Lin Yi said: "Finally, there is another difficulty, that is, inspection, I hope that I can make a machine that can automatically detect the authenticity of invoices, the production of this machine is mainly designed and produced by Li Yu, and if you need Zihuai's cooperation, you can find him." ”

After Lin Yi assigned the matter, she followed Zihuai to the world to embroider, and after seeing some of the finished products that have been produced so far, she feels that she is still very satisfied, and she must be able to attract a lot of attention at the future commodity trading conference.

Because there was no order yet, Lin Yi felt that these finished products were enough, and it happened that Chenguang Paper Mill needed manpower, so she transferred some of Zihuai's people from Tianxia Embroidery to work on Chenguang's side.

Because the matter of invoices is very important, and it must not be taken lightly, so Lin Yi's trip back to Ninghe County was temporarily canceled, and she also went to Chenguang Paper Mill to study the production of invoices with Zihuai.

After ten days of research and hard work, Chenguang Paper Mill finally made the first version of the fixed amount invoice.

Lin Yi sent a sample to Li Yu and asked him to use it to test his new machine for inspecting invoices.

Three days later, Li Yu's ticket checker passed the test, and the three of them were very happy.

In this process, Tao Shiyi, who has been following Lin Yi, also participated in some of these things, and when he finally succeeded, he also had a strong sense of pride and pleasure in his heart.

At this moment, he looked at Lin Yi's ecstatic appearance, and suddenly felt that Lin Yi at this moment was not only the wife of the master he wanted to protect, but also a very thoughtful and courageous master leader.

On the same day, Lin Yi and Zihuai came to the official yamen with the invoice sample and the ticket inspection machine, and they went to the household registration department first and found Fan Xian.

When Fan Xian heard that the invoice was made, he was looking forward to it, and hurriedly urged Lin Yi to open it and take a look.

Lin Yi said with a smile: "Go and invite Nan Daren over first, you won't have to see it, and you have to show Nan Daren again." ”

Fan Xian hurriedly asked his assistant to invite Nan'an.

Fan begged Lin Yi and said, "Mrs. Ji, can you show me now, you don't need to tell me now, just wait for Lord Nan to come and talk about it." ”

Lin Yi looked at his anxious appearance, and said with a smile: "Good things have to wait, Fan Sibu will wait for a while, and we will look at it together when Lord Nan comes." ”

Fan Xian had no choice but to wait.

Fortunately, Nan'an came quickly, and it didn't take long to arrive.

As soon as he walked to the door, he couldn't wait to say, "Mrs. Ji, I heard that you have made an invoice, what does it look like?" Let's take a look. ”

Lin Yi smiled back and glanced at Peach Eleven next to him.

Peach Eleven put the box he was holding in his arms on Fan Xian's desk, then opened it and took out a strange stack of papers from it.

Nan'an and Fan Xian were taken aback when they saw it.

Fan Xian looked at it and asked, "Mrs. Ji, can you pick it up and take a look?" ”

Lin Yi smiled: "Of course you can." ”

Fan Xian hurriedly picked up a sheet, put it in his hand and looked at it over and over, only to see that the paper, about a palm long, was neatly rectangular, the paper was a little hard, and it looked a little shiny.

On the top of the invoice, the amount, city and number of the invoice are written, as well as the barcode of the vertical bar.

On the reverse side are some statements and notes, and in the lower right corner, there is a small gray dark bar.
