After all, Princess Tong'an is old, and she is not a person with force like Princess Pingyang, so her physical strength is not very good. The saint was also old, and after wandering around for a while, he went back to the palace.

Before leaving, Princess Tong'an glanced at Princess Pingyang's stomach and patted her hands. Xue Lang didn't know why at first, but looking at Princess Pingyang's slightly shy expression, he suddenly understood! After I understood, it hurt a little-

It's been spawned again! What an experience it was to be a father at the age of twenty-six! I'm so tired!

The husband and wife glanced at each other comfortingly, quite helpless. After shopping for a while, I went to a clean-looking food stall and ate a bowl of wontons for supper before going home. On the carriage, Princess Pingyang looked thoughtful, and Xue Lang asked, "What's wrong?" ”

Princess Pingyang said: "I just saw the people around the prince scolding a group of Xiaolang. I'm thinking, aren't those people Chang Lin Wei raised by the prince? ”

Speaking of Chang Lin Wei, he frowned slightly, obviously, he looked down on the so-called Chang Lin Wei very much.

"Do you know about Chang Lin Wei too?"

Princess Pingyang nodded and said, "This is not a confidential matter, it is not difficult to know." The dignified prince actually raised evil young ...... It's really ......."

The words were not finished, but the disgust was overflowing. Xue Lang patted her hand and didn't say anything. Neither of them planned to interfere in this matter, so they naturally said that even if Princess Pingyang was very disgusted with the prince's move, she didn't say anything.

Don't mention it, when he returned to the princess's mansion, he was already about to be born, and after washing, he lay down on the bed, Xue Lang hugged the person very righteously and said, "My dear, in order to no longer be born, let's work hard!" ”

Princess Pingyang was a little shy and a little sweet by his dear call, but she didn't have any feelings at this time, and said coquettishly: "You shouldn't let you talk!" ”

Reach out and pull someone's head down, blocking out someone's unspoken laughter. After the curtain, the wheezing sounded—

Long...... Long......

After a long time, the person who was supposed to rest suddenly sat up from the bed, and said something to Princess Pingyang's stomach while making a gesture: "Little tadpole, you must work hard tonight!" Don't disappoint my expectations from the host! Also, I wish I had a daughter! Yami Tofu! ”

The princess was quite tired and was about to sleep, but when he made her feel like this, she was puzzled: "What is Lang Jun doing?" Rest in peace! ”

Xue Lang said: "I'm praying for fertility!" ”

Princess Pingyang was stunned, her face turned red, and she couldn't help but push him: "You ...... person"

"Boom!"

The newlywed colt has fallen into bed! Falling on the bed pushed by a newlywed wife!

Princess Pingyang was stunned for a moment, then laughed, laughed uncontrollably, collapsed on the bed, and said while laughing: "Lang Jun, it is not intentional to be a wife!" ”

Xue Lang got up in a gloomy way, nodded and said, "Yes, you did it on purpose!" ”

After finishing speaking, he paused, and said in the tone of an announcer: "Why is the husband pushed out of bed by the newly married couple?" The reason turned out to be ......"

Before he finished speaking, he was pulled down on the bed, and the quilt was pulled, covering the person on the bed, and there was no sound.

After the Shangyuan Festival, with the resumption of work in various departments of the imperial court, the new year and new atmosphere, the imperial court issued a series of policies and regulations, among them, the first volume of "mathematics" written by Xue Lang was listed as one of the textbooks of the Guozi supervision discipline by the imperial court together with the Ten Classics of Arithmetic, and announced to the world, recommending this book as an enlightenment book of arithmetic.

At the same time, the sage announced to the world that Princess Pingyang of Anguo took pity on the poor scholars for not being easy to study and had no way to study, so she asked the sage to set up a national public library in Chang'an and Luoyang, which will be opened soon!

This library was funded and prepared by the Sage Inner Library, and the printing workshop under the name of Princess Pingyang of Anguo was responsible for printing and supervision. Now in Chang'an, he is seeking to borrow books from various collections for printing, and accepts contributions and book donations from famous artists. Anyone who donates books will have their names and surnames engraved on the exterior walls of the library.

In addition, the saint's edict that the library is only allowed to be established by the state, and no one is allowed to set it up, and if there is a violation, it will be punished for crime! In addition, the introduction of the functions of the library was posted in Chang'an and Luoyang in the form of notices. For a time, the scholars in Chang'an and Luoyang ran and cheered, and some scholars jointly entered a book of ten thousand words to the saints, calling them the saints benevolent and the lords of the saints!

Xue Lang's math book came out, and of course, he was not immediately called a generation. Although there are several poems and books on the six arts of the gentleman, the most sought after is Jinshi now, and the subject is just the last choice. In the past dynasties, none of them can reach a high position, let alone compare with the great Confucians.

However, Xue Lang was invited by Guozijian to give a few lectures to the doctors of arithmetic, mainly to introduce Arabic numerals called simple numbers, and to teach these doctors so that they could teach their students.

These people are all people who have been immersed in arithmetic for a long time, and they can understand it at a glance, and they can see the benefits of using simple number calculations at a glance, and they look at Xue Lang with admiration, and they all say that they are worthy of being people who write books and pass on books, and they can be called masters of arithmetic.

Xue Lang was praised silently and blushed, and it was hard to say that this was copied, so he could only accept it. Of course, his so-called everyone is a parallel import, only circulating in the discipline, and outside, he is still the illiterate who can only use the vernacular and can't write limericks.

Wit...... What's that? Have you asked the opinions of the Confucian scholars in Chang'an City? Therefore, Xue Lang did not have a sense of swelling after becoming famous, and still went to work calmly, did things, and did his work steadfastly.

In such a busyness, there is also a great joy -

Jiang Lin and Su Siniang's first child was born, and he was a big fat boy!

The production process was quite smooth, and the child was born healthy, which was a very happy thing in the Tang Dynasty, an era when the infant mortality rate was extremely high.

On the third day of washing, Xue Lang and Princess Pingyang went. Jiang Lin came to greet him in person, Xue Lang looked up at the small bow hanging on the door, and was quite envious-

Obviously, Jiang Lin has a son, and he doesn't have to be born again in the future! Poor him, he can't get out of the situation he was born into!

And Princess Pingyang obviously has a relationship with him, when she went to see the mother and the child in the back, she hugged the baby for a while, and she couldn't put it down for the red baby.

Ah Lin's eldest son's Xisan didn't make a big deal, but just invited close people to participate. Jiang Lin and his family felt that the child was still young and should not be done in a big way, so as not to lose their fortune.

At the baptismal ceremony, this child, who was temporarily called Da Lang, was finally given a milk name by his father, called Ahri. When he first heard the name, Xue Lang squirted out a mouthful of water-

Ahri, that's the name of a red-haired fox in little white pants!

However, as a local native, Princess Pingyang thought the name was good, and Princess Pingyang said: "Tanuki, bobcat also, agile and cunning, strong and easy to grow." There is a folk saying, and cats have nine lives. May Dalang people grow up healthily as their name suggests! ”

Seeing that everyone thought it was good, Xue Lang shut his mouth tightly and didn't say more. However, I think of the habit of naming children and naming them cheaply, so as to take the metaphor that cheap names are easy to feed. Didn't His Majesty Taizong, who will be wise and martial in the future, give his precious daughter the nickname of his son!

That's a rhinoceros!

A cute, cute daughter is named Rhinoceros! Xue Lang couldn't help but open his mind-

According to this standard, will his children be named Xiong Da and Xiong Er in the future? !

ohno！

Xue Lang was simply intimidated by his own brain hole! Silently determined, if anyone dares to name his child Xiong Da and Xiong Er, he will definitely fight to the death! I completely forgot that the child's shadow has not yet been seen, and it is still a very distant thing to choose a name, so it can be seen that he is actually quite anxious about being promoted!
