Early the next morning, Donner and his party left Santan School of Magic with more than a hundred children, leaving Merkel there. Pen ~ fun ~ pavilion www.biquge.info

In the next few days, Merkel, with Laurent's assistance, will select hundreds of children from the remaining children to be trained as a talent pool for all levels of administration.

The system of land reform, which began in late October of that year in the three northern provinces, was resisted, consciously or unconsciously, by middle- and lower-level officials in the three provinces, as Downer and Wesley expected.

The bureaucracy, which used to work smoothly, is now corroding and rusting: it is becoming more and more difficult for the voice of the people to reach Merkel, and it is becoming more and more difficult for Merkel's decisions to be implemented.

In order to change this situation, Donner instructed Merkel to eliminate the most stubborn and conservative officials, co-opt the centrist composed of down-and-out aristocrats, and then select senior students from the Academy of Magic, and arrange these children who represent the interests of the common class to all levels of administrative units, and replace the aristocratic officials in a planned way while cultivating.

As for how to select talents, how to position these children in the existing administrative system, and how to train them to become qualified technical officials, each of these matters is related to the fate of these children and the future of the SAR.

But none of these things are Downer's fortifications, and what he has to do now is more important than that.

......

After the construction of the cement plant affiliated to the Institute of Chemical Engineering in Miwu Town, the construction of the town was like wings.

The small wooden building where Donner originally lived has been renovated several times, and once the Borg Mansion under Wesley's name, has now expanded in size and has become the town office of Misty Town.

Only a handful of people who know enough about the three northern provinces know that this small town office is the core of power above the governor's palace in Santan City.

However, the most mysterious part of Misty Town is not here, but the side of the town's road to the south, surrounded by a high cement wall, and a radius of two or three kilometers with "forbidden land" marked on the outer walls of the surrounding walls.

Construction began on the area as early as 639 in the year of the Femon calendar, but it was not until two years later in the winter that it was officially opened.

This winter, more than a hundred students from the Santan Academy of Magic and Wizardry were welcomed here, and since then, Donner and Wesley have been frequenting the area, and by the following spring, Una and Layla have moved from the Stone Villa.

Not many people know what's going on here, and compared to the land reform that is in full swing in the three northern provinces, the little forbidden land surrounded by high walls seems too quiet compared to the more than 200,000 square kilometers of land reform that is in full swing in the three northern provinces.

In the spring, the Lingbei Machinery Factory received two production tasks from Donner: a gravimeter and an anemometer.

The structure of both instruments is very simple.

The principle of the gravimeter is the same as that of the spring scale, except that the spring is not connected to a hook but a metal block of fixed mass, and the gravity value is read out by the expansion and contraction of the spring block under different gravity conditions.

However, Downer's requirements required that the gravimeter be assembled in a three-degree-of-freedom gyroscope. Obviously, the purpose of this is to read out the gravitational acceleration value at any time in a bumpy environment.

The main body of the anemometer is a three-bladed fan connected to the tail fin, the wide tail wing allows the fan to always be orthogonal to the wind direction, and the pointer attached to the fan shaft spring can read the speed of the fan blades to determine the wind speed.

In addition to these two simpler instruments, Donner also took matters into his own hands and made a barometer using liquid magic gold instead of mercury.

In May, Danny, under Donner's instructions, used a newly produced gravimeter to measure the gravitational acceleration on each floor of the streets of Fog City, drawing a height-gravitational acceleration curve.

On this curve, the gravitational acceleration is 1.2 times that of Middle-earth at a vertical distance of 52 km, 1.5 times that of Middle-earth at 60 km, and 1.92 times that of Middle-earth at a vertical distance of about 69 km. (The gravitational acceleration of Middle-earth is about 1.1 times that of Earth, but Donner isn't quite sure because he doesn't know if the world's unit of weight is exactly the same as Earth.) ）

Danny's conclusion is consistent with Donner's personal experience, that gravity in the central factory of Fog City is not much greater than that of Middle-earth, but the further down it goes, the more rapid the gravity changes.

Donner took the curve that Danny had given him, and according to the direction of the curve, it extended to each side, and if it was expanded according to this curve, the gravitational acceleration would be reduced to three-quarters of Middle-earth, and the altitude would be hundreds of kilometers higher than that of Middle-earth.

This conclusion is also in line with Donner's feelings—at the Wall of Despair, he used to think of the sea beneath the cliff as the sky.

After getting the gravity change map from Danny, Donner used the magic gold barometer to measure the change in air pressure at different altitudes inside Fog City.

As he expected, the barometric pressure on the planet varies very little between different altitudes, and the barometer's pointer varies very little from Middle-earth to the Knights' Federation.

So, over the course of a month or so, starting in mid-April, Donner worked hard to create an extremely elaborate barometer with the help of the most skilled dwarf craftsmen. On this barometer, the change in air pressure at each kilometer of altitude up and down the fog city can be reflected.

So, on May 20th, just after the foggy period of late spring in Misty Town, the 3rd Engineering and Technology Progress Award, which had been vacant for four years, was awarded to the dwarf craftsman who assisted Donner in completing the magic gold barometer.

In early June, Donner inspected Moen's work at the Misty Chemical Engineering Institute, and for eight months since he received Donner's instructions at that meeting last fall, hundreds of people from all over the school were looking for a material that could be applied to ordinary cloth to improve strength and maintain a seal, while also meeting the requirements of being lightweight, heat-resistant, and resistant to aging.

Moen did an excellent job.

In the dense forests of the southern part of the Thorn Empire, there is a strange plant called the Thorn Gum Tree, which secretes a light yellow gum, dissolved in the diluted acid wormwood juice, and then added a small amount of animal fat to stir, add a natural alkaline ore called lazurite to neutralize the acid wormwood juice, and finally go through a series of steps such as heating and filtration, the resulting paint, its properties are almost completely in line with Donner's requirements.

Finally, as the autumn of 642 was approaching, a hot air balloon slowly lifted off from the town of Mist.
