"That's a lot of work... That's where it is! ”

Yun Shu couldn't cry or laugh, when she used to work in the media, she often didn't sleep all night in order to cut a film.

"Besides, didn't you give me five little girls!"

Yun Shu glanced out of the door, and the five little maids were busy adding water to people, and their hands and feet were nimble.

"I've already worked out a training plan for them, and it only takes one year, and I'm guaranteed to make a big difference for them!"

Yun Shu smiled confidently, the age of fourteen or fifteen years old is the time when their brains are bright, as long as they are willing to study hard, they will naturally be able to make progress soon.

Si Mo picked up the teacup and took a sip, "That's their blessing..."

It is far from enough for these five girls to be selected according to Si Mo's standards, but this is the situation here.

These five rings are still the most handy among the dozens of rings in the village.

"Mother, these... What is the meaning? ”

Rice reached out and pulled Yunshu's sleeve, and carefully placed the book that had been holding him tightly in his arms just now on the table.

Although he has now learned a lot of characters from Mr. Zhou, there is still a big difference between simplified and traditional characters.

Rice has even read a lot of stumbling and stumbling, although he can't understand many places at present, that doesn't prevent him from remembering them all first.

"You've seen it all?"

Yun Shu glanced at the page number of this page, twenty-three pages...

He's seen so much in one night!

The book is in full-color edition, with more pictures than text, and is preceded by some simple mechanical sections.

There will be a few lines of simple text on each picture, presumably some simple mechanical principles.

The system is really entertaining and practical.

This is a good thing that Yun Shu found by chance on the system mall, and it cost her 20,000 points.

Yun Shu found out that those basic materials in the system mall are very cheap, which can be called the price of cabbage.

But the books, the drawings, the technology... But it is the most expensive, and it is expensive!

"You can understand all of this?"

Yun Shu looked at the rice in surprise.

The book is typeset in order from easy to difficult, and the mechanics in the front may be simple, but the further back it goes, the more difficult it becomes.

Page 23 already talks about the steam engine...

"Almost..."

Rice's little face turned red for a moment, "Most of them can understand..."

"I'll be a good girl!"

Yun Shu was really shocked now, isn't her cub Mo a genius?

"It's just that these things can't be understood..."

Rice said embarrassedly, pointing to the English letters.

"These are proper nouns, and this one refers to the steam engine... That's it..."

Yun Shu's finger pointed to the section of the steam engine, "The working principle of the steam engine is how to convert thermal energy into mechanical energy..."

"The water in the boiler chamber is heated and vaporized into water vapor, which is used to push the piston to move with huge air pressure and generate mechanical energy..."

"This device is similar to the one in a plug pump, which controls the steam to push the piston back and forth..."

"Then the reciprocating power of the piston is converted into motion through the crank connecting rod mechanism, so as to promote the operation of various equipment..."

Rice doesn't seem to understand it, if he can understand the machinery in front of him, then it's a little difficult to understand when it comes to the steam engine.

The first chapter briefly introduces some ancient mechanical principles, as well as some of the various things that are made with machinery.

It is mainly some machinery such as gears and levers, and at the end it also briefly involves the principles of some pistons and cylinders.

In fact, the principle of the steam engine is not very difficult, the difficulty is that they have not seen the real thing, it is all based on their imagination, which is a little difficult.

Rice carefully wrote down Yun Shu said that when Mr. involved said that when he didn't understand the meaning, he mainly remembered it and would understand it one day.

"What is this? Don't use a horse-drawn cart? ”

Rice's words attracted Xiaomi's attention, and she put down the teacup in her hand and leaned her little head to look at it.

"Mother, can the car run without a horse?"

Millet asked with a milky voice, pointing at the steam-powered train.

"This is a train, and the front part of the locomotive is equipped with a steam engine... The steam engine moves the train around..."

It wasn't clear on the picture alone, Yun Shu's heart moved, and he exchanged for a pocket locomotive the size of a stationery box in the system mall.

This locomotive is exactly like the one in the picture, except that the locomotive also has a circular track.

The locomotive is equipped with a miniature steam engine, which can be moved when it is lit by adding charcoal, just like a real train.

As soon as Yun Shu took out the locomotive from the pocket he was carrying, the eyes of the two cubs were instantly attracted.

"This locomotive has a steam engine in it, and we just have to fill it with charcoal and light a fire to make it move!"

"Really?"

Xiaomi's mouth opened wide, looking at Yun Shu expectantly.

"Nature is true!"

The system is produced, it must be a high-quality product!

Besides, this little locomotive cost her 30,000 points, and she can't run, but she has to return it!

Yun Shu started to fill the charcoal without being very skillful, ignited the fire, and when the water boiled, he turned on the brake button...

Whining...

A puff of white smoke erupted from the locomotive's chimney, and as the machine turned, the locomotive began to glide slowly along the tracks.

"It's really moving..."

Xiaomi was excited, and Rice looked at the little locomotive in front of him intently.

"Of course! The power of the train is very strong, and after the railway is repaired, the train can carry most of the transportation..."

Yun Shu saw that the little guy was very interested in the little train, so he couldn't help but say a little more.

Whether they understand it or not, plant a seed in their brains now, and sooner or later it will take root and sprout.

"This... When can it be made? ”

Si Mo stood up with a swish, looking at Yun Shu in horror.

Just because the two cubs don't know what this train means doesn't mean he doesn't know what this train means.

All it takes is a little charcoal to make something this big move...

Horse-drawn carts, ox-carts, and manpower could transport supplies, but they were also expensive.

Horses and cattle need to eat forage, they will get sick, they need to be carefully cared for, and they need to rest in special weather...

But this kind of machinery is not needed at all, just some firewood...

It's a miracle!

His movements were a little bigger, causing Yun Shu and the two cubs to suddenly set their eyes on him.

Yun Shu thought about it seriously, "If you can find iron ore and coal mines... Not a big problem! ”

"Iron ore can be used to make steel, and steel can be used for construction and can also be used to make steam engines."

"Coal mines are also a must... Oh... Coal is a black stone, and when burned, black smoke comes out..."

"Coal burns at a higher temperature than charcoal, and it is very useful in many places, such as smelting steel..."

"Steam engines are also generally powered by coal..."

"If I'm not mistaken, you can find coal and iron ore in or near Qing County..."

The author of the novel is a person from her world, and the world she writes about should also be based on her world.

If this inference is correct, the probability of having coal and iron mines in Qing County is as high as 80%...
