After a while, Sato Mikako drove to the car.

"Really, I'm still wondering why Takagi investigated so quickly this time. It turned out that it was all based on Conan." She rolled her eyes at Takagi's embarrassed face.

"Not either." Conan waved his hand.

"If this happens, the hot spring bathing matter won't count." Mikako Sato snorted.

"Ah?" Takagi Shiro suddenly felt like he was losing his parents.

"No, just go to the hot spring with him." Azumi said.

Mitsuhiko also agreed, "Yes, the murderer is almost found."

"Don't be so stingy." Yuan Tai muttered.

"Stingy?" Conan's mouth twitched.

"No." Mikako Sato said: "Private emotions are prohibited during the investigation. Don't forget that this is a job that can cause death if you take a wrong step!"

"Oh." Several children nodded honestly.

"Then, I'll drive my own car to take you back." Sato Mikako said: "After you meet with Chiba and the others, continue to search for clues about Guibao Duro."

"Okay." Takagi Suk certainly followed the instructions.

Azumi and others looked at Chen Xing, who was looking down at the side and fiddling with their phones, obviously they didn't want to leave.

"Who are you sending a text message?" Ai Haibara suddenly leaned over and asked.

"A friend." Chen Xing said with a constant expression.

Although Ai Haibara was a little suspicious, he did not ask.

Chen Xing looked at the disappointed children, "Okay, all the little detectives, you have done a good job in investigating the case. Leave the arrest to the police. Let's go home to rest."

Sato Mikako shook her head and smiled, "There is really a way to coax children."

"It seems like we are not capable enough." Takagi Suggi agreed.

Sato Mikako rolled her eyes, "But isn't this what Conan reasoned?"

“…” Takagi Shiro.

At this moment, Mikako Sato received a call from Officer Meguro, saying that Officer Chiba and the others had already caught the person in the apartment of the Horoko.

"You go and invite Mr. Yonggui, the son of Mr. Guoyi, to come here too." Police Officer Memu said.

"Do you want him to identify the voice?" Sato Mikako said, "Because Mr. Nagaki heard the voice of the suspect when he was a child."

"Yes, I'll ask you."

"So Takagi, go find Mr. Nagaki." Sato Mikako said.

"You guys go together." Chen Xing said: "I will drive Officer Takagi's car and take them back."

"Is this okay?" Even though Takagi Suk said so, anyone with discerning eyes could see the joy on his face. After all, he was dealing with his girlfriend.

Sato Mikako looked at him, and the latter immediately said seriously: "Then I'll trouble you. Pay attention to safety on the way."

"So too." Chen Xing nodded.

...

"I didn't expect to catch the serial murderer so easily."

"I thought there would be a more thrilling chase and something like this."

"Or will start a gunfight or something."

The Youth Detective Group expressed disappointment with the murderer this time. It was too weak and not passionate at all.

"Those are only found in movies and TV series." Chen Xing said.

"That's why I'm a little disappointed." Yuan Tai said in an old and angry manner.

In the co-pilot, Conan lowered his head, frowned and thoughtful.

"Is there any other problem?" asked Ai Haibara.

"I still can't understand the word z left on Mr. Pingdong's body." Conan pondered: "On the bodies of the first three victims, it was found that the letters e, s, and w were engraved in the order of being killed, and it should be n in the end."

"Didn't you say before that it is not in the order of east, west, south, and north?" said Ai Haibara.

"That's right, if it's east, west, south, north, it should be the order of e, w, s, n." Mitsuhiko said.

"No, if it is to say mahjong, it should be southeast, southwest and northwest." Conan said: "But why is it z in the end?"

"Would you plan to put the body horizontally after committing the murder?" Mitsuhiko said, "It's n if you come across it."

"Since that's the case, why didn't the body come across?" Yuan Tai asked.

"This..." Mitsuhiko tentatively awkwardly: "Are you too anxious and forgot?"

"Please, he has killed three people, are you still anxious?" Yuan Tai is very good at attacking his friends.

Mitsuhiko's face turned red and she stopped talking.

"There are also the ctrl and c keys left by Mr. Pingdong. These two keys are obviously intended to express 'copy'." Conan held his chin, "But why did he hold the mouse again?"

At this time, he heard a lightly read syllable, "copycat."

"What?" Conan was stunned, and a flash of inspiration flashed through his mind.

What Haibara Ai noticed was that when several children were speculating, Chenxiong received a text message.

"I understand, so that's it!" Conan said calmly with a smile: "Ghost Bao Dulang is not a serial murderer."

"What's going on?" Yuan Tai said puzzled.

"Because Mr. Pingdong himself is a criminal psychologist, he should be very clear about what kind of person he is. In addition, the two of them had fought in the mahjong hall, which really makes it hard to imagine that they would agree to meet alone in private."

Conan said: "And the death message left by Mr. Pingdong should mean to mean that the one who killed him was not the serial murderer. The blood stained are the ctrl key and the c key, which means copying. As for the mouse line in the hand, it means the cat that grasps the mouse tail, and it is put together..."

"copycat." Haibara Ai whispered.

"Yes, this is the murder case committed by imitating the techniques of serial murderers!" Conan said.

"Imitationist? Does this have anything to do with bibimbap?" Yuanta's words completely dispelled the original atmosphere.

"What?" Mitsuhiko said seriously: "I think it might be talking about the cyan mole behind the baby's butt."

"That's called Mongolian Madara." Haibara Ai couldn't help but interrupt the increasingly outrageous speculation. "The so-called imitation criminal means imitating the techniques of famous murderers to commit crimes."

"But why is it a cat?" Azumi asked.

"Because the kitten can imitate the behavior of big cats, he said that." Haibara Ai explained.

"But how could Mr. Pingdong know that this was done by the imitator?" asked Mitsuhiko.

"The reason he said this is because Mr. Pingdong, who was killed, was the serial murderer!" Conan said in a shocking way.

"Ah?" Several children were startled.

"If you make this inference, you can imagine the intention of Mr. Hirado's z-shaped marks on his back." Conan said: "Because there was a long one-shaped knife wound on the back of the serial murderer who was cut by Police Chief Matsumoto. In order to cover up the scar, the murderer did not see that Mr. Hirado might be the murderer of the serial murder case, so he carved the letter along the old wound."

"In this way, the police will continue to investigate the dead serial murderers, and they will never be included in the search." Haibara Ai said thoughtfully: "Who will he be?"

"You and Ayumi passed by him and heard him whistle," Conan said.

Haibara Ai woke up and realized: "So he would play that song too!"

Conan nodded, "That's right, it should be someone in the victim's family."

"Who is that?" Arimi rubbed her arms.

"If it is the victim's family, everyone should know that the victim's body has letters engraved on it, but there is only one person who knows that the murderer will whistle and that he usually uses mahjong language." Conan's tone was condensed.

"Is it..." Ai Haibara said in surprise: "Mr. Nagaki Kuroi who was in the same room at the time of the incident?"

"Yes, because only he knows the voice of the murderer. He heard the voice of Mr. Pingdong who often goes on TV and his way of speaking, and began to have some doubts. So he found out one by one the mahjong halls his father might go to, confirmed the relationship between the three victims and Mr. Pingdong, and confirmed that he was the murderer of the serial murder case."

"It took fifteen years to get to this point because Mr. Yonggui only realized that it was a mahjong term when he grew up."

"Mr. Yonggui is the fierce person when we visited before, right?" Yuan Tai asked.

"Fortunately, Officer Takagi was not alone just now." Mitsuhiko breathed a sigh of relief.

"Yes, if Officer Sato is with you, you will definitely be fine." Ayumi said.

Having said that, they don't know the truth of the case yet, and even two people can be dangerous.

"Chenxun, we'll rush over, too." Conan said, not forgetting to take out his cell phone to notify the police.

"Don't worry." Haibara Ai smiled faintly, "This road should not be the way to send us home, right?"

"Eh?" Conan was stunned.

Haibara Ai looked at the person who was focusing on the road ahead and driving silently. After he received the text message, he had already changed his route.

"So that text message told him the truth of the case and who the murderer was." She couldn't help but wonder, "Who would the person who sent the text message?"
