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

This group of scholars has been busy for several days.

Then he drove an ox cart, carrying this huge monster, to Tongfu Restaurant.

Pedestrians on the road were curious. They didn't quite know what kind of strange thing this kind of upside-down wheel was, and it was going to be sent to Tongfu Restaurant?
It's what the store needs... Is this the legendary steam engine?
The scholar drove his car and stopped at the door.

The leader took a deep breath and stepped in.

Zhao Yue came up to meet him.

The man shook his head: "I came here to visit the store for something. I'll build a steam engine soon."

Zhao Yue was taken aback for a moment, then looked back at Li Lizhi, and nodded hesitantly: "Then please wait for a while."

The scholar also had no objection, so he agreed.It is a well-known fact that the store owner does not like to be disturbed when cooking, even those who are superior can not break this rule, let alone him.

Turning his head, he walked out.

They would like to continue eating in the restaurant, but... after studying steam engines for so long, they no longer have the money to eat in Tongfu Restaurant.

After Yin Xuan finished cooking and came out, Zhao Yue told him the news.

"If something like this happens again next time." Yin Xuan frowned and waved his hand, "If someone makes any inventions or discoveries, just let me know."

"Don't wait for me to finish cooking."

"Those are the big things."

Zhao Yue nodded in response.

After leaving the restaurant, a group of scholars were waiting outside the door. Yin Xuan leaned over and asked straight to the point: "Have you also made a steam engine?"

Those few scholars were a little excited when they saw Yin Xuan, they nodded repeatedly, but they couldn't even speak.

Yin Xuan waved his hands and smiled: "Give me a hand and carry this thing to the backyard. I'll see how far you have gone."

They nodded and carried the thing in in one go.

Then, I took out the charcoal, added water to the high water tank and the pot, and then waited for the water to boil.

After a while, the water boiled, and the steam rushed from the boiler to the cylinder, pushing the piston up, and then the piston pushed the wheel, and the wheel turned on the switch of the water tank, the water in the water tank sprayed out, cooling the steam, and the wheel turned back...

"Shopkeeper, how about this steam engine we made?" The leading scholar smiled and came over.

They are very satisfied with the machine they built.

"It's pretty good." Yin Xuan glanced at the group of scholars, feeling a little emotional, to be honest... just saw the steam ball, and then it took so little time to make such a machine, it's really amazing up.

"But the problem is still quite big." After boasting, Yin Xuan shook his head and changed the topic.

The faces of the group of people who were about to laugh immediately collapsed.

Yin Xuan looked at them: "It took my wife and the others just over a month to make such a machine."

Their hearts immediately rose to their throats.

Get out their long-term results in a month?

"But this thing was rejected by them. The fundamental reason is that this thing looks beautiful, but it can do very little."

"It's not that you are sorry."

"You guys are really amazing. You can think of separating the cylinder from the boiler. But every time the piston moves, the cylinder needs to be cooled. Not to mention the waste of steam power, it is also a great loss of materials."

The readers nodded.

It's not that they can't understand Yin Xuan's words. In the process of studying this thing, they explored a lot of knowledge that they didn't understand before.

They are also aware of this problem, but... ashamed to say, they have no idea how to solve it.

From what the shopkeeper said, it means that his wives... have already solved this problem?

"Second question, although you have made the wheel, to put it bluntly, the essence is the reciprocating motion of the piston. Would it be better if it were changed to a gear transmission?"

gear drive?
This group of scholars was a little dumbfounded. Most of the words in the second question were difficult for them to understand.

But they couldn't understand these words, but they could understand that Yin Xuan was not satisfied with the steam engine they developed, and he had a much better steam engine than them.

This makes them a little lost.

But before they came, they were already mentally prepared.

It's just that...their thought of staying and working hard for Yin Xuan could not be put into words.

Yin Xuan looked at their faces, saw their thoughts, waved his hand, and said with a smile: "But what I said is all nitpicking."

"Ma'am, they still have my help to repair those things. You just heard about some insignificant things, and you built such a machine. This is a very capable thing."

"The reward promised earlier, after all, you are one step behind."

"However, you and other talented people have always been my favorite. I wonder if a few of you are willing to condescend to do things for me?"

The group of scholars panicked.

Look at what word the store uses, "condescension", what can they do to deserve the word the store uses.

"The store's words are serious. I can't wait for my humble skills. It is my blessing to be favored by the store." The leading scholar quickly bowed and replied, "The store does not dislike it. I will do my best to help the store."

The shopkeeper said this to save face for his group of people.

But people like myself can't really put on a shy face and feel that they are condescending.

Especially my group of people, it's just a waste of effort for so long, the store can not dislike it, and is willing to use them, it is already a matter of gratitude.

really……

The store owner is as rumored, knowing people and making good use of them.

Yin Xuan waved his hand: "It's good to do your best. Regarding the steam engine, I asked my wife to write an article for you during this period of time. You can study it after you go back and read it."

Then, he went to the door, opened the curtain, and called Jiu'er over: "Jiu'er, wait for them to go, these people will be used to study steam engines in the future."

Jiu'er nodded.

Now a few little girls are studying the power generation, but the improvement of the steam engine is also imperative.

Now it just has the tradition of condensation and gears, which can convert steam into power. It is a power machine in the strict sense, but what a few girls built is still a one-way cylinder.

Two-way cylinders, centrifugal governors, pressure gauges, counters, things like that...

When the steam engine came out, it was the beginning of everything.

Just having these seven or eight people is far from enough. Do you want to run a school by yourself?
Yin Xuan rubbed his chin, but didn't make up his mind.

But the urgent matter at the moment is not about the steam engine, but about planting rubber grass.
