Three thousand taels of silver.

Even Wan San's face next to him changed color, and he began to feel annoyed in his heart.

It's an eye-catcher.

The eldest prince is young and polite, why did he faint and believe that the eldest prince is a tiger who does not eat people.

Three thousand taels of silver, although it will not bankrupt the Zhang Dong family, but it will also hurt the muscles and bones.

After all, what people come up with is profit, real money.

You must keep a low profile.

The old craftsman secretly admonished himself.

The rabbit died and the fox was sad.

In the past, he scolded Zhang Dongjia at home for not being a good thing, but now facing Xungui together, Wan San and Zhang Dehui sat together.

Zhu Gaochi just doesn't know how to do business, it's not that he can't look at people's faces, seeing everyone's expressions, knowing that they misunderstood, he opened his mouth to explain: "Zhang Dongjia, look."

"The machine only needs to boil water to turn, and the coal used to boil water only needs to be made from local materials, and it doesn't cost much, but it can run all the time, day after day, year after year."

"You have to calculate the general ledger, or it won't take long to return to the capital, and the days to come will be all profits, so you will make money."

New products are never made overnight.

For example, the invention of the automobile is also the result of many years of public opinion that cars are easy to hit and kill people, and cars should be banned.

Birds die for food and for money.

Three thousand taels of silver can't cost Zhang Dehui's life, but he is distressed, and he wants to give it a try.

The eldest prince is not like a ruthless person.

Summoning up his courage, Zhang Dehui tried to open his mouth to negotiate, "The machine is very good, but the student's mine doesn't need ten units, and the official coal next door should be fine." ”

Woe to the east.

Zhu Gaochi disagreed.

Although the imperial court has opened official mines, there are ambassadors who cannot enter the stream, and there are many regulations on private mines for the people, but the regulations are regulations, and the reality is reality.

Official mines are not as good as private mines.

There is only one official mine in Xishan District, and there are more than 10 private mines.

The demand for all kinds of ores has made the government turn a blind eye and promote the development of the private mining industry.

Dealing with people and mines only needs to negotiate profits.

And when cooperating with the government and mines, there are more things to consider, but it is easy to get into trouble, and good things become bad things.

Whether it is in terms of customer size or convenience, Zhu Gaochi does not plan to cooperate with the government and mines first.

"Ten units is a good deal." Zhu Gaochi retorted.

Before the steam engine was widely available, the Cornwall mines in southwest England purchased only one Newcommen engine.

In less than thirty years, there were more than 100 steam engines in the Cornwall mines.

The scale of Zhang Dehui's mine is the largest in Xishan District, Peking Province.

Beiping Mansion is not Beiping City.

Putting forward the number of ten steam engines is not Zhu Gaochi's mouth.

"Ten steam engines, enough to empty groundwater, is equivalent to expanding your mine by at least ten, if not a hundred."

The eldest prince is right.

Wansan woke up.

People think that the eldest prince is right, because the eldest prince settles the accounts clearly.

The people present were either craftsmen or mine heads, or businessmen.

Everyone has an account in their hearts.

The eldest prince didn't talk nonsense.

It is rare to have a reasonable nobleman.

Everyone's eyes turned to Zhang Dehui, and the pressure was passed on to him.

Zhang Dehui smiled bitterly and looked at everyone helplessly: "The coal produced by the mine has a place to go, and the production capacity has increased ten times out of thin air, where to find so many buyers." ”

Oh, yes.

Zhang Dongjia is right.

Not to mention that the people use more firewood, even in the iron smelting station, charcoal is also used, and coal is not good.

The crowd came to their senses.

Zhu Gaochi was speechless.

There are not many coal mines in Daming, there are more coal mines in the north, and there are various mines on the grassland, which are also abundant.

However, because of the groundwater, mines are mostly located in areas where minerals are exposed to the surface or can be easily extracted.

And the transportation cost is high, and it is difficult to transport over long distances.

Under a variety of constraints.

So the capacity of coal mines is not high.

The amount of coal used represents the degree of industrial development in a country during the industrial age.

"Zhang Dongjia's coal mine production is high, and the price can be cheaper than other people's, how can I worry that no one will buy it."

Seeing that the eldest prince was stumped, Wan San interjected to help.

In the past, even if Wansan had a big face and dared to sabotage his own affairs, Zhang Dehui would have to show him his face.

Now there are nobles by his side, but he can't be majestic.

So he politely explained to people.

"As the saying goes, cutting off people's wealth is like killing their parents, to put it mildly, the thirteen mine owners in the Xishan mining area, who has not had a conflict, but there are some things that cannot be done, which will cause public anger."

The words are not rough.

Zhang Dehui's reason is convincing.

Zhu Gaochi suddenly understood a truth.

Why steam engines work well, and it took thirty years for the Cornwall mines to increase the number of steam engines to thirty.

Because of the market.

The purchase of steam engines increases with the size of the market.

Thirty years.

All walks of life in the UK have eliminated the original fuel and used coal on a large scale.

With the role of the steam engine, the effective usable area of the mine has increased exponentially, and the coal mining rate has increased exponentially.

So coal is getting cheaper and cheaper, and it is gradually becoming the main fuel used by people.

Anything that goes against the principles of nature will not succeed.

If you want to promote the steam engine in the shortest time, the price of the steam engine is only the easiest problem, and the real problem is the market demand.

……

"Click."

The sound of the machine attracted everyone's attention.

The shaking arms slowly stopped.

The machine doesn't move.

Everyone looked at Zhu Gaochi.

Zhu Gaochi's face was flushed, and he couldn't wait to find a crack in the ground to drill down, so he didn't slap people in the face like this.

"Hey, hey."

"Accident, pure accident."

Whether it was an accident or not, it all depended on the eldest son's mouth, and Zhang Dehui cried with a sad face.

I have wronged the eldest son.

He can obviously grab money, and he still works so hard.

We can't live without that realization.

"The eldest son, we can't compare with the Hui merchants and Huai merchants, and even less than the salt merchants, the mine is a small business, and the profits are not rich."

first called a bitter call, and finally gritted his teeth and said: "This machine students bought it, the quantity is discounted, the price remains the same, the students buy five units, what do you think?" ”

Zhu Gaochi's face turned cold.

"Bastard, what nonsense."

Several guards stepped forward as they cursed and drew their swords.

"The small one said the wrong thing, damn it, damn it, the small one bought twenty units." Zhang Dehui immediately changed his words, and his voice was so frightened that he was about to cry.

He also has thugs in his hands.

Outlaws have also been raised.

However, people are regular soldiers, killing themselves is like slaughtering chickens, where do you dare to resist.

Zhu Gaochi was dissatisfied: "What are you doing, go down with us." ”

With his words, several guards put away their swords and retreated, their movements sharp, and they looked like heroes from the battlefield.

The atmosphere of slaughter did not dissipate, and people did not dare to speak.

It's hard to do business.

No wonder his parents in his previous life warned him, saying that he was not a business material, and only let himself find a factory to make screws.
