Conan: About the fact that I have a black brother

"Do you have any good classmates?" Uehara Yui closed the book and returned it to her. "We need to find them to find out something else."

"There are several." Qiu Yueci said, "Do you need me to provide their names?"

"That couldn't be better." said Uehara Yui.

Qiu Yueci said a few names and classes, and Uehara Yui wrote them down one by one and showed them to Qiu Yueci, who nodded in confirmation.

Lin Xiaochen changed his hand and held up his phone: "Student Qiuyue, we need you to provide some social software information. Is this convenient for you?"

"How to provide it?" Qiuyueci asked.

"Can you show us your phone?"

"Of course." Qiu Yueci handed the phone to Uehara Yui, "The password is a five-pointed star pattern."

In fact, it doesn't need to be so troublesome. As long as the police want, they can retrieve all Qiuyueci's online information at any time. However, Lin Xiaochen still wants to test the other party.

Seeing Qiuyueci's calm attitude, Lin Xiaochen didn't say anything more.

"Can I ask one more question? How long will it take for this phone to be returned to me?" Qiu Yueci asked uneasily when she saw Uehara Yui putting the phone into the evidence bag. "I may need to do homework or something."

"It's okay. We will return the data to you after we copy it." Lin Xiaochen said, "I will return the phone probably this afternoon."

"Ok."

Lin Xiaochen: "Can you come back to the police station with us later to provide fingerprint information?"

Qiu Yueci cooperated very well and agreed: "Mr. Policeman, where should I live during this period? I'm a little scared."

"Don't be afraid, we will arrange it for you, it's okay." Uehara Yui returned the plastic bag to Qiu Yueci, "Be careful with everything you bring in during this period."

"Okay, thank you, sis."

Qiu Yueci followed Lin Xiaochen and his group back to the police station, and was questioned again after providing fingerprints and blood information. Her answers were exactly the same as when she was at school just now. After staying for lunch, Lin Xiaochen returned her phone to her and sent her back to school.

The police began an intensive investigation.

In the office, Yamato Gansuke swallowed the rice ball and clicked on the interface displayed on the computer.

"This Qiu Yueci is not as well-behaved as she appears to be." Yamato Ganzhu pointed at the chat records between Qiu Yueci and his classmates, which were full of complaints about her roommates. "The insults were pretty harsh."

"It's normal to have a few complaints in your heart." Uehara Yui had a good impression of Qiu Yueci and walked over to take a look. "According to the counselor, Qiu Yueci has never taken the initiative to cause trouble. Even if she is not so harmless, it is not a big problem."

"That's true." Yamato Gansuke nodded.

Lin Xiaochen brought the newly investigated information about the deceased: "I don't think Qiu Yueci is necessarily the first suspect, you see."

The remaining two people went over.

"Bed number one's Shangtang Sijia is a delinquent, bed number two's Shuiyue Yanxiao is engaged in body trade outside, has had physical relationships with many men and has had abortions, bed number three's Murakami Qiuyi's family is involved in gambling." Yamato Ganzhu sneered, "Indeed, compared to this, Qiuyue Ci is considered honest."

"Moreover, Qiu Yueci took part in the national civil service examination. Although she was not selected due to poor physical test results, she passed the political review, so there is no problem with her." Uehara Yuiko added.

"But the child is quite stubborn. There are many photos of the house being cleaned up, probably to keep as evidence. There are also several recordings and screenshots of noise. Nearly 90 decibels of noise at night can really drive people crazy. Qiuyueci's request for quiet is not excessive." Lin Xiaochen commented, "90 decibels at night, if it happened in the community, we would call the police."

Lin Xiaochen thought of the messy and dirty toilet and couldn't help feeling disgusted: "Qiu Yueci didn't clean it, and they really didn't even touch the mop."

"Qiu Yueci's life is very stable. She goes to school during the day, runs at night, and goes to the gym and the park for walks and shopping on weekends. She has been like this since the beginning of the semester, and there is nothing unusual." Yamato dared to help her in a sigh of relief, "She has a healthy schedule. Judging from the websites she browses, she probably wants to take another exam. I don't believe that a person like her will leave a stain on her resume."

Zhu Fu Gaoming came in with the forensic autopsy report: "The poison is a rare compound poison. The forensic doctor found five lethal agents and three chronic poisons in the water dispenser."

"It seems that the murderer hates those three people. It's too cruel." Lin Xiaochen exclaimed in amazement.

"That's true," Zhu Fu Gaoming recalled Qiu Yueci's expertise and said, "But the three bodies did not show any signs of poisoning, so the cause of death was not poisoning."

Lin Xiaochen couldn't help but sigh.

Yamato Gansuke asked, "Have you checked the records of drug requests from the laboratory?"

Uehara Yui continued: "We have checked everything. Qiu Yueci has no record of claiming the benefits. We have also checked the interpersonal relationships of other recipients. Qiu Yueci does not know them, and they have no contact with the three deceased persons."

"He's just a poor student who was innocently involved." Uehara Yui took a breath and sighed in her heart, "A few friends of Qiu Yueci took it over. I'll go over and take a look."

"I'll go too." Lin Xiaochen suggested, and Uehara Yui nodded.

Several little girls from different classes sat on the sofa somewhat awkwardly.

When Uehara Yui walked over, a few people stood up and wanted to say hello, but Uehara Yui stopped them and said, "Just be casual, let's just chat."

"How is your relationship with Qiuyue?"

"It's pretty good." "We get along well." "It's pretty harmonious."

The girls chirped.

"So...what kind of person do you think Qiuyue is?"

"Emm, Qiuyue has a good personality, she is very sunny and cheerful, she is very kind and will help me with everything." A little girl with thick eyebrows and big eyes, her personality is also very straightforward, "She is a warm-hearted person, she gave me medicine when I was sick before, and she would share her delicious food with me as soon as possible."

"Yes, she helped take care of me last time I had a heat stroke." Another girl with her hair down said, "She and I live in the same place, and I feel like she knows a lot more than I do."

"She is very outgoing..." said a girl. "She likes to go out for a walk, unlike me who likes to stay in the dormitory..."

"It sounds like Qiuyue is quite popular... Are you and her classmates in the same class?"

Two or three students nodded, while the others shook their heads.

Yui Uehara looked at the three girls sitting together and asked, "How popular is Akizuki in the class?"

The three girls hesitated, and a girl wearing glasses said softly: "She... is okay..."

Uehara Yui looked suspicious: "Really? But Qiuyue herself said that there are few people in the class she can talk to. She told me that you three are the only ones she can talk to."

Uehara Yui glanced at Lin Xiaochen, who understood and said sternly, “Hey, classmate Hiyori Ryoko, please don’t lie to us.”

"She... is fine..." Her voice trailed off, "After she had a falling out with her roommate, that's all she is..."

Lin Xiaochen frowned: "What do you mean by just like that?"

"I……"

Uehara Yui: "Hayasi, don't scare them. If you are not comfortable talking here, you can stay and tell me later."

Of the remaining two students, one said that he was Qiu Yueci's deskmate during the morning reading class, and the other said that he was Qiu Yueci's partner in the experiment. Both of them felt that Qiu Yueci was a very reliable person.

Yui Uehara asked someone to send them back to school.
