Detectives of Detective World

"Nani! Nani! What happened?! What happened!"

"Why did I hear someone screaming..."

"Really... can you stop making trouble, I have to hand in my thesis tomorrow..."

Accompanied by a shrill scream from outside the apartment, the people in the apartment who had just returned to their room came out one after another.

After all, the screams outside were really loud, and they were also afraid that there was an accident at the door or something.

Naturally, Mr. Otonashi, Kogoro Mouri and others on the second floor also heard the sound, but when they looked out from the second floor, they didn't see any figures.

"It seems... it came from the suspended building opposite the apartment..." Xiao Lan was a little uncertain while lying outside the window.

"Go out and have a look!" Conan's expression became solemn. Thinking of Tang Ze's appearance, he seemed to realize something, so he quickly got up and ran out.

Under the leadership of Conan, Mouri Kogoro and the two also ran downstairs.

When a group of people appeared at the door of the apartment, they saw that Tang Ze walked over with a man with a blue nose and a swollen face, and his right arm was obviously drooping there, obviously dislocated.

Obviously, the scream was caused by Tang Ze unloading the arm of the man in front of him.

When it was approaching, everyone saw the scar on the other's face and turned their heads unconsciously to look at the wanted notice posted on the telephone pole.

"This... he, he is..."

"The wanted criminal who murdered... burnt the body!!"

Although the face of the man being held by Tang Ze was blue and purple, the conspicuous scar and the appearance of a wicked man were immediately recognized by everyone.

"How... Tang Ze criminal, how can this fugitive be here." Xiao Lan was puzzled.

"Because the red light wafting from the building opposite is the light when this guy was smoking. As for the blue figure, it was the light from the portable TV that someone took over."

Tang Ze glanced at several people with a playful look on their faces: "Based on all aspects of the situation, another guy who was not seen by witnesses is also here now."

"what...!!"

"You said there were criminals among us!?"

"How is this possible? Who is it!?"

Hearing Tang Ze's words, several people's expressions changed drastically. No one would have imagined that they would live in the same apartment with a murderer for four years.

This kind of thought is extremely frightening, just thinking about it, can't help but tingling in the scalp.

"Then, did you ask me to save me some trouble, or let me find your accomplice to accompany you?"

Tang Ze looked at the man in front of him and said with a smile: "You can think about it. If you can pass the accomplice, then it will be considered a crime and meritorious service. When the time comes, I will report it truthfully, so that you can reduce your sentence."

"Hmph..." The other party snorted disdainfully after hearing Tang Ze's words, and turned his head to the side, obviously not planning to cooperate.

"Oh? That's fine. I'll take this opportunity to solve the mystery of the haunted house and your accomplices at once."

"Associate!? Haunted house!?" Kogoro Mori suddenly turned his head to look at the four residents of the apartment, "You mean this haunted house was created by a murderer who doesn't know its face!?"

"That's right." Tang Ze smiled and said, "We have already explained the principle of the sudden appearance of female ghosts on TV. It can be easily done with the remote control, and other phenomena are similar to this."

"What's the matter with the bright red blood?" Mudan Luyan asked, "I saw it with my own eyes, but the water in the tank didn't have any red clear water."

"It's a very simple principle. I don't know if you can smell it. There is a strong smell of ammonia in the bathroom, and a faint smell of alcohol in the water tank of the toilet."

Tang Ze smiled and said, "This is an experiment that elementary school students will do."

"Ah, I know!" Conan began to grab the scene in a milky voice, "Alkaline ammonia is mixed with alcohol containing dissolved phenolphthalein,

It's like turning red! "

"That is to say, add alcohol containing phenolphthalein to the water tank, and then add ammonia water to the toilet water. As long as the water is flushed, the two liquids will chemically react and turn red..."

After listening to the answer, Kogoro Mauri couldn't hang up. After all, he was frightened to death by the fact that this elementary school student knew how to do tricks, which made him even more annoyed at the ghosts behind his back.

"Wait, I understand what you're talking about, but it may not be smooth, right?"

Mudan Luyan questioned: "The liquid you mentioned after mixing the two in this experiment is slightly pink, which is very different from the dark red blood color? Not to mention, it is not a mistake. .."

"If it is simply placed in the daytime, it is naturally impossible to admit it wrong, but obviously this dim bathroom does not have such good lighting conditions."

Tang Ze explained: "In addition, the fact that this house is haunted has been circulating, so that everyone has a preconceived feeling in their subconscious.

Therefore, when encountering a strange thing, the brain will immediately think about it in a terrifying direction, which is the so-called scaring yourself. "

"But even so, urine shouldn't have a chemical reaction with the two you said, right?"

As a graduate student, Mudan Luyan was a little unconvinced: "Amonia in urine is acidic or neutral, not alkaline..."

"That's why I chose ammonia with a strong smell as the reaction liquid."

Tang Ze nodded his nose and said, "This is a very simple psychological problem, and sometimes I believe in what I smell rather than what I see visually.

Therefore, if ammonia water is poured into the toilet in advance, the strong odor will make people suspect that the toilet is too dirty. "

"And what about the ghosts we saw by the window earlier?"

Yotsuya Yan was still unwilling to believe that the "ghosts" he expected were just some simple scientific principles. He pointed to the previous window and said, "We all saw that ghost with our own eyes!"

"It's even simpler about this." Tang Ze pointed to the window and said, "The so-called ghost image is just an aggregate of male moths.

They are attracted by the female moth pheromones used for repelling insects outside the window. As long as the eyes and mouths cut out of black paper are pasted outside the window, we will naturally think it is a ghost when we see it from a distance. . "

The so-called pheromones are pheromones, which are colorless and colorless hormones used to attract the opposite sex.

As for this kind of pheromone for civilian use, some other flavors will be added to remind that there is a spray here, so Tang Ze easily analyzed the trick played by the other party.
