Coming out of the city lord's mansion, McGonagall went to the factory in the north of the city non-stop.

All the machines have been assembled according to his requirements, and the steam spinning machines stand in the empty workshop, although the shape is simple and shabby compared with modern machines, but in this world it is the second combination of steel and steam engine, which has epoch-making significance.

McGonagall was sure that the machines could do the spinning task and were more than 100 times more efficient than the average female weaver.

However, because they don't know how to use these machines, the Night Elves have no choice but to leave them idle, and are currently practicing archery and magic under the leadership of the head of the guard, Ashley.

McGonagall found Ashley, the head of the guard who looked quite strong compared to the slender body of ordinary elves, one of Irina's most trusted elves, and was also responsible for restraining the behavior of the Night Elves and training the existence of the Night Elves when Irina was in charge.

"Mr. McGonagall, is there anything wrong?" Ashley looked at McGonagall and asked, she had always had a lot of respect for the human who had helped the Night Elves so much.

McGonagall smiled, "That's right, I'm here today to teach you how to use the factory's machines, how to use the machines to spin efficiently, and get the factory up and running." ”

"Wait a minute, I'll go gather all the Night Elves." Ashley turned to leave.

"Wait." McGonagall hurriedly stopped her, took two steps forward, shook her head, and said, "I don't need to gather everyone first, because the restaurant is busy, so I want to select ten elves from the night elves with quick hands and feet and good memory to teach them in small classes, and after they learn, they will teach other elves." ”

"Okay, then Mr. McGonagall wait a minute, I'll go find the ten elves." Hearing this, Ashley nodded, turned around and walked away quickly, bringing ten elves with him not long after.

McGonagall looked at those elves, five men and five women, all of whom were above level six, and they could be regarded as the most powerful existence among the night elves in the factory, after all, the strength of these night elves in the factory was generally low.

"Mr. McGonagall, do you think they're qualified?" Ashley asked.

"Of course, please come with me." McGonagall nodded hurriedly, joking, but it's just spinning a yarn, if you can't even a group of sixth- or seventh-level elves, then the requirements for textile women are too high, right?

McGonagall led everyone into the production workshop, first went to the boiler room, and gave a brief introduction to the steam boiler and the operation principle of the steam engine driven by it.

"Excuse me, can we set those steel monsters outside in motion if we burn a fire here?" A female elf asked curiously, they had just seen how huge those machines were.

"Yes, that's the wonder of the steam engine." McGonagall smiled and nodded, but she didn't explain too much science to the group of magicians, determined that the three male elves were in charge of burning the boiler, taught them how to operate the boiler, and handed out a boiler manual, and then took the rest of the elves to the production workshop.

McGonagall was like a teacher, explaining to the elves how to use a loom to turn clumps of cotton into complete pieces of cotton.

Feeling the surprised and adoring gazes, McGonagall remained silent on her face, but she was a little proud in her heart.

Although he stood on the shoulders of giants, it also showed that he had not returned all the things he had learned to the teacher.

"That's probably the way the operation and explanation, I believe everyone has memorized it, but if you want to become a qualified textile worker, you still need to continue to hone on the assembly line." McGonagall looked at the elves and smiled, "So, let's start a formal operation." ”

Although the elves were surprised that McGonagall had let them get started so quickly, they hurriedly returned to their respective positions according to the previous arrangement.

"Youlao, let the boiler room start boiling." McGonagall said as she looked at one of the elves in charge.

The elf walked away quickly, and soon black smoke rose from the chimney of the boiler room, and steam poured into the workshop along the pipes, into the cylinder of the textile machine, accompanied by the clatter of gears, the steam spinning machine began to move, and the cotton wool put into the spinning machine entrance was swallowed by the machine*** dense and complex machine moved back and forth, and one by one fine cotton yarns began to appear, automatically wound on the coil, and soon it was full of a coil.

The elves present watched this scene with wide eyes, and after a while, the elves reacted, stepped forward to take off the coils that had been wound, and wrapped the cotton yarn around another wooden support.

"Oh, what an incredible thing, as long as you throw the cotton wool into that opening, this machine will really spit out the cotton yarn by itself, and it is more delicate and soft than the cotton yarn spun by ordinary female workers!" An elf pulled out a cotton yarn and couldn't help but exclaim.

"Yes, this kind of cotton yarn can weave a very good cloth, and it should be able to sell at a very good price, right?"

"The most terrible thing is this kind of textile efficiency, even the most skilled weaver, the speed is less than one percent of this machine, and it doesn't require us to do too much work, just put in the cotton wool, and after the coil is wrapped, change the coil."

The elves were talking a lot, and during this time they were still thinking about what these steel blocks in the factory were used for, but now after seeing these big guys move, they actually spun cotton yarn that was even more delicate than that of the female workers, and all the doubts of the elves were dispelled, and now only the worship of McGonagall remained.

What kind of fairy machine is this!

With it, wouldn't those women textile workers be unemployed?

McGonagall also picked up a roll of cotton yarn and looked at it, the quality of the cotton yarn is indeed good, the thickness is uniform, the texture is soft, and it can be seen that the stability of the machine is good.

Looking at the rolls of cotton yarn that were formed with the throughput of the machine, McGonagall suddenly realized that the birth of these cotton yarns could have a devastating impact on the textile industry in this world.

The world is still in a state of primitive inefficiency in spinning a single cotton yarn, and the steam spinning machine is equivalent to jumping forward two big steps, leaving the whole world behind.

"At the same time as the production efficiency is improved, the labor cost has dropped sharply, which will have a subversive impact on an industry, and for that impeccable empire, it seems that there is a good dagger that can be stabbed." McGonagall thought for a moment, a smile tugging at the corner of her mouth.

The Los Empire is a big spinning country, seventy percent of the world's cotton yarn is produced in the Los Empire, and the landlords who control countless female textile workers have accumulated a huge amount of wealth by relying on this.
