Fan Jingjing used to be a rich man.

She is used to living a life where she can go anywhere with money, and she can't do it without money.

After coming to Datang, she thought that she couldn't move an inch without money, so she actively wanted to get money, and all the production itself was to get money.

After seeing the pastry shop in Chang'an City, Fan Jingjing returned to the suburbs of Chang'an to continue working and earn the satisfaction of materials.

After Fan Jingjing got enough money from Niu Shijin, she was greatly satisfied with food and materials.

She also managed to get Niu Yingxiu and Li Lizhen to sneak around with her and get a small cabin.

It's just that it can shelter from the wind and rain, and there is not even a compartment.

Such a small cabin, the escort of these people, can be completed in an hour.

The most important thing is that the suburbs are too dangerous, and without the company of adults, the two children cannot come out more, nor can they stay for a long time.

It was different from the attitude of the adults in the family who were originally in the royal manor.

"The house is sturdy ......"

Fan Jingjing found an old woman and an old gentleman who had no children and grandchildren to support from the neighborhood, Wang Tongyan and Yao Chang.

Speaking of old age, the two of them are not old, they are only in their fifties, but they look gray, and their hands and feet are quite flexible, but one of the old man's hands is numb.

I heard that it was a defense against a bandit invasion.

They usually grow some food on their own and rely on the village to make a living.

In the Tang Dynasty, even the strong laborers could barely mix food and clothing, and the old man's little thin field was still sympathetic to the landlord's family and cultivated for him, and he didn't even harvest much land, but the land was not good land and the productivity was low.

Fan Jingjing only found out when she found the two of them.

What is money, for the people at the bottom, they rarely see even a penny.

Their daily life depends on things and things.

When the merchant comes to harvest, he will also sell the goods, and between the buying and selling, all of them are exchanged.

Each of them was satisfied, and the merchant received the goods, and he was able to go to the city to exchange money for some practical goods that could be exchanged for supplies in the village.

It turns out that money is useless, and it is more tight to make practical and useful things and exchange them out.

If it is ordinary, the farmer can make his own things, and he can't change them.

If it's a strange thing or something of unknown use, you can't change it.

The peasant family is more realistic, and if they are willing to change something, they will change it if they can increase the harvest, and after calculation, they can let them do a little more work.

Moreover, when he sees the appearance, he will not be able to do it himself.

He'd look at what things looked like and go back and make them himself. Such a thing, at most, can sell one or two pieces, there is no way to sell a lot.

Unless it takes a lot of effort to make, they don't think it's cost-effective.

In the Tang Dynasty, gunpowder had not yet become a controlled product.

Fan Jingjing knew that the match she had taken out before, and the woman kept asking how to do it, just to get the way to make it.

In this era, the success of skills is either circulated everywhere or hidden.

Fan Jingjing has no sentiment for the country and the people, at this time, she just wants to return to the life of a rich girl and live well.

Her current life makes her feel that she is standing on a silk thread and may break at any time.

The goods that opened the door were very important, and she decided to choose matches, and really began to study how to make matches, and she realized how troublesome it was to make matches in ancient times.

Fortunately, sulfur itself exists as a medicinal herb and can be purchased at pharmacies.

Phosphorus can also be obtained from urine, animal bones, and struvite stones.

The material of glass powder is quartz sand, and it is not too difficult to obtain the material.

The rarest is probably potassium chlorate.

If you want to get potassium chlorate, you have to make an electrolysis reaction.

If you want to electrolyze the reaction, you have to have electricity.

Fan Jingjing remembered that there were cannons in the Song Dynasty, and potassium chlorate was not used as a raw material for gunpowder in ancient times.

It's a pity that she can't check the hundred X now, otherwise she must find out.

Fortunately, her Maserati for unknown reasons can still use electricity.

She has not yet researched the source of motivation for Maserati.

She checked the tank, but found it missing.
