Chiba, Gray Plains, and Conan walked side by side on the road

"You've decided to come with me, too?" Conan looked at Thousand Feathers and Gray Plains and said speechlessly.

"I was called," Qian Yu said lightly as he turned the Traceless Umbrella in his hand around. "He told me to go straight to the police station to find him."

"Looking for him at the police station?" Conan thought for a moment and immediately reacted. "It can't be Gregory, right?"

"yes," Chiba shrugged. "It was probably the new doctor who met Mr. Gregory and told him about our here."

"Even if he was called, it means that the police need his experience to determine what kind of pesticide it is."

Just as they walked around the corner to the street where the police station was located, they noticed that there seemed to be a bit of activity in front of the police station.

"What's the situation?" Chiba said as he let the auxiliary unit zoom in on the scene, while Conan pressed his glasses legs.

"Seems to be a journalist?" Chiba didn't confirm.

"It seems," Conan nodded. "The police seem to be opening a passage between journalists, presumably to let someone in."

"Anyway, it's definitely not for us......" Qianyu frowned. But there are so many reporters at the door, how do we get in? Do we want to go straight inside under the eyes of reporters and cameras? ”

"I don't want to, anyway," the corners of Conan's mouth twitched. "I'd rather climb over the fence and go into the police station."

"That's what I'm going to do......" Qianyu nodded. I don't want to be in front of the media at any time like this......"

Then, Qian Yu suddenly found that the gray plain mourning beside him didn't know where to go. Then, he felt something poke his back through his backpack. “！？”

"You're sluggish enough," Gregory slowly withdrew his cane behind him. Gray Plains was walking about a meter behind Gregory. "Even this girl has found out, but you still don't know it."

"My God......," Chiba breathed a sigh of relief when she realized it was Gregory. You are...... When did you start following us? ”

"I was behind you when you came out of the hotel," Gregory said lightly. "Okay, let's not talk about that, let's go directly to Shinshu University Hospital."

"Then why did you let us come to the police station?" Qian Yu was stunned.

"Because it was the Matsumoto Prefectural Police Station here that contacted the Metropolitan Police Department through my superiors, and it was the Metropolitan Police Department that contacted me." Grigory replied. "Do you think there's a better place to meet than at a police station? Not to mention that, the pesticides needed for such a high death toll are not like they can be raised by individual criminals, and it is dangerous to stay here for an extra second. ”

"As for you," Grigory said, looking at Conan. "If you want to go to the police station, walk back, there is a pharmacy about 50 meters from the corner, next to it is a street entrance, and you can walk inside for a while to the back door of the police station."

"......," Qian Yu was silent for half a second, and then showed an expression of sudden realization. No wonder I didn't see you before! (In fact, Gregory snuck out the back door of the police station to buy medicine, and then happened to see Thousand Feathers and them.) When I came out of the hotel, I followed the train that was purely full of mouths. ）

"Gone!" Gregory ignored Chiba and looked at Gray Plains. "Come on, too, the kid is here anyway."

———— Shinshu University Hospital

"Is this a map of where the patient is on?" Grigory looked at the map of the location. "Where's the symptom table?"

"Here you go." The new doctor said as he handed over a thick booklet.

"I'll take a look......" Grigory put the map on the table, then opened the thick booklet, comparing the symptoms and the location of the onset one by one. Have any health care workers experienced the same symptoms during their treatment? ”

"Yes." The new head nodded.

"I will take blood from critically ill patients and test the IMPA content in the serum, and I will get the results as soon as possible." Grigory ordered.

Gray Yuan Ai, who was sitting on the chair next to him, raised his eyebrows, and a look of surprise flashed in his eyes.

"Okay," the new doctor nodded. "I immediately submit your request to the testing department and perform a liquid chromatography examination as soon as possible, and report to you as soon as the results are between 2 and 135 micrograms per liter."

With that, the new doctor left.

"Hmm......" Grigory said in a subtle voice, looking at the new doctor who had gone away. What a knowledgeable colleague......"

"What is IMPA?" Qian Yu asked.

"......," Grigory glanced in the direction of Gray Plains' gaze. Can this young lady tell me about it? ”

(Normally, if Ashbara didn't know what IMPA was, she would probably look at Gregory rather than at Chiba - which means she knew exactly what IMPA was.) ）

"Isopropyl methylphosphonic acid, isopropyl methylphosphonic acid (author: please note that it is phosphonic acid and not phosphoric acid, one or two hydroxyl groups of phosphoric acid are replaced with alkyl groups or aromatic groups before phosphonic acid), hydrolysate of sarin gas. It begins to appear in serum about 4 hours after poisoning, and has a half-life of about 24 hours. ”

"That's right, you're very knowledgeable." Grigory nodded.

………… At the same time, outside the police station.

A police car stopped in front of the police station, which was surrounded by reporters and was left with only a passage about one meter wide that had been carved out by the police, and after several honking of the horn failed to disperse the reporters, the police car had to open the door on the spot. Two policemen escorted a man out and hurried through the passage.

"Yoshiyuki Kono!" A shout suddenly erupted from the crowd, and this sound instantly detonated everyone's emotions.

At this moment, the one-meter-wide passage was immediately slowly compressed by the crowd on both sides with a strong force. Seeing this, the two policemen who were escorting Yoshiyuki Kono immediately sped up.

"Bastard !!"

"Beast !!"

"Scum!!

"War criminals !!"

A variety of emotions such as sadness and anger are mixed in with various shouts.

"I'll fight with you!" With a terrible howl, a female reporter who looked to be about thirty years old suddenly lowered her body and slipped under the policeman's arm into the passageway, right behind Yoshiyuki Kono. Then, she used the microphone in her hand to strangle Yoshiyuki Kono's neck from behind, and then bit the back of Yoshiyuki's neck with her teeth.

……

"......" Conan leaned on the window on the second floor of the police station, looking at the situation outside, gritting his teeth slightly.
