Detective Conan: The Ultimate Growth Space

When he said this, the people from the tour group standing around him all looked surprised.

Only Zhiyong noticed it; the others did not.

Officer Da Long closed the scroll and placed it among the belongings. Then he picked up the fragment.

"And what is this fragment?"

Heiji looked at it and said, "This looks like a fragment of pottery."

"Really?" They turned around and saw that it was Kazuha.

Kazuha continued, "This fragment, could it be the same one found on the charred corpse in the previous case? I remember last night, when your father was driving my father home, they talked about this in the car."

Heiji asked, "What did they say?"

Kazuha replied, "They said that a piece of this fragment was found on the charred corpse that was discovered thirteen years ago, and on the charred corpse that was discovered not long ago. The fragment that was found earlier also had the number 848 written on it."

Heiji asked in confusion, "Eight hundred and forty-eight? What does that mean?"

Kazuha replied, "I don't understand what it means either, but those fragments all seem to be part of a treasure."

Heiji asked in surprise, "What treasure?"

Kazuha replied, "It's true. That's what they both said. They also said it was a great treasure left behind by one person."

Heiji asked curiously, "A huge treasure? You didn't exaggerate what they said, did you?"

Kazuha was about to speak.

Conan shouted, "Heiji-nii, look! There's something sparkly on the inside of this fragment!"

Heiji walked over, squatted down, looked at the fragments, and said, "Could this be gold?"

Conan nodded and said, "Yes, just looking at this, you can't tell what kind of amazing treasure it is."

Heiji also complained, "What's going on? This case is really baffling."

Conan muttered, "Besides the fact that Mr. Kato left the group and went to the roof of the castle tower, which is puzzling, the fact that he suddenly started a fire is also very strange. The biggest problem is..."

Heiji continued, "The umbrella that Mr. Kato held tightly before he died."

Conan said, "An umbrella can be associated with rain."

Heiji added, "The rain reminds me of the Dragon and Tiger Stones of Osaka Castle."

Conan asked in confusion, "Dragon Tiger Stone, what is that?"

Heiji asked curiously, "Don't you know? On either side of the Sakura Gate of Osaka Castle, there are two large stones guarding the castle tower, called the Dragon and Tiger Stones. It is said that when it rains, the patterns of a dragon and a tiger will appear on those two stones."

As he was speaking, he suddenly remembered something.

Heiji and Conan said in unison, "Rain?"

The two of them rushed to Officer Da Long's side.

Officer Dairyu and Mori are looking at the scroll.

Heiji stepped forward, snatched the scroll, and said, "Let me see."

Then he took the scroll out into the rain and let the rain fall on it.

Officer Dairyu exclaimed in surprise, "Heiji, that's evidence! We can't damage it!"

However, at this time...

Heiji was in no mood to listen to what he had to say.

Ai, watching from the side, asked, "Is it really a treasure?"

Zhiyong nodded and said, "I've heard this legend. It's said that Toyotomi Hideyoshi left behind a great treasure, but whether it's true or not is unknown. However, judging from the current situation, it should be true. But whether the treasure still exists now is hard to say."

He still remembers most of the treasures in the Conan world, even if he can't remember exactly where they are, he knows a little about them.

Toyotomi Hideyoshi was such a famous person.

If he really did leave behind a treasure.

Zhiyong will definitely remember it.

However, he didn't remember this part of the story, so either the treasure was fake, or it had already been taken by someone else.

That's why he didn't remember.

at this time.

The scroll was rained on, and sure enough, the text and images appeared.

Heiji also smiled.

He smiled and said, "Perhaps that legend might actually be true."

Conan nodded and said, "Yes, so somewhere here, there is still Toyotomi Hideyoshi's treasure, the Golden King's treasure."

Heiji also said, "And this treasure should be hidden somewhere in Osaka Castle."

Because Heiji didn't lower his voice, everyone around him heard him.

The four people in the tour group, in particular, all looked at Heiji with strange expressions after hearing what he said.

"What? You already know what that treasure is?"

After listening to what Heiji said.

This greatly surprised Mori.

Officer Dairyu exclaimed in surprise, "Really? Heiji?"

Heiji nodded and said, "Yes, I have to thank Mr. Kato for this fragment that allowed me to deduce it. You can see that there are traces of gold powder on the inside of this fragment."

Officer Da Long took it and looked at it, saying, "It's true."

Mori asked doubtfully, "But this can't really be considered a great treasure, can it?"

Heiji then handed over the scroll and said, "Now, put this scroll with Mr. Kato's eyes and make some connections."

Mori asked in confusion, "A scroll? But apart from the word 'dragon' in the upper right corner, there's nothing else."

As he spoke, he took the scroll back.

But when Mori opened the scroll, he was quite surprised.

“This…this is…”

Heiji explained, "I've heard of this before. After the artist finished the painting, he put multiple layers of paper on top of it before mounting it. So, like the Dragon and Tiger Stones of Osaka Castle, the inscription on the scroll only becomes visible when it gets wet."

Officer Da Long said regretfully, "It's a real shame that the most important words were all burned, so we can't understand them at all."

Mori also said, "Yes, and what is that pattern on the left?"

……

Chapter 539 The Technique of Ignition

After listening to what Mori said.

Xiaolan replied, "Could that pattern be a gourd?"

Kazuha also said, "As far as I know, the gourd was a mark used by Toyotomi Hideyoshi in battle."

Xiao Lan added, "Could that fragment from earlier be a gourd-shaped piece of pottery?"

Kazuha also said, "Could it be that it's filled with gold inside?"

Mori asked doubtfully, "Judging from the dimensions marked on the picture, this gourd is only about 30 centimeters long. Even if it were filled with gold, it wouldn't be worth much money."

Zhiyong smiled and said, "One gourd isn't worth much, but what if there were a thousand?"

Mori asked in confusion, "A thousand?"

Zhiyong explained, "For every battle that Toyotomi Hideyoshi won, he would add a gourd, which is called the Thousand-Layer Gourd."

Officer Da Long said in surprise, "Could it be...?"

Heiji chimed in, "That's right. If there were a thousand of these gourds, it would be a huge treasure. Add to that its historical value, and it would be priceless."

Zhiyong also said, "So, thirteen years ago, and not long ago, along with Mr. Kato, all three of them had such fragments on them. This means that all three of them were searching for this treasure, but they were killed by their accomplices or others who wanted to keep it all for themselves."

Officer Da Long asked in confusion, "That's strange. The chief and Team Leader Yuanshan only saw two fragments, how did they know that it was related to a treasure? The scroll shouldn't have been discovered yet at that time."

Kazuha explained, "This must be deduced from the shape. The piece my dad took out looks like the opening of a gourd, and it even has the number 848 written on it."

Katagiri Maho nodded and said, "Eight hundred and forty-eight is within the range of one thousand, so it's not a problem to think of it that way."

Kasuya Hiroya also said, "Yes, if those two fragments also have gold dust on them, it's perfectly normal to think that way."

Fukushima Toshiaki also said, "If it is Toyotomi Hideyoshi's treasure, it might be true. It is said that after Toyotomi Hideyoshi died, the treasure piled up in Osaka Castle left Tokugawa Ieyasu dumbfounded."

Shigehiko Wakisaka also said, "Yes, Toyotomi Hideyoshi put a lot of gold into the Kinmei Well in front of Osaka Castle in order to make the water in the well purer."

Mori asked doubtfully, "But even if all of this is true, how could this scroll be related to the treasure?"

Heiji said, "Please, he stored gold in the pottery and added several layers of paper to the scroll to hide this secret. The scroll has the character 'dragon' written on it, which means..."

"There's also a scroll with the character 'tiger' on it."

A voice came from behind them.

When everyone turned around, they realized that the person who had come was Kazuha's father, Ginjiro Toyama, the head of the criminal investigation department of the Osaka Prefectural Police Headquarters.

Standing next to Ginjiro Toyama was Kazuha; it must have been Kazuha who had called her father over.

Ginjiro Toyama continued, "Since this scroll with the character 'Dragon' can reveal its pattern after being rained on, just like the Dragon-Tiger Stone, it means there should also be a scroll with the character 'Tiger.' And the scroll with the character 'Tiger' might very well contain the location of the treasure. Am I right, Heiji?"

Officer Da Long asked in confusion, "Team Leader Yuanshan, what brings you here?"

Kazuha said, "I called him here. Anyway, it's not far from the Osaka Prefectural Police Station. Besides, my dad has been investigating this case. If we don't find someone to take over, Heiji will be buried in the case and won't be able to hang out with us."

Ginjiro Toyama smiled and said, "Kazuha is right, leave this to us."

Kazuha smiled and said, "That's right, that's right. There's a great restaurant near Shinbashi in Osaka Castle. Let's go eat there now."

Heiji retorted angrily, "What are you talking about? A murder has just happened right in front of me, how can I leisurely go out to eat?"

As he spoke, he noticed Ginjiro Toyama's sharp gaze, so his tone softened considerably.

Heiji said kindly, "In my opinion, you don't need to worry about me. You and Ran should go eat."
