Zhou Feiyu has been in this world for three and a half years, to be precise, it is a month and two days, because most of the time is in amnesia.

Although Zhou Feiyu is now adopted by Ai Weijia, Zhou Feiyu knows that there is no free lunch in the world, and the person who brought him back is Ai Weid's brother Haku, and that person Zhou Feiyu has never seen him since he lived with Ai Wei.

Zhou Feiyu didn't understand that if he just picked up a child and gave it to the welfare home, why would he "throw" himself to his relatives. And in order to prevent that unknown idea, the first thing Zhou Feiyu has to do is the same, which is to talk about the "capital" of the conditions. ”

For this reason, Zhou Feiyu risked leaking Bluestar technology and came to a building, which is different from the ancient Western architecture, and the appearance of this building will make people mistakenly think that they have come to the era of the industrial revolution.

Huge chimneys, countless gears, and a plaque at the entrance reads big - Society of Mechanics.

Zhou Feiyu pushed open the door and walked in. As soon as you enter the door, there is a spacious hall, and there are not a few people in the hall, but it is far less than the previous bank, Zhou Feiyu shrugged his shoulders, and also understood, after all, although the mechanic is responsible for building equipment, but the combat style is called kite flow according to Zhou Feiyu's words, but here he becomes a coward.

Zhou Feiyu walked to the counter, and in the counter was a young man, 17 or 8 years old, who was stunned when he saw Zhou Feiyu, and then asked.

"Hello Miss, what's the matter? Is it to build equipment? If it's to build equipment, there are different prices, ah, if you provide materials, we will discount them appropriately." ”

Zhou Feiyu thought for a while and said, "I want to borrow a workshop, how much does it cost." ”

The young man was stunned and said, "Ah, I'm sorry, our workshop here is not open to the public, so miss, you are a mechanic?" ”

Zhou Feiyu immediately made up a reason: "Ah, that's the case, I'm very interested in this aspect." How long will it take to use the workshop if I become a member of yours?"

The young man waved his hand: "No, as long as you are a mechanic professional, you can join the association and rent a workshop." ”

Zhou Feiyu nodded and asked, "How can I prove that I am not a mechanic?"

The young man heard Zhou Feiyu's words and took out a form: "The mechanic is the most special of all the professions, being a mechanic doesn't need too much mana, the most important thing is the understanding of machinery, as long as you can use mana, you can become an apprentice mechanic immediately after signing up." ”

Zhou Feiyu felt a little big, did he still want to become a member of the Mechanics Association? The more open organizations he joined, the easier it was to be exposed, although he didn't know who he was exposed to, and even the enemy was not sure, but if someone who had a conflict of interest with him wanted to check it in the future····· Wait a minute.

"To put it another way, my level of knowledge is far beyond that of this civilization, and if I don't easily show some technology that is completely incomprehensible, then others will misjudge my strength, so that when a competitor makes a move on me, I can turn him in turn. ”

"I joined. Zhou Feiyu didn't say a word, picked up the form and filled it out. In less than a minute, Zhou Feiyu filled out his own form.

The young man put away the form, smiled and took out a card, which was very similar to the card he had made in Owen's territory before.

"This is your Mana record card, this can't be copied, you inject Mana into it and you can record your signs, and we'll record it in the database. ”

Zhou Feiyu nodded, Zhou Feiyu actually already knew what Mana was, when Owen killed the bandits before, Zhou Feiyu asked Yuyin to solve Mana, and this has been more than three years, after countless calculations and checks, it came to the conclusion that Mana is magic. And we generally call it - dark energy.

Dark energy is a type of energy that drives the movement of the universe. Neither it nor dark matter can absorb, reflect, or radiate light, so Zhou Feiyu cannot observe it with the naked eye.

Because the people here are in the flow of biological evolution, they have been able to reach the level of spiritual exploration, and they have discovered dark matter first.

Zhou Feiyu manipulated Yuyin to control a part of the original canonical particles to form a trace amount of dark energy, which recorded his body information, and came into contact with the card, and the dark energy was absorbed by the card after touching the card.

"Okay, in that case, it's documented, since you're new to the association, you're a 'mechanic's apprentice' for the time being, you can go through all the materials, and I'll find you a mentor to visit the building association later. Is that okay?"

"Okay. ”

The young people picked up the communication stone and began to make contact.

Zhou Feiyu began to think about a question at this time, that is, what stage is the scientific and technological level of this world in, it seems okay in terms of organs, but it is not almost, or 0 in virtual engineering, and lacks relevant theoretical knowledge and cognition of the microscopic world.

Just as Zhou Feiyu was still thinking about it, there was a commotion suddenly upstairs. Zhou Feiyu turned his head to look in the direction of the stairs, and a group of people rushed towards Zhou Feiyu like a group of zombies.

"It's really! God is really an eye-opener! It's really a lady! There really is a lady who wants to join the Machinery Association! Come and be my apprentice! I'll teach you all the housekeeping skills!"

"You old rascal! Don't pee to see what virtues you have, a level 4 mechanic also wants to take in apprentices? Madame come to me, I'm a level 6 professional! I'll teach you everything I know!"

Zhou Feiyu looked at the young man in front of him, and the young man looked at Zhou Feiyu.

The young man smiled eerily.

"No, it won't. ”

"Well, it's the first time we've had a lady from the Mechanics Guild attend, and I just told all the instructors with the Communication Stone, and I'm a little sorry for you but you can't run away. ”

How to run? TMD, a bunch of level 6 professionals in the mechanic association, take the head to run! However, the people who came to Zhou Feiyu were not as frantic as they were on the stairs, but they were all quite gentlemanly, but before they could say a word, they were kicked away by the people behind them.

Just as everyone was in a mess, a loud voice calmed everyone.

"What's the noise, haven't you seen a woman?" his voice did not hide his anger. After hearing this voice, the scrambling mechanics stopped making a fuss, and a middle-aged man, about forty or fifty years old, walked down from the upper floor.

The young man was wearing a white coat, and if that could be called a white coat, the various charred marks on it looked like a tie-dyed garment.

"It will grow well. "Good for the president. ”

The president glanced at Zhou Feiyu: "Follow me." ”

Zhou Feiyu took a deep breath and bowed.

Following the president, although the chairman didn't seem to have a good temper, he still carefully explained to Zhou Feiyu what the facilities here were for.

Zhou Feiyu suddenly remembered something after the president, and said a string of demonic numbers.

That's the answer you're looking for. ”

The president stopped suddenly.

"Wait a minute! Five minutes, just five minutes. ”

The young man rushed to his laboratory, and only five minutes later, the person in the room with a loud bang was a little deaf, and the young man rushed in front of Zhou Feiyu at the speed of a 100-meter sprint, and his attitude was already a 180-degree reversal.

Zhou Feiyu smiled and secretly said in his heart: "Learn mathematics, physics and chemistry well, and you will not be afraid to go all over the world." ”

The middle-aged man couldn't help but pull Zhou Feiyu to the second floor, and in the largest workshop on the second floor, Zhou Feiyu saw what he was thinking - black powder.

Black powder should have been "invented" a long time ago, but why was this civilization invented at this moment? That's because there are alternatives, just like if you know how to use fire magic, you can make fire directly, then the relative fire tools, lighters, matches, etc., will not be invented, because there is no need.

The middle-aged man found a chair for Zhou Feiyu and couldn't wait to ask.

"How did you know I was doing this experiment? What level of professional are you? You can't be a spy, are you? ······"

"Stop, sir, stop. First of all, I think it's time to swap names before we get into it, I'm Ryan Hill, and I'm the adopted daughter of Add's family. ”

"Oh, it's me who is rude, my name is Yu Wenheng, and I am the president of the Mechanics Association. ”

"Well, so I'll tell you how you know you're working on this "black powder". ”

"Oh, this thing is called black powder, has anyone invented it before me?"

Zhou Feiyu nodded and said I want to ask a question, do you have faith?

Yu Wenheng thought for a while and said, "It's okay, I'm not very religious. ”

Zhou Feiyu thought for a while, if the belief is not very pious, then it should be no problem to reveal a little bit about the first-level civilization.

"I told you that I was an adopted daughter, but why did I become an adopted daughter, do you want to know? This may upend your beliefs, and even the world you know, because this is our family secret. ”

Yu Wenheng thought for a while and said without hesitation: "No, although I am very interested in the secret you have, I can probably guess why you became an adopted daughter, this secret may endanger you, it is best not to tell it." ”

This was greatly unexpected by Zhou Feiyu, he thought that Yu Wenheng would immediately express his willingness to listen to his "secret", but he didn't expect him to refuse completely.

"Okay, then I'll answer your question head-on, I'm a second-level professional, why would I know that you are making black powder First of all, you are wearing a white coat, your cuffs have black powder, and your clothes have a little bit of scorching marks, and the flame traces are unique to explosions, so I guessed about it, black powder. ”

"I see, so what is the purpose of your here? you have your family heritage, and you certainly don't see things the same way we do. ”

"Weapons, I personally gave myself tailor-made weapons. Zhou Feiyu made it clear what he meant.

"Well, that means you need a workshop, this is simple, I'll help you solve it, a dedicated workshop, by the way, did you go to school?"

Zhou Feiyu was puzzled for a moment, but he didn't take it to heart.

"Nope. ”

"Well, if I can, I can introduce you to a school, and by the way, what you need in your workplace can be brought up to me directly. ”

Zhou Feiyu thought for a while and said: "An ordinary set is fine, ah, it would be better if there was a carved gold platform." ”

"Hmm····· , no problem, are you in a hurry to use it now?"

"No hurry, ah, by the way, if you can please prepare these materials for me. ”

Zhou Feiyu asked for a piece of paper and wrote some materials.

"How many metals can be smelted at the same time in the largest furnace here? Zhou Feiyu asked casually

Yu Wenheng thought for a while and said, "You can probably smelt about 10 tons of mana iron, what do you want to do?"

"I'd like to borrow it for tomorrow afternoon, and it would be nice if I could find four or five people to come and help me. ”

“······ Are you sure you're forging weapons? It's a ton-based furnace. ”

"I'm pretty sure, then that's it, it's not too early, and I should go back too. Ah yes, by the way, put the black powder into the steel pipe on the back cover and then make the wire exposed to the outside is a detonator, the diameter is not recommended to exceed three centimeters, the length is not more than 20 centimeters, at least to ensure that there is no one within 100 meters around. ”
