Traveling through the famine, there is space for the daughter-in-law of the farm

The steam engine was once the most important prime mover in the world, because its appearance caused the Industrial Revolution in the 18th century.

The original steam engine had a simple structure and a single function. It could only provide power for the operation of machinery. There was no relative friction inside and no lubricating oil was needed, only water.

With Yan's current iron-making technology and her tips, it would not be difficult to build a steam engine.

The steam engine propelled the ship and transformed the ship's power from human and natural force into mechanical force, making it easier to build larger ships and transport more cargo.

In addition, she can also improve the fishing structure of the ship based on the detailed analysis of the space intelligent computer, improve the control of the route and weather, and make the ship travel safer and more stable.

Zhao Yunning used the space intelligent computer to calculate again. If the existing sailing ship was directly improved into a steam ship, and a single trip to sea could catch at least 20,000 kilograms of weight.

Twenty thousand kilograms!

Five ships weighed 100,000 kilograms. Even if they only came back once every three days, on average, it would be enough for food supplies.

The light in Zhao Yunning's eyes is getting brighter and brighter. Being able to save people is certainly a joyful thing.

She immediately said to Butler Qian: "Bring a pen and paper!"

Zhao Yunning quickly finished writing a letter and handed it to Zheng Duo, "Please give this letter to Haifu Yin personally and ask him to arrange it as soon as possible."

Zheng Duo accepted the order, and Zhang Mayi immediately asked impatiently: "Princess, what about me, don't I need to ask them to donate food?"

Zhao Yunning shook his head, "If necessary, I will notify you when the people at the city gate disperse and we enter the city."

The princess's arrangement was naturally justified by the princess's reasons, so Zhang Mayi didn't ask any more questions.

Zhao Yunning remembered that Li Quan was a carpenter and Li He was a blacksmith. Together, they were able to make a model of a steamship.

Zhao Yunning called them over, gave each of them a drawing, and asked them, "Can you understand it?"

As a qualified carpenter and blacksmith, reading and drawing drawings is a necessary skill, but they have never seen such precise and detailed drawings.

At first glance, it was as if it were vividly displayed in front of them.

Apart from the professional language above, they don't quite understand it. They can definitely make it by following the detailed step-by-step instructions on the drawing.

Brothers Li He and Li Sheng nodded, but they didn't know why Zhao Yunning asked them to make such a thing.

Zhao Yunning asked, "Restore it intact according to the drawings. I will have people prepare all the materials for you. How long do you estimate it will take?"

The steamship model Zhao Yunning asked them to make was only as big as a watermelon.

Li He said, "If the princess is in a hurry, I can get out of the ship within two hours."

Li Sheng said: "Forging molten iron takes a little longer, but tomorrow morning, even small ones can be completed in a hurry."

Zhao Yunning also used the smart computer in the space to calculate the time it would take to build a large steamship using the time they said. Adding extra manpower and material resources to the estimated time, he could build a ship that could catch 200,000 tons at a time.

For a steamship, it will take at least four months.

Four months is not too long, but the rewards are huge. Even after the disaster passes, it can promote the significant development of the local fishery.

It just so happens that the labor force can be dispersed among the shipbuilders to avoid a large number of idle workers in winter, causing various problems.

Zhao Yunning said to them, "Okay, then you will have to work hard tonight."

Although Li He Li Sheng was curious, Zhao Yunning realized that it was a matter of confidentiality. He hurriedly promised to quit and followed the money housekeeper to receive the materials.

Soon, the next morning, Li He Sheng brought the things made by the two.

Zhao Yunning picked up the boat to look at it, and could not surprise Li He's amazing crafts. The drawings did not require him to be very fine, but he did it like a artwork.

Zhao Yunning praised: "It is very beautiful and delicate."

Li He hurriedly said: "The drawings of the county's main paintings are lifelike, and the small one can be handy." And praise, "The county owner is the most unique ship that has seen!"

Zhao Yunning smiled, of course, the most unique ship, this is the steam sailing boat in the eighteenth century.

Li Sheng saw Zhao Yunning picked up a small steam engine and was very embarrassed.

He restored the finished product according to the drawings, and he still couldn't guess what it had to do with this thing.

I did n’t know, Zhao Yunning added some water to the steam engine, and a dwarf candle was placed underneath. The magical scene happened.

"噗 噗 制作" The iron ware he made turned around, and the speed was very fast.

The handle was raised by Zhao Yunning, and the speed was slower.

Li Shengyan was surprised. The original role of the handle was the speed of regulation.

If it wasn't for himself, Zhao Yunning thought that the small steam engine holding in her hand was the modern model she bought.

Zhao Yunning obviously showed a happier smile than just now. "Your craftsmanship really makes me amazing, and I am very satisfied." And said, "If the steam ship can succeed, you will be the most important ship engineer of our Yan Kingdom in the future."

Steam ship? Ship engineer?

Zhao Yunning said what they didn't understand, but they didn't prevent them from staring at Zhao Yunning's next every move.

Zhao Yunning put the combined drawings of the steam ship in his mind, and carefully fixed the steam engine on the reserved position.

Lihe Li Sheng suddenly realized that the hull and steam engine were one.

Zhao Yunning put the integrated steam ship into the large water basin prepared earlier, and lit the candle again.

A more amazing scene happened, and the steam turned into the motivation to promote the movement of the ship, driving in the basin.

Without any wind, manpower, just ordered a candle alone, and moved it!

Lihe Li Sheng was shocked, and suddenly a huge steam ship flashed on the sea on the sea, and the prestige was driving.

The county master is too smart!

Even if they only recognize a few big characters, they also understand that this structure can make Yan Guo's navigation technology far ahead.

Zhao Yunning had already expected, and still pretended to be surprised. "It turns out that the rabbits I saw in the Tibetan Pavilion are really useful!" Try to try the rudder, and the rotation is still sensitive.

To them, "Is there any way to make the rudder and steam engines connect more harmoniously."

Li He and Li Sheng hurried forward to check it carefully. After a while, he discussed the plan, "Welding gears, wooden bar tenon, can be connected more harmoniously."

Zhao Yunning nodded, "Then you go back to rest first, and then continue to study. When you study it, you need to take people to improve our current sailboats to increase the amount of fishing, so that the people can fill their stomachs."

The county owner's great achievements, maybe even them can be named.

Li He and Li Sheng glanced at each other, and his eyes were exciting. "The county master is good, and the small one will do his best!"
