Chapter 121 Microscopic Observation

Allen himself went out and made microscopes by hand.

Using a steam engine as a power grinder, a large piece of optical glass is ground into a lens with a diameter of about [-] mm.

Its magnification is identified by identification technique, and its matching objective lens is made. When the two are combined, the magnification is more than 200 times, and there are more than 400 times of combinations.

Grinding lenses is a technical job, and inexperienced orcs can't do it well. They can only learn [-]% to [-]% by standing by and observing, and then slowly grind the optical glass they made themselves.

Then make a tight and simple iron tube frame, install the two lenses on the frame, and operate it in a short time, and the microscope will be formed.

After finishing this thing, it was already one or two o'clock in the afternoon, and the primary school biology class was still waiting for him to talk about it.

……

school.

The little orcs sat in rows. Since there were more and more teachers attending five classes in a row, the number of teachers in the biology class gradually increased, and each class could be arranged, so there was no need to sit together to listen to Allen's class.

Although it was not as lively as the crowded classrooms a few days ago, the appearance of the microscope made the students exclaim.

In the first class in the afternoon, Alan chose to attend the class with the most orcs in the fox village, and invited the priests of the fox clan to come to the class by the way.

The fox priest saw the power of the blast furnace that day, and he lost a lot of weight. When he came to the door of the class, everyone saw the fox priest with a haggard face.

"Master Alan, I want to go back to work." Priest Fox sat in the back row feeling uncomfortable, and wanted to go back within ten seconds after sitting down.

At present, his job is the supervisor of a certain area of ​​the cement road, supervising the work of the slaves, which is considered a relatively leisurely job and not very heavy.

"This lesson is very important. I suggest you listen to it and get started with it." Allen was unwilling to let him go, and the fox priest could only glance at Hood. Priest Hood looked at the ceiling, pretending not to hear look.

Hood is more like an old fox than he is, and the priests of Fox Village have no more, so they have to stay.

When the microscope was moved to the teaching platform, the little foxes blinked and stared at the microscope.

"Teacher, is that a microscope?"

"Yes, this is a microscope."

Allen nodded. He had drawn a picture of a microscope on the blackboard when explaining cells, so the orcs were not completely ignorant.

"A microscope that can see cells."

"Do the cells really exist? I really want to see."

The fox tails of the little foxes were already wagging, and most of the children's tails were in the shape of a curved question mark, while the dozen or so biology teachers in the back row formed straight tails of exclamation marks, both excited and eager to see.

The priest of Fox Village glanced at the microscope on the stage, and his fingers trembled again.

cell?

It seems that the basic structure of organisms discussed in the first class, in theory, each orc is composed of small cells.

"Can I also see cells?" The priest of Fox Village couldn't believe it. He was very conflicted. He believed that Alan was qualified to challenge the gods, and he also believed that supernatural objects should not be desecrated by ordinary orcs.

"Everyone has a chance. Let the teachers in the back row come up and manipulate it first. Everyone learns what the teachers do, and then it will be your turn."

As soon as he finished speaking, the dozen or so teachers in the back row were stunned for a moment. They thought Alan would focus on explaining the microscope for 10 minutes, but they didn't expect to let them practice it as soon as he came up.

Natasha was the first to go up to use the microscope, and she saw this metal object made of iron sheets. It was long and ugly in shape. If it was a modern person of later generations, it would definitely despise this crudely made thing.

Fortunately, the aesthetics of the orcs is still at a low level. In their eyes, the rough style of the steel industry is a sacred object and a beautiful existence.

Natasha touched the microscope carefully, with slight force and slow movements, for fear of falling apart, which made Allen dumbfounded.

"Look at the microscope with your eyes, and adjust the brightness of the bottom mirror to adjust the brightness. Today we are observing plant cells. Be careful, everyone. I just scraped some materials from this grass, so I didn't fool you."

Allen took out a plant of grass, and then Natasha scraped it lightly with a dagger, spread a thin layer of "green" onto a very thin transparent glass slide, and placed it on the small hole in the center of the stage .

"The mirror of this microscope is not detachable, so the replacement of the objective lens is not necessary. In the future, new microscopes will have the steps to replace the objective lens. For the time being, we use a high-power microscope or a low-power microscope."

The microscope Allen made is not a modern microscope, and there is no objective lens converter, so he brought two microscopes, one with low magnification and the other with high magnification.

"Yes." Natasha continued to look at the things in the microscope with her eyes, but saw nothing.

Allen taught her to use the up and down screw knob next to it to make fine adjustments slowly, and it took more than ten seconds to see the object image in the microscope.

It was a circle of closely connected green polygonal "walls", with some round and large cell nuclei inside, and even some unknown small objects in the liquid. She didn't know what they were.

"Is this the cell? It's amazing." Natasha saw the cell structure of the plant and felt her world view was overturned.

Although Alan's biology overturned his world view in class before, his concept was in a half-confused state, and now she really believes in the theory of biology.

The body of every organism is composed of countless cells, so does this mean that mysterious supernatural powers also originate from some strange cells?
Natasha's thoughts began to diverge, and she froze in place for a long time.

"Natasha, have you seen it clearly? If you don't see it clearly, let me do it for you." Allen's voice rang in her ear.

"Ah, oh, I can see clearly, very clearly." Natasha moved her eyes away, feeling her brain a little swollen.

"I'm going to take a rest." Natasha returned to the back seat, her mind was in a mess.

Ivan and other orcs had already had their hearts itchy, and couldn't wait to ask: "Natasha, is that cell real? What does it look like?"

"The cells are real, just like the ones drawn by Master Allen in class." Natasha's mind was full of weird thoughts, and she sat in her seat to diverge her thoughts after a casual sentence.

The priest of Fox Village who was sitting next to him was a little uneasy. Do mortals really see the cells?It's not a hoax.

He glanced at Alan, only to find that Alan was looking at him and ticking his fingers at him.

"It's your turn for the priest. Let's take a look at the cells. Maybe after reading it, you will change your concept of worshiping plants." Allen laughed.

The fox priest's throat moved slightly, so he could only bite the bullet.

Worship plants?

The White Blood Sacred Tree will bleed white blood, which is a manifestation of miracles. After seeing it once, you will naturally become a loyal believer of the White Blood Tree.

Fox Priest approached the microscope with the chaotic thoughts in his mind, looked into the eyepiece with his eyes, and immediately saw polygonal cell wall cells, which were closely connected, with inexplicable transparent substances flowing inside.

The fox priest let out an exclamation, looked away, and looked at the objective lens at the end of the microscope. There was a small slice of green leaf cells, which was placed in the center of the transparent thin glass slide, eroding his conception brightly.
