Goose City.

Outside the satellites.

A newly built factory.

Ma Ritian, Master Huang, Fusu, Zhang San and others are getting together.

And anxiously awaited the results of the experiment.

Because, just today, the craftsmen of Goose City came with news.

said it was under a few days of overtime.

Dozens of craftsmen in Goose City finally perfectly reproduced the steam engine in Zhao Kai's steam engine drawings.

It's not, today.

It was the first experiment with the steam engine.

When Fusu and others came here, they were also looking forward to the results of the test.

Because, after a few days, everyone finally realized how the appearance of the steam engine would be a earth-shaking change for the economic construction of the Great Qin Empire.

"How's that, how's that!"

"Was the experiment successful!?"

Anxiously came out of the test site.

At this time, Zhao Kai was very depressed.

"By the way, what went wrong?!"

"Is the steam engine so difficult!?"

After thinking about it for a long time, Zhao Kai never thought clearly, what was the reason for the failure of the steam engine test? !

"Lao Wang, what do you think is wrong?!"

"Why did we fail this experiment!"

"Didn't you tell me before, do you already know the principle? Also know the working mode of the steam engine!? ”

Wang Feng was one of the first people to follow Zhao Kai.

He is also Zhao Kai's most trusted technical staff at present.

Replica manufacturing of steam engines.

It is Wang Feng who is in charge.

However, at this moment, the steam engine that was painstakingly built, only to find that the thermal efficiency of the steam engine was terrifyingly low, and even the thermal efficiency was close to zero......

This made Wang Feng very helpless.

"County magistrate, it stands to reason that we all know the principles and the technology......"

"By using the inside of the steam engine, the powerful vapor is compressed and discharged, which can push the wheel axle to work......

"But where has this force gone? Could it be that it was swallowed by a rat!? Puzzled, Wang Feng was quite puzzled.

And Zhao Kai was also very helpless.

Because, the emergence of the steam engine, which is the core of Zhao Kai's construction of Goose City this year, mining and textiles in various places, etc., all need steam engines......

"Steam engine"!

It can be said that it affects the whole body by moving.

The most important reason why Zhao Kai asked Yingzheng to abandon the national policy of valuing agriculture and suppressing business, and comprehensively curb land annexation, was because the emergence of the steam engine would greatly liberate and develop the productive forces.

Alienate the people from the primary estate.

Then it can be invested in the construction of the secondary and tertiary industries.

And there was no steam engine.

It's all in vain.

If you want to, Zhao Kai promised Ying Zheng that he would let Daqin achieve the predetermined economic goals! A total of 20 million gold!

Moreover, Zhao Kai asked Yingzheng to promulgate the national policy and go all out to abolish the feudal feud and offend the old aristocracy......

I'm afraid Ying Zheng has been doing this for a long time.

And if Zhao Kai is at that time, he will not be able to make his promise to Yingzheng.

So, no matter how talented Zhao Kai is?

I'm afraid that in the end, his Zhao Kai's fate will be the same as Shang Ying's.

was divided by Yingzheng and five horses.

To appease the anger of the old aristocracy.

So today.

Experiments with steam engines failed.

made Zhao Kai very helpless.

Looking at Wang Feng, he asked anxiously, "Is there a solution!?" ”

"If there is, no matter what the cost, I can do my best to do it!"

Wang Feng thought for a moment.

The structure of the steam engine was carefully studied.

It was found that the steam engine experiment failed.

A large part of this is because of the pistons.

This is because the piston cannot transport the gas successfully......

The steam engine piston that Wang Feng made before was just a kind of smooth wood.

As a result, the wood does not seem to be able to completely compress the gas in the tank.

So Wang Feng thought about it, and then said, "County magistrate, maybe if we can find a more suitable material for the piston and completely compress the gas in the cylinder, then our overall machine can be successfully tested......

"As the county magistrate said before, the structure of the steam engine is not complicated, and the principle is not complicated, but this material is very important, if we can use reasonable materials, the steam engine should work......"

Piston!?

Come to think of it.

Zhao Kai suddenly realized a problem.

It seems that in some previous time travel novels, Zhao Kai once saw that the piston of the steam engine seems to be made of a special material, otherwise, even if the model of the steam engine is made, it is just a model and cannot be used......

I thought about it for a while.

Zhao Kai also remembered that the piston part of the steam engine seemed to be made of rubber, otherwise, other materials would not be able to meet the piston requirements of the steam engine.

"Let the county think about ......"

"It's business as usual!"

"The mining of the mine, the mining of coal, the steelmaking of steelmaking, the piston part of the steam engine, the county magistrate to solve the ......"

"Within half a month, before the Xianyang officials come to inspect my goose city, this county will definitely be able to get the steam engine out......"

Finished.

At this moment, with Fusu and others.

Zhao Kai also left here.

This whole person is not in a good mood.

"Teacher, didn't the teacher say that there was a way, but why did he look sad!?" On the way, rushing to attend the opening ceremony of the Great Qin Empire's Goose City University, Fusu asked.

Here, Zhao Kai shook his head helplessly, "This thing does exist, but you really need to go to the southernmost Jiaozhi and find something called rubber there......"

"Only by using that rubber can we make pistons that meet the standards!"

In fact, Zhao Kai said this to Fusu, and he was only in Mongolia!

Because rubber trees generally grow in tropical climates, they are generally found in Indochina, or near the equator......

Although it is said that in the year of Daqin, there was no ice age in later generations, and the climate of the whole Daqin is still warm, for example, the Loess Plateau today is not the Loess Plateau, but a green forest.

For example, today's Northeast Plain is not as cold and cold as it was later, but just colder than the Central Plains.

So.

Go to a place like Hainan in Jiaozhi.

Rubber may be found.

But it's certainly trouble!

"Cochin!?"

"That's the land of Baiyue, right!?"

"Perhaps, maybe Fusu has a way......

Here, Ben is wondering how to find rubber? Suddenly hearing Fusu's words, Zhao Kai was stunned.

Hurriedly asked, "What do you mean!?" ”

"Could it be that you have a way to help me find the rubber?!"

Fusu shook his head, but said, "No, no, no, that's the case, when Fusu was in Xianyang before, he had a friend named Zhao Tuo, and this Zhao Tuo's father was a merchant who traveled between Baiyue and Zhao and Wei......"

"If it's possible, this Lord Zhao Kui Zhao, he's seen the rubber in the teacher's mouth......"

"If he really saw it, then let Zhao Kui and Lord Zhao bring it back from the south......"

Here, I heard Fusu's words.

Zhao Kai was also stunned.

Yes!

He, Zhao Kai, may not know the situation in the south.

But as Zhao Kui, Lord Zhao may know.

Moreover, is the rumored King of Nanyue Zhao Tuo the son of this Zhao Kui Zhao?!

I didn't expect this to be such a coincidence.

It seems that in historical records, it makes sense that Qin Shi Huang Yingzheng asked Zhao Tuo to conquer Baiyue in the south.

"The teacher can say what kind of thing rubber is, when he came to Xianyang a few days ago, Zhao Tuo was in Xianyang, and now he should be in Nanyang County, if possible, the student asked Zhao Kui and Zhao to go to the south urgently, and he may be able to go back and forth within ten months......

"If there is rubber, this should be able to be brought back!"

See Fusu like this.

Zhao Kai smiled and nodded.

To Fusu this student.

That's finally satisfying.

Because if there is no rubber to make the piston of the steam engine, then all Zhao Kai's plans will fail.

"Good good ......"

"Then it's troublesome!"

"Ma Ritian, bring me the boxes in my room......"

Talking and talking.

The portable horse Ritian brought a black box from the door.

And I saw that in this box, it was filled with nearly 10,000 gold!

"Teacher, what are you!?" Fusu asked suspiciously.

Here, Zhao Kai explained, "Trouble the son, transfer this money to Zhao Kui, Master Zhao......"

"Let's just say that this is just a deposit, if Zhao Kui Zhao can get the rubber back to the county from the south, then the county magistrate is willing to give Zhao Kui Zhao a reward of 100,000 gold......"

Rubber, 100,000 gold.

This is certainly a good thing.

Although it is said that the recent expenses have almost made Zhao Kai's wallet empty.

The year-end dividend of millions of gold sent by the previous Jinzu Impression, Mixue Daqin and other franchise industries is now almost wiped out by Zhao Kai.

But when you think of the advent of the steam engine, it will change this era dramatically.

For Ying Zheng's task requirements, Zhao Kai can also complete it.

And in doing so, become an economic oligarch.

Zhao Kai was also relieved.

……

Meanwhile.

Great Qin Imperial Goose City University.

Early.

The people of Goose City gathered here.

Looking forward to today's opening ceremony.

And those who came today were not only the people of Goose City, but also the merchants and nobles of the Six Kingdoms!

Previously, they had heard about the Great Qin Empire's Goose City University.

They came one after another.

Want to see this Great Qin Empire's Goose City University, what the hell is it?!

It is also claimed that once the school starts, it can suppress Qi Guoji's school palace.

It has become a place where the world gathers.

No, I heard about the ambition of the Great Qin Empire's Goose City University.

Qi Guojixia School Palace Contemporary Great Sacrifice Wine ~ Tian Qun, as well as Tian Qun's little junior brother Zhang Zifang, the son of Korea.

This came early to the gate of the Great Qin Empire's Goose City University.

and held a few mushroom and green vegetable buns bought from the county magistrate's bun shop on the street.

One bite at a time.

Deliciously eaten.

And at the same time, as soon as I saw Zhao Kai's figure, he appeared.

Tian Qun Zhang Zifang's eyes were also immediately attracted to the past.
