On Sunday, Qianjun got up early, rushed to Ali's house and woke up Dr. Ali. Dr. turned over and said, "Let me sleep for a while, I'm so sleepy..." Qianjun pulled him up angrily, "Please, Doctor, don't you be so lazy? Your physical condition is a bit too standard. Didn't the doctor suggest you get up in the morning and run and exercise? Really, you don't answer my phone number, and you also want me to come and wake you up..." The doctor had to get up slowly, and after getting ready, he went out with Qianjun.

On the way, the doctor was panting, "Qianjun, I can't run anymore, let's get here today..." Qianjun was funny, "Doctor, you really need to exercise well, you have only run for such a short period! It seems that someone swore yesterday that he would stick to 2 kilometers and live for more than 20 years every day, and he also pulled me up to supervise to show his determination..." Dr. Agasa regretted that his intestines were blushed, "I did think so yesterday, but I didn't expect to be so tired, it's really impossible..." "Doctor, men must be able to do it, let alone you are not 60 years old!"

At 7 o'clock, Qianjun pulled the doctor to jog. Not far away, Xiaolan and Conan ran over. Xiaolan turned around and urged, "Dad, are you okay?" Conan smiled, "Uncle is tired of running!" Maori Kogoro ran over shakingly, "What's this? I'm not awake!" Qianjun and the doctor came over to meet Xiaolan and Conan, and then they realized that they were also here to run and exercise. "Uncle Maori said he was going to run!" Xiaolan tidied up his hair in front of the fish-eye mirror cleaning the car next to him, "Yes, we are here to run with my dad!"

Kogoro arrived panting, his condition was just as good as the doctor. "Let me take a break!" Xiaolan pushed Maori from behind, "Look soon, there are still 2 kilometers to the park..." Conan turned around and shouted, "Doctor, come too, you need to work out too!" The doctor's face turned green, "Well, do I want to go too?" Qianjun pushed him, "Let's go, it's good to exercise more, come to my place for breakfast when I go back, Jingyang and the others should prepare breakfast, you will like it very much." The doctor swallowed, "I want to go to dinner now..." Qianjun and Conan Khan.

While everyone was talking, a cold man in a nearby building lit a photo of two men and one woman. A young man came over in the fire protection alley next to him and bent down to pick up the harmonica on the ground. A heavy object suddenly fell off the upstairs and smashed him to death on the spot. The screams made by the deceased before his death scared the five people running. Everyone ran to the opposite fire protection alley to check. Xiaolan let out a high decibel scream, Qianjun was speechless, "That's true, it's not the first time I have seen a dead person with your father and Conan. It's so exaggerated!" Conan sweated on his head, "Hey..."

Maori stepped forward and observed carefully. The cleaners who heard the screams nearby also rushed over. The cold man on the upper floor put down his telescope and asked his female secretary to go downstairs to see what happened. The secretary agreed. Kogoro had finished checking and shook his head, "He is dead, it seems that he was killed by an iron plate that fell from above." The cleaning workers claimed to be employees of the Jie Ou Cleaning Company, the building opposite. They were all wearing unique clothes and a big fish sign on it, which was even on the cleaning car. Maori asked the cleaners A, B and C to go to the abandoned roof to see if anyone pushed the iron plate down. The three agreed and left hurriedly.

Kogoro asked Qianjun to run around the entrance opposite the fire protection lane, blocking it, and preventing outsiders from entering. Maori personally blocked everyone here and protected the scene, and ordered Xiaolan to call the police immediately. The doctor complained that this happened early in the morning. The female secretary came downstairs and recognized the deceased as the director of their company's business, Tomohisa Fujii, and also a director of Jeho Cleaning Company. The female secretary in red is named Kuriko Mamu, 31 years old, with a medium-sized appearance and looks very capable. Maori judged that Fujii passed through this corridor when he came to the company building from the opposite business office to the company. Mamu also said that Fujii had made an appointment to meet the president at 9 am this morning.

At this time, Hideo Zhongshan from Jeho Cleaning Company came over and asked about the situation. Hideo Zhongshan was 29 years old, with a darker complexion, similar to Hattori Heiji and Chikuru Fuliang, and had a sharp look on his body. After Zhongshan asked about the situation, he instructed Ms. Mamu to ask the employees to immediately move the cleaning car across the street and not to hinder the police from handling the case. Mamu agreed and hurriedly ran to notify the employees.

Officer Memu led his assistant police officer and others to the scene for a preliminary investigation. Maori and the cleaning staff arrived at the abandoned building next door, but no suspicious figures were found. Then everyone went to the president's office of the cleaning company, and the police were preparing to ask everyone about the relevant questions. When the case occurred, Nakayama Hidezen was in the room, and Mami Kuri was also in the secretary's room next door. Detective Maori believed that the iron plate should have fallen from the roof of the building. Officer Memu also found out that the 1-2 floors of the building were rented to Jeho Cleaning Company, and the above 3 floors still belong to the company where the owner is located.

The building administrator said that since today is Sunday, no one from other companies went to work, except for Zhongshan and Mamu, there was no one else in the building. Zhongshan Hidezheng smiled bitterly, "Then we two are not there to prove it, it's really a headache!" Mamu Kurenko also admitted that there was indeed no one to prove it, and they could only testify for each other.

Conan found a remote control on his desk in Zhongshan, with a rocker and a switch on it, and it was divided into manual and automatic. Conan also found a surveillance screen that could see the situation on the road. Qianjun judged that the camera should be installed on the roof. The doctor smiled and said, "You see the angle of the surveillance screen is constantly changing. The camera automatically adjusts the angle, and the remote control should control the camera."

Conan was planning to play with this remote control, but Xiaolan found out and scolded him, "Conan, how can you touch someone's things at will!" Conan had to let go angrily. Kogoro found a photo of a young woman on the table and asked with a smile, "Is this Mrs. Zhongshan?" Hidemasato Nakayama shook his head, "No, this is a sister, Kumiko Nakayama. However, she passed away in January this year." Kogoro hurriedly apologized, and then praised, "Mr. Zhongshan became the president when he was young, which is really amazing!" Zhongshan smiled and talked about entrepreneurship.

It turned out that this cleaning company was founded by Hidezen Zhongshan during his university years. Kumiko and Fujii were also involved in the entrepreneurship together. They started operating in a variety of company forms. None of them expected that the company would be widely praised. Two years later, they concentrated their business on cleaning and officially established this Jeho Cleaning Company. Hidezen Zhongshan served as president, and Hoku Fujii was responsible for on-site surveillance and also served as the director of Toto's business. Kumiko Nakayama served as secretary, but died this year, and later, Kuriko Mami was secretary.

Zhongshan admitted that he had a conflict with senior Fujii recently because Fujii wanted to withdraw from the company and started a new cleaning company. Fujii also planned to take away several excellent cleaning staff from the company, so the two had a fierce dispute. Today, Fujii also came to argue with Zhongshan about this matter.

Detective Maori immediately shouted, "I understand!" Meguru Khan, "It's too fast!" Kogoro thought that Hidezei of Nakayama pushed the iron plate from the roof and smashed Fujii to death. "Because Miss Mamu and Mr. Nakayama are boyfriend and girlfriend, Miss Mamu will perjure Mr. Nakayama!" Nakayama and Mamu laughed, and Kogoro was angry, "Is there anything wrong with what I said? The president and female secretary usually have this kind of relationship!" Everyone sweated on their heads, and Mamu Kurenko smiled, "How can you say we are boyfriend and girlfriend!" President Zhongshan also smiled, "I'm very sorry, Mr. Maori's reasoning was wrong. Because Miss Mamu already has a master, she will get married and be a bride next month."

Kogoro was stunned, "Bride..." Officer Memu sighed, "I knew it would be like this!" At this time, the forensic and assistant police officer came in to report and found traces of the friction of the iron blocks in the abandoned building next door. This also confirmed that the iron blocks were indeed smashed from the roof. A harmonica was also found at the murder scene, with a name on it, which the police believed was Fujii's thing. Hidezen Nakayama also recognized that the harmonica was Fujii, and Fujii played music with the harmonica many times. What the forensic staff was confused was that there was no fingerprint on the harmonica, as if it had been wiped by someone.

Everyone was shocked. If Fujii was holding it in his hand, there should be fingerprints. Officer Memu asked Maori and Qianjun whether anyone had entered the fire alley after the incident? Both of them said that they did not. They guarded the two entrances respectively and did not let anyone in. Nakayama suddenly asked something and wanted to go out. Officer Memu nodded, asking him to go first, but he would cooperate with the investigation later. Nakayama got up and left, and when he left, he reminded Miss Mamu to notify Fujii's parents and fiancée of this unfortunate thing. Nakayama nodded and agreed.

Qianjun was curious, "Does Fujii already have a fiancée?" Mamu nodded, "Yes, it's still the daughter of an entrepreneur! I heard that the start-up funds for his new company were sponsored by the lady's father." Conan asked, "How did Miss Zhongshan die?" Mamu said, "It was because of an accident that she had a big fight with the president in December last year and left the company. Later, I came to the company. Not long after, I heard that Kumiko was working at a construction site in Yokohama. In January this year, she accidentally hit the head and died."

Everyone was surprised. Officer Megu asked again, "Is this the same as today's accident?" Mami Kurenko nodded, "Yes, because I think it's too coincidental, so I think it's too terrible." Conan and Qianjun shook their heads together. Both of them thought it was not a coincidence, but they were afraid that this incident would have some connection with Nakayama Kumiko's death. "If this is the case, this president would be very suspicious." "But, how did he do it?"

Officer Meguri decided to ask the employees of the abandoned building opposite and let everyone stay here for the time being. Conan believed that the problem was still on the automatic camera, so he deliberately reminded Detective Maori to see the road from the screen. Mamu Hiroko explained that the surveillance camera was installed on the roof because the president hoped that the road in front of the company could be kept clean, so he often watched the road conditions through the monitor. Detective Maori was very impressed by President Nakayama's idea. He smiled and said, "Our president's ideas are very novel. For example, cleaning cars are usually parked in front of the company's building, which has indeed achieved good publicity effects."

Conan was curious, "If the switch is replaced with manual control, can you see the road situation?" Conan smiled numbly and asked Conan to try it himself. It turned out that he could not see it at all. Conan was a little depressed and opened the drawer and found the telescope. Xiaolan was angry and criticized Conan for how he could open someone's drawer at will? Conan wiped his sweat, changed the topic, and asked Qianjun to check it out together on the roof.

The camera on the roof was very large, and the abandoned building opposite the fire protection lane was lower than here. The two also found the mark of friction between the iron plates of the abandoned building. Conan believed that, "Even if you can jump over this height and push the iron plate down, you can't jump back afterwards." Qianjun looked at it, "Nonsense, you can jump back. If it really doesn't work, you can easily achieve it with some tools, such as horizontal ladders and ropes..." Conan had a headache, "You are an abnormal exception. If you want to use tools, it's too risky and it's easy to leave traces. The murderer shouldn't be that stupid."

Qianjun frowned, "According to your analysis, Hidezheng Zhongshan could not push the iron block down, and he was indeed in the president's office when an accident happened, and that numb lady could testify." Conan was speechless, not knowing what Zhongshan had used. At this time, the camera suddenly rotated. Conan was stunned and suddenly understood something, and asked Qianjun to carry him to the wall to watch. Sure enough, he found traces of steel wire pulling, and it was a new injury. Conan looked below the camera again and smiled. He knew the method Zhongshan took.

"But how did he know that Fujii must pass there?" Conan looked up and found that the glass opposite was very bright, reflecting the situation here. Conan ran back to the president's office and found that the building opposite was covered by things and could not be illuminated with the situation in the stairs. Qianjun asked in confusion, "What's going on with that harmonica?" Conan suddenly realized that it was not using the reflection of the building opposite, but the harmonica and fish eyes, so there were no fingerprints on the harmonica.

Officer Memu came back dejectedly. When the workers had wiped the glass of the building opposite when the incident happened, they ran to rest, so they didn't see anything. Dr. Agasa rewindled and Conan smiled. The evidence was here, and the doctor was a little puzzled. Hidezeki Nakayama also rushed back. Officer Memu decided to be here today and disturb him another day. Qianjun hurriedly stopped him, and Memu asked angrily, "Do you know the truth?" Qianjun shook his head with a wry smile. Memu snorted and planned to withdraw the team and leave. Conan thought it was not good. If he left at this time, the evidence would be cleaned. So, the sleeping Kogoro appeared.

Officer Memu asked what the hell was about Maori. Detective Maori said, "You can't go back now because I already know the way of President Zhongshan killing Mr. Fujii in this room." Officer Memu was very surprised, "What did you say? Is the murderer the President Zhongshan?" Detective Maori nodded, "The focus of his technique is on the camera upstairs."

Kogoro explained the murderer's method. President Zhongshan first put the iron plate on the abandoned roof, and then tied the surveillance camera on the roof with some thin wire, which should be a steel wire, and tied the camera and iron plate to control it. Then when Mr. Fujii passed the fire protection lane, he remotely controlled the camera on the roof, changed it to manual operation, used a rotating camera to pull the steel wire, pulled the iron plate and fell down, smashing Fujii to death. Afterwards, President Zhongshan deliberately asked Miss Mamu to go downstairs to inquire about the situation, and he took the opportunity to go to the roof to retract the steel wire. Zhongshan said not long ago that he had something to leave and that steel wire should be dealt with.

Detective Maori asked, "Mr. Zhongshan, I'm not wrong, right?" Nakayama sweated. "Whether it is right or wrong, the reasoning lacks an important part. When Mr. Fujii arrived at the Fire Protection Alley, I was in the office. How did I kill senior Fujii?" Officer Memu also believed that "the timing should be a second deviation, and the iron plate would not hit Fujii's head." Qianjun smiled, "I know this. Mr. Zhongshan used Fujii's harmonica. He put the harmonica in advance in the fire protection alley." Detective Maori continued, "He saw Mr. Fujii walking into the fire protection alley with a telescope. He saw through the reflection of the company's cleaning car. The eyes with fish patterns on the car were a mirror."

Zhongshan saw Fujii's movements through the reflection of the telescope and the mirror of the cleaning car, so afterwards, he hurriedly asked Miss Mamu to inform the employee to drive away the cleaning car, so that the police would not see this method. However, Zhongshan made a mistake, which was to throw the iron plate down before Fujii picked up the harmonica, so there was no Fujii's fingerprint on the harmonica.

"You are too anxious. You can't actually blame you, because at the most critical moment, Xiaolan blocked the mirror to tidy up her hair..." Seeing that the matter was exposed, Nakayama struggled to death, and asked Detective Maori to come up with evidence. Maori sneered, "Of course I have evidence. After you moved the camera and let the iron plate fall down, you changed the direction of the camera, so that it would be easier to remove the steel wire on the camera, but at this time the camera took the scene mapped on the glass window opposite. Dr. Agasa, please, pour the belt back..."

Dr. Agasa Zheng pointed out, and went over to operate and set the time to 7:05. Next, everyone saw the glass-contact scene on the screen. The whole process of Sun Yat-sen Hide-sen taking the tightrope under the camera. Now the evidence is as strong as a mountain, and no longer allowed to quibble. Sun Yat-sen Hide-sen sighed and admitted his crime.

It turned out that the relationship between the brothers and sisters of Zhongshan was very good, and their parents passed away very early. Hidezeki Nakayama loved her sister very much, and the brother and sister depended on each other for their own life. Kumiko Nakayama and Hokuhiko Fujii became a couple, but later Fujii chose the entrepreneur's daughter for the sake of her career and abandoned Kumiko. Kumiko was sad and quit her job in the company and went to Yokohama to work, and died unexpectedly. When Hidezeki Nakayama was sorting out her sister's relics, she learned that her sister had secretly been with Fujii without knowing the truth. After learning the truth, Hidezeki Nakayama was very angry and carefully planned the murder.

"However, it's really funny. I want to use the fish eyes of the cleaning car as a mirror. Unexpectedly, the glass window opposite also shines my shadow, confirming all the crimes I committed." Zhongshan was a little sad, and Officer Memu sarcastically said, "And the person who wiped the glass of that building spotlessly was either someone else, or your company." Zhongshan showed a confident smile, "Of course, the cleaning technology of our Jeol Cleaning Company is originally the best in the world." Officer Memu waved his hand, and the police officers under his command stepped forward to take Zhongshan away.

After Kogoro woke up, he was a little confused. Qianjun had to remind him of the final result of the case. Maori nodded, "It seems that I solved a difficult case unknowingly. Strange, why don't I have any impression of it? Do I have schizophrenia?" Everyone looked dark, and Xiaolan blamed him, "It must be that you usually drink too much, and you have mild alcohol poisoning, which has caused forgetfulness..." Conan was funny and said to himself, "It's not poisoning, but anesthesia injection."

Then, the Maori trio went home, and Qianjun and the doctor also said goodbye to Qianjun's residence. Jingyang and the others had already prepared breakfast and had been waiting for a long time. At the dinner table, the doctor was greedy. If Dr. Qianjun continued like this, his physical condition would be beyond the standard. Jingyang asked why it was so long. Qianjun explained the Maori Detective's reasoning case in detail. Jingyang exclaimed, "Detective Maori will encounter murder cases even when he went out to run!" Naoko sighed, "I didn't expect that Xiaolan's actions in looking in the mirror made the murderer reveal a flaw!" Xiaoya praised, "Is Conan really only 7 years old? How does Kogoro teach him usually? Knowing so many things is better than Qianjun!" Qianjun said intimately, "That's Shinichi Kudo, of course he is better than me!"

At the end, Hidezen Nakayama was sentenced to five years in prison by the court for killing Fujii Hokuro. Kogoro Mouri cracked the case of a cleaning car murder, and the Metropolitan Police Department gave him a B-level reward. A few days later, one evening, Xiaolan and Conan came back from buying vegetables and saw the cleaning car of Jeo Company. Conan did not expect that the president of their company was arrested and imprisoned and the company continued to operate. Xiaolan heard that his secretary Mami Kurenko was hit and resigned, "Maybe it was too exciting, and I don't know what she was doing now." At this time, Mami Kurenko's speech appeared on the TV screen on the street. She had become an assistant to Jaeo Company and temporarily managed all the company's business. Both of them were surprised, and Conan sighed, "This Mami Miss is really amazing!"
