Chapter 423 The truth about the haunting

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

"Why did I hear someone screaming?"

"Can you really stop making trouble? I have to hand in my paper tomorrow."

Along with a shrill scream outside the apartment, people in the apartment who had just returned to their rooms walked out one after another.

After all, the screams outside were too loud, and they were afraid that there might be some accident at the door.

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

"It seems that it came from the closed building opposite the apartment." Xiaolan said uncertainly as she lay outside the window.

"Go out and take a look!" Conan's expression was solemn, thinking that Tang Ze seemed to realize something when he went out, and he quickly got up and ran outside.

Led by Conan, Mouri and Kogoro also ran downstairs.

When a group of people appeared at the door of the apartment, they saw Tang Ze walking over with a man with a bruised nose and face, and his right arm was obviously hanging there, obviously dislocated.

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

When they got closer, everyone saw the scar on the other person's face clearly and unconsciously turned their heads to look at the wanted poster posted on the telephone pole.

"He, he is."

"The wanted criminal who killed and burned corpses!!"

Although the face of the man being held by Tangze was bruised and bruised, everyone recognized him immediately after getting closer to him due to his conspicuous scars and his evil-looking appearance.

"How come? Tang Ze Criminal, why is this fugitive here?" Xiao Lan said in confusion.

"Because the red firelight floating in the building opposite is the firelight when this guy is smoking, and the cyan figure is the light emitted by the portable TV that someone took over."

Tangze glanced at the few 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 is a prisoner among us!?"

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

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

This is such a scary thing, just thinking about it makes my scalp numb.

"So, do you want to save me some trouble by opening your mouth, or do you want me to find your accomplices and accompany you?"

Tang Ze looked at the man in front of him and smiled and said, "Think carefully. If you can identify your accomplices, it will be regarded as a crime and meritorious service. When the time comes, I will report the truth truthfully so that you can get a lighter sentence."

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

"Oh? That's okay. I'll take the opportunity to solve the mystery of the haunted house and your accomplices at once." "Accomplice!? Haunted house!?" Mouri Kogoro suddenly turned his head to look at the apartment after hearing this. The four residents asked, "Are you saying that this haunted house was created by an unknown murderer!?"

"That's right." Tangze smiled and said: "We have already explained the principle of a female ghost suddenly appearing on the TV. It can be easily solved by using the remote control. Other phenomena are similar to this."

"What happened to the bright red blood water?" Mudan Luyan asked puzzledly: "I saw it with my own eyes at the time. There was no red water in the water tank."

"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 there is a faint smell of alcohol in the toilet tank."

Tangze smiled and said, "This is an experiment that elementary school students would do."

"Ah, I know!" Conan said in a coquettish voice and started to steal the show, "If you mix the alcohol containing dissolved phenolphthalein with alkaline ammonia, it will turn red!"

"In other words, if you add alcohol containing phenolphthalein to the water tank, and then add ammonia to the toilet water, as soon as you flush the water, a chemical reaction will occur when the two liquids mix and turn red."

After hearing the answer, Mouri Kogoro was a little confused. After all, he was scared to death by the fact that this elementary school student knew all the tricks, which made him even more angry at the person who was behind the scenes.

"Wait a minute, I understand what you're saying, but it may not go smoothly, right?"

Mudan Luyan questioned a little: "The liquid that came out after the two were mixed in the experiment you mentioned is slightly pink. This is very different from the dark red blood, right? Not to mention that it's not just a person's mistake."

"If it were simply placed during the day, it would be impossible to admit the mistake, but obviously there is no such good lighting conditions in this dim bathroom."

Karasawa explained: “In addition, there have been rumors that this house is haunted, which gives everyone a subconscious feeling of preconceptions.

Therefore, when encountering something weird, the brain will immediately think of the matter in a scary direction, which is the so-called scaring itself. "

"But even so, urine shouldn't have any chemical reaction with the two things you mentioned, right?"

Mudan Luyan, a graduate student, was a little unconvinced and said: "The ammonia in urine is acidic or neutral, not alkaline."

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

Tangze nodded and said, "This is a very simple psychological problem. Sometimes, we trust what we smell more than what we see visually.

Therefore, if ammonia is poured into the toilet in advance, the strong odor will make people suspect that the toilet is too dirty. In this case, flushing the water before using it again will play into the hands of the prisoner. "

"What about the ghost we saw by the window before?"

Yotsuya Iwa didn't want to believe that the "ghosts" he expected were just simple scientific principles. He pointed to the window before and said: "That ghost was seen by all of us with our own eyes!"

"This is even simpler." Tangze pointed to the window and said: "The so-called ghost is just an aggregation of male moths.

They are attracted to female moth pheromones used to repel insects outside the window. As long as we put eyes and mouth cut out of black paper on the outside of the window, then when we look inside the house, we will naturally think it is a ghost from a distance. . "

Pheromones are colorless and odorless hormones used to attract the opposite sex.

As for this kind of pheromones used by civilians to kill insects, some other scents are added to remind them that there is spraying here, so Tangze easily analyzed the trick played by the other party.
