After Zheng Dai extracted the fine suffering, the detoxification technique, and the basic visual illusion technique were activated, outside the door, the familiar embroidered aunt's loud voice came.

"How is the door open? Danne, you're back early today? ”

"Auntie, it's me back!"

"Xiao Zheng Dai?!" Aunt Xiu suddenly glared when she saw Zhengdai, threw down the vegetable basket directly, stepped forward and gave Zhengdai a 200-pound hug, and then put her hand on Zhengdai's shoulder and looked up and down.

"Xiao Zhengdai, you ...... everything"

"I didn't get a tan, I wasn't thin, and I wasn't hurt." Zhengdai replied with a grin.

Aunt Xiu stiffened, and was stunned for a long time before she said, "Xiao Zhengdai, you have grown taller." ”

This time, it was Zhengdai's turn to freeze, and after a while, he shook his head and said helplessly: "I've only been out for eight days, how can I grow so fast." ”

"It's just getting taller." Aunt Xiu insisted, and didn't ask why Zhengdai came back so early, whether the entrustment was carried out smoothly or not, in her heart, Zhengdai's safe arrival at home was more important than anything else.

"Tired, aren't you? Did you eat lunch or not? Auntie got you something to eat? ”

"I'm not busy, I'm not hungry. Let's wait for dinner...... Is Uncle Craftsman in the shop now? ”

"Where can he be when he's not in the shop, he must be happy to die knowing that you're back."

Zheng Dai smiled: "That aunt, I'm going to find Uncle Craftsman, and I have something for him to help me get down." ”

"The long knife he gave you is broken again?" Aunt Xiu frowned dissatisfiedly: "Your uncle can't do something serious, I'll talk about him in the evening!" ”

"Well, no, no, it's some other little thing...... Auntie, I'm out! Just as he was wearing it, he turned around and walked out, and suddenly there was another pause.

"It didn't work for days, and I almost forgot about him. Water escape - the art of water body! ”

When the water body appeared, he consciously walked to the main room and continued to practice the newly learned techniques.

……

Uncle Craftsman's blacksmith shop is in the southeast corner of Konoha Village. It is said to be a blacksmith shop, but it is actually a dilapidated house with ventilation on all sides, and a large stove - an oven is placed in the middle.

Although it is simple, all the financial resources of the Dai family in the past few years were hammered out by Uncle Jiang here.

Some of the ninja tools made from here were supplied to the Konoha ninja clan, some to the weapon shop, and during the war, a large part was directly supplied to the village.

In the past two years, about forty years ago, Uncle Jiang's physical strength began to decline, so he accepted two apprentices, both of whom were eighteen or nineteen strong young men, and even the eldest apprentice had entered the ninja school to study, but unfortunately he did not succeed in graduating and became a ninja.

When Zheng Dai arrived, Uncle Craftsman was sweating and panting, standing aside and instructing the two apprentices to pick up the sledgehammer and hit the small hammer.

The sledgehammer was forged, the small hammer was commanded, and the key positions were modified, and soon, the hard iron became the shape of the kunai, which was then quenched and tempered, and the kunai became sharp and formidable.

In just three or two minutes, a kunai was successfully built.

Quietly watching this, Zheng Dai only moved over and walked over: "Uncle Jiang, Brother Yeshi, Brother Kagu." ”

"Wearing it?" Uncle Jiang was stunned for a moment, and soon showed a smile: "Are you back?" When did you come back? Didn't you say you would have to go for more than a month? ”

His two apprentices nodded to Zhengdai in greeting.

"As soon as I came back, there was an accident, so I went back to the village early." I am wearing back.

Uncle Jiang nodded: "Your aunt saw you, right?" I've been talking about it these days...... Hehe, don't talk about it, if you talk too much, you go home and talk to her, and she has to say that I talk a lot. ”

"Am I the kind of person who talks little?" Zheng Dai smiled: "Uncle Jiang, I came here to have some small objects that I want you to help build, are you busy now?" ”

Uncle Jiang was stunned for a moment, and said happily: "I'm not busy, I was only busy when I was fighting in the first two years, and at that time, these two boys didn't help me, and they almost exhausted me to death."

Say, what do you want? It can't be that the long knife I made you has a problem again, right? ”

"No, no, I want you to get me a bike."

“…… Bicycle? A carriage that runs on its own? Toy cars? How old are you......"

Sure enough, no? Zheng Dai secretly pondered, and continued: "No, Uncle Craftsman, you listen to me......"

Last night, at the hot spring inn, Asma casually mentioned 'what kind of bicycle do you want', which caused Asma to be puzzled, and it was only then that Dai reacted, and there didn't seem to be such a thing as a bicycle in the Hokage world.

And in terms of transportation, it is very scarce. (Please ignore Boruto)

You said that if you want to get a train, get an airplane or something, you are wearing an ordinary college student before crossing over, but you really don't understand it.

But to talk about making a bike by hand......

Well, still not quite really.

But he can describe it.

The most important thing is that there are strollers in the Hokage world, the kind that pushes and walks, and wheelchairs, which are also the kind that pushes and walks.

You are only one axle, one chain and two pedals away from the bike, right?

God knows if there are those things, why are there no bicycles, maybe Kishimoto thinks that the ninja is pedaling a bicycle and is a little unsightly?

Maybe it's too cumbersome to draw, after all, even running has cut corners and put it back with two arms.

In short, an hour later, a model bicycle was successfully made.

The size of the model is about 1:20 in proportion to the real bicycle, and I am wearing a half-squatting and carefully observing for a long time, consciously and in memory.

"That's it, get a size I can ride on, okay, Uncle Craftsman?"

Uncle Craftsman picked up the model and looked at it: "Be fine, you can run, right?" It's not a small difficulty, that is, your uncle and me...... Kagu, go to the wheelchair shop and choose two medium-sized wheels to buy them back, just change it and that, save trouble. ”

"Uh...... Master, only buy wheels? ”

"Nonsense, do you want a wheelchair?"

Kagu walked out with a tangled expression.

"Ye Shi, come, let's take this first...... The most strenuous car chain to get out. ”

"Uncle Jiang, I can help."

"Hmm, you haven't wielded a hammer in a long time, have you? Your kid is stronger than Uncle now, come on. ”

The four of them were busy from two o'clock in the afternoon until it was faintly dark, and the first bicycle in the Hokage world was finally available!

Uncle Craftsman pushed the bicycle and pushed it out for more than ten meters, feeling a little jerky, and only then did he remember that the bicycle with a chain needs to be smeared with special lubricating oil or engine oil on the chain.

After being busy for a while, he got oiled, got on the car, and pedaled two steps, if it weren't for the fast eyes of Zhengdai, he would have been able to fall apart with himself and the bicycle. After being scolded by Uncle Craftsman, he hesitated for a while and didn't dare to get into the car by himself.

"Xiao Zhengdai, can you try it?"

Zhengdai was already itchy, so he immediately pedaled a few skilled pedaling steps, stepped on the bike, rode out, and soon turned back.

"The copper wire of the brake is not tightly wound enough, and there is a back, can you add a seat with people?"

Uncle Jiang was stunned and said with a smile: "Who do you want to bring?" Little red beans? Haha, easy! ”

Tied up the copper wire, added the back seat, and rode on the bike again, kicking out without looking back.

"Thank you, Uncle Jiang and the two eldest brothers, I'll go around and go home for dinner in an hour!"

Looking at Zhengdai's figure in the distance, Uncle Jiang was stunned, and laughed loudly and scolded: "Stinky boy, you have really grown up, are you so eager to find the little girl with red beans to show off?" ”

"I'm not looking for a little girl, I'm looking for a little sister!"

Uncle Jiang was stunned again: "Little sister? Who? This kid ...... Where is the young lady ......?"
