Li Xiao would not do it when chopping wood and burning charcoal. Not only does he work hard but he can't make a lot of money. It is impossible to rely on chopping wood and burning charcoal to make a fortune.

There is a saying that there is no selling vegetables for ten miles, no selling woodcutters for a hundred miles, and no selling bamboo for a thousand miles. This means that several businesses that could not be done under the conditions of transportation in ancient times were not sold. Vegetables did not sell them ten miles away, woodcutters did not sell them for a hundred miles away, and rice did not sell them for a thousand miles away, because the transportation cost alone could not bear it.

Although Lanxi is only eighty miles away from Chang'an, if you have to chop firewood and burn charcoal, you can go deep into the mountains of the Qinling Mountains. The mountain roads are curved and the roads are long and difficult. You can chop firewood and burn charcoal. After burning it, you have to find a way to transport it to Chang'an to sell it. After a while, you really can't make a lot of money.

After supper, there is no nightlife.

After roasting for a while, everyone went home.

Wanniang burned water for Li Xiao to wash her face and feet in the fire pit, and she was extremely gentle and considerate.

Without lighting the lights in the house, I shoveled some charcoal fire from the fire pit and placed it in a broken pottery basin by the bed, which was used as lighting and heating.

Sitting on the bed, Li Xiao was still a little awkward.

I told a story all night last night, and it was finally dawn. But what should I do tonight?

Just when he didn't know what to do, Zhao Wan said to him shyly, "Mr. I can't serve you tonight."

"What's wrong?" Li Xiao thought she was uncomfortable, but she hummed for a long time before she explained the reason. It turned out that she had an aunt.

After listening, Li Xiao felt relieved.

It’s so wonderful to come. It’s really the right time to come to my aunt at this time, but it’s a relief to his embarrassing situation. Otherwise, I couldn’t be newly married and wouldn’t have been reconciled for a long time. Won’s mother wouldn’t be sad? Now, I’m here, I’m here, this is force majeure.

"Then you have to have a good rest these days, don't be too tired, especially don't get cold water or go out to blow the cold wind."

"Drink more boiled water. By the way, when I go to the street to buy food tomorrow, I will buy you some brown sugar and drink more brown sugar boiled water."

Wan Niang is both shy and heartwarming, and her husband is so considerate to her.

"My husband, it's okay, it's just that these few days are not very convenient. It's only a few days to endure. Don't buy candy, it's too expensive."

After Wan Niang said this, Li Xiao remembered that sugar is indeed very expensive these days, especially sugar. He asked Wan Niang carefully for a while and it turned out that sugar is really a luxury item nowadays. The more sugars on the market are sugars such as honey sugar and maltose, which can only be eaten by noble families.

At this time, the sucrose was generally called sand sugar, also known as froscoop. This sugar was actually a sugar production technology that was improved in Zhenguan. It was originally a kind of sucrose tribute paid by the Moji country in ancient India during the Zhenguan period and was loved by the palace. Emperor Li Shimin sent an envoy to Moji country to seek the method of making this sand sugar. After obtaining this sugar-making method, people studied and improved it. Local officials in Yangzhou tried to produce sugar cane, and the sugar they finally obtained was far better than that produced in Moji country, so there was the froscoop, sand sugar, which is now very popular among the aristocratic upper class.

"Is the sand sugar yellow?" Li Xiao was very surprised.

According to Wan Niang, the frosting sugar in Chang'an is mainly produced in Lingnan. The weather there is suitable for growing sugar cane. The frosting sugar produced tastes good, but this kind of frosting sugar is not the white sugar that Li Xiao originally thought.

Sucrose is sucrose, which is used to evaporate the heat energy of fire to make sugar. However, neither Mojie nor the Tang Dynasty today know how to better refine and make sugar.

The best frosting sugar is just yellow granulated sugar. In fact, it should be called yellow granulated sugar. It cannot be called frosting sugar at all, let alone white sugar.

As for brown sugar, there is no such thing as yellow sugar, which is black in color.

There is no white sugar or brown sugar now.

Even if the current queen comes to my aunt, she will not be able to drink brown sugar water after dysmenorrhea.

Li Xiao thought something and felt that he had found a new way to make a fortune.

White sugar was a very common thing in later generations. In fact, in ancient China, sugar cane was used to make sugar very early. As early as the Spring and Autumn Period and the Warring States Period, there was jujube, that is, dilute liquid sucrose. Later, there was stone honey, which was a relatively viscous semi-solid sucrose.

After the Jin Dynasty, sugar was taken as sugar, which was the crystal sugar with a gravel-like appearance, and the color was black. Now, the frosting sugar produced by the Tang Dynasty absorbed the technology of Mojie and other countries. The color was yellow and the technology became stronger and stronger.

From black sugar to yellow frosted sugar, it also reflects the standard for people's value in recent years, that is, the whiter the more valuable it is, and the whiter the more popular it is.

Yellow sugar is more popular and more expensive than black sugar. If it can be extracted, it would be even more amazing.

The key to frosting sugar lies in the fact that there is a complete set of sucrose purification and decolorization processes.

At this time, the frosting sugar in Datang used drip method to decolorize sugar. Boil the sugar juice to a considerable concentration and pour it into a funnel-shaped pottery called Waliu, and drizzle it with yellow mud.

In essence, yellow mud is used as an adsorption decolorizer to extract white sugar, but this method is not advanced enough. The frosting sugar produced is actually not white enough, but yellowish yellow-white.

But even so, this not-white frosting sugar is still the most popular and most expensive sugar on the market today, which is much more expensive than maltose and honey sugar.

Now a dou of japonica rice costs 11 cents, while a dou of salt costs 110 cents.

And what about frosting sugar?

The price is ridiculously expensive. If you buy one tael of silver and three kilograms of sugar, you can tell how expensive it is. The gold and silver of the Tang Dynasty are not direct currency, but are mostly used as rewards, and the silver output of the Tang Dynasty itself is also extremely low.

In gold and silver shops on the market, one tael of silver can now be exchanged for about 1,600 cents.

Buy three pounds of frosted sugar for one tael of silver, and one pound of sugar costs more than 500 yuan. This price is twenty or thirty times that of salt and more than 200 times that of rice.

It costs more than 500 cents to buy a pound of candy. If you buy corn, you can buy more than 200 cents per bucket, which is enough for everyone in the village to eat the food for a winter.

"Wan Niang, how much is the cheapest sand sugar per pound now?" Li Xiao was energetic. If he bought some brown sugar with insufficient purity and then purified and processed, it turned into white sugar and sold it. It must be a way to make a fortune.

"The cheapest sand candy? The cheapest one should be the white color and black sand candy, but it is not cheap either. You can buy ten kilograms for one tael of silver."

"The difference is more than three times, it's profitable." Li Xiao smiled while pinching his chin.

“What profitable?”

"Wan Niang, let me tell you a secret. Actually, I have a secret recipe that can purify black sand sugar into frosting sugar. Let's buy black sugar, purify it into frosting sugar, and you can sell it three times by replacing it."

Wanniang opened her eyes wide in surprise, "Don't joke, my husband, how can you do this?"
