Alan personally went out and made the microscope by hand.

A steam engine is used as a grinding machine to grind large pieces of optical glass into lenses about 30 mm in diameter.

The magnification of the two is used to identify its magnification, and the objective lens is matched with it, and the combination of the two is more than 200 times and more than 400 times.

Grinding lenses is a technical job, inexperienced orcs can't do it well, standing next to observe can only learn three or four percent, and then slowly grinding their own optical glass.

After that, a tight simple iron tube shelf is made, two lenses are placed on the shelf, and the microscope is formed after one operation.

It was one or two o'clock in the afternoon to finish this thing, and the biology class in elementary school was still waiting for him to speak.

……

School.

The little orcs sat in rows, and since there were more and more teachers who listened to five classes in a row, the number of teachers in biology classes gradually increased, and each class could be arranged, so there was no need to share a table to listen to Alan's class.

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

In the first class in the afternoon, Alan chose the class with the most orcs in Fox Village, and invited the fox priest to come to class by the way.

The fox priest saw the power of blast furnace iron smelting that day, and the whole person was much thinner, and when they came to the door of the class, everyone saw the fox priest with a haggard face.

"Lord Allen, I want to go back to work." The fox priest sat in the back row uncomfortably, and wanted to go back after sitting down for less than ten seconds.

At present, his job is to oversee an area of the cement road, supervising the work of slaves, which is not very heavy if it is more leisurely.

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

Hood was more like an old fox than him, and the priest of Fox Village had no choice but to stay.

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

"Teacher, is that a microscope?"

"Yes, that's the microscope."

Alan nodded, he had drawn microscope graphics on the blackboard when he was explaining cells before, and the orcs were not completely ignorant.

"A microscope that can see cells."

"Do cells really exist, I want to see it."

The foxes of the little foxes have already waged their tails, most of the children's tails are in the shape of curved question marks, and the dozen or so biology teachers in the back row are standing up into straight exclamation mark tails, that is, excited and eager to see.

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

Cell?

It seems to be the basic structure of living organisms discussed in the first lesson, and theoretically each orc is made up of small cells.

"Can I see the cells, too?" The priest of Fox Village couldn't believe it, he was conflicted, believing that Eren had the qualifications to challenge the gods, and believing that supernatural objects should not be blasphemed by ordinary orcs.

"Everyone has a chance, let the teachers in the back row come up and manipulate it first, everyone learns how the teachers do it, and then it's your turn."

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

Natasha was the first to go up and use the microscope, and saw that this metal creature made of iron sheets, long barrel shape, and ugly appearance, if it were a modern person in later generations, he would definitely be very disgusted with this kind of poorly made thing.

Fortunately, the aesthetic of the orcs is still of a low level, and the rugged style of the steel industry is a holy object and a beautiful existence in their eyes.

Natasha carefully touched the microscope, with slight force and slow movements, for fear of falling apart and making Alan cry and laugh.

"Look at the microscope with your eyes, adjust the brightness of the reflector at the bottom level, today we are observing plant cells, everyone is optimistic, I will scrape a little material from this grass, I didn't bluff everyone."

Alan took out a piece of grass, and Natasha gently scraped it with a dagger, spreading a thin layer of "green" onto a very thin clear glass slide, placing it on the central upper hole of the stage.

"The mirror of this microscope cannot be removed, so forget about replacing the objective lens, and the new microscope will have the steps to replace the objective lens in the future, and now we will temporarily use two high-power microscopes or low-magnification microscopes."

The microscope that Allen made was not a modern microscope and did not have an objective converter.

"Yes." Natasha continued to look at the microscope with her eyes and saw nothing.

Alan taught her to use the lifting spiral knob next to her to slowly fine-tune, and it took more than ten seconds to see the image in the microscope.

It was a tightly connected green polygonal "wall" with some large round nuclei in it, and even some unknown small objects in liquid, which she didn't know what they were.

"Is this a cell, it's amazing." Natasha saw the cellular structure of plants and felt that her worldview had been overturned.

Although she had been overturned by Allen's biology in class before, his concept was in a semi-confused state, and now she really believes in the theory of biology.

Every organism is made up of countless cells in its body, so does this mean that the mysterious supernatural powers also originate from some strange cells?

Natasha's mind began to diverge, and she froze in place for a long time.

"Natasha, do you see clearly, let me do it for you if you don't see it clearly." Alan's voice rang in her ears.

"Ah, oh, I see it clearly, very clearly." Natasha looked away, feeling her brain swell a little.

"I'm going to take a break." Natasha returned to her back seat, her mind racing.

Ivan and the other orcs were already itching, and couldn't wait to ask, "Natasha, is that cell real, and what does it look like?" ”

"The cells are real, just like what Master Allen drew in class." Natasha's mind was full of strange thoughts, and she sat in her seat and thought differently with a casual response.

The priest of Fox Village sitting next to him was a little uneasy, mortals really saw the cells, not bluffing.

He glanced at Allen, only to see Allen looking at him, hooking his finger at him.

"Priest, it's your turn, come and see the cells, maybe after reading it, it will change your concept of worshipping plants." Alan laughed.

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

Worship plants?

The White Blood Sacred Tree will shed white blood, which is a manifestation of miracles, and after seeing it once, it is natural to become a faithful believer in the White Blood Tree.

The fox priest approached the microscope with the confused thoughts in his mind, looked at the eyepiece with his eyes, and immediately saw the polygonal cell wall cells, which were closely connected, and there was an inexplicable transparent substance flowing in them.

The fox priest sighed and looked away at the end of the microscope at the end of the objective, where there was a small slice of green leaf cells, which was in the center of a thin, transparent glass slide, and it was brightly eroding his ideas.
