In Room 2004 of the Rice Flower Hotel, Mr. Itakura's body is being used by the police for further testing.

Conan looks at Officer Twilight's USB flash drive, anxious. I thought to myself, "No, I must get the USB flash drive, I must see what the hell they are going to do!" ”

Conan felt that all three of them were suspicious at this time, but when he watched them pretend not to know anything, he planned to find some clues from the chess pieces next to the bed.

"Officer Twilight, you see he has strangulation marks on the top half of his left foot, but not on his right leg."

Officer Twilight walks over with interest. Sure enough, then what's going on?

"But there are still strange scratches."

Conan suddenly discovers a strange Go board. Although there are special symbols on it, it also proves that as long as you crack Mr. Itakura's code, you will be able to lock the murderer completely.

When they feel that they can't find any valuable clues, Officer Twilight says, "Let's take Professor Itakura's body back to the police station first."

After receiving the instructions, the forensic officer carried Professor Itakura's body to the police car for further testing.

Officer Takagi then handed over the USB flash drive used as evidence to Officer Takagi and asked him to keep it. It is then handed over to the forensic team.

Officer Takagi said that I would take good care of it.

Officer Twilight then proceeds to ask, "It seems that according to the last words of the deceased, the three of you are indeed suspicious." Let's talk about it. ”

Mr. Sube explained, "I asked Professor Itakura to design the Go software. My name is Subei. ”

Mr. Naito, who was wearing glasses and dark gray, also replied, "I am from a different company than the two of them. I approached him to design chess. ”

Ryusuke Soma said that I was the one who asked him to design chess.

Mr. Naito anxiously said that I have something to do, can I leave first? If there is any progress, can you ask again tomorrow?

Mori Kogoro felt like he had a busy day, and he wanted to slip away.

Officer Twilight feels like this isn't the way to go. After all, it would be a waste of everyone's time to spend it here, and then it means that you can register your personal information and leave.

When Kogoro Mori wants to tell Officer Twilight if I can go back, Conan imitates Kogoro Mori's voice and says something incredible.

"Mr. Officer, all three of them are still suspicious. You can't let them go. ”

Officer Twilight looks at Mori Kogoro speechlessly.

Of course, Mori Kogoro said that I just want to go home and watch Yoko Okino's concert, how could I say such a thing?

Conan knew that his watch-type tranquilizer gun was about to play his role again, so he gave Mori Kogoro a try.

"Because the killer is..."

Officer Twilight looked at Kogoro Maori, who was lying on the bed unconsciously, and asked with concern, "Are you okay, Brother Maori?" ”

"No, I'm fine. Let's take a look at today's case first. Also, the murderer is laughing at your incompetence among the three of them. ”

Officer Twilight was furious when she saw that Mori Kogoro dared to say that about him. He yelled at him, "Brother Maori, if you don't tell me why, I will never let you go." ”

"Of course I know who the killer is. Because the murderer told us the answer. It's on this chessboard. ”

Officer Twilight and Officer Takagi are immediately speechless.

"If you don't believe it, just look at that Go board. And his ankles. Because that mark could be a sock mark. So..."

Officer Twilight looks at Mori Kogoro who is deliberately selling off the gate and asks, "So tell me what the hell is going on." ”

"Because he can't do things like arrange things or anything else that would suggest the murderer."

Officer Twilight is increasingly puzzled by what Mori Kogoro wants to say. What does this have to do with wearing socks?

Officer Takagi looked at the chessboard next to the bed and asked, "Are you talking about the chessboard?" ”

"That's right, I'm talking about the chessboard."

"He used his right foot and corrected himself!"

Officer Twilight doesn't understand what the chessboard means.

Kogoro Maori asks Officer Twilight to do what he asks.

Officer Twilight, however, apparently doesn't use a laptop.

With Officer Takagi's help, Officer Twilight finally learns how to operate a computer.

Officer Twilight asks, confused, "What the hell is this for?" Are you playing me like a fool? I know I can't play on the computer. ”

"Finally, you just power off your computer."

But for some reason, Officer Twilight can't turn off the computer. Officer Takagi tried to help, but was stopped by Kogoro Mori.

Enraged, Officer Twilight decides to pull the plug. But he didn't know that the laptop had a built-in battery, so it would still work properly after being unplugged.

Officer Twilight angrily asks, "What do you want to do!" Don't play me for a fool. I'd better take a closer look at what the hints are on this board. ”

After saying that, he left the computer desk and walked to the chessboard where the game of Go was placed.

Officer Takagi knows why Officer Twilight is angry. He explained: "In order to ensure the security of the computer and the data of the computer, if you want to shut down, in addition to directly clicking the shutdown button on the desktop, you can press and hold the power button of the computer for about 10 seconds." ”

"Officer Takagi is absolutely right. Also, it is impossible for someone who is not computer proficient to know what is written on the chessboard. So..."

Officer Twilight looks at the code on the chessboard, saying she doesn't understand it.

But Mr. Sube saw a clue. Because he found that the black piece surrounded the white piece, and the white piece should be counted as death and taken by the opponent, but he is still here. This does not comply with the rules of Go.

Officer Twilight asks, "What does that mean?" ”

As Officer Twilight and the others discuss the rules of Go, Conan quickly removes the duplicated USB stick and puts it in his pocket.

But this move was discovered by Xiaolan.

Conan hurriedly said that he had not done anything.

The attentive Maolilan certainly knew that Conan was lying. So he continued to ask: "I know what you want to do, hurry up and tell the truth." ”

Conan quickly changed the subject and said, "Why do you think there are some strange stickers on this keyboard?" ”

Mao Lilan was puzzled and asked, "This can't have anything to do with the chessboard, right?" ”

Officer Takagi suddenly remembered something and said, "It's not a Braille technique. ”

Mr. Naito suddenly discovers that if you only look at the black chess pieces, you will find that "the murderer is Soma Ryusuke." The proof of this is his watch. ”

Ryusuke Soma wondered, "Why can't it be Mr. Subei?" He's the one who asks for Go software. I'm chess, so I have nothing to do with him. ”

Mr. Subei knew that he was not suspicious, and hurriedly said: "You are talking nonsense, if I am the murderer, then why does Braille say that it is me, not you!" ”

"That's right, Professor Itakura just uses an input method that you don't know Braille, so..."

Still confused, Officer Twilight asked, "Brother Maori, can you tell me about your evidence?" You're going too fast. ”

Conan knew he was in a hurry. So I forced myself to calm down.

When he calmed down, he began to say, "Because I know that the murderer knows that he will definitely come back, I must have left the secret number of the murderer's name." It's to expose you by taking advantage of your inability to read Braille techniques. And Mr. Subei and Mr. Naito can understand the content of Braille, so they use Go as the best proof to expose that you are the murderer! The police will use the chessboard and..."

Officer Twilight still doesn't understand. Q: "What does a watch mean?" ”

"Look at his watch, because it's a new one. Mr. Itakura must have seen your watch, so your watch must have his fingerprints. So..."

Officer Takagi suddenly realized and said, "In that case, I think you should cooperate with our investigation." ”

Ryusuke Soma knew he had nothing more to say, so he handed his watch to Officer Twilight and them.

Officer Twilight still doesn't understand his actions and asks, "Why did you do that?" ”

Ryusuke Soma said angrily, "While he was looking at my watch, I was fascinated by drugs for insomnia, and..."

Then, after looking at their eyes in disbelief, he continued: "At that time, he was just an ordinary programmer like me. We were in the same company at the time, and we started out as chess friends, but when I met him three days ago, he said to me that he was using me as a stepping stone. I collected no less than 10,000 chess games for his dream, but he..."

When they listened to Ryusuke Soma's explanation, they took him away. After looking at the lonely back of Soma Ryusuke, I was full of emotion.

After they left the hotel, Mao Lilan asked Conan uneasily, "What the hell are you talking about Shinichi?" Will our relationship be..."

After listening to Mao Lilan's complaining attitude, Conan said comfortingly: "Don't worry, the new brother has definitely not changed, and he is still a heart for you." As far as the last birthday is concerned..."

So what exactly did they say, and will Maoriran change his mind about Shinichi? What kind of confrontation does Conan have with the Black Order...
