"But if we really want to talk about it, brother Tadao is here to look for treasures, right?" Just when Sage was about to take the detective team back to her room, Conan looked at Tadao's slightly red face and said calmly.

"Ah?" Tadao was stunned.

"You said you are a treasure hunter by profession, right?" Conan shrugged.

"Ah..." Tadao smiled bitterly. "That's true..."

"Could it be that there is a treasure here!?" Mitsuhiko said excitedly.

"Treasure?" The tall man had just taken off his shoes with his friends and walked into the hall. At this time, he looked at Tadao curiously. "Friend, would you mind telling me about it?"

"Ah..." Tadao looked at the tall man's eyes and blinked. "Okay... let's find a place where we can sit down and talk. Let's go to my room."

"Go to our room." The tall man said. "Just think of it as my lecture fee."

"Ah..." Shaxue suddenly remembered something. "Two guests, you haven't registered your names yet!"

"Oh..." The tall man scratched his head. "Well... my name is Kimura Ichiro." Then he pointed at the short man. "That fat man's name is Tanaka Jiro."

"How can I gain weight!" Tanaka Jiro said speechlessly.

"..." Qianyu observed Tanaka Jiro's figure - although he was not thin, he was not very fat after wearing the jacket. In addition, after he entered the room and unzipped the jacket, looking at his exposed neck,

He should be a muscular man.

"Since you work here, you should be familiar with the rooms here, right?" Kimura Ichiro glanced at Tadao. "Take us there."

...

"Well..." Sitting in Kimura and Tanaka's room, Tadao glanced at the kids next to him. "Since there are kids in the audience, do you two mind if I start with the basics?"

"Anyway, it's still a long time until nightfall," Tanaka originally wanted to say something, but Kimura beat him to it. "You might as well educate them a little bit, so that they won't interrupt and ask if you have anything to say when you are talking about the core content.

It’s a matter of nutrition.”

"We also know a lot about treasures!" Yuantai said unhappily. "It's just hidden treasures!"

"Why should the treasure be hidden?" Tadao asked with a smile.

"Huh? This..." After Yuantai muttered something sarcastic, he became silent for a moment.

Tadao looked at the other people, and Ayumi and Mitsuhiko didn't know the answer either; Haibara Ai pretended not to hear anything and looked straight ahead; Qianha and Conan looked at each other, shrugged and said they didn't know the answer - this

The question is really a bit big and not easy to answer.

"Treasures are treasures that ancient people hid in hidden places," Conan began to explain. "Because Japan did not have institutions like banks during the Warring States Period, there was no channel to store large sums of money - in the Far East next door,

Around 713 AD, that is, in the early days of Emperor Xuanzong's founding of the Tang Dynasty, there were already cabinet shops that could store large sums of money for just paying rent - so it is the safest to bury your treasure in a place that only you know. Because no matter how much

A tight defense may be breached, but the treasure whose location no one knows can be well preserved. However, the treasure hunter may die suddenly due to a sudden illness or accident, and there is no time to reveal the location of the treasure. In this case, the treasure becomes

No one knows where the treasure is anymore.”

"Yes," Tadao smiled gently. "So it is our job to find these treasures~"

"Why does it sound like fishing for gold in a haystack..." Mitsuhiko tilted his head and said in confusion. "Japan is so big, it must be difficult to find treasures!"

"Don't underestimate the quantity and quality of Japan's treasures!" Tadao retorted with a smile. "Do you know how Japan is described in Marco Polo's travel notes?"

"netgu, the land of gold."

"Netgu? Is this the Italian meaning of the Golden Country?" Ayumi asked curiously.

"Italian shouldn't have this word," Haiyuan Ai, who had been silent all this time, shook his head. "Arabic shouldn't have the sound p. I don't know about Chinese and Mongolian. Other languages ​​shouldn't be in Marco Polo's language library."

"Netgu means 'Japan' in Chinese (the Middle Chinese pronunciation of Japan)..." Conan curled his lips, and then turned to Tadao. "Indeed, the Japan he wrote was extremely rich, but...

There is still doubt whether he has really been here!"

"Yes..." Qianyu nodded. "Although there are accurate accounts of some events, as Heigl and Kronas (sceptics of Marco Polo's travels) said, there are many flaws in Marco Polo's travels.

, many scholars in the Far East have also investigated and found that there is no trace of Marco Polo in historical materials."

"But there is no doubt," Tadao looked at Conan, Qianha and Haibara Ai in surprise, and then said. "Many warlords in Japan do have human wealth lost underground. For example, the Edo shogunate was desperately looking for it, and the North

The treasures of the Yuki family buried by Yuki Haruto in Kanto; the imperial gold buried by the Tokugawa shogunate in Mount Akagi in Gunma Prefecture; and the military gold of Toyotomi Hideyoshi buried in Tada Ginzan in Hyogo Prefecture, etc.”

"Are you looking for the Takeda family's treasure?" Conan raised his eyebrows. "But if I remember correctly, there have been large-scale excavations in several gold mountains here in history... and even

There were thousands of people digging for gold, but they all found nothing."

"But if they didn't find the treasure because there was no treasure here at all, then it's hard to explain the more than ten gold bars at the end of the Meiji period," Qianyu spread his hands. "That's not a small amount."

"Are you so knowledgeable?" Tadao exclaimed. "You actually know all this."

"What are you talking about?" Genta asked, poking Conan.

"At the end of the Meiji period, someone found the body of a man who fell to death at the foot of the nearby Kurokawa Gold Mountain," Conan explained. "There were more than a dozen gold bars on his body, so it sparked a treasure hunt craze."

"More than ten? How many are that?" Mitsuhiko asked.

"At the end of the Meiji period, the world currency was the pound, and the United Kingdom adopted the gold standard system. One pound was equivalent to 7.32 grams of gold. If there were more than ten pounds, it might be about 600 pounds."

"600 pounds?" The little guys were obviously disappointed with the answer. "That's less than 100,000 yen, right?"

"The 600 pounds at that time was very expensive..." Qian Yu curled her lips. "In 1918, the average weekly salary in the UK was 1.5 pounds under the condition of 52 hours of work. It would be even lower in the late Meiji period, so 600 pounds

It can be said to be the income of ordinary British people in ten years."

"So many!" the little ones exclaimed together.
