: The second year story 016, the back of the ghost

"Little...little trick?"
"That's right. These seemingly glowing blue lights, like ghost fires, have actually been manipulated. And the key secret lies in this glass bulb."
Principal Campa flicked the light bulb of the desk lamp and continued: "This glass bulb does not seem to have changed. In fact, it has been coated with a light blue attachment. This layer of attachment... It should be a painting. Pour the blue watercolor paint used for painting into water, and then apply it after diluting it."
After being explained by Principal Campa in this way, Walnut was a little bolder. She came over and took a look, but because she was too scared, she retracted back into the corner again: "No! If... if it were that simple, I should be able to see it! If you want to emit such a blue light, it will Paint a lot! I definitely can see it!"
"How do you tell? In the darkness."
"…………Uh……!"
Campa played with the light bulb in his hand and said, "The room is completely dark after you enter the door. At this time, it is impossible for you to see what is attached to the light bulb. Then, the first light you turn on after entering the door must be the chandelier on the ceiling. , This chandelier cannot be reached by you, unless you use a ladder, otherwise you will not be able to see what is painted on it. Under the blue light, even if you see this lamp or other lamps in the room emitting The light blue reflection would be thought to be the effect of light, but not the light bulb itself being manipulated."
"If you want to hide something, it's better to put it in front of you openly for you to see. Humph, really good at it."
The corners of Walnut's mouth twitched a little. This time, she finally got close to the light bulb and observed it carefully, and finally saw that there was indeed a layer of light blue dilute paint attached to the light bulb. But these are not enough, there are many other unsolved problems!
"Not only that! Mr. Campa, what about the blood flowing from the nozzle? It was good at first, but I saw it with my own eyes!"
Principal Campa put down the lamp and went straight into the bathroom. Walnut followed timidly, and after hesitating for a while, finally followed.
The water in the sprinkler is still on. At this moment, the water flowing out of it has been clean again. Principal Campa looked at the floor, and there were still red stains in some places. After he pondered for a moment, he stepped forward and closed the nozzle, pulled the nozzle part in front of his eyes, and repeatedly checked. Soon, he found what he was looking for.
"Look here."
Walnut leaned his head, and saw that the sprinkler of the nozzle had been taken apart by Principal Campa, and there was something squishy on the back. It seems to be paper.
"It’s easier to make red blood than blue light on the outside. Even timing is very easy. Just take a little out of the red paint, wrap it in this paper, and put it in here. Then, you turn on the water, and the water will slowly Wet the paper bag in the nozzle to disperse the red pigment. After a while, the red blood will be sprayed out of the nozzle."
"After the red paint is completely melted away, there is only this small piece of paper left, which has now been discovered."
The second mystery was solved immediately, but after Walnut saw that he had been fooled by the paint twice in a row, she gradually began to feel a little unconvinced. She raised her arm like angrily, pointed at the mirror where her face appeared, and said loudly: "Then... Then what about that face? Is that face also made of watercolor paint? I remember it clearly, I looked into the mirror before entering the bathroom, and there was no face on it! But when I left, there was that face on it!"
Principal Campa walked to the mirror. At this moment, the face on the mirror has disappeared. After thinking for a while, he suddenly turned on the steam release switch and waited quietly.
Walnut shrank behind Headmaster Campa and looked at the mirror with some fear. The mist in the bathroom became dense again, and the air became humid and warm. And the mirror began to be covered with water mist. In this water mist, gradually... gradually...
"Ah! This is the face! Headmaster! Look! This is the face!"
After being misted on the mirror that didn't have anything just now, a slightly distorted face appeared again in front of Principal Campa and Walnut.
Principal Campa stepped forward and stretched out his finger to touch the mirror slightly. Then he smiled again.
"Princess, it's still a little trick, not a ghost."
"How... how do you say?" Walnut turned pale again when he saw Campa dare to reach out and touch the face of "Ghost".
"Here, the person who set up this mechanism took advantage of a characteristic of water. That person painted another liquid on this glass in advance to paint a human face. After the liquid dries, you can see if you are I can't see anything. But once you turn on the water, the mist is diffused and the water vapor adheres to this mirror, the water will not be able to adhere to the mirror surface with dried liquid due to its own characteristics. So as to outline his ghost face drawn long ago."
"So then, what is that dried liquid? Isn't it a very special liquid that is hard to get?!" Walnut asked loudly, anxious.
"Special? Rare? No, no, no. This kind of liquid is actually very common. As long as you use the liquid's ‘incompatible water and oil’ property, and paint a grimace in advance, it’s fine."
Walnut was completely stupid now. She looked at the face in the mirror blankly, and suddenly stretched out her hand to wipe it, and the grimace was immediately wiped out.
"Hehe, next, let me tell you the inner meaning of the grimace on the last door by the way."
Principal Campa walked out of the bathroom, brought walnuts to the corner facing the door, and saw the face behind the door. At this moment, this face is still very clear.
"Then that... Mr. Campa, how did this face appear? I bet that I locked the door since I entered the room. There was absolutely no such face at that time!"
Principal Campa walked into the door, touched his grimace, smiled slightly, and said, "Of course, because this face was not painted by someone after you entered the room, but was painted here from the beginning. "
"Ah? This is impossible! When I closed the door, I was facing the door. How could I not see it? And after...I was pretty sure that there were no faces on it!"
"Are you really sure? Did you really confirm the situation on the door when you entered the room?"
"……I!………………"
Principal Campa stroked the grimace and slowly said: "When you first entered the room, the room was completely dark. And this face was painted with black paint. Of course you can’t notice. The blue light enters the room. Because the door is at right angles to the room, since you enter the living room, the door has become a blind spot for your sight. Unless you want to leave again, you will never find the face on the door. , You became panicked because of the face that appeared automatically in the bathroom. When you fled to the door, you saw this suddenly appearing face again, and you were immediately frightened."
"But in fact, this face has a more difficult task than the other three mechanisms that scare you. For those who set these traps, if you really escape from the room, it will be difficult for him. To do. So draw this face, which means that you are to stay away from the door and be trapped in this room by your own fear. Then he reappears and easily achieves some goals from you."
Four haunted incidents were uncovered one by one, and of course Walnut immediately understood who was causing it. Her small face, pale because of panic, was now pale with anger, and the anger that seemed to be frightened for a long time was enough for her to kill the person who set the trap thousands of times.
Campa didn't ask in detail, he just looked at Walnut's eyes. After about a minute of thinking, he decided to fully express his inference: "But princess, it is not easy to complete this series of'intimidation'. Human fear cannot be ignited without any ignition. The cable is automatically triggered. I think you must have received some'cues' before. Although you did not pay attention, this trap may have been activated since then."
Walnut was startled, and immediately remembered the scene where the idiot held the mirror and argued in front of Dai Lao during the day, telling stories and pleading, and finally broke the mirror on the ground. If you think about it this way, what he was performing at that time was basically a play! And the audience in his scene is not the three of Dai Lao, they are themselves hiding in the dark!
Yes, think about it carefully, if you didn't hear the idiot, and saw the idiot's actions, how would you understand these haunted institutions?
The lighting problem may be thought to be the aging of the light inside.
Blood water may think it is rust.
The face on the mirror might think it was occasional mist.
It's impossible to misidentify the face on the door, but you should think it was someone's prank, so you can tell the teacher to look for the prisoner.
Principal Campa continued to look at Walnut, seeing her frowning and thinking, she must have understood something. But before that, he had some things that he didn't understand, so he asked: "But princess, it is actually a very time-consuming task to complete these mechanisms. But why did the person who set up the mechanisms come in so boldly. What? If you come back halfway, as long as any of the four organs is not set up, everything may be exposed. I can hardly imagine the other party's ability to guarantee that you will never come back in a short time."
Walnut also found it strange to be reminded by Campa. But her strangeness only lasted less than thirty seconds, and the doubt was immediately solved!
