After returning to the factory, Xiaohua was already processing Zhu Gang's parts. She saw Zhang Yi coming in with a lot of books. "Brother, you bought the books back. Let me take a look."

He dropped the machine tool and jumped towards Zhang Yi.

Last night, Xiaohua officially recognized Zhang Yi's mother as her godmother, so Xiaohua was upgraded from Zhang Yi's employee to Zhang Yi's sister. This made Zhang Yi very speechless. He never thought that in just one night, he would become more

Got a sister.

Moreover, this sister was hired by him from the Xueba Mall with money, and she was not a human being, or in other words, not a pure human being.

He could think that if Zhang Yi stopped hiring Xiaohua in a year, his mother would definitely want him to look good.

After the two brought the books to the office together, Xiaohua flipped through the books casually.

"Brother! You just bought these books! Many of the contents in these books are repeated, and several of them are completely useless." As she said this, Xiaohua picked out a few of the dozen books, and

He carefully put them aside, and then said to Zhang Yi; "Brother, these are the only books that are useful to me. Others, such as mechanical basics, etc., are useless to me. After all, I am not a machinist."

Beginners, let alone even beginners, many of the books here are useless."

After listening to Xiaohua's words, Zhang Yi was a little depressed. Most of the books he spent a whole morning buying were useless. How could this not be depressing?

However, in their small county town, Xinhua Bookstore only had these mechanical books. If he wanted to buy more, he could only go to large bookstores in the city or province.

Just when Zhang Yi was worrying about where to buy books, he suddenly felt that he was really stupid. Today's human beings have already entered the Internet era. Why not buy them online? He foolishly wanted to rush to the city or province.

Purchase from Xinhua Bookstore.

So he immediately turned on the computer in the office, and skillfully entered a certain baby's shopping website, entered the words "machining books", and countless machining books immediately appeared.

At this time, Xiaohua has not left yet, and is also very curious about Zhang Yi's operation. Although computers are not unique to Zhang Yi's earth civilization, Xiaohua and the dwarves also have them, but they are different from the earth's.

Computers are different. Their computers are basically pure computers and do not have the ability to network on a large scale. Moreover, their civilization does not have the same Internet as Earth, so there is no such thing as online shopping.

Seeing that Xiaohua didn't go out, Zhang Yi asked Xiaohua to choose some useful books on the website. However, after Xiaohua selected a few books, she didn't choose any more because she felt that they were almost done for the time being.

So he said, "After reading these books first, I will buy them if necessary."

"Okay! I'll listen to you!" Zhang Yi replied.

"Brother! Then I'll go to work first."

After Xiaohua finished speaking, she went out to start the machine tool and continue processing parts. After all, five thousand parts had to be completed within four days. This was also stressful for Xiaohua, because Xiaohua was also a flesh and blood body, not a machine. She also

You need to eat and rest.

In fact, in less than one morning, Xiaohua has already machined out a lot of parts. According to Zhang Feng's rough estimate, she has processed at least 400 parts. If calculated according to this efficiency, then

It seems a bit difficult to complete this batch of orders in four days.

Later, Zhang Yi also walked out and came to Xiaohua's side. After processing a part, he said to him: "Xiaohua! I'll go out for a while. You can go back after lunch! I'm going to register some patents."

"Yeah! Got it! Go ahead! Just have me here!" Xiaohua said to Zhang Yi without raising her head.

Then Zhang Yi returned to the office, took out the drawings he had placed before, then got into the minivan parked at the door and drove towards Zhoutai City, which is about two hours away from his home in Xian County.

’s journey, which means that it would take noon for him to arrive from Xian County.

Along the way, there was a lot of traffic, and Zhang Yi didn't arrive at the patent office until around one o'clock in the afternoon.

Although the review of patents is now very fast and there are not many procedures, since it was Zhang Yi's first time to apply for a patent, he still made a lot of jokes when he applied for patent review.

Fortunately, in the end, Zhang Yi completed the application for the aerodynamic bicycle itself and its extension patent with the help of a patent office staff member named Zhang Yingying.

Although the structure of a pneumatic bicycle does not seem complicated, there are more than a dozen patents generated by pneumatic bicycles. Although many patents are not very useful in Zhang Yi's opinion, he still applied for them.

Of course, many of these patents are very practical, such as pneumatic motors, mechanical tires, decompression valves, etc. These patents can not only be used on Zhang Yi's aerodynamic bicycles.

For example, in addition to being used on Zhang Yi's aerodynamic bicycle, pneumatic motors can also be used on pneumatic tools such as air cannons, air hammers, and pneumatic drills. As for pressure reducing valves, they are even more useful, and mechanical tires are also used.

It can be used on cars and other means of transportation, so it was not completed until about four o'clock in the afternoon.

"Ms. Zhang! Thank you for your help this afternoon. Otherwise, I don't know what I should do. I wonder if I would be honored to invite you to have a meal with me!" When the patent application was about to be completed, he expressed his gratitude to the man who had been helping him with the patent application.

Said a patent office staff member named Zhang Yingying.

After listening to Zhang Yi's words, Zhang Yingying did not answer immediately. Instead, she raised her head and looked at Zhang Yi, and then said, "No need! I have something to do after get off work today, so let's do it next time!"

After listening to Zhang Yingying's words, he said: "Okay! But next time, Miss Zhang, don't refuse."

When Zhang Yi got home, it was already evening, and Xiaohua had also come back, so he took a hurried rest after eating.

"Brother, all the accessories are completed. You must treat me to dinner tonight." Time passed very quickly. On the afternoon of the fourth day, while Zhang Yi was carefully looking at the aerodynamic bicycle drawings, Xiaohua's cheers came from outside.

So Zhang Yi packed up the drawings and said to Xiaohua who just came in: "Okay! Let's go have a big dinner together in the evening."

Then Zhang Yi and Xiaohua loaded all the finished parts onto a small truck and transported them to Zhu Gang's factory.

"Boss Zhang, it's really your job to complete the processing of 5,000 parts so quickly. Even if our factory uses CNC machine tools, it would be very difficult to process so many parts in such a short period of time. This is amazing.

Is this still a transfer? I will transfer the money to you now." After saying that, Zhu Gang picked up his mobile phone to transfer money to Zhang Yi.

"Boss Zhang, I don't know if you are interested in taking another order. If so, then I just have an order for Jili in my hand, and the time is a bit urgent, but the profit is very considerable." When Zhu Gang

After transferring the money, he said to Zhang Yi.

After Zhang Yi heard this, he did not answer immediately. Instead, he thought about it and then said to Zhu Gang, "Okay! Thank you, Boss Zhu."

In the end, Zhang Yi agreed. After all, Zhang Yi's factory is still very small. Apart from an old-fashioned machine tool, there are no other machine tools in the factory. Now that Zhu Gang has an order, of course Zhang Yi

To come next.

After all, the mechanical processing industry is different from other industries. If a factory wants to produce and develop, it must have a list. Of course, it can also produce its own products and then open up sales channels. However, these are still a bit far for Zhang Yi's workshop. After all, he

Now there are not even decent factories, let alone sales.

Although he already has a product, the equipment to produce this product cannot be the same. So if he wants to produce aerodynamic bicycles, he still has to buy a lot of equipment, and the little money he has now is still
Chapter completed!
