I became a witch, but I started the industrial revolution

Tina has abolished all taxes, and all harvests belong to the farmers personally. Which farmer would give food to the town for free?

Moreover, because the influence brought by the Holy See in the past was too bad, the church itself was in a state of being condemned by everyone in the villages and towns, and it had completely lost control over the grassroots believers.

By the time they realized the problem, the city had already begun to fall into depression. The insufficient supply of food and other supplies caused prices to skyrocket, and famine began to spread rapidly.

Cities are usually the meeting points of surrounding villages and towns, and some cities simply have only military functions.

Without exception, they all rely on the food and agricultural products grown on the land in the surrounding towns and villages, and it is impossible for them to feed so many residents on their own.

Under duress, many city lords chose to open their granaries and release grain to prevent the city from falling into chaos. However, many stingy nobles chose to turn a blind eye to this, and the city began to fall into turmoil.

This is a blatant conspiracy. Either you open the warehouses to feed the people in the city and stabilize the morale, but then the consumption of food reserves will inevitably skyrocket.

Or you can choose to hide and turn a blind eye, waiting for the people's guides to open the city gates from the inside and let the peasant army in to besiege the city.

No matter which nobles were chosen, they would feel uncomfortable, and Ovinia III was venting his anger in the palace. The sudden rise of the rebel army cut off the capital's aid line to the border lords.

At the same time, they were strategically isolated from the kingdom and became isolated territories.

Moreover, Tina's heartless behavior of beating the manor owners and dividing their land and food made it extremely difficult for the counterattacking lord's army to regain the lost territory.

To recover a piece of lost land, the land that had been distributed before could be taken back and the farmers' association could be disbanded, but if they wanted to take back the distributed grain and cloth, they could only resort to violence.

Killings, food robbing, rape, and various tortures were carried out against the middle and high-level leaders of the farmers' association. They also wanted to restore their previous rule through violent authority.

However...how can someone who has seen the light be willing to fall back into darkness?

What Tina and others have done is like a seed that has taken root deeply in the hearts of every civilian, and one day it will break through the ground and grow into a towering tree.

Chapter 75: Cross-era, nitrocellulose.

At this time in Seris, Medea took a special train to the city of Astar for inspection.

However, Medea was not allowed to enter the laboratory and could only watch the finished products from outside...

As the former base camp, there are quite a number of scientific research departments here that have not been relocated, such as the more dangerous chemical department.

The reason why she came here today was because a groundbreaking technology had been cracked.

【Nitrocellulose Preparation】

This is the most important component of the so-called smokeless gunpowder. Smokeless means there is basically no residue.

Black powder will leave a lot of solid residue after burning, but smokeless powder will only leave some gas.

The reason why Medea has always looked down upon black gunpowder is that this thing is really not very useful.

The fundamental reason why she pinched her nose and used Maxim was that the metal manufacturing process of bullets in the past was not very precise, and the caliber was at least ten millimeters, so black gunpowder was used.

However, only the first-generation Maxim rifles she had were large enough in caliber to be used in full automatic mode. The rifle still needed to be stopped after firing a few rounds to clean the barrel, otherwise it would easily cause the barrel to explode.

The use of black powder will inevitably produce smoke. The dirty smoke will lead to poor accuracy. The smoke residue will be corrosive after absorbing water and damage the barrel and parts. The burning rate is low, etc. There are problems everywhere.

The material composition of smokeless gunpowder allows it to burn more completely. The greater the pressure, the faster the burning speed, and the more concentrated the energy burst.

The most intuitive comparison is that if the initial velocity of a black powder bullet is 400 meters, then the initial velocity of a smokeless powder bullet is meters.

With a higher initial velocity and kinetic energy, she can reduce the mass of the bullet, so that the bullet has a straighter trajectory. The smaller the ammunition, the lighter it is, and the soldiers can carry more ammunition.

The difference between magic crystal powder and black gunpowder is not as outrageous as before. Magic crystal can be used in other fields instead of being a consumable like propellant.

Of course, the preparation of nitrocellulose is not that simple.

Only after the development of blast furnace steelmaking, coal smelting and petrochemical technologies did Seres gain the ability to produce nitric acid and sulfuric acid.

Nitric acid, sulfuric acid and cotton make the most basic nitrocellulose. If it could be used after being prepared to this point, then Medea would not have to wait until now.

The nitrocellulose produced in this way still has nitric acid residues in its nitrocellulose and cannot be touched by hand. However, if it is produced directly in the factory, it will decompose nitrogen dioxide and release a large amount of heat when exposed to heat or light.

If the heat is not discharged, it will cause spontaneous combustion or explosion. What would the scene be like if a warehouse of gunpowder exploded?

These shortcomings mean that it is destined to remain in the laboratory for the time being rather than be used on the battlefield.

Later, the biggest task of the entire Chemical Research Department of Seris was to subdue this explosive girl, and it took them nearly ten years to do this.

After the nitrocellulose is produced, it must be soaked in water and washed repeatedly to clean off the residual sulfuric acid or nitric acid on the nitrocellulose.

After washing, the cotton is pulped using a steam engine to break up the fiber tubes and obtain clean and beautiful nitrocellulose.

But this is not enough, it is still too fluffy and ignites very quickly, making it unusable as a propellant, so it needs to be gelled again.

The ignition point of nitrocellulose is only 170 degrees, so it cannot be burned with fire or water because it is insoluble in water. Finally, alcohol and ether are used to dissolve nitrocellulose into a colloid.

Then use a machine to repeatedly knead, press and stir the colloid to remove gaps and bubbles in the fibers, which will differentiate into two types of fibers: soluble and insoluble.

Finally, mix 7% insoluble nitrocellulose and 3% soluble nitrocellulose together, and use the soluble nitrocellulose to fill the gaps and bubbles in the insoluble nitrocellulose.

This maximizes the compression of the volume of the nitrocellulose, making it no longer as fluffy as a cotton ball, but this is not the end.

There is also the problem of burning too fast. Add paraffin wax to wrap the surface of nitrocellulose and then add some graphite powder.

Graphite is black and has good anti-static properties. Only then has nitrocellulose reached the quality required for use as military weapon propellant.

Nitrocellulose with added graphite is black particles, so many people mistake smokeless gunpowder with added graphite for black gunpowder. In fact, these are two different things.

The benefits of being able to produce smokeless gunpowder are enormous. First of all, all the rifles currently in service in Serbia can be completely eliminated.

Because smokeless gunpowder leaves no residue, it can be fed from a magazine, and the design of the firearm can be made simpler with a bolt-action lock. New rifles no longer require searching for bullets and loading them one by one.

In other words, magazines can be produced by specialized factories, with workers installing bullets into them in advance, and then packed into boxes for storage and transportation. This can visibly reduce the pressure on logistics.

There are also many benefits for soldiers. The range is almost doubled compared to black powder, the lethality is also stronger, the firepower is more sustained, and the improvement in survivability and firepower is visible to the naked eye.

Moreover, smokeless gunpowder has high energy density and fast initial velocity, which further reduces the volume and weight of bullets and shells, and the size of artillery can be further miniaturized and reduced in weight.

It also made the recoilless gun that Media had envisioned possible.

The principle of the recoilless gun is actually not difficult. Its propulsion principle is not much different from that of traditional artillery firing, but it cleverly utilizes the kinetic energy of the propellant of the shell.

The chamber of a recoilless rifle is usually two times larger than the barrel itself because it has to form a cavity around the chamber.

After the propellant is activated, energy emerges from the holes and the shell is fired out of the barrel. The kinetic energy of the shell as it is ejected by the propellant is normal recoil.

However, when the energy of the remaining propellant impacts the cavity and turns to be ejected from the gas guide hole reserved in the rear breechblock, a forward reaction force will be formed to offset the force of the ejection of the shell.

This is the principle of one type of recoilless gun.

However, the principle is simple but that is relative. If black powder is used, solid residue will easily clog the mesh holes. In that case, this mesh spray hole design is like winking at a blind man.

In fact, black powder can also be used to make a recoilless gun barrel, but the idea is to use it once, so it doesn’t matter whether the barrel will be damaged or not, and it doesn’t matter what kind of propellant is used.

But with a short attack distance of 30 meters, both the gun barrel and the soldiers have to be disposable...

Another advantage of this grid design is that it can enlarge the aperture, and the principle remains basically unchanged.

This means that it can be retrofitted to various existing armored vehicles to take firepower to a higher level.

The disposable recoilless gun barrel will only have a suitable range after being developed into a rocket-propelled type, so it is not considered for the time being.

Anyway, the grid-like volume can be designed to be small enough for individual soldiers to use. These are the weapons that Medea uses to deal with those magic mechas.

With smokeless gunpowder, rifles and machine guns can be upgraded

With field artillery and mortar fire coverage and tracked armored vehicles equipped with recoilless guns and machine guns cooperating with infantry advance, the mechanized force has taken shape.

Chapter 76 Cat All Terrain Vehicle

However, the troop composition envisioned by Medea was not mechanized enough, because the infantry did not have vehicles in the strict sense.

The mobility of wheeled trucks used previously was not very good. The thick snow would cause the wheels to slip from time to time, the horsepower was insufficient, and the quality of parts was unstable.

In other words, the opponents she encountered relied on walking on two legs, and the cavalry had no room to operate in the snow. Otherwise, if she had replaced it with a mobile team, she would not have been able to play any mobile and interspersed tactics.

Now that winter is over and the snowmelt season has begun, the roads are slippery and muddy.

And after living there for so many years, Medea discovered that the soil on the great plains of the subcontinent was relatively loose, and if you didn't walk on the main road during the rainy season when the soil was moist.

In areas outside the main road, the water is so deep that an average person cannot even pull their foot out.

This is also the reason why Media has not paid much attention to the development of tanks. With such a bad road, such a bad engine and such a heavy weight, if a tank breaks down on a bad road, it can only be abandoned and cannot even be towed back.

Therefore, if you want to perform mechanized maneuvers in such a road environment, in addition to using tracked vehicles, you also need a smaller jeep-type infantry vehicle, preferably one that can be used in all terrains.

The weight should be very light, around two tons, the load capacity should be one ton, the speed should be 50-70 kilometers per hour, the wading depth of mud and water should be about 30 mm, and the power engine should be within four cylinders.

After considering all the conditions, she has come up with a very suitable configuration.

It is small in size, so apart from the frame, nothing else needs to be installed. The only difficulty is that the gearbox problem needs to be solved.

The configuration is simple, the manufacturing difficulty is low, and the cost is not high. Two or three vehicles can be allocated to each team for use, with two vehicles carrying people and one vehicle carrying supplies.

Large-scale modular manufacturing can further reduce costs, and modular mass production of engine units can be used to simplify maintenance.

The soldiers in the platoon decide on the other accessories and match them according to local conditions. As for the name of the vehicle, it is called Cat All-Terrain Vehicle, because she happened to have a kitten.

Media has done something similar before. The tracked armored vehicles are manufactured in a modular manner. The factory is only responsible for producing the basic models, which are then transported to the local area for the local troops to choose the installation plan themselves.

They can only choose the basic aspects such as full track, half track, whether the carriage is open or not, etc., and the rest of whether you want to install a machine gun or a cannon in the carriage is completely ignored by Mitia~

This kind of basic welding work can be done by any factory. There is no need to waste the working hours of the manufacturing factory. Standardization and high efficiency are the core factors for explosive productivity.

The oil reserves are abundant, and the radio of the Electronic Engineering Department has been successfully trial-produced. If the overall vehicle is replaced, Seris will be able to achieve mechanized coordinated maneuvers in the subcontinent.

In the civilian sector, agricultural machinery factories have also been established in various states.

However, due to the technical level and number of workers, the efficiency of manufacturing production is far lower than the demand. Currently, it is only guaranteed to be available, and there is still a long way to go before it is popularized.

The tractors produced can only be handed over to local troops first, and they will go to the countryside to help the disabled and widowed families with farming first, and then they will be opened to villages for loan.

However, if we lend it to the other party, they must know how to drive it. In the end, it was decided that each village would send its own people to gather in the military camp to learn.

"..."

After nearly half a month of sailing after leaving the Seris Navy, Eunice and others finally successfully docked at the port of Bonwich.

After they reported their identities, the soldiers of the Kingdom of Ovinia quickly invited them to rest in the luxurious reception room of the City Lord's Mansion.

The ponytailed man looked at the servile soldiers around him, crossed his legs and complained, "Finally, I met a normal person."

"What the hell is that Seris Kingdom? I've never been so humiliated since I became a pilot."

"You should say less. Fortunately, the captain was out negotiating at that time. If you had gone, I think we would still be swimming in the sea now." The sturdy man advised in a muffled voice.

Hearing the burly man's words, the ponytailed man recalled the huge ship that was twice the size of theirs, and a trace of fear rose in his eyes, but he did not admit defeat:
