Miss Lychee continues to talk about her theory of murder in a closed room.

"The third situation is the escape room trick, which is simply to escape from the secret room in a way that ordinary people would never think of, such as using bone shrinking to leave the secret room through the exhaust hole, or walking a tightrope to get out of the secret room like an acrobat." Miss Litchi continued: "Judging from the situation of this case, the only thing that no one in the entire main hall is the west window of the main hall located on the edge of the cliff, if the murderer is a person who is good at high platform diving, he can jump into the sea from the west window and escape from the scene of the crime. ”

In the face of such an unexpected analysis, Chen Chuyao and Li Andi glanced at each other in unison, and their expressions were a little subtle.

"However, given that all the doors and windows at the murder scene are locked, it seems that the murderer jumped into the sea from the west window to escape."

Miss Lychee once again denied her own speculation.

"In other words, since you have chosen the unexpected method of jumping into the sea, there is no need to lock the doors and windows anymore, right?"

Andy Lee echoed.

"Yes!" Miss Lychee bowed slightly, and then said: "Since the first three types of secret rooms have been denied, there is only one last possibility for this secret room murder!" In the fourth case, the murderer was in the room at the time of the crime, and then through some means, the murder scene was faked into a secret room. ”

"How is the Chamber of Secrets made?" Andy Li asked cooperatively.

"Because Sheng Jingfeng's murder case is a double secret room, what really bothers the police is actually the surveillance secret room, that is, everyone on the island does not have the conditions to commit crimes." Miss Litchi explained: "On the other hand, physical secret rooms are not difficult to do, but more of a confusing effect. ”

While speaking, Miss Lychee came to the door, pointed to the door lock and said: "The structure of this door lock is similar to that of the living room of the Shengjing Summit, you can see here, you can use a fishing line to tie it to the knob of the door lock, and then pull the fishing line from the outside of the door, creating the illusion that the room is locked." The knob structure of the window is simpler, and the same technique can be used. ”

Li Andy nodded and said, "I have confirmed that the window of the main hall is not very tight, and the sealed rubber strip can completely pass through the fishing line." ”

"It's just the simplest of things." Ms. Litchi adds, "You can also use nano-shapeshifting robots to lock the room and then spread out and leave through the cracks in the doors or windows. ”

Nanobots are extremely tiny robots, like atoms that make up matter, and a large number of nanobots can be freely arranged and combined to form anything of the same volume.

"Using nanobots is a better way." Andy Lee echoed: "If you are carrying a small number of nanobots, you can disguise them as daily necessities and pass through the security check. ”

"In short, it doesn't matter how you use the physical room, I can come up with a lot of different ways if I need to." Miss Lychee's tone became more solemn, and then she talked about the key part, "How the murderer entered the surveillance room and how he left the surveillance room, that's the point!" ”

"Was the murderer one of the four directors?" Andy Lee asked tentatively.

Chen Chuyao continued to play the role of a quiet listener, and at the same time pondered Miss Lychee's seemingly nonsensical reasoning.

"The murderer is Guo Ziteng!" Miss Lychee spoke loudly.

"Guo Ziteng?" Andy Lee repeated the name while showing a confused expression, "How did he escape the surveillance of the security guards and enter the main hall?" ”

"It's easy! Do you think about it, when a few directors went to the main hall, what was the difference between Guo Ziteng and the other directors? Miss Lychee asked.

"Guo Ziteng went by shuttle bus, while the other three directors went on foot." Andy Lee replied.

"Then why does Guo Ziteng have to take the shuttle bus?"

"Is it to avoid the surveillance of the security guards?"

"Exactly!" "The parking lot in the vestibule is on the north side of the annex, while the security guards are on the south side of the annex. In addition to the revolving gate on the front, there are side doors facing south and north on either side of the revolving door. If you take the shuttle bus and get off the parking space on the north side of the annex and enter the annex through the side entrance, the security staff on the south side will not be visible. ”

"What Miss Litchi means is that after Guo Ziteng returned by car, he did not return to the annex, but the security personnel saw Guo Ziteng returning to the parking area of the annex by car, so they thought that Guo Ziteng had entered the annex through the side door on the north side."

Li Andy followed Miss Lychee's prompt and analyzed.

"Because all the staff were attending the bonfire party on the north shore of artificial lake at that time, no one in the annex could prove that Guo Ziteng did not return to the annex at around 18:55." Miss Litchi continued, "Then Guo Ziteng avoided the sight of the security personnel, walked north, and then used the fountain that erupts every 30 minutes to enter the main hall through the east window of the main building. ”

"In other words, Guo Ziteng entered the main hall at around 19:00." Li Andi was puzzled: "But Sheng Jingfeng was killed between 20:10 and 21:00!" ”

"It's very simple, after Guo Ziteng entered the main hall, he found a place to hide, and it wasn't until his assistant Feng Shalun asked Sheng Jingfeng about it, and then returned to the meeting room to kill Sheng Jingfeng, and then used the fountain that erupted at 20:30 to leave the main hall."

"How did Guo Ziteng evade the surveillance of super artificial intelligence?" Andy Lee then asked.

"It must have been a data-masking device."

Miss Lychee gave the most simple and straightforward answer.

With that, Miss Lychee showed a confident expression and stood there with the attitude of a victor, with a graceful demeanor.

"I have a different opinion about the suspect!" Andy Lee said with a smile.

"In mystery novels, if there are not a few pseudo-answers, it really seems boring!" Miss Lychee smiled disapprovingly, "But I'm not interested in the pseudo-solution, so you two can continue to discuss!" ”

After that, Miss Lychee went to the next room, leaving Li Andi and Chen Chuyao who looked at each other.

"Miss Lychee has always been very confident in her reasoning!" Andy Lee said with a little self-deprecation: "So I think my inference must be a false answer." ”

"Andy, tell me about it!"

Chen Chuyao said softly, ready to continue to play a competent audience.

Li Andi had long been accustomed to Miss Lychee's style of acting, so he didn't care, but smiled and continued: "I think the murderer should be Wang Zhitao. ”

Chen Chuyao nodded, thinking about Wang Zhitao in his heart.

After Wang Zhitao returned from the main hall, he left the annex at around 19:00. According to security personnel, he went to the artificial lake to the north. But after investigation, people in the artificial lake said that they had not seen Wang Zhitao during the bonfire party. Andy Li analyzed: "In other words, he must have gone somewhere else." It is completely possible to detour from the north side, and then use the cover of the fountain to enter the main hall through the east window of the main building. And Wang Zhitao's secretary also left the bonfire party around 19:00, and the two of them are likely to cooperate in committing the crime. ”

"From the perspective of time and space, Wang Zhitao does have the conditions." Chen Chuyao followed up and analyzed: "And Wang Zhitao has a full motive for the crime, which is to help Ben Sen sit in the position of chairman." In contrast, Guo Ziteng's motive for committing the crime is not clear at present, after all, from all aspects of the information, Guo Ziteng is Sheng Jingfeng's most loyal supporter. ”

"That's true, when Miss Litchi suggested that Guo Ziteng was the murderer, I also felt that his motive for committing the crime was not accurate."

Although they had some doubts, the two of them tacitly did not question in front of Miss Lychee.

"According to my investigation, when Wang Zhitao returned that night, his shoes were stained with black mud, and there was no such black mud in the campfire venue or on the main road." Andy Lee continued: "However, there is this kind of black soil that is conducive to planting on the grass outside the east window of the main hall and the fountain, and the fountain erupts regularly, so that the grass is always wet, so after walking on it, you will leave black soil on your shoes. It can also prove that Wang Zhitao once walked through the grass, and then entered the main hall through the east window of the main hall. ”

"However, according to the case file, there is no sign of entry or destruction near all the windows of the main building." Chen Chuyao asked.

"I guess when Wang Zhitao came to the east window, he found that his shoes were stained with a lot of mud, so he had no choice but to take off his shoes before entering the main hall, as for the shoes can be hidden in the grass without being discovered." Andy Lee explained.

Chen Chuyao nodded and did not question again.

The rest of the matter is roughly the same as Miss Lychee's reasoning! After Wang Zhitao entered the main hall, he first hid, and then waited for the assistant to leave, entered the living room and killed Sheng Jingfeng, and then used the eruption of the fountain to leave the main hall. As for the methods of locking doors and windows and avoiding super artificial intelligence, it should be similar to Miss Lychee's reasoning. ”

"Andy's reasoning is similar to Miss Lychee's reasoning in terms of technique, but Mr. Andy's inference is more reasonable in terms of the motive for the crime." Chen Chuyao followed.

When Li Andy heard this, he thought that Chen Chuyao felt that his reasoning was better, and couldn't help but smile with satisfaction, "What does Chu Yao think?" ”

"The crime index warning of super artificial intelligence not only relies on monitoring, but also extrapolates a large amount of past data to predict future behavior." Chen Chuyao said his thoughts, "So I think it's just a simple use of data shielding equipment to block monitoring, and I'm afraid it can't completely escape the monitoring of super artificial intelligence." ”

"What Chu Yao means is that there is still a need for in-depth discussion of specific techniques at this point?"

"I always think that the murderer's method of evading super artificial intelligence is one of the important links in the whole case, but now our inferences consider this matter too simplistic!"

Chen Chuyao nodded in response......
