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

"What does that no parking sign mean?" Officer Chiba looked puzzled.

I don’t know.” Yumi Miyamoto stared at the signboard, “If there is a connection, it’s that the three people’s names contain red, blue, and white. These three colors just happen to appear on the signboard.”

Sato Miwako looked thoughtful, her right hand gently supporting her chin, "But then it's unclear which of the three people you're referring to."

"I don't know why Yagi came here. Those three people don't live in this apartment." Miyamoto Yumi looked at Officer Takagi, "By the way, did the apartment's surveillance cameras capture anything?"

"This apartment building does not have any surveillance cameras installed. It seems that there are disagreements among the residents, so they did not install them."

Officer Takagi walked quickly to the front of the crowd, looking a little helpless. "Also, someone from the Science and Research Institute just contacted me and said they knew the last phone number Officer Yagi dialed, which was 7155. However, there is no such number and it doesn't work even if you call it."

Officer Shiratori stroked his chin and said, "Maybe she pressed it randomly when she was dying and her consciousness was blurred."

Sato Miwako's eyes were full of determination. "No, she didn't want to make a phone call. She wanted to leave the numbers 7155. Even if the murderer broke the phone, he could still leave a record of the calls."

Everyone fell into deep thought and began to guess the meaning behind the four numbers 7155.

“It doesn’t seem to be the homonym of any word.”

"Maybe it's the song request number of a certain song or something."

Sato Miwako's eyes swept across the crowd, "Do you think that before they were killed, they went to sing karaoke?"

Yumi Miyamoto crossed her arms over her chest and said, "Miike went with them at the time."

Miwako Sato quickly moved closer to Yumi Miyamoto, "Can you call her and confirm this?"

Yumi Miyamoto nodded, reached into her pocket to take out her phone, and looked through her contacts, muttering, "But, she has a bad memory like a cat."

Yumi Miyamoto called Miike Naeko and asked, "Miike, could the number 7155 left by Yagi be the song request number for karaoke?"

Miike Naeko's helpless voice came from the other end of the phone: "How can I remember who sang what song one by one?" Her voice was a little speechless, "Nowadays karaoke bars don't use serial numbers to request songs. In some places, you can even use mobile phone apps to request songs."

Yumi Miyamoto quickly suggested: "If you think of any clues related to 7155, please contact Miwako."

"Okay, I got it." Miike Miaozi said and hung up the phone.

Yumi Miyamoto put her cell phone back into her pocket, bent down to pick up the police hat on the ground, gently brushed off the dust on it, put it on her head, then looked at Kudo Yuki beside her and said, "Xiaoxue, take my police car back." After that, she walked towards the direction of the police car.

Kudo Yuki looked a little worried, "Miwako, I have a favor to ask of you. If anyone sees Conan at night, please remember to contact me."

Miwako Sato patted Yuki Kudo's shoulder and said, "Don't worry, we will keep an eye on it."

Kudo Yuki went to look for Miyamoto Yumi, but when she arrived near the alley, she heard Miyamoto Yumi yawning: "I have to take a nap after I go back."

Kudo Yuki didn't hear any footsteps anymore. She frowned and was about to rush out when she saw two drunkards, each holding a bottle of wine, staggering in front of the police car.

"Hey, you're finally back." One of the drunkards had a tangled tongue and exuded a strong and pungent smell of alcohol.

"We all saw it on the news." Another drunk squinted his eyes and his face turned red.

Miyamoto Yumi rolled her eyes speechlessly, her face full of disgust: "Who are you?"

"I heard that female police officers have been murdered one after another." The drunkard in front of him walked unsteadily, waving a bottle of wine in his hand and shouting loudly.

"We two just helped you protect the police car. Give us some protection money." The drunkard behind them followed suit, his eyes blurry and greedy.

Yumi Miyamoto put her hands on her hips and shouted angrily: "Are you guys stupid?"

The drunk standing in front of him held a bottle and shouted, "What's so arrogant about a little traffic policeman in a short skirt?"

The drunk behind him was not to be outdone, "How can the police say this about us kind citizens?"

As he said this, he was about to swing the bottle in his hand towards Miyamoto Yumi. Just as Kudo Yuki was about to stop him, he saw Morobushi Kagemitsu grab the drunkard's bottle.

"Sorry, you are drunk and acting crazy." Zhu Fu Jingguang was wearing a human skin mask and his voice was processed by a voice changer, so it sounded a little hoarse.

The drunk shouted, "Who are you?"

Zhu Fu Jingguang exerted a little force on his hand and snatched the bottle: "Wake up and don't cause trouble for yourself."

The two drunks were frightened by his aura, sobered up a little, staggered and turned to run away, muttering, "It's our bad luck."

Watching the drunk running away, Miyamoto Yumi breathed a sigh of relief, her eyes fell on Morobushi Jingguang, doubt flashed in her eyes, but soon turned into surprise: "Jingguang, is it you? Although you are wearing a mask and your voice has changed, I can still feel that it is you."

Zhu Fu Jingguang turned off the voice changer: "You still recognized me."

Shushu stuck his head out of Kudo Yuki's pocket to watch the fun, and Kudo Yuki teased, "Tsk, tsk, what a good show of a hero saving a damsel in distress."

Miyamoto Yumi blushed and glared at Kudo Yuki: "Don't talk nonsense."

Kudo Yuki walked up to the two of them with a smile: "But it's really thanks to Hiro's timely appearance. If it weren't for him, who knows what these two drunks would have done."

Zhu Fu Jingguang smiled and made up an excuse for himself, "I was just passing by, and heard the commotion here. I was worried that something might happen to Yumei, and I couldn't help but take action when I saw this situation."

Kudo Yuki sighed deliberately: "Oh, it seems that I have become a light bulb again. The light is too dazzling, I am embarrassed to stay here." As she said this, she pretended to cover her eyes with her hands.

At this time, a breeze blew and ruffled Yumi Miyamoto's hair. She smoothed her hair and said, "Xiaoxue, stop joking with us."

Kudo Yuki blinked her eyes and said, "Okay, okay, I'll leave first and not disturb you two young lovers." After that, she took out the car keys from her pocket and handed them to Morobushi Keimitsu: "Hiro, remember to drive my car back."

Zhu Fu Jingguang quickly took the car keys: "I won't forget it."

Kudo Yuki waved her hand and shouted without turning her head: "Hey, just enjoy your time together!" Her figure gradually walked away.

After walking a few steps, Kudo Yuki's cell phone suddenly rang. She took out her phone and saw that it was a call from Officer Chiba.

"Ms. Kudo, Conan is in Beihua East Park, please come over."

"Okay, I'll be there right away." Kudo Yuki hung up the phone and quickened her pace towards Beihua East Park.

When she ran to the park, she saw Conan holding a skateboard and asking Officer Chiba, "Officer Chiba, are you here to investigate this?"

Officer Chiba leaned forward and said, "Yes, we also found that the second officer, Officer Yagi, entered the numbers 7155 on his phone before he died. I thought there might be clues related to those numbers in this park, so I came to take a look."

Conan fell into deep thought, and Kudo Yuki took the opportunity to make a gesture to Officer Chiba to keep quiet, then tiptoed to Conan's side.

Kudo Yuki bent down slightly, with a half-smile on her face, "Conan, it's already past 8 o'clock, aren't you going home yet?"

"I told Xiaolan that I'll be staying at the doctor's house tonight." Conan grinned and tried to cover up the truth, but his eyes dodged unconsciously. "But my skateboard is out of battery."

Kudo Yuki looked at Conan with a smile, her eyes shrewd, "Conan, am I so easy to fool?"

Conan smiled awkwardly: "Sister Xue, I can't hide anything from you."

Kudo Yuki stood up straight and put her hands in her pockets: "Tell me, Conan, why are you so interested in this case?"

"Sister Xue, I just want to help find the truth."

Kudo Yuki sighed softly: "Conan, this is not something a child can casually participate in."

"Maybe we can find clues that you adults can't find."

At this time, Officer Chiba came over and interrupted: "Ms. Kudo, I think Conan is a smart kid, maybe he can really help."

Kudo Yuki frowned and thought for a moment: "Okay, Conan, but you have to promise me that you will follow my instructions and not act on your own."

Conan nodded excitedly: "No problem, Sister Xue!"

Kudo Yuki smiled helplessly: "Then let's look for clues in the park together and see if we can connect them to the numbers 7155."

Along the way, Officer Chiba was driving the car. "I heard Officer Yumi talk about traffic signs. She said that Japan's traffic signs were based on the UK's."

Conan sat in the passenger seat, looking away from the scenery outside the car window, "Most people don't know."

Officer Chiba looked ahead, his hands firmly on the steering wheel. "Officer Yumi said that everyone in the Ministry of Transportation knows about this. This is common sense, but I don't know if it's true."

Sitting in the back seat, Yuki Kudo's mouth curled up when she heard this, thinking to herself: "So 7155 refers to this, Article 71, Paragraph 5, Item 5 of the Road Traffic Law."

It didn't take long for Conan's little brain to work quickly and he came up with the answer. Just as he was about to speak, Kudo Yuki quickly made a silent gesture, signaling him not to speak yet.

At this time, Officer Chiba's cell phone suddenly rang, and he answered the phone. At first, he heard hurried footsteps, and then 4 knocks repeated 7 times, but no one answered.

After a few seconds, a strange man's rough voice came from the other end of the phone: "Hey, what are you doing? Damn, you actually have two mobile phones."

Immediately afterwards, Miike Naoko's painful groan was heard over the phone.

Kudo Yuki's expression suddenly turned gloomy. "It was Miike Naeko. She was captured by the man wearing a straw hat and a green shirt. If it goes as expected, Miike Naeko was targeted for revenge."

Conan pursed his lips and said with admiration: "Sister Xue, you really do know who the murderer is."

Officer Chiba's hand on the steering wheel trembled slightly, and the car shook: "Are you talking about the murderer who killed Officers Baiqi and Yagi?"

"Yes, Conan also knows who the murderer is." Kudo Yuki asked: "Officer Chiba, do you know why the prohibition signs are represented by circles and slashes?"

Officer Chiba frowned and shook his head, saying, "We still don't know at this point."

Kudo Yuki smiled and gestured for Conan to explain, "That is the shape of the letters N and O combined, which is represented by NO on a blue background. In the common language of this country, the romanization of NO is NO, so the murderer is Mr. Aono."

Officer Chiba frowned, his face full of disbelief: "You mean Qingjia NO is Qingye? Under normal circumstances, would you leave such a clue that sounds like a cold joke?"

Conan said seriously: "I thought the same as you at first, but after looking around the crime scene, the only clue I found was that sign.

The key to leaving clues is to prevent the murderer from discovering the clues, but the clues left behind cannot be completely incomprehensible.

The origin of traffic signs is not well known to ordinary people, but the police from the Ministry of Transportation basically know about it and can easily find it, so it is very suitable to be used as a clue. "

Kudo Yuki sat in the back seat, clapping her hands lightly, a pleased smile on her face: "Conan, you can actually find the key clues by yourself."

"Sister Xue, please explain 7155."

Kudo Yuki gently rubbed Conan's head: "Okay, these numbers 7155 mean Article 71, Paragraph 5, Item 5 of the Road Traffic Law.

Drivers are not allowed to talk on their mobile phones or check their phone screens while driving. This alone shows that the person who was looking at his phone while driving was Aono.

Officer Chiba reported the incident to Kuroda Heibei truthfully. However, Kuroda Heibei did not let him hang up the phone: "Don't hang up yet, Chiba." Then, Kuroda Heibei quickly summoned all police officers to go out.

"I received a call from the Chiba Patrol Chief, and he has identified Kengo Aono as the suspect in the serial murders of female police officers.

All officers, listen up, deploy now and do your utmost to arrest the suspect Kengo Aono. This man is the murderer who killed our two female police officers. We must arrest him at the cost of our police's prestige."

Then, a text message alert sounded from Kudo Yuki's phone. She opened it and saw that it was from Kuroda Heiwei:

Kudo, don't forget to write the report.

A speechless expression instantly appeared on Kudo Yuki's delicate face. She slid her finger across the screen and replied:

Senior, I will give you a report that is worth the money, but not now. I have to rescue Miike Naoko from the Traffic Division of the Metropolitan Police Department. With that in mind, 'It takes a long time for the ice to freeze three feet thick to form'. See you later!

After sending the text message, Kudo Yuki put the phone back into her pocket and prepared to join the rescue operation.
