All of Li Yuanjia's collection of books on the surface, including those he "wrote" himself, did not intend to hide from Fang Fengzhu. Even Li Yuanjia hopes that Fang Fengzhu likes to read, and if he has time, it is best to read all these books.

After all, they are going to live together for a lifetime, and Li Yuanjia doesn't want to guard against it every day.

Besides, there's no need for that.

And when he thought that he must be the "originator" of countless disciplines in his life, Li Yuanjia felt that Fang Fengzhu had to be transformed, otherwise, if Princess Han, who was born in Fang Xuanling's house, saw that he was addicted to "strange lewd skills" all day long, what should he do if he persuaded him every day?

It's annoying.

So when he entered the study, he took Fang Fengzhu to look at his collection of books, and after a burst of amazement, Li Yuanjia directly took out the "copies" of those math books: "Fengzhu, if you have time in the future, you can read more of these books." ”

"Mathematics? Book 1? ”

Seeing the name on the book cover, Fang Fengzhu's eyes suddenly lit up: "This is the one you wrote, the king...... The book of Tianzhu Numbers? ”

Hearing Fang Fengzhu say this, Li Yuanjia was immediately happy: "Fengzhu also knows the Tianzhu number? ”

"I've just heard of it."

Nodding a little shyly, Fang Fengzhu pursed his lips and smiled: "The eldest brother once mentioned it once at home, saying that the Tianzhu number used by the king is simple and easy to use...... Bong-joo has always been curious, but he only saw ten numbers from his eldest brother. ”

"Haha, this time you'll be able to see the whole picture."

Shrugging his shoulders, Li Yuanjia said with a smile.

He had used Arabic numerals once or twice in front of Fang Yizhi, which was regarded as a preventive shot in advance, but the brother-in-law was obviously not very interested. However, the little beauty in front of him, of course, Li Yuanjia can't let it go easily.

So after a slight pause, Li Yuanjia continued: "Fengzhu, now all the stewards in the palace keep accounts and report accounts, using these Tianzhu numbers, you, as the mistress of the palace, will inevitably be in charge of the inner government in the future, these books are unbearable, and the Tianzhu numbers and simple use have to be learned." ”

"Huh? Are they all Tianzhu numbers? ”

After listening to Li Yuanjia's words, Fang Fengzhu's eyes widened in surprise.

She is not surprised at all about being in charge of the inner mansion of King Han, after all, as a princess, this is the power she deserves. And as the eldest daughter of the Liang Guogong Mansion, Fang Fengzhu has been educated in this area since she was a child, so she naturally knows it. However, all the stewards of the Han Wangfu used Tianzhu numbers to keep accounts and report accounts, which was beyond the scope of Fang Fengzhu's ability.

"Yes, it's all Tianzhu numbers!"

Tilting his head and glancing at his little wife, the smile on the corner of Sun Peng's mouth was very obvious at this time - he forced those people to learn to use Tianzhu numbers, even Han Shan, who was in his forties, was no exception, but it was not just to make himself more familiar and comfortable to read those reports.

Fang Fengzhu, who is surprised now, isn't that one of the results?

So when he took out a book and put it in front of Fang Fengzhu's eyes, Li Yuanjia's eyes began to flash brightly: "This is the first volume of "Tianzhu Numbers", after you read this one, you will read the second book "Addition, Subtraction, Multiplication and Division", and you will soon understand what is going on......

After flipping through the first page of "Tianzhu Numbers", Fang Fengzhu sat down in Li Yuanjia's study.

This sitting is an hour.

Although for Li Yuanjia, the so-called "Tianzhu Numbers" book is as simple as a stick of incense to read it, after all, the content is to explain the origin of Tianzhu numbers, the concept of zero, and the decimal algorithm, etc., but for a little girl in the sixth century AD, it is not easy to understand it thoroughly.

Even with a good teacher explaining by his side, it took Fang Fengzhu an hour to completely figure out what is called an integer, what is a decimal, what is a positive number, and what is a negative number......

It's a little boring, but Fang Fengzhu learns very carefully.

Because she knew that the kneeling of Han Shan and the others only made her the nominal hostess of the Han Palace, but if she wanted to become the real hostess, she had to control everything in this palace!

She is a princess, and this is her duty.

The education he received since childhood made Fang Fengzhu almost abandon all distractions, and he has been seriously studying the book "Tianzhu Numbers". And after finishing learning, I didn't feel that it was enough, and even picked up the second book "Addition, Subtraction, Multiplication and Division" directly - although I can't compare with those great Confucians in terms of knowledge, but I am also from a scholarly family, and Fang Fengzhu has also learned logarithm since he was a child, so he learns much faster than Han Shan and Li Zhong.

But no sooner had she turned the page of the second book than a large hand grabbed her little hand and closed it again.

"Alright, that's enough for today."

Just when Fang Fengzhu's face turned red and he wanted to say something, Li Yuanjia had already stretched his waist and said with a smile: "Speaking of which, today is the first day after we got married, except for going to the palace, is it possible that you plan to spend it in this study next?" ”

"Uh......"

"Haha, hurry up!"

Pulling Fang Fengzhu's little hand, Li Yuanjia laughed and said, "Look at the sky outside, but it's not early." Let's go, I specially instructed Yu Niang to prepare a table of good dishes tonight, and if Fengzhu is interested, she can accompany Benwang for a drink......"

……

Sitting in a special restaurant, Fang Fengzhu always feels that everything is fresh.

She didn't have much of the heart to pay attention to these things during breakfast and lunch, especially at noon, when she thought of going to the palace to meet the emperor, Fang Fengzhu's mind was always unstable. But now that night came, she immediately noticed something different in the room.

The room is not large, with only one square table.

Fang Fengzhu knew that this room called "restaurant" was specially used for eating, and it was only for her and the king, but it was still a little too small. And there is only one table in the house, which is very different from Fang Fengzhu's usual habits - he must be at the same table as Li Yuanjia when eating, and he is very close.

Around the square table is a row of very strange cabinets.

Below are open cabinets, but starting from the waist of the person, the top is a grid, square or round, and some oblique squares. And in some of the lattices, there are also some objects such as small vases, small wine jars, etc., which are very interesting at a glance.

After looking around, Fang Fengzhu subconsciously bit her lip.

Although she has only lived in Han Wang's Mansion for a day, the new things that the little girl has seen have exceeded the sum of the previous ten years, especially the one she and Li Yuanjia live in......

Thinking about it, Fang Fengzhu's little face couldn't help but blush again.

glanced at Li Yuanjia weakly, and found that he didn't pay attention to himself at this time, but reached out and took a small wine pot that Chunyan had just brought over: "Fengzhu, do you want to taste the wine we brewed in our house?" If you think it's good, I'll send some ...... to Liang Guogong tomorrow."
