Hearing what Tang Ze said, Gao Mu nodded, obviously agreeing with this statement.
But when he saw the three strange symbols "○×△" written in the deceased's blood, his face couldn't help but fall again. "What on earth is this death message?"
"Could that '×' refer to multiplication? And '○×△' refers to some mathematical formula?" Sonoko, who was standing by, speculated.
"But why is it '○×△'?" Xiaolan asked suspiciously, "Aren't numbers easier to understand?"
"That's pretty simple," Sonoko said, waving her hand. "They're doing this because they're afraid the criminals will find and destroy the information, so they use these strange symbols instead."
"Oh!!" Teacher Judy, who was standing nearby, excitedly said in a strange tone after hearing what Sonoko said, "So, the criminal is someone who is proficient in mathematics?"
Gao Mu looked at Lai Sheng suspiciously and asked, "Then may I ask if there is any employee in your company who is particularly proficient in mathematics?"
"No... Because of the field of work, our company mainly recruits talents with a liberal arts background..."
"kindness…"
"Could it be that this "○×△" refers to oden?" Yuanzi touched his chin, not knowing how his brain could think of oden.
"Hey... Sonoko, Teacher Judy, do you think this 'X' is referring to that thing..."
"Ah?" Hearing Xiaolan's words, Sonoko and the others couldn't help but look puzzled. "What did you say?"
"That's the cute symbol that Teacher Judy mentioned in English class..."
“Hahahahaha~~”
After hearing what Xiaolan said, Sonoko and Teacher Judy looked at each other and burst into laughter.
“No, no, no!!”
"That can't be it, it absolutely can't be that!!"
The two laughed and waved their hands to reject Xiaolan's guess.
"Ah, are you talking about what girls often write at the end of a letter..." Takagi, who was standing nearby, heard the conversation and couldn't help but ask with a smile.
“Oh! Yes~”
"Detective Takagi, do you know what "×" means?" Ran, who was standing by, looked at Takagi in surprise after hearing this.
"Hehehe, since you understand this, it means you often receive those kinds of letters, right?"
Sonoko, who was standing by, couldn't help but poke Takagi with a sly look on her face when she heard what he said, "I can't tell..."
"No, no!" Gao Mu quickly waved his hands and said, "I just help Detective Tang Ze and handle a lot of letters, so I naturally know..."
"Huh? Brother-in-law? That's normal..." Sonoko glanced at Xiaolan, then nodded as if it was a matter of course, "After all, he is my brother-in-law... That's normal..."
"So, Detective Tang Ze also knows the meaning of this "×"?" Upon hearing this, Xiaolan couldn't help but look at Tang Ze who was looking at the "death message" left by the deceased in deep thought.
"Well, I know that, but for some people, it might be a difficult puzzle to solve..."
Tang Ze looked down at Conan who was eavesdropping beside him, smiled teasingly, then looked at Gao Mu and said seriously: "Let's stop joking for now, I have discovered something..."
"Discover!?"
After hearing Tang Ze's words, several people stopped talking about the previous topic and hurried over, "What is it?"
"Perhaps this death message isn't just about '○×△'."
"Huh? What does that mean?" Sonoko asked curiously, "Could it be that this code is incomplete?"
"That's right, look? Is there a bloodstain on the left side of "○"? " Conan pointed to the edge of the file bag and reminded everyone.
"Ah, it's true..."
"Oh! If you look closely, there are indeed some vertical bloodstains..."
"But brother-in-law, there doesn't seem to be any bloodstains around here, right?" Yuanzi looked at the forensic personnel trying to search around and said, "I haven't seen anyone come to report, ah..."
"Based on the area we've checked so far, there's indeed no trace of blood, but we haven't checked that area yet."
Hearing this, Tang Ze pointed at the escalator and said, "Don't forget, although this escalator is stopped now, it was still running normally when the body was found.
So if there's a missing part of the "death message" on the file, it must be on the step of this elevator!"
"I see!" Gao Mu saw where Tang Ze was pointing and immediately realized, "I'll have someone check it out right away!"
"But brother-in-law, the escalator was running before you came, right? Could the words written in the deceased's blood have disappeared long ago?" Sonoko asked from the side.
"Don't worry about that. Just spray some luminol on the elevator pedals. Even if the blood has disappeared, it can still be found."
After explaining, Tang Ze continued, "Besides, the deceased had already been stabbed and was bleeding profusely. In that case, the elevator pedal would have been covered in blood. So later on, we just need to find the elevator pedal with the most blue fluorescence."
After explaining all this, Takagi hurriedly went to check the elevator pedals with the forensic department staff. At this time, Conan, who was next to Tang Ze, pulled the corner of Tang Ze's clothes, indicating that he should lean over and say something.
"What's wrong?" Tang Ze leaned over and asked, "Did you notice anything before?"
After all, Conan was present when the case happened, and with his insight he might be able to discover something.
But as a child, it was a bit too surprising to say these discoveries. To avoid suspicion, Conan usually told Tang Ze quietly. I thought this time would be the same, but I didn't expect...
"I want to ask you a question..." Conan covered his mouth and asked in a low voice: "What does the "X" that Sonoko and the others mentioned before mean?"
“…”
Hearing Conan's question, Tang Ze looked at Conan with a playful look on his face, rubbed his head and said: "It's okay for a child not to know about this kind of thing~"
What a joke! Tang Ze is still waiting to see the news later. How could Conan know about this first?
As for what Conan's expression will be like at that time, I am looking forward to it~
"If you know, just tell me!" Conan angrily slapped his hand off his head, "I'm not a real elementary school student!!"
Faced with Tang Ze's evasion, Conan wanted to continue asking, but Chiba hurried over with a pile of clothes in his hand, interrupting their conversation.
Seeing this, Conan could only glare at Tang Ze fiercely, and then began to listen attentively to what Chiba and others had discovered after the search.
