Release that Witch

After repulsing the troops of Tiffco, the town returned to calm.

Roland selected three people from the City Hall Ministry of Education, plus two teachers to form a team, with a copy of Soroya's books to go to the long song fortress. No matter how effective it is, he finally took the first step on the assimilation fortress.

Although Pei Luo was not good at commanding the battle, he did perform well in the administration. In just one week, two thousand road repairers who were recruited were coming to the town under the **** of the Cavaliers. If it were not for the second batch of ten groups of kiln put into production, Roland did not dare to 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 by Roland, and was under the responsibility of the Minister of Construction, Karl. The structure is exactly the same as that of the town street. It is a cement stabilized gravel layer. In the era when there is no heavy truck, such a road is enough to undertake transportation tasks. Moreover, the drainage performance is good, and asphalt or concrete can be added in the future depending on the situation.

On the construction materials, four steam-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 **** truck can be transported in one car.

In addition to the four-seat clay brick firing in the kiln 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 in the town is now of quality and stability. Far more than the original batch.

However, the delivery of gravel and cement powder by the brigade has also brought a lot of negative impacts to the town. The most serious problem is 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 this 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 the ability of the leaves, the 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. This problem was quickly improved by the fact that Roland called for all democracies to sprinkle water.

The straight line distance between the two places is less than 70 kilometers, but considering the road to avoid the foothills of the extremity mountains, the total length of this road is about 100 kilometers, and the construction period is expected to be one year. With quality roads, some vehicles can also come in handy, such as 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, the Long Song Fortress and Bianbu Town will merge into a huge city. If he can turn the hills at the southern 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 the preliminary calculation, he needs to introduce about 100,000 people, and the largest city in the gray town, Wangdu, is only about 20,000 to 30,000.

Roland set his sights on the northern and southern parts of the Grey Fort. Both places have experienced wars. When the winter falls, there will probably be a large number of refugees who lack clothing and food. Simply provide food for hunger and warm accommodation and you will be able to absorb them into Bianbu Town. Even the refugees of the winter and the wolf heart are also considered by him. To this end, he also wrote a letter to the merchant Margaret, let her help inquire about the situation in these two countries.

......

After writing 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 Soroya's evolutionary reasons, he intends to make a microscope that can observe the structure of the cell.

If you can see the wonderful microcosm with your own eyes, it may trigger more witches to evolve new abilities, and if they are not good, they 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, letting her 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.

Going to the door of Anna's room, the nightingale smiled at him and stood against the wall. It seemed that he was not going to follow up. Since she reduced her stealth time, Roland didn't have to guess the other's whereabouts. When Anna was alone. The nightingale will always choose to stand farther.

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

"How?" he asked as he stepped forward.

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

"I made a few prototypes according to the drawings you gave me. I can see many details that are hard to find," she looked up, and the slender bangs slid down to one side. "I used it to observe the paper and leaves." And the water, they found that they look very different in peacetime." Since the journey of the hot air balloon, Anna has no longer used honorific words when they are alone, which makes him feel very relaxed.

"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 amplified, 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 at 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 mirror. The tube is fixed, and the table below the target can be moved up and down to get the best object distance.” She paused. “The bottom piece of the picture is difficult to understand. Can you tell it what it is used for? ?"

Roland glanced at the drawings and found that he had made a mistake. It was a mirror used to increase the light that passed through the target. In this era, the mercury mirror has not been invented. The general aristocrats still use copper mirrors or iron mirrors to organize the appearance. Inside is a silver foil attached to the back of the glass for 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."

"Oh... okay." (To be continued. If you like this work, you are welcome to come to the starting point, your support is my biggest motivation. Mobile users please read.)
