Chapter 60 Blank Express

During the three-day rest, Chen Xingyang did not bother Yu Fan, even though he had a new case to communicate with Yu Fan.

Yu Fan didn't go anywhere, just tidyed up the house at home, went for a run in the community, read a book, and listened to soft music.

Although his body is on vacation, Yu Fan's mind is not idle at all. When he is free, he takes out the strange "sulphur atom electron layer" map and looks at it, looking forward, backward, and sideways. Looking vertically, he still couldn't see any clues. Yu Fan thought for a while, only to see if he could find clues from the courier brother who delivered the courier to him.

Today is the last day of the holiday, and Chen Xingyang sent a WeChat message very early: "Old Yu, are you free tomorrow? Let's meet and chat. I would like to invite you to refer to some situations."

Yu Fan thought for a while, and replied: "I'm not free tomorrow, the company has something important, let's talk about it later." Right now, Yu Fan just wants to figure out this prank, because it has troubled him for a long time.

The next day was the first day of work in the new year. There were a lot of cars on the road, but this did not affect Yu Fan, because he walked to the office every day, not because he had to walk fast, but because Yu Fan liked the process of walking. During this process, he often thinks about problems, and many sources of inspiration are also learned from the process of walking.Many unique formulas are also thought of on the way to the laboratory, rather than born in the laboratory.

Just like learning scriptures from the Western Paradise, the real scriptures are not actually in the Western Paradise, but on the way to learn the scriptures.

When we arrived at the company, everyone had a happy and busy expression on their faces. We greeted each other warmly and talked about where we went during the holidays. Then we quickly dealt with the things at hand and started a busy day.

Yu Fan found Cao Ben, exchanged some greetings, and then got straight to the point: "Old Cao, what happened to the courier I asked you to read for me that day?"

Obviously, after a few days, Cao Ben seemed to have forgotten about it: "Huh? Uh... express delivery? Oh, I remembered, you asked me to find out who came to the company in the afternoon a few days ago, right? Um, There was only one courier, and there was no one else."

Yu Fan: "What about the courier? Can you help me find out who delivered the courier?"

Cao Ben scratched his head embarrassingly: "Oh, I forgot about this, it doesn't matter, the courier is in the express box at the door, just take a look and you will know."

Yu Fan jokingly knocked Cao Ben on the head, teasing him about his forgetfulness.But it is also understandable that before the holiday, people are absent-minded. The body is in the company, and the heart may have flown home.

The express box was opened, and there were five express documents lying in it.

But an interesting and strange thing happened again. The delivery times of the four couriers were all sent during the holidays. Only one courier did not know, because this courier bag was very special, and the color on the courier bag turned white, like being soaked in water. But what is even more strange is that the courier slip that was originally posted on the courier turned out to be a blank piece of paper!No sender, delivery time, address, nothing.

Cao Ben was puzzled: "Hey? What's the matter with this express delivery? Why is there nothing?"

Yu Fan asked Cao Ben: "Has anyone touched the express box these days?"

Cao Ben: "Impossible, I have the key to the express box."

Yu Fan reasoned: "Then, this San Wu Express should be delivered by the courier brother you mentioned that day?"

Cao Ben nodded: "It should be like this, but there is nothing on this courier, how did he deliver it?"

Yu Fan smiled relaxedly: "Oh, that's it, then this should be an advertisement, probably selling a house, getting a fitness card, etc. It's okay, go get busy." Yu Fan made up a cover to distract Cao Benz, he doesn't want innocent people to be involved in this "prank" that he doesn't know what the circumstances are.

Cao Ben nodded and went to work.

Yu Fan took this document bag into his office, closed the door, put the courier document bag in the middle of his desk, and looked at it carefully for a while. Could it be that this courier boy is not a courier?Is it pretending to be a courier, to drop in such a blank file bag, and then the real purpose is to sneak into the company and stuff that weird pattern of paper into the bag that Yu Fan is going to bring to BJ City?
The more he thought about it, the more he felt that this courier boy was suspicious, but the more suspicious he was, the closer he was to prove that Yu Fan was getting closer to the truth, which made Yu Fan excited again.This feels like we were looking for a treasure chest that sank 100 years ago in the sea. With our hard work, we finally found the treasure chest. Although the treasure chest is locked, we cannot get the treasure temporarily, but our goal is clearer than before Alright, all we need to do is - open the lock.Soon the truth will be revealed.

Yu Fan geared up, rubbed his hands to warm them up, and put on a pair of experimental nitrile gloves. He wanted to see what was in the file bag.Yu Fan carefully pinched the opening strip of the document bag with his hands. The document bag indeed seemed to have been soaked in water, and the paper became very soft.

With the sound of "hissing", the seal of the document bag was torn, and Yu Fan carefully opened the document bag. As soon as he opened the file bag, there was a pungent smell, and Yu Fan had to turn his head to take a breath of air.Continuing to widen the opening, Yu Fan saw a piece of paper lying in the file bag, yes, there was only one piece of paper.

Yu Fan reached into the file bag with his index finger and middle finger, and carefully twisted out the piece of paper. The paper was not big. With his other hand, he took out a piece of A4 paper and put it on the table, and then put the twisted paper on the table. On A4 paper.

Yu Fan took a closer look at the file bag again. There was nothing inside. Yu Fan tore off the side of the file bag again, and spread the file bag completely into a flat surface, wanting to see carefully if there was anything left inside. Mystery, but from the current point of view, this is an ordinary file bag, except that the color on the top is gone, there is nothing special.

Yu Fan threw away the file bag and began to study the paper carefully.This is a piece of almost white paper with a little pink print on it. There are 10 round holes on the left and right sides of the paper, evenly round holes.

Yu Fan picked up this piece of paper again, the texture of this paper was rather brittle, Yu Fan looked carefully at the back, it was also blank, there was nothing there, Yu Fan stood up again and took it to the window to face the sun, let Sunshine passed through this piece of paper, trying to see if there was any mystery, but found nothing.

Yu Fan sat down on the office chair with some frustration. What's going on?What exactly is the sender trying to convey?No matter how you look at this piece of paper, it is an ordinary white paper.What exactly does this mean?

Yu Fan slumped on the office chair blankly. Although it was the first day of the working day and everyone was busy, Yu Fan's office was very quiet, and he could clearly hear the busy voices of everyone outside the office, "President Wang, New Year's Eve! Happy, the new year is here, do you have any order requirements?" "Mr. Li, you agreed to pay back the year before, why haven't you paid it after the new year?", "Ah, yes, I will come to your factory this afternoon to have a look , Okay, that’s it.”, “Xugong, have you received the invoice I sent you years ago? Oh, okay, it’s good if you received it, I’m afraid I’ll forget it after so many days of vacation.”

Suddenly, Yu Fan sat up. Since he couldn't find the way in front of him, maybe there was a mistake in the starting point of our reasoning?
