Hearing Tang Ze's words, Takagi couldn't help but nodded, obviously agreeing with this statement.

But when he saw the three strange symbols of "○×△" written by the deceased in blood, his face couldn't help but cross again, "What the hell is this death message!" ”

Could that "×" refer to multiplication? "○×△" refers to some kind of mathematical formula. The garden on the side speculated when he heard this.

"But why '○×△'?" Hearing this, Xiaolan was suspicious: "Aren't numbers easier to understand?" ”

"It's pretty simple." Yuan Zi waved his hand and said, "Naturally, I am afraid that the prisoners will find out and destroy the information, so I will replace it with this strange symbol." ”

“OH！！” Teacher Judy on the side also said in a strange tone when she heard Yuanzi's words: "So, is the prisoner a person who is proficient in mathematics?" ”

Hearing this, Takagi looked at the next life with suspicion and said, "So may I ask if there are any employees in your company who are particularly proficient in mathematics?" ”

"No... Because of the field of work in our company, the new recruits are mainly liberal arts talents..."

"Well..."

"Could it be that this "○×△" refers to oden?" Sonoko touched his chin, and his thoughts, which he didn't know how his brain diverged, actually thought of oden.

"Hey... Garden, Teacher Judy, do you mean that this "×" refers to that thing..."

"Huh?" Hearing Xiaolan's words, the two of them couldn't help but wonder with their expressions, "What did you say?" ”

"That's it, that cute mark that Teacher Judy said when I was in English class before..."

"Hahaha~~"

Hearing Xiaolan's words, Yuan Zi and Teacher Judy glanced at each other and laughed.

“ No， no， no！！”

"It can't be that, it can't be!!"

The two laughed and waved their hands to reject Xiaolan's speculation.

"Ah, are you talking about something that girls often write at the end when they write letters?" Takagi on the side couldn't help but ask with a smile when he heard the conversation between several people.

“OH！ Yes~”

"Takagi Criminal, do you know what '×' means?" Xiaolan on the side looked at Takagi in surprise when she heard it.

"Hey, hey, since you understand this, it means that you often receive that kind of letter?"

The garden on the side heard Takagi's words and couldn't help but pound the other party with a narrow face, "I can't see it..."

"No, no!!" Hearing this, Takagi hurriedly waved his hand and said, "It's just to help Tang Ze criminalize and deal with a lot of letters, so naturally I know..."

"Roar? Brother-in-law? It's normal..."Yuan Zi glanced at Xiaolan, and immediately looked like a matter of course, and nodded, "After all, it's my brother-in-law... It's also normal..."

"So, Tang Ze also knows the meaning of this "×"?" Xiao Lan couldn't help but look at the words and looked to Tang Ze, who was looking at the "death message" left by the deceased and pondering.

"Well, I still know this, but for some people, maybe it's a puzzle that is not easy to solve..."

Tang Ze looked down at Conan, who was eavesdropping on with his ears pricked up beside him, smiled teasingly, and then looked at Takagi Masasei and said, "Let's go here first to talk about jokes, I have some discoveries..."

"Discovery!?"

Hearing Tang Ze's words, several people stopped talking about the previous topic, and hurriedly ran over, "What is it?" ”

"Maybe this death message doesn't just have a '○×△'."

"Huh? What do you mean? The garden asked strangely, "Is this code incomplete?" ”

"Yes, you see?" Is there a blood stain on the left side of the ○?" Conan pointed to the very edge of the file bag and reminded the crowd.

"Ah, it's true..."

“oh！ If you look closely, it does have a little vertical bloodstain..."

"But brother-in-law, there doesn't seem to be any blood around you, right?" The original paper looked at the forensic personnel who tried to search around and said, "I didn't see anyone come to report, ah..."

"Judging from the place where it is inspected now, there is indeed no similar bloodstain, but there is no inspection there."

Hearing this, Tang Ze pointed to the escalator and said, "Don't forget, although this escalator is stopped now, when the body was found, the elevator was still operating normally."

So if the "death message" on the file bag is missing a part, then it must be on the pedal of this elevator! ”

"I see!" When Takagi saw the place Tang Ze was pointing to, he immediately came to his senses, "I'll have someone check it right away!" ”

"But brother-in-law, the escalator was running until you came, right? Could the words written in the blood of the deceased be long gone? Yuan asked from the side.

"Don't worry about that, just spray some luminol reagent on the elevator pedal, and even if the blood is gone, you can find it."

After explaining, Tang Ze continued to add: "And the situation at that time The deceased had already been stabbed and bleeding nonstop, in that case, the elevator pedal must be stained with blood, so you only need to find it later, and the elevator pedal with the most blue fluorescence is enough." ”

After explaining all this, Takagi hurriedly went to check the pedals of the elevator with the personnel of the identification class, and Conan next to Tang Ze pulled the corner of Tang Ze's clothes at this time, signaling him to lean over and have something to say.

"What's wrong??" Tang Ze leaned over and asked, "Did you notice anything else before?" ”

After all, Conan was present at the time of the crime, and with his insight, he might be able to discover something.

But as a child, it is a little too surprising to say these discoveries, in order to avoid suspicion, Conan usually tells Tang Ze quietly, I originally thought it would be the same this time, but I didn't expect it...

"I wanted to ask you a question..."Conan covered his mouth and asked in a low voice, "What does the "×" they said in the garden mean before?" ”

“......”

Hearing Conan's question, Tang Ze looked at Conan with a playful look and rubbed the dog's head and said, "This kind of thing, children don't know if they don't know~"

What are you kidding, Tang Ze is still waiting to eat melons later, how can he let Conan know about it first.

As for what Conan's expression will be like at that time, Brother Tang is looking forward to it~

"If you know, tell me!" Conan slapped the hand on his head hatefully, "I'm not really a schoolboy!" ”

In the face of Tang Ze's prevarication, Conan wanted to continue to ask, but Chiba on the side hurriedly ran over with a pile of clothes in his hand, interrupting the conversation between the two.

Seeing this, Conan could only glare at Tang Ze fiercely, and immediately began to listen intently to the findings of Chiba and the others after searching.
