Detective Training Manual

"Tsk, it's impossible." Zhou Yan frowned, "Did you make a mistake? Are you really staring at the garage door? Or... will the little man? He would just hide outside the garage. When you went out and ran towards the tree for a few seconds, he swooped into the garage."

　　 "Impossible!" At this time, the little boy in front of him behaved abnormally affirmative: "I am not a newbie in this game, I am very careful. After I got out of the garage, I didn't run directly to the tree.

　　 Instead, he turned his head and closed the garage door first, and then ran over while paying attention to the surroundings. If someone approached during this period, I couldn't find it. "

　　 "Huh? That was not the case when you demonstrated just now." Zhou Yan questioned.

　　 "Nonsense! If I close the garage door when I demonstrate, how do you get out?!"

　　 "Hey...okay." Zhou Yan curled his lips.

　　 Actually now, the facts of the case are already very clear.

　　 Probably it was... the boy named Xiaofu, under Nobita's constant gaze, escaped his vision and entered a space with only one exit.

　　 "Hiss...how does it sound like an alternative secret room." Zhou Yan muttered.

　　 And Lin Xi on the side also nodded: "Yes, it's the secret room!"

　　 "Hey, can a child play a game, can it be involved in a bridge such as a secret room? Are we thinking too much?"

　　 "Don't be so unmotivated, we are detectives. You can't think of things too simple just because the client is a child." Lin Xi whispered, "Actually, if it's a secret room, it doesn't seem to be that difficult to unlock.

　　 Because, over the years, countless detectives have summed up all the various methods of the ‘secret room’. "

　　 "Huh? Is there a summary?" Zhou Yan was taken aback.

　　 "Of course...from ancient times to the present, in fact, all secret rooms are nothing more than the following types.

　　First: false secret room.

　　 is the scene of the crime. It is not a secret room at all. It just looks like a secret room because of some mechanism.

　　 More representative examples are ‘lock outside the door’, ‘use a mechanism to let the window fall’ and so on.

　　The solution to this kind of secret room is to find that mechanism.

　　 The second type: real secret room, remote crime

　　In this kind of case, the secret room is true. It is true that no one can enter and no one can come out.

　　 But the murderer can be outside the secret room and cause harm to the people in the secret room.

　　 It's like throwing a flying knife into a secret room from a window that humans can't pass through, and then using the line behind the flying knife to pull the flying knife back.

　　 The key to unlocking this kind of secret room is to find the killing technique, not the secret room itself.

　　 The third type: Temporary secret room

　　 This kind of secret room is not very common. The key point is that this secret room is not a secret room at all, but it becomes a secret room the moment it is discovered.

　　 I gave an example: a person came to the door of a room and kept hitting the door, making everyone think that the door was locked.

　　 But in fact, the door of this room is not locked at all, it is just that he temporarily pretended to be in front of other witnesses.

　　To unlock this kind of secret room, you just need to break the murderer's blindfold.

　　 In addition, there are some less representative secret rooms.

　　 For example, the murderer has been hiding in the secret room, ignoring that other people have not found it.

　　 Or the deceased ran into the secret room by himself, locked the door, and died in the secret room.

　　 Or, the murderer used visual or psychological blind spots.

　　Even...there are the murderers who belonged to the circus, training monkeys to get into the secret room, helping to pick up the murder weapon.

　　 In short, don't see the secret room, just have a headache first. "

　　 Zhou Yan nodded, but he was a little surprised in his heart now.

　　Because in his mind, the detective is still like the world before he was reborn, and he can only solve the case by relying on his own brain or some sudden inspiration.

Unexpectedly, in this world, among the detectives, there are already textbook-like summary documents like "Encyclopedia of Secret Chambers"~www.readwn.com~Could it be that this world will give detectives? Are universities and professional courses set up specifically?

　　 Uhhhhhhhhhhhhhh, it seems to be the same if you think about it this way.

　　 "Well, it seems to be quite powerful, then... which one do you think our case is more inclined to?" Zhou Yan asked.

　　 "It's not certain yet, but we can exclude some options." Lin Xi thought and said:

　　"For example, this is definitely not a false secret room, because this garage is a real closed space. It is impossible for the boyfriend to start digging a tunnel a few months in advance, just for this treasure stealing game.

　　Also, it shouldn't be a remote crime, because Daxiong saw with his own eyes that Xiaofu classmate came out of the secret room.

　　So, among the remaining possibilities, the most suspected one is...

　　 1. How can the little husband sneak into the garage without hiding Nobita’s sight?

　　 2. The little man has a way to hide in the garage, but he doesn't let Nobita find out.

　　3, Xiaofu used some kind of blindfolding method to make Nobita think that he walked out of the garage, and he also held the "treasure" in his hand. "

　　 Zhou Yan listened and shrugged.

　　 "Yes, these three methods correspond to [through the wall] [invisibility] and [illusion]. Otherwise, we will show down directly and tell Nobita that your classmate is actually an alien."

　　 He said so in his mouth, but he didn't think so in his heart, because Zhou Yan took out the detective's notes while saying it...

　　 "Cut, even if it's really an alien, our ‘Zhou’s Detective Team’ can find it out for you..."
