"Wow, this thing is really hard. I'm afraid there's no way to cut it off without some tricks!"

In the "forbidden zone" where the Eternal Furnace was located, Carl dropped the tools in his hands and sat down on the cloud that was as hard as iron and stone.

Beside him, Nia had already set up her experimental equipment and was studying the composition of "cloud iron".

"This thing looks like some kind of aerogel, but how did this strange difference in softness and hardness come about?"

After a simple test of Yuntie, Nia looked at the changes in the solution in the test tube and gave her own judgment.

Carl, who was standing by, knocked on a larger piece of Yuntie, and a "dong dong" sound was heard.

“Let’s not worry about those profound parts for now, let’s first study whether there is any suitable way to mine this thing.

If its properties are stable, I think it could be used to make something.”

Carl took the softer cloud handed to him by Hope, pressed it twice, and then leaned on the cloud, feeling very comfortable.

Farther away, Ying, Iris and others were lying on a large piece of soft cloud, as if they were treating it as a big bed.

After hearing Carl's suggestion, Nia took out several solutions and poured them into the test tube containing yun iron.

After a while, she frowned and said in a somewhat incredible tone: "You can shape it by smelting metal, but you have to pay attention to the ratio of it to the air element. The air element seems to be like carbon and iron to it."

Hearing this, Karl also showed an incredible expression on his face.

Although nature is very magical, this is too magical! However, thinking that this seems to be the area where the Eternal Furnace is located, Carl was relieved again.

Maybe this thing was shaped by the energy radiated from the Eternal Furnace. After all, according to the theory of the School of Change, when the boundary between energy and matter is broken, the chaotic matter that is born can produce things with any kind of characteristics.

"Hmm~, according to what you said, could it be that those soft clouds have a special content of air element?"

Pulling out the cloud that he was leaning against behind him, Carl tore off a piece, and then called the iron ants running around on the cloud.

Iron Ant quickly replaced the rune cartridge with a fire arrow, and then heated the cloud that Carl tore off.

After a while, some water vapor came out from it, and the cloud, which was originally very soft, became as hard as iron again.

"Ha! So it's related to the water element, so these clouds are actually rust?"

Using his psychic power to control the hardened piece of cloud iron back into his hand, Carl picked up the fragment and looked at it towards a brighter spot.

This cloud iron is not light-transmissive. Even if it is just a small piece, it will not let any light pass through.

Carl tossed the fragments up and down in his palm several times, weighing this strange substance and already had some ideas in his mind.

"I feel like this thing can be used to build spaceships! It has good hardness and toughness, and is very light."

Thinking of this, Karl simply stood up and moved the Yun iron he had just excavated to the machine tool for processing.

The iron ants seemed to be inspired, so they replaced their rune cartridges and tried to use water manipulation to help with mining.

However, although removing the water element only requires simple heating, injecting the water element into the cloud iron has become a somewhat difficult operation.

The three iron ants worked for a long time, but they only made the surface of a part of the cloud iron slightly softer.

With this time, they can pick up their pickaxes and dig more!

"Alright! Take these drills and use them. Be careful not to hurt yourself."

Seeing that the iron ants seemed a little frustrated, Carl had to give his spare electric drill to them, while he concentrated on processing the cloud iron.

Carl had already had a rough idea of ​​the structure of the spacecraft before he set out for Dalcate, and now he was just reproducing the idea in his mind.

But this is also thanks to the memory talent brought by his own dream world, otherwise Carl would not be able to remember so many structures.

The "ding-dong" knocking sounds continued for several hours, and gradually, some basic structures were built by Carl.

When Nia came back to her senses from the alchemy experiment, she found that there were fewer clouds around her than before. When she looked up again, she saw the spaceship parts made by Carl.

"How big a spaceship are you going to make? This size... I'm afraid it must be several times bigger than that bronze-wood warship. The little cloud iron we have now is not enough to build it!"

Seeing that Carl seemed to be continuing to make it, Nia hurried forward to stop him.

"It's okay! I'm planning to build the spaceship in sections. I made a rough estimate and found that if I only want to build a small part of the spaceship, these cloud irons will be enough.

As long as it can fit the truck in, it will be much easier later on.”

As he spoke, Carl took out the blueprint from his dimensional bag and showed it to Nia.

Although Nia's talent in mechanical design was not as great as her talent in the way of magic, she still roughly understood Carl's drawings.

"You actually plan to temporarily use the mecha as the driving part of this spaceship?"

Looking at the spaceship composed of multiple machines on the blueprint, Nia frowned with a look of disbelief.

Nia always thought that this was Carl's trick to get those kids to collect all the mechanical dolls!

I didn't expect that he would actually plan to realize this idea today!

Although Nia's talent for mechanical design was not high, she instinctively felt that this approach was unreliable.

Looking down at Nia, Karl said seriously: "Don't worry, it's okay! I will definitely complete this design!"

Nia had a thousand ideas to complain about this design in her mind, but after looking into Carl's eyes, Nia retreated shamefully.

Because she found that there was a light flashing in Carl's eyes.

"This is just one time, never again! Don't try to replicate this unsafe design in the future!"

Nia turned around with a rosy face, put away her experimental equipment, and then followed everyone back to the truck.

As the structure of the spacecraft built by Carl gradually improved, there were fewer and fewer clouds for them to land on.

However, Carl was considerate enough to let everyone take many soft clouds back to the truck. After all, these things were much more comfortable than the original seats.

With the help of the iron ants, a white device similar to a thruster was soon combined with the truck.

Carl and others got back into the truck and headed forward again.

But this time, they were observing the situation around them with purpose, trying to find more cloud iron and use it as building material for the spacecraft.

…

“Ding! Ding! Ding!”

On a huge cloud mountain made of cloud iron, Tina was holding an iron pickaxe and digging the cloud iron.

After being introduced by an acquaintance, she joined the mining group and became one of them.

"As long as I have twelve more cubic meters, I can try to build an airplane! Wow, why is it so difficult to mine this Yun iron? Can't we use explosives or something like that?"

With tears in her eyes, Tina hammered at the hard cloud again and again.

This was already her third day in the mining group, but after deducting what she needed to hand in, she had only collected two cubic meters of cloud iron.

Hearing her complaint, a miner nearby laughed and said, "You are really impatient, but I advise you to put aside that dangerous idea. Natural ferromagnetic iron is already very hard, but if it is hit by an explosion, the fire element will change it similar to quenching. It will be even more difficult to mine it then."

Hearing this, Tina took two steps back and sat on the cloud.

"Ah~, no wonder everyone on the floating island would rather spend money to buy it than come here to mine it themselves. I still need 12 cubic meters of cloud iron to mine. How long do I have to wait~"

Tina leaned aside with a sad face, feeling as if she had become depressed.

"So why are you so anxious? If you want to go out and take risks, you've waited so long, can it be that you have to wait for a few days? You need to be calm, otherwise if you encounter problems in the future, you might mess yourself up."

Like a wise man who has seen through life, the miner uncle next to him waved his pickaxe seriously and collected the broken pieces of Yuntie bit by bit.

Putting away the expression on her face, Tina quickly got into the state and started working hard.

A few hours later, the mining group prepared to return to the island to rest, and Tina followed them and took the teleportation array back to the floating island.

After handing over part of the Yuntie as the fee for using the magic circle, Tina took the remaining Yuntie back to her home.

Instead of falling asleep as usual, she took out the design drawings from her backpack and walked into the basement with Yuntie.

"Although there are still many missing materials, I can complete the construction in sections! Let's build the glider of the plane first!"

Comparing the ratio between the drawing and reality, Tina raised the furnace and prepared to smelt the cloud iron.

As the descendants of mages, everything on this floating island is more inclined towards magic.

The reason why a mechanic like Tina appeared was because someone broke the ancestral magic device. In order to facilitate future repairs, the village chief returned to the main plane and spent money to buy teaching materials to train her.

However, Tina's teaching materials were already hundreds of years old, so although she had the idea of ​​using strange devices to go on adventures, she was still limited by her own knowledge and only designed a glider.

Referring to the drawing, Tina poured the liquid iron that had been melted into a flaming cloud into the mold that had been prepared in advance.

When the temperature dropped slightly, she used her hands wearing dragon skin gloves to disassemble the clay mold.

The cloud iron, which was changing from fiery red to pure white, emerged from it. Taking advantage of this opportunity, Tina lifted it onto the anvil and started hitting it with a small hammer.

There were some tinkling sounds, but because the house was well soundproofed, the neighbors did not come to accuse her of disturbing the public.
