After walking a distance, an area covered with various stones appeared in front of everyone.

"I think maybe the mine is around here... Tadao muttered.

"Yes," Conan agreed, taking a closer look at the stone. "Thick artificial traces...

First of all, many of the stones have some abrupt smash marks on them, which are obviously caused by professional tools such as shovels. Moreover, many stones are stacked on top of each other to form a stone wall.

"What's that?" Motota suddenly pointed to a strangely shaped stone not far away. "It looks like a big plate, is it a pot from the Warring States period?"

"Pot?" Conan was slightly stunned, and then came to "the pot" with everyone.

The whole "pot" is round, about 50 centimeters in diameter and about 15 centimeters thick, which really looks like a pot in the eyes of children like Yuantai. But this thing is actually ...

"This is a stone mortar... Conan said with a smile. "It's a tool used to crush ore in ancient times, and it's a common thing in the mines!"

"Crushing ore?" Yuan was at a loss.

"The ore needs to be crushed into powder to extract the gold from the gold ore... Conan shrugged.

"Gold?" Mitsuhiko said excitedly. "Does that mean there may be gold on this mortar?"

"Gold ???" When Motota heard this word, he immediately became excited, and even ran to the side of the stone mortar, trying to lift the stone mortar up.

"Is this definitely a gold mine?" Ayumi wondered. "Won't it be another mine?"

"For the record, there are only gold mines here," Conan replied, shaking his head. Then, he saw Yuan Tai's ridiculous behavior and couldn't help but say with a smile. "Yuantai, you think too much, even after crushing, gold ore is still not gold dust! Gold can only be obtained by sorting it by running water, and then by burning it with fire to remove impurities and refining it. What is on the mortar is just ore powder. ”

"Okay... Yuan Tai said, the frustration on his face palpable.

"Alright," Tadao clapped his hands and asked everyone to look at him. "Let's keep looking for the mine."

。。。

When they came to a very flat cubic pit, everyone saw what was in the pit - a mine.

"This should be it..." Looking at the mine in front of him, Conan could hardly hide his excitement. "Step!"

"It should be... Tadao nodded as he looked at the looming wooden structure inside the cave that was used to reinforce the cave. "Otherwise, the cave would never have been fortified in such a rigorous way."

"At the same time, we can know that those two guys probably got in from here." Conan motioned for everyone to look at their feet.

Several vines stretched out from their feet and hung down from the pit. Notably, there is a vine with a broken end that is lying next to several other vines, and the port of this vine is very new.

"So, we're going to confront them head-on," Conan said solemnly, checking his equipment. "Cheer up, everyone!"

"What do you mean on the prompt?" Tadao looked at Conan and asked. "From 'The Hidden Afternoon Horse and the Monkey' to 'The Hidden Road Calls Me'."

"I don't know," Conan shook his head. "I really don't know, give me a moment to think about it."

The hidden afternoon horse and other Shen monkeys are infested

The road suddenly detoured, and the snake and the sheep looked at the dragon and were confused

Follow the side of the Beidou, and the hidden path calls to me

The whole paragraph is quite confusing, and I can't find any valuable meaning... Even in terms of the grammar of Takeda Shingen's time, this is quite a strange statement...

Then, the meaning of the existence of this passage should not lie in the literal meaning of this passage, but in the element that every word in this passage has...

At the same time, there is a structural difference between the third line and the first two lines, because the third sentence does not refer to the zodiac like the previous sentence.

Follow the side of the Beidou, the hidden road calls to me?

Follow the direction of Beidou? The Big Dipper is in the north, but if Conan remembers correctly, the hole in front of him is to enter the mine from north to south, and following the direction of the Big Dipper will only come out!

The square that follows the Beidou? But the square of the Beidou will go in different directions according to different seasons.,It's not okay.。。。

Follow the square of Beidou? The Big Dipper is seven stars, how square - wait, the Big Dipper!??

Seven... Seven squared ... Forty-nine...

Conan suddenly turns to Tadao. "Brother Tadao, lend me your notebook again, and then please give me another pen!"

When Conan got his notebook and pen, he immediately counted it in the notebook.

Everyone waited for Conan to calculate - although it was possible that Gray Yuan Ai was caught by the bad guys, and although arriving at the place where the treasure was located a second late would make Gray Yuan Ai a little dangerous, everyone trusted Conan's reasoning ability and believed that he could lead everyone to make the best choice.

Conan did not disappoint everyone, and when he reraised his head, he had a smile on his face that had succeeded in reasoning.

"Wait for me here, I'll go and verify if my reasoning is wrong." Conan replied after checking that the flashlight on his watch was working properly.

"What if I get lost?" Tadao was a little surprised by Conan's presumptuousness. "It is said that there are many routes in this kind of place, and if you are not careful, you will get lost..."

"I'm not wandering around without purpose," Conan said, holding his notebook and pen, turning on his flashlight, as he climbed down the vines. "Wait for my good news, it will be in about 10 minutes."

With that, Conan disappeared into the hole.

。。。

Waiting, waiting like years. Both the little ones and Tadao had already climbed down from the vines and stood by the mouth of the cave waiting for Conan to return.

"How many minutes?" Ayumi worried.

"Maybe 15 minutes... Mitsuhiko echoed worriedly. "Didn't Conan say it would only take ten minutes...

"Calm down," Tadao said, glancing at his watch. "It's only been eight minutes and thirty seconds, and you're too impatient."

"But why hasn't Conan come back yet... Ayumi was still a little worried.

"I didn't come back!" Tadao's voice suddenly sounded.

"Huh?" Everyone looked at Tadao blankly, but found that Tadao was also at a loss.

"Huh?" Tadao looked at the other man's gaze in surprise. "I didn't say anything...

"Conan has returned." Tadao's voice rang out again.

“。。。” Mitsuhiko blinked, because he saw that Tadao's lips didn't even move, it couldn't be that he was talking, and how did he hear how to think that this voice was coming from behind, that is, in the direction of the entrance of the cave... Isn't that right?

Mitsuhiko hurriedly turned around, only to see Conan, who was holding a bow voice changer, smiling at all of them.

"Gentlemen," Conan said in his own voice. "I'm back, my reasoning..."

"That's right!"
