Rafa decided to put the steam engine at the mouth of the coal mine first, because it was very important to increase the productivity of the coal mine because all industrial activities in the city were inseparable from it, and the recent opening of cement factories and iron-smelting workshops had led to a sharp increase in the demand for coal, which is why he was tinkering with the steam engine.

The knights placed some huge steam engines at the mouth of the mine, then dug a small pit and fixed it to the ground with chains and stones.

"Your Highness, this is the guy you said could help us move things?" Andrew, the head of the mine, had just come out of the cave, covered in black coal dust, and could only tell by his eyes that it was still a person.

Looking at the pitch-black figure in front of him, Rafa frowned, "Andrew, didn't I make a mask for you? Why don't you wear it?"

"Uh... Your Highness... I wore it. Andrew removed a swarthy black cloth from his face, revealing the clean skin underneath, and he looked like he had drawn a line on his nose, black on the top and clean on the bottom, which he hadn't seen before probably because the color of the mask had blended in with his skin tone.

"Ahem, sorry. Rafa coughed twice in embarrassment, thinking that the protection measures for the workers needed to be further strengthened, "Have you finished arranging the new structure that I gave you to support the mine?"

"Your Highness, it was all done yesterday, and your method is really effective, after I put up the frame, sure enough, there were many fewer accidents of partial collapse, and the whole mine didn't seem to tremble much. ”

Andrew is a local, he followed his father into the mine since he was a child, until after the decline of the industry, he returned to the city to work as a blacksmith, until Rafa was recruiting experienced worker leaders, he felt that it was time to fight again, and volunteered to stand up, and Rafa did not pick, directly let him take the workers into the mine, it turned out that he did have some ability, not only the division of labor is clear, and there is no shelf as the leader, has been working with the workers in the cave, is a person who dares to do things.

Then Rafa called out all the workers in the cave and explained to them the function and simple principles of the thing, and although he did not expect them to understand, he just told them not to think that it was the power of the devil.

More than a hundred swarthy men surrounded him in the middle, and he felt a little funny, but he still stubbornly continued.

These new mine workers also have a good impression of this lord, not only let them eat three meals a day and have wages, but more importantly, this prince seems to have no shelf, and they seem to be flattered to hear such a big man talking to him at close range.

"Now, I'll show you how to do this," Rafa said to the lever and opened the combustion chamber, which still had unburned coal, "Andrew, dragging the chain down and tying the end to the frame where the coal was contained. ”

"Yes, Your Highness. ”

Andrew led a few men into the mine with thick chains, and Rafa began to order water to be poured into the steam engine.

In a few moments, the tailor-made chain was almost pulled to the end, and Andrew hurried out of the inclined mine with the men.

"I saw it all clearly. ”

With a shout, he began to personally swing the shovel and deliver the prepared refined coal to the combustion chamber.

The unknown knights and workers watched him closely, and when they saw him add coal to a burning fire, they all thought that this thing must be comfortable for a fire.

It's just that the strange noise of the next thing makes everyone stand up a little.

"Bang Bang Bang~~"

Rafa pressed the valve that represents the intake linkage.

The moaning of the steel gears rang out, like a mad bull preparing to rush forward.

"Bang dang!"

"Bang!"

The winch slowly spun around, and the loose chains on it were dragged up, and in the next moment they were stretched straight.

The sparks that burst from the chain made everyone present secretly frightened, and the strength of this thing seemed to be very great.

As the big guy continued to moan, the chains that had reached into the mine began to quickly lift up.

When people heard the "rumbling" sound of friction in the mine, some people even thought that a monster was about to rush out of the mine, and unconsciously retreated.

"Bang dang!"

The iron frame filled with coal, which was connected by chains, was suddenly pulled out, and the huge iron frame rubbed violent sparks on the ground with a terrifying sound.

"See clearly!"

Rafa then pressed the linkage valve, which represented the exhaust.

"Snort~~~"

The hot steam poured out, the turning winch stopped turning, and the iron frame pulled by the chains stayed in place.

Among the stunned crowd, Andrew was the first to react, "Oh my God! This big guy's strength is almost worth dozens of people!"

"Andrew, pick a few clever people to control this thing. ”

The people who were surprised by this force heard the conversation between the two, and then they got rid of their horror, and their eyes looked at the steam engine from indifference to curiosity and... Adore.

After explaining the principle to a few young men selected by Andrew, and then watching them take turns to operate and no problems, he went back with confidence.

On the way back, Audair asked with some curiosity, "Your Highness, that thing has obviously succeeded, why do you seem to be a little worried?"

"I was wondering how the rails should be made. ”

"Rails? What's that?"

Rafa glanced at her, "Don't you find it difficult to pull the iron frame directly from the rough ground with coal?"

"I don't see it, but I think that big guy is quite easy to do. ”

"It can be easier to do, and although it seems to be fine now, over time, the tunnels in the mine will be worn out sooner or later, and the ground is full of scattered coal dust, and there is no guarantee that if there is a spark and it will explode. ”

"Ahh ”

"So I'll have to ask that guy Barrow if there's anything he can do, and if he can't, I'll have to go to Elle. ”

Then he went to the iron-smelting workshop in the west of the city, where there were two simple milling machines that could do some simple rough work, such as iron sheets and nails.

At this moment an old man with a wrinkled face, a gray beard, and a heavy overalls was sitting in front of a milling machine, and he had two iron hinges in his hands, which he put together, and then threaded a small iron rod through the place where the two hinges met, and when he was sure that there was no problem with the opening and closing of the thing, he confidently threw the hinges into a frame full of hinges next to them.

"Old Barrow, didn't I let you work on those things from before, why do you keep clutching this hinge?" Rafa had told him about making parts for the steam engine, but he seemed to have a soft spot for the little hinge.

"Your Highness, you're here," Barrow was startled and hurriedly got down from his seat and saluted slightly.

"Answer my question. ”

"Uh... Your Highness, this thing called hinge is so delicate that I couldn't help it, so I made more... But rest assured, Your Highness, I have already memorized those things you explained, and I will definitely not make a mistake next time. ”

"It's good that I like to delve into it, but can you wait until I'm done with what I've been told?"

"Your Highness, I can only blame you for the elaborate hinge you designed... Besides, don't you want to build more houses in the future?

"Okay, okay," Rafa admired his character, but it was easy to forget his original task, if it weren't for the lack of manpower now, and his craftsmanship was not bad, he would definitely let him make his own drawings, "I didn't bring the drawings today, you just listen to me." ”

"Yes. ”

Rafa began to describe the small iron car that moved on the track, and the small iron car was not difficult to make, but the problem was that the steel rails that could carry such weight could not be easily replaced by other materials, and it was necessary to use 100 forged steel that could be squeezed by heavy objects and could not be deformed at all.

"Ahem, Your Highness, I understand what you mean, and it is really another extremely meaningful thing, if this thing can be created in the future, our transportation capacity will be greatly improved. ”

"It's up to you to say this, you just say if you can make it. Rafa admired his vision, but he always liked to talk about useless things.

Barrow looked around the entire workshop, "Your Highness, you see, although our workshop has a lot of manpower, as you know, it's good for us to make some simple iron tools, but it's really difficult for us to make such a long distance and not deform the hundred forged steel. ”

"Well, I see," he continued, as if he already knew the result, and continued, "You take your apprentices and hurry up to make two more sets of what I have given me, a total of four sets, and if they are done, five silver coins each." ”

"Yes, Your Highness. ”

Out of the hot iron-smelting workshop, he was ready to return to the City Lord's Mansion to continue to trouble Elle, his daily life is like this, wandering between the City Lord's Mansion, the west of the city, and the two mines of Okin Mountain, fortunately, Barov, Kono, Cole, Barrow, Andro and other people with management skills helped him share some of the affairs, otherwise he might not even have a chance to leave the City Lord's Mansion.

Among them, Audair was also assigned to the greenhouse area to do some simple management, although she did not reject such work, but she also had to perform the duties of Rafa's guardian knight, so she could only find time to come to the greenhouse area to make some simple arrangements.

But when Rafa was in public, she would never leave, and most of the work was left to a few female knights under the Order of Kono, who were now under the control of Audrey, so she sent them to manage the shed and arrange for some women's work.

Icefield City is now much more lively than ever, there are many women and children on the streets, and the men are always in a hurry, most of these women belong to the vegetable greenhouse, but they are not too busy with their usual work, except for spending most of their time tending to the crops, they prefer to come to the street in their spare time.

Thanks to the agreement signed with some merchants, many foreign merchants also came to ship the goods, and at the same time brought many foreign goods, which made the goods of Icefield City finally less monotonous, and finally began to become richer.

In short, the more people who come to Icefield City, the higher the development of Icefield City will be.

The current Icefield City is almost never closed during the day except for the night, so in order to prevent the invasion of the wolf cavalry, the realm work of the Knights is also very heavy, not only the work of the outer realm is taken care of by them, but they are also responsible for the security of the city, Rafa was worried that they would not be busy, but thanks to the careful arrangement of the head of Kono, the entire Knights operate in an orderly manner, not only does not have the slightest shortage of manpower, but even arranges for the knights to take turns off, it seems that he is familiar with the importance of each part of the entire Icefield City, and has done the most reasonable arrangement of manpower, and has played the greatest effect with the least manpower。

As he was about to return to the Lord's Mansion, a crowd on a nearby street caught his attention, and with the idea that it was human nature to be in the fun, he also led Audair towards the crowd.

The people around saw Rafa coming in person, and they all gave way to a passage.

When the crowd moved out of the way, he saw the scene in the field at a glance.

A woman fell to the ground, her broken red cloak with dark red marks, traces of blood.

But this is not the most surprising, the most amazing thing is that the blood flowing from her hand is actually burning with purple flames!

It's a witch!

Rafa was shocked, and knew that he must have found a treasure! However, if this treasure is not cured, it may become a dead treasure, and he must find a way to turn her into a living treasure.

But looking at the frightened eyes of the crowd around him, he knew that if he wanted to take her away, he might have to find a strange reason.

"Temple... Next, this woman, is a... Demon... Witch, right?"

Seeing Rafa coming, the bewildered people obviously had a backbone, and an old lady asked him in a trembling whisper.

Hearing the old aunt's inquiry, everyone present looked at him, and countless pairs of eyes with strange looks made him a little hairy.

Standing opposite him were the four Lena sisters, who had just come out to hang out, hiding behind several women, silently watching everything in the field, and they cared more about what Rafa would say next than ordinary people, because his words would determine the life and death of this woman on the ground.

After thinking about it for a long time, Rafa still couldn't think of any good excuses, but in the weird eyes of everyone, he still made a hard decision, "Ahem... This is just an ordinary woman, not a witch. ”

After saying these words, he quietly took a step forward, slightly releasing his spiritual power, and invisibly extinguished the purple flame.

Hearing Rafa's answer, many people were shocked, but the four Lena sisters breathed a sigh of relief.

"This woman is seriously injured and we need to treat her quickly. ”

Then, Rafa asked Audrey to carry the woman covered in blood, forced her to leave amid everyone's puzzled and strange eyes, and then fled back to the city lord's mansion.

"Your Highness, she's so hot!"

As soon as she entered the City Lord's Mansion, Audair immediately put her down, and then quickly took off her back armor, only to find that the thin armor had become charred as if it had been burned.

"Go and call Firi and Elle!"

Sending Audair away, Rafa reached out to probe her snort, and found that her snort was as hot as steam, and if it weren't for the strength of his flesh, he would have been burned.

After Rafa took the woman, the four Lena sisters also hurried back to their shed.

"Sister Lena, do you think that guy will hurt her?" Cole asked with some concern.

Lena pondered for a moment and replied, "I don't know, but since he hasn't declared her a witch, then she may have a chance to live." ”

"But she seems to be seriously injured, and she is a flame witch, I'm afraid ordinary people can't save her at all. Shirley was also a little worried.

Katya was always the calmest, "If that's the case, there's nothing we can do, although she can be considered our companion, but in order to save her, we have to expose ourselves, I don't agree to do this." ”

"Katya, do you want us to die?" called Shirley.

"If we could save ourselves, my answer would be yes. ”

In the end, it was the eldest sister Lena who stood up, "Don't say it, I'll go and see it tonight, if she really needs treatment, I'll find a way..."

"Lena—" Katya didn't understand why she was risking such a risk to save someone she didn't know.

"Don't be afraid, I'll be careful, I'll be back as soon as possible if that woman is okay. ”
