Oh? Apart from me? Lin Wanrong couldn't help but suck in a breath of cold air. Did Old Xu mean that there was a hidden meaning in his words? I don't have a problem with you having ideas about me, but the key is that your girl and I don't get along.
Grand Mistress saw Xu Wei and Lin San talking and saw Miss Xu's miserable face, so she pulled her hand and said, "Sister Xu, Miss Su, Lin San has a rotten mouth. Let's not listen to his nonsense. Come, let's go in. I have something good for you. "
Lin Wanrong knew that Grand Mistress was going to give out perfume and couldn't help but laugh. Grand Mistress's face turned red and she glared at him. She took the account book and pulled the two women into the inner courtyard.
"Little Brother Lin, Little Brother Lin, can you hear me talking to you?" Xu Wei's voice rang in his ears.
"Ah, haha, I heard, I heard, that something — —" He laughed and said, "Mister Xu, let's talk about this later. Look at this portrait first. Do you know this woman? "
He took out a portrait from his bosom and handed it to Xu Wei. Old Xu took the portrait and saw that the brushwork was unique. The edges and corners were concise. It was a woman who floated like a fairy. Her expression and appearance were stunning. He looked at it carefully for a while and frowned, "I seem to have some impression of her, but I can't tell where I've seen her."
Lin Wanrong was overjoyed. He grabbed his arm and said, "Mister Xu, think again. Have you seen her in the palace?"
Xu Wei shook his head and said, "I only seem to have some impression of her. As for whether I've seen her or not, I'm not sure."
Lin Wanrong said, "Then, have you seen the current emperor's second princess?"
Xu Wei smiled bitterly and said, "Second princess? I saw her when she was young. For the past ten years, she has lived in seclusion and kept a low profile. The only person who has seen her is probably the emperor. I am very familiar with the eldest princess, but the eldest princess and the second princess have only met a few times. Sigh, this is related to a secret when the emperor ascended the throne. Let's not talk about it. "
Lin Wanrong said, "Then Mr. Xu, take another look. Does this young lady look like the Eldest Princess or the Emperor?"
Xu Wei took a look and said with a smile, "Brother Lin, you asked me so many questions. Could it be that the person in your painting is the Second Princess?"
Lin Wanrong nodded and said, "I'm not too sure either. I just have some suspicions. If this is really the Second Princess, then she should be somewhat similar to the Emperor or the Eldest Princess."
Xu Wei shook his head and said, "Although a person's appearance is derived from his parents, it is also greatly different from his parents. It was too biased to judge blood relations based on appearance alone. It was even more so for the royal family. Of all the princesses of the past dynasties, there had never been anyone ugly. Why was that? Because the Emperor had a dignified aura, his appearance would definitely not be too bad. As for the concubines, their appearances were even more beautiful. As a result, the princesses they gave birth to gathered the good points of their parents, and most of them were exceptionally beautiful. Because the majesty of the Emperor was not suitable for women, most of these princesses inherited their mother's appearance. For example, the eldest princess inherited her mother's appearance, and so did the second princess. These two princesses are half-sisters, so it's normal that they don't look alike. "
Lin Wanrong was a little disappointed. If Qing Xuan's appearance was similar to the eldest princess or the Emperor, then it would be much easier to judge. However, Old Xu threw out a remark that "the appearance of the royal princesses all took after their mothers." It seemed that it was really difficult to find out Qing Xuan's identity just by looking at her appearance. Did he really have to make some more contributions and wait for the Emperor to open his golden mouth and invite him into the inner palace?
Seeing that he could not find a breakthrough from Old Xu, Lin Wanrong was also quite helpless. Qing Xuan, Qing Xuan, are you a princess or not?
The two of them continued to chat, and Lin Wanrong evaded the topic of joining the army. One moment, he said that the border was very far, and the next moment, he said that our army was very strong. He kept talking about irrelevant things. Xu Wei was extremely depressed. After talking with this kid for a long time, he still could not figure out whether he wanted to go or not. The first scholar met the first slippery fellow, and there was nothing he could do.
When Lin Wanrong and Old Xu entered the inner courtyard, they saw Su Qinglian and Xu Zhiqing holding a bottle of perfume each and fiddling with it curiously. Miss Xu's complexion seemed to be much better. She applied some perfume on her wrist and sniffed it lightly. A hint of joy appeared on her face. "It's indeed fragrant but not strong, charming but not out of the ordinary. Good sister, this is really good stuff. I like it very much. Do you have any more? I want another bottle of orchid. "
Sweat, she's holding a bottle of rose, and she wants another bottle of orchid. Which style does this girl like? Could it be that she's sometimes pure and sometimes flirtatious? This extraordinary lady's taste is indeed different, very similar to mine.
Su Qinglian smiled. "Zhiqing, this perfume can't even be bought in Hangzhou. The price has already increased several times. A small bottle like this has already been hyped up to three hundred taels of silver. The madams and young ladies in the capital have also started to circulate about it, but there are too few of them, and very few people know about it. Everyone cherishes it. You're asking for a few hundred taels of silver right away. "
Xu Zhiqing smiled. "Aunt, of course I know. This is the first time I've met Younger Sister Xiao Yuruo, and she's already so generous. If I don't ask for another bottle, wouldn't it be a loss? Moreover, Younger Sister Xiao Yuruo is also a smart person. She wants us to promote her perfume. "
The Grand Mistress was naturally delighted to see that a virtuous lady like Xu Zhiqing was so fond of this perfume. She smiled. "It's fine, it's fine. I'll gift Sister Xu and Miss Su each a bottle of orchid. This was brewed by our Lin San's secret method, and you can't find it anywhere else."
Miss Xu glanced at Lin San and acknowledged him with an indifferent "Oh." Lin Wanrong rubbed his nose and thought, 'I thought you would return these two bottles to the Grand Mistress after hearing that it was my perfume. According to the black market price, this is six hundred taels of silver.'
While he was pondering, he saw Xu Zhiqing slowly walking over with the Grand Mistress's account book. "Young — Young Master Lin, I have something to ask you."
When Xu Wei saw his daughter talking to Lin San, he immediately laughed and said, "The two of you are quite knowledgeable, so you should chat more. Grand Mistress, this old man will stay in your residence today and ask for a cup of wine. Qinglian, go get the zither. I'm in a good mood today. Let's sing a little song and have some fun with Grand Mistress Little Brother Lin. "
'Damn, I'm just talking to your daughter and you're singing and dancing, drinking and eating good food. I'm the one doing the hard work, and you're the one enjoying it. Is there any justice in this world?' Lin Wanrong laughed. "Ah, Miss Xu, do you want to ask? Later, I also want to listen to Miss Su play the zither. Sigh, speaking of which, I also like to talk about love, but I'm not good at it. I haven't gotten many. "
Xu Zhiqing lightly nodded. "I originally wanted to ask Young Master Lin about Arabic numerals, but since you don't have the time, then forget it."
Lin Wanrong was shocked. "You know Arabic numerals?"
A cunning light flashed in Xu Zhiqing's eyes. She smiled. "Let's listen to Concubine Su play the zither first. Doesn't Young Master Lin like it?"
'Damn, this girl is purely taking revenge. I'll talk about love with you today.' He laughed. "If that's the case, then forget it. Sigh, I originally wanted to discuss the calculation method of Arabic numerals with Miss Xu. Let's talk about love, let's talk about love!"
Both of them had ulterior motives and were secretly competing. It was a competition of patience, to see who would surrender first.
After walking a few steps, Lin Wanrong remembered that he wanted to spread Arabic numerals around the world. Although this was a basic subject, if it was done well, it would definitely benefit the country and the people. Perhaps China's pace of catching up to Europe would start from here?
'I don't know how to make cannons, nor do I want to make gunpowder. But if I spread the basics of mathematics and science, it would be a matter of benefit for generations to come. Forget it, I'll be an unsung hero. 'Xu Zhiqing has perseverance and perseverance. She also knows Arabic numerals. Why should I waste this opportunity just to be angry?'
Thinking of this, he suddenly stopped and said seriously, "Miss Xu, I won't be angry with you. Let's have a good talk. No matter what you think of me, whether I'm talking nonsense or ignorant, I want to say that this Arabic numerals and the calculation method based on this time is an extremely great invention. Without it, there would not be the strength of the Westerners. With it, Da Hua will usher in a brand new era. "
Xu Zhiqing saw that his expression was very serious. He seemed to be a different person from the young man just now. She could not help but sigh, "How can you change so quickly? This Arabic numerals was spread by the Westerners. There were records on the coast. I also saw some records in the miscellaneous books translated by the New York missionaries. Today, I saw that you used Arabic numerals in the account book of the Grand Mistress. I was curious, so I asked, is this Arabic numerals really as powerful as you say?"
"Whether it's powerful or not, it's not up to me. How about this, you come up with a math problem, and we'll calculate it together to prove it." Lin Wanrong said.
This was indeed fair. Xu Zhiqing nodded, thought for a moment, and said, "Then I'll come up with a question. There are ten squares on a chessboard. The first square is one tael of silver, the second is two taels of silver, the third is four taels of silver, and so on. To fill all ten squares, how many taels of silver would it take? "
Miss Xu took a pen and paper to calculate. Lin Wanrong calculated in his mind, smiled, and said, "There's no need to calculate. One thousand and twenty-three taels of silver."
This question was set by himself, and he could not cheat. Miss Xu was shocked, and said, "How did you calculate it? Is this the calculation of Arabic numerals? "
Lin Wanrong laughed, and said, "I can't tell you now. When you learn how to use Arabic numerals, you can deduce these formulas yourself. Miss Xu, you are very knowledgeable. Can you tell me the calculation method you are currently using? Do you think it's convenient?"
Xu Zhiqing thought for a moment, and said, "I didn't think it was complicated in the past, but it seems that I have to reconsider this problem."
Lin Wanrong nodded, and said, "Let me tell you, whether it is the astronomical calendar or engineering calculations, Arabic numerals are the most useful calculation method. If you want to learn, I will teach you this method. I don't expect you to remember my kindness. I only hope that you learn this well, and teach it to more people who are interested in mathematics and engineering to join. Everyone can pool their ideas, and carry forward mathematics. If possible, compile it into a book, and pass it down. With these, I am satisfied. Why are you looking at me? Do you think I am great? Let me tell you, don't do personal worship. I am afraid there will be problems. "
Xu Zhiqing shook her head, and smiled, and said, "You … I just thought you were a bit serious, but you changed again. I will remember what you said. In fact, this is what I have been doing." Lin Wanrong was determined to pass down this method of calculation. Facing a student like Xu Zhiqing, he was very meticulous in his explanation. Unfortunately, he had never been a teacher before, so when it came to elementary school mathematics, he did not know where to start. Fortunately, glib talk was his forte, so he was able to make do with it.
This Xu Zhiqing was really smart. She was already familiar with these Arabic numerals. Lin Wanrong only explained the four calculations once, and she understood it. This made Lin Wanrong secretly speechless. This girl is much smarter than I was in elementary school.
Seeing that she was so eager to learn, Lin Wanrong decided to go all out and teach her the exponential calculation as well. Regardless of whether she understood it or not, he would teach her first. In this situation, he could only force her to learn. If she wanted to understand, she would have to slowly study it after class.
After half an hour, Lin Wanrong's mouth was dry. Xu Zhiqing sighed, "These Arabic numerals are really exquisite. With these methods, Da Hua Arts and Crafts will definitely be able to advance further. "
Lin Wanrong nodded, and said, "Miss Xu, how much did you memorize?"
Xu Zhiqing lowered her head, and her face was a little red. She said softly, "I only memorized 90%. There is still the last exponential calculation that I have not mastered."
Damn, she really is a genius. If I continue, I will have to prove the Pythagorean theorem for her. That's enough, that's enough. My task is done. The rest is up to her.
He had met Xu Zhiqing a few times, but it was the first time he saw her blushing. He could not help but smile, and sighed, "Sigh, just make do with it. Among all the students I have taught, you are the slowest to comprehend."
Xu Zhiqing was not someone who would be easily fooled. She looked up and smiled, "You don't even blush when you lie. However, I am curious. You are not considered smart. Where did you learn the knowledge of Arabic numerals? "
Damn, I am not smart enough. Which eye did you see it with? Lin Wanrong said angrily, "I will tell you when you think I am smart enough. I am hungry. Let's go eat. "
Xu Zhiqing was stunned for a moment, and then she giggled. Her voluptuous body trembled, and she could not even straighten her waist …
