I am the cook, but I am Li Er's son-in-law

Magazines have been out for a long time.

There are many contributions.

But... the endless stream of readers, the articles delivered are mostly poems and songs, or some novels.Science fiction is the most.

The above articles on mathematics, physics, and chemistry are still written by a few young girls. Occasionally, Yin Xuan will write an article, and occasionally a few people who were recruited by Yin Xuan to perfect the steam engine will also write an article.

Almost no one sent articles about these disciplines.

A few articles will come up like a needle in a haystack, but the above content is either incomprehensible, or full of mistakes and omissions, and cannot be published in the magazine.

These scholars seem to be quite interested in science, but only interested, just like the food in Tongfu Restaurant.

Let them eat, even pay for it, they will not be stingy, but if you really let them go to the kitchen to cook... then forget it.

Publishing an article can get a job every month?

If it is selected as the essence, can it be ten times a month?

Readers are excited.

Now I finally know the preferences of Zhengyang Gong's recruiters.

It turned out that it was not a question of whether he was pretty or not, but a question of whether he could write articles that satisfied him?It seems that Lord Zhengyang attaches great importance to his theory.

They discussed eagerly.

Some people have dug out the notes that have been carried with them all the time, but it seems that they have not been turned over for a long time.

Some have even begun to think about how to write this article.

Yin Xuan nodded and smiled in satisfaction.

This is what he wants.

With a wave of his hand, he called Jiu'er over and asked her to take this person to join the job.

Several little girls held this document and discussed it, and sent someone to the workshop by the way to let them make this thing.

By the afternoon of the second day, the wheels were made and put on the train.

After the coal was burned, the train whined a few times and began to move slowly. This time it went much smoother. From the end of the alley to the end of the alley, it moved straight forward without any derailment.

This surprised the little girls.

Then I tried it several times, but it was still stable, and there was no derailment once.

Of course... being able to walk in a straight line doesn't mean anything.Although they hadn't even been able to conquer it in a straight line before.

The train is bound to take a curve.

The alley next door was also temporarily covered by Li Lizhi with copper coins, and the track that had been prepared long ago was laid on it, and the train began to test the curve.

The little girls were a little nervous, but... what they were worried about didn't happen. The train passed the curve smoothly and crashed into the sand paved at the end.

Become!

Such thoughts came to their minds.

But the joy was not expressed immediately, it was just that it succeeded for the first time, it was just this one time.When they were experimenting before, they could occasionally make the train go in a straight line, but when they retested, it was difficult to achieve the previous effect.

Several little girls experimented for several days and confirmed the reliability before telling Yin Xuan the news.

Yin Xuan took a look and told Li Yuan to go home and talk to Li Shimin.

The next afternoon, Li Shimin came over.

"I heard from my father that the little surprise you prepared for me is ready?" Li Shimin said with a smile on his face.

Yin Xuan nodded, beckoned, and took Li Shimin out of the house, taking advantage of the fact that there were no guests yet.This made Li Shimin stunned, and a wave of excitement surged up.

Not in restaurants.

Are you going to take yourself to see that mysterious research institute?

Li Shimin followed Yin Xuan around two or three alleys, and the place he arrived at was not the research institute he was expecting, but an ordinary, unremarkable alley.

The only things that interested him were the iron ladders in the alley, and the big black iron pier at the end of the alley.

"This is the surprise you gave me?" Li Shimin frowned slightly as he looked at these unknown things.

Yin Xuan led him to the locomotive, where several little girls were doing the final test. There were coals coming in and out, and their faces and clothes were inevitably stained with black stains.

Seeing that these daughters of his were all involved, Li Shimin immediately realized that this surprise might be bigger than he thought.

"Are you ready?" Yin Xuan asked.

Li Lizhi nodded, shook her head, and saw her father: "Shall we start now?"

"Let's start." Yin Xuan nodded.

The coal on the train had already started to burn. Hearing Yin Xuan's order, the workers inside immediately added coal to the boiler and released the brakes.

Not long after, there was a sound, and the train started to run and gallop forward.

Li Shimin was stunned until the train turned a corner and disappeared, then he came back to his senses: "What was that thing just now, and how did it move it?"

The two people who added coal just now got off the locomotive, and now there is no one on the train, and there are no cattle or horses in front... How did this thing move?

This has completely broken Li Shimin's worldview.

"This is a train, and it moves by burning coal." Li Lizhi pinched her waist and explained, "Dad, do you still remember the steam engine? That thing is installed in the train."

"Using steam power to drive the wheels, and then run."

The words are very simple, but Li Shimin's basic knowledge has not yet been solidified, so he naturally can't understand his daughter's words.

That steam engine...isn't it used to generate electricity and turn waterwheels?How can the car be able to move by itself without the need for horses and oxen?

But whether he understood it or not, the facts had already happened before his eyes.

Li Shimin breathed out: "So this is the surprise we prepared? Good things are good things...but he has to be on this iron ladder to work, right?"

If it can run on flat ground, this thing is filled with dozens of catties of explosives, hits the enemy camp, and then explodes violently, what a big killer.

It's a pity that we still have to run on this rail. We can't lay a layer of rails on the battlefield before fighting, right?

"You're thinking wrong." Yin Xuan waved his hand, showing no mercy to Li Shimin, "How can this thing be used in such a way, you only have a frontal charge in your mind, don't you?"

Li Shimin blushed.

Yin Xuan went on to say: "This thing is used to guarantee logistics. It is much more convenient to build railways than roads, and the restrictions are much smaller."

"From Xiuxiu to Youzhou, the transportation of grain and grass depends on this thing."

"Not only is it faster than carriage and horse transportation, but also think about how much food and grass consumption can be saved?"

Li Shimin tilted his head back, his eyes lit up.

No!
Looking at the locomotive coming back from a lap, the joy that Li Shimin had just ignited disappeared again, and he shook his head: "I'm afraid there is still something wrong."
