Back in the afternoon, Conan made an appointment for a toxicology test and took the bus back to the neighborhood where the Nagano House was located.

There are many suspicious points in this case, although none of them can directly prove that the characterization of this case is problematic, but it makes this case full of weirdness from beginning to end.

First of all, considering that Mr. Hiroshi Nagano was obviously walking towards Tang Sancai before he fell into a coma, there were only three reasons for his coma - long-range shooting, toxicology or pathology.

Long-range shooting can be left unconsidered, otherwise they should be able to find something strange in Mr. Hiroji Nagano.

If it's a pathological factor, then you don't have to worry too much about it.

But if it is a toxicological factor or a pathological factor caused by toxicology......

What cared most to Conan was what one of the three apprentices had said.

———— pull back in time

"Maybe the teacher went to see his favorite statue of Tang Sancai, right?" The last young man said. "The statue is really beautifully made, so I love it."

————

When Mr. Hiroshi Nagano was found, he was indeed in a coma looking at Tang Sancai, but this was too much of a coincidence.

Stepping off the bus at the station, Conan was about to find a way to blend into the neighborhood when he noticed something strange ahead of him.

A familiar Beetle was parked in a parking space on the side of the road.

"......," Conan sighed helplessly. Why are they back again......"

…………

Sitting on the bench, he stared coldly at Mitsuhiko Motota, who was scattered around the Nagano mansion, and Dr. Asasa who was following them, apparently on the lookout for their trouble.

"......" Ash Yuan sighed and shook his head helplessly.

Why would Dr. Asa allow them to come back and look into this thing, which doesn't count as a case by any means...... And why do you have to carry yourself over......

"Is it really you?" Conan came from a distance with a frown. "Isn't the Doctor supposed to take you back? How did you get here again? ”

"Didn't you come too?" Gray Plains asked. "What are you here for?"

"I always felt that something wasn't right, so I came back and took a look." Conan said with an expression that showed that he was clearly preoccupied now. "Did they find anything?"

"You also think there's something wrong?" Gray Plains frowned. "I thought it was just their imagination ......"

"If I remember correctly, the window of Mr. Hiroharu Nagano's room was not closed," Conan said after thinking for a moment. "I'll take a look."

That's when ......

"Don't go near that house!" I saw Dr. Asa shouting as he looked at Motota who came to the door of a nearby house. And he himself ran over as fast as he could.

"Huh?" Motota was taken aback by Dr. Asa and hurriedly took a few steps back. "Doctor, what exactly is methyl bromide fumigation?"

"Come back soon!" Dr. Asa had already taken three steps and two steps and ran in front of Yuantai, then directly picked up Yuantai and hurriedly moved away from the house with him.

"What's going on?" Conan was taken aback by Dr. Akasa's anxious appearance. "What the hell is going on?"

"That house just got fumigated with methyl bromide, right?" Gray Hara glanced at the white on the door of the house. "If you get too close to that house, you could be injured by a methyl bromide leak."

"Then please let you and the Doctor take care of them," Conan sighed. "I'll go to the Nagano Mansion first and see if there's anything strange."

"Wait a minute," Gray Hara said suddenly, looking at Conan, who was about to leave. "Let's see if there's any cat food, Mr. Nagano's cat has a big appetite, and the cat food in a small food bowl isn't enough for it to eat a second meal - which means that if you don't add food, the cat will starve tonight."

"Got it......" Conan was obviously a little disappointed after hearing that Gray Yuan Ai actually made such a request that had nothing to do with the case at such a time, and responded to Gray Yuan Ai's request with some weakness.

…………

After about 30 minutes, Conan walked out with an unwilling expression.

"Didn't get an answer?" Gray Yuan looked at Conan's expression and guessed a rough idea. "Is the cat fed?"

"I always feel like I'm missing something, and I'm not reconciled." Conan said helplessly. "As for the cat you mentioned, I didn't see the cat, but the cat's food bowl was full, and it didn't eat it."

"How is that possible?" Ashbara was stunned. "Impossible!"

"See for yourself, what did I lie to you!" Conan rolled his eyes.

"......" Instead of continuing with Conan, Ash Hara stood up and walked towards the Nagano Mansion by himself.

Three minutes later, Gray Yuan Wai walked back with a gloomy face.

"Did you find anything?" Conan saw that Gray Yuan's face was wrong, and immediately asked.

"Come and see." Gray Plains motioned for Conan to follow her.

Then they came to the base of the wall in Nagano's house, near the direction of the house where methyl bromide was fumigating.

"Are you showing me this new pipe?" At a glance, Conan spotted the misfit on the wall—a water pipe that was as clean as new lying on a somewhat old wall.

"There's a nameplate on it that says the date of production, and you can see what year it's a tube." Gray Yuan Wai smiled slightly, but did not refute Conan.

"Date of manufacture?" Conan leaned closer to the hose and set his eyes on the nameplate at a slightly higher position. "Wait a minute, Showa??? Showa 46 years??? ”

"yes," Gray Yuan nodded. "The water pipe in 1971 is still as clean as new 23 years later. Especially if you look closely enough, you can see that the room where the methyl bromide fumigation is taking place has an equally new water pipe on the wall. ”

"No......" Conan squinted his eyes as he looked at the house that was being fumigated. If that's the case, I think we'll need to talk to Officer Twilight...... I don't believe the owner of that house would be unaware that methyl bromide could leak here. Or rather......"

"He did it on purpose, didn't he?" Gray Yuan said lightly.

(The cat was in a state of recovering and was hiding under the bed, so neither Conan nor Gray Yuan saw it, and then the cat died after crawling back into the cupboard.) If it weren't for this, Gray Plains would have been able to save this cat. ）

———— back to the dividing line of reality

After the case was over, Kaede Hoshino walked with Chiba and the others on the way to the parking lot.

"I have a question," Chiba suddenly remembered something, and asked after Kaede Hoshino turned his head to look at him. "Why are you training your hands sensitive?"

"Of course←←, it's for practical purposes," Kaede Hoshino squinted.

“？” Thousand Feathers raised an eyebrow.

"Did you know~" Kaede Hoshino smiled and put his hand on Chiha's shoulder. "There are a lot of good things about a pair of skillful hands, such as—"

The delicate hand swam to Chiba's chest like a snake.

"You see, you're clearly in a state of flux right now, and if you're interrogated, you're sure everything will be taken out." Hoshino Kaede said with a smile. "A pair of dexterous hands can play with anyone's body and emotions when you need it, and the little guy who looks like a piece of wood won't understand, right?"

"Yes, yes, I don't understand!" Taking Hoshino Kaede's hand away from his body, Chiba puffed out. "I don't need to understand this weird stuff!"

In the midst of such conversations, the group drifted apart in the hospital corridors.
