Bai Shan knew that there was a good restaurant nearby, which was at the end of the street. Although the time is still early, on a day like today, I am afraid that there are too many people going to the restaurant to eat, so I have to go early. Ou Keren can't go in and out of Sun's Mansion at will like Baishan, and spends most of his time in the mansion, and his eyes are also wandering around, busy looking at some new things. Including the street vendors, they can arouse his interest.

Su You loves the quaint wooden buildings. At this time, the shops, workshops, archways, and pavilions of the ornamental wood carving structure are full of interest.

Bai Shan pointed to a 10,000-bladed shop passing by to show the two, and Su You also knew the 10,000-blade logo on the plaque. Bai Shan also pointed out that the utensils shops and cloth shops in the four seas are not far from the shops of Wandao, and they are indeed old competitors. However, after Wanjian has a mold, it will be difficult for Sihai to compete with Wanjian anymore.

Some of the tools developed by Wan Jian in the Golden City, as well as the Genghu Knife, have already been passed out. Sikai is also an expert in the field of utensils, and they see that it is not difficult to see the great advantages that its improved refining process brings. I believe that Sihai will not just sit idly by, and they will have more drastic means to attack Wan Jian when they are guarded. However, these old and young masters who have their own Ten Thousand Blades Commercial Building have to worry about it.

An antique shop appeared in front, with a mahogany plaque hanging above the store, and three grass-green ancient characters "Le Shufang" written in a very strong and atmospheric font. The name of the inscription is "Qin Cangyue". With these words, Su You felt that this store was not simple, and the area of this store was much larger than the average one, and it was located at the end of the street, so the location was very good.

Su Youchai is a book seller. He is interested in books, which are the fastest way to learn about the world. When he was in the Golden City, he often read books on commercial buildings, but most of those books were related to the utensils industry.

He beckoned them to go in and have a walk. The layout of the store is extremely exquisite, the shelves used are all made of rosewood that Su You thinks, and there are many books on the left shelf of the store, all of which are paper books. On the wooden frame on the right are indeed all kinds of delicate musical instruments, Su You knows zheng, erhu, pipa, flute, flute, etc., but they are all clumsy styles. This shop not only sells books but also musical instruments, so it's no wonder it's called "Music Bookstore".

Su You didn't see a guy coming to greet the guests, and just as he was wondering, a little girl said crisply: "Aunt Ziyan, there are guests here." ”

They saw a man rise from behind the bookcase. This is a young and beautiful woman, it turns out that she has just leaned over to organize her books, and her body is obscured by the bookshelves. She was tall and wore a classical skirt. The top is a grass green short undergarment, and the bottom is a purple dark flower pleated skirt with a swaying skirt. The skirt is short at the top and long at the bottom, bounded by the wide band of the waist belt, which perfectly divides the upper and lower proportions, and makes her whole person light and slender.

Looking at her about twenty years old, her beautiful white face gives people a peaceful and tranquil atmosphere, and what impressed Su You was that she had a quiet temperament with intellectuality, which was the temperament that only people who read poetry and books. This is a particularly impressive woman. Her name is Purple Smoke?

"What are you going to buy, musical instruments or books?" Ziyan looked at the three of them and asked with a smile. Her voice is soft and warm, pleasant to the ear.

Her voice was as soft as a gentle drizzle, and it had the power to make people quiet. Hakusan felt that speaking loudly would ruin the tranquility.

The crisp children's voice suddenly sounded again, breaking this atmosphere, "The instruments in our shop are all made by the best craftsmen of the Qin family, with excellent materials, exquisite carvings, and melodious music. Guaranteed fair price, no bullying! ”

Well, it's a little fellow. Ziyan couldn't help but smile and said, "Okay, Xintong!" Now that you're done, go ahead and do your math. I'm going to check on you in a moment. ”

She was a little embarrassed to say to the three of them: "As my niece Xintong said, our Qin family has been operating musical instruments for generations, and we dare not say that the price is good, but it is indeed worth the money." ”

Su You's heart moved, then her name was Qin Ziyan. He heard Yao Legend talk about the Qin family, Qin Xiaochuan, who once played piano music, and is still the emperor's teacher. Sure enough, it is a family of piano music, and the business it runs is also musical instruments.

"I'm going to read it first, and I really need to buy some books." Su You felt that if he came in, even if he didn't buy the piano, he had to buy a few books, otherwise he would be embarrassed to go out empty-handed.

Bai Shan whispered, "Let's take a look at the instrument first" and stepped into the instrument area. Su You didn't believe that he could play the piano, and he probably had the same idea, so why should he buy something casually.

Ou Keren walked to a zither stand, stared at the black and red, I don't know what material it was, and asked for a moment, "Can I try it?" ”

Su Bai and the others opened their eyes wide, Keren talked about the guzheng?

Qin Ziyan smiled and nodded.

Ou Keren sat on the wooden bench in front of the zither, and gently stroked the body of the zither with both hands, and the hand was smooth and warm, made of fine wood. He pondered for a moment, then put his hands on his hands. The left finger presses the string, the right finger hooks and picks the zither string, and immediately sends out the music like Ding Dong Ding Dong spring water. With the change of his technique, or wiping or sweeping, the music is sudden, like rain hitting plantains. He changed the melody of the tune, sometimes unrestrained mountains and flowing water, sometimes sad and tactful and low, showing a very high Zheng skill.

Su You can also hear that he is not playing the same tune all the time, but constantly changing, showing different genres. Su You admired it, Ou Keren Zheng was extremely good, and he couldn't help but listen attentively.

Look at his hands dancing on the strings of the zither, and look at his cheeks, neck and neck that are immersed in the interpretation of the zither music. Su You had a weird feeling, smiled, and suppressed the thoughts that came to his heart. Glancing at Bai Shan again, seeing that he didn't realize anything, he was just listening to the music attentively, Su You smiled again.

The sound of the zither stops. Ou Keren withdrew his hands, stood up and said, "I haven't played for a long time, and I'm a little rusty, which makes you laugh." ”

Qin Ziyan said: "This brother is a good skill. Ups and downs, inhibitions, changes without direction, the sound of the zither is swirling, and the essence of the zither method has been obtained. The song is more like a story, as if it is pouring out the story in my heart. ”

Bai Shan also praised: "Keren's Zheng song is graceful and melodious, and it smells like a spring breeze blowing through the heart!" ”

When Ou Keren heard the young master's words of praise, his eyes lit up and he glanced at him. Su You remained silent and praised "The aftermath is lingering, endless!" ”

Bai Shan said to Qin Ziyan: "Purple Smoke Girl! I want this kite, but we can't take it away now, can you deliver it? We live in Wanjian Commercial Building. ”

Ou Keren hesitated for a moment, but did not refuse silently, thinking that he liked this zither very much.

Qin Ziyan was stunned and looked at Baishan, "Are you from the Sun clan?" ”

Bai Shan replied, "We are the craftsmen of the Ten Thousand Blades Merchant Building. ”

Qin Ziyan nodded and said, "I happen to know Miss Sun, and I often go to the door, so I'll bring it to you another day." Childe's honorable name? ”

Bai Shan was just about to report his name, glanced at Su You, and reported Su You's name. He thought that Director Su's name would be louder. Su You was speechless.

Bai Shan asked the price and had to pay the money first.

Qin Ziyan said: "I have an old relationship with Miss Sunfu, you are the person of Sunfu Wanji, I will give you a discounted price, three hundred and forty taels of silver." ”

Bai Shan did not make a counteroffer, and paid quickly.

When Su You saw that Bai Shan had bought something, he also looked at all kinds of musical instruments, and he didn't ask about the instruments he didn't know, so as not to understand and make people laugh. Among those small orchestral instruments, he could guess a few such as the gonghou, huqin, and qiang flute, which were the instruments used by the nomads of the steppe. He looked at the rest of the flutes, flutes, and pipas he knew, and he could play some flutes. He actually plays the guitar better, but unfortunately there is no one here, it is an instrument from the West.

Thinking of the West, he thought of the pair of sisters and brothers, and then thought of the imprint on the back of the Yin corpse's head. Hey! Since Westerners can come to the East, can they buy books about Western countries or books in English?

Su You subconsciously picked up the jade flute with a whole body of turquoise. The tentacles are smooth and heavy, this is made of jade, looking at the turquoise and moist, crystal clear flute, is it made of jade? How much does this water-colored jadeite cost, he hesitated and asked.

Qin Ziyan's eyes were unusually shiny for a moment, and he smiled: "After the discount, it is also three hundred and forty taels!" ”

Compared to the wooden zheng, it costs three hundred and four, not only is this jade flute not expensive, but Su You also feels like he has picked up a leak. Maybe the jade of this world is not worth much. He paid for the jade flute, which was small enough for him to take with him.

Su You walked to the bookcase again, picked up a book and flipped through a few pages. Although the books were also paper, the texture was better than what he had seen before, the paper was white, and the font was clear and neat. Isn't this like a hand-copied, printed book? Unsure of when the printing press appeared in this world, he didn't venture to ask.

After reading a few books, Su You found that the books here are relatively miscellaneous, and the categories are also very wide, with literature accounting for the largest proportion. There are several copies of the same book, and some are only one. Su You wanted to find out if there was anything about other countries.

There are a lot of books, and these books are also grouped and placed, and the same kind are put together. But the stacking method is that one book is pressed against the other, the first one is facing up, and the name on the cover of the book can be seen, and the others are pressed underneath. You have to take the top one away to see what kind of book is underneath, so it's very inconvenient to find it.

Seeing that Su You kept moving each stack of books to check the books below, Qin Ziyan said, "What kind of books are you looking for, I'll help you get them." The book is not easy to find when stacked, and only the person who places it will know better. ”

Qin Ziyan politely came up to help.

Su You asked, "Do you have any books about foreign countries, especially very distant countries?" ”

Qin Ziyan was stunned, "Not sure which country you are referring to?" I have here two books that describe the geography of the world and everything in the world, do you want them? She easily pulled out two books that were three fingers thick each, like an encyclopedia.

Su You thanked and took it. One is similar to the World Geography magazine, introducing the regions and customs of each country. The other is an introduction to natural things, including animals, plants, and all kinds of strange things, which is exactly what he needs. He happily bought it, this book is not cheap, it costs eighteen taels a book, so the cost of reading in this world is very high.

Unconsciously came to the little girl Xintong, she was writing on the paper, Su You looked down, and there was a surprised expression on her face. Bai Shan saw that he didn't know why, so he also came closer to watch. There were some strange symbols written on Xin Tong's paper, he couldn't understand what it meant, and he wondered why Brother Su was surprised?

Su You was really surprised, he recognized these symbols, which were Arabic numerals. Xin Tong was doing the addition and subtraction of ten digits, how could he not be surprised when he saw the numbers, and looked up at Qin Ziyan.

Qin Ziyan also looked at Su You in some surprise, "Do you know this number?" Seeing Su You nodding, she said, "This is a new number that only came from foreign countries at the beginning of the year. ”

"Are they called Arabic numerals, too?" Su You hesitated and asked.

"Yes! It's Arabic numerals, but why do you say 'too'? Surprise flashed in Qin Ziyan's eyes.

Su You blurted out, he didn't expect her to be so delicate, and hurriedly said: "It's nothing, it's just wrong." ”

Qin Ziyan did not continue to ask.

Su You took the opportunity to explain, "I also knew this number by chance, I heard that it was a foreign race from the west, and I didn't expect it to spread to the imperial capital so quickly." ”

Qin Ziyan said: "At the beginning of the year, this kind of Arabs in white robes arrived in the imperial capital, and they brought this kind of novel number. After teaching and demonstrating, it is indeed very convenient to calculate, fast and easy. Now it has been promoted in the Imperial Capital Academy, and our Qin family has taken the lead in teaching students in the Qin Academy, and I can't imagine that your Ten Thousand Blades are also being promoted. Don't know the childe's surname? ”

Su You reported his name, and Bai Shan also signed up with a smile, not minding that he had just reported Su You's name, and Keren also said his name.

"How much is this 57+69=?" Xin Tong suddenly asked Su You beside him. She may not be able to ask casually, so Su You casually answered 126. After reporting the number, Su You looked at the questions written in front of Xin Tong and found that there were two wrong answers. asked her how to calculate it, and Xin Tong said that the finger wrench is a stupid way to add up the total number of single digits and add up to the total number of ten digits. If you encounter a sum of more than ten, you will get out of the mess if you want to enter one, and the first two wrong ones are this problem.

Su You picked up her pen and wrote the addition and subtraction operation formula on the paper next to it, aligned it up and down, underlined it, added one digit first, and if it exceeded ten, it would enter one place, click next to the ten digits to make a mark, add ten digits and add one digit to the in, and the number should be written under the horizontal line. On the contrary, if the single digit is not enough to subtract, borrow one from the ten digits and write the number of the single digits. After the ten digits are borrowed, they are first subtracted and then subtracted, and the number of ten digits is written, and the total number is out.

After writing, he wondered how he could use the brush so well. He found that except for the first few writings, which were a little crooked, the back were all very neat digital fonts. It seems that with the font in my head, I will naturally write it in my hands, and there is no lack of rustiness from practice, and this feeling of being able to do it is very wonderful.

Xin Tong's eyes lit up. Although she was only seven years old, what Su You said was simple and easy to do, and she listed it on paper step by step, and she knew it as soon as she heard it. Clapping his hands and exclaiming, "Ah! It turns out that this is the calculation, I will know it all, thank you brother. ”

Sure enough, she quickly calculated a question, and it got faster and faster later, and a dozen questions were written in a few minutes.

Qin Ziyan's eyes flashed with surprise. It is indeed a good technique, not only can it be used for the addition and subtraction of two-digit numbers, but also three, four, and even more digits.

Bai Shan and Ou Keren were confused, they didn't even recognize this symbol.

"Yay! I'm done. Brother is so powerful, why didn't you teach Aunt Ziyan earlier, and let her teach me again. Aunt Purple Smoke, you are so annoying! I deliberately didn't want to write fast, which caused me to waste many days of playing time. ”

She jumped off the stool, looked up at Su You and said, "Brother, are you called Su You?" Brother Su You is so powerful, you will be my uncle in the future, you have to control my Aunt Ziyan hard, who told her to always bully me. ”
