Before Donn took over Ellington, it had long been a territory struggling at the bottom of the poverty line, and the people here had to be exploited and oppressed by successive temporary lords, not only did they not have enough food and clothing, but they also had few gold coins in their hands, and their lives were simply miserable.

After Don became a lord, the drastic reforms injected vitality into Ellington, and now the residents of Ellington have stable jobs, although the food reserves are still insufficient, but Fiona, with Don's permission, allocated funds to buy food from the nearby Casparmi Fort and the mountain town of Bein, so that the residents of Ellington can have enough to eat.

What's more, after eating a full meal, they have a goal and see hope.

Done's goal for Ellington has given everyone the motivation to work hard, and everyone participates and contributes their own strength in the hope of making Ellington a better place, which makes Ellington a vibrant territory as a whole.

However, any earthlings who have received compulsory education know that the food problem is a fundamental issue for the survival and development of a country.

As the saying goes, if agriculture is underdeveloped in Africa, we all have to make a difference...... Ahh If agriculture is underdeveloped and agricultural products are not abundant, no amount of wealth can make a country stable.

Hence the Kim K-la...... Ahh Eating enough is the first pursuit of human beings!

It is clear to Donn that a country with underdeveloped agriculture cannot become the most powerful country in the world, and it is the same with replacing the concept of a state with a territory.

They do not attach importance to grain production and do not store grain for the people. If war breaks out and the supply of food is cut off, then Ellington will be in chaos without a fight. Therefore, Ellington wants to be strong, and the food problem does not depend on external imports to solve, and relying on imports for food is equivalent to handing over his right to exist to others.

So importing grain from other towns and territories all the time is definitely not a long-term option.

There is a huge gap between the people at the bottom and the world where the top wealthy live in the world of Plandal, and the serious lack of productivity at the bottom has led to an extreme lack of food production and supply, so it is not only expensive but also difficult to buy food.

So. Reform in agriculture is necessary and urgent.

Don didn't study agriculture and didn't understand biotechnology, so it was impossible to expect him to make some kind of technological revolution. All he could do was to take what he knew on Earth and what he could use in Plandal.

As long as there is no mess. It works. And he was satisfied.

And getting out these agricultural machinery such as cultivators and combine harvesters to realize agricultural mechanized production is the first step he can think of.

As mentioned before, Don is not a mechanical major, but he knows the general shape and effect of these agricultural machines, and can even guess a little bit of the principle, which is enough.

Prandal has been developing in the world for nearly 10,000 years. The class holds the power and restricts the self-development of the people at the bottom. But there's no shortage of talent, it's inspiration.

And what Don wants to do is to become the one who breaks the confinement, transmits the spark of thought to them, and at the same time shares the magical power he has mastered, and accelerates the pace of development of this world.

He drew the outline drawings, wrote the functions, and then annotated the principles he could guess and think of, and then handed over the drawings to the professionals, that is, Brian, Edgar, who were engaged in forging, and Nokia, who was engaged in engineering.

After handing it over to them, there wasn't much Tang En could do, and he could only hope that they could reverse crack these farm machines from the drawings and "inspiration" he had taken out.

Now it seems that the results are very encouraging.

Klotto is worthy of being the most powerful master craftsman in the dwarf kingdom, and he led a group of assistants, according to the prototype drawings proposed by Donne, he really deduced the internal structure of these agricultural machinery backwards, and even added improvements after his own understanding in many places, making these machines more in line with the "aesthetics" of the dwarfs......

Well...... In fact, it is the miniaturization of the cockpit.

After giving them the reward, Donn asked Edgar and the other apprentices to sign a confidentiality contract, after all, the universal alloy is a very important thing, and leaking it will greatly affect Ellington's subsequent development.

As for Brian, this step can be saved.

Although this guy is a talker, the dwarf's discipline is still there, and he will not divulge the things that his friends told him to keep secret.

Brian took Don to the backyard, then pointed to a small circle of combine harvesters and said: "This is the sample we got out in the past few days, because it's almost time to harvest crops, so we gave priority to the combine harvester, but the power has not been determined, so we haven't been able to try." ”

Donn went up and looked, the place where the engine should have been installed was now empty, and the thing was still just an empty shell.

"I see, I'll be able to solve the power problem right away."

"Great!"

Nokia jumped up and rushed out directly: "I'll go back and inform Master Klotto, he said that you must contact him when you solve the power problem!" ”

Tang En was stunned.

Brian shrugged: "Understand, these little dwarfs have found a soulmate when they meet you, and they like to study this kind of thing the most." ”

Taking advantage of the fact that Master Klotto didn't come, Don began to ponder the problem with the engine.

As I said in the previous discussion with Kloto, although the explosive power of the internal combustion engine is very abundant, but now Brandal's existing processing technology is simply unable to make a working cylinder, and with Donn's knowledge reserves, he cannot make such a thing as an internal combustion engine engine, so he can only give up.

There was only one path in front of Don.

Although Purendal has electric magic and seems to be able to harness electrical energy, that requires finding a permanent magnet that is efficient and usable. With an efficient permanent magnet, he can use the magic array to convert magic into stable electrical energy to make a simple motor engine - he still understands the electromagnetic effect.

The benefits of the motor engine are to do work through the electromagnetic effect, with less friction loss and higher energy conversion efficiency, which seems to be a very good choice?

However, pay attention, but here it is, the difficulty of the motor engine is that the process requirements are high, and the material Tangen can't get it.

Someone said that there is no permanent magnet, and it is possible to use electromagnets.

Yes, yes, but if all electromagnets are used, how to solve the phase transformation of the current? Again, this is a big problem that cannot be solved, and Brandal does not have a smart chip that can be programmed to control the current phase.

So the only way Don can use wind energy is to use it.

Craft a turbo fan, then use the Wind Magic Circle to convert mana into stable wind energy to craft a turbo engine.

Turbine engines have high losses and low energy conversion rates because they do physical work, but in fact, because of the discovery of universal alloys, the use of wind energy is the best choice.

Lightweight, high-temperature resistant Mithril alloy has been made, isn't this an excellent material for turbofans and combustion chambers?

There is also a friction-resistant and corrosion-resistant magic iron alloy, which is not an excellent choice for bearings?

The pure gold alloy with high strength and toughness can just be used as the main structure of engines and various machinery!

The discovery of universal alloys will definitely be a revolution in the history of Plandal's development!

When designing wind energy pumps before, Tang En already had experience in training, but now he is just complicating the design of the pump and making it multi-stage...... Well, that's all.

That's right, Donn just wanted to get a turbojet engine for jet planes!

Although I know that there are a lot of complex physics knowledge and process requirements in it, it is not as simple as imagined, but ...... Who cares?

Now the key question is whether it can be used, not whether it will explode, right?

Explosions are completely unavoidable in the course of scientific development, and as long as they don't kill people (probably), the losses are completely acceptable.

"Hmm...... If you remember correctly, the simple partition is intake, compression, combustion, jet ......"

Don muttered while writing and drawing on the paper, first drawing the appearance of the aircraft engine in his memory, and then began to ponder the internal structure inside, turbine blades are naturally indispensable, and he also knows the fumarole, but what is the internal turbine structure? What does a pressurized combustion chamber look like? What is the principle? He doesn't know anything about these key points.

"(Chinese) It's really tangled......"

"Your Excellency?"

Fiona heard Done's broken thoughts, and her face was puzzled, "What were you talking about just now?" ”

"Nothing."

Tang En sighed, casually drew the pressurized structure of the multi-stage turbine blades that he finally remembered, and muttered: "I really want to strike and find a place to go chic, and in a hundred years, it doesn't matter if it is a flood or the end of the world......

Fiona understood this, and she immediately became nervous: "Lord Lord, you can't think like this, you are me...... The only hope for all of us! ”

The only hope...... This heavy sense of trust is not a good thing.

Tang En smiled bitterly: "I know, it's just a casual sigh." ”

"Emotion? What do you feel? ”

At this time, Kloto's voice suddenly came in, and the next moment, he saw Kloto with a broom on his head laughing and rushing in: "Don, I heard that you decided on the power source of the combine?" Where? ”

Don got up and smiled, "Master Klotto, you're really fast. ”

"Of course, if you can research a powerful and effective power source, the technology of our dwarf kingdom will also be of infinite use."

Croto laughed and said, "Besides, I heard from Nokia that you have made very good special materials here?" I'm also interested. ”

Tang En waved his hand: "In this case, let's study and study together, please!" (To be continued.) )
