Laugh at! Laugh at! Laugh at......

The buried boiler leaked a large amount of white steam from the gap due to pressure relief. It wasn't dangerous, but it was spectacular, just a few breaths, and the surroundings were already foggy.

"Phew!"

Cleaning up the spittle in his mouth, Zhang De frowned slightly, "No." ”

In fact, the sealing method is not the problem, but the smelting quality control is not in place. In terms of sealing, you can use shellac, fig gum and silk mixture. But the metal material itself is a headache.

"Wrought iron, wrought iron, wrought iron...... I'm going to ******—"

Zhang De roared angrily, and a group of apprentices were too frightened to speak.

"Okay, let's go home today."

Then the students, apprentices, and workers all went home with joy.

Leapfrogging development is really not so easy to do.

Technically, the Industrial Revolution is about power sources, energy, and materials. When Lao Zhang was a student, he summarized the technical elements of the first industrial revolution, namely steam engines, coal, and steel.

With the existing means, building a laboratory steam engine is not a problem at all, but its power output is not as good as a mule. Although it makes sense, it is regrettable.

If they can't make people see the profits, the magnates won't jump into it, and they will have to take the huge risk of fighting each other with the emperor

Of course, this is not a technical problem, but a social problem.

Lao Zhang's problem now is that there is no way to mass produce decent wrought iron, let alone others.

Steel has already been produced on a large scale, but this involves the issue of the right of first refusal of materials. The emperor was certainly not interested in the technological revolution. But the pursuit of historical positioning, wash away the small black spots of Xuanwu Gate. He was absolutely interested in establishing the legitimacy of the throne through the prosperity of the past and the present.

No doubt. The products of Shicheng Iron and Steel Plant, the priority is to arm the soldiers of Liaoxi to the teeth, even the dagger used to cut pork chops is made of stainless steel.

Overall, however, the future is bright, and the actual output of the Shicheng Iron and Steel Plant has doubled compared to last year. The inventory of iron ingots has broken the small level of one million catties, the inventory of a Shicheng Iron and Steel Plant. It is enough to beat the annual output of other places in Datang.

Whenever I think of this, Lao Zhang will always sigh with emotion: Lao Tzu is really awesome.

"Forget it, let's think of it as a technical reserve. At this time, I still have to empty my brain and not drill the horns. ”

In fact, Zhang De also knows that if he has been piling up time and materials, it is not a problem at all. As long as the steam engine has a stable output of five horsepower, the drawing area is a magic weapon that will be very helpful in increasing coal production. Of course, this yield is not brushed from the northern regions. It is in places such as Chikushi Island and Huainan Province.

In the past few years, Hebei Province enclosed land, and the open fields basically fell into the hands of large households, and later, although the emperor made a wave, he did not turn his left hand into his right hand. Changed to another wave of big households.

Taking Zhang De himself as an example, nominally speaking, China Resources gave land rewards to employees. It's still very lucrative. But this land. Especially for the reward of arable land, there is a small clause. This clause is the owner of the open field. It is necessary to lease the cultivated land to a well-known large business for ten years.

And then there is a subsidiary clause to this clause, that is, it expires in ten years and has priority.

Basically, the employees are not stupid, very simple arithmetic. The open field has to pay taxes, and then the yield per mu is about 150 catties. Each head is fifty acres, and a household is counted as five heads, that is, two hundred and fifty acres. According to such households, after deducting the tax payment, about 30,000 catties of net income. Converted into the price of grain in Chang'an, it is about 150 yuan.

But this is the price of rice, and the output ratio of milled rice is generally 70% to 80%, which is high-quality rice. Of course, there are more than ninety percent, and this kind of rice cannot be sold in Chang'an.

So one hundred and fifty guan is discounted by eight, and it becomes one hundred and twenty guan. However, the problem comes again, this one hundred and twenty yuan is not something that ordinary farmers can get, and the people who sell rice in Beijing are all aristocratic and wealthy families. To put it simply, the big landlord must be a big grain merchant, since the price of rice from the big landlord is to the point of fighting rice and five cents, the price of grain will only be lower than this.

Therefore, there is a saying that grain is cheap and hurts farmers, and the income of a family with 250 mu of Zhongtian is less than 120 yuan a year. What about the poor peasants who occupy the fields?

Ninety percent of the world's Ueda is in the hands of wealthy families, and it is impossible for ordinary children to get those Ueda with a yield of more than 250 catties per mu or even more than 5 or 600 catties to irrigate the land.

Therefore, the income of the vast majority of ordinary peasants must be meager.

However, in the system of China Resources, as long as it is not a slave laborer, even if it is a ten-year contract laborer, it is also calculated according to the five-person head household, and its annual income in the five years of Zhenguan is more than the annual income of the ordinary family with 200 acres of Zhongtian.

Moreover, after Zhang De improved the roving car, the water-powered loom has also begun to be popularized, but for the time being, it has not been able to achieve the smooth and fine needlework of the peasant weaver girl, which is slightly rough.

But for ordinary people, it is very good to be able to do not cover the body, and the choice of fabric, of course, is the best at a good price.

Therefore, for most farmers in Hebei Province and employees under the China Resources system, leasing the open field to China Resources not only eliminates the need to worry about taxes and pests, but also allows them to earn extra wages in handicraft workshops. According to the grain prices, which are bottoming out more and more after three years of Zhenguan, the peasants who are semi-detached from the cultivated land and the grassroots workers of the China Resources can fully afford it.

The reason why Zhang De wants to do this invisible land annexation is still very simple, to create a market and expand the market.

If you want Xiaobawang learning machine to be born in the Tang Dynasty, there must be a market.

Lao Zhang has taken stock of the situation he is now controlling, and the overseas plantation economy has made a good start, and he has mastered a stable resource plundering land. And the out-of-production population within the empire is expanding at an astonishing rate, and the descendants of those nobles born every year in Chang'an alone are thousands. Even if he makes a pacifier made of fig gum and sells it for 100 yuan, according to one per person a year, this is more than 100,000 yuan. Obviously, there is no way to use only one pacifier, and he can't just stare at these chickens and dogs.

In the next one or two decades, Datang will smoothly develop Jiangnan, and at this time, the resource plundering of the three fleets in the South China Sea will be able to cooperate with Datang's in-depth development of Jiangnan.

Lao Zhang boldly estimated that at this time, there must have been an explosion in the population, and then the handicraft workshops and hydraulic workshops were completely unable to meet the consumption needs of the off-duty population within the empire.

Then, the urgently needed stable power source will come into being. This came into being, not because of the constant failure of his laboratory, not because he was constantly entangled in why some parts of wrought iron were hard, not because of the breakthrough in material processing, not because of the expansion of the coking industry.

Rather, it is the new institutional relationship that has enabled the new grassroots to have some right to speak. Maybe at that time, among Lao Zhang's friends, they would turn over the history books all day long, telling people how awesome the republic of Zhou Gong was.

Of course, Lao Zhang doesn't like the aristocratic republic, but if the little overlord learning machine wants to be born, he must first let the five surnames Qiwang and the royal family die one or two before he can be regarded as a little overlord.

I haven't even tasted the human blood steamed buns of the nobles in the old era, how can I be considered a little overlord?

"Let's put the test boiler first."

Zhang De thought about it, picked up an iron cage, it was a crab pot, stuffed with a few pieces of fish meat and internal organs, and then stared at the cage, Lao Zhang made up his mind, "Catch some big crabs to eat first, and when you are free, then catch big lobsters to eat, continue to be free, go to the sea near the Ghost Country to catch king crabs to eat, if you are still free, go to the deep sea to fish for hairtail fish......"

Then the engineering dog took the people on the boat and went to the Bohai Sea to put crab cages to catch crabs.

Iron cages, through the winch to turn the thin iron chain, slowly out of the water, and then in the cage, are not fat but large blue crabs.

Lao Zhang brought steaming and steaming, and he was very happy to eat, and a greedy pregnant woman swallowed her saliva.

However, Lao Zhang told her earnestly: "Zhiniang, Imperial Doctor Zhen said that if you are pregnant, you should not eat this kind of seafood. Come, watch me eat...... Look at this crab leg, how big, look at this crab meat...... Alas, it's a pity you can't eat it. ”

The pregnant woman didn't hold back, grabbed a piece of crab leg meat and was about to stuff it in her mouth.

But the engineering dog came quietly: "Son, ......"

Syllable!

The crab leg meat fell on the face of the engineering dog.

Suck ......

The engineering dog picked up the crab shell, sucked the soup, and ate the crab leg meat that fell off his face, and the depression of the boiler horsepower was not enough, and it was swept away, which was simply not too refreshing.

"I'm going to go lobster fishing tomorrow—"

The engineering dog holding the crab in his hand roared in the sky. (To be continued.) )
