With the gods behind her to help, on this day, she actually found oil.

At this time, Feng Yi looked at the black liquid bubbling out in surprise and asked, "National Teacher, what is this?" ”

Nangong Anshan said excitedly: "This is oil, but baby." ”

"What is oil?"

"How to say this, anyway, it is a treasure, which can separate gasoline, kerosene, diesel, paraffin, asphalt, and lubricating oil, which can be used in our daily life in the future. By the way, both bicycles and tricycles can be lubricated. ”

Feng Yi's face was very uncomfortable, he didn't understand a lot.

But he didn't ask much.

Seeing that Feng Yi was still puzzled, Nangong Anshan took a jar and filled a small jar of oil, and then lit the oil with fire.

"You see, this is the simplest use of oil, it can be used for lighting, it can be burned directly, but the smell is not very good."

Feng Yi and the other White Tiger Guards were shocked when they saw this.

This black liquid is so magical, it can be burned directly.

Nangong Anshan conjured a large barrel, filled it with some oil first, and then used the earth shrinking technique to return to Blue Cloud City.

She also introduced oil to Dugu Li and Dugu Huanxu.

She knew that the two of them didn't understand what she was talking about, so she had to burn some of the oil to show them first.

Later, when the oil is refined, she will tell them about the usefulness.

The first day of September

Nangong Anshan came to the new city to sell her bicycle and tricycle.

What she sold this time, she knew that it could sell well even without advertising.

But as soon as she opened, she let the guys in the store take a stroll around town on bicycles and tricycles.

If someone asks on the road, the guys will tell them where they are sold.

In just one stick of incense, there were a lot of guests in Nangong Anshan's car cleaning workshop.

At this time, a guest found a guy and asked, "What kind of car are you?" How can you move forward without horses or oxen? ”

"This is the latest bicycle and tricycle that our owner has developed. The bike is suitable for one person, but it is also possible to ride with a child. You can sit in the back of the tricycle, you can also pull goods, you see, put this up, you can sit people, take this down, you can pull goods. ”

When the guests saw this, they were very surprised.

Both of these are good things.

The customer asked, "How do you sell these two cars?" ”

The guy said: "The bicycle is currently two taels of silver a piece, and the tricycle is currently three taels of silver a piece." ”

This is the price of Nangong Anshanding.

If it is too expensive, many people will definitely think that it is better to travel by horse-drawn carriage without having to exert themselves force.

But if it's too cheap, she always feels like she's worked hard for nothing.

Although at this price now, many people can't afford it.

But if the price is lower, she doesn't know when she will be able to recoup the R&D costs.

The people in the workshop will also have no interest in their work.

When productivity goes up in the future, it's not too late to sell at a lower price.

The guest said, "It's not expensive, so bring me one for each and send it to my house." ”

The guy nodded: "Then please come here to register, after paying, within today, we will definitely send it to you." ”

"Okay."

Seeing this, many other guests also went to register.

Although it is a bit expensive, some people think that the children at home will definitely like it, so they should buy it for their children to play with.

Nangong Anshan looked at the side, then went back to Liuye Village and went to Tomorrow Academy.

Now that the academy is already operating normally, the imperial court and she are trying their best to find smart people to teach here.

She also took out a lot of science books in her system, and she personally taught some people when she had time.

For example, the principles of machinery, how electricity is generated, how to break down oil, what chemistry is, and so on.

In order to make them understand what mechanical, electrical, petroleum and decomposed oil is, she also took samples from the space for them to learn.

Of course, she has not forgotten her younger siblings at home, and she is also teaching them medical skills.

Before Nangong Yao also wanted to study medicine, she was also teaching her.

In this way, Nangong Anshan ran back and forth between the city and Liuye Village every day.

Time passed quickly, and in a blink of an eye, Nangong Anshan was already eighteen years old.

The current Qinglong Country is no longer the Qinglong Country of three years ago.

Over the years, plus the people she saved from the last plague, her merit value has reached 20,000, which can be regarded as a complete merit.

So everything in the system is unlocked.

With all kinds of samples, coupled with the orders of the imperial court, all the smart people from all over the world gathered in Blue Cloud City.

Under the leadership of Nangong Anshan, many modern things have been invented.

For example, kerosene lamps, electricity, telephones, cameras, and even cars.

People have also learned how to extract all kinds of substances they need from oil.

There are also various machines that are also mass-produced, and the traditional hand-held workshops in the past, Nangong Anshan are gradually being eliminated.

Nowadays, weaving cloth is not entirely manual, and with various machines, all kinds of goods can be mass-produced and the price of goods is lower.

There are many other modern things, all of which are also produced.

Bicycles and tricycles invented three years ago, because of the production of machines, can be mass-produced, and the price has dropped again and again, and now ordinary people in Blue Cloud City can afford them.

Compared with three years ago, the Qinglong Kingdom at this time can be said to have undergone earth-shaking changes.

And in Nangong Anshan's house, Nangong Sheng and Nangong Xiu, Nangong Jin, Nangong Jun and Nangong Jie have also married and had children, and now the children can walk.

Nangong Cheng and Nangong Mo, as well as Nangong Yao, did not live up to Nangong Anshan's expectations, and now the medical skills are not superb, but they have reached a level where they can take charge of themselves.

On this morning, many courtiers arrived at the palace in cars.

Cars are now considered a luxury, and it is not easy for ordinary people, except for the wealthy, to have them.

Although the automobile was invented over the years, the rules of the palace remained the same, and the courtiers had to walk to the court.

There are also many places in Duguli's palace that have been renovated, such as those connected to the wires.

Because of the invention of the telephone, now Duguli wants to get the news faster than before.

I often go to the morning court, and I get news thousands of miles away, and then quickly change the topic.

Dugu Li looked at the courtiers and said in a loud voice: "Everyone, last night I received news that the southeast coast once again repelled pirates. Those pirates were able to land only by hijacking the ships of our country's merchants. Therefore, some coastal officials suggested that the coastline should be blocked, and the country should not be opened again, and no people should be allowed to go out to do business, nor should they be allowed to enter. I don't know what you guys think about this? ”
