After Hattori Heiji finished speaking excitedly, he suddenly realized one thing, and he was immediately very embarrassed.

He cleared his throat, lowered his hand, and walked on as if nothing had happened.

- Although Shiraishi uses the word "maybe".

But in Hattori's opinion, if Shiraishi really can't be sure that the treasure is related to the old lady, then he will definitely not just say the answer. Instead, he will explain the reasoning process from the beginning, just like other detectives, so that his companions can help him see which part of the reasoning is problematic.

However, Shiraishi directly said the conclusion.

…… This shows that in his mind, the answer to this question is very obvious, and it doesn't even need to be explained too much.

But it took me a few minutes to figure it out, and I accidentally said it...... It's too embarrassing for the Osaka detective!

Hattori Heiji was unwilling.

After a second, he suddenly felt even more embarrassed - Shiraishi didn't know what he was thinking, and he could have pretended that he would say, "I see", because he had solved other mysteries.

So Hattori Heiji immediately put his face back on it. At the same time, I was glad that it was very dark here, and Shiraishi couldn't see his expression clearly.

Shiraishi actually saw it clearly.

However, he is not very interested in the process of repairing the self-esteem of high school students, only that this teammate has finally figured out the situation, and when the police come, he can be a qualified commentator.

Other than that...... It's almost time to send information to the old lady.

Shiraishi followed the guidance of the ghosts, taking advantage of Hattori's mood fluctuations, and inadvertently took him to the exit, intending to have a wonderful chance encounter.

The two soon came to the end of a road.

Hattori Heiji looked around, and stopped by himself without any deliberate reminder from Shiraishi - judging by the terrain, it was very likely that this place would be connected to the corridor of the castle.

Thinking so, Hattori Heiji plans to knock on the wall first to see if the back is hollow or solid, and if it is hollow, he can look for the mechanism with confidence.

However, as soon as he lifted the folding stick, before he could knock it out, he suddenly saw Shiraishi approaching the door, looking for something carefully, but unfortunately blocked the landing point of his stick.

Hattori Heiji thought to himself, sure enough, the hero saw the same thing, that is, it was easy for Shiraishi to do white work.

He reversed the direction of the folding stick in his hand and continued to knock it where it was not blocked by the white stone.

If it's empty, look for the trap with Shiraishi.

If it is solid, it is equivalent to directly ruling out a wrong answer.

But Shiraishi found the switch faster than he knocked on the wall.

- Before the stick landed on the wall, Hattori Heiji saw Shiraishi raise his hand and press it against the wall, and immediately after, the wall in front of him suddenly flipped and opened.

Outside, sure enough, was the hallway of the castle.

But to Hattori's surprise, there was a man standing in the hallway. The man turned his head in horror and made eye contact with them.

- The "old lady" has gray hair that hangs down to her waist, her face is pitted and wrinkled, and she wears an old-fashioned hat on her head, but her appearance has not changed.

But she should have been disabled, but at this time she did not have a wheelchair by her side, she stood firm on her own, and her figure was obviously much taller than before.

Hattori was stunned when he saw it, and secretly thought that his luck was really good today, and he wanted to come to whatever he wanted - just as he was about to find the "old lady" to inquire about the situation, she sent it to the door by herself.

And in this way, it can be completely determined - the real old lady has long been unable to walk due to leg disease, but the person in front of her is standing so steadily, he must be an impostor! Reading the Library

The revolving door is now exactly 90° to the wall.

Hattori reacted very quickly, and swooped out from the side where there was no Shiraishi.

Nishikawa shuddered and turned her head and ran to the other wall, trying to trigger the mechanism to hide in the secret passage, but before that, Hattori pounced and firmly knocked the person down from behind.

"......," Shiraishi sighed as he looked at it. Too weak, this childhood shadow is really too weak, obviously out of proportion to her terrible looks.

In the original plot, she can be so scary, probably all thanks to the juvenile detective team...... Now it's suddenly changed.,Even if Mao Lilan has been put away by himself.,Just the Hattori is one by one.,It's not a violent clearance in seconds.。

However, as a good employee with only a task in mind, Shiraishi has not forgotten his mission to maintain balance.

As soon as Hattori Heiji held the person down, Shiraishi followed very consciously, and said anxiously: "Where's Conan?" ”

“！！” Hattori put a finger to his lips in his busy schedule, and secretly gave Shiraishi a code.

His temporary teammates looked at him, understood for a moment, and stopped talking.

However, Nishikawa has managed to get something.

She rolled her eyes, laughed sinisterly twice, and began to make something out of nothing: "I let my companion watch him, once I lose contact, he will be torn off immediately!" ”

"Calm down, don't mess around." Shiraishi negotiated with her with a sincere face, "We can tell you where the treasure of the castle is hidden, but on the condition that you release the people first." ”

"......" Hattori Heiji sighed in his heart.

Now, in fact, it is not certain that Kudo was arrested by this old lady.

Maybe Conan also discovered the strange traces in the secret passage, and then in order to find out the truth, he indulged in solving the mystery, and put aside his companions' lingering in the secret passages - this kind of thing, Kudo completely did.

There is another possibility.

- Judging from the two trap doors that he and Shiraishi have come into contact with, the position of the secret passage switch is usually set relatively high.

Without anything to put on his feet, Conan couldn't reach the trap at all, so he would be trapped in the tunnels and difficult to get out.

So originally, Hattori Heiji wanted to try around the bush first.

If Conan is really in the hands of this fake old man, then continue to test whether she has accomplices, and if so, how do the two communicate and connect, so that they may be able to take advantage of the time difference to rescue Conan.

If all of the above is the worst-case answer, then it will be too late to negotiate with her.

And if the old lady hadn't seen Conan at all, things would have been easier - catch her and her accomplices together, and ask Mamiya Mitsuru to help send some people to find someone in the secret passage.

Who knew that the abacus was played well, but before he could speak, his teammates directly threw out the hole cards.

In this way, regardless of whether Conan is in the hands of the fake old man or not, she will use this as a bargaining chip for the transaction, because it is difficult to verify on her side.

…… Alas, Kudo is right, if the character is too good, sometimes it can be an obstacle - not enough dogs, and it is easy to lose composure because of the fear of his companions.

Heiji Hattori has a mixed mood.

But now, I can only do what the old lady said.

Seeing that Hattori Heiji let go of the hand holding her, Nishikawa suddenly secretly breathed a sigh of relief and got up from the ground.

She didn't really have any helpers at all.

On the one hand, she didn't want to share the treasure with others, and on the other hand, she also knew that what she was doing was too exaggerated - she had killed so many people, and if the "helper" wanted to sell her, as long as she called the police, she would probably be in prison for a real old lady, and maybe even sentenced to death.
