From Soma Ryusuke's general shouts, everyone understood what had happened.

Ryusuke Soma and Takuru Itakura, both members of the computer club when they were in college, and because they both shared a love of computers and shogi, they wanted to develop a shogi software that could beat celebrities.

(Celebrity, the title of a master of shogi, similar to the dragon king, chess seat, chess king, etc., a total of seven titles, I don't know why there is only one celebrity in the Conan world.) ）

However, this software is not so easy to make, after graduation, Takashi Itakura, who has a higher level of computer skills, became a well-known software engineer and CG designer, while Soma Ryusuke worked in various computer companies and clubs. Twenty years have passed, and during this period, Soma Ryusuke has continued to collect various shogi games and hand them over to Taku Itakura as data support for the software, but the so-called shogi software is still missing.

Until a month ago, Takura Itakura was still patting his chest and swearing that he didn't have any work now and would go all out to develop shogi software, but soon Soma Ryusuke knew that he was also developing Go and chess at the same time.

Compared to the procrastination and prevarication that has lasted for twenty years, what Ryusuke Soma is really angry about is the feeling of being deceived, he feels that he has been deceived and fooled for twenty years.

So he decided to put an end to all this, and took revenge on Itakura Takura for the sake of these twenty years, when he came to visit him two days ago, he gave him a drink of sleeping pills, tied him to a chair when he fell asleep, wrapped him in a quilt and pillow, forced him to cover his heart with his hands when the body was found, turned on the air conditioner to the hottest, and left.

One day later, Takushi Itakura, who was covered in a thick quilt, was "dying of heat" due to a heart attack, and after faking the scene, he contacted two other people who had been released by Takura Itakura, and asked them to go with him to find the location of the detective who asked Takura to help him.

In fact, I don't know where Takura Itakura ran, and it wasn't until a video email was sent that I knew that Takura Itakura was the only one who opened and ran away, Naito Dinghei and Subek Road, as an old friend, in fact, this hotel was selected by Ryusuke Soma for him.

Mizuma finally confirmed the fact that he had changed, and he didn't care about the reason for killing before, but recently he began to listen again and again.

Of course, this time he can also fool himself and say, but because the organization is involved, he doesn't want to let go of a clue before listening to him. But Mizuma Moon was too lazy to lie to himself, he did change, and began to be curious about human nature, wanting to know the reason for people to kill.

Soma Ryusuke wanted to take revenge on Takuru Itakura because he felt that he had been deceived by Takuru Itakura for twenty years, and was dissatisfied with the trampling of his ideals twenty years ago, so he chose to take Takushi Itakura's life.

"That...... It doesn't matter, but the shogi game you want to make is probably that......" Yasuya Yamamoto said suddenly.

"That...... What is it?" Ryusuke Soma's face turned pale, and he suddenly felt that it was not good.

"It's this set of semi-development programs that take up the space of this computer, and I tried to run it, and it looks like a shogi game. Yasuya Yamamoto pointed to the computer and explained, "It does have a lot of game files in its index folder. ”

"Let me see. Mizuma Moon became a little interested, and walked over to fiddle with it.

After Yasuya Yamamoto's point out, Mizuma opened the shogi software.

There wasn't any opening animation or anything like that, and as soon as it was opened, a simple over-the-top board appeared.

Ordinary pure white background, black lines outline the chessboard, the chess pieces on it may be white, obviously Itakura Takura has not done any unnecessary decoration.

"Can you let me take a moment?" Ryusuke Soma said pleadingly, and Mizuma took one look at him and found that his eyes were full of disbelief and faltering.

"Hmm...... All right. "In principle, at this time, we should quickly take Soma Ryusuke back to the Metropolitan Police Department for interrogation, as for the so-called shogi software, whether Itakura Taku does it or not has nothing to do with this case.

The reason why he agreed to try this software was because Mizuma was curious about the future development, and on the other hand, he also wanted to know if there was a chance to defeat the famous shogi software.

Regarding the comparison between humans and computers, Mizuma's position should be regarded as that humans must be better than computers, because even the best machines are man-made, and even if that software really wins the celebrity, it is the software that Itakura Takura made.

"It's really a simple and crude investigation method, Mizuma boy, it's a pity that the deceased left his last words. Uncle Maori came over and spoke to Mizuma.

"Death's last words?'s predecessors' advice?" Mizumatsuki looked at the scene again, but didn't see any death words.

"On that game of chess. Uncle Maori pointed to the Go board on the ground.

"Can you understand it a little more clearly?Is the Maori senior also very proficient in Go?" Mizumatsuki looked at Go, but couldn't see anything, and said with a slight twitch at the corner of her mouth.

"I don't know how to play Go......," said Uncle Maori, "but you see, if you tie the deceased to a stool, you have to fix the stool somewhere else, so that the deceased can't move, otherwise the deceased can struggle to the door and hit the door for help." "It seems that Uncle Maori has taken the topic even further.

"So if you look at this room, the only thing that is suitable for fixing the stool is the table, and if the stool is tied to the table, the deceased's feet can touch the chessboard better, so he used that chessboard to leave his last words. Uncle Maori said eloquently.

"If it were me, even if I couldn't move, I wouldn't give up, and since my feet could move, I would choose to stomp the floor hard instead of fiddling with chess and cards. Mizuma interjected.

"The deceased was old and had heart disease, so he would not be as optimistic as you in terms of physical strength. Uncle Maori explained: "And this is a high-class room in a hotel, and it's hard to expect it to be bad for the silence effect." ”

"What does that have to do with the chessboard?" Mizuma urged Uncle Maori to the point.

"It's about those three people. Uncle Maori pointed to the three men: "Subeklu was the one who commissioned the deceased to make Go software, so he will definitely use Go himself." And that Naito Dinghei, like the deceased, had poor eyesight, so he used Braille in his daily life, that is, Braille. ”

"Go, Braille?" Mizuma became more and more confused the more she listened.

"Two over there, please see if that board is good, from the point of view of Go and Braille. Uncle Maori called the two people who were watching Soma Ryusuke play chess to solve Mizuma's confusion.

"Is this a game of chess? Hey, this isn't Go!" the two of them gave Uncle Maori or Mizuma Moon a lot of face, and walked over to study it, and Subek Lu just glanced at it and said.

"Why? Is it backgammon or reversi?" asked Naito, looking blankly at Subeklu.

"Look at this sunspot, according to the rules of Go, it has been 'dead' and has been 'eaten' by the white. Subecklu's temper was very easy-going, and he smiled and explained Naito's confusion.

"So let all the sunspots be 'eaten', and just observe the whites to see. Uncle Maori commanded.

"According to the words of Braille, the fierce ...... Hand...... Be...... Appearance...... Horse...... Ryusuke! This ...... These are the words left by Itakura-sensei!" Naito read out in surprise.

"I've been taught, and it seems that I will have to use my brain more in the future, thank you Mr. Maori for your advice. Mizumatsuki touched her nose and thanked her with some embarrassment.

Although Uncle Maori is obviously deliberately pretending to show off his IQ, but seeing that Uncle Maori is an afterthought after the case is over, Mizuma Moon doesn't want to hold a grudge.

And......

Before Mizuma Moon could finish his heart, Ryusuke Soma, who was playing a game of shogi there, let out an exclamation: "Win!"

"The computer won?" Mizuma walked over with a question, only to find out that Ryusuke Tokisami had won.

Mizuma asked the police officers who were watching next to him, in fact, Soma Ryusuke and the computer played two games, the first game was Soma Ryusuke lost, and the second game was what Mizuma Moon saw, and the computer lost.

After the last step checkmate, the computer has just been displayed, and the game disappears, and the computer screen returns to that folder, commonly known as flashback.

"It doesn't seem to be done yet, shouldn't there be another game at this time?" Mizuma Moon stood behind Ryusuke Soma and commented.

"It's not that it's not finished, it's that Itakura didn't plan to do what happened after the computer failed in the first place, because we wanted an invincible computer software, not an arcade game that was rotten on the street. Ryusuke Soma retorted unhappily.

"Are you complaining about him, for the person you just killed?" asked Mizumatsuki disdainfully.

"I'm ......" Ryusuke Soma was stunned for a moment, lowered his head, and stopped talking.

"Take it away. "Mizuma Moon feels like there's nothing more to say, so let's let this case end here.

However, Mizuma glanced at the bag in the corner of the room, this thing had to be taken away.
