According to Chunyu, in fact, he also complained a little about himself, because he used to work together in the archives room, and they were usually good friends, and they would often be together during meals, but that day, when Ma Lili refused, Chunyu didn't care at all.

Maybe it's because Chunyu itself feels a little belly barking, and after reminding her several times in a row, she saw that Ma Lili really didn't want to go downstairs, so she told Ma Lili to go first, and if she didn't see the other party coming, she would bring some food back to the other party.

After Chunyu left, he went directly to the school cafeteria, and they usually eat together, and they must basically rest at the same time as administrators, so the work and rest are almost the same, and when they go to the cafeteria to eat, there is always a commonality.

Many people often go to work together on a task, such as going to class, and if there is no big problem with the seats, basically the first time they sit in any place, the second time they will go to that place.

Or when making a bus, people who habitually choose which position they want will automatically choose that location the next time they get on the bus.

The two of them have such a habit.

So every time we go to the canteen together, there will be a fixed location, which is basically the same every day, so whether Ma Lili has come to the canteen or not, Chunyu can be seen at a glance and doesn't even need to look for it.

When the spring rain comes out, they have already eaten all the pieces, although there are many restaurants outside the school, but they are used to eating in the school canteen, although the taste is a little worse, but the price is very discounted.

However, the time is limited, the school is not open 24 hours a day, only the time for meals, so the local spring rain saw that most of the people had eaten and were ready to go back, and he was a little anxious.

During this period, Chunyu also called several times, but no one answered.

At that time, Chunyu still did not anticipate the seriousness of the matter, and must have been in the process of ordinary work, in order to organize the files, he often forgot to leave the mobile phone he carried with him in other places, so it was normal for no one to answer.

So Chunyu automatically helped Ma Lili buy some food, and then returned to the archive room with the food.

After coming to the archive room, Chunyu swiped his fingerprints and opened the door as usual.

But when he first entered the room, Chunyu felt a strange feeling, first of all, all the lights in the room were turned off.

At this time, it was almost dark, and the light in the room was very dim, but the computer in the main control room on the first floor was not turned off.

When you usually go out, common sense when the lights and computers are turned off is also the most important one, especially the computer.

Therefore, judging by the situation at the time, Chunyu could not be careless enough to leave the room without turning off the computer.

Next, when Chunyu walked into the room a few steps, he heard an electronic voice behind him, and the electronic voice prompted: "Fingerprint error!" ”

Chunyu can be sure that it is an electronic voice, an emotionless voice.

When he said this, Chunyu deliberately opened the electronic door in front of us and swiped the card with the back of his hand.

As a result, there was a loud screeching siren, and it didn't return to its original appearance until it was re-brushed with the palm of your hand.

Seeing this, I asked, "Wait, if you say that you make a mistake or your fingerprint doesn't recognize, it's all this kind of alarm, right?" ”

Chunyu nodded.

Phoenix said beside him: "But in the Ma Lili incident a year ago, there was an electronic prompt sound?" ”

Obviously, Chunyu's face showed a frightened look, but the other party still replied: "Yes, I heard it clearly at the time, it was the sound of the electronic prompt, but our system does not have the function of this prompt!" ”

After Chunyu finished speaking, he put the electronic door operation manual in front of us, and it was indeed written about the wrong fingerprint.

According to the manual, if there is an error, there will be the same screeching sound as before, but there will be no electronic prompt sound, and the alarm will not be discontinued until it is brushed again in the correct way.

I didn't understand and asked, "So, couldn't the voice come from somewhere else?" ”

Chunyu replied: "I don't know, when I came in, I felt that the temperature was much lower than outside, it was completely different from when I left here, I didn't pay that much attention, and when I looked back, there was no one behind me at all!" ”

At that time, the spring rain had already come to the gate, and it was very certain that he watched left and right for about a minute and a half, and it was certain that there was absolutely no one following him.

This is also certain from the current point of view.

The archives were originally built on the remote north side of the school, because the place was not accessible to outsiders and was not used often, so the construction sites were in places that students rarely passed.

Not far from the archives is a garbage dump, as well as an on-campus food processing site, and a flower bed.

Students rarely pass by here, and it's far from the off-campus gate, so it's hard to see why there's no reason to pass by if you don't have to.

On the other hand, the flower bed is directly opposite the archive room, but there is only one passage, you don't need to go out of the archive room, as long as you lean against the glass door next to it, you can see if anyone is passing by, it is easy to confirm.

Once, if someone was expected to follow or hide in the blind spots on the left and right of the glass door, it would be impossible to determine if the door would not be opened.

However, according to Chunyu himself, during the process of returning at that time, he did not notice that anyone was following.

As for where the electronic voice came from, there is no clue until now, and it has become a blind spot when the police investigate.

Let's put aside this issue for the time being, let's let that spring rain talk about the situation of the day, it would be better if we could be as detailed, what we need is the details.

Phoenix took out a notebook and waited for the other party to tell it again and again, while starting to record.

Go back and say a year ago.

Chunyu was also startled at that time, but after finding that there was no one outside the door, she began to call Ma Lili's name, but Ma Lili did not respond.

So Chunyu turned on all the lights up to the first floor, but at this time, he found that Ma Lili's shoes were still at the door.

In those days, if someone came in or out, they needed to change their shoes.

On the right side of the gate there is a shoe rack with slippers on it, and if someone enters must change into slippers here, put the shoes in the designated place at the door.
