Release that Witch

205. Chapter 205 Microscope

    After repulsing Timothy’s troops, the small town returned to calm.

    Roland selected three people from the City Hall Ministry of Education, plus two teachers to form a team, with Soraya photocopied books to Longsong Stronghold. No matter how effective it is, he finally took the first step in assimilation of stronghold.

    Although Petrov was not good at commanding the battle, he did perform well in the administration. In just one week, two thousand recruited handymans came to small town under the escort of Knight. If it weren’t for the second batch of ten sets of furniture, Roland couldn’t make up his mind to establish a hard road between the two places. Now, he finally has a chance to squander.

    This road was named Roland as the kingdom avenue and is fully responsible for the Ministry of Construction Karl. Its structure is exactly the same as that of the small town street. It is a cement stabilized gravel layer. In the age when there is no heavy truck, this kind of road is enough for the transportation task. . Moreover, the drainage performance is good, and asphalt or concrete can be added in the future according to the situation.

    On the construction materials, four steam engine-driven mills replaced the manpower and crushed the stone, producing dozens of tons of crushed stone every day. The weak transportation capacity has restricted the further increase in production. So many stones require more than 100 people to take a horse-drawn carriage for one day before they can be sent to the construction site. If it is a later road, the main road slag truck can be transported in one car.

    In addition to the four-seat clay bricks in the furnace area, the other blast furnaces have been put into the production of cement powder. After many component tests and iron powder supplied by the mine, the cement produced by small town is far away in terms of quality and stability. More than the original batch.

    However, the brigade and cement powder transported by the brigade also brought a lot of negative effects to the small town. The most serious problem is the dust. Until the afternoon, only a little scratching the wind, you can see the dense dust floating in the sky, the street has turned pale yellow. Although most townspeople don’t mind such a situation, there is nothing worse for Roland than to close the doors and windows on a hot summer day.

    The carriage carrying the cement and gravel was quickly fitted with a cover plate to reduce the scattering during transportation. At the same time, under the promotion of Leaf’s ability, the small town was covered with shade in just a few days, and the leafy sycamore trees were arranged symmetrically along the street, looking green and looking. In addition, HMS Roland called the entire citizen to actively sprinkle water to reduce dust, and this problem was quickly improved.

    The straight line distance between the two places is less than 70 kilometers, but considering the road to avoid the foot of the Impassable Mountains, the total length of this road is about 100 kilometers, and the estimated construction period is one year. With quality roads, some vehicles can come in handy – like bicycles and steam cars.

    In his conception, development education or road construction is a measure that connects the two places together, just like the town integration that is strongly promoted in later generations. After the development of the land between the two places, Longsong Stronghold and Border Town will merge into one huge city. If he can turn the hills in the south end into a part of the city and then open the edge mountains, they will even have a estuary.

    Of course, opening up so much land requires more people, and in order to cope with possible future wars, the city must provide a large number of workers for industrial production while self-sufficiency in agriculture. Under preliminary calculations, he needs to introduce about 100,000 people, and Greycastle’s largest city, Kingdom Capital, is only about 20,000 to 30,000.

    Roland turned his attention to Greycastle north and the southern region. Both places have experienced war. When the winter falls, there will probably be a large number of refugees who are short of food and clothing. Simply feed your hunger-filled food and warm accommodation into the Border Town. Even the refugees of Eternal Winter and Wolf Heart are also under his consideration. To this end, he also wrote a letter to the merchant Margery, let her help inquire about the situation of the two countries.

……

    After writing down the recent development plan, the prince folded the paper into the drawer and stretched out. He decided to go to the Anna room to see how her lens was cut.

    Since understanding the reasons for Soraya’s evolution, he has planned to make a microscope that can observe the structure of cells.

    If you can see the wonderful microcosm with your own eyes, it may trigger more witches to evolve new abilities, and if you don’t help, it will arouse their interest in learning.

    For the production of microscopes, two convex lenses for magnifying the target are not difficult. The difficulty is that the focal length of each hand-polished lens is different. Therefore, matching the eyepiece and the objective lens is delicate and requires repeated adjustment of the two lenses. distance.

    After briefly describing the principle of convex lens imaging, he handed Anna several crystals of excellent texture, allowing her to try to cut the lenses and measure their focal length. Now, three days have passed, and to what extent Anna has done it now, Roland is full of curiosity.

    Walking to the door of Anna’s room, Nightingale smiled at him and stood against the wall, seemingly indicating that he would not follow up – since she reduced her stealth time, Roland didn’t have to guess the other’s whereabouts, and Anna alone. At the time, Nightingale will always choose to stand farther.

    Pushing open the door, Anna is sitting at the table and playing with a metal tube.

    And how was it?He asked as he stepped forward.

    Just after asking for the exit, Roland stunned, and saw only a few instruments on the table that looked like microscopes, and they were very close to the schematics they had drawn.

    “According to the drawings you gave me to do a few trial products, indeed can see many ordinary difficult to find details,” she raised her head, slender bangs to one side of the slide down, “I used it to observe the paper, leaves and water, found that they and weekdays in the appearance of a big difference.” “-After a hot-air balloon trip, Anna made it easy for her to stop using honorific when they were alone.

    “How did you make it,” Roland said with amazement. “The schematic is just a rough outline.”

    “The outline is enough,” Anna laughed. “You see, as long as the eyepiece and the objective are fixed at a suitable distance, they can be magnified, and then fixed with iron pipes, and the main body of the microscope is completed. When I tested the lens magnification, I found that the objective lens and the observation target must be kept within a certain distance to see a clear image, and the hand shake would be blurred. As you can see from your diagram, you need a shelf to hold the lens barrel, and the table below the target can be moved up and down to get the best object distance. ”She is paused, “The piece at the bottom of the schematic is hard to understand. Can you tell it what it is for?”

    Roland glanced at the drawings and found that he had made a mistake—it was a mirror that was used to increase the light that passed through the target. In this era, the mercury mirror has not been invented. The general noble is still finished with a bronze mirror or an iron mirror. In the palace, silver is placed on the back of the glass to get a better reflection. Even without this mirror, the microscope can be used as long as there is enough sunlight.

    After explaining it in detail, he couldn’t help but feel Anna’s amazing comprehension. Based on the rough outline, he made a finished product that is close to the whole body. It is impossible for him to do this.

    Looking at the white neck of the other side when he looked down at the new tube, Roland couldn’t help but get together and wanted to kiss, but she pressed her hand on her face and gently pushed it away. “Be a meeting, Your Highness, I am busy.”

    Hmmm……Alright
