Thirteen thousand camels entered the territory of the Tang Dynasty, and the first commercial event triggered was the collapse of the price of camels.

After these camels have walked more than 10,000 miles with heavy loads, the load on their bodies has reached the limit, and it is no longer realistic to let them walk more than 10,000 miles back to the river, to return to Persia, and to return to the Great Eclipse.

So, the caravans from the river, Persia, and the Great Eclipse, while selling their camels, were also exchanging for a large number of camels.

Camels that could not travel long distances could be exchanged for merchants who took short distances, and camels that were severely injured were bought as meat ingredients in the large canteens.

This is something that cannot be helped, although the camel is known for its hardships and hard work, but unfortunately, the distance it travels is too long and too hard.

Therefore, the loss is enormous.

However, the exotic goods brought to Chang'an by these merchants were warmly welcomed by the Tang people.

Among them, the most popular among the Tang people in addition to frankincense and myrrh, is to Suhexiang, ambergris, rose water is the most popular, especially Suhexiang can be used to smoke clothes, smoke tents, women like the most, so that a spoonful of Suhexiang is more expensive than gold.

The big cannibal also brought a spice called chicken tongue incense, but anyone with bad breath can spit out the fragrance of chicken tongue in their mouth, and they don't have to worry about bad breath.

Gemstone jewelry, gold ornaments, gold utensils, silver utensils, and are also the traditional goods of the Great Cannibal.

However, the fastest and best selling are dates and pistachios, the former is equivalent to a mouthful of sugar, and the latter takes a bite, and the oily aroma of nuts will make people addicted.

The above goods can sell very well, in Yun Chu's expectations, he didn't expect that the blank parchment rolls brought by the big cannibals could be popular in Chang'an, which he didn't expect.

The parchment roll is made by splitting the parchment into three layers, removing the grease, and then concocting it in a secret way to become a soft parchment that can be written.

The Great Cannibals were very good at business, and their parchment rolls were sold cheaply, but the ink written on them was extremely expensive.

Because ordinary ink could not be written on parchment scrolls at all, parchment roll ink was specially made, and they suggested that the royal family use gold as ink, ministers used silver as ink, and ordinary people used black iron as ink.

No one knows where these metal inks come from, but Yun Chu saw some clues,

The black iron ink they used to display was not marked on the parchment scroll, but after a while the ink would appear on the parchment.

This is obviously not an acidic reaction, or an alkaline reaction, gold and silver should be gold powder and silver powder plus glue, nothing unusual.

After Yun Chu and other Chang'an people used up the metal ink of the big cannibal, they could also open a small ink workshop to earn a little fat powder money for their wives.

To say that the person with real business acumen turned out to be this guy Tongpan, he begged Yun Chu to help him sell back three slaves who could write and read from the caravan of the big cannibals for a lot of money......

Ten days later, he took the printed scriptures written by the Prophet Muhammad and sold them to the cannibals.

The cover of the book is the green that the big cannibal likes, and the atmosphere is quaint, and the packaging of the whole book is even more exquisite, especially the gilded title on the cover of the parchment roll, which feels sacrosanct when it looks like it.

He also learned to do business with the Great Cannibals, and made this kind of scripture into three specifications: the high-level ones were sold to the noble, the medium ones were sold to the ordinary wealthy, and the low-class ones were sold to the poor.

I don't know what others think, but the chief envoy of the great cannibal, Hashem, and the deputy envoy Said, saw the model scripture brought by Yun Chu, and his hair stood on end with excitement.

On the spot, he ordered 1,000 copies of the best scriptures, and Saeed ordered 10,000 copies of the best books.

Both of them are scholars, and those exquisite things in the Tang Dynasty are not important in their eyes, but these precious scriptures are hard to find.

For this reason, Hashem and Saeed deliberately spent several days correcting the errors in the scriptures.

The two of them even deliberately engraved a line of gold characters on the title page of the scriptures in order to show their exploits in the Tang Dynasty-Although learning is far away in China, I also seek knowledge.

Because of the arrival of giant caravans in the river, Persia, and Dashi, merchants from all over the Tang Dynasty also arrived.

When these merchants came to Chang'an, they naturally did not come empty-handed, and they also brought specialties from all over the world.

All of a sudden, Chang'an's commerce flourished more than ten times, so much so that the historians recorded in the book: "If you don't leave Chang'an, what you can get from the world is at your fingertips." ”

In 10,000 years, the officials of the two counties of Chang'an were about to go crazy, and the new chief secretary Liu Yuanshou had red eyes, and he didn't know how long he hadn't slept for a long time.

Zhang Jia, the county leader, sent a steady stream of taxes to the treasury of the two counties of Chang'an for ten thousand years.

As for the flowing water sign in Qujiang, there are countless businessmen who look at the flowing water sign that is updated every moment with a stick of incense, and they are even more hoarse and roaring, until the golden bell next to the flowing water sign rings, everyone will collapse to the ground, frantically drinking water to moisten their throats.

The flow sign has stopped updating, but they can't stop, they still have to study the trend of today's trading, and predict tomorrow's trend.

In this case, Datang's calculations have long been unable to meet everyone's calculations, and Yun Chu was surprised to find something he was very familiar with - abacus!

Yun Chu could swear to the sky that he had never revealed the abacus to anyone, however, this thing actually appeared in front of his eyes.

The abacus came out, but the corresponding formula did not appear, so Yun Chu picked up the square abacus in the eyes of everyone and replaced that person to calculate today's trading inconsistencies.

Speaking of planning disk, Yun Chu really has something to say, he didn't plan to disk before, after graduating from college, his girlfriend entered the banking system, God knows why in that era when computers have been popularized and can no longer be popularized, the bank requires bank staff to be able to plan disk, not only will, but also hardware requirements.

Therefore, his girlfriend's abacus is like, but his abacus skills are solid enough to go to the bank to apply for a president.

Yun Chu pulled it all the way, and finally came up with a string of numbers, and more than a dozen accounts next to him took a long time to calculate it, and finally summed it up with Yun Chu's answer, and found that it was not right.

Yun Chu, the power of the county zun in Qujiang, naturally has nothing to say, and the fault can only be the group of tents, so after seven or eight calculations, the answers obtained by the tents finally coincided with the answers of the county honor.

So, Yun Chu directly made the abacus mantra public.

Yun Chu thought it was a small thing, but it turned out to be nothing different from what he thought.

Di Renjie, who came to Qujiang to watch the excitement, knew that Yun Chu was wantonly spreading his own knowledge, and bent down to salute Yun Chu, and then scolded him for being a stupid pig.

After Wen Rou learned of Yun Chu's actions, he decided to stay away from this kind of fool in the future, this is no longer a matter of plucking a hair to benefit the world, but a feat of plucking his own hair to benefit the world.

After Liu Renliang learned of this, he immediately sent this book to the emperor, telling the emperor the importance of the abacus formula, and also emphasized that this is a milestone in the Tang Dynasty's arithmetic, and it is necessary to reward Yun Chu's noble character of not being self-interested and benefiting others.

When he returned home, Yun Chu knew that Yu Xiurong had already fainted from crying twice.

In the past, Yun Chu was also a loser, and he liked to use his own money to help the people of Jinchangfang get rich, and used his reputation as a guarantee to make Chang'an's tattered Fang City a new Xinfang City.

When talking about these things, Yu Xiurong was full of pride, and whoever said that Yun Chu was a loser, she would turn her face with whom.

Obviously, this time is different, since she heard that her husband made her arithmetic knowledge public, Yu Xiurong's tears have not dried.

When I went home at night, I didn't have dinner, not because Yun Chu didn't have dinner alone, but because no one in the whole family had dinner.

Yun Jin was holding a piece of cake and gnawing on it, and said to Yun Chu while gnawing: "Grandpa, Auntie said that you are a loser." ”

Yun Chu picked up his son, and the father and son casually messed with their stomachs with a piece of cake, and went to see Yu Xiurong, who heard that her husband had fainted again when she came home.

At this time, there were many people in Yu Xiurong's bedroom, including Di Renjie's wife, gentle wife, and even Liu Renliang's wife, plus Cui's and Cui Yao, Yun Chu just entered the door, and a group of women glared at him angrily.

And Yu Xiurong fell on the bed with a pale face, and twitched from time to time, completely looking like he was dying.

Seeing that Yun Chu had returned, the wives of the three people left, and when they left, they all looked at Yun Chu deeply, as if they had never known this person before.

After everyone left, Yu Xiurong got up, looked at Yun Chu and said, "You have taught others everything you know, in the future, what will your son rely on to eat?" ”

Yun Chu lifted Yu Xiu's head and looked at it, "What to learn?" He will have something to learn from in the future. ”

"What is your best arithmetic? You have already given it to others, Yun Chu, I won't say a word when I take the money out, I will only be proud that I have such a generous husband.

Now, you have taken your children's things to be generous, this is your mistake, and I ask you, where do you put me, your children, and the ancestors of the Yun clan? ”

Yun Chu moved Yun Jin over and took a look, stupidly didn't pull a few, just threw it away, and picked up Yun Jin to take a look, the little girl had good eyebrows and eyes, kissed it, and finally saw the youngest son Yun Luan pouting his ass and crawling on the bed, so he jumped up and took a bite on the child's pink buttocks.

Only then did he look at Yu Xiurong and said, "What are you learning?" Of course, I want to learn some advanced knowledge, in order to wait for the children to grow up over the years, do you know how hard I have held back?

An abacus mantra is just a fart, your husband's stomach is about to overflow, a lot of knowledge, just like a stomach, the abacus mantra is not holding back, a small part of himself slipped out. ”

Yu Xiurong saw that Yun Chu was blowing fiercely, although she disagreed with her husband's comparison of learning to a sparse knowledge, but after so many years, her husband is still very reliable, that is, he refused to admit it in the matter of kissing the singer by the Baqiao, and the rest of the time was very reliable.

There is one more chapter before 12 o'clock.
