He said it is easier said than done to find a solution.
Because the software stored in this USB flash drive was made by Qiao Nian in a week, he just finished perfecting the last bit of code in the office software at noon.
The deadline for the software competition is imminent, and losing the USB drive at this time will undoubtedly mean losing the qualification to participate.
Liang Conglin had no choice but to look for it.
*
In the security room of Tsinghua University.
The principal and several school leaders came.
The small security room was packed with people.
Du Mingwei no longer had the high spirits and enthusiasm he had when he asked Qiao Nian to transfer to another department at noon. He was so anxious that his eyes were bloodshot. He covered his head with his hands, looking so guilty that he wanted to commit suicide.
"After Qiao Nian gave me the USB drive, I put it on my desk. After I finished talking to Teacher Luo, I went to look for it, but it was gone... I searched the whole office several times but couldn't find it... I searched in the drawers and under the desk. I almost turned the whole office upside down."
"But it's not there... It's like the USB drive disappeared. I couldn't find it anywhere."
The computer teachers who were with him had similar reactions. They all looked embarrassed and stood on tiptoe, as if they had made a mistake.
"We also helped to look for it, but there was no USB drive in the office."
“…How could such a good thing disappear?”
Principal Liang and the school leaders were calmer than them, especially Liang Conglin, who had seen a lot of things. Although it was his first time to encounter such a thing, he remained calm and said to the anxious teachers from the computer department, "Don't worry, let's check the surveillance first. Think about it, who else has entered the office besides you?"
Du Mingwei and several computer science teachers looked at each other. Who had entered their office? This... their office was always open to the public, and students often came in and out to ask them questions. They really couldn't think of who was suspicious at the moment.
Du Mingwei frowned, and remembered something: "At noon, several students from the department came into the office to help move teaching materials... but they left after moving the things... In addition, several students came in to ask about academic matters..."
Who is Liang Conglin? Before he could finish, he immediately grasped the key point of his words and emphasized: "You said that a student came into the office to move things at noon?"
Du Mingwei grabbed his hair, looking a little annoyed, as if he didn't understand what was wrong. "A few students came in to move things, but we called them to help."
"Principal, is there something wrong with this?"
Liang Conglin didn't say anything, he just asked about the approximate time when his students came and the time when Qiao Nian handed in the USB drive and left.
With a solemn expression, he ordered the security guard in front of the surveillance camera: "Please pull up the surveillance camera at 12:30 noon so that I can have a look."
"Yes, Headmaster."
It was the first time that the security guard saw so many school leaders coming to their small place. He nervously operated the computer and called up the surveillance footage of the time Liang Conglin mentioned.
Liang Conglin looked at the students entering the office on the surveillance camera, pointed at the people on the monitor, and asked Du Mingwei and others majestically: "Professor Du, can you check if there are any strange people among the students on the monitor?"
“???” What do you mean by a strange person
Du Mingwei raised his head and looked at the surveillance video. As he was watching, he suddenly realized that something was wrong. He frowned and called the security guard to pause the surveillance video.
