Da Tang: Three days later, I was frantically collecting supplies

So, Li Kei was determined, step by step, to start conquering the steam engine… Model car.

Of course, if you do it yourself, you can only make a model, and let the blacksmith or even the Ministry of Works do the rest.

It should be easier to let everyone have a general understanding first, and then do it.

Therefore, Li Kei directly took out one of the models, and the piston is still glass and transparent, so that people can understand it at a glance.

Just light a candle below to drive the small steam engine to run quickly.

Then Li Kei found some wood, and then sharpened the pencil, first four wheels, a base, and a body.

Almost according to the structure of the carriage, a small car that can be adapted to a small steam engine was made.

After that, the steam engine is fixed on the top, the drive is connected with a leather band, and then it is placed directly on the flat ground and the candle is lit.

Within three or two minutes, the water inside was boiling, and the steam engine car was running like a wild horse out of control.

Tried it several times in the yard and found that the effect was good.

Sure enough, the modern steam engine model is also quite qualified, although it only costs more than thirty yuan, but this process is indeed an advanced embodiment of the era.

After that, Li Kei made several oxbows again.

It is a herringbone shaped thing, made of wood by Li Ke, and a lot of metal plowshares are set on it.

There is a power to pull in front, and a little weight on the back, and the ploughshare is inserted into the soil

Then as soon as the car left, the ground was ploughed in a large area, and the speed depended on the speed of the car.

Of course, pulling with a cow is more laborious, so the size cannot be too large.

But machines are different, but they can be built.

As long as the load is not so outrageous that it causes a burst, then whatever.

After it was done thoroughly, Li Kei connected the small steam engine with the ploughing tool, and then pressed a brick on the oxbow, bearing the weight, and let the ploughshare insert into the soil.

Then the candle was lit until the water boiled, and the small steam engine spun quickly, took the car and ran away.

Due to the weight and ploughing factor, the run is not so fast.

After all, this is not farmland, it is a yard, and the geology is relatively hard.

Looking at the car running all over the yard, Li Kei suddenly slapped his brain: “Gotta go, I forgot to design the gear!” If this is used, cultivating the land becomes a high-risk occupation. ”

The small steam engine goes out as soon as the fire blows, but the large steam engine must burn firewood and even coal to drive it.

It’s not so simple to put out a fire, and, who knows how fast the car will be, and if you dare to jump out of the car, you will dare to break your leg.

However, hanging up this matter, ten delicate work, moreover, the material must be hard, otherwise it will not be used.

Hey, Li Kei sighed again.

The steelmaking industry is not developed, and it is still difficult to get.

Like a weapon, it is cast, and then through thousands of hammers, the carbon element inside is polished, so that it reaches the standard of high-carbon steel, it can be called a weapon.

Otherwise, it will break when touched, how to fight?

Weapons are good to say, armor is good to say.

But what about other parts?

There is no way to control the carbon content in the molten iron, and it is impossible to cast the required precision parts at one time.

Or, melt weapons with a decent carbon content and cast them into parts?

What a cart before the horse!

It’s a solution, but it took eight lifetimes.

Just as Li Kei was fiddling with the model car of the steam engine, Forber ran in.

“Your Highness, Your Highness, Princess Changle has come to see you!”

Li Ji was shocked and immediately wanted to put away the steam engine.

Who knew that before he caught up with the car, a lively girl ran in upside down.

“Third brother, third brother!”

Li Kei looked her up and down.

Is this product Li Liqian?

This has been Zhenguan for eight years, and he hasn’t married Changsun Chong yet?

Looking at his hairstyle, it is obviously not out of the cabinet, and it has not yet been coiled.

Just such a brush, it is indeed a heavenly color, beautiful and incomprehensible.

Thanks to Forber’s report when he came, otherwise he would be embarrassed if he didn’t know each other.

By the way, I’m not sick, in case I catch up, I say I forgot.

“Changle, why are you here?”

Changle pouted and said with disgust: “Third brother, you don’t want to see me, then I’ll go!” ”

Li Kei smiled awkwardly and said, “Third brother doesn’t mean this, I mean, this is a thousand miles away, why is the father emperor willing to let you out?” ”

Changle said: “Third brother, you gave my father a gift this time, there are a lot of fine soaps, and the father and the emperor also divided me two pieces, it is really fragrant.” ”

“I asked you how you got here, you told me about the crotch shaft, where is this?”

“How else can it come, the medicine mother you sent took it, and my condition improved a lot.” While my father was happy and my mother was happy, I was so soft and hard, so I let me out. ”

Li was stunned.

Is it so coincidental?

It turned out that Empress Changsun happened to be ill, and she sent the medicine again.

It seems that he just gave out the medicine and made a contribution!

Before she became terminally ill, she had two years to live!

However, when he knew that there was a special medicine that could be cured, it seemed that his death hanging method could be realized.

“Third brother, what’s wrong with you?”

Changle looked at Li Kei in a daze, his hand shook in front of him, and he found that he was all distracted.

Li Ke’s mind wandered the world, and when he heard him shouting, he instantly returned to the original god.

“Ah, nothing, I’m just glad I caught up.”

At this time, the steam engine trolley came to the wall and got stuck there, and suddenly sounded.

Changle was surprised: “Third brother, what is that.” ”

Li Kei shifted his gaze and said lightly: “It’s nothing, the little toy designed.” ”

Changle ran over excitedly, reaching out to pick it up.

“Don’t touch it slowly, hot!”

As soon as he finished speaking, Changle reached out and picked up the car.

Fortunately, she noticed the candle flame, pinched the car body in her hand, and did not get it.

But when she saw such a small wooden car, she could actually walk by herself, and she was immediately aroused.

“Third brother, I haven’t seen it for half a year, I didn’t expect you to have so many skills, the toys you make are so powerful, and you can move by yourself.”

Li Kei smiled.

Just don’t hide it from her.

Isn’t it just a steam engine?

With their own resources, it is estimated that it is difficult to build a large working steam engine.

And although this thing has a lot of energy, the structure is too simple, and you can see it at a glance.

In this era, there is no patent protection, so don’t hide it.

The small one made it out by himself, and simply acted as a handshaker and sent it to Li Shimin.

He pays special attention to agriculture, and when he sees the small, he can naturally think of the big one.

Let him arrange for the Ministry of Works to do it.

Li Kei saw that she couldn’t put it down, so he said: “Blow out the flames, this thing is called a steam engine, you just imagine, if you magnify him a hundred times, can you replace the ox pulling the cart?” ”

Changle was stunned for a moment, looked at the steam engine again, and then his pupils shrank sharply.

As if I had discovered something incredible, my jaw dropped completely.
