Stay away from Conan

Since the helicopter is a convenient means of transportation, it didn't take long for Gao Yuan and others to find a place to land near Goryokaku, and then they got off the helicopter and started to wander around Goryokaku.

In this regard, Ooka Momiji, Tetsu Moroha, and Mitarai Yukina were originally here for fun, so since Goryokaku is also a good attraction, they naturally went to play together after coming here.

As for Gao Yuan and Xiao Ai, although Gao Yuan's purpose was to see if there were any clues about Keisaburo Axie's treasure in Goryokaku, he was essentially just wandering around here, so he simply followed everyone.

This Western-style fortress built in the 19th century, with its unique five-pointed star shape, looks particularly spectacular in the approaching dusk.

Starting from buying tickets and climbing up the Goryokaku Tower, on the observation deck of this high tower, after Ooka Momiji and Mitarai Yukina introduced the scenery they saw, Hakodate Mountain, Tsugaru Strait and even the Yokozu Mountains in the north came into view, which are excellent tourist attractions in Hakodate City. However, to be honest, it is still a good idea to look down from a distance. You can clearly see that the entire star-shaped fortress has a perfect five-pointed star shape.

Among them, located in the center is the Hakodate Magistrate's Office, which is a building with a very Edo-era style. However, according to Ooka Momiji, there are no ancient buildings here, because this place was originally destroyed after the decline of the Tokugawa Shogunate, but was rebuilt in recent years.

Therefore, after learning this, Gao Yuan couldn't help but unexpectedly think that if Axie Keisaburo wanted to hide some secrets in Goryokaku, this newly built building could obviously be directly excluded.

Let's review this from a historical perspective. If Keizaburo Axie was responsible for researching secret weapons during the war, then the place where he wanted to hide the secret must also belong to that era.

So...

The treasure hidden by Keizaburo Axie may be a secret place for the development of secret weapons, clues related to Hijikata Toshizo, and the star-edged sword that should have been collected by the Axie Foundation but disappeared...

Combining these clues, Gao Yuan can think of this -

If the way Keizaburo Axie hid the treasure is related to Hijikata Toshizo, then it is very likely related to Goryokaku, and the five-pointed star shape of Goryokaku is very likely related to the star-edged sword that Hijikata Toshizo used mentioned by Mitarai Souaki. After all, the same five-pointed star shape is a rare coincidence. If it were me, I would also be surprised by it.

In this way, the star-edged sword combined with Goryokaku is very likely to be the real hidden clue related to the secret of the treasure, rather than the so-called six short swords forged by Higashikubo Ronglong that have been leaked now.

The short sword of Tokugawa Eiryu is probably just a rumor deliberately brought out to confuse people. After all, the time when this clue appeared is also suspicious.

This is also what Mitarai Souaki thinks.

Moreover, if the clue is on Tokugawa Eiryu's short sword, then Kuroba Toichi at that time would have almost no chance to search further. After all, the whereabouts of the six short swords are different. If Kuroba Toichi had obtained these six short swords, he should have left clues.

Therefore, if you think about it this way, if you want to find the treasure hidden by Fue Keisaburo, you should first find the Star Edge Sword. Then where would Fue Keisaburo hide the Star Edge Sword that is not in the collection of the Fue Foundation?

Would he simply hide it directly in a place related to Goryokaku?

After all, if we go back to Hijikata Toshizo, in Hakodate, there is only Goryokaku...

However, the Hakodate Magistrate's Office in the center of Goryokaku is no longer a building from the time of Keizaburo Axie. As for the Goryokaku Tower where he and others are now...

With a little investigation, we can know that its original construction year was after the war, so Keizaburo Axie could not have hidden things here.

So, where would the place be that fits that era?

Thinking so, in this Goryokaku Tower, Gao Yuan and others looked at the scenery on the observation deck, and then visited the bronze statue of Hijikata Toshizo who died in the Battle of Hakodate, as well as the model of Goryokaku when it was completed, and the items explaining the history of Hakodate and Goryokaku.

At this point, looking at the historical explanation of Goryokaku, Gao Yuan couldn't help but find a point that was a bit of a concern -

It is said that when Goryokaku was built, the northeast direction corresponded to the ghost gate, so a shrine was built there, named Toshogu.

Therefore, after seeing the shrine, Gao Yuan suddenly realized that it seemed to be a good choice to worship something in the shrine, and the shrine was built much earlier than the war period of that year.

However, after further research, Gao Yuan found that the main hall of the Toshogu Shrine at that time had been burned down as early as the Hakodate War, and the Toshogu Shrine at that time no longer exists.

However, there is indeed a Toshogu Shrine in Hakodate now, which seems to be the Toshogu Shrine of that year. It was built just after the Hakodate War and before the war of the last century, so it fits Gao Yuan's speculation on the time.

Therefore, although there is no evidence, Toshogu Shrine...

It is worth a visit, anyway, just take it as a trip.

In this way, after following Ooka Hongye and others to visit Goryokaku briefly, Gao Yuan proposed to go to Toshogu Shrine, so everyone took a helicopter again and came to Toshogu Shrine in Hakodate.

Here, with a try-it-out mentality, Gao Yuan met a young shrine maiden in this shrine——

"Excuse me, are you here to worship?"

It was almost dusk at this time, and the young shrine maiden felt a little strange when she saw Gao Yuan and several other girls coming here, but she still asked this professionally.

In response, Gao Yuan thought about it and asked:

"Sorry, I'm not here to worship. My name is Akechi Gao Yuan, I'm a detective, and I came here... I want to ask, do you know anything about Toshogu Shrine related to Hijikata Toshizo... or, Mr. Axie Keizaburo?"

So, just with a try-it-out mentality, thinking that if Axie Keizaburo really handed the things to the shrine for safekeeping, maybe the people in the shrine would know, so he asked this question.

As a result, facing Gao Yuan's sudden question, especially after Gao Yuan mentioned the name of Axie Keisaburo, the young shrine maiden's expression obviously changed -

First, she was slightly surprised, then silently closed her eyes and hesitated for a moment, and finally, the shrine maiden glanced slightly, held her hands in front of her, and said slowly with a little force:

"No. We don't have that kind of thing in our shrine..."

"No? Or is it gone?"

However, with the shrine maiden's actions, Gao Yuan's thoughts were cleared up, and he suddenly asked directly...
