The Xindu Police Headquarters building has a state-of-the-art, spacious and diverse canteen, where officers from various departments will eat at lunchtime.

At Chen Chuyao's suggestion, Li Andi changed his previous habit of eating special lunches and also came to the canteen of the police headquarters to eat.

Previously, the reason why Li Andi did so was completely because of his living habits, and he didn't expect to cause dissatisfaction among other colleagues, given that Li Andi has always ignored the hostility and complaints of his colleagues, and he never noticed that there was anything wrong with his behavior.

As for the leaders of the Pre-Search Section 1, they have always been resigned to the chaebol noble son personally arranged by the director of the National Police Agency, and only begged this prince not to do anything that endangers everyone's interests and safety.

It wasn't until Chen Chuyao's kind reminder that Li Andi realized that his habitual habits had caused trouble to others. So, he immediately followed Chen Chuyao's advice and began to eat in the cafeteria with her. At the same time, he will try to avoid behaviors that may cause dissatisfaction among his colleagues, but these are mostly in vain, because colleagues who know him have already formed a preconceived impression and will not change because his behavior has become low-key.

On this day, Chen Chuyao and Li Andi came to the cafeteria for lunch, and the two of them each ordered their favorite meal, and then chose a quiet seat to sit opposite each other.

Because Chen Chuyao and Li Andi are partners, the pair did not attract too much attention, except for the pre-search of those single young men in Section 1 and the unmarried young girls who coveted Li Andi from the police headquarters would cast resentful eyes from time to time, and nothing unexpected happened.

"Chu Yao really likes Western food!" Li Andi looked at Chen Chuyao's lunch and said with a smile.

After cooperating with several cases, the two have a tacit understanding enough, and they talk like friends for many years.

Chen Chuyao found that Li Andi usually pretends to be profound and rejects people thousands of miles away, but in fact, he has a slight social barrier, and in front of unfamiliar or his superiors and elders, he will involuntarily show an overly serious and serious appearance, giving people the feeling that it is not easy to get close, and Li Andi will behave much more cordial and natural in front of familiar people.

"I prefer a vegetable salad!" Chen Chuyao also smiled and said, "Andy, do you want to taste it?" ”

Andy Li looked down at his beef noodles, and then nodded, "I'm going to buy a vegetable salad too!" ”

After that, Li Andi got up and went to the window selling Western food to line up again, leaving Chen Chuyao to stop talking, not knowing whether to explain or not, she meant to let him taste her salad.

Seeing the resolute Andy Li leave, Chen Chuyao finally didn't say anything to stop him, so he had to wait silently for him to come back and dine together.

After a while, Li Andi sat back opposite Chen Chuyao with the same vegetable salad.

Chen Chuyao looked at Li Andi with a little jerky and smiled.

"Why haven't you eaten yet, it's cold for a while!"

Li Andy looked at the food in front of Chen Chuyao that had not yet moved, and asked in some surprise.

"Waiting for you!"

Chen Chuyao said with a chuckle, that smile was bright and flawless.

"Oh!" Li Andi nodded with a smile and said, "Eat it!" ”

So, the two began to eat.

"Chu Yao, about the matter of Shenyin and the Shadow Man, I have asked the relevant people to collect information." Li Andi suddenly said to Chen Chuyao: "Maybe from similar cases in the past, we can find some breakthroughs." ”

When Chen Chuyao heard this, she looked up at Li Andi, her eyes showing gratitude.

"Thank you, Andy!" Chen Chuyao said softly.

Li Andi was slightly stunned, and then said softly: "This is also what I want to do, Chu Yao doesn't have to be polite." ”

"The previous unsolved cases should be confidential, and I'm afraid it will not be easy to investigate!" Chen Chuyao said worriedly.

"Indeed!" Andy Li sighed: "The gentleman I asked said the same thing. ”

"Andy, please don't use those unconventional means this time!" Chen Chuyao said solemnly: "After all, it involves the police headquarters and even the police department, and may even involve powerful and high-ranking officials." ”

"Chu Yao, don't worry!" Andy Li also replied solemnly: "This time, I must make the process and form reasonable." ”

Chen Chuyao smiled with satisfaction when she heard this, "That's good!" ”

"Chu Yao, don't you ask me what I'm going to do?"

"I believe in Andy's abilities and guarantees!" Chen Chuyao smiled and said, "Let's eat first!" ”

"Good!" Andy Lee also smiled and responded......

On October 5, 2451 A.D., the office of the 1st Section was pre-searched

Section Chief John Gao convened all the members of the Pre-Search Section 1 to hold a meeting to discuss the case.

"Presumably everyone has heard that Sheng Jingfeng, chairman of Shengshi Group, was killed on September 25." Section Chief John Gao said clearly: "Up to now, the police headquarters has not received an early warning of the crime index, and the detection of the case has also fallen into a bottleneck, and the incident has become an unsolved case." ”

"Our Pre-Search Section 1 and other relevant departments of the Police Headquarters will intervene in the investigation as soon as possible!" Deputy Section Chief Su Fang then added: "But all the parties in the case have alibi! ”

"To be exact, the scene of the crime is a secret room!" John Gao followed.

"Not only did they successfully circumvent the surveillance of super artificial intelligence, but they also created a locked room murder?"

"It's been a long time since I've encountered such a strange case!"

The officers of the Pre-Search Section 1 heard the introduction of the two section chiefs, and they all showed surprised expressions.

Previously, the police officers of the pre-search section 1, except for a few people who were directly involved in the investigation of the case, had only heard that the chairman of the Shengshi Group had been killed, and the details of the case were unknown.

"Ahem......!" Section Chief Gao John cleared his throat and said, "Now the National Police Agency has ordered the Xindu Police Headquarters to solve the unsolved case within a time limit. The homicide case is the responsibility of our pre-search 1 section, so it is our duty to pre-search 1 section to solve this case, if we can't solve this case within the time limit, I will resign and apologize! ”

When all the police officers heard this, they were restless again, and they all felt the importance and urgency of this matter.

"The head of the department has also mobilized the personnel of all relevant departments to participate in the investigation of this case, and the entire police headquarters and the criminal bureau have taken action." Su Fang added again: "Today's convening of everyone is to work together, and I hope that everyone can contribute ideas and suggestions according to the current situation, so as to formulate a follow-up action plan!" ”

"This is the case file of this case, and it is now distributed to everyone, please read it in detail, and draw up a proposal and plan for action according to your own ideas as soon as possible."

Suzukino pointed to the stack of materials on the table in front of him, and then said to Assistant Zhu Dan, "Distribute these to everyone!" ”

When Zhu Dan heard this, he skillfully picked up those documents and distributed them to all the police officers of the pre-search section 1 one by one.

"Do you have any questions?"

John asked, looking around at the crowd.

Seeing that no one answered, John Gao said, "Good! Let's read the case file! Tomorrow this time, a meeting on the course of action! ”

"If you have any questions, you can always find the section chief and me!" Deputy Section Chief Su Fang followed and said: "Everyone must pay attention to this case!" ”

"Yes!"

Everyone answered in unison......

Chen Chuyao and Li Andi returned to their seats and immediately began to study the case file of the Shengshi Group.

From September 24th to September 28th, Shengshi Group held the 2451 annual board of directors of Shengshi Group in Xilin Island, located in the West Sea.

Xilin Island is the private island of Shengjingfeng, on which buildings are built for vacations and meetings, and the board of directors of Shengshi Group meets annually on Xilin Island for security and confidentiality reasons.

The board of directors and related staff will be subject to strict security checks, and professional security personnel will be arranged on the island to take care of the relevant security work.

On the morning of September 25, Chairman Sheng Jingfeng's assistant called Sheng Jingfeng in the room several times, but received no reply. Then the assistant immediately found Sheng Jingfeng's two sons, as well as other members of the board of directors of Shengshi Group.

After a brief discussion, security personnel were ordered to use violence to open the locked door from the inside of the house.

Then everyone found Sheng Jingfeng lying on the ground in the living room, and he had been dead for a long time because he was hit on the head by a heavy object.

A brief inspection of the room revealed that not only were the doors locked from the inside, but all the windows were also locked from the inside, and no obvious signs of break-in were found.

Sheng Jingfeng's two sons and four other board members called the police after a brief discussion.

After receiving the alarm, the police station of Xilin Island and the police headquarters of the new capital rushed to the island one after another.

Because the police have not received any warning of the crime index from the beginning to the end, the police have not been able to obtain any information about the case from the super artificial intelligence.

Police officers immediately investigated the scene and questioned the people on the island one by one.

After forensic confirmation, Sheng Jingfeng's time of death was between 18:00 and 21:00 on September 24.

When questioning the relevant personnel, Sheng Jingfeng's assistant claimed that he had spoken to Chairman Sheng Jingfeng through the door at 20:10.

Sheng Jingfeng's death time has been reduced to 20:10 to 21:00.

According to the security personnel who have always been in front of the gate of the main hall where the chairman is located and the staff in the main hall, it is determined that no one has entered the gate of the main hall and the living room where Sheng Jingfeng is located from 20:10 to 21:00......

"This is called a locked room murder, right?"

Chen Chuyao finished reading the case file and said to Li Andi who was sitting next to him.

Li Andi nodded, and then said: "And it's a double secret room of the physical secret room plus the surveillance secret room!" ”

"The murderer not only created a closed room murder, but also successfully evaded the crime index warning!" Chen Chuyao then sighed: "It's really a tricky case......
