Conan: Above force, everything is truth!

After seeing Maori Kogoro's eyes asking for help, Tatsuno blinked helplessly.

Although he didn't know why he asked for help, he was Xiaolan's father anyway.

Tatsuno secretly told Xiaojia to mark the death locations of the six victims on the map, and then analyze the possible meaning of the "English letters" behind the mahjong tiles based on this.

But then again, combined with Uncle Maori's previous performance, Tatsuno couldn't even tell whether he was really "stupid" or wanted to take the opportunity to test himself.

Thinking of this, Tatsuno stood up and chuckled: "Uncle Maori, everyone. Next, please listen to my guess."

The attention of everyone present was instantly focused on Tatsuno.

Except for a few people, most police officers had never seen Tatsuno, let alone why this young man was a "special consultant".

Therefore, seeing this young man stand up, everyone was very curious.

Under the gaze of everyone, Tatsuno slowly walked to the writing board on the stage.

The next second, Ryuno put away the smile on his face, and his momentum changed significantly: "Everyone knows that the appearance of these mahjong tiles indicates that there may be a certain connection between these victims."

"Since the sixth victim, Ryunosaki, left a death message - 'Tanabata, Kyoto'. I suggest that you start from here and investigate whether the victims went to Kyoto at the same time on the Tanabata day in previous years."

Speaking of this, Ryuno turned to look at Officer Shiratori: "Officer Shiratori, please help me call up the map."

Hearing this, Officer Shiratori immediately displayed the map on the whiteboard next to him.

Ryuno nodded to express his gratitude, then turned and walked to the whiteboard, and picked up the stylus next to him.

"Why did the criminal go to so much trouble to tie the victim to a fixed location before killing him..."

Tatsuno circled the death locations of the six victims with a pen, and then connected the dots: "The murderer did this to complete this pattern."

The police officers looked at the broken line pattern on the map, all puzzled.

"Brother Tatsuno, what is the meaning of this pattern?" Inspector Megure tilted his head and said.

Tatsuno nodded slightly and continued: "If you want to know the meaning of the pattern, you must combine it with the English letters on the mahjong tiles... No, it should be the Greek letters."

"Greek letters?"

Inspector Megure and the police officers in the audience all showed a thoughtful look.

Not long after, Saitama Prefecture's Inspector Ogino Ayami suddenly raised her hand: "Could it be that these letters represent stars?!"

Tatsuno nodded, turned around and wrote Greek letters next to each point on the map with a pen: "Yes, the letters behind the mahjong tiles represent: Ursa Major Alpha, Ursa Major Beta, Ursa Major Gamma, Ursa Major Epsilon, Ursa Major Zeta and Ursa Major Eta... the so-called Big Dipper!"

Hearing this, the police officers in the audience showed shocked expressions.

Just as everyone compared the Greek letters on the mahjong tiles with the corresponding stars one by one, Tatsuno marked another point on the map.

After finishing all this, Ryuno put down the pen in his hand, turned around and said: "The seven barrels on the mahjong tiles represent the Big Dipper. And now, the only letter that has not appeared is the letter representing the δ of Ursa Major."

"That is to say... the next crime scene of the criminal should be here!"

After seeing the location of Ryuno's finger, Inspector Megure stood up: "Hachioji City!"

"That's right! Next, please start investigating from this direction: the connection between several victims and Tanabata Kyoto." Ryuno said lightly.

As soon as Ryuno finished speaking, the police officers in the audience subconsciously answered in unison: "Yes!!!"

Ryuno: "???"

The next second, the police officers in the audience realized that the person standing on the stage was not their superior, but an ordinary high school student.

For a moment, everyone looked at Inspector Megure and Manager Matsumoto on the stage embarrassedly.

After seeing this, Inspector Megure stepped forward and patted Tatsuno on the shoulder, saying, "Hahaha, you are worthy of me! I think your reasoning is very correct!"

After saying that, Inspector Megure glanced at Manager Matsumoto behind him.

Manager Matsumoto immediately stood up and said, "Tatsuno-kun is right! Next, we will focus on investigating this direction!"

"Please listen carefully, according to Tatsuno-kun's reasoning, the murderer is likely to commit crimes again! This matter is related to the prestige of the police. There are no victims in Hachioji City yet, and we must take precautions before it happens!!"

——"Yes!!!"

...

After the meeting was dismissed, Tatsuno walked to Xiaolan's side.

"Xiaolan, guess who I saw?"

"Huh?" Xiaolan blinked in confusion."Ms. Yui~" Tatsuno chuckled.

"Eh?! So, Miss Yui has already?!" After hearing this familiar name, Xiaolan's eyes widened instantly, her face full of joy.

At this moment, Officer Yamato and Officer Yui walked up to the two of them.

Officer Yui greeted Xiaolan happily, then turned to look at Tatsuno and sighed: "Although I thought so last time... You are really amazing!"

"Yeah! No wonder Inspector Megure always mentions you, your reasoning really opened my eyes!" Officer Sato and Officer Takagi also came over and exclaimed.

If they were not in a meeting just now, they would have wanted to get close to Tatsuno and ask him how he analyzed the case.

Conan on the side looked at Tatsuno as if he was looking at a monster.

Because of the bug, Tatsuno's words entered his ears word by word.

Although he had known that Ryunosuke's reasoning ability was excellent, the reasoning just now was simply... He even thought that Ryunosuke was the serial killer!

Just then, a police officer wearing glasses looked at Ryunosuke a few times from a distance, and then turned and left.

After noticing this sight, Ryunosuke glanced at "his" back, and the corners of his mouth slightly raised.

...

Evening

Conan walked to a place not far from Ryunosuke's house and called Ryunosuke out.

Although Conan hadn't spoken yet, Ryunosuke had guessed his intention and spoke first: "You want to discuss with me the text message sent by Teacher Judy, right?"

Conan nodded: "Yes, Vermouth is likely to have returned here, we..."

"She is at today's search meeting." Ryunosuke interrupted before Conan finished speaking.

Hearing this, Conan opened his mouth instantly and looked at Ryunosuke in horror.

"She must have disguised herself as a police officer. After the meeting, I saw a police officer walk out of the Metropolitan Police Department and get into a black car. If I'm not mistaken, the person sitting in the passenger seat should be Gin." Ryuno continued.

Hearing this, Conan's scalp tingled and he was completely stunned.
