i became a fairy

Mi Xiaoan was able to come up with solutions to the three worries that Richard raised in his letter. Moreover, the casting method mentioned in the letter also solved another problem that worried her.

stability.

The previous frame was built by hand, and it was necessary to rely on iron drills to nail the steel pipes together one by one. In this way, the stability was inevitably not guaranteed.

Now that the dwarves have figured out the casting method, they can naturally apply it to the frame, and the entire frame can be cast.

Of course, the unilateral strength of the cast frame will probably be worse than that of the previous one. But in terms of overall stability, there will definitely be a huge improvement. At least when I ride it again, I won't make such squeaking noises anymore.

Moreover, as long as the grinding machine is designed to polish the body, the beauty will definitely not be worse than that of a forged frame.

All the problems were solved in Mi Xiaoan's mind, and she couldn't help but show a look of satisfaction on her face. Seeing this, Alela hesitated a little and asked tentatively: "How about An? What about the problem that Riward mentioned? Can it be solved?”

She had read the letter and knew its contents.

"Ha, yes." Mi Xiaoan nodded affirmatively and said, "Uncle Richard and the others are really smart. They were able to come up with a casting method. Now they have solved some of the problems I was worried about. Well, now I just need to figure it out again. With a grinding machine, it’s not difficult to make the bike look like the drawing.”

"Grinder" Alela was slightly confused after hearing this, tilted her head and asked: "What is a grinder?"

"It's a machine for polishing parts." Mi Xiaoan explained, and then smiled: "I haven't thought about the details yet, but it should be well designed. Give me some time and I can design it."

"Oh, that's it." Alela nodded slightly after hearing this, and then urged: "Then hurry up and design it, so everyone can take a good look at your ability."

As she spoke, she glanced around, with pride in her eyes: Look, this is my daughter, designing something is just for fun, why don’t you hurry up and learn?

"Let me think about it first." Mi Xiaoan saw this and smiled bitterly: "I don't have any ideas in my head right now. I'll talk about it later."

"I haven't thought about it." Alela couldn't help but feel a little disappointed when she heard this, but she couldn't say anything. She picked up another fruit from the table and said, "Then think about it first. When you think about it, you must tell me first. "

"Yeah." Mi Xiaoan stuck out her tongue coquettishly, then stood up and left her seat. When Madeline saw this, she rolled her eyes at Alela and said somewhat reproachfully: "You, you, why did you tell An to work as soon as you came back? Be careful, she won't recognize you as your mother in the future."

"Hehe, it's okay." Alela didn't dare to refute Madeline's words. She scratched her head in embarrassment and said, "Our An is very smart and ruthless. It's just a matter of asking her to think of a way. It doesn't take any effort at all."

"Haha, just praise your daughter in a different way." Madeleine smiled playfully, and then she stopped talking, asked a few people to sit down, and began to ask about the Dwarf Mountains.

Mi Xiaoan's side.

After leaving the stone table, she looked around and immediately saw Keerna and the others sneaking around the bicycle. She didn't know what they were doing, so she walked over curiously.

"Hey, let me ride first, you guys don't know how to ride." Kelna was saying in a low voice.

"Then you know how to do it?" Elaine immediately began to retort, pouting: "Everyone is only half-measured, so it's better to let me go first. Ask me if I'm not afraid of falling."

"I'm not afraid of falling either." Kelna tried her best to show a brave attitude.

"Ahem, what are you doing?" Mi Xiaoan couldn't help but laugh out loud after standing behind and listening to their argument for a while.

"Hey" Kelna was startled, but when she turned around and saw that it was Queen An, she immediately breathed a sigh of relief and hurriedly came up to her with a happy face and said: "An, please teach us how to ride a bicycle, just like you Was it good to ride like that just now?”

"Okay." Mi Xiaoan nodded with a smile, walked up and took a look, turned around and asked, "Which of you comes first, or rock, paper, scissors?"

"Okay." Kelna and the others thought for a moment, looked at each other again and nodded. Then they greeted each other and formed a circle, punching each other.

Rock, paper, scissors is indeed the fastest way to resolve disputes. It only took two minutes for the girls to show off. The little warrior Sha Sha successfully broke out of the siege and became the first person. After Keerna's sour complaints, He walked out in a daze.

"An, please teach me what to do." She looked at the ugly bicycle in front of her excitedly and asked Mi Xiaoan.

"Go, ride on, I'll hold you up." Mi Xiaoan smiled and raised his chin at the bicycle.

"Oh." Upon hearing this, Shasha hurriedly stepped onto the car, as if she was afraid that someone would snatch it from her.

Mi Xiaoan couldn't help laughing again when he saw this, stabilized the car, and carefully taught Shasha to move forward.

If the girls came to play by themselves, there would probably be elders who would dissuade them, but since Mi Xiaoan was here, those elders wouldn't say much. Instead, some gathered around to study secretly.

More than ten minutes later, Shasha and Elaine had learned how to ride a bicycle and acted as little teachers to the remaining companions. Upon seeing this, Mi Xiaoan retreated and stepped aside to rest.

She was going to start thinking about the grinder.

Now that there is a casting method to cast bicycles, it is imperative to get a grinder to eliminate defects.

As for how to do it, I really need to think about it carefully.

To be honest, this is the first time Mi Xiaoan has thought about designing something by himself. Those clever tricks in the past were just copied from the original world. Therefore, even though you only need to design an extremely simple one, you still have to think about it carefully.

A grinder? It definitely requires a grinding stone. There are plenty of these among the dwarves, so there is no need to worry about raw materials. She gently summoned the system and drew a small circle on the light screen to represent the polishing stone.

Then next, you have to think of a way to fix the parts. Other things are fine, but the chain parts are too small and will be injured if you hold them with your hands. How to fix it

Well, probably a card slot similar to a mold will do.

How else to operate it? Pull it up and down? This seems feasible. Put the grinding stone parallel to the mold and rub it up and down alternately to achieve the purpose of polishing.

But isn’t it too troublesome? There should be an easier way.

Wrong, the shape of the millstone

Place the grinding stone parallel to the mold and make it into the shape of a grinding disc. Add a hand lever to it for shaking. This will make it faster and less laborious.

As for the mold, it seems that it can be designed into a multi-mold situation, that is, there are many slots on one mold, and many parts can be polished at one time. Well, this is definitely good.

With Mi Xiaoan's conception, the pictures on the light screen also changed again and again, and finally they were completely finalized into the shape of the millstone that Mi Xiaoan thought about:

The round heavy grinding stone is on top, and there is a heavy grinding stone with a rocker on it. After being turned manually, the parts below can be polished by its own gravity, and heavy objects can also be artificially added to the grinding stone. , to increase the intensity of polishing.

As for the bottom, there is a circular mold with many die holes, which can add dozens of parts at one time. The mold hole is slightly deep, so that the power of grinding will not directly displace the part. At the same time, it can just protrude the out-of-shape part, so that the grinding stone can be removed at one time.

Hey, it’s really simple

Looking at the simple grinder she designed on the light screen, Mi Xiaoan had a satisfied smile on her face. She looked at it carefully again and saw that there were indeed no omissions, so she began to think about other aspects:

The production of chains and other small parts requires very high precision. Although the cast parts are not very different from each other, there will inevitably be some differences, and you have to find a way to measure them.

Yeah Vernier caliper

Mi Xiaoan easily thought of it. This kind of tool that can accurately measure without even needing a scale is of course the first choice. Thinking in her mind, she added the structure of the vernier caliper to the light curtain, and finally breathed a long sigh of relief.

After getting up and stretching, she saw Keerna and the others still playing with their bicycles happily. However, there were already elders watching, and they were not afraid that they would be hurt. Mi Xiaoan thought for a while, and did not go there. He turned to look at Madeline.

Madeleine and the others had already left their seats at this time and were saying something next to the Holy Tree. Judging from the way they pointed, they should be talking about the Gate of the Holy Tree.

In the more than half a month that Helena has been going back and forth, the changes in the holy tree have become more and more serious. The gap on it, which was originally only a palm wide, has now expanded to a size large enough for a person to fit inside.

But the strange thing is that the scene inside the gap is still dark, and nothing can be seen, as if there is something in this gap that can swallow even the light.

Regarding this question, Mi Xiaoan once asked Madeline, and the answer she got was always the same. As for the specifics, even she couldn't tell.

Thinking in his mind, Mi Xiaoan walked towards the holy tree to see if he could hear something secret.

"It will take a few more days before we can start." Alela asked happily, looking at the gap that had become the door.

"It should be." Madeline smiled and nodded: "This time the opening is much faster than before. It has only been opened to this extent in more than 20 days. It seems that it will take at most five days to complete. Let the kids in.”

"That's great." Alela sighed, raised her head and said, "If it wasn't for the Moon God Festival, I thought these children would never grow up. Now, they have finally grown up."

"Who isn't?" Madeline chuckled and asked: "Hey, by the way, Helena told you that your daughter has the same ability as the high priest a thousand years ago. She can talk to the holy tree. Yesterday I asked the Holy Tree for me when I was here, and it said that five life seeds have been condensed."

"Five is still a bit too little." Alela glanced at her brows with dissatisfaction and asked with some expectancy: "Then can An discuss with the Holy Tree and let it prepare one specially for An? After all, our family If Ann is so smart, the children she will give birth to will also be smart."

"That's it." Madeline looked at the other people around her and said a little embarrassedly: "But An said that the life seeds of the holy tree are given randomly and cannot be discussed."

"That's it. I really hope that our family An can give birth to a child this time." Alela sighed in disappointment after hearing this. She turned to look at where Mi Xiaoan was just now, only to find that she was already behind her and immediately glared. He closed his eyes and said, "Hey, this Moon God Festival, you must try your best to have a child, you know, or else I'll beat your ass to pieces."

"No," Mi Xiaoan immediately made a bitter face when he heard this, and argued: "Grandma told you just now, it's random. If she can't give birth, there's nothing I can do about it."

"I don't care." Alela raised her chin arrogantly and squinted: "Anyway, you must be one of the five people, otherwise I will lose face, huh."

"" Mi Xiaoan was about to cry, but after a while he nodded and said, "Okay, okay, I'll try my best."

The distribution of life seeds is actually not what Mi Xiaoan told Madeline. The Holy Tree even asked Mi Xiaoan if he wanted to allocate one to her, but she refused.

As she said before, she wasn't ready to have a baby yet. After all, I couldn't accept the fact that suddenly a little girl was chasing me and calling me mommy. I even got goosebumps just thinking about it.

"You are so good." Seeing her daughter's obedient appearance, Alela nodded with satisfaction, and then asked: "By the way, it's been more than half an hour since you figured out how to do this with your sander."

"Of course I have thought about it." Mi Xiaoan raised his chin proudly and said proudly: "As long as this grinder is manufactured, the bicycle can be made exactly like the one I drew. It won't matter how we use it ourselves. It will definitely fetch a good price.”

"Well, my daughter is really smart." Alela immediately became proud after hearing this. She pushed Mi Xiaoan and said, "Go, quickly draw the drawings and let the elders consult with you."

"Uh, okay." Mi Xiaoan nodded after hesitating for a moment. Anyway, this thing has to be drawn, and it's the same now.

Thinking in her mind, she returned to the stone table, picked up a pen and paper, and began to trace the image attached to the paper by the system's light curtain.

The overall picture, the fragmented structural diagram, and the image of the vernier caliper were all drawn in a short time. Mi Xiaoan added some notes to the various parts of the structural diagram. Then I thought for a moment and drew a second copy. After all, it goes without saying that Madeleine would definitely want one to stay in the clan.
