After sending the last deceived person away, Xu Yi let out a long breath and stretched.

"Whew, it's finally done, I'm exhausted. ”

Heinze just handed Xu Yi a cup of warm tea, and said with a smile: "Actually, since you expected today's situation, you should have called those students too, if you are alone, of course you will be tired." ”

Xu Yi shook his head: "That's not good, their studies in the academy are very important to them, and I can't delay them." Besides, the contract signed with them at that time made it clear that it could not conflict with their class time. Besides, the production of magic fans is also closely related to them, in case they are tired, it will not affect the production. ”

Heinze glanced at Xu Yi: "Are you tired?"

"Hey, this little bit of strength is nothing, I used to ......" Xu Yi suddenly paused.

He originally wanted to say that when he was tackling a key topic in the research institute before, he once tried to sleep only four hours for three consecutive days. Compared to then, this is not a small amount now.

However, he immediately reacted that he was no longer in the original world, and he was afraid that he would never be able to return to the frenzied research atmosphere he had before.

Thinking of this, Xu Yi couldn't help but feel a trace of melancholy in his heart.

Seeing that Xu Yi suddenly became silent, and the expression on his face was a little dazed, Heince was a little confused, but he also knew that it was inconvenient to ask more, so he also fell silent.

For a moment, all that was left of the room was the sound of Alex packing up.

After a long while, Xu Yi suddenly shook his head vigorously and smiled at Heinze.

"I'm sorry, I'm distracted. By the way, where did I just go?"

"You said that you can't exhaust those students and affect production. ”

"Oh, yes. Speaking of which, Heinze, you should take the time to make another trip to Baron Ricto's Academy of Magic, and it would be better to recruit some more students. Or you can ask the students who have been hired to go back and help spread the word, and the effect may be better. I'm about to develop the second version of the Magic Fan, and maybe I'll start production at the end of this month, and I'm going to need a lot of manpower by then. ”

"yes, I see. Heinze casually recorded what Xu Yi said in the small notebook he carried with him.

Seeing his actions, Xu Yi couldn't help laughing, because Heinze's action was like a competent secretary.

Heinze was a little inexplicable by Xu Yi's laughter, but as soon as he opened the book, he remembered another thing. "By the way, Xu Yi, I asked, there is really nothing like a newspaper like the one you said in Bangta City. The closest thing is probably the newspaper sent out by the City Lord's Mansion every once in a while. However, that thing was only issued to the noble grandfathers in the city, and ordinary people couldn't see it at all. ”

"Well, forget it, I'll think of another way to advertise. Xu Yi waved his hand and signaled that this matter should be put down first. "Speaking of manpower, Heinze, I think we should hire a group of blacksmiths directly. ”

"Huh?" Heinze was stunned by Xu Yi's leapfrog thinking. "Hire a blacksmith? Why? If it's for forging fan housings, wouldn't it be better to give it to a blacksmith shop in the city?"

"That's too restrictive. If something goes wrong with the blacksmith shop in the city, it's hard for us to deal with it properly. Xu also shook his head in denial. "Of course, the most important thing is that we need professional people. In fact, I have always been dissatisfied with the fan housings made by these blacksmith shops in the city, and the quality does not meet my requirements, and I have been using them because I can't find a replacement for the time being. After today's events, haven't you noticed that the reason why we have lightly convinced those people that the magic fans they buy are not from us, is because the quality of the magic fans we produce is better? Therefore, if you want to ensure the value of a brand, you must ensure the quality. ”

Heinze thought about what happened today and found that Xu Yi was right.

If it weren't for the obvious gap in quality, which made those people have to admit that the magic fan they bought is not the same thing as the new flying brand magic fan, I'm afraid this matter would not be so easy to end.

"But where are we going to find a good number of suitable blacksmiths?" Heinze frowned.

"Actually, we don't have to be particularly skilled, but we need specialized, suitable blacksmiths. Do you know what I mean?" asked Xu Yi.

"What do you mean...... We just need to hire some blacksmiths who know a little bit about forging fan housings for us?"

"Yes, that's what it means. Even ......" Xu Yi smiled slightly, a strange light flashing in his eyes. "Later, it has developed to a certain extent, and even these specialized blacksmiths can not need much. ”

It was already afternoon when he left Heinze's grocery store, Xu Yi looked up at the sky, and thought to himself that he had taken another day off today, and he had already taken three days off this week, and he hadn't worked at the magic tower for nearly half of the time.

"Colleagues in the lab must already be guessing that I don't want to do it, right? Maybe they might say that I was too stupid to give up the opportunity to study magic with Grand Magician Camilla. Xu Yi smiled self-deprecatingly. "But speaking of which, Grand Magician Camilla has never expressed his position, and if it were someone else, he might have been kicked out of the magic tower. ”

While guessing the true attitude of Grand Magician Camilla, Xu Yi walked briskly around several street corners and came to the volcano blacksmith shop again.

As usual, as soon as I walked into the blacksmith shop, I was greeted by a wave of heat.

"Hey, Master Lanu, come on. Xu Yi didn't even look at it, and threw the wine bottle in his hand into the blacksmith shop.

A thick arm reached out from the heat and caught the bottle steadily.

"Stinky boy, don't you see me working......? Huh, good wine!"

As soon as Master Lanu cursed, he was attracted by the strong aroma of wine from the bottle, and without saying a word, he poured a large sip into his mouth.

"Whew...... It's really good wine!" Master Lanu spat out a mouthful of wine in satisfaction, and by the way, he also burped a wine before looking at Xu Yi. "Hey, boy, this should be the thirty year old of Thatch Manor, right? This bottle will cost five gold coins at least. You kid won't be okay with affection, let's say, what's the weird request?"

"What do you mean by strange requests?" Xu Yi said, "Master Lanu, have you always been dissatisfied with the requests I made before?" Don't forget that you yourself agreed, after changing according to my requests, will the effect of those two machines become much better?"

"Hmph! I said so, but you kid is going to toss me up every time you ask for it. ”

Xu Yigan laughed twice, looked to the side, and his eyes fell on the two strangely shaped machines placed in the corner of the blacksmith shop.

"Wow, Master Lanu, I haven't been here for two days, and you're done?"

Xu Yi rushed over excitedly, and made a few laps around the two machines, with an expression like seeing a baby.

"Hmph, who is my Lanu? It's just two machines, what's the difficulty?" Master Lanu snorted coldly and poured another sip of wine.

At this time, Xu Yi had already begun to carefully inspect the two machines from head to toe.

One of them is naturally the magic tooth rubbing machine that he found Master Lanu to help him make zuò some time ago, and the other is the magic head machine that was added later.

These two machines are important machines for making screws, and as long as they can operate successfully, the mass production of screws envisioned by Xu Yi will become a reality.

Don't underestimate screws, this thing looks inconspicuous, but it can be found everywhere in industrial systems and is almost one of the essential materials.

Whether the earth is big or small, complex or simple, no matter what industrial machinery or industrial products, there will almost always be screws in it.

Being able to successfully mass-produce screws means that Xu Yi has finally taken a solid step on the industrial road of Sainz Continent!

"Master Lanu, can these two machines be used now?" Xu Yi turned his head and asked.

"Nonsense, I'm done with you, can't you use it yet?"

"Good. Xu Yi picked up a small iron pillar in the blacksmith shop, put it in the mold of the heading machine, and then pressed the switch of the header.

There was no movement.

"Fool, you didn't put the magic crystal in, how could you move!" Master Lanu roared behind him.

Xu Yi patted his head, only to realize that he was so excited that he had forgotten the most important thing.

Xu Yi hurriedly took out a high-grade crystal that had been prepared a long time ago and put it into the power source of the header, and pressed the switch again.

The punch inside the header suddenly made a "bang" sound, and the entire punch flew out at high speed and hit the top of the iron pillar in the mold.

"K-"

There was a crisp and slightly weird loud noise in the header, which caused the header to tremble violently, and the ground of the entire blacksmith shop also shook a few times with this loud noise, and the momentum was really terrifying.

Xu Yi couldn't help but be stunned.

Isn't it just a screwhead, as for making it so earth-shattering?

It took him a moment to react, and he pressed the control switch again, and the punch was back to the top.

Xu Yi took out the iron pillar in the mold, and was pleased to find that one end of the iron pillar was indeed extruded into a round head under the huge pressure of the punch, and there was a cross-shaped groove at the top end, which was a standard screw head.

"Not bad. Xu Yi nodded with satisfaction. "Try the Tooth Rub again. ”

Compared with a simple and crude heading machine, the operation of a tooth rubbing machine is much more complicated.

Although Xu Yi had already made many simplifications, there were still as many as four magic arrays used on this magic machine, and the drawing of the magic arrays alone consumed a lot of Xu Yi's energy, not to mention the perfect integration of these four magic arrays with the entire machine.

However, when watching the screws quickly carve a circle of threads under the cutting of the tool, Xu Yi completely forgot the hard work of researching this machine, and was full of a sense of accomplishment.

This is in the continent of Sainz! This is a world with no industrial base!

To be able to successfully make a screw in this world is a great achievement!

As the most important participant in the completion of this great project, Xu has every reason to be proud!

Lanu on the side watched an ordinary iron pillar turn into a delicate and beautiful screw after a moment of processing by the two machines, and his heart was also full of surprise.

At first, he just thought that the two machines designed by this kid were very strange, so Lanu helped him make them with a challenge.

And now seeing the magic of these two machines, Lanu suddenly felt that these two machines were more important than any iron tools he had built before.

"How the hell did this kid come up with these two machines?" Lanu looked at Xu Yi with curiosity in his eyes.
