\"Could it be that John has been drugged?\" Conan asked hurriedly as he waited for Twilight to sit on the couch as he watched as Twilight came to visit.

"Don't worry, Conan.We'll bring it to the bureau, it's not yet 'sentenced', don't worry.\" Twilight replied with a smile as she held her teacup.

"Officer Twilight, Mr. Sakaguchi, what did he say?\" Mori asked Twilight on the other side.

\"Well, he didn't believe John would attack people casually.\" Twilight replied with her hands folded.

"Yes, I don't believe it either, there must be a reason for this.\" Conan said hurriedly.

\"You give me a little quiet.\" Maori said while holding Conan's head with one hand and holding Conan's chin at the same time.

"I'm sorry, Officer Troublesome continued.\" Mori smiled sheepishly and smiled at Twilight.

First of all, I asked Mr. Sakaguchi what he said to Xiao Gang on the phone, and he replied like this.\"Is there anything wrong\" and then \"Could you please call John to answer the phone\" and then he said that it is customary to say good night to John before going to bed, and before saying good night he said "John, how are you, how are you, John\", and then he said that he heard John barking wildly.\" Twilight continued as he flipped through his police manual.

"Well, this order is really strange.\" Xiaobai listened to the last sentence, which was a strange order, and it was also a sentence that made people feel very out of tune.

"Did Mr. Sakaguchi say anything else?" Mori continued.

"Yes. That's right, I asked the assistant who was in the house with me...\" Twilight continued to say something to Maori.

\"Sister Lan, do you remember what you said last night?\" Conan asked with his hands in his pockets as he asked Ran, who was holding the tray on the side.

\"Huh?\" Ran looked at Conan.

\"You said Mr. Sakaguchi's son killed himself.\" Conan said as he looked at Ran.

\"Hmm.\" Ran replied.

\"So, did Mr. Sakaguchi train John because he wanted revenge?\" Megumi on the side looked at Conan and asked.

\"I've heard from my colleague about that too.\ It seems to be because of being bullied by a classmate.\" Conan didn't answer Megumi yet, but Twilight thought about it and said.

"Well, she seems to care about John very much.\" Xiaobai looked at the worried eyes of Xiao Hui on the side and thought, it seems that Xiao Hui also likes John.

"Could it be that the person who bullied his son at that time was Xiao Gang?\" Maori asked hurriedly.

\"Don't worry, John will be fine.\" Xiaobai walked up to Xiaohui, patted her shoulder, and whispered in her ear.

\"What you said is true?\" Xiaohui looked at Xiaobai excitedly, because the voice was too loud, everyone's eyes looked at them.

\"Let's continue to listen to what Uncle and they have to say.\" Xiaobai gave her a reassuring expression, and then said to Megumi.Then he looked towards Twilight, and he felt that things were about to come to light.

\"Xiao Gang and his son Masato are classmates in the country, and Masato wrote in his diary that he was bullied by Xiao Gang, and committed suicide because of it.\ Sakaguchi read Masato's diary, he must have hated Xiao Gang very much, and Sakaguchi's wife died very early, and Masato is his only relative.\ But during the wake, he saw Xiao Gang who kept crying and making amends, and still forgave him.\" Twilight took out his police manual and looked at it and said.

\"Was Xiao Gang the only one who bullied his son Masato at that time?\" Maori asked.

\"Seems to be so.\" Twilight replied looking at the police manual.

\"Shortly after that incident, Koyoshi transferred to Kansai because of his father's work.And then two years ago, Koyo returned to Tokyo after being admitted to a university in Tokyo, and moved next door to Mr. Sakaguchi this spring.\" Twilight replied as she looked at Maori.

"Oh, it seems that the gears of fate are really turning, it seems that the problem has happened in the past few months.\" Xiaobai thought after listening to Twilight's answer.

"Mr. Sakaguchi didn't expect to see Gang again, and seemed to be taken aback., but he seemed to have forgotten about the past, and often invited Gang to his house for dinner.\" Twilight continued to add.

\"It seems that it is enough, then it is only the time left for training.\" Xiaobai thought, and ran forward.

\"Officer Twilight, may I ask if Mr. Sakaguchi has often taken John out for walks or games these months?"

We asked him and his neighbors about this, and according to their confessions, Mr. Sakaguchi had taken John out in his car every Sunday for the past three months.\" Twilight said as she flipped through the police brochure again.

"Officer Twilight, he must have used this time to train John.\" Maori said as he heard Twilight's reply.

"Unfortunately, but we don't have any evidence.\" Twilight said, putting the police manual back in her chest pocket.

"Everything is clear...\" The corners of Xiaobai's mouth rose slightly, and then walked towards the door.

Sakaguchi Yoshiotaku

\"Did you think of anything?\" Conan and Xiaobai stood in front of the door, and Conan, who pressed the doorbell, asked Xiaobai on the side.

\"Well, it's okay.\" Xiaobai smiled.

\"It's okay, what do you mean...\" Conan squinted at the dead fish and looked at Xiaobai.

\"Oh, it's Conan and Shiro.\" The door opened, and Sakaguchi looked at Conan and Shiro and said.

\"Excuse me.\" Conan and Xiaobai said at the same time.

\"Hehe, it's okay, you guys come in.\" Sakaguchi smiled and welcomed Conan and Shiro in.

"Come, drink juice.\" After entering, Sakaguchi poured two glasses of juice, one in front of Conan and one in front of Xiaobai.

\"Thank you, because I think John must be lonely when he is not there.\" Conan said as he looked at Sakaguchi with his hands on the sofa, and as for Xiaobai on the side, he picked up the cup and held it in the palm of his hand and took a sip.

\"Thank you so much.\" Sakaguchi replied with a smile.

\"Uncle, John, does it sleep on the stairs every time?\" Conan asked, looking upstairs.

\"Yes, that's right.\" Sakaguchi was stunned for a moment, then turned his head to look upstairs and replied.

"Why doesn't it sleep underneath?" Conan asked, looking upstairs.

\"It's my son's room up there.\" Sakaguchi replied as he looked upstairs, and his eyes carried a sadness.

"My son likes John very much, but he doesn't allow dogs in the room until his mother dies, so just let John sleep at the door.Although it's been eight years now, John is still waiting for my son to open the door and say good morning to him every morning.\" Sakaguchi answered Conan's question wistfully.

\"...\" Xiaobai was listening to Sakaguchi's answer while looking at the phone in the distance and thinking about something, but after hearing Sakaguchi's answer later, he held the cup with his palm and seemed to be very angry.

"What's wrong?\" Conan asked softly as he sensed the difference in the people around him.

\"Uncle, you better go and turn yourself in.\" Xiaobai put the cup on the table and said to Sakaguchi.

\"Huh?\" Conan and Sakaguchi both looked at Shiro.

\"Don't you think it's too much to use John to help you kill someone?\" Xiaobai looked at Sakaguchi and asked.

"What do you say...\" Sakaguchi said with a wave of his hand.

\"I'm so sorry I don't bother.\" Xiaobai jumped off the couch and walked towards the door.

\"I'm sorry.\" Conan also apologized and caught up with Xiaobai's footsteps.

on the road

\"What's wrong?\" Conan asked, looking at Xiaobai.

\"John is very pitiful.\" Xiaobai said, looking up.

\"Huh?\" Conan looked confused.

\"Being used by the master to kill the other party, and John has been guarding that home...\" Xiaobai looked at the clouds in the sky and replied in a low voice.

"Do you know something?" asked Conan, too.

\"I don't think you'd be hard to guess.\" said to Conan with his hands in his pockets.

\"Well, probably.\" Conan replied.

Māori Detective Agency

"The microphone is different?\" Ran asked Conan.

"The main unit of the wireless phone is a wired microphone, but last night I only put the handset in the living room, why is that?\" Conan returned to the office and told Mori and Ran what he saw at Sakaguchi's house.

\"Strange, why do you do this, it's really hard to figure out.\" Xiaolan thought about it and felt puzzled.

\"There must be a reason for this, I guess Mr. Sakaguchi must have used a wireless phone to convey orders.\" Maori stood up and said when he heard Conan's confusion.

\"What do you say Daddy?\" Ran asked, looking at Maori.

"Come to think of it, it's impossible to get a wired microphone to the second floor, so Mr. Sakaguchi put the wireless handset microphone in the living room.\" Mori replied.

\"So Dad, do you think Uncle Sakaguchi told John to attack Gang?\" Ran asked as she walked up to Maori.

"The phone call made me even more convinced, but I didn't know what that important attack code word was.\" Maori said as he hammered down the table.

"Our house clock won't ring.\" Conan said, pointing to the clock.

"Huh?\" Maori and Ran looked at Conan.

"But the bell in Uncle Sakaguchi's house rings every hour.\" Conan replied.

"Clock, by the way.John attacked Xiao Gang when it was exactly nine o'clock, I see, Detective Mori Kogoro easily solved the puzzle.\" Mori said in surprise at the thought of something, and then laughed excitedly.

And on the side

\"Is this really going to end like this?\" Xiaohui asked Xiaobai.

\"Well, that's what Conan said, so don't worry, John will be fine.\" Xiaobai replied with a smile on his hands in his pockets.

\"Hmm.\" Megumi nodded.

Rice Flower Police Station

"What the hell are you trying to say?" Sakaguchi looked at John not far away in a cage, and Mori and a member of Twilight's assistant asked Twilight suspiciously.

"We'd like to do an experiment, Mr. Sakaguchi.\" Twilight replied.

\"Now please follow my instructions and repeat what I said to John last night.\" Twilight ran to John's side and looked at Sakaguchi and said.

"This...\" Sakaguchi said as he looked at Twilight with a worried look in his eyes.

"No, it's the wrong step.\" Shiro thought as she watched Twilight pull out a bell from a tape recorder.

\"Mr. Sakaguchi, please get started.\" When the bell was finished, Twilight said to Sakaguchi.

\"Okay... How are you, John, John.\" Sakaguchi looked at John as he spoke, but when he finished speaking, John didn't move.

"Louder, Mr. Sakaguchi.\" Twilight said loudly to Sakaguchi.

\"Officer Twilight, even if he thinks it's useless to be louder.\" As Sakaguchi was about to repeat it out loud, Shiro stepped forward and said.

\"Huh?\" Everyone present looked at Xiaobai.

"Maybe Uncle Maori didn't make it clear just now, you're missing a step.\" Shiro said as he looked at Twilight.

\"Steps?\" everyone wondered.

\"Yes, the one that's missing, it's the beginning... Wireless phone.\" Xiaobai stepped forward and turned around, then looked at Sakaguchi and said.

\"Hmm...\" Sakaguchi looked at Xiaobai in shock, and his worried eyes became even more intense.

\"By the way, Miss Sanae Sugi also said that the bell rang after Xiao Gang answered the phone.\ Then this tragedy occurred when John was listening to the phone.\" Maori thought of something and hit his left palm with his right hand and said.

"Hmm.\" Twilight winked at his assistant, who immediately went to prepare two wireless phones.

"Okay, let's do it all over again.\" When everything was ready, Twilight said to Sakaguchi.

\"...\" Sakaguchi nodded in a smugh.

\"Hey, hello.\" As Twilight dialed another wireless phone, the phone rang, John seemed to hear something and stood up, while the assistant pressed to answer the phone.

\"Effective.\" Conan thought as he watched John's movements.

\"All in place.\" Xiaobai looked at John who stood up, and counted in his heart.

Then Twilight pressed the tape recorder and the bell rang out.

\"Ready.\" Xiaobai looked at John, who bared his teeth and attacked, and continued to count in his heart, while Maori and the others on the side looked surprised at John's movements.

\"Well, please say that again.\" Twilight said as she handed the wireless phone to Sakaguchi.

\"I pleaded guilty.\" Sakaguchi took the phone, watched the assistant not far away put the wireless phone to John's ear, wanted to say something but couldn't, and finally closed his eyes and confessed his crime.

\"Mr. Sakaguchi, do you admit that you trained John to attack Tsuyoshi.\" Twilight asked.

\"Because... Xiao Gang doesn't even remember that incident at all.\" Sakaguchi said with his head down.

\"...\" Twilight looked at Sakaguchi suspiciously.

\"My business, the business of the righteous man, he didn't remember anything about forcing a man to die.\" Sakaguchi's eyes twitched as he thought as he replied.

"That's why he moved next door unconsciously.\" Maori said when he heard Sakaguchi's reply.

"I am a full-time lawyer for juvenile issues, and what I do is to correct the misguided juveniles.So eight years ago, I saw Xiao Gang crying so sadly in front of the righteous soul, and I thought to myself that he was just a child after all, and he had a heart of reflection, so I forgave him. Who knew that when I saw him again eight years later, Xiao Gang didn't remember this incident at all, and he hadn't changed since eight years ago... I thought to myself, is the death of a righteous person worth it or not, is it true... Do I want to continue to forgive this kid?, so I...\" Sakaguchi said as he looked at his trembling hands.

"So you're using John.\" Twilight said, looking at Sakaguchi.

"Yes, if the law can't punish him, I'll punish him with justice. John, and it must be glad it can...\" Sakaguchi continued loudly.

\"Do you think that's the right thing to do?\" As Sakaguchi wanted to continue, Xiaobai's angry voice came.

\"Uh?\" Everyone present looked at Xiaobai, however, there was a girl who was looking at Xiaobai's angry expression worriedly.

"Don't you understand, why does John keep standing guard at the door of Masato's room?" asked Sakaguchi in a loud voice.

\"Who said I didn't understand.\" Sakaguchi retorted loudly.

\"Now that you understand, have you considered its feelings?Have you considered its feelings?Have you considered its feelings?For the death of the righteous man, not only you are sad, but it is John who is even more sad.For eight years, you have been waiting in front of the door of the righteous person's room, but you can never see your master again, have you considered it? You keep saying that it is for the revenge of the righteous person, but you use John to help you complete the revenge, and if you have the ability, you can do it yourself.\" Xiaobai roared angrily, not caring at all about the presence of Maori and the others.

\"Xiaobai...\" Xiaolan walked over and squatted down to hug Xiaobai's head, letting him lean against his chest.

\"...\" Xiaohui also stepped forward and put his hand on Xiaobai's shoulder.As for Conan, he also looked at Xiaobai worriedly.For Xiaobai at this moment, everyone felt very unfamiliar.For Xiaolan and Maori, this is the first time to see Xiaobai angry, but for Conan and Xiaohui, this is the second time.

\"John still trusts you so much and admires you, don't you understand?\" Conan released John, only to see John run to Sakaguchi, sit down and wagged his tail and stuck out his tongue to look at his master, and Maori on the side looked at the scene at this time and said.

"John, I'm sorry... John, please forgive me... John.\" Sakaguchi hugged John, crying and screaming.

End:

Arrested because Sakaguchi confessed to his murder, John was handed over to Sakaguchi's relatives for adoption.

As for what Xiaobai said at the time, Maori and others kept their mouths shut about it.
