Du Rufang left, and after Erhu looked at it, he made sure that the other party had gone away, and then spoke.

"Sir, we are currently working on the seal, and I believe that in some time, we can work it out."

Seals, which are prepared for the steam engine.

At the time of the invention of the steam engine, rubber had not yet been discovered and was not used as a seal.

The steam engine uses a sealing ring developed with some plant fibers.

There are also metal mats, which are extremely soft yet durable.

Steam engine, this is what Lu Chensheng introduced to them in the book a long time ago.

With illustrations, the students understood the role of the machine.

The steam pushes the piston, and when the piston moves, it drives the connecting rod to generate power.

For such a thing, the students have been waiting for it for a long time.

Not long ago, they had the craftsmen of the workshop make a simple steam engine out of glass and wood.

Although they can't actually use it, they can see the effect of this thing with their own eyes.

If you zoom in, the power is absolutely amazing!

My husband had already told them a long time ago that once the steam engine was introduced, it would bring about earth-shaking changes.

It's just that there is no sealing ring, and the smelting technology is not very mature, so many difficulties are still being overcome.

The blacksmiths in the workshop also worked extremely hard.

On the one hand, Lu Chensheng explained that he wanted to build a gun barrel, and on the other hand, he was asked by the students to build various equipment that they needed to study, and he gave them some things that they needed to develop and develop.

There are too many things, and it becomes more and more difficult to study.

Lu Chensheng looked at the student in front of him, a little crying and laughing.

Now that I'm a student, I have such a little bit of caution now?

didn't trust Du Rufang, so he didn't explain how the fertilizer was developed.

I still waited for the other party to leave before telling myself about my research progress and plans.

"Well, this thing is very important, you need to develop it sooner."

Lu Chensheng nodded, not caring about the other party's caution just now.

He had told his students that their research projects were so important that they should never tell anyone else if they had to.

It's the kind of people in your own family who need to keep it secret and can't reveal a word.

Therefore, the second tiger was a little wary of Du Rufang just now.

"Good job, have you recorded all kinds of data on the fermentation process of this fertilizer?"

"I've written it down, and it's locked in the secret room of the box inside the research institute."

When Erhu heard this, he immediately replied.

Lu Chensheng nodded with satisfaction, these students are getting older and hotter now, and they are doing things without leakage.

"Very good, the data still needs to be kept secret at the moment, and it may have to be taken out and cooperated with some people in the future."

"Why, sir?"

Erhu was puzzled when he listened, weren't these things all developed by his own people? Why work with them?

"We have too few people, and we have to win over some people in the future, and in order to develop, some things need to be cooperated with outsiders in order to be able to develop rapidly." Romance

Lu Chensheng bowed his head and said.

"What's more, the fertilizer developed by this method will actually be eliminated in a short time, and the progress of your research also represents when these things will be eliminated."

Fertilizer also needs to enter the era of industrial production, and it will not take long for such a soil method to be used at that time.

Erhu was stunned when he heard this, and then nodded.

Indeed, according to what Mr. said, these elements can be extracted from ore and then synthesized into fertilizer.

This kind of soil method really won't take long, and the second tiger was suddenly happy when he thought of this.

"Sir, the student quit first."

He still has a lot of things to do, and he's been away for some time now, so he needs to get back as soon as possible.

Lu Chensheng nodded and waved his hand to let Erhu leave.

The students went back to the research institute, and Lu Chensheng looked at the jars, checked the safety, and then left.

Fertilizer can be used not only for crops, but also for fruit trees and vegetables.

At present, there seems to be a lot of fertilizer in this jar, but when it starts to develop in the future, it is actually far from enough.

Lu Chensheng knew this, so he decided to promote this method in the future, so that more people can make fertilizer.

On the one hand, it meets the demand, and on the other hand, it also increases the demand for work.

In a few days, it will be the Spring Festival.

Heavy snow was falling, piling up everywhere.

With the approach of the Spring Festival, every household began to put up lights, and Spring Festival couplets began to be hung outside the house.

The people who just came to Seongseoul are especially happy.

Because in it, they can be regarded as seeing how good Xinghan City is.

At the same time, I am also glad that I can enter this city thanks to my honest farming.

Wouldn't it be too bad that they wouldn't have a way to come in, or stay outside the city?

It's still possible to eat outside the city, but where can you compare it here?

In Xinghan City, the days of life are called a hope.

In the city, there is a shortage of female doctors, and they have already sent their daughters to study, and some of them have been sent to the embroidery workshop.

The craftsmanship is better, and the embroidered things will be sent to Lu Gongzi's house.

That's an honor for them.

Moreover, even the embroidery month salary is also a lot.

Some of them are still young, and now they can go directly to the school.

These have already been applied, and you can go to the college in the spring of next year.

The house arranged for them in the city had to pay fifty copper coins a month, which seemed to be a lot of money.

But in fact, there are not many jobs that you can find casually in this area.

The various benefits in the city let them know that as long as they stay here, their lives will only get better and better in the future.

In addition to this, they also found that the food in the city was extremely cheap, and there were many delicious dishes.

Although they all need money, as long as they can earn enough money, their lives here are definitely no worse than in other places.

The people who have just entered the city outside are very happy every day, that is, when they go to work, they have a rich smile on their faces, and you can feel how happy they are.
