About fifteen minutes later, Rice Flower Central Hospital.

"He? Being completely healthy proves that we do have the ability to turn a genetically appropriate adult into a child, and that the child's tissue health will regress to a young age at the same time. Gregory took the study and said to Thousand Feathers and Gray Plains. But...... I think his new classmates and he will probably be in a situation where they will be tired of each other. ”

"Let the killer go to elementary school," Gray Yuanai's expression was quite relaxed at this time. "Should we find a way to send him to Texas for elementary school? He's probably going to be at home over there. ”

"Straight down," Gregory continued, smiling and shaking his head. "If the next phase of clinical trials is successful, I think we can put those drugs into practice – we got some ...... African logs can provide us with enough material for human experiments. ”

At that moment, the electronic display in Gregory's office lit up, causing all three people present to look at it at the same time.

【Metropolitan Police Department First Aid】

"Why did the Metropolitan Police Department give me the living person, aren't you afraid that I will cut it open first when I see the living person?" Grigory frowned slightly. "You two...... Come with me, too. ”

"Huh?" Gray Yuan said in surprise. "Usually you're not just ......"

"Being a doctor is a promising career, especially since I know that you two have done this before, at least not worse than these rookies here, right?" Grigory sat up, stood up with the help of his cane, and walked in the direction of the door. "Hurry up, hurry up, get moving!"

……

At the same time, the auditorium.

"At present, it can be preliminarily concluded that it is poisoning, and the carrier should be this bottle of drink that has been drunk for more than half of it," the forensic officer reported to Kiyocho Matsumoto at the scene, who was supposed to be in charge of the crime investigation at the scene by Officer Shiratori, who was supposed to take the place of Officer Twilight, who went home to attend to his wife's funeral, but their superiors were here, so naturally they entrusted these responsibilities to the relevant person such as their boss and the victim's father. "As for the specific poisons, we have currently determined that these tablets and capsules with different degrees of dissolution are the first thing you pour out of the tea."

"Pills and capsules," Matsumoto Kiyoshi frowned. "You mean, the prisoner used multiple drugs at the same time to poison at the same time? Seems redundant, right? ”

"Yes, it does seem redundant, but ......" the forensic staff was equally hesitant. But it is true that there are multiple drugs in it at the same time. ”

"That," said Moriran, who had been called by someone who had been in close contact with Sayuri Matsumoto before she was poisoned. "The teacher added a lot of things to the jar at that time, saying that it was vitamin C for flavoring."

"Vitamins?" Matsumoto Kiyocho was surprised by this. "Sayuri, she shouldn't have taken these medicines normally, but the results of her last physical examination were very healthy!"

"The degree of dissolution varies," Conan asked suddenly. "Excuse me, how different are these capsules?"

"Very big," was the forensic officer's reply. "One of the capsules had about 70 percent left, while the others were more than 70 percent dissolved when they were poured out."

"Considering the quantity, can we assume that these capsules were not delivered by the same person?" Conan asked. "After all, most of the dissolved capsules are a lot of them, and compared to the possibility that other people put them in, I prefer that this batch of fast-dissolving capsules was finally taken by Matsumoto-sensei... I mean, Sister Sayuri put it in herself. ”

"But the one in front may not be," Kiyoshi Matsumoto heard the meaning of Conan's words. "So the one in front of you is probably the murderer—"

"Actually, it's possible that one of the capsules that was thrown in together is different," the forensic staff muttered as they looked at the capsules side by side. "For example, there is a poison capsule or something."

At this moment, Matsumoto Kiyonaga's phone rang, and it was a call from Gregory, who had taken over Sayuri Matsumoto's treatment.

Sayuri Matsumoto woke up, after not doing anything other than oxygen.

……

"I had just taken a sip and all of a sudden I felt weird in my throat...... My tongue swelled, and I couldn't breathe in air," she told Gregory's assistant. "And then I passed out."

"Your tongue swells up and you can't breathe in air?" Fujiwara stopped his pen and looked at Sayuri Matsumoto with a somewhat odd look. "You...... Are you sure you didn't swallow your tongue? ”

"Tongue swallowing?" Sayuri didn't understand at first. At this moment, Gregory walked in with Thousand Feathers and Gray Plains.

"I can't breathe after my tongue is swollen, I may have swallowed my tongue, but I haven't checked ......"

"He says he can't breathe?" Grigory frowned, looking at Fujiwara like this. "The next time I suspect a sober person swallowing his tongue, I will go to the water department for examination...... Forget it, I'll go to the anorectal department as a handyman. ”

"Anyway......" Fujiwara said, realizing his omission. When I checked it just now, there was nothing abnormal in my throat. ”

"Can you describe how you can't breathe air?" Grigory said as he glanced at Sayuri Matsumoto's slightly stained dress. "Where's the blockage?"

"Ass......" Sayuri Matsumoto hesitated. I just can't suck it in, but I'm not sure what went wrong, I just feel bad in my throat. ”

"That is, there is an intermittent problem somewhere in the respiratory system," Grigory pouted. "Take some blood, do a CT of his chest, and take him to the plethysmography room to see how his lungs are moving — remember to call the water department back."

……

In the body drawing room, there are only Hotaru, Ashbara Ai and Sayuri Matsumoto, whose upper body is only left with a bra.

"Don't worry, this box is designed to test your ability to breathe, because it's a confined space, so you can accurately determine the strength of your lungs." Hotaru said as she attached a sensor to the edge of Sayuri Matsumoto's bra — which is why the two boys needed to avoid it.

"With this respirator, we need to get you to breathe in from the outside through this to complete this test." Aiya is handing the respirator to Sayuri - unlike Hotaru, she can't do her job on her own because she isn't tall enough. But at this moment, Hotaru had already attached the sensor and took the respirator from Ashbara's hand.

"I'll do it," said Hotaru, who expertly put a respirator on Sayuri Matsumoto. "By the way, why are you and that kid here too?"

"What about you, who was pulled by Gregory?" Gray Yuan asked rhetorically.

"Make up the numbers?" Mizuko Hotaru looked surprised, but continued after closing the body drawing cabin. "There are a lot of people who have submitted their resumes, and most of them have been brushed off...... In the end, it seems that less than 10 of them have qualified. ”

"Is your resume flashy?" Gray Plains raised his eyebrows. "Gorgeous enough to beat so many people?"

"Seriously, my resume was almost blank because I was applying for another internship...... "Hotaru spread her hands." I actually asked why I was chosen instead of those who were more capable, and he answered......"
