Conan: About the fact that I have a black brother

The wind is cold and the first snow has fallen in Nagano.

Lin Xiaochen and the other two had no intention of enjoying the snow. As the police car sped across the snowy sand, they could faintly hear the crunching sound of ice breaking.

Nagano Salin University.

Downstairs in the dormitory, security guards from the school’s security department had already set up a cordon, and the interwoven yellow and black lines foreshadowed the unrest inside.

Lin Xiaochen put on white investigation gloves, grabbed the cordon and went in.

Seeing the police coming, a middle-aged man in a security uniform stepped forward and said, "Mr. Police, you are finally here!"

"Who is the person who reported the case?" Yamato Gansuke asked in a rough voice.

Another young man in a down jacket stepped forward and said, "Mr. Officer, it's me. I'm Qingshu Wenshan, their counselor."

"Come with me." Yamato Gansuke signaled the counselor, "I'll go upstairs to confirm the details later."

Qingshu Wenshan responded quickly.

Lin Xiaochen nodded to the security captain: "Please take me to the crime scene. Please don't worry too much, we will solve it."

There was a bad smell in the dormitory. It was not the smell of a corpse, but more like the smell of food combined with the fact that the dormitory had not been ventilated for a long time.

The crime scene remained in its original state, with no other changes except that the bodies had been moved away.

Lin Xiaochen glanced around the room and asked the forensic doctor beside him: "Can the cause of death be confirmed?"

The forensic doctor pressed the bridge of his nose and tightened his mask. "None of the three deceased had obvious external injuries, but their faces looked painful, as if they had encountered something very cruel before they died. It could be poisoning, but I suspect it was sudden death."

"Sudden death?" Lin Xiaochen didn't understand. "What a coincidence, did all three of them die suddenly?"

The forensic doctor sighed helplessly, "I can't believe it either, but for now, it is true. We have to go back to the police station for inspection before we can say anything. Please pack up everything that can be imported and send it over."

Lin Xiaochen nodded in agreement.

Yui Uehara looked at one of the tables which was obviously tidier: "Is this the position of the sole survivor?"

Coincidentally, Yamato Gansuke came upstairs with the counselor.

Yui Uehara pointed to the table above the bed and asked, "Where is this classmate now?"

"She went out today. I have already notified her to come back immediately." The counselor wiped the cold sweat from his forehead.

"Doesn't she often stay in school?" Lin Xiaochen looked at the date, confirmed that today was Tuesday, and looked at the class schedule posted on the desk of bed number four.

"This student likes to study. She should have gone to the library after morning reading." The counselor followed Lin Xiaochen's gaze and said.

"How is their dormitory relationship?"

"There are some minor conflicts between them. It's mainly about their schedules. Qiuyueci, who is in bed number four, prefers to go to bed early and get up early so that her dormitory is quieter. The other three students like to play games or something like that."

The counselor pondered, "Qiuyue has a good personality. She mentioned changing dormitories before, but she couldn't find a suitable one, so she put it aside. But she also said before that her three roommates have gradually become quiet, so let's just forget about it."

Lin Xiaochen asked: "Can you repeat the process of reporting the case?"

"Of course, of course." Qingshu Wenshan said hurriedly, "The four of them are students of the medical school, so they have morning and evening self-study every day, and today is no exception. During the morning reading, three of them were absent, and the student committee couldn't contact them, so they told me. I called all three of them, but no one answered. Qiuyue was not in the dormitory, so I planned to go to the dormitory to check."

"I knocked on the door but no one answered, so I asked the dorm aunt to open the door with the key." Qingshu Wenshan recalled, "The dormitory was very dark and the curtains were drawn. Students are used to using curtains. After all, I am a man and it is not convenient for me to check. The dorm aunt opened the curtain of bed number one, which was Shangtang Sijia's bed, and found that she was lying there, so she pushed it..."

“Then,” he swallowed, “we found that the person was already cold, and we called the police right away.”

"Isn't this door unlocked with a card?" Uehara Yui checked the door lock. "Why does it need a key to open the door?"

"Ah, no, there is a snap on the door lock, and when you snap it open it becomes the keyhole." Aoki Onzan explained, "This is also to prevent the door lock from running out of power and causing students to be unable to return to the dormitory. This has happened before. The weather in Nagano is cold and the door locks are often frozen."

As he spoke, Aoki Onzan stepped forward and pointed at the door lock. Uehara Yui followed his instructions and successfully found the door lock.

"So, there are more than one way to enter the dormitory by swiping a card?" Lin Xiaochen asked, "Are all the keys to the dormitory in the hands of the dormitory manager?"

"That's the theory," the counselor replied. "Unless there are special circumstances, keys are not usually lent to students. Moreover, even if the door lock is out of power, the dormitory manager will come forward to help. After all, keys are easy to lose, and it is very troublesome if they are lost."

Yamato Gansuke immediately went downstairs to check the registration.

"Ah, Qiuyue sent a message saying that she was downstairs, but was stopped and not allowed in."

Lin Xiaochen immediately called the young policeman to bring the person up, and soon the sound of messy footsteps was heard.

The man was about 20 years old, about 165 cm tall and weighed about 100 catties. He was wearing a camel-colored turtleneck sweater, a long black down jacket, a cherry-red scarf, and a black backpack. He held a mobile phone in one hand and a plastic bag of cherry tomatoes in the other. He looked a little thin and seemed a little nervous when he saw the police.

"Teacher, I'm here... Mr. Policeman, what do you want to talk to me about? What happened?" Qiu Yueci's voice trembled slightly. She was slightly out of breath, not sure if it was because of the cold weather or because she walked too fast.

The only female police officer in the room, Yui Uehara, stepped forward to comfort him: "Don't be nervous, classmate. We'll just ask a few simple questions. It's a mess here. Can we go outside and talk?"

Qiu Yueci nodded and said stiffly, "Okay, okay."

Lin Xiaochen followed the two out the door.

Dormitory 823 where the crime occurred is at the corner of the building. Turning right after leaving the room, there is a floor-to-ceiling glass window, letting in bright sunlight. Lin Xiaochen observed that Qiu Yueci squinted her eyes comfortably and her breathing became much steadier.

Lin Xiaochen helped to find two chairs and put them away. Uehara Yui pulled Qiuyueci to sit down, and Lin Xiaochen stood on the side, just blocking the passage leading to this side.

Lin Xiaochen took out his phone and said to Qiu Yueci: "Student Qiu Yue, we need to record the whole process, please cooperate."

Qiu Yueci placed her hands on her knees, with the plastic bag leaning against her knees: "Okay, okay."

"Don't be nervous, little classmate. Just tell the truth." Uehara Yui smiled at Qiu Yueci, "Why don't you let this brother hold the little tomato and the schoolbag? It will be more comfortable to sit down."

Qiu Yueci pursed her lips: "Can I refuse? I feel safer holding it this way... Sorry, I'm a little nervous..."

"It's okay, don't worry too much." Uehara Yui patted the back of her hand soothingly, "Then shall we start now?"

Qiu Yueci nodded.
