On this day, on the bustling streets of Zhuo County, there was a strange shop opened, which was said to be the industry of Bai Shangxian, and suddenly ushered in many people, most of whom were powerful and wealthy businessmen in Zhuo County.

"This little lady, how much does this mirror cost?" A wealthy businessman picked up a palm-sized glass mirror and asked a woman.

The woman smiled slightly, and said in a soft and sweet voice: "This guest officer, this is a glass mirror, an artifact personally refined by Changliu Shangxian, which is a hundred times clearer than the bronze mirror. This mirror is divided into three categories, the first is the ordinary version, the price is between 1,000 and 5,000, the second is the luxury version, the price is between 10,000 and 100,000, and the last is the supreme version, the price is hundreds of thousands to millions of dollars. ”

Hearing that it was personally refined by Changliu Shangxian, the wealthy merchant was slightly startled, and hurriedly said, "Bring me the deluxe version to see." ”

"Okay, wait a minute!" The woman smiled elegantly, and gracefully took out a large mirror from the cabinet, the frame of which was golden silk nan, carved with fine patterns, lifelike, and a beautiful work of art.

The rich merchant couldn't put it down and asked, "How much is this?" ”

"Guest officer, it's 50,000 yuan." The woman still had a bright smile on her face, which made the rich businessman's heart feel comfortable.

"It's so expensive!" The rich merchant sighed and hesitated for a moment.

"Guest officer, this thing is refined by using the immortal method of the fairy world, it is originally a thing of the fairy world, and only immortals can use it, but the immortals who have long stayed on the immortals have mercy on mortals who can't even see their own appearance clearly, so they will present this thing in the world. This is a fairy thing, mortals can use it, it is the ultimate glory. The woman said with a slight excitement, her eyes full of fanaticism.

The wealthy merchant was also driven by this feeling, and his heart was immediately moved, but he still had some concerns in his heart, and said: "However, your introduction says that this item is a fragile product, not as strong as a bronze mirror, and needs to be used carefully." ”

"Guest officer, please rest assured, if it is broken within three years, it can be replaced once, and if it is broken after three years, the mirror can be repaired, but it costs a thousand dollars each time." The woman laughed.

The rich merchant suddenly made up his mind and said, "Well, okay, I'll buy this mirror, well, I'll buy two more for this small one." ”

"Okay, guest officer, it's fifty-four thousand dollars in total."

"Okay, I'll let the house slave send the money right away!" The rich businessman waved his fat hand and said quite boldly.

Now there is no kind of money and ticket number in later generations, and silver tickets can be used for bulk trading, this Han Dynasty era basically still uses five baht money, and there is a large amount of currency, which is the gold cake, but the gold cake also encountered the embarrassment of Archimedes, that is, it is afraid of seepage fake, so it is not popular among the people at all, but it is only common in official transactions.

The rich merchant asked the loyal house slave to go back and carry it, the current five baht money, basically a 3-4 grams, 54,000 yuan, is more than 200 kilograms, if the house slave has not cultivated Bai Ziyun's all-heart true heart method, it is estimated that he will not be able to carry it, and it will take several people to get it.

This scene was watched by a young man not far away, and he looked at the young woman carefully.

The woman was about seventeen or eighteen years old, with a slender figure and a delicate face, and her white and tender little face was not powdered, but her face was radiant, and she had a graceful and noble state.

The young man was secretly surprised, his parents died when he was a child, in order to support the family business, he started business at a very young age, and he has been traveling south and north for several years, but he has never seen a woman with such makeup. The woman's face was immature, slightly unnatural, and obviously nervous, but she did not lose her manners and looked very educated. Could it be a woman from a family?

There are quite a few such women in this store, more than twenty of them, so it can't be that all of them are women from the family, right? How could a woman from a family do such a cheap job?

The young man pondered for a while, and finally saw that some famous people were coming, and that this woman was well-behaved, and should have been specially trained, and that graceful and noble posture was achieved by using guò hair accessories, makeup, and clothing.

The master's beauty and beauty skills here are so wonderful, it is really a strange person in the world, well, it is said that this Baiyun Department Store is the one who has stayed in the immortal Bai Ziyun for a long time, and it is from the hand of this immortal.

"This long-staying immortal, I must see Mi Zhu well." The young man thought excitedly.

This young man is Mi Zhu, a wealthy businessman in Xuzhou. In the Romance of the Three Kingdoms, Mi Zhu may be a very tricky character, but this person is a very important figure to Liu Bei, who gave Liu Bei a lot of help when Liu Bei was at his most down, and made him regain his strength. has made such a great contribution to Liu Bei, and Liu Bei has never neglected Mi Zhu.

Mi Zhu went to Jizhou to buy grain, and after entering Jizhou, he heard the most along the way than to stay on Xianbai Ziyun for a long time. This Bai Ziyun is very miraculous, and his heart is full of curiosity about this immortal, although he is quite old after a few years of experience, but after all, he can't bear the youthful heart, so he ran to Zhuo County, Youzhou.

But he didn't expect to hand over the famous thorn several times, and the Taoist children of Baiyunzhuang were all in retreat with immortals, and they didn't see any guests to refuse. Mi Zhu was helpless, had nothing to do, had to wander the street, today I saw the opening of this Baiyun Department Store, curious, I came in to have a look.

There are indeed a lot of good things in this Baiyun Department Store, and there are even magical things like glass mirrors. However, Mi Zhu is not very keen on this kind of mirror, because this kind of glass mirror is obviously too easy to break, not convenient for long-distance transportation, and expensive, not as good as ordinary porcelain on the road loss does not suffer, once this kind of mirror is lost, it is a heavy loss, so this kind of mirror can not be purchased in large quantities, unless the immortal can completely solve this fragile problem, can be transported to other states in large quantities, or even farther away. (Why mirrors are easy to break, let's just think about the ancient road of the pit daddy, of course, if only a few mirrors are still available for home use, as long as you are careful along the way, Mi Zhu here is considered from a business point of view)

One thing that piqued his interest was a rectangular shape with a thin rod embedded in a wooden frame, and on the pole were strung with wooden beads, two beads on the top and five beads on the bottom.

"Little lady, may I ask what this thing is? What does it do? Mi Zhu asked.

The woman came to the door with business, and immediately said enthusiastically: "Guest officer, this thing is called an abacus, a utensil invented by Bai Shangxian to improve the abacus and abacus, which can perform quick calculations. ”

"Abacus?" Mi Zhu smiled slightly, looking at these beads, it is a bit like an "abacus", the stones in the "abacus" are turned into wooden beads and fixed in series, so that it is very convenient to carry, this idea is very simple, why no one thought of it before?

The abacus is to engrave a number of parallel lines on the board, and place small stones (called "operators") on them to count and calculate, which is somewhat complicated. This method was used in medieval Europe, when the Orient was already using more advanced and simple abacus.

"How do I use this abacus?" Mi Zhu asked curiously.

"Bai Shangxian has designed a mantra to use, please take a look at it!" The woman took out a book and solemnly handed it to Mi Zhu, "If the guest officer buys an abacus, he will give a set of formulas." ”
