"Hmm......" Grigory sat in his armchair, looking at the test results table. 62 mcg per liter, it looks like I'm right. ”

"So what should we do?" The new doctor asked.

"You've done a good job before," Grigory said, glancing at the new one. "It is sufficient to continue treatment with a combination of pralidoxime and atropine. Come with me, little ghosts. ”

"Where else are you going?" Qian Yu tilted his head.

"I just got to the address of the suspect Yoshiyuki Kono from the police station, so we're going to go there to check if the suspect has any smuggled goods." Grigory got up from his armchair and walked to the door. "Without further ado, let's go."

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

"Judging by the list of pesticides you have provided to my ministry," said a man in a white lab coat looking at the police officer in front of him. "These organophosphate pesticides can be treated to produce this toxic effect."

"Are you sure?" The police confirmed. "If you are sure, we will immediately initiate arrest proceedings against the suspect."

"If you give us a living person to test on, I'll be more sure." The white coat said with white eyes. "All I can tell you right now is that these pesticides, when mixed in a certain percentage, produce the toxicological effects that you have reported."

"That's good." The policeman nodded, then turned to leave.

"...... you," the white coat asked suddenly. Where to go? ”

"Nothing." The policeman said lightly.

"Uh......" The white coat hesitated for a moment, but said nothing.

I don't know if it's an illusion, but when the police turned around just now, they seemed to show a terrible expression.

…………

Yoshiyuki Kono was lying on his bed in the restricted area of the temporary prison, staring blankly at the sky. His clothes were in tatters, and he was covered in bruises.

These injuries were all caused by the reporters in the process of being dragged and escorted to the police station by the police officers - crazy, restless, unscrupulous.

Just then, the sound of a metal door was heard outside - apparently a police officer had arrived. But Yoshiyuki Kono, who had been beaten to an exhaustion, no longer had the strength to sit up and pay attention to who was coming outside.

The policeman who had spoken to him before appeared outside the cell door like a ghost, and with a crisp sound, he opened the cell door and walked in.

"Yoshiyuki Kono," the policeman looked at Yoshiyuki Kono, who was lying on the bed and could only look at him with his eyes. "I didn't expect you to be beaten quite badly, huh?"

"They're just like ......," Yoshiyuki Kono said intermittently. Mad dogs...... What the hell is ...... What's wrong? ”

"Don't you know yourself?" The policeman walked up to Yoshiyuki Kono and said as he took something out of his pocket. "Well, do you know this person?" With that, he pulled out a large headsticker—on which was a little girl's innocent smile.

“？” Yoshiyuki Kono's expression did not change in the slightest. "I don't know, but I'm a lovely little girl."

"Her name is Keiko, and she is my favorite daughter." The policeman leaned down and said slowly. "Good athletic results and popular in school......"

At this point, the policeman smiled slightly, but quickly faded away.

"Actually, you should know her," the policeman knelt on the mattress beside Yoshiyuki Kono in a kneeling position. "Do you know why?"

“？” Yoshiyuki Kono's eyes showed a look of curiosity.

"Because ......" The policeman's voice suddenly deepened, and then his body suddenly exerted force and directly choked Kono Yoshiyuki's neck.

"Just last night, Keiko was killed by the poison gas you made!" The voice of the police has turned into a roar. "It's poison gas made from pesticides found in your house!"

His two hands were tightly wrapped around Kono's neck like iron tongs, and no matter how hard Kono struggled, he couldn't get rid of it.

"Thirty-nine lives!" The policeman's hands trembled from overexertion. "There are four old men among them! Seven kids! It's all done by you mad murderer! ”

"No......" Yoshiyuki Kono was speechless, and could only spit out individual bytes with such difficulty.

"The law can't sanction," Yoshiyuki Kono said hoarsely. "I'll sanction! Go to another world and reflect on your crimes! ”

At this moment, the policeman's expression suddenly stiffened, and then he unloaded the force of his hand and collapsed to the side.

Conan stood in the doorway and let out a sigh. "Caught up with ......"

"Little friend!" At this moment, the white coat also hurried here. "Why are you—"

His words stopped when he saw the police. "This ......"

"Let's isolate and protect this Mr. Yoshiyuki Kono first," Conan said. "Otherwise, this policeman would have been the first one, and someone would have attacked him in the same way."

Standing up, Conan's expression was solemn.

This is not a long-term solution...... The real thing to do is to find out if Yoshiyuki Kono is the murderer - Conan didn't think Yoshiyuki Kono was the murderer before coming here, because the poisoners were obviously a very tight gang and couldn't make the stupid mistake of leaving the raw materials at home.

But now it looks like Kono could have been the murderer – if he and another accomplice had synthesized poison gas directly at home and released it...... If it weren't for the fact that he was the first person to report his family's symptoms in detail, the police conducted a routine inspection of the first informant's home as customary, and it would have been impossible to imagine that such a kind-looking person would have hidden so many pesticides in his home.

"Please, call on the information we've gathered so far...... Conan muttered. Whatever the outcome, we have to come to a conclusion as soon as possible......"

…………

"This is our warrant," Gregory said, showing a warrant to the police officers who were guarding outside the building. "Let's get over."

"But it's just your warrant," the officer asked, after confirming it. "These two little kids?"

"Mind you, I have moderation," Gregory waved his warrant. "That includes who I bring in."

"Okay......" The policeman still looked like he couldn't mind.

"Don't worry," Gregory said leisurely. "I knew that Yoshiyuki Kono was unprotected when he was searched, so there must have been no poison gas in the house. The two children and I put on gas masks to give these pesticides a lot of face. ”

With that, Gregory walked into Kono's apartment with Chiba and Ashbara.
