Why are there so many suspects this time?... After scanning the list, Ye Gengyi quickly calculated the number of people above:

“Fifty-eight.”

Eh?

This is just turning his fingers. Memu Thirteen, who had just counted to 3, froze and was a little confused. He didn't know whether to believe it or pretend not to hear it and continue counting...

Seeing this, Ye Gengyi said:

"Standard A4 paper, No. 3 font, visually estimated that the upper margin is about 3.7 cm, the lower margin is about 3.4 cm, and 1 times the row spacing. Each column has a maximum of 20 rows. There are two names missing in the third column, so it is 58 people."

Meguchi Thirteen: "..."

Ah, this... Before, Teacher Judy taught himself English, and later, another brother taught himself to calculate...

(╯‵□′)╯︵┻━┻

What's wrong with not studying hard? Have you eaten your rice?!

"Ahem... there are indeed fifty-eight, but it's not easy to filter these people one by one." On the side, Takagi coughed twice, smoothing out the field for his own police department and changing the topic.

"If you screen the suspect, let Officer Sato go. Takagi, go to the forensic officer to ask, have the deceased's fingerprints identified?"

Megu Thirteen folded the list and handed it over, and got up and walked out of the coffee shop like a ok of nothing.

Officer Sato?

Chiba and Shinobu, who were beside him, silently took the list.

She interrogated the prisoner in the Metropolitan Police Department, but she didn't come...

The Meguro Police Department must be very embarrassed now... The others looked at each other and reached a consensus.

......

Everyone came to the escalator again.

A little while.

Takagi trotted back and whispered: "The forensic officer has confirmed that the fingerprint of the deceased was indeed detected in the symbols left by blood on the file bag, and I also found the witness, but he was worried that the murderer would not come over, so he only provided testimony."

"Didn't see the murderer clearly?" Ye Gengyi predicted in advance.

"Uh, right." Takagi nodded: "Witnesses saw only a man in a coat and stabbed the deceased in the abdomen..."

He said as he walked to the escalator and pointed at the blood on the ground:

"It's here that when the murderer and the deceased were fighting each other for the file bag, the power suddenly broke down... When the lights were on, the witnesses saw that the murderer took out a stack of documents from the file bag and then ran to it."

Before the power outage... Ye Geng walked to the escalator and looked down from a high place, and found that there was no blood in other places except the area where the dead body was located.

It should be on other steps.

Just as I was thinking, a big head suddenly emerged from my sight.

Conan looked smiling: "Brother Gengyi, you have noticed it too, right?"

Start the escalator and look for hidden clues?

Ye Gengyi said: "No."

Ah, this... I was planning to take advantage of the convenience of being a newbie and ask for a file bag from the police. Conan's smile stopped when he confirmed the guess.

"It seems that we still have to unravel the meaning of the message before death left by the dead with blood." Memu Shisan's eyes were deep.

He was so free... from the corner of his eyes he saw Ye Gengyi, who was chatting with Conan.

Just wanted to ask.

On the side, Suzuki Yuanko guessed: "Will that fork represent the '×' of multiplication, and the circle fork triangle refers to a certain mathematical formula?"

"But why write it as a circle-fork triangle?" Ran Maori was puzzled.

"Because I'm worried that the murderer would be discovered," Suzuki Yuanko explained confidently: "If this symbol is not used instead, if the prisoner sees it, the evidence will be destroyed."

If he had that opportunity, why didn't he snatch the entire file bag away...Judy Steeling secretly complained and quietly threw the topic back to Ye Gengyi:

"So, the murderer must be very proficient in mathematics?"

Proficient in mathematics?

For example, a guy who can calculate 58 people on the list in less than 2 seconds...

Memu Shisan first turned his head and looked at Ye Gengyi. Seeing that the other party had not finished talking, he had to turn around and ask Fan Jiu in the next life:

"Is there any employee in your company who is particularly good at math?"

"No," Fan Jiu shook his head in the next life, "due to business, our company recruits mainly liberal arts students..."

"By the way!" Maori Lan had a sudden inspiration: "Teacher Judy, Yuanzi... Do you mean this fork refers to 'x'? It's the cute mark the teacher said in English class..."

"Eh? Puff...hahaha..."

When Xiaolan said this, Suzuki Yuanko and Judy Starling looked at each other and suddenly burst into a crescendo.

"Impossible, absolutely impossible..."

"No!no! Maori classmate, you are definitely thinking too much..."

The two waved their hands repeatedly, denying her guess.

However, due to the excessive movement, Takagi Shiro from the side attracted him:

"What you said is, is it something that girls often write at the end of the letter..."

"Hey? Officer Takagi, do you know what 'x' means?" Ran Maori turned his head in surprise.

"Oh? This means you often receive that kind of letter?" Suzuki Yuanko leaned over and hit him with her elbow, teasing: "Who sent it to you? Officer Sato or other...."

"No," Takagi said ashamed: "It's all other people's pranks..."

"Takagi, what does that 'x' mean?" asked Meguri Thirteen.

"It's nothing. The 'x' we just said has nothing to do with the '○╳△' code this time..."

"Maybe it's not just the 'circle-fork triangle'..." Before Takagi Suk finished speaking, he was interrupted by Conan, who was unable to claim it and robbed it.

Everyone turned their heads and saw a detective pointing at the file bag that had just been snatched from the policeman and said, "Look at the left side of this circle, which is the most edge of the file bag, there are blood stains on it. Does this mean that the deceased wrote anything other than these three symbols?"

"You said this," Takagi Shiro explained: "We have noticed it before, but we have searched other places on the escalator and found no similar traces..."

"Then have you checked all the steps of the escalator?"

Conan continued:

"Don't forget, although this escalator is now stopped, it should be in the state of activation when the body is found. If the "death message" on the file bag is not complete, then the missing part must be on this step!"

"So that's it!" Takagi Suk suddenly realized, "I'll go and find the forensic staff to confirm!"

"But Conan, thanks to you being able to notice this detail, but it's better than some...huh?"

Memu Thirteen planned to take the opportunity to hit a technical association expert, and was about to get sarcastic, but when he turned his head, he found that the target was missing: "Where is brother Gengyi?"

"Strange, he just..."

Wait, this familiar sense of déjà vu... Conan widened his eyes. Could it be that he had found any clues he didn't know?!
