Saturday, October 1, 1994, was a great day.

Because the Junior Detective Corps came to a place where matsutake mushrooms (pine mushrooms) can be collected today.

"Adults can collect three each, and children can collect two each," the staff enthusiastically introduced. "When you're done, you can give it to us, and the inn will prepare the food for you. But I would like to last warn you not to cross the barbed wire fence – beyond one barbed wire is the buffer zone, and beyond the two barbed wire fences is the bear zone. ”

"Don't worry, I'll take care of the children, and you've told them many times!" Dr. Asasa smiled and reassured the staff.

"Why is it limited, is this thing scarce?" At this moment, Motota seemed to be a little dissatisfied with the staff's quota. "Even though the accommodation price is so expensive, they are so stingy with our picking...... How can we get the cost back now! ”

"Not only is it scarce, but the growing conditions for matsutake mushrooms are quite harsh." After glancing at Motota, Qian Yu replied in a dissatisfied voice. "I'll just put it this way, the 120-gram fresh matsutake mushroom that can be bought on the shelves of imported ingredients usually has four matsutake mushrooms, and then the price is a full 10,000 yen. Considering how expensive this thing is, how can the store let you pick it? Although the local matsutake mushroom is not so expensive, people also need to leave profit margins! ”

(Japan is a major producer of matsutake mushrooms, but it's also a major consumer, so it imports thousands of tons each year — quite a lot in terms of price.) As for the content of the original book...... Motota seems to be more interested in the price of this than Ayumi, which is obviously not quite right, so I fixed it by the way. ）

"Is it so expensive?" Gray Plains Wai next to him was taken aback. "Wasn't that yesterday ......?"

"When did the food in our family get cheaper→→ Qian Yu glanced at Gray Yuan. "And now is not the time for large-scale harvesting of matsutake mushrooms in China, so the prices of those matsutake mushrooms picked earlier in the Far East will be particularly expensive - especially now that you are often away from home for dinner, so when I go home to eat, I will increase my budget, so naturally I will buy matsutake mushrooms."

"Gray Yuan-san, you...... Skipping dinner? Mitsuhiko was surprised when he heard Chiba's slightly complaining words.

"I ...... at night It's a bit of a thing, so I didn't eat it at home. Gray Plains shook his head faintly.

Gray Hara hadn't had much dinner at home since the last time she went to see Chiba and Ayumi doing the backtracking work, and every time she went to the lab or something like the lab as soon as school was out of school - her own explanation was that the antidote was about to be developed, so she had to keep an eye on it to make sure there were no problems.

That's true, but ......

Just when Qianyu was a little troubled, Conan gently pulled Qianyu and took him aside.

"Did you have any conflict with Gray Plains?" Conan asked. "These days, whether it's at school or on the way here...... When have you ever seen you ride in a car with her, and when you're around her, she reads a book from time to time and chats with Ayumi from time to time? ”

That said, it does seem a bit ...... She had a rare book with her when she came, and she did seldom talk to herself.

Qianyu's gaze darkened slightly.

"I don't know, at least I haven't found the reason......" he replied with a glance away from Gray Plains, who was facing away from them.

While they were talking, Dr. Asasa turned his head and looked at everyone as he watched the staff leave.

"Okay, time is limited, so let's go look for matsutake mushrooms first." Dr. Asasa reminded. "We have a lot of time, but there are already a lot of people who have come here to pick them before, so the remaining stock of matsutake mushrooms may not be very large, and they are often only left in difficult places."

"But can you really find matsutake mushrooms this time?" Gray Yuan Wai suddenly asked Qian Yu, who was a little stunned. "Although it was proposed by you and Edogawa together, I have investigated a little bit before and have not heard any recommendations for this land at all."

"Because the matsutake mushrooms in the popular places are not as good as the quality here, or the price is worse, if the purpose is to taste matsutake mushrooms, this is indeed the best place." Conan replied. "As for the reason......

"Those more famous matsutake free picking spots are too early to become famous." After seeing Conan's turned eyes, Qian Yu took over the topic. "I'll give you an example, our domestic matsutake mushroom and the northeastern region of the Far East belong to the same [Japanese matsutake mushroom], but our domestic matsutake mushroom ...... A bit of premature aging. ”

"What does that mean?" Dr. Asasa didn't do much homework on the minutiae despite bringing them in.

"The growing conditions of matsutake mushrooms are still quite harsh – the pine is required to occupy an absolute advantage in the forest area, that is, about two-thirds. In Japan, matsutake mushrooms can be produced at the foot of red pines around the age of 20, and the best time is around 35 years old, while the red pine at the age of 70 basically no longer produces matsutake mushrooms. However, the same matsutake mushroom in the Northeast region of the Far East is about 20 years later than our native ones in terms of age. That's why I describe it as 'Progeria'. And those famous matsutake production points have basically been used as matsutake production sites during the Shenwu boom, and the amount of matsutake that can still be left there is ......."

"And it's younger here, isn't it?" Dr. Asa immediately understood what Chiba meant. "I see, and considering that this is not a particularly famous picking location, it is true that this is a place with a relatively high yield and a relatively low harvest."

"It's a pity that Ayumi didn't come along, as if she was going to do something or something?" Mitsuhiko muttered.

"Things?" Conan was slightly stunned, and then he also reflected that Ayumi seemed to be very busy with her clothes recently. "yes, isn't there a lot of things going on lately in Ayumi?"

"Well, there's something going on at home, maybe ...... Can it be done in about half a month? Qianyu replied casually. Until then, I'm probably going to focus on these things. ”

On October 15th, there will be a large-scale charity concert held simultaneously around the world, and Ayumi will participate in it - maybe it will be recorded in the memory of many people as a part of history.

If you calculate it this way, Ayumi should be considered to have gotten a ...... What about a chance to reach the sky in one step? If you behave properly on stage, you will really become famous in one fell swoop.

However, even if she can perform here successfully, it is still unknown whether the real purpose of her doing all this can be achieved - fame is not her goal, just her means.

Thinking like this, Qian Yu pursed his lips, but he didn't notice that Gray Yuan Ai was looking at his side face, thinking about something.
