Stay away from Conan.

For a long time, the secret of Keizaburo Axe's treasure was actually related to the swordsmith "Tokugawa Eiryu". This was obviously a bit puzzling. After all, Tokugawa Eiryu was not a famous swordsmith, and only six short swords were handed down from him. However, these short swords were collected by Keizaburo Axe, a super fan of Hijikata Toshizo.

Therefore, although these short swords have their value compared to many other collections, what is the relationship between Tokugawa Eiryu and Hijikata Toshizo? Why did the short swords he forged be collected by Axie Keisaburo along with those collections related to Hijikata Toshizo?
Therefore, it seems that this doubt may be solved simply because these six short swords were specially forged by Axie Keisaburo at Tokugawa Eiryu to hide clues to the secret of the treasure, right?

So, following what "Okita Souji" said, Conan and Hattori Heiji nodded, feeling that this statement made sense, so Hattori Heiji continued to analyze:
"So from this point of view, there must be a reason why it has to be made into these shapes... It is very likely that the secret lies here."

As he said this, Kawazoe Zenkyuu looked at the shapes of the eyelet holes on the four short swords, and drew the four shapes on the blackboard respectively.

It can be seen that the shapes of these four eyelet holes are a five-pointed star, a perfect circle, and two semicircles, and the two semicircles are in different directions, appearing symmetrical.

Looking at these four shapes, Nakamori Ginzo was puzzled and said helplessly:

"Even so... I have no idea what these shapes mean..."

"that is……"

After drawing these shapes, Kawazoe Zenkyuu stared at these patterns in confusion.

In this way, everyone present also focused their attention on these shapes and began to think seriously. In this regard, "Okita Souji" couldn't help but think of the stars in the night sky when looking at these patterns, so he couldn't help but say seriously:
"It should be... the moon, right?"

"Ok?"

Upon hearing this, Conan and Hattori Heiji stopped their original thoughts and turned to look at "Okita Souji".

And Okita Souji, who seemed to be very touched by the astrology, continued slowly:
"The moon shining in the night sky... When I was flying in the sky before, I always used the moon as a landmark."

After saying this with emotion, "Okita Souji" stood up and began to analyze the six short swords:
"The knife without the eyelet should represent the new moon, the semicircle represents the waxing moon, the other represents the waning moon, and the perfect circle is naturally the full moon."

In this way, after giving the meaning of these eye holes, Conan and Hattori Heiji on the side knew that what he said made sense, but at this moment they could only look at him a little awkwardly -

After all, he was the one who exposed himself...

——"Oh? Flying in the sky?"

Regarding "Okita Souji's" statement, Nakamori Ginzo's focus was not on the interpretation of the secrets on the sword, but he noticed the key problem in what he said before:

"You mean, you can fly in the sky?"

Interestingly, Ginzo Nakamori looked at "Okita Souji" and asked seriously.

"Why--

"No, no! It's just a metaphor, a metaphor!"

After realizing that he had said something wrong, "Okita Souji" hurriedly said to make amends:

"When I practice kendo, I often think of the scene in Bruce Lee's movie where he points to the moon, 'Don't think! Feel it!' At these times, I feel like I've really flown up to the sky and seen the moon!"

With his thoughts racing, "Okita Souji" gave this explanation.

Seeing him say this, Nakamori Ginzo didn't know what to say for a moment, but just had a little doubt, and at the same time Conan asked:

"Mr. Axie Keizaburo is a fan of Hijikata Toshizo, right? If so, does this have any connection with Hijikata Toshizo?"

At this point, Kawazoe Zenkyu turned his gaze back from "Okita Souji" and said:

"Makes sense."

He wrote "Higata Toshizo" and "Tsuki" on the blackboard. However, at this point, everyone's analysis seemed to have reached a deadlock.

"No, I don't understand it at all... And if those patterns are the moon, why are there stars..."

After everyone was thinking and silent for a long time, Nakamori Ginzo seemed to have given up and said helplessly.

Seeing this, Kawazoe Zenkyu also glanced at the people present. After seeing that no one seemed to have any ideas, he pushed his glasses slightly and suddenly seemed to remember something and said:

"Ah! Speaking of Hijikata Toshizo and the stars, it should be Goryokaku, right?"

"Goryokaku!"

Instantly, everyone was shocked when they heard this term——

Yes, Hakodate, Hokkaido. When talking about Hijikata Toshizo, how can we forget Goryokaku!

but……

What else? The stars can be matched, but what about the moon?

"But if it's Goryokaku, what does it have to do with the moon? And that piece of paper... hasn't been used yet."

Hattori Heiji said in confusion -

"Then maybe it's the "Toyotama Hakujuku"?"

Then, Kawazoe Zenkyu continued:

"I just tried searching the Internet with Hijikata Toshizo and Moon as keywords, and found this..."

As he said this, Kawazoe Zenkyu showed the search interface on his phone and smiled complacently...

……

"So, Akechi-kun, are you planning to use this drone to take a picture of the entire Mt. Hakodate?"

At the same time, while Conan and others were analyzing clues about the knife at the Hakodate Police Station, on the other side, Gao Yuan and others had arrived at Hakodate Mountain by helicopter.

So, looking at the four-wing drone that Gao Yuan and Xiao Ai had made overnight, Tie Zhuyu and the others asked in surprise -

After all, judging from its appearance, this thing is too simple, and it is hard to believe that it can achieve the purpose Gao Yuan said.

At the same time, Ooka Hongye said:
"If I want to take pictures of Mount Hakodate, I can use a helicopter to help."

"I'm afraid a helicopter won't work."

But Gao Yuan rejected this proposal:
"If we use a helicopter, the impact will be too great, and we can't get too close to the mountain to fly and shoot... Don't worry, I know what I'm doing!"

As he said this, Gao Yuan was confident that this thing he had rushed to make overnight could achieve the functions he wanted to achieve.

After all, the battery life should be enough to cruise the entire height of Mount Hakodate with at least three battery changes.

All you have to do is capture the entire mountain, and the rest will be analyzed by the main computer in the basement of Akechi's house in Tokyo and the artificial intelligence applet!
Through artificial intelligence processing of the image, the specific details of the mountain are simulated and calculated to find out where the military base may be hidden.

The military base of the last century should not be difficult to find. (End of this chapter)
