Datang: Acting as a celestial mystery at the beginning

When Li Yi'an said this, he agreed!

Li Shimin suddenly excitedly said: "Of course there is no problem, then sir, we have decided like this?"

Isn't it just arranging Wei Zheng's position? For him, the lord of the Tang Dynasty, it's not a problem at all. As long as the impact is not too big, he can solve it with one sentence.

Li Yian nodded, he agreed.

"By the way, there are perfumes and books that Mr. gave us, as well as those arrangements. Do you want to continue?" Li Shimin remembered that letter.

"Of course continue. Here I will teach Mr. Lang a new word and spread the word."

Li Yi'an smiled and said, "Let me ask, if the wives of other court ministers know about the things that are used by the empress, will they also use them? After they find it useful, will they help us spread the word? This is also a simple little idea. means."

"Mister's strategy is far inferior to mine!"

Li Shimin sighed for a while, and continued: "I have to go back immediately, first prepare to establish Chang'an Bookstore, then announce the government-run business, dismiss the current Chang'an Salt and Iron Envoy, there will be a result within three days, please rest assured, sir."

Before he left, Li Yi'an asked him to take some perfume and books back to his eldest grandson Wugou.

In this era, agriculture is emphasized and business is suppressed, and agriculture is the foundation.

After hearing Li Yi'an's words, he immediately decided to run a government-run business. Li Shimin is also a courageous person.

Afterwards, Li Yi'an also left the factory, and when he returned to the yard, he saw Wanshun and Li Lizhi having fun beside him, while Li Chengqian, Chang'an Sihai and the others stood idly by.

"Come here, let's continue to teach you today."

Li Yi'an called them into the living room, and continued: "This time I have an arithmetic class with you, but my class is different from yours."

Arithmetic has existed since ancient times. The famous "Nine Chapters on Arithmetic" was written around the first century AD, and various mathematical problems are recorded in it.

Arithmetic, also called arithmetic, is one of the six arts of a gentleman.

After all, Li Yian brought up his special chalk, wrote down the numbers from 0 to 9 on a blackboard, and continued: "This is called a number!"

Arabic numerals have been invented in this era, but they have not been widely spread. The newly invented numbers are not exactly the same as the numbers of later generations. Mathematicians have evolved into the most commonly used numbers in later generations after continuous discussion. character.

Next, Li Yi'an explained the problem of numbers to them, and then took out the geometric area calculation formula in Chapter 1 of "Nine Chapters of Arithmetic", and also extended the problems of congruent triangles and similar triangles in later generations.

He taught them everything he knew.

Cheng Chumo and the others fell asleep when they heard all kinds of formulas. At first glance, they were the scumbags among the scumbags. It also reminded Li Yian of the fear of being dominated by mathematics.

Only Li Chengqian was a little different. This guy seemed to be very interested in these mathematical problems, and he listened with gusto.

"This prince is a bit interesting."

Li Yi'an thought to himself.

Unknowingly, the time came in the afternoon of the same day, the class ended, Li Yi'an sent them away, and returned to his study.

There is a long blank picture scroll placed here. Li Yi'an picked up the brush, thought for a moment, and started to paint.

His painting skills did not come from the system. He was an art major in later generations and was good at all kinds of paintings.

The painting style of the Tang Dynasty, before Wang Wei created his own school, was mostly realistic. Before painting, he would use the base ink to outline, and then set the color and paint. After going through several processes, a painting is considered complete.

Li Yi'an's style is completely different from the current one, using the style of Wang Wei's combination of poetry and painting, and adding some special techniques from later generations. After a long time, the brightly colored pictures appear on the paper.

What first appeared on the screen was the sparkling water of the West Lake, and the Leifeng Pagoda looming in the distance. Under the Leifeng Pagoda, there was a broken bridge. As the screen stretched from far to near, a pavilion appeared on the shore of the West Lake. side.

Under the pavilion, there are lotus flowers blooming in the lake, and the lotus leaves are green. Among the green, a snow-white tail touches the lake water, splashing a splash of water. There is also a blue tail, intertwined with the white tail, as if blending into the emerald green in the lotus leaf.

The owners of the two tails are two pretty women, one in white and the other in green, cuddling each other.

Next to them, there is an incense burner, and the smoke rises faintly.

"Perfect!"

Li Yi'an looked at his own painting, whether it was the artistic conception, the composition of the picture, or even the color of the whole painting, it was perfect without any blemishes.

Suddenly, he felt that something was missing. After thinking for a while, he picked up a pen and wrote two lines in the blank space in the upper right corner.

Half mortal heart and half immortal, Crescent Sky pays for 1000 years.

It is difficult to break the world with a broken bridge, and continue the frontier by the West Lake.

"Wow!"

At this moment, Li Yi'an suddenly heard an exclamation from behind.

Looking back, Wanshun didn't know when she opened the door and came in, and said in surprise, "Brother, this painting is so beautiful!"

The little girl was infatuated when she saw this, her big eyes sparkled.

"Does it look good?"

Li Yian laughed.

"Beautiful, brother, did you draw Xiaobai and Xiaoqing?"

Under the influence of her sister, Wanshun also knows the specific content of the story in "Legend of the White Snake", and can recognize it at a glance.

"It's them."

Li Yian laughed.

"Sister, sister, come quickly!"

Wanshun bounced out of the door, shouting as she walked, "Xiaobai...Xiaoqing..."

This girl, Li Yi'an smiled and reminded: "Go slowly!"

After a while, she dragged Li Changge into the study.

When seeing the painting for the first time, Li Changge's eyes froze, and then her eyes widened. She is definitely the most loyal fan of Xiaobai and Xiaoqing.

"Xiaobai and Xiaoqing are so pretty, sir, can you give me the painting?"

Li Changge took his hand and asked expectantly.

"No problem at all."

Li Yi'an originally wanted to use it for publicity, but seeing that she likes it so much, I will draw another one later.

"Thank you sir!"

Li Changge blushed pretty, hugged Li Yi'an, and happily put away the frame.

After realizing it, her pretty face turned even redder, and she looked at Li Yi'an with a pretty face.

"A painting can make you so happy."

Li Yian laughed.

"The paintings are not only Xiaoqing and Xiaobai, but also painted by Mr. Lang himself."

Li Changge blushed and said, "I will definitely keep it well until forever, and I will never throw it away."

"Just like what Sister Yan'er said, is Sister Auntie going to marry Brother Aunt soon?"

The little girl was ignorant, her big eyes were full of anticipation.

"Wan Shun!"

Li Changge said shyly.

"It depends on whether your elder sister is willing or not. After this busy period, I will take Wanshun and Changge together to see Ah Weng, okay?"

Li Yian asked.

Going to see Li Yuan is equivalent to proposing marriage.

Thinking of this, Li Changge felt rippling in his heart.

"Good good!"

Wanshun happily raised her small hand and said, "I haven't seen Ah Weng for a long time, I miss Ah Weng."
