Stay away from Conan.

"Okita!"

Hearing Okita Souji's voice at this time, Xiaolan couldn't help but look in the direction of the voice, only to see a taxi parked beside her. After the rear window of the taxi was rolled down, Okita Souji appeared in it, smiling at Xiaolan:

"I was planning to look for you guys, but I ended up meeting you here! What a coincidence, Xiaolan!"

Souji Okita said to Xiaolan:

"I'm looking at you guys, is there anything I can help you with?"

Regarding the current situation, Okita Souji also saw some clues and said.

In this regard, seeing Okita Souji appear in a taxi, Xiaolan suddenly realized that Okita Souji's appearance really provided her with great convenience, so Xiaolan didn't think much about it, and stepped forward to Okita Souji and said:

"Okita! You've come just in time, can you help me? We're going to chase someone!"

As he said this, Kazuha hurried over and said to Okita Souji:
"Yeah Okita, can you help us?"

In response, he glanced at Kazuha, then turned to Xiaolan seriously and smiled:
"Of course you can, Xiaolan!"

Having said that, Okita Souji invited Xiaolan and Kazuha to get in the taxi together, and then said to the driver:
"Where to go next to listen to them."

So, Xiaolan immediately said:

"Excuse me, driver, please catch up with the one in front..."

Xiaolan was speaking anxiously, and then she looked in the direction where Fucheng Sheng left, only to find that Fucheng Sheng had disappeared long ago!
From the beginning, the delay had caused Fucheng Sheng, who was driving away, to drive too far away and he could no longer be seen.

In this regard, the driver was also confused and didn't know what Xiaolan meant by the front. In the end, Xiaolan and Heye could only suggest:
"Let's drive forward! We'll try to find it..."

Now that things have come to this, this is the only way...

……

"Mr. Akechi! How could you…"

At the same time, in Goryokaku, after dealing with Kuroba Kaito's infiltration into Monkura, Gao Yuan thought for a while and finally chose to come to Goryokaku to meet up with Conan and the others.

Now, at this point, in addition to the question of where Keisaburo Axie's treasure is, the key is to lure out the gate and rescue the hostages.

So, facing Conan and Hattori Heiji's doubts, Gao Yuan just said:

"Of course, we need to solve the current mysteries one by one as much as possible!"

Having said that, Conan and Hattori Heiji nodded seriously, and then said helplessly:

"It's just that we have done our best to search Goryokaku, but we didn't find anything..."

"Besides, without the Star-Edged Sword, I don't know how to connect the Star-Edged Sword to Goryokaku..."

Hattori Heiji and Conan each said this.

As a result, Gao Yuan said:

"The so-called Star-edged Sword, in reality, isn't it just a samurai sword with a five-pointed star-shaped guard? According to the items collected by the Fujiang Group, there is a screen with the shape of the Star-edged Sword's guard and the width of the blade. It is not difficult to deduce the actual model of the Star-edged Sword from this! And the length of the samurai sword should be similar according to the standard." Having said this, Hattori Heiji couldn't help but have an idea and said:

"Based on the old photo of the Star-Edged Knife, the model of that Star-Edged Knife... generally speaking, the length of the blade is about 70 centimeters."

"So, if a samurai sword has a basically fixed length and the shape of the blade can be directly copied from the screen, even if the original body of the sword is lost, the appearance of the sword can be basically restored."

Gao Yuan said this, took out his phone, and showed Conan and the others the screen that he had asked Suzuki Sonoko to take a picture of.

The photo specifically captured the shape of the five-pointed star-shaped blade left by the star-edged knife on the screen, and two rulers were placed in the horizontal and vertical directions as reference systems to determine the specific external shape of the blade.

In this regard, Gao Yuan said:
"Now, with the data of the Star Blade, and the shape of Goryokaku here, plus the glass-like bottom of the hot air balloon in the two old photos, it should be easy to guess."

At this point, facing Gao Yuan's clear hint, Conan and Hattori Heiji immediately understood the key points -

"Could it be that when Keizaburou Axie boarded the hot air balloon with the Star Blade, he used the glass at the bottom to make the Star Blade and the shape of Goryokaku completely overlap in his sight, and used this to determine the height!"

Hattori Heiji said in surprise.

"It's a very possible guess. Otherwise, it's impossible to explain why the bottom of the hot air balloon in the photo is made of glass."

So, seeing that there was only one step left to solve the puzzle, Conan couldn't help but say:
"Well, if that's the case, we just need to copy the model of the Star Blade, and then find a hot air balloon to recreate Keisaburo Axie's actions at that time, and then we should be able to..."

"No need to go through so much trouble!"

But at this point, Gao Yuan directly rejected Conan's idea of ​​doing an experiment to reproduce Keisaburo Axie's situation at that time. After all, there was no need -

"With the actual data of Goryokaku's appearance, the model data of the Star Blade, and the basic imaging principle of the human eye, as long as a mathematical model is established, the specific height of the hot air balloon can be basically calculated! Although there will be some deviations due to actual observation by the human eye, it should be roughly the same in detail—

"In short, the actual height is probably within this range..."

Gao Yuan continued to speak, and his calculation model and calculation results were displayed on his mobile phone——

"At this height, there is basically no need to calculate in detail! Because in the entire city of Hakodate, there is only one place where a building can be hidden at this height!"

Gao Yuan said affirmatively, and in his heart he was very sure of his own thoughts -

That's right, it can only be in Mount Hakodate. There is nothing wrong with the speculation I made based on the map of Toshogu Shrine. The only difference is that without the Star Edge Knife, I can't be sure where exactly that place is in Mount Hakodate.

However, I found the exact location by brute force after going through the entire Mt. Hakodate. Therefore, there was no need to use the Star Edge Knife to determine the exact location. I skipped the decryption process and already knew where the treasure was.

I can only say that the location of Keisaburo Axie is not difficult to find. In fact, as long as you guess that it is a military base, you can basically think that the place where Hakodate City may have a secret military base is in Hakodate Mountain.

So, having said this, Conan and Hattori Heiji suddenly understood, and were thinking about what to do next -

"It's finally here!"

After Gao Yuan suddenly said this, Conan and Hattori Heiji were both shocked, and then they saw Kadokura's men driving here -

"Kadokura? Why is he here?"

Conan and Hattori Heiji were both shocked. (End of this chapter)
