Shu Yunwen complained in his heart, then pretended not to see the eyes of Nanatsuki Koshisui and turned his head to look at the building across the road.

Koshisui Nanatsuki was slightly stunned, and followed Shu Yunwen's gaze as well, only to see that the building across the road had obviously just been cleaned, and all the windows were clean and reflected in the sunlight.

Seeing this scene, Yueshui Nanatsuki was stunned for a moment, and then a flash of inspiration flashed in his mind, and his eyes lit up after a fist: "Yunwen, thank you for the reminder." I see, President Nakayama is using the reflection function of the mirror!"

Yueshui Nanatsuki's words fell, Shu Yunwen said "ha", and then looked confused-

Thank me? What are you thanking me for some reason? Have I said anything?

Also, what the hell is the reflection function of that mirror?

Shu Yunwen was confused, and Shiratori Ren Saburo looked at the surveillance camera on the roof of the building, and then looked at the window glass of the building across the road and said, "...... I see, the glass of the building opposite is so bright, and if you use a camera to look at the glass, it is possible to see the situation in the alley through the reflection of the glass......"

Before Shiratori Ren Saburo finished speaking, Nakayama Hidesei hurriedly defended: "Hey, don't be kidding, this is simply impossible! Please take a closer look, the picture seen through the reflection of the glass is blurry at all, and you can't see who it is at all, okay?"

Listening to Nakayama Hidesei's words, Tsukamoto Shumi, Koshisui Nanatsuki, and Shiratori turned their heads to look at Nakayama Hidesei together, and then only listened to Shiratori Ren Saburo's tone and said seriously:

"Really, President Nakayama, you really know about this, as if you have specifically checked it......

Nakayama Hidesei said "uh", and was so stunned by Shiratori Ren Saburo that he had nothing to say, while Koshisui Nanatsuki smiled slightly, looked at Nakayama Hidesei and said, "If it's through the glass of the building opposite, of course you can't see clearly...... But if it's through a shining mirror, then that's fine, right?"

“...... President Nakayama, I remember that in the logo on the body of your company's cleaning car, the eyes of the fish are a mirror, right? If I remember correctly, the cleaning truck was parked across the road at the time of the crime, and you removed it after the crime, right?"

"Uh...... This, this ......"

Nakayama Hidesei was directly exposed to the most critical modus operandi by Koshisui Nanatsuki, sweat broke out on his head, and he stammered and couldn't speak, while Koshisui Nanatsuki continued: "...... Also, the reason why you were able to pinpoint Director Fujii's location was that you put something in the alley where the iron fell, and something that was sure to attract him, right?"

Koshisui Nanatsuki's words fell, and Shiratori Renzaburo also said beside him, "We just found a harmonica with 'Fujii' written on it under the body of Director Fujii, and now we have handed it over to our colleagues in the forensic department to investigate......"

Under the "joint efforts" of Nanatsuki Koshisui and Ren Saburo Shiratori, Nakayama Hidesei finally couldn't resist, his head drooped down and sighed: "Okay, don't say it, I confess!"

When Nakayama Shuzheng's words fell, Aso Kaeri couldn't help but let out an "ah" and said in disbelief: "President Nakayama, is it really you? I remember, aren't you good friends who have been starting a business together since college?"

"Good friend, hehe......" Nakayama Hidesei smiled bitterly, and then his eyes were full of murderous intent, "...... You know what? It's this 'good friend' of mine who killed my sister!"

"What are you talking about?" Shumi Tsukamoto, Kaeri Aso, and Ren Saburo Shiratori were all stunned, and Nanatsuki Koshisui squinted slightly, "You should be talking about your sister's accidental death on the construction site, right?"

"That's right!" Nakayama Hidesei didn't expect Koshisui Nanatsuki to know about this, and after being slightly stunned, he gritted his teeth and said, "This Jiamanbao cleaning company was founded by me and my sister and that bastard Fujii, and my sister has been my secretary...... But two months ago, my sister suddenly had a big fight with me and left the company......"

“...... At that time, I always thought that my sister was thinking that I was too strict with her, but after my sister passed away in an accident on the construction site, I found out after helping my sister pack up her belongings and see her diary...... That bastard Fujii had been secretly dating my sister all along, and then after meeting a daughter-in-law, he dumped my sister...... It was also for this reason that my sister lost her mind at work and was accidentally ......."

When Nakayama Xiuzheng said this, his tone choked up for a moment, and then he said coldly:

“...... So, I'm going to kill Fujii, the bastard, and avenge my sister!As for the harmonica that Fujii pressed under him, it was a gift that my sister originally planned to give Fujii......"

"Hmm...... I see!"

After Nakayama Hidesei said this, everyone finally figured out the cause and effect, and Shiratori Ren Saburo walked up to Nakayama Hidesei and said, "Okay, President Nakayama." Let's go back to the Metropolitan Police Department for the rest of the matter!"

"Hmm...... Good. ”

Nakayama Xiuzheng nodded in frustration, while Shiratori Ren Saburo turned his head to look at Shu Yunwen and said, "Lord Yunwen, it's really thanks to you that we can solve the case so quickly......"

"Where, it's just a trivial matter!" Shu Yunwen smiled slightly, then stretched out his finger and pointed at Nanatsuki of Koshisui Dao, "Also, I just pointed out the murderer, if it weren't for the reasoning of detective Koshisui, President Nakayama might not have confessed honestly......"

In other words, he is really not good at reasoning, right?

If Nakayama Xiuzheng really didn't admit his guilt, he seemed to only use spells to scare him into confessing-

After all, we are civilized people, can we still be like the people of Sukishikai, who can't convince people with reason every day?

Shu Yunwen muttered in his heart, and Nanatsuki immediately said modestly: "Where, where! If it weren't for Yunwen-san, you reminding me to look in the mirror, I guess it would have been a long time before I thought of President Nakayama's tricks......"

"Uh......"

Why should I remind you to look in the mirror?

We just didn't want to pay attention to you at the beginning, and casually looked at the side?

How can you misunderstand that we are reminding you?

The corners of Shu Yunwen's mouth twitched, and he waved his hand and said, "...... Forget it......"

Whatever you want, it's good if you're happy anyway......

Shu Yunwen didn't bother to explain, but Shiratori Ren Saburo spoke again: "Okay, let's go downstairs first! Also, Lord Yunwen, do you have time later?"

"Huh, what's wrong?"

Shu Yunwen turned his head to look at Shiratori Ren Saburo, Shiratori Ren Saburo's eyes became resentful, and he said softly:

"Nothing...... I just have some personal matters that I want to talk to you about......"
