Ke Xue: Shinichi and I are childhood friends.

As soon as school was over, You was blocked at the school gate by some brats from the Junior Detective League.

Hearing their purpose, You was taken aback: "Nature practice class?"

"Yes, yes," Ayumi nodded repeatedly, "Teacher Kobayashi wants to take us to the mountains of Gunma Prefecture to observe in advance whether the place is suitable for nature practice classes, but another teacher who is traveling with us suddenly caught a cold."

Youya understood: "So you came to me and wanted me to go with you?"

The three little brats nodded repeatedly.

Yuya was a little embarrassed: "But this kind of thing is the job of your school teachers, right? It's not my turn anyway."

Mitsuhiko said seriously, "But the other teachers are busy."

Ayumi raised her hands and said, "Besides, Mr. Kobayashi has already made an appointment with them, so there's no way to change it at will."

Yuan Tai nodded repeatedly: "That's right."

Yuu hesitated, looked at the three little brats and then at Conan, thinking about taking these four out or going to other counties. If there was no case, he would eat them upside down!

Finally, there were no cases these past two days and he had a few days of peace.

"Hey, Yuya brother, please, please!" Ayumi clasped her hands together, blinked her big eyes and begged with tears in her eyes.

Mitsuhiko and Genta also looked at him pitifully.

Yuya's expression froze. Mitsuhiko and Genta were fine, but who could resist being asked for help by such a cute and adorable loli like Ayumi?

He scratched his cheek, his eyes wandering elsewhere: "Well, this is not something I can't consider..."

Seeing that something was going to happen, Mitsuhiko quickly added, "Besides, when we asked Ms. Kobayashi if we could ask Brother Yuya to accompany us, she immediately agreed!"

"That's right!"

"Is that so?" Since Kobayashi Sumiko agreed, there was nothing for Yuya to refuse. He turned to look at Miyano Shiho and asked, "Mio, do you want to go with us?"

Miyano Shiho shook her head. "I'm not going," she whispered. "I still need to go back and refine the antidote. Back in Kyoto, the antidote Kudo took didn't last much longer than I expected. Maybe there's something wrong with the formula."

Pharmaceutical production requires constant experimentation and various clinical trials. Unfortunately, the antidote to APTX4869 cannot be tested casually, so Miyano Shiho must grasp the data of each medication.

Yuya glanced at Conan, and in the latter's puzzled look, he asked, "Do you need Conan's cooperation?"

Miyano Shiho shook her head: "No, I've already collected the data."

Yuya nodded to show that he understood, and then he said to the three little brats with his hands almost touching the ground, "Okay, I agree, but I have to tell you in advance that when you get to Gunma, you have to listen to Mr. Kobayashi and me. You are not allowed to run around casually. Got it?"

It would be fine if you caused a case in Mihua, but if you go to someone else's territory and cause trouble, that would be a bit inappropriate.

Someone obviously doesn't have much self-awareness. With him and Conan around, the three little brats' physical condition is not worth mentioning at all.

"Got it!" The three little kids nodded happily in agreement.

Just then, a familiar figure walked out of the school gate.

Wakasa Rumi saw several people standing at the door and couldn't help but ask in confusion: "What are you doing..."

···

Minokami Station, Gunma Prefecture

Yuya, the four little brats of the Junior Detective League, Kobayashi Sumiko, and Wakasa Rumi.

Here, the group met the elementary school teacher, Maika Zenda, who came to greet them.

"Welcome to Gunma. Does it feel very far from Kyoto?" Maika Zenda greeted with a smile.

Kobayashi Sumiko: "It's not too far. Thank you for picking us up."

Zenda Maika smiled and said, "No, no, our elementary school often takes students to that mountain to get close to nature. The children love it. It's a very suitable place for nature practice classes."

"Besides, this is my last job at school, so I'm really motivated."

Everyone was stunned: "The last one?"

Shantian Maika smiled and showed the ring on her left ring finger: "Because I'm getting married soon, I submitted my resignation to the school last week."

"Congratulations!"

Shantian Maika apologized with a smile, looked at the people in front of her, and asked with some confusion: "But, if I remember correctly, shouldn't there be six people coming this time? Who is this..."

She looked at Yuya, whose age clearly didn't fit that of an elementary school student or a teacher.

Kobayashi Sumiko quickly explained the reason for the incident: "So, Yuya-kun came here to accompany these children in place of the sick teacher."

Zenda Maika was stunned and looked at Wakasa Rumi: "Another teacher is sick? What about this one?"

Wakasa Rumi introduced herself, and Yuya added, "After all, I'm not as attentive as the teacher, and Ms. Kobayashi can't take care of so many children by herself. It just so happens that Ms. Wakasa is free, so I asked her to come along."

This time we are not here for tourism, but to dig wild vegetables in the mountains and get close to nature. The situation in the mountains is changeable, so it is better to bring an adult with you just in case.

"I see." Shantian Maika smiled, indicating that she understood. She turned around to look at her car, which was a 7-seater SUV. "Well, luckily the car I drove here was not small. There is no doubt that so many people can sit here."

Yuan Tai pointed at the car and asked, "Can we get in now?"

Shantian Maika nodded: "Okay, get in the car."

Yuantai couldn't wait to open the car door, muttering that he was the first one.

The car door opened, and on the seat lay a thick stack of folded cardboard boxes.

Shantian Maika quickly explained that she had put it in the car when she moved, but forgot to take it away.

So everyone got on the bus.

Kobayashi Sumiko sat in the passenger seat, Yuya and Wakasa Rumi sat in the middle row, and the four little brats leaned the cardboard box against the window and sat in the back.

Yuya looked around and saw that there were quite a few cardboard boxes in the car. They were standing up and blocking the rear window. Would it be dangerous to drive like this? He couldn't help but wonder.

However, the window on the left is empty, so you can see the scenery outside.

After making sure everyone was seated, Maika Zenda started the car and drove on the mountain road.

Kobayashi Sumiko and Zenda Maika were discussing teaching matters in the front row, while Yuya closed his eyes and dozed off. The little kids were looking at the scenery outside the window with great excitement.

Suddenly, I heard Yuantai shout excitedly: "Wow, there are so many high-end-looking houses over there!"

Mitsuhiko echoed, "It looks like a villa."

Unable to sleep because of the noise made by those little brats, Youya opened his eyes and glanced around casually. Not far from the roadside, there were villas standing.

Kobayashi Sumiko was very envious: "So there's a villa area here."

Shantian Maika was silent for a moment, then smiled bitterly and said, "Yes, but these things have nothing to do with ordinary people like us."

Yuya glanced at the back of Zenda Maika's head with a strange expression——

Teacher, you may not know that among the people on the bus, you teachers are probably the poorest.

There is no need to mention Conan, and Yuya's family background is not bad either.

Ayumi's family lives in the Tokyo Building, and the house is conservatively estimated to be worth hundreds of millions; Genta's family owns a national chain of fish stores; Mitsuhiko's parents are both teachers and their income is not low.

By comparison, Yuya suddenly discovered that the richest families here seemed to be Conan and Ayumi's?
