Every time I come home, my wife is making garbage

Chapter 293 Alternative Fuels
Just as Zhang Jingyi solved the problem of work enthusiasm for the slaves.

Elizabeth and Antonio also came to the mine where the ogres worked and announced to them that "they were no longer slaves" and "had regained their civilian status."

Although the gnolls did not have such a crazy talent as "selfishness", they also had emotions. The moment they heard that they were no longer slaves and would be paid for their future work, they also burst into huge cheers.

I am more motivated at work.

Although they cannot increase their work efficiency by 4 times like humans, they have no problem increasing it by 2 times.

Antonio watched this scene and couldn't help but sigh: "Your Majesty! You see, no matter what race a person is, once they can be restored from slaves to civilians, they will be very happy. This system... may be the key to our overthrow of Ugumante and the success of restoring our country."

Elizabeth: “Oh?”

Antonio: "As long as we promote this system, we can easily win the support of a large number of slaves. Wherever our army goes, I am afraid that the slaves will desperately help us. Even in front of the two armies, the enemy's slave army will rebel on the spot."

Elizabeth nodded thoughtfully: "My teacher, do you mean that this system will also become a weapon for us to disintegrate Ugumantai?"

"Exactly!" Antonio: "His Majesty the King has an interesting idea. He said that advanced productivity will always defeat backward productivity. Advanced system will always defeat backward system. It is not a bad idea for us to use the system as a weapon to attack Ugumante."

Elizabeth nodded.

Just when Zhang Jingyi and others were studying institutional construction.

Elf Village, Harbor!

A "joint craftsman team" consisting of a group of elf craftsmen and dwarf craftsmen are researching the "Zhang Jingyi warship".

In the naval battle with the Desert Kingdom, the flexibility and maneuverability of Zhang Jingyi's warships attracted the curiosity of the elven craftsmen.

The elves are a race full of wisdom, and one of the main reasons for their high wisdom is that they are full of curiosity and are always learning and exploring knowledge that they do not understand.

Be enthusiastic about learning so that your wisdom will always be online.

When you come across something magical like this, you naturally want to find out more about it.

At first they thought it was made by a dwarf, so they went to ask the dwarf craftsman. But the dwarf craftsman spread his hands and said, "We don't know how to do it! The core power of this ship is a magical machine that we don't understand."

Magical machinery?

Young man, you have successfully attracted the attention of the elves.

So, the elf craftsmen came in groups to clear the dungeon.

In the cabin of the ship where Zhang Jingyi was standing, a group of elf craftsmen and dwarf craftsmen were now surrounding the diesel engine.

"Is this its power core?" An elf craftsman touched the diesel engine with his hand, a puzzled look on his face: "What a fine craftsmanship! Look at its workmanship, it's so delicate."

The dwarves: "We are used to the fine workmanship of the things Mr. Zhang gave us. What is really hard to understand is the inner part." The Elf Craftsman: "What's wrong with the inner part?"

Dwarf: "Inside it, there is a burning chamber. The flame burns in the chamber, and the power it provides drives something called 'hydraulics' to operate... generating extremely powerful power."

At this point, the dwarf craftsmen also showed helpless expressions: "The spring power core we worked so hard to build is nothing in front of this magical machine called 'diesel engine'."

Elf Craftsman: "Its name is Diesel Engine?"

Dwarves: "Yes! Look, there are words written here. It is written in the language of the Eastern Rabbit Country... Marine diesel engines..."

The elf craftsmen nodded: "Diesel, is it the oil extracted from firewood?"

The enemies shook their heads desperately: "No! We should think of it as oil used as fuel like firewood."

Under the guidance of the dwarf craftsmen, the elven craftsmen quickly understood some basic logic of the internal combustion engine. However, they could only understand the basic logic. They could not understand the deeper level of technology. They only understood the general logic that the gas produced by combustion drives the machine to operate, but they could not see the details at all.

The dwarf craftsman said, "If we take this machine apart and copy it part by part, we may be able to make something exactly the same. Even every part can be made exactly the same. You can trust our hammer. But... we can't make these strange metals. They are always strange alloys. Also, we can't make this thing called diesel."

The elf craftsmen nodded: "Diesel is a big problem! Alloy is also a big problem. If we want to imitate such a machine, we need to solve the problems of materials and fuel in two directions."

The material problem is actually very difficult, but the elves always have a solution: "We may not need such excellent materials. As long as our pursuit of power is not so extreme, we can use inferior materials, but the output power will be weaker."

The dwarven craftsmen agreed with the elven craftsmen's idea: "We can use iron. Although it is not as good as alloy, it is only weak in output. But what about diesel? We have no way to deal with diesel that can burn inside the machine."

At this point, the dwarves showed a mysterious expression: "In fact, we secretly copied this machine without Mr. Zhang's knowledge, but we couldn't find a fuel that could burn inside. We tried coal, but it didn't work! We also tried grinding the coal into powder, but it didn't work either... They simply can't burn properly. Even if they finally burn, they will produce a lot of dust and slag, which will jam the machine."

"But what we can't do, you elves may be able to do."

The dwarf craftsman said, "You are better at using magic than us, and are good at using all kinds of strange magical materials. I think you might be able to find something that can burn internally."

When he said this, the elves fell into deep thought.

What can burn in a small space without producing waste and affecting the operation of the machine?
An old elf craftsman suddenly spoke up: "I have an idea."

Everyone turned to look at him.

The Elf Craftsman chuckled and said, "The Heart of the Mountain!"

"What? What is this?" The dwarf craftsmen were confused: "I have never heard of this term."

The old elf craftsman said: "The Heart of the Mountain is the heart of the mountain! It is a burning stone that has been burning in the mountain, forever. It does not require air to burn, and it does not produce any slag or dust."
