Zhen Qian took a pig's hair toothbrush and dipped it in green salt and tinkered with it in his mouth for a long time, which was regarded as cleaning oral hygiene, and Zhen Qian was meticulous in this process, but he didn't want to suffer from any dental disease in the Tang Dynasty.

Don't think that there were no toothbrushes in the Tang Dynasty, the toothbrushes in the Tang Dynasty were made of bamboo, bone or jade as the skeleton, a small stick more than ten centimeters long, flat in shape, wide at the top and narrow at the bottom, and inlaid with bristles at the top. Of course, ordinary people can't afford to use it, they can only use wicker to fill the number, if they can't use it, brushing a tooth full of blood is too sparse and ordinary.

The toothpaste of the Tang Dynasty is actually green salt, and in the late Tang Dynasty, the toothpaste with Poria cocos began to be used, and later the ingredients became more and more abundant, including agarwood, sandalwood, dipteroscope, musk, spices, etc., and finally it was necessary to mix it into a paste with cooked honey, which was the ancient toothpaste, also called tooth powder, is it very fucked.

In order to have a healthy tooth and not suffer from dental disease, Zhen Qian pinched his nose and accepted his fate.

I am afraid that it will be difficult for future generations to understand that it can take an hour to get up every day, which is not strange in ancient wealthy families, this is still with the help of Xiaomei, if Zhen Qian does it himself, there will be no need to meet guests in the morning.

"Zhao Yuanwai, Han Yuanwai,...... Keep you two waiting! ”

Zhao Wenshan and Han Guangyu are big landowners in the township near Sendai Village, and their families have nearly 10,000 acres of fertile land.

Zhen Qian didn't deny it, a few families were not far away, and deliberately concealing it would seem rusty, if it really made trouble, Zhen Qian would be passive, so it would be better to admit it generously.

"Disturb ......", Zhao Wenshan, who was full of brains, smiled, and there was no wrinkle on his face in his fifties, known as Smiling Zhao.

"I heard that Zhen Dalang has a secret method that can make the yield per mu reach more than four stones, I don't know if this is true!"

Han Guangyu, who was skinny on the side, was a little embarrassed, and he spied on his family's farming secrets, and Zhao Wenshan was the only one who could be said to be confident.

"The two of them laughed, the yield of four stones per mu is just a false rumor by others, at most only three or four stones", Zhen Qian's land can indeed reach a yield of more than four stones per mu, but this is not all the credit of manure, intensive cultivation can increase the yield per mu, and the use of maifan stone in the farmland can also increase the yield per mu, but these will not tell the two: "In fact, it is not a secret method of farming, but it is just a little more manure in the field, what is the meaning of the two?" ”

Zhao Wenshan and Han Guangyu ran to Zhen's mansion early in the morning, but they didn't come to drink tea and fart, but they didn't expect Zhen Qian to be so direct, but they were stunned for a moment, and sighed: "Zhen Dalang is so blessed, he has such a good farming secret method, I wonder if I can tell one or two?" ”

Han Guangyu was very contemptuous of Zhao Wenshan's naked/naked request: "Zhen Dalang, if the secret method of farming is the secret of Zhen's mansion, I am willing to buy it at a high price, I don't know how?" ”

Zhao Wenshan also knew that he was abrupt, so he changed his words: "A thousand guan ......, I am willing to pay a thousand guan to buy the secret method of farming in Zhen Mansion, and promise not to pass it on to him!" ”

A thousand guan is a million yuan, a bucket of rice is only ten wen, one stone and ten buckets are worth a hundred wen, you can buy ten thousand stone of grain, and the poor family only uses four or five yuan a year, which is equivalent to the money and grain of two hundred households for a year, Zhen Qian didn't expect the two of them to throw a bombshell with one mouth.

But if you really calculate it, there are not many ways to buy Zhen Qian's manure for a thousand times?

Zhao Wenshan and Han Guangyu each have 10,000 acres of fertile land, and one mu of land produces three times more grain, which is 30,000 stones, and taking out 10,000 stones to give to Zhen Qian, it is only one-third of the yield per mu.

Zhen Qian doesn't want to make a one-shot deal, in the future generations, this is a technology patent that will be handed down to future generations, and he can eat and wait to die and eat the old interest.

There was no patent law in the Tang Dynasty, the feudal dynasty was based on agriculture, and there was such a secret method of farming in his hand, which should be handed over to the imperial court as soon as possible, which was the consciousness of a courtier that a good citizen of a feudal dynasty should have.

But Zhen Qian is not a good citizen, not in his previous life, and not in this life.

"Do you two really want to buy the Zhen Mansion Farming Secret Method?"

Zhao Wenshan and Han Guangyu nodded their heads like chickens pounding rice: "As long as Zhen Dalang is willing, any conditions can be discussed?" ”

Zhen Qian took a sip from the teacup, this was not a tea soup in the Tang Dynasty, but a freshly fried autumn tea.

The ancients said: "Spring tea is bitter, summer vegetables are astringent, it should be delicious, autumn white dew (autumn tea)". In fact, due to the development of tea-making skills in later generations, the "bitterness" of spring tea is more sought after and more delicious. The color and taste of autumn tea are between spring tea and summer tea, and the aroma is peaceful, and it is generally inferior to spring tea in terms of nutrients.

In fact, Zhen Qian prefers to drink black tea at this time, that is, fermented tea, which can help gastrointestinal digestion, promote appetite, diuretic, eliminate edema, and strengthen heart function. The flavonoids rich in black tea can eliminate free radicals, have anti-oxidative effects, and reduce the incidence of myocardial infarction. Traditional Chinese medicine believes that tea is also divided into cold and hot attributes, for example, green tea is bitter and cold, which is suitable for drinking in summer and used to cool off; Black tea and Pu'er tea are warmer and more suitable for drinking in winter.

Zhen Qian's face showed a look of pain, and he arched his hand in the direction of the ancestral house and said: "I don't dare to pass on this kind of secret method lightly, so as not to be displeased ...... ancestors."

When the two heard that Zhen Qian had moved their ancestors out, they hurriedly said that they didn't dare, but their eyes still showed greed.

"Please listen to the ...... of a certain slowly coming, although this law should not be passed on lightly, but the world is based on agriculture, and the yield per mu is more than one stone, and the people in the world will have one more way to live, and a certain person can cherish himself with a broom, but it is difficult for the ancestors to ......."

Zhao Wenshan was a little anxious when he heard this: "I don't know if Zhen Dalang has a workaround?" ”

Zhen Qian continued to flicker: "This kind of Tian secret method has also been improved by the past dynasties, and the difficulties in the middle are difficult to describe ......."

Zhao Wenshan thought that Zhen Qian wanted to raise the price, so he gritted his teeth and frowned for constipation: "How about two thousand guan?" ”

"Vulgar, too vulgar...... It's unbearable", is Zhen Qian a person who loves money? At least I will never admit it, I just want to buy a manure production method, thinking that it is a cabbage all over the street!

"It's not a matter of how much money you have, if you insult the ancestors of the Yong family with copper smell, you won't blame someone for turning his face and not recognizing people!" Zhen Qian looked annoyed.

The two didn't know what kind of medicine was sold in Zhen Qian's gourd, and they couldn't hear why, so they looked at Zhen Qian blankly.

Zhen Qian wants this effect, his dream of being a rich man in the Tang Dynasty has just begun, and he hasn't made enough money yet? How could it be easy to sell the secret method of farming to the two of them, and not tear off a piece of meat from the two of them, Zhen Qian would have the surname of the two people.

"I have a law, I wonder if you two are willing?"

"I want to hear about it!"

"Each other is a neighbor, so you don't need to be so polite", seeing that the two of them have taken the bait, it is time to close the net: "Although the secret method of farming cannot be disclosed for the time being, the manure can still be provided to the two, and the two of them are not charged a penny, but how about selling the excess grain in the hands of the two to a certain person?" ”

After a war of words and words, Zhao Wenshan and Han Guangyu found that they couldn't see through the young man in front of them at all, their young and shrewd eyebrows could be used as a whistle, and the old fox couldn't get the little fox but felt indebted to the other party: "Since Zhen Dalang doesn't charge any fees to provide manure, the two of us can't be stingy, next year's grain in our hands will be sold to Zhen Dalang at a ninety percent discount according to the market price, and I don't know if Zhen Dalang wants this year's 5,000 stone surplus grain?" ”

The two knew that Zhen Qian was in the brewing business, and they felt that Zhen Qian's request to buy grain should be so.

Before and after the prosperity of the Kaiyuan Dynasty, many large landowners had a lot of surplus grain in their hands, and the plummeting grain prices could only be transferred to other industries, and the brewing industry became the fastest way to make money.

Zhao Wenshan and Han Guangyu also have their own breweries, but most of the wines they produce are "turbid wine" and "sweet wine", and the price difference between them and Zhen Qian's self-brewed burning knives is ten times. The Tang Dynasty scholars did not like to drink the burnt knives with an alcohol content of fifty or sixty, and a bowl could definitely suffocate the donkey, and Zhen Qian was not ready to seize the low-grade liquor market for the time being, and a large number of burnt knives were sold to the Sogdians who did business from Jingcheng to Youzhou, which attracted the peep of the Sogdians.

The Sogdians were originally an ancient people living in the area of the Amu Darya River and the Syr Darya River in Central Asia and speaking the Middle East Iranian language, from the Eastern Han Dynasty to the Song Dynasty, they were active on the Silk Road, and were famous for their good business in Eurasia.

The end point of the Sogdian merchant was not Tang Chang'an, as is commonly believed, but Youzhou, far east of Asia, and after reaching Tang Chang'an, they went north into Taiyuan and divided into two branches. One continued northward, entered the vast prairie in the north through Daizhou, Yunzhou and other places, and reached Khitan and other places in the east along the southern grassland, and finally entered the territory of Youzhou. The other departed from Taiyuan, crossed the Jingcheng Ancient Road in the Taihang Mountains to Luquan County in Hengzhou, and then went north to Youzhou.

The Sogdians were not good men and women, and they traded in spices, silk, jewelry, curiosities, livestock, slaves, usury, etc., and secretly often trafficked women from the Central Plains to Central Asia.

The secret of the Sogdians' commercial success is due to their mastery of business, their ability to calculate, their undaunted knowledge of various languages, and their ability to do business.

Good at attaching to certain political forces and obtaining a certain political status, which is conducive to the development of business activities. The Sogdians took out a part of the money and grain they earned and gave it to An Lushan in exchange for the convenience of the Sogdians to trade in the towns under their jurisdiction.

It is said that An Lushan's biological father's surname is Kang, his adoptive father's surname is An, and his mother is the Turkic Astrid clan, which is also a foreign family name and has an inexplicable relationship with the Sogdians.

The soju that Zhen Qian sells now is all made by mixing the first pot of wine with the last few dishes, and this kind of soju also makes the Sogdians' eyes glow green, and they sneak into the brewery again and again to steal the secret recipe for making soju.
