Copper ore?

Fiona frowned. If a large amount of copper ore was needed, I'm afraid this matter really needs to be discussed.

Most of the mines in the Irruth Empire are controlled by the four noble families in the imperial capital. Although copper mines are not magic metal mines and the amount of mining is very small, if you want to get a large amount of copper mines, those families are afraid that they will not be able to avoid it.

"Okay, this is indeed a problem. Let it go for the time being. I will ask Hilton and the others to pay attention to the news in this regard."

Fiona wrote down the tap water project, wrote the copper mine later, and then made a key mark to remind herself to pay attention to the news about this area at any time. Then she asked: "Did you forget anything other than this planning map?"

“Are you referring to mass production of air conditioners?”

Tang En's mouth curled up: "Of course I've thought of a solution."

"real!?"

Fiona stood up suddenly, looking surprised: "It can be mass-produced!?"

"That's right, but the consumption of demon dust is probably a bit large. Using the magic crystals that we Ellington now reserved now to prepare demon dust, I'm afraid it won't be able to create much."

"Even if you can't produce much, you can make a big profit while the weather has been very hot recently!"

Fiona is very positive about making money: "And we can take the high-end route and sell it directly to the nobles. An air conditioner costs at least 500... no, starting with a thousand gold coins!"

Fiona said viciously: "I'm sorry for this good opportunity if I don't make a big profit for them!"

Tang En laughed silently, pondered for a moment, and said to Fiona: "Leave this matter to me. I'll discuss with Brian and the others how to solve it, and there is no need to rebuild the factory. The blacksmith shop can be responsible for the production."

"real!?"

Fiona was stunned for a moment: "Is that air conditioner necessary to use magic? Is it possible?"

Fiona refers to the fact that Done hides his identity as a magician.

"I don't have to do it, I've solved this problem."

Tang En smiled, explained for a moment and left the lord's mansion.

After coming to Edgar's blacksmith shop, Don found that Brian was chatting and drinking beer with Edgar, while several apprentices were sweating profusely learning to smel ore.

Tang En raised his eyebrows: "Look at you guys are quite leisurely."

Brian's eyes lit up when he heard the sound and he jumped up suddenly: "Big brother! Is the steel mill completed? Can I start producing steel??"

This guy is really persistent in steel...

Tang En laughed silently: "Have you not been to see it these two days? You should know the progress better than me, right?"

"These two days are too hot... By the way, the air conditioner you made is such a good thing. I don't want to go out with this thing."

"So I stayed here and competed for the place with me at night?"

Edgar complained, and Brian glared fiercely, and Edgar immediately shut up. After all, he still has to learn skills from Brian. How dare he offend Brian?

"Do you like it?"

"certainly!"

Brian said without hesitation: "It can be said that this is the best thing you have made since I met you!"

"Oh? It's better than stamping machines and steel?"

"Well……"

Brian hesitated, and the blacksmith's instinct and the thought of enjoyment began to conflict fiercely.

Seeing Brian's uncertain appearance, Don't laughed: "Okay, don't be embarrassed. Look at you so leisurely, come and put some pressure on you."

"Lord, please give me orders."

Edgar is now obedient to Tang En. He has completely regarded his blacksmith shop as Tang En's possession. Not to mention anything else, hold the lord's thigh tightly and will definitely make a profit without losing money!

"What are you going to do?"

"Here, that's it."

Tang En pointed to the air conditioner and said with a smile: "Fiona decided to take advantage of the weather and starts to get hotter, so she plans to make a big profit. Hilton will come back to pick up goods in a few days. Are you confident that you can produce enough air conditioners?"

"ah?"

Brian was stunned: "How do we do this?"

The air conditioner was something that Tang En made. They didn't interfere at all. They didn't even know what the structure inside was. How to make it?

Brian felt that magic must be involved in it. He is not a rune dwarf and does not understand magic at all. How could he do it?

"Don't worry, the key problems have been solved for you. There are only two things you need to do."

Donn threw the drawings to Brian and said, "Just make the molds of these accessories according to the drawings, and then stamp them and assemble them."

"That's all?"

"And this one."

As soon as Tang En snapped his fingers, a circular plate appeared beside him.

"What's this?"

“Accessories for stamping hammers.”

Donn waved his hand, and then Brian and Edgar followed him to the next to the stamper. The stamper, cutting machine, and grinder are now Brian and Edgar's treasures. They are not allowed to touch the apprentices at all, and they are very clean.

Tang En embedded the circular plate at the bottom of the hammer, then pointed to the substrate on the drawing and said: "The most important thing is here. After embedding this circular plate on the hammer, adjust the height of the stamping machine, and then rush out the array diagram of the magic array on the substrate, then spread it with magic dust, and then stimulate it with magic crystal to assemble it."[e1]

Brian checked it carefully, suddenly stunned, and widened his eyes in horror: "Big brother! This is..."

Brian took a breath of air conditioning and looked at Tang En in shock: "Your method... is really feasible!?"

"Of course, I've tried it, it's totally feasible."

When Brian heard this, he was in a bad mood. He was circling around like crazy, muttering something in his mouth in dwarf language.

Tang En, who has mastered "very language", can understand what he is muttering, it is nothing more than "impossible", "how is this possible".

Suddenly, Brian stood still and stared at Tang En blankly: "Big brother, do you know what your invention means?"

"certainly."

Tang En nodded slightly: "I know very well."

"Then you are still so calm!"

Brian widened his eyes and waved his thick arms and shouted, "Did you know! This invention will change the whole world! This is not just for the production of air conditioners, its purpose, its potential is really terrifying!"

"Of course I know."

Tang En said calmly: "But so what? You just need to remember that it is only used to produce air conditioners now, do you know?"

Brian took a deep breath and calmed down. He understood what Tangen meant.

Brian said solemnly: "I understand, brother, my Brian Forging Hammer will remember your trust and guidance to me deeply. You will always be a friend of our dwarfs."

Tang En smiled slightly and said he had made a profit.

He did not forget Brian's identity. The immortal warhammer of the King of the Mountains is limited to the bloodline of the dwarf royal family. In other words, Brian has the bloodline of the dwarf royal family, and maybe he is the dwarf prince.

His promise is quite substantial.

"Leave this to us. If we use a stamping machine, we will make the template today and start production tomorrow. We should be able to make a lot of air conditioners before Hilton and the others come back."

"Okay, these bags of demon dust were temporarily ground by me before, so it should be enough for you to use it for a while."

Tang En handed over Demon Dust to Brian. He had already planned to go to Fort Caspami later. He didn't know how many medicinal materials Owen, the boss of Potion House, has collected these days.

Thinking of Fort Caspami, Donn suddenly remembered the carriage that tortured his butt for several days. He twitched his mouth and said to Brian: "By the way, there is another thing you can remember, you can study the intervals of producing air conditioners."

"What?"

Tang En took out a paper and pen and simply drew a spiral compression spring and spring sheet, and said, "This thing is called a spring, it is an energy accumulator that can be used to absorb shocks. You can try to use copper, iron and steel to make it better."

"Spring? Accumulator? Shock Absorbing?"

Brian scratched his head and asked, "Where is this thing intended to be used?"

"It's very wide-ranging, but at present, of course I plan to put it on a carriage."

Tang En sighed: "I don't want to torture my ass again when I travel."

Brian immediately understood the real function of this little thing and was immediately amazed.

What exactly is inside the big brother’s head?

Why can he always come up with such a wonderful idea?

"Pack it with me!"

Brian patted his chest and promised: "I will find a carriage to test it after it is done."

After discussing what happened afterwards with Brian and the others, Tang En left the blacksmith shop and returned to the lord's mansion. After briefly talking to Fiona, Tang En returned to his bedroom, and then he disappeared directly at the next moment, and then appeared in a remote corner of Caspami Fort.

After coming to Fort Caspami last time, he anchored the spatial coordinates here and could teleport over at any time in the future.

"It's just a teleportation technique, it shouldn't attract their attention, right?"

Tang En glanced at the sky, then turned around and walked out, heading straight to the Potion House.
