After standing behind Fang Fengzhu for a while, Li Yuanjia stretched out his right hand and put it on his princess's little hand, and asked with a smile: "Fengzhu, what do you want?" ”

"Huh?!"

Fang Fengzhu, who was stunned, suddenly found that he had an extra hand in front of him, and was naturally startled, and then he was relieved when he heard Li Yuanjia's familiar voice.

"The King's ......"

"Okay, I've said it, you don't have to be polite when it's just you and me!"

Pressing Fang Fengzhu on his seat, Li Yuanjia frowned a little unhappily and said lightly. If you want to talk about his princess, Li Yuanjia is quite satisfied in most places, although she has not had too deep feelings until now, but at least she looks beautiful, has a good figure, and is knowledgeable and gentle. But there is just one point that Li Yuanjia has a headache, that is, it is too much courtesy.

I don't know if it's because of the old house, this girl is also a one-sided at home, whenever a trace of tenderness rises in Li Yuanjia's heart, she will always be coldened by her sentence "The concubine has seen the king".

So after secretly laughing bitterly, Li Yuanjia didn't want to say more, and sat directly next to her and said with a smile: "Fengzhu, what were you thinking just now?" ”

"Uh......"

After a pause, Fang Fengzhu smiled bitterly: "It's nothing, it's just that my sisters came over as guests today, and they are all very interested in glass, and I also promised them, and I will set aside ten or twenty yuan for them when I go back......"

"Haha, it's a trivial matter, I'll let Han Lucheng write it down later."

"Thank you, Your Majesty."

After listening to his words, Fang Fengzhu was polite first, and then continued in Li Yuanjia's disappointed eyes: "Besides...... Before leaving, Sister Shuyue and Sister Qinglan asked me to take a set of "Mathematics"! ”

His eyes widened suddenly, and Li Yuanjia asked in surprise and joy: "Mathematics? Are you saying that anyone is interested in those six books? Sister Shuyue...... Which lady is she? Which is Qinglan's sister? ”

"Wei Shuyue is the second lady of Zheng Guogong's family, and Qinglan is from the palace of Hejian County."

"Wei Zheng? It's him? ”

Ignoring Fang Fengzhu, whose expression was slightly bitter, Li Yuanjia raised his eyebrows, and couldn't help but be a little surprised.

The daughter of the king of Hejian is his niece according to generation, although the girl Li Yuanjia has never seen it, but with Li Xiaogong's reputation for poverty and luxury, it is not very strange that his daughter likes mathematics that can be used to manage money. However, Wei Zheng's antique daughter is also interested in mathematics, which is a bit surprising to him. Although Li Yuanjia didn't have much contact with the big guy, he also knew that the old man was the most conservative and stubborn, but his daughter would be interested in mathematics?

"Yes, that's him."

After nodding, Fang Fengzhu's eyes dimmed suddenly: "It's just that although Sister Shuyue took away the math book, and the glass is also very popular with them this time...... Lord, I always feel that I am deliberately deceiving them, what should I do? They're all good sisters of mine, and we're here to catch up with me, but I have a different purpose......"

“……”

Looking at the princess's self-blaming face, Li Yuanjia was speechless for a moment.

However, this matter was provoked by him after all, so after the only muttering, Li Yuanjia grabbed the princess's little hand: "Fengzhu, it sounds very reasonable for you to think like this, but it can't stand up to careful scrutiny...... Don't worry, let me ask you first, do you think the Tianzhu number and the content on the six books are easy to use? ”

"This ...... Good. ”

After hesitating, Fang Fengzhu could only nod.

She has a smart temperament, so she naturally understood what her husband meant at once. And even if she knew that Li Yuanjia wanted to comfort herself with such words, but when she asked herself, she really couldn't deny that Tianzhu numbers were indeed much more convenient to use, and the knowledge in the six books of "Mathematics" did make daily mathematical calculations easier.

"So, instead of feeling guilty, I should be happy?"

Tilting his little head and thinking for a while, Fang Fengzhu never turned this corner. It sounded like it made sense, but somehow, she just didn't think it was right.

Although Li Yuanjia also wanted to care about her little thoughts, the fatigue of the day was surging at this time, so he didn't want to bother talking at all, so he directly closed the books in front of Fang Fengzhu and said with a smile: "Okay, don't think about it so much, it's just a few books left and right, maybe that...... Who won't even look at it after taking it back? ”

"This ...... Perhaps. ”

casually echoed a sentence, but Fang Fengzhu secretly shook his head in his heart. She knows her best friend too well, and once she becomes interested in something, she will inevitably think about it before she stops.

However, Fang Fengzhu didn't say it, Li Yuanjia raised his arms and stretched his waist, and continued with a smile: "By the way, Fengzhu, have you had dinner?" ”

"No, no."

After a pause, Fang Fengzhu quickly shook his head.

"Next time there is such a situation, you don't have to wait for me to come back."

Touching the girl's hair, Li Yuanjia chuckled: "I have already instructed them to bring the food here in a while, let's use some as we like and rest early......"

……

While Li Yuanjia and Fang Fengzhu were waiting for dinner, Wei Shuyue had already finished eating.

After saluting her parents, she almost couldn't wait to return to her nest, instructed the maid to light the candles, and took out the set of "Mathematics" that Fang Fengzhu gave her today.

"Tianzhu Digital...... Is it? ”

Stroking the cover of the first volume, she couldn't help but recall the situation when Sister Bong-joo checked the ledger in the afternoon.

With such a thick stack of ledgers, Fang Fengzhu didn't use those calculation tools at all, just asked people to take a pen and a piece of paper, and then write and draw on it, and he understood all the accounts in a pillar of incense!

Until now, Wei Shuyue still clearly remembers her confused state at that time.

As the daughter of a large family, even if her father is notoriously honest, and the family does not have any other property or extra money except for Zhitian and Yulu, Wei Shuyue still has to receive the education of "housekeeper" since she was a child. In addition to knowing how to manage people and how to deal with human interactions, it is also necessary to calculate all the accounts in the family.

In the past, when it came to arithmetic, Wei Shuyue was confident that she would never lose to any woman of the same age.

But this time......

After watching Fang Fengzhu's sister's calculation speed throughout the whole process, Wei Shuyue was shocked, and all that was left was a thick sense of loss. She knew that what she had always been proud of was smashed by that incense stick today!

"Hoo ......"

After a moment of silence, Wei Shuyue exhaled a long breath, bit her lip vigorously, looked at her, and gently opened the first page of the book......
