked her son with her index finger.
"Oh! Mother should also pay for tables and chairs at home, okay?”
"Thank you, Mother!"
Chai Zhewei's eyes lit up when he heard this, and he responded loudly.
……
The sky gradually darkened. The guards of Prince Zhou's residence patrolled the residence seriously. The guards still had no intention of relaxing.
Li Yuanfang entered the study after dinner. There were two servants guarding the outside of the study. There were strict orders not to allow maids to enter.
As long as the fireplace was lit in the modified study, the study room would still be warm.
At this moment, Li Yuanfang was only wearing relatively light clothes. He was focused on completing today's homework.
Looking at his almost neat calligraphy, Li Yuanfang secretly heaved a sigh of relief.
It was really difficult to write with a brush, and it was hard to control the strength of the brush.
Fortunately, hard work paid off. Today, he finally touched the door.
After practicing for an hour, Li Yuanfang rubbed his aching wrist and massaged himself seriously.
This set of massage techniques was learned from the old imperial physician to avoid the swelling and pain of the wrist caused by practicing calligraphy.
Of course, apart from practicing his calligraphy, Li Yuanfang had also been trying his best to adapt to the current environment.
Not only did he seriously study the current popular Confucius and Mencius, but he also learned the knowledge of mathematics, physics, and chemistry that the AI could only learn on a tablet.
After completing the standard homework for the day, Li Yuanfang sat quietly for a while and suddenly thought of something.
He really wanted to use up the ancient smalllessness prevention atlas before he came to the residence.
For every feudal dynasty, smalllessness was an incurable disease that could not be prevented.
"We still have to promote the spread of the vaccine. Even if we practice the Footloose Technique and understand martial arts, we still can't resist the invasion of the virus.”
Li Yuanfang sighed. He thought about how the small-scale flower would cause many innocent people to die tragically. Since he had the ability to solve it now, he could not bear to enjoy it alone.
Thinking of this, Li Yuanfang used up the ancient smallflower prevention atlas.
The album did not describe the production of the vaccine, but the development history of the disease.
This included the human acne technique that had become popular in the Song Dynasty. The human acne technique had flaws, the most obvious of which was the high mortality rate.
If they wanted to prevent it from happening, they could only promote cowacne.
Ahem, Li Yuanfang's memorandums only mentioned the following.
First, the water supply project was planned after spring.
Second, build new houses for the tenants in the village in the spring.
Third, expose the dangers of inbreeding.
Fourth, develop the various values of pigs
Fifth, in order to save his life, he should promote the vaccine as soon as possible to completely prevent the attack of the smallola virus.
Among these five points, Li Yuanfang felt that the third point was the most difficult. At this moment, it was the trend to increase the relationship between the two parties.
He himself lacked tolerance. How to collect evidence to prove that it was not suitable for marriage within three generations was really a big problem.
He had never expected Xiao Yu to be the one to deliver the breakthrough.
The reason for this happened when Li Yuanfang first went to the Xiao Manor, oh, it was also when he handed in his homework at the Duke Song Manor.
On this day, Li Yuanfang personally brought his homework to see Xiao Yu.
Xiao Yu, who was already fifty-six years old, was still healthy and energetic. He was still concerned about the political affairs of the Tang Empire.
"Disciple greets teacher."
A clear voice of a young man rang out. Xiao Yu raised his head from the pile of documents and smiled faintly at the youngest disciple.
"Hand in your homework and let me see if your handwriting has improved.”
"Yes, sir!"
Li Yuanfang responded obediently and gently placed the wooden box containing the homework on the desk.
That's right, it was a desk with a chair.
As the old saying goes, a teacher for a day is a father for life.
A set of sculpted patterns and a rocking chair were given to her father, Li Yuan.
A set of sculpted patterns and a recliner were given to his teacher, Xiao Yu.
In terms of etiquette, Li Yuanfang didn't want to be criticized by some people, and at the same time, he also killed a lot of trouble.
No matter what Xiao Yu was doing, his attitude was very serious, even when he was checking his disciples 'homework.
"You've improved a lot. You've put in a lot of effort.”
Xiao Yu nodded in satisfaction. The words were like the person. The little disciple's words were no longer so ugly that they couldn't be seen.
Putting down the paper in his hand, Xiao Yu glanced at the thick account book on the desk and then at Li Yuanfang.
After a long time…
Xiao Yu weighed his options and asked seriously.
"His Majesty said that you like to study things and are not interested in orthodox literature such as the Four Books and Five Classics.”
"Dissatisfied with teacher, this disciple is not attentive, but I have not missed out on what I should learn.”
"Hehe, don't look so sad. I don't intend to test you. I just want to ask you how your ability in arithmetic is.”
"Yes, I'm not boasting, but I'm not afraid to compete with anyone in arithmetic.”
"Cough cough, in that case, help me calculate this stack of account books and see if there is any discrepancy between your calculations and mine.”
"Sure,"
Li Yuanfang nodded his head decisively. He flipped open the account book and took out the palm-sized abacus from his waist. He began to calculate the calculations.
Xiao Yu was already resting, so he wanted to see if Li Yuanfang could pass the test and get some help.
On the contrary, Li Yuanfang didn't say a word. He took out an unfamiliar tool from his waist and flipped through the account book quickly. For a moment, his interest was aroused.
However, Li Yuanfang didn't know how to read minds. He didn't know what Xiao Yu was planning. At this moment, he naively complained about the series of numbers written by the man. It was very easy to make people dizzy.
"Sigh, it would be great if I could change this string of Chinese characters to numbers.”
"This account book is a little bad. It's easy for people to take advantage of it…"
All in all, from the moment Li Yuanfang began to move the abacus, the complaints had never stopped.
"Teacher, the first account book is done. Disciple's calculation is the same.”
