"Ah, Chiba is indeed still there." A different voice came from the door again, and when Qian Yu looked back again, he found that a thin police officer outside the door was whispering something from the phone installed at the door of the file room. If Chiba is not mistaken, he should be a subordinate of the Twilight Police Department, whose name is Wataru Takagi.

"Huh?" Chiba closed the file and walked over to the thin officer. "You're Officer Takagi, aren't you?"

"Huh? Ah no, it's okay, it's just that Chiba came to me, please wait," Takagi said into the phone, and then put the phone down. "Chiba, what's the matter?"

"Who's on the other end of the line?" Qian Yu said lightly.

"Huh? Oh, it's Conan, are you going to talk to him? ”

"Okay," Chiba reached out and took the phone. "Conan?"

"Qianyu, are you still reading the dossier?" Conan's voice came from the phone.

"It's still there, what's wrong?"

"Did you find anything?"

"After connecting the disappearance sites, ransom payment locations and dumping sites of the first three kidnapping cases, a XI figure was formed, and the autopsy report of the third person came out, and after reading the report, I suspected that the murderer took the girl to the dumping site to dismember the body on the spot."

“XI？” Conan's focus did not surprise Chiba.

"yes, XI, I don't feel like it's romanized, and I can't find any English words that make sense."

"What about the Greek letters?" Conan asked. "There's a xi in the Greek alphabet." (The fourteenth letter of the Greek language, Ξ (uppercase) and ξ (lowercase) is pronounced as xxi (xi))

"Greek letters? If the kidnapper's purpose is to provoke, it will be very ineffective in Greek, because it is too biased and too tricky. And too long a word will indeed allow the police to find patterns and reduce security. ”

"Oh yes, if you put the location of Ayumi's abduction on the map, would you find anything?" Conan suddenly thought of something and commanded. "Then put it in your notebook and show it to me when you have time."

"Where are you?" Chiba asked.

"I'm at Ayumi's house."

"Ayumiya?" Chiba was surprised. "Why are you there?"

"Pacify Ayumi's parents," Conan said quickly. "They're crying to tears."

"I see, we still have plenty of time for the time being, I'll go to you after I zoom out the map. Do you have anything else to talk to Officer Takagi? ”

"It's gone, hang up."

Chiha hung up the phone and walked quickly back to the map, marking the location of Ayumi's disappearance on the map.

The location of Ayumi's disappearance is in a straight line with the disappearance of the other three, and it seems that the kidnappers intend to write the third letter in Ayumi. The second, third, and fourth kidnapping locations are equidistant, so if this letter is written by Ayumi alone, it is one of the DIJLVs, and if it is written by Ayumi and the subsequent victims, it is one of the BEFHKMNPRTUWXYZ.

Qianyu opened the dictionary and looked it up one by one

XID, can't pick up the word

XII, Roman numeral 12

XIJ, can't pick up the word

XIL, can't pick up the word

XIB, isoborneol xylenol, Xibe

XIE, can't pick up the word

XIF, can't pick up the word

XIH, can't pick up the word

XIK, can't pick up the word

XIM, X-ray intensity meter, Rosewood spp

XIN, I can't pick up the word

XIP, executed in place, sword-like

XIR, can't pick up the word

XIT, plus input terminal

XIU, CAN'T PICK UP THE WORD

XIW, can't pick up the word

XIX, Roman numeral 19, Tangut script

XIY, can't pick up the word

XIZ, can't pick up the word

There are four most likely words in this – Roman numeral 12, Roman numeral 19, executed on the spot, sword-like. These four words represent XII, XIX and XIP, no matter which way they are written, the end of Ayumi's pen remains the same, that is, from the place where Ayumi was kidnapped to the place where the first three deceased were dumped, the vertical line of the straight line, which is where Ayumi will be killed!

Qian Yu glanced at the clock and saw that it was 9:50, so he marked the location on the map, wrote a "key-place", and then handed the map to the administrator of the file room. "I'll hand it over to him when the Dusk Police Department comes."

A small figure in black clothes left the file room.

。。。

Outside Yoshida's house.

"Knock knock—" Thousand Feathers knocked on the door, and a few seconds later, the door opened.

"Chiba, you're finally here," Conan said with a look of lovelessness. "I'm going to go crazy if you don't come again."

"What's wrong?" Qian Yu walked in, frowning as he heard a cry coming from through the door. "Them?"

"Just now, the kidnappers called and informed Ayumi's parents that Ayumi had been kidnapped, and now they are crying with Motota and them."

"Take me to meet them, and I'll report on the information I've gotten that night." The corners of Qianyu's mouth twitched and said.

"What intelligence? Don't make them break down. Conan asked, glancing at a nearby door.

"First, their daughter was absolutely safe for two days. Second, their daughter is absolutely safe until she is taken to a certain location. Thirdly, I think I've found this so-called 'somewhere.' ’”

"What?" Conan was overjoyed. "Tell me more about it first!"

"I just thought I had found this location," Chiba shook her head. Whether it's correct or not won't be until a day and a half later, when the kidnappers will tell Ayumi's parents where to pay the ransom. Only when the delivery location did not surprise me could I confirm that my inference was correct. ”

"That's fine, just go in and talk to them, and pay attention to appeasing Ayumi's parents." Conan pointed to the door he had glanced at earlier. "It's all in there."

Chiba walked over and knocked on the door.

"Conan?" Mitsuhiko's voice was heard from inside the door, and the door was opened. "Huh? A thousand feathers? ”

"Well, I'm here." Qian Yu said and walked into the house.

The room is decorated in pink, with Kamen Superman wallpapers or stickers everywhere, and it's self-evident who the owner is. A man and a woman were sitting on a pink bed sobbing, while Motota was sitting on the ground without saying a word, her head bowed.

"You are?" The woman asked with a sob, opening her eyes that were already red from crying.

"I'm Chiba Tachibana, a classmate of Ayumi. I have just returned from going through the files of the Metropolitan Police Department, and I would like to inform you of some information. ”

"Dossier? You... The woman was interrupted by the man in the middle of her sentence. You let him speak. ”

"First of all, based on the pattern of the first three victims, we were able to guarantee that Ayumi had at least 40 hours of absolute safety and about 10 hours of theoretical safety time."

"Theoretical security?" The man asked. "What does that mean?"

"Based on the previous model, Ayumi is safe, but we can't prove it." Chiba replied. "In the previous three cases, the hostages were presumed to have been killed between 5 a.m. and 6 a.m. on the fourth day after their abduction. Do you understand now? ”

——————Hearing this, the woman began to cry again, while the man hugged the woman and whispered to Qianyu to continue.

"Again, based on the other side's pattern, I speculate that the kidnappers will only kill the kidnapped girl after taking her to the place where her body is dumped." Hearing the sobbing sound that became heavier again, Qian Yu slowed down her tone and spoke as softly as she could. "Luckily, I think I've figured out the kidnappers' pattern of choosing a place to dump the body, so we can ask the police to arm around the dumping site and rescue Ayumi."

"Is the success rate high?" The man continued.

"I don't know, if I use a sniper as I envisioned, it should be high, after all, depending on the situation at the scene, it is impossible for the kidnapper's weapon to be in his hand." (There aren't many things that shred up corpses without making too much noise, but most of them were sharp knives with a base to cushion like a guillotine.) The guillotine system that can cut off a girl's limbs is basically not something that can be held with one hand when the unconscious girl is going to be carried in the other. ）

"Understood." The man patted the woman on the back. "Do you hear that? Ayumi is still very safe, take it easy, otherwise you will be so tired that you won't even have the strength to make breakfast for Ayumi who returned safely, good ~ good ~"

Under the man's soothing words, the woman gradually stopped sobbing.

"Alright," Chiba said with a smile. "Let's calm down, do our part, and don't drop the chain when we need our strength."

Seeing that the woman's mood gradually stabilized, Qian Yu walked to the window next to her, and her expression became cold.

Qian Yu was betting on the kidnapper's kidnapping idea, but he couldn't afford to gamble at all. As long as there is a slight slip of the eye, then a fresh life that has just appeared in Qianyu's new life will be sung in the most cruel way in front of Qianyu, and it will leave in the most creepy way.

However, Qian Yu can only gamble with the kidnappers, because not gambling will only be worse.

Come on, Mr. kidnapper, let's have a showdown!
