On the way back.

Gu Qingwan's beautiful face looked at Lu Yuan on the side and said with admiration:

"Lord Shizi, this bike is really amazing.

In this way, every family is equivalent to having a horse, and there is no need to feed it, so it is convenient to go anywhere. ”

Looking at the expression on Gu Qingwan's beautiful face, Lu Yuan grinned proudly:

"What's this, the most powerful thing is a tricycle."

Tricycle?

Gu Qingwan blinked her good-looking eyes and said:

"What is a tricycle?"

Lu Yuan said:

"The front is the same as a bicycle, and the back is a small carriage, which can pull a lot of goods, and a person pulls two or three hundred pounds of goods like playing."

Listening to Lu Yuan's words, Gu Qingwan was a little puzzled.

Because in Gu Qingwan's opinion, this thing doesn't seem to be anything, right?

After all, ox carts can pull goods, and horse-drawn carts can pull goods.

Even if it is a wheelbarrow wooden trolley, loaded with hundreds of catties of rice, then everyone can push it.

Anyway, this thing Lu Yuan said, in Gu Qingwan's opinion, the shock power is definitely not as big as that bicycle.

And Lu Yuan looked at Gu Qingwan's strange appearance, and shook his head with a smile and said:

"Don't you think this tricycle is nothing?

Anyway, ox carts, horse-drawn carts can also be replaced?

No, no.

This tricycle will change the economic model of the entire Lieqian Dynasty~"

Economic model?

So what is it?

Gu Qingwan didn't understand.

However, at the end of this day, Gu Qingwan heard too many new words from Lu Yuan's mouth.

And every time Lu Yuan explained, Gu Qingwan would be shocked.

This time, Gu Qingwan hurriedly sat down and waited for Lu Yuan to explain.

It's so cute.

Lu Yuan looked at Gu Qingwan in front of him, grinned, and said:

"Now the transportation of goods in the Lieqian Dynasty depends entirely on horses or cattle.

Not to mention that these two kinds of animals are raised, and the trouble and cost are still great.

Let's just say how many horses and cows we can have. ”

Gu Qingwan blinked her good-looking eyes and listened carefully.

Lu Yuan continued to say seriously:

"As for the wheelbarrow, it can only be pushed from East Street to West Street for a short distance.

But if it is pushed from the imperial city to Haijin, it will really tire people to death, and the speed is slower than that of ox carts.

But a tricycle can, and the price of a tricycle is only a few taels of silver.

If the cost is low, the speed is comparable to that of a horse-drawn carriage, and the cost of transportation will be reduced.

Then the transportation cost will be reduced, and everyone's life will become richer. ”

Shipping costs?

Affluence?

Gu Qingwan's head was full of big question marks at this time.

Gu Qingwan had never heard of these before.

The books she read at home before were all words and songs, and the words of saints.

I really don't know much about that.

And Lu Yuan continued with a smile:

"There is an old saying that if you want to get rich, you must first build roads.

Why do you want to build roads before you get rich?

Test you. ”

Seeing Lu Yuan ask herself, Gu Qingwan was stunned.

This......

Gu Qingwan really didn't know.

Even, Gu Qingwan didn't know where this ancient saying came from.

Why have you never heard of it yourself?

Gu Qingwan saw Lu Yuan looking at herself with a smile, as if she was teasing herself.

Gu Qingwan couldn't help but be a little coquettish and said:

"Don't sell the prince of the world~~"

At the end of this day, Gu Qingwan was really more and more coquettish to Lu Yuan.

And Lu Yuan said with a smile:

"Listen up.

If you want to get rich, you must first build roads, which speaks of the importance of the circulation of goods.

Without roads, you can't sell the things inside the ravines, and it's hard for the things outside to get in.

Taking our imperial city to Haijin as an example, although there is a wide and large official road between them, there is no large number of means of transportation, which means that there is no road."

Gu Qingwan nodded thoughtfully.

And Lu Yuan continued:

"For example, let's say the pike crab in Haijin City, the pike crab in Haijin City is in our imperial city, and a male crab of four taels costs seventy yuan.

Remember that a four-tael male crab costs seventy yuan!

If it is a New Year's holiday, it will even rise to more than a penny of silver, and the price will directly double.

But do you know how much it costs for the fishermen in Haijin City to sell it when they just come back from the sea?

One pound is only eighteen wen.

Do you calculate how many times the price is different? ”

Gu Qingwan was stunned for a moment, and then immediately did mental arithmetic.

However, Lu Yuan waved his hand and said:

"You don't need to calculate, it doesn't matter how many times the difference is, what matters is why the price is so different?

Because of transportation problems, there is a big difference between the price of the pike crab when it dies and when it is alive.

Transporting from Haijin to the Imperial City requires a quick horse.

Otherwise, if you die of lack of oxygen on the road, the meat of this pike crab will be unpalatable.

Even later, when the crab is cooked, when the crab lid is opened, there is no meat in it, and it is a bubble of seawater.

Therefore, only a few big restaurants in our imperial city will hire horse-drawn carriages to go to Haijin to buy pike crabs and supply them to the rich.

But although this thing is sold so expensive in the imperial city, it has nothing to do with the fishermen by the sea. ”

At this time, Gu Qingwan seemed to understand something, and wanted to open her mouth to say something, but she couldn't bear to interrupt Lu Yuan.

I can only nod my head again and again.

And Lu Yuan continued:

"The reason is that there are not many people who buy it, and it can only be consumed by people in Haijin City.

But what if you have a tricycle in the future?

The transportation cost is reduced, and a large number of pike crabs can be quickly transported to the imperial city.

The price of sea crabs in the imperial city will naturally drop rapidly from seventy yuan to a single one.

When the time comes, ordinary people will be able to afford it

Ordinary people can also enjoy the taste of sea crab.

And as the people of the Imperial City can eat pike crabs, will the pike crabs in Haijin City still cost a pound of 18 Wen?

Naturally, the price will definitely rise sharply, and the fishermen of Haijin will naturally benefit. ”

After Lu Yuan finished speaking, Gu Qingwan now looked at Lu Yuan, and there was nothing but worship in her eyes.

In Gu Qingwan's eyes, this prince is simply not a human being!

It's God!

Shock, except for shock or shock.

Whether it is a bicycle built today or the future development of bicycles, it will change the entire Lieqian Dynasty.

This was too shocking for Gu Qingwan.

As the eldest daughter in the family, her father is the current first assistant Gu Shiqing.

Since she was a child, Gu Qingwan has had all kinds of gentlemen and Confucians to teach.

Among them, there are people who taught the prince before.

But there has never been any gentleman, Da Ru, who can shock Gu Qingwan so much.

These are things that you can't learn at all in books.

In addition, Gu Qingwan was not only shocked by Lu Yuan's knowledge.

And the prince also knows how much is a pound of crabs in Haijin?

How could the prince know about this kind of market matter?

Doesn't it all say that the prince will only look for flowers and willows every day, drink and have fun?

The rumors are all false!

Lu Yuan didn't know what Gu Qingwan was thinking at this time, but he raised his eyebrows slightly and said with some anger:

"What's the matter, I know a lot of things, don't you thank me for telling you this?"

Gu Qingwan was stunned for a moment, and then hurriedly said seriously:

"Thank you, Lord Shizi."

Gu Qingwan just wanted to say something more, but Lu Yuan smiled and said:

"It's all so familiar, what is the name of the prince, more births, and brother in the future, how kind does this sound!"

Gu Qingwan blinked, and then remembered something:

"Shiziye, it seems that we are all born in the twenty-third year of Hongwu, I am March, and Shiziye seems to be coming in May?

If that's the case, then I'll call me the prince in the future, and my brother ......."

Before Gu Qingwan's words were finished, Lu Yuan hurriedly waved his hand and said:

"No, even if you are two months older than me, then you have to call me brother!!

As the saying goes, a teacher for one day and a father for life, I taught you so many things, it's good if I didn't let you call your father!

Do you still want to be my sister?

Just call brother, do you hear! ”

Gu Qingwan looked at Lu Yuan, who had a serious face and was a little tricky, and actually covered his mouth and laughed when he was amused.

And Lu Yuan glared at Gu Qingwan and said:

"What are you laughing at, call me brother in the future, do you hear it!"

And Gu Qingwan pursed her lips slightly, and after looking at Lu Yuan for a few seconds, her voice was extremely soft:

"I know~~Brother~~~"
