I am in Kexue, and I start a blind date with my concubine Yingli.

Now.

Officer Twilight and many Metropolitan Police Department officers looked at each other, not knowing what to say.

When it was determined that Qin Beiyuan was suspected of major homicide, they were based on the confession of Uehara Shiyi's parents, the mobile phone photos in Uehara Shiyi, and Qin Beiyuan's alibi.

Nakajima forensic doctor said Shii Uehara was killed at 19-20 o'clock on Monday.

They investigated Qin Beiyuan's class schedule and Qin Beiyuan's community monitoring, but they didn't find that Qin Beiyuan had entered the community at all.

But now it seems that there are too many loopholes and coincidences in Shiyi Uehara's case.

"Qin Beiyuanjun, where did you go at 19-20 o'clock on Monday three days ago?"

Officer Twilight felt more and more that Qin Beiyuan was not the murderer, and said with a look of apology and curiosity

"We interviewed your colleagues and they all said you don't have any hobbies and usually go home after the course. "

"But why didn't you come home that day? What are you doing outside?".

Qin Beiyuan glanced at Officer Twilight, but in fact, Officer Twilight did not make a mistake in the investigation.

As an undercover agent of the Metropolitan Police Department to break into the black-clothed organization, he has always been very low-key, kind to others, and does not often participate in activities organized by Didan High School.

He finishes his course and usually goes home.

These twilight officers were right, but three days ago Monday night was different.

He suddenly received a message from the Black-Clad Organization asking him to meet, but when he arrived at the location, his original body was knocked with a black stick by tequila and thrown into the chemical factory.

Fortunately, Qin Beiyuan crossed in time and escaped death.

After escaping from the chemical plant, it was close to 19 o'clock in the evening at that time, but Qin Beiyuan did not go home, but went to Rice Flower Town Hospital and took a skull film.

After making sure that he had fully recovered from crossing the skull, he returned home and set up a situation against the black-clothed organization.

"Qin Beiyuanjun, can't you say it?".

Officer Mudui saw that Qin Beiyuan did not speak immediately, his eyes became more and more curious, and even a little suspicious.

"There's nothing you can't say!".

Qin Beiyuan said directly: "Three days ago, in the range of 19-20 o'clock on Monday night, I went to Rice Flower Town Hospital and took a CT of the skull!".

"I have a photo of the receipt of the hospital at that time, and at that time, there should have been surveillance cameras at the Rice Flower Town Hospital, so you can verify it yourself!"

"After I got out of the hospital, I went home and didn't enter the complex until 20:31 in the evening. "

Qin Beiyuan said as he showed the photo of the receipt slip on his phone to Officer Twilight and Kudo Shin.

The photo of the receipt sheet clearly shows the original consultation time of Qinbei, the doctor's name and other information.

Officer Twilight and Shinichi Kudo saw the photo of the receipt and were completely convinced.

Qin Beiyuan dared to take it out, which proved that he was not afraid of the Metropolitan Police Department to go to the hospital to investigate in person, and the receipt record recorded that Qin Beiyuan stayed in Rice Flower Town Hospital for nearly an hour and had no time to commit the crime at all.

"I'm sorry Qin Beiyuanjun, now I believe that you should not be the murderer of Uehara Shiyi. "

Officer Mudui sincerely apologized to Qin Beiyuan, Qin Beiyuan had a full alibi, and the possibility of being the murderer was very small.

"Teacher Qin Beiyuan, why did you go to take a skull CT that night?".

Kudo Shinichi was even more interested in the reason why Qin Beiyuan went to have a CT scan.

"Maybe there were too many classes, and my head hurt a little that night, so I just went to the hospital to get a CT shot!" Of course, Qin Beiyuan would not say that he would go out to meet the black-clothed organization.

"I see, Teacher Qin Beiyuan should pay attention to rest!".

Kudo Shinichi faintly felt that Qin Beiyuan was hiding very important information, but now that the case was clear, the possibility of Qin Beiyuan committing the crime was very small, and he couldn't ask anything more.

"But what does Qin Beiyuan mean when he said that the forensic doctor Nakajima misjudged the time of Uehara Shiyi's death?"

"Teacher Qin Beiyuan, you just conducted a detailed autopsy on the body, what do you think is the real time of death of the deceased Shiyi Uehara?".

Qin Beiyuan didn't hide it, and said directly: "The real time of death of the deceased Uehara Shiyi should be at 17-18 o'clock on Tuesday two days ago!".

"Two days ago Tuesday at 18 o'clock?".

Forensic doctor Nakajima looked at Qin Beiyuan incredulously and asked in surprise, "Did I misjudge so much? Why is this?".

"It may be that the temperature caused you to misjudge the time of Uehara's death. "

"In the last few days, the cold wave in Tokyo has worsened the temperature of corpses, and it is easy to make mistakes if you guess the time of death based solely on the cold temperature of corpses!"

Forensic doctor Nakajima suddenly realized when he heard this, and Qin Beiyuan continued:

"Forensic work is complex and scientific, and needs to be validated by many parties.

For example, to judge the time of death of the deceased, it is not only necessary to judge by the cold corpse, but also to test the stiffness, corpse spots, and the degree of pupil pollution, muscle reaction, and so on. "

"As far as the body of Shiyi above is concerned.

If the deceased had really died three days ago at around 19 o'clock in the evening, it would have been nearly 70 hours since then.

In the case of a corpse, if the corpse is left for 70 hours, the stiffness of the body should disappear and become loose and soft.

But you can touch Shiyi's corpse abdomen and biceps, and her corpse muscles are still stiff!".

"Of course, if you don't believe my autopsy inference, you can transport Shii Uehara's body to the forensic laboratory, and ask multiple forensic doctors and doctors to jointly conduct forensic and inference. "

Forensic Nakajima did not touch the body of Shiyi Uehara, and he was completely convinced.

There are no forensic doctors in the Metropolitan Police Department at all, and in terms of mastery of forensic science and autopsy, he thinks that no one is more skilled than Qin Beiyuan.

However, Kudo Shinichi still walked to the body of Shii Uehara and touched the deceased's abdomen with his hand.

Sure enough, the muscles in his abdomen were still stiff and inelastic.

Kudo Shinichi was secretly speechless, and his heart said that Qin Beiyuan was so powerful, and his mastery of forensic science was beyond his imagination.

"Shinichi Kudo, how do you feel, am I wrong?".

Qin Beiyuan really didn't expect that Kudo Shinichi would actually verify his autopsy and infer that this guy doesn't believe in evil.

"Teacher Qin Beiyuan's autopsy judgment is very accurate, there is no mistake!" Kudo Shinichi smiled at Qin Beiyuan.

It was at this time.

Among the teachers and students of Didan High School who were watching, a middle-aged man spoke up to Qin Beiyuan

"Teacher Qin Beiyuan, I remember if it's right, you didn't have any classes on Tuesday two days ago, and you left school at 17 o'clock, right?"

It was Nakamori Pingliang, the director of academic affairs at Didan High School, who seemed to be very clear about Qin Beiyuan's class schedule.

Wow-

At this moment, Officer Dusk's whole body was shocked, and he looked at Qin Beiyuan with wide eyes.

Kudo Shinichi also looked at Qin Beiyuan.

Qin Beiyuan deduced that the real time of death of the deceased Uehara Shiyi was in the range of 17-18 o'clock on Tuesday, two days ago.

So what did Qin Beiyuan, who left school at 17 o'clock on Tuesday, do?

Did he really leave school?
