Stay away from Conan

In this way, based on the limited clues and analyzing the starting point of this whole thing, which is the truth about Keisaburo Hatie's so-called treasure, Gao Yuan probably came up with a guess as to what this treasure is -

Keisaburo Hatie was probably requested by the Japanese authorities back then to secretly research some kind of weapon. As a result, the weapon was not successfully developed until Japan's defeat.

As for the secret of the so-called treasure, it is probably the place where Keisaburo Hatie secretly developed the secret weapon. After all, as a secret weapon that needs to be developed secretly, in order to develop this thing, there must be a secret place that cannot be discovered by outsiders. …

Therefore, if you think about it this way, that place should be in an inaccessible place.

And in a place like Hakodate, as a coastal city, where would Keisaburo Hatie find a place?

Is it a hidden island, or simply hidden in the mountains?

In short, since the war until now, that place has not been discovered. In addition to being hidden, there is also a high possibility that it is built in a place that is inconvenient for development. Therefore, subconsciously, Gao Yuan could only think of the surrounding sea areas. The hidden island or the only mountain in Hakodate City...

However, at this point, it is only speculation, and it is impossible to really find the location of Keisaburo Hatie's treasure. However, based on these, one thing that is more certain is that if everything is as I thought, then the secret of the treasure will not be found. It was normal for it to be reported, but the sudden appearance of Tokubo Eiryu's clues became even more suspicious.

Even if Keisaburo Hatsue borrowed some things from Toshizo Hijikata, whom he admired, in order to choose this secret location for developing weapons, are these six short swords forged by Tokubo Eiryu a bit far-fetched?

Therefore, Gao Yuan felt more and more that the real secret had nothing to do with the six daggers, and that the news linking the search for the treasure to the six daggers of Tokubo Eiryu was more like a deliberately spread rumor.

Therefore, if we think about the problem of Kuroba Toichi back then, Kuroba Toichi must not have been able to get together six daggers at that time. Moreover, this clue about Dongwa Eiryu only appeared recently, and it definitely did not exist back then. So when Black Feather Pirates wanted to find the whereabouts of the treasure, he must have had other ideas——

But, what is this idea...

Maybe try to find clues from history.

But……

Thinking of this, Gao Yuan couldn't help but feel helpless——

When it comes to the history of Japan, I know absolutely nothing about it! Even though Keisaburo Hatsumue may refer to Hijikata Toshizo's story to find the secret location, even for a figure like Hijikata Toshizo, his knowledge is extremely limited.

So, at this time, we can only try to read history...

Or, can you ask someone?

So, just as Gao Yuan was thinking this, he heard the sound of a helicopter passing near him again...

…

The time gradually turned into the evening, and they got off the train at Yukawa Station in Hakodate. Xiaolan and Kazuha also took advantage of today's detectives to investigate, and they went around Hakodate. As for Yuanzi, she still had to continue to deal with the transfer of relevant collections with the Ax River Consortium, so she did not go out to play with Xiaolan and the others.

"Sorry, I was so happy that I accidentally sat at the terminal..."

In this way, I originally wanted to take the tram to visit Hakodate together, but now I took the train directly to the terminal before getting off. Kazuye seemed to be a little unsatisfied and apologized to Xiaolan.

Regarding this situation, Xiaolan couldn't help but follow:

"No, anyway, I just wanted to experience the tram."

With that said, the two people who got off the tram stood on the platform and couldn't help but look at each other and smile.

However, at this moment, a car drove up on the road next to it, stopped at the station where Xiaolan and the others were, and honked the horn, attracting Xiaolan and the others' attention. Xiaolan and the others couldn't help but look towards That car, it was discovered that it was the vehicle driven by the police officer Kawazoe Zenku whom I had seen not long ago.

As the driver's window was pulled down, Kawazoe Zenku's figure appeared in the car, and he couldn't help but say to Xiaolan and the others:

"Huh? Are you with Detective Akechi and the others?"

Because during the day, thanks to Gao Yuan and the others, Kawazoe Zenku had met Xiaolan and the others, so now, as if by chance, Kawazoe Zenku came over to ask in good faith, feeling that it would be getting late, and Xiaolan and the others were at the tram terminal, so the traffic might be a little inconvenient.

So, just like that, Kawazoe Zenku offered help to Xiaolan and the others, saying that he could give them a ride. After inviting them to get in his car, Kawazoe Zenku said that before sending them back, he would stop by. Go check out a place.

In this way, Kawazoe Zenku took Xiaolan and Kazuye to a mansion called "Fukujo"——

And here, Hattori Heiji and Conan had already arrived here first on motorcycles.

——"This is it."

Looking at the surname "Fukujo" written on the door sign outside the mansion, Hattori Heiji couldn't help but say this.

After learning the whereabouts of the last two daggers belonging to Tokubo Eiryu from Kaitou Kidd, and learning the address of the high school teacher named Fukuro Ryohei through police channels, Hattori Heiji and Conan rushed there directly. Come over.

Regarding this, Conan couldn't help but ask Hattori Heiji when he saw that he was the only two people here:

"Have you told Inspector Nishimura all the details about Fukujo?"

"Of course. I told him to give him the knife and let him come here to join us."

As Hattori Heiji said this, he saw Kawazoe Zenkyu's car behind them also drove up, just a moment later than him and the others-

"Look, it's coming."

Hattori Heiji said this, and as Kawazoe Zenkyu's car drove up to him, the window on the back seat of the car was open. Xiaolan and Kazuha were sitting in the back seat. Seeing Conan and Hattori Heiji here, Kazuha was obviously a little surprised:

"Ah, Heiji?"

"Kazuha? Why are you here?"

Hatori Heiji asked back, also a little surprised.

"I'm so sorry."

At this time, Kawazoe Zenkyu, who was driving the car, got out of the car and explained to Hattori Heiji:

"I should have taken them to the hotel, but because of the things here, I came here..."

As he said this, Xiaolan got out of the car and said politely to Kawazoe Zenkyu:

"Don't be so polite, don't worry about us, just deal with the matter first!"

As he said this, everyone suddenly saw a person coming out from the corner. After seeing Hattori Heiji and others, he waved to everyone and said:

"Ah! I found you!"
