Detective Conan: Knifeman? I'm a good citizen of Beihua

Deep in the archives room are gray compact cabinets.

The man with black hair and red eyes stood in front of the compact cabinet, quietly scanning the labels in front of him, with a deep darkness in his eyes.

"Host, why don't we check your files from back then, instead of coming here to look for some messy job records?"

The system is very incomprehensible.

"If there really was something fishy about the original owner's death, then his files and related materials would have been destroyed long ago. There's no way they would still be here."

The system was even more puzzled: "That's strange, host, why did you go to so much trouble to come here to investigate?"

Baichuan Qiu raised his head and finally saw a label, a faint smile appeared on his face.

"Everyone is focusing on my violation of discipline and the fact that I was expelled from school, but they've overlooked one thing—"

Baichuan Qiu reached out and opened the cabinet door, revealing a dusty file bag inside.

"The original owner was driving under the influence. As a police academy student, no matter how wealthy your family is, you're not allowed to drive your own car to the academy. So where did this car come from?"

Baichuan Qiu still remembers that after he woke up, no one ever mentioned the car at the scene of the accident to him. When he asked the relevant personnel afterwards, they just said that the car was seriously damaged and was towed away and destroyed.

According to the original owner's family situation and the memories of several of his friends, the original owner definitely did not have his own car.

That's strange. The original owner was driving someone else's car and ended up in a car accident with the driver dead. Afterwards, the owner of the car never showed up and didn't even ask Baichuan Qiu for an explanation?

So where did this car come from? It couldn't have been just someone walking down the street and grabbing one, right?

As soon as the original owner got into an accident, the school rushed out to expel him, as if they couldn't wait to nail Baichuan Qiu to the pillar of shame... Seeing such a guilty conscience, Baichuan Qiu couldn't help but suspect that the car accident was related to someone in the school.

And that car most likely belongs to someone else.

Inside the file bag was a thick record book containing the entry and exit records of vehicles at the police academy seven years ago.

Because of the long time and the low importance of the content, these records have been thrown here casually, and basically no one pays attention to them, let alone takes care of them.

When Baichuanqiu opened it, the booklet was filled with a heavy smell of dust and damp corruption.

He moved his nose and frowned uncomfortably, but his hands did not stop moving, and he searched all the way back to the day of the incident.

It was March 21st, the spring equinox of the cherry blossoms, the day when cherry blossom lovers pay homage to their ancestors and visit their graves.

Although the police academy has always been strictly managed and prohibits students from going out at night, on this special day, students can ask for leave to enter and exit the gate and go back to worship and sweep the graves.

There is no doubt that there are a lot of vehicles traveling back and forth these days.

But when Baichuan Qiu took a look, he found that the number of vehicles entering and leaving in the past few days was pitifully small, even less than in normal working days. This was obviously abnormal.

Baichuan Qiu lifted up the record book, touched the edge of the inner page, and indeed saw traces of paper being torn.

Judging from the traces, it should be quite old. I think that after the original owner had an accident, someone erased the vehicle entry and exit information of that day and forged a false information.

It seems that they are not stupid and know that they have to clean up the mess thoroughly.

The system also saw it, confused: "So this is a fake? What should we do then? Doesn't that mean that even this clue is broken?"

Baichuan Qiu flipped through the record book back and forth, scanning the contents on it for a long time without saying a word. Finally, he curled the corners of his mouth.

"No, it just proves my guess."

If he wasn't guilty, why would he deliberately disguise himself like this? Isn't it because he is afraid of being discovered to be abnormal?

The system was very frustrated: "But we can't be sure which cars went out that day."

“You can use the process of elimination.”

Bai Chuanqiu pointed to a record from March 20th. "For example, this one. The license plate number ends in 322, it's a black Honda, and the owner is noted as 'Zhongmu'. This car entered the school on the 20th, but there's no record of it leaving the school after that. Even after that, there's no record of it leaving the school—could it have entered the school and never left again?"

The system suddenly realized: "So he left on the 21st! Could it be him..."

Bai Chuanqiu shook his head: "I can't be sure. If I were them, I might even erase the record of this car entering the school."

The system was disappointed: "Then this is still useless, right?"

"But there are some places that can be verified indirectly." Baichuanqiu said.

"For example, some cars often came to the school before the 21st, but never appeared after the 21st. Or some cars still have the same license plate, but the next time they enter the school, they become a different car model..."

Baichuan Qiu gave many possible examples in one breath, which made the system dizzy.

"Of course, the worst-case scenario cannot be ruled out."

Bai Chuanqiu sighed and finally said, "If this car came to the school for the first time on that day, and all traces of it were erased afterwards, then everything I'm doing now would be in vain."

Upon hearing this, the system also became worried, but it also thought of a way it could help Bai Chuanqiu: "Host, I have recorded everything you read. I will rebuild a large data set later and see if I can filter out the suspicious guys based on the doubts you just mentioned."

Bai Chuanqiu raised his eyebrows slightly: "Not bad, system, you finally made me feel that you have some value in existence."

System: "I have always wanted to help the host!"

Just as the two were talking, footsteps were heard behind them.

Baichuan Qiu's expression froze, and he stuffed the things back intact. Then he hid his body and stuck to the gap in the cabinet to hide himself.

After a sound of footsteps, a person stopped at the same place where Baichuan Qiu had just stood.

The system's voice trembled: "Oh no, host, you must have been discovered!"

Baichuan Qiu narrowed his eyes and held his breath: "Probably not."

The other person seemed to be holding a flashlight, and the light of the flashlight was almost next to Baichuan Qiu's cheek, and he could see him clearly at any time. Baichuan Qiu leaned back slightly, trying to keep a distance from the light.

After a while of rustling, the other party also opened the cabinet and took out the record book that Baichuan Qiu had just put back.

The system screamed, "He's here for the record book too! What should I do? What should I do..."

Bai Chuanqiu stopped the system in a deep voice: "Quiet, your voice is affecting my auditory judgment."

The system immediately quieted down.

In front of Shirakawa Akane, Matsuda Jinpei frowned, bit the flashlight, and rubbed the torn pages with his hand, with a cold look in his eyes.

Sure enough, there was something fishy about what happened seven years ago!

He decisively took out his cell phone, quickly flipped through the record book, and recorded everything on it.

Jinpei Matsuda was very fast. In less than two minutes, he completed a series of actions, put the things back into the file bag, put them back in their original place, and closed the cabinet door.

"Snapped--"

The closing of the cabinet door raised another layer of dust. Matsuda Jinpei held the cabinet door with one hand and put his cell phone back in his pocket with the other. He wanted to take the flashlight out of his mouth, but suddenly stopped.

It was obvious that this place had not been cleaned for a long time, and even the cabinet was covered with a thick layer of dust. But what was worrying was that on the cabinet door that Matsuda Jinpei pressed, in addition to the place where his hand was placed, there was also a handprint on the diagonal side that almost overlapped with it.

The handprint was not particularly obvious, and it looked like there was still a lot of dust on it, but Matsuda Jinpei carefully observed the internal handle of the cabinet door and found that the dust inside had disappeared. It was obvious that it had been opened not long ago, otherwise there would definitely not be so little dust.

Suddenly, Matsuda Jinpei thought of this strange time bomb mission——

His eyes suddenly became sharp——

Just now, there was someone here!

He might still be here!
