"Wait a minute, I found a hole in this pocket. Lu Wanwan didn't take her coat off herself, she put her hand in the hole in the pocket.

"There's a small note!" After speaking, Lu Wanwan handed the note in his hand to Ji Yuze.

Ji Yuze took it, and through the light of the computer, he saw the words written on the note:

Be sure to take a picture of what's inside the computer, here's the proof!

The password for the computer is: 19710108.

Ji Yuze followed the prompt of the note, entered the password, and the computer was turned on.

The computer screensaver is a girl wearing a school uniform looking at the camera and laughing.

"Isn't this the girl in this photo?" Lu Wanwan picked up the photo in a frame on the computer desk.

Inside is a girl on a computer screen, also wearing a school uniform, and there is a person standing next to her, and both people in the photo are smiling happily.

Ji Yuze knew that this girl was the daughter of the owner of this office.

"What evidence should we take on the note?" Lu Wanwan wondered.

Ji Yuze moved the mouse and clicked on "My computer." ”

The computer desktop only has office software.

Ji Yuze looked around and found that the entire computer only had the most basic software. Then Ji Yuze clicked on the terminal of this computer, and after entering the code, he found that this computer was really clean and did not have any hidden files.

"It shouldn't be. Lu Wanwan spoke.

"If the information on the slip of paper was useful, the computer couldn't be so clean......"

Ji Yuze spoke: "There should be a USB flash drive." ”

"USB flash drive?"

Ji Yuze said: "When I opened the antivirus software on this computer just now, I found that there was a piece of hardware that was not safely deleted last time. Ji Yuze opened the information in the antivirus software to Lu Wanwan, and Lu Wanwan bent down and approached the computer screen.

Ji Yuze continued: "In this computer, all the files are neatly arranged and arranged in strict chronological order. I looked at the contents of each document, and it was the grade statistics of each grade and class. ”

"So, I was wrong about thinking that this place wasn't a teacher's office?"

"Well, it stands to reason that a teacher's computer will not have any emails to and from other schools other than transcripts. Ji Yuze clicked out the email noodles on the computer.

Lu Wanwan asked, "That could be the office of a certain head teacher?"

"It's supposed to be the principal's office. Ji Yuze replied.

"And now?" Lu Wanwan straightened up.

Ji Yuze said: "Find a USB flash drive." ”

After speaking, Ji Yuze stood up from the computer.

Lu Wanwan was still puzzled: "Looking for a USB flash drive?" Mr. Ji, I still can't understand why there must be a USB flash drive?"

Ji Yuze said as he looked for it: "The overall style of this office is clean and tidy, which can explain the character of the office owner to a certain extent, and there is a sixty percent chance that it is orderly, plus the computer file arrangement just now."

The analysis of the columns, as well as the placement of the mouse at the beginning, can show that the owner of the office loves to be clean. ”

Ji Yuze walked to the bookcase and said to the books inside: "Moreover, the discharge of the books in the bookcase, at the beginning, the books in the entire bookcase gave me a very chaotic visual experience, but later I found that in fact, the books in the bookcase are arranged according to the chronological order of each book's publication." ”

"Huh?" Lu Wanwan couldn't help but glance at the computer and said, "It's like the order of the files in the computer?"

Ji Yuze nodded: "Yes." ”

Lu Wanwan walked to the bookcase.

"The breakthrough was when I saw the placement of these two books, and the normal order should be the first and second books, all the way up to the fifth, but. Ji Yuze pulled down two books from the bookcase.

"The third book is placed in reverse order with the fifth book, and the order here is one, two, five, four, three. ”

Lu Wanwan took over the three or five books from Ji Yuze's hands.

"Maybe it's just a random place?"

Ji Yuze said: "You turn to the first page and look at the publication time of the third and fifth volumes. ”

Lu Wanwan opened the book according to Ji Yuze's instructions.

"They were all published in the same year, but the third volume is dated six months later than the fifth?" Lu Wanwan frowned.

"What order is this?"

Ji Yuze took the third book, closed the book, and put his finger on the book cover.

Lu Wanwan saw the words under Ji Yuze's fingertips:

The third volume is out of print and is on sale again, on a first-come, first-served basis!!

"The third volume has the best sales, obviously, the first edition is out of print, and it is clear that this third volume in my hand is a reprint. After Ji Yuze finished speaking, he put the two books into the bookcase in the original order.

"So, the owner of this office has a great obsessive-compulsive disorder about time?" asked Lu Wanwan.

Ji Yuze said "um" and said:

According to the previous inference, it shows that the owner here is very organized. ”

"Then if you want to unplug the USB flash drive from the computer, you should follow the prompt process of the computer step by step, and you should safely remove the hardware before unplugging!" Lu Wanwan was in a high mood.

Ji Yuze walked to the computer desk, propped his hand on the edge of the computer desk, and said, "So, the things in the USB flash drive are the key points on the note." ”

Lu Wanwan followed Ji Yuze's words and spoke: "Then it should be that the owner of the office didn't have time to import the things in the USB flash drive into the computer, and then directly unplugged the USB flash drive because of some unexpected situation." ”

"Hmm. Ji Yuze began to look for a place where the USB flash drive might be.

Lu Wanwan followed the skills she had learned from Ji Yuze before - using all available resources.

Then Lu Wanwan sat at the computer desk.

Lu Wanwan said: "If it were me, I would put the USB flash drive directly into my pocket." ”

"What if there are no pockets?" asked Ji Yuze.

"Then, pinch it in your hand and throw it into a corner while others are not paying attention. ”

Ji Yuze said: "I searched all the hidden places just now, but I didn't find the existence of the USB flash drive. ”

"Mr. Ji, I'll straighten it out

Now, what we already know is that someone must have come here at that time, and then the owner of the office was very anxious, pulled the USB flash drive from the computer, put it in his pocket or threw it somewhere. ”

"There is another situation. Ji Yuze said.

Lu Wanwan looked at Ji Yuze and asked, "What's the situation?"

"It's not that someone came out of nowhere, it's that he found someone. ”

Lu Wanwan felt that a gust of wind was blowing behind her.

"Mr. Ji, I feel like I'm getting goosebumps. ”

"But now it's all speculation. ”

Although Ji Yuze said so, Lu Wanwan deeply agreed with the possibility that Ji Yuze said.

The interrupted office owner was looking at the contents of the USB flash drive, and instead of slowly unplugging the USB flash drive according to his usual habits, he pulled it out directly, not the person who suddenly came in, but the person who had been hiding somewhere and had already come in, and was suddenly discovered by the office owner.
