Lu Wen went to the grain line to order the grain, and Lu Xiaoning began to push the camera around the market.

Anyway, for "it", as long as it does not leave the range of 100 meters from Lu Wen, there is no limit, there is no taboo to pass through the wall, and you can even push the camera into the secret rooms of each business to find out.

When I walked through the secret room, I really saw some restricted shots that were not suitable for children.

However, Lu Xiaoning didn't watch much, first, he didn't have a habit of spying on other people's privacy, and second, his girlfriend was still in his hometown, and it was easy to get angry after watching too many goblins fighting.

Lu Xiaoning mainly wanted to find a business that sold sand sugar.

And it has to be a large business, and if the business is small, it is not good, and the small business cannot afford to pay a high price.

Sand sugar is not caramel, caramel is the kind of sugar that melts in the mouth and is easy to stick to the teeth, and the kind of maltose that rural children after the 70s and 80s often exchange waste plastics and palm chips with merchants.

For ancient China, caramelization was a great invention.

Because of the emergence of caramel, ordinary people can also afford to eat sugar.

Before the advent of caramel, sucrose was an extremely expensive luxury in China.

Because the raw materials such as sugarcane for sugar production are limited by the place of origin, the transportation is inconvenient and the price is expensive.

However, the use of rice, barley, wheat and corn as raw materials makes the price of caramels much lower.

Although the Tang Dynasty has popularized caramel sugar, it can still be sold at sky-high prices when it is trafficked to Dashi and Fula, so many Sogdian Hu merchants rely on trafficking caramel to make a profit.

But what Lu Xiaoning is looking for today is sand sugar, that is, sucrose.

Lu Xiaoning quickly found a suitable business name, the Great Qin business name.

This Daqin firm was not only large enough, but also happened to encounter a difficult matter.

At that time, the proprietor of the Daqin firm was discussing with the shopkeeper of the firm to prepare a birthday gift for Colliers.

"Dong Weng, the big thing is not good, the ten-stone black pepper that prepared Grandpa Gao for his seventieth birthday has an accident."

"I already know about this matter, the ten stones of black pepper have entered Yang Jiecao's private treasury, although Li Yuanjun arrested Yang Jiecao and the steward of his house, but did not recover the goods that were stolen by the Yang family."

"As expected, Li Yuanjun didn't dare to tear his face with the right minister."

"But Dong Weng, among the birthday gifts we prepared for Grandpa Gao, the others are ordinary things, that is, these ten stones of black pepper can be worth a few dollars, and now that there is no black pepper, this birthday gift is a little undignified."

"Wait a few days for you to go to Shiguo and see if you can buy a few people and come back."

"Shi Guo was sacked by Gao Jieshuai's army three years ago, and I'm afraid there is not much left."

"It's still hard for you to take a trip, you can buy as much as you can, plus those agate, rhinoceros horn and gold and silver utensils before, you can barely cope with it."

As he spoke, a cheerful footstep suddenly came.

Immediately, a silver bell-like voice came to Lu Xiaoning's headphones.

"Grandpa, grandpa, today is the seventh day of the first lunar month, and the Lantern Festival will be held in seven days, will we also cancel the curfew and hold a lantern festival in Khotan this year?"

Lu Xiaoning subconsciously turned the camera over.

Then Lu Xiaoning felt shaken.

At first glance, it is beautiful, so beautiful.

At a second glance, it is not only beautiful, but also glamorous, really bright and beautiful.

It's the kind of brightness that radiates all over her body, so that men don't have the courage to look at her.

Fortunately, Lu Xiaoning is outside the computer screen, so you can watch it unscrupulously, this little lady is really beautiful, beautiful to see, but it's a pity that it's a Persian orchid!

Lu Xiaoning only found out at this time that Alos, the proprietor of the Great Qin Firm, was a Persian.

This guy wears a hood, wears a Shu brocade round-necked robe, and doesn't have a beard, at first glance he really doesn't tell that he is a Persian, but if you look closely, you can still see it.

It can be seen that Alos is also extremely doting on this daughter, and his face was still full of sadness just now, but as soon as his daughter came in, she immediately smiled toothlessly.

"Leia, Grandpa has asked the town guard, there is no curfew in Khotan City for three days before and after the Lantern Festival this year, every household must hang lanterns, and there will be Aoshan lanterns in front of the palace, and Grandpa will take you to see the lanterns at that time."

"Really? That's great. The girl clapped her little hands and danced with joy.

The girl's lithe body swirled like a butterfly, and her black hair braids floated up.

Lu Xiaoning was also infected by the girl in an instant, and became inexplicably happy.

But a man is a man after all, and he will never forget his true nature no matter what the circumstances.

Lu Xiaoning decisively pushed the camera to the girl's face, wanting to give a close-up of the girl's flowery smile.

It is said that European and American women have large pores, rough skin, and freckles on their faces, so they should only be seen from a distance and not up close.

However, before the camera could advance in front of the girl, the field of vision on the screen suddenly receded, and the speed of retreat was extremely fast, and the surrounding scenery was rustling backwards.

In the blink of an eye, the camera retreated to Lu Wen's approach.

I saw Lu Wen standing outside the gate of a grain number, and he was crossing his hands and whispering: "Is Immortal Venerable here?" ”

Seeing this, Lu Xiaoning understood that the surveillance camera also has the function of automatic reset, as long as Lu Wen wants to find him, it will instantly retract to Lu Wen.

This made Lu Xiaoning feel a little unhappy.

Didn't he really become Lu Wen's summoned divine beast?

"I'm here." At that moment, Lu Xiaoning said angrily, "The grain is set?" ”

"Well, it's been decided, a total of five hundred stone of grain." After a pause, Lu Wen asked cautiously, "It's just that the money to buy grain is ready for Immortal Venerable?" ”

"Don't worry, money is not an issue, you do what I say now."

Lu Xiaoning asked Lu Wen to go to the horse market to buy iron pots, sugar, charcoal, saltpeter, fine gauze and other things for later, and asked him to rent an independent yard in the post house.

Lu Xiaoning didn't plan to make rock candy directly.

Instead, I am going to make a relatively simple white sugar first.

There are records of sugarcane sugar production in China since the pre-Qin period, but it was not called sugar at that time, it was called gluttony.

Moreover, the rice processed from sugar cane is not only dark in color, but also extremely expensive, only the nobles can afford to consume it, and the common people can only eat the caramel candy.

The sugar making process sent by Tang Taizong to retrieve from Tianzhu is also the brown sugar boiling method.

To this day, India still retains the thousand-year-old process of boiling brown sugar.

That is to say, until the Tianbao period, there was no granular white sugar in Datang and even in the whole world, so it was completely possible to earn the first pot of gold with white sugar.

As for rock sugar, one is that the processing time of rock sugar is too long, and the other is that the process is slightly complicated, so it is better to leave it for the future, and now it is just a matter of changing some grain, and the production process of white sugar is enough.

When Lu Wen got everything ready, Lu Xiaoning began to teach him step by step.

The process of white sugar is actually very simple, that is, the adsorption function of activated carbon is used to remove the pigment in the brown sugar solution, and then the impurities are filtered with fine gauze, and then cooled and crystallized to become white sugar.

In order to shorten the time for cooling precipitation, saltpeter is also used.

It was busy until seven o'clock in the evening, and the first packet of white sugar finally precipitated.

"This is the treasure that Immortal Venerable said?" Lu Wen looked stunned.

"Don't underestimate this white sugar." Lu Xiaoning said, "You don't think it's unusual, because you know the process, you know that you can make white sugar from sand sugar through simple processing, but people who don't know will only think that white sugar is precious, because white sugar is not only very sweet, but also white as frost, very beautiful." ”

Lu Wen was still a little hesitant, and said in his heart how much money can this thing be worth?

Lu Xiaoning didn't explain, and said: "You take the white sugar to the Daqin business, tell the shopkeeper of the Daqin business, let them prepare 500 stone grain, 200 barrels of stone grease, and hire a camel team to send it to Selüburg, you will share the production process of white sugar with them, and the profits will be divided equally in the future." ”

The craft also shared these words, and Lu Wen could barely understand them.

But Lu Wen felt that it was impossible for the Great Qin Firm to be so stupid.

Just such a method, and ask people to exchange 500 stone of grain plus 200 barrels of stone grease?

Moreover, he asked people to pay for a camel team to send to Cyruburg, and the shopkeeper of the Great Qin Firm would definitely not agree unless he was crazy, there was no doubt about it.

"Do as I say, and go now." Lu Xiaoning said again, "It's almost time for curfew." ”

"Whoa." Although Lu Wen was suspicious, he still left the post house with the freshly baked white sugar according to the decree of Xianzun and went to the horse market, and soon found the Daqin business.
