Stay away from Conan.

"Now Kadokura has gone completely crazy! Mr. Fukushiro Ryohei must have been kidnapped by him, and now he is about to shoot and kill the police. If he can't find the whereabouts of the treasure, I'm afraid he will do something even crazier!"

Following Conan's words, Hattori Heiji also said

"Furthermore, Fukushiro Seiya was taken away by the police for investigation because of the fingerprints of lawyer Kugaki on his scabbard. This matter has become more complicated."

Conan continued.

As a result, after listening to Conan and Hattori Heiji's answers, Gao Yuan knew that Fukushiro Ryohei was the owner of the last two Tokugawa Eiryu short swords, but he had never seen him. So now he knew that the other party might have been captured by Monkura on purpose, so he couldn't help but ask Conan and Hattori Heiji what was going on, and how Fukushiro Sei, a person Gao Yuan didn't know, was related to the murder of Kugaki Sumito.

At this point, Conan and Hattori Heiji explained to Gao Yuan what happened after they went to Fukushiro's house yesterday.

Then, Gao Yuan could not help but ask, knowing that the two Tokugawa Eiryu daggers owned by the Fukjo family were actually given to the great-grandfather of the Fukjo family by Fukjo Keisaburo himself when he was in Fukjo, and he subconsciously asked:
"So now, have you found more clues about finding the treasure?"

In response to this, Conan, who was already prepared to exchange information thoroughly, told Gao Yuan the clues such as the fire of Goryokaku during the war and the Star-Edged Sword, indicating that the treasure to be found should still be related to Goryokaku.

However, Gao Yuan was unable to make any judgment on Conan and the others' guess.

After all, he found the treasure directly through brute force cracking, and there is no more logic in it. And the treasure may not be what Monkura wants. If he lets Monkura know now that the treasure is just a cipher machine that has no strategic value at all, Monkura may even think that he is deceiving him. Gao Yuan thought about it and decided not to tell everyone about his discovery for the time being, so as not to confuse Conan and the others' analysis.

But even so, can we still make inferences based on new clues without the Star Edge Knife?
Moreover, for Gao Yuan now, what he cares more about is Fukushiro Ryohei and Fukushige Sheng than the treasures.

Because he was not clear about the affairs of the Fukushiro family originally, but now that Fukushiro Ryohei and Fukushiro Seito have gotten into trouble, Gao Yuan vaguely felt that something seemed to be wrong.

Just as he was about to think about it, Kawazoe Zenkyu came to the hospital in a hurry, waved an envelope in his hand at Inspector Nishimura, and said anxiously:

"Inspector Nishimura! Important discovery..."

As he said this, Kawazoe Zenkyu hurried over, came in front of the crowd, took a breath, and looked very rash.

Seeing this, Inspector Nishimura was a little dissatisfied with Kawazoe Zenkyu's hasty coming here. After all, after Officer Nakamori Ginzo got into trouble, Kawazoe Zenkyu had been gone for no apparent reason, and he just came back now.

But after thinking about it, Inspector Nishimura couldn't help but ask:

"What important discovery?"

Although he said so, Inspector Nishimura actually did not think that Kawazoe Zenkyu, who had been away for such a while, could bring back any extremely important clues that could turn the current situation around.

In response to this, Kawazoe Zenkyuu handed the envelope in his hand to Inspector Nishimura after hearing what Inspector Nishimura asked, and then said:

"It's like this. We found the personal belongings that Kugaki Sumireto had stored away and didn't bring with him. Among them, we found these two old photos..."

"Photos?" Upon hearing this, Inspector Nishimura, Gao Yuan and others came over and looked at the two photos taken out of the envelope. They found that they were old photos taken in the last century. The person in the photo was Keisaburo Axie wearing the military uniform of the time.

In one of the photos, Axie Keizaburo is at Goryokaku, holding a samurai sword with a five-pointed star-shaped blade in his hand, which should be the star-shaped sword; and in the other photo, Axie Keizaburo is on a hot air balloon, looking into the distance with a telescope, and there is a bright reflection at the bottom of the hot air balloon...

Just like that, seeing that it was an old photo of Axie Keisaburo, and there was Keisaburo's signature on the back of the photo, which involved Goryokaku and the Star-Edged Sword, Conan and Hattori Heiji were shocked:
"Could this be the key clue to unlocking the secret of the treasure?"

"But what does this mean?"

Inspector Nishimura was puzzled, but he had to admit that the clues that Kawazoe Zenkyu had obtained seemed to be quite important.

Seeing this, looking at the two photos, Gao Yuan thought for a moment and then said casually:

"Are you going to bring the Star Edge Knife on the hot air balloon?"

Because he saw the photo that specifically showed Keisaburo Axie coming to Goryokaku carrying the Star-edged Sword, and combined with another scene where Keisaburo Axie boarded a hot air balloon, Gao Yuan had already found the location of Keisaburo Axie's treasure, so he knew that if he was not mistaken, then if he followed the normal clues, he should find Mount Hakodate.

However, these two photos were taken in Goryokaku and should have nothing to do with Mt. Hakodate, but...

In the photo of the hot air balloon, Keizaburou Axue was looking into the distance with a telescope. Judging from the direction of the telescope in Keizaburou's hand, he should be looking straight ahead. Gao Yuan immediately understood that this indicated that Keizaburou Axue was looking in the direction of Mount Hakodate.

After all, the terrain of Hakodate City, after flying into the air, at this altitude, the only thing you can see when looking straight ahead is Mount Hakodate.

6◇9◇Book◇Bar

In other words, it is very likely that the meaning of these two photos is that someone is on Goryokaku side, flying to a certain height in the sky, looking straight at Mount Hakodate, and the place they see is where the treasure is?

Suddenly, Gao Yuan thought of this possibility and felt that it made sense, because it matched the place he actually discovered.

This is the height of the hot air balloon...

Goryokaku, the Star-rimmed Sword, and the reflections from the bottom of the hot air balloon...

——"You think that the shape of Goryokaku is the same as the hilt of the Star-rimmed Sword, both of which are five-pointed stars, could this be a key clue? Compared to the other six short swords of Tokubo Eiryu, only this one has a special hilt and was specially hidden in Toshogu Shrine."

Gao Yuan said tentatively:

At this moment, Gao Yuan felt that many things seemed to make sense. If other people were not able to use artificial intelligence to analyze the mountain topography and crack the location of the secret military quarter like he did, then among the existing clues, the only clues that could be used were the Star Edge Knife and the two photos...

As for the others, they may seem useful, but they are actually unimportant and dispensable...

As Gao Yuan was saying this, Kawazoe Zenkyuu, who was standing beside him, looked at Gao Yuan with a slightly sharper look... (End of this chapter)
