Detective Conan: The System Takes Me to Zero's World

Mao Lilan's eyes were fixed on Conan, and her mind suddenly moved: [Email? Yes, the policeman before, I did see him check his mailbox.]

The blue light of the system screen flickered, pulling her thoughts back to that sunny afternoon when the sunlight shone through the branches and leaves, casting mottled shadows on the mailbox.

Kudo Shinichi saw with his own eyes Matsuda Jinpei holding a lock picking tool and tentatively inserting it into the keyhole of the mailbox. He looked like a thief ready to steal.

The strong sense of justice in his heart suddenly surged to his head, and his face was full of dissatisfaction: "How can you just pick the lock of someone else's mailbox?"

Mao Lilan nodded quickly: "What's the difference between this and a thief!"

Matsuda Jinpei paused for a moment, still wearing that cynical smile on his face, and said casually, "What do you call this? It's an extra-legal measure that goes beyond the scope of the law. It's reasonable for the police to investigate the letters received by the bad guys."

He even raised his eyebrows towards Idahang, as if seeking approval.

Yi Dahang stood aside, the corners of his mouth slightly raised, and chuckled: "Hahaha, there is actually no such rule, don't learn it."

Matsuda Jinpei pretended not to hear anything and continued fiddling with his hands. With a crisp "click", the lock opened. He couldn't wait to search for it and soon found the electricity bill.

He frowned slightly, but the corners of his mouth raised a smug arc: "Sure enough, the electricity bill is over 3 yen, just as I expected. There must be something wrong with this guy."

Yi Dahang went forward to check, his expression serious: "The situation is indeed suspicious. We now need to conduct a home investigation and get the details from the residents."

Standing at the gate of the fence, Furuya Rei made the call, his tone respectful yet cautious, "Yes, Instructor Onizuka. We received intelligence that a suspicious person was living here, so we came to check it out, and it turned out to be true."

On the other end of the line, Onizuka Hachizo's roar came instantly, shocking Furutani Rei to quickly put the phone away: "What I'm asking is, why did you guys skip classes at the police academy to investigate? Don't think that I don't know what you guys are planning just because Kudo Yuki is covering for you!"

A trace of helplessness flashed across Fūya Rei's face, as if saying "here we go again". Every time he got angry, he would be scolded by the instructor.

He patiently explained, "Instructor, this won't work. Those residents have probably seen us in uniform. If we leave now, they will probably run away immediately. This is a rare opportunity, and we must not miss it."

Onitsuka Yazo sighed and slowed down his tone a little: "What about Kudo Yuki? Did she follow you guys in making trouble? Isn't she always the most well-behaved?"

Fūya Rei's lips curled slightly, and the image of Kudo Yuki appeared in his mind. He replied: "Xiaoxue revealed the information to us in advance. She is busy cooperating with Manager Kuroda to deal with some difficult cases recently, and she can't get away.

But she repeatedly told us to be careful and not to make any mistakes, and she explained everything clearly. "

Onitsuka Yazo snorted coldly: "She is smart and knows how to clean up after you. You guys better be careful and don't mess things up, otherwise I won't forgive you!"

After hanging up the phone, Furuya Rei walked towards the crowd. At this time, his companions who were scattered in various places were nervously preparing for the next action.

In the department store, Zhu Fujingguang was walking between the shelves with a shopping basket, muttering to himself in a low voice: "Sugar, baking soda, camphor and ethanol... the pharmacy should have them."

He scanned the merchandise, searching carefully for his target.

At the same time, the roar of engines suddenly sounded in front of the repair shop of the Metropolitan Police Academy.

Hagiwara Kenji opened the car door and got into the driver's seat. He raised his eyebrows and smiled at the staff, "Instructor Onizuka said that the engine of this car is not very good, so he asked me to try it. I forgot about it when I was playing catch and got scolded. I'm here to make up for it!"

"Really? Why do you suddenly want to test drive the car?"

Hagiwara Kenji opened the car door swiftly, got in, and started the car: "Don't worry, I have good skills, there will be no problem."

The staff shouted at the top of their lungs: "Mr. Onitsuka loves this car very much, please don't damage it."

"Okay!" Kenji Hagiwara stepped on the accelerator hard, the tires rubbed against the ground with a harsh sound, and the car sped away in a cloud of dust.

Near the park, Date Kou crossed his arms and said, "Oh, Zero, what did Instructor Onizuka say?"

"I finally managed to deal with it." Furuya Rei watched Matsuda Jinpei's actions and then asked, "Did the residents of this house respond?"

Matsuda Jinpei kept ringing the doorbell, frowning and complaining: "I pressed the doorbell for a long time, but there was no movement. I don't know if there is anyone inside."

With a click, the door opened and three men walked out. The two men standing in front looked a little nervous.

"Yes, what's the matter?"

“Why did the police come to my house?”

Date Kou looked at Kudo Shinichi and Mao Li Ran and explained, "These two children said they saw something strange in the courtyard, so we came to investigate."

The thin man pretended to have just remembered: "Oh, there were a few little ghosts shouting last night, 'A monster has appeared!' They must have seen it wrongly."

Mao Lilan immediately retorted: "We are not talking nonsense! There are many burning fish swimming around in the pond, and a black snake came out of the smoke."

Kudo Shinichi pointed at the fat man and said, "It was you who took pictures of us with ghosts behind us and said we were cursed and asked us not to come again."

The fat man played dumb: "Oh? What are you talking about? I have never done such a thing."

The thin man leaned forward slightly, with a bit of disdain: "If you have the time to take this kind of made-up story seriously, you might as well catch someone worse and stop wasting your time here."

The fat man also echoed: "That's right, don't waste time here."

Zhu Fu Jingguang walked in carrying a bunch of things, "Then let's do an experiment. I've bought all the materials. Let's see if this is fabricated or not."

Kenji Hagiwara drove over, got out of the car and stood by outside, ready to help at any time.

Rei Furuya helped with the drilling demonstration.

Zhu Fujingguang raised a mysterious smile and picked up a piece of camphor with his hands: "Watch it!"

He arranged the camphor sheets neatly on the aluminum foil board, and as soon as the flame touched it, several small blue flames suddenly popped up on the silver-white board.

"Whoosh——" As he blew, the burning aluminum foil slid lightly into the pool, and several balls of flames immediately floated on the water.

Mao Lilan was so shocked that she covered her mouth: "The fire is swimming in the water!"

"This is the secret of surface tension." Zhu Fujingguang tapped the water surface with tweezers. The moment ripples appeared, the flame suddenly accelerated. "The water is like a layer of elastic plastic wrap. The dissolved camphor punctures this 'plastic wrap', and the flame is naturally like being pushed by someone."

A few flames flew into the pool.

Mao Lilan and Kudo Shinichi were stunned.

"There's fire swimming!"

"That's it! That's what we saw!"

Mao Lilan looked up and asked, "Why is this happening?"

Zhu Fu Jingguang patiently answered: "When an object floats on the water, it will be affected by the surface tension that is invisible to the naked eye. The forces in all directions are balanced, so it will remain still on the water surface.

Camphor dissolved in water will weaken the surface tension. When the fire is lit, the camphor will dissolve faster, which will also weaken the tension faster, so the object will move faster. This is all scientific principle.

Kudo Shinichi suddenly realized: "Oh."

Mao Lilan was a little surprised and praised: "You look like a science teacher."

Zhu Fu Jingguang was stunned and scratched his head: "Really?"

Mao Lilan closed her eyes and smelled: "Huh? It seems to have a burnt smell."

Kudo Shinichi noticed something like fog on the ground around him and looked down: "Smoke? Where is this smoke coming from?"

The smoke behind them was getting thicker and thicker. Mao Lilan and Kudo Shinichi looked back and exclaimed in fear: "Exit, a big black snake appeared!"

"Ding ding! This is the truth about the Black Snake!" Kenji Hagiwara stood up with a smile on his face, holding the box.

"Mix sugar, baking soda and ethanol in appropriate proportions, pile them in the middle of an iron basin covered with gravel and light a fire. The sugar melts and the baking soda decomposes to produce carbon dioxide, which causes the sugar to expand. When the water is burned dry and carbonized, a large black snake is formed."

Matsuda Jinpei also added: "This is a wonderful display of chemical reactions."

Mao Lilan listened attentively, with curiosity shining in her eyes, and praised sincerely: "Although I don't understand a lot of things, I really feel it's amazing!"

Matsuda Jinpei slowly turned the flashlight, and the cold light swept across Kudo Shinichi's face, with a sly light flashing in his eyes: "Have you learned something new, boy?"

Kudo Shinichi met the provocative look, "Yes, but you don't look like a teacher at all."

Two people with very different personalities are competing with each other at this moment.

The burly man standing behind put on a false smile and spread his hands: "What can the experiment just now prove? You have no evidence to prove that we did these two children. What's the point of doing this?

After all, taking photos of ghosts is not something that can be done easily."

"It can be photographed." Fūya Rei responded calmly.

"What!" The three men were instantly surprised when they heard it.

Fūya Rei patiently persuaded them: "We only need a dark environment. If you are willing to let us in, there is no reason to refuse unless you have an ulterior motive. If you have done nothing wrong, why don't you let us in?"

Although the sturdy man was nervous, he still pretended to be calm and said, "Then please come in."

When Hagiwara Kenji saw Kudo Shinichi and Mao Lilan preparing to go in, he hurriedly stopped them: "Wait a moment! You two can wait in the car with me. The situation inside is unclear and it may be a little dangerous. It's better not to go in."

Mao Lilan nodded obediently: "Okay, sure."

When Kudo Shinichi heard Hagiwara Kenji's warning about the danger, his eyes swept across the suspicious people in the house who looked panicked, and then fell on the worried face of Mouri Ran.

The detective's sense of mission surged in his chest, and he clenched his fists: "I'm going. I'm a detective! I must find out what those guys are doing and get to the bottom of the truth."

He ran into the house despite being stopped.

Hagiwara Kenji shouted helplessly: "Hey, wait a minute. Why is this kid so stubborn?"

Mao Lilan looked puzzled: "Shinichi? Why is he so impulsive all of a sudden?"

Hagiwara Kenji looked at Kudo Shinichi's back as he rushed into the house with determination, shook his head helplessly, and murmured in a low voice: "Young and energetic boys are always driven by the desire to explore the truth."

The burly man led everyone to the corridor, "What then? What experiment are you going to do at home?"

Furuya Rei calmly replied: "Anyway, please turn off all the lights first."

"Sure." The burly man responded, reaching out to turn off the light, "It will be very dark if you turn off the light."

In the darkness, the faint blue light from the screen of Rei Fōtani's mobile phone suddenly pierced the silence, and the sturdy man's pupils suddenly contracted.

The moment the shutter sounded, Jinpei Matsuda let out a strange cry.

Kudo Shinichi pointed at the photo and blurted out: "This is it!"

"Don't worry." Furiya Rei enlarged the photo. The strange outline that loomed in the shadow made the air freeze instantly: "Do you see this inverted para-real image?"

The flashlight beam shone directly on the wall - the hideous ghost mask cast a distorted shadow under the strong light, perfectly overlapping with the shadow in the photo.

Matsuda Jinpei's eyes flashed with helplessness, and he complained to himself: "Didn't I tell Ogi not to let this brat in?"

Kudo Shinichi was full of doubts: "How did this weird imaging effect come about?"

Pointing to the photo, Rei Furutani explained: "When light passes through the lens, it forms an inverted image and at the same time produces 'secondary reflection' inside the lens, just like you will see multiple shadows of yourself between two mirrors. This will produce overlapping virtual images, which we call secondary real images.

When shooting in a dark environment with strong light, this shadow will be particularly obvious and look like a supernatural phenomenon. "

Jinpei Matsuda stood in front of Kudo Shinichi, squatted slightly, turned on the flashlight, shone the light on his face, and made a scary and funny expression.

Furuya Rei immediately pointed his phone at Matsuda Jinpei and Kudo Shinichi, and snapped another picture. "Usually, when taking photos in bright conditions, these special images are hard to spot. But in a dark place, if you shine a strong light on an object and then take a photo, you can take these seemingly supernatural photos."

"Amazing!" Kudo Shinichi couldn't help but admire the photo in his phone. But a new question came to his mind: "But the ghost face in the photo of us is not upside down? What's going on?"

Fūya Rei turned his head and looked at the burly man. "That must be because he deliberately placed the face-like thing upside down when taking this photo."

He turned on the light and looked at the ghost face on the wall. "For example, a mask like this!"

Kudo Shinichi looked in the direction that Furuya Rei pointed and couldn't help but exclaimed, "That's it. The ghost in the photo looks exactly like this mask."
