Daming: Old Zhu, we agreed not to rush!

Chapter 108 Su Jing's Manual Class
early morning.

As always, I ate breakfast, but because there was one more person, there was one more breakfast.

But Su Jing didn't need to worry about these, Zhu Biao completely took over the responsibility of taking care of his younger brother Zhu Wei.

As the saying goes, an older brother is like a father, and Zhu Biao has done a good job in this regard.

Of course, Zhu Wei is not as difficult to manage as a nine-year-old child in the general sense, and it is not an exaggeration to describe it as a young adult.

It's just that Su Jing is still a little uncomfortable with suddenly having a nine-year-old child beside her.

He still remembered the conversation last night.

It can only be said that there is no shortage of talented teenagers in every era, no, they should be called precocious children.

As for whether he is a genius or not, that depends on the future.

"Master Su, are you teaching my younger brother today?"

Zhu Biao was the first to ask.

Since my younger brother has a strong desire to learn from Su Jing first, and it's not just a whim, he, as an older brother, naturally needs to support him.

Su Jing glanced at Zhu Biao, knowing the meaning of the words, but he didn't reply and continued to eat breakfast.

On the contrary, Zhu Wei was much calmer, eating breakfast silently.

At this dinner table, one is his teacher and the other is his elder brother.

They are all elders, people who need to be respected, and they can't talk casually.

Zhu Biao saw that Su Jing didn't speak, so he didn't continue, and the breakfast ended in silence.

"Niu Yi, you have to continue making telescopes today."

Su Jing asked Zhu Biao suddenly.

Zhu Biao was taken aback for a moment, then nodded and said, "Yes, Master Su."

There was joy on his face, but not for himself, but for his younger brother Zhu Wei.

This Su Jing asked himself if he would continue to make telescopes at home, wouldn't that mean that he had time to teach Zhu Xi.

"Stop for a while, I'll teach you to do another thing."

Su Jing's words made Zhu Biao stunned, why it was a little different from what he thought.

This.
Zhu Biao was at a loss for a while.

"Why, don't you want to learn?"

Su Jing's voice sounded faintly.

"No, Master Su, the students are willing to learn."

Zhu Biao replied immediately.

Zhu Biao has no reason to refuse Su Jing's proposed teaching.

"Then what should my brother do now?"

Zhu Biao asked Su Jing again.

Su Jing turned his head to look at Zhu Wei and said: "Whatever you want, I don't care."

"Thank you, Master Su, the student understands."

Zhu Biao immediately thanked Su Jing, and urged Zhu Su who was beside him: "Fifth brother, please thank Master Su."

"Thank you, Master Su."

Zhu Wei reacted quickly, and immediately imitated Zhu Biao's appearance and thanked Su Jing.

Both of them understood the meaning of Su Jing's words, and Zhu Wei could listen in.

Although he didn't know what Su Jing would teach Zhu Biao, Zhu Biao was still very excited.

The two followed Su Jing to the courtyard, stood respectfully, and waited for Su Jing's teaching.

Su Jing directly took out more than a dozen small spherical glass beads the size of eyeballs, put them in front of the two of them and said: "Your task today is to polish a small bead by one person. The smaller the better, the rounder the better. There are flaws, and there can be no cracks or impurities inside, at least get me three."

Ok?
Isn't it teaching?
Why is it suddenly necessary to polish the glass?

Zhu Biao and Zhu Wei looked at each other in blank dismay, somewhat confused about Su Jing's operation.

But the two obediently picked up the tools and started the work of polishing.

Zhu Biao obeyed Su Jing's words unconditionally.

As for Zhu Wei, his elder brother obediently did it, so what right did he have not to do it.

That's how the two started grinding.

Each person has a small turntable, fix the glass in the central position, then turn the turntable, first use coarse sandpaper to polish off the corners little by little, and then change to fine sandpaper.

This is a prop specially made by Su Jing to polish the lens, somewhat similar to making pottery.

By rotating, to ensure consistent grinding.

Otherwise, every direction is judged by the naked eye. I don’t know how to polish it in the Year of the Monkey.

It is not a particularly difficult thing to use to polish beads now.

Moreover, the raw materials Su Jing gave were originally glass beads, but they were a little bigger.

All it takes is patience.

Coincidentally, both Zhu Biao and Zhu Huan have this point.

After breakfast, the two worked until noon.

When Su Jing reappeared, he found that several polished glass beads had already been placed on the plate, only the size of the head of chopsticks.

The two were still polishing, while Su Jing picked up one and carefully observed it through the light.

The surface is quite round, and there are no major problems inside, basically guaranteeing that there are no flaws.

After looking at all of them, Su Jing nodded slightly.

Zhu Biao and Zhu Huan did a pretty good job. Although I don't know how the effect of these glass beads is, at least we can try it.

However, Su Jing didn't have too much hope. After all, it was just a hand-polished thing, and there must be a gap between it and a machine lathe.

If it really doesn't work, then he can only spend money to build a wooden lathe, and then teach himself how to do it, and try a little bit.

"Okay, let's stop, after dinner, the teaching will officially start in the afternoon."

Su Jing said to the two of them.

"Yes, Master Su."

"Yes, Master Su."

Zhu Biao and Zhu Wei both nodded, and the three quickly finished their lunch.

As soon as they got home, Zhu Biao and Zhu Xi began to look forward to it.

What will Su Jing teach them?

Su Jing didn't take any lunch break to hang on to the temperament of the two, and took out the things she had prepared in the morning.

A cylinder made of hard paper, bronze mirrors, silk cloth, thin wood chips and other messy things.

I saw that Su Jing cut a thin piece of wood to fit the cylinder cover, poked a small hole in the middle, and then covered it with a layer of silk cloth, along the small hole in the middle of the cover just now, let the silk cloth also poke in the same position break.

After that, Su Jing took out a glass bead polished by Zhu Biao and Zhu Wei, and stuffed it into the small hole.

With the flexibility of the silk cloth, it was firmly stuck in the hole.

The lens barrel began to be stuffed with four lenses that had been prepared earlier, and placed according to certain specifications.

After being busy for a while, Su Jing finally stopped.

"Niu Yi, go and get a fresh leaf."

Su Jing said to Zhu Biao.

"Yes, Master Su."

Zhu Biao nodded, and immediately fetched a leaf. Although there are not so many fresh and tender leaves this season, they can still be found.

Su Jing took the leaves, put them in the middle of the cylinder, put them on the stage, and then transferred these things into the house, Zhu Biao and Zhu Huan followed them in, the door was closed, the windows were also closed, and the house was instantly emptied. It got dark.

"Niu Yi, go to the window, open it a little less, use the bronze mirror to reflect the sunlight, and come to this position."

Su Jing issued an order to Zhu Biao again, pointing at the small gap in Yuantong.

"Okay, Master Su."

Zhu Biao immediately followed Su Jing's request.

A beam of sunlight was reflected to the position of the cylinder in this way.

Su Jing put her eyes on the small glass bead, and then carefully moved the log to adjust the focus.

After some patient attempts, a clearer image finally appeared in Su Jing's field of vision.

"Fortunately, it works."

Su Jing murmured to herself, and felt a little more relaxed.

This condition can only be said to be crude.

Although what I saw was not very clear and the multiples were not that great, it was still okay.

At least in front of this new student, Zhu Wei, he should be able to pretend.

I can't grow it, but I can do it somewhere else!

At this moment, in Su Jing's field of vision, he could see the veins and lines of the leaves, and some extremely subtle things could be seen at a glance.

That's right, this is Su Jing's self-made microscope.

This was taught to Su Jing by a certain child when he was playing with the child during a visit to a subsidized orphanage in his previous life.

But props are much more advanced than that.

I bought glass beads, small plastic medicine bottles for cylinders, small flashlights for lighting, and scotch tape for the stage.

It can only be said that Su Jing felt that such a simple homemade microscope was really simple at the time, but now he only feels that the one at that time was actually very advanced.

Although the materials are things that can be seen everywhere in life, but in this Ming Dynasty, it is really difficult for you to find substitutes.

Whether it's glass beads, plastic medicine bottles, or flashlights, they are all things that can only be made by modern industry.

These in themselves represent the development level of science and technology and the development level of industry.

Su Jing now has a little more understanding of the three major industries and productivity.

Of course, Su Jing is quite proud now.

Because in the Ming Dynasty, when the materials in the orphanage were not even available, he even made a microscope himself!

Although the microscope does not seem to be very worthy of the name, it is at least usable.

"Niu Yi, don't move."

Su Jing asked Zhu Biao, then looked at Zhu Biao and said, "Niu Su, come over and have a look, just put your eyes on it."

"Yes, Master Su."

Zhu Wei immediately came to this self-made microscope, followed Su Jing's example, and put his eyes on it.

With just one glance, he was attracted.

"this is"

Looking at the scene in front of him, Zhu Wei was a little speechless.

On weekdays, he will carefully observe the shape of the leaves, including the texture on the surface and various details.

So at this glance, he saw what was in front of him.

Of course, it also has something to do with the average magnification of Su Jing's self-made microscope, which didn't magnify too much.

Also the pattern is somewhat distorted and offset due to the use of polished glass beads.

But this still made Zhu Wei feel extremely shocked!
The telescope was introduced to him by his elder brother Zhu Biao last night, an artifact that can see miles away.

At that time, he was incomparably surprised and shocked.

Now, another artifact that can be seen as small appeared in front of him.

There are no words to describe Zhu Wei's heart.

"Be careful, it's not easy for me to debug."

Su Jing reminded, then came to the window, and said to Zhu Biao: "Give me the mirror, you can go and see it too."

"Yes, Master Su."

Zhu Biao nodded, carefully handed the mirror to Su Jing, and then slowly came to the microscope.

Zhu Huan stepped back, and both of them were quite careful.

Zhu Biao lowered his head and leaned his eyes up. The scene in front of him also shocked him.

"what is this?"

Zhu Biao couldn't help asking.

In terms of plant form or leaf form, Zhu Biao really doesn't know as much as his younger brother Zhu Wei.

"Brother, what you saw was the leaf you picked just now."

Zhu Wei replied from the side.

His words were a little excited, but because Su Jing and Zhu Biao were beside him, he restrained himself.

"Leaves? I picked them?"

Zhu Biao was startled, a little unbelievable, and read it carefully several times.

Only then was it confirmed that it was indeed a leaf.

"Master Su, the students bow down!"

Zhu Biao raised his head and said respectfully to Su Jing.

Zhu Su also followed suit and said: "Students bow down."

"Okay, let's do this first, you can open the door and open the window."

Su Jing was also very tired holding the mirror, besides it was still very dark.

The effect he wanted has been achieved.

The shock in the big eyes of Zhu Biao and Zhu Wei made Su Jing very useful.

Such a shock, Su Shi only felt that he deserved it.

After all, under such crude conditions, it is not amazing to be able to produce a microscope?

Zhu Biao and Zhu Wei were a little bit unfinished, but they still obeyed Su Jing's order and opened the door.

The sun shone again, and Su Jing walked in front of the two of them.

Zhu Biao and Zhu Wei looked at Su Jing, only feeling that Su Jing seemed to be radiant and extremely dazzling.

"Master Su, what is the name of this thing?"

Zhu Biao asked Su Jing.

Su Jing said with a smile: "This object is called a microscope, and it is specially used to observe subtle things, so it is called a microscope."

microscope!
"Micromicro, what an apt name."

Zhu Biao read it and said sincerely.

Zhu Wei looked at the crude microscope, just like looking at a treasure.

Su Jing saw Zhu Wei's love, a child who loves botany, likes microscopes, that's not a matter of course.

"Niu Su, how about this microscope?"

Su Jing asked Zhu Xi.

Zhu Wei said very seriously: "This is a divine object!"

"it is good."

Su Jing smiled and said: "Then I will send you off."

Note: The author personally made the self-made telescope for his niece. It is indeed possible. The details in the book are not complete, and it is slightly exaggerated, but not much. If you are interested, you can check it yourself.
