The dark space is impossible to see, and the surroundings are unusually quiet. There is no need for sight and hearing, and there is no need for extra energy...... Conan used it all to open his mind.

At first, he kept reviewing the actions of Black Cat and Bourbon in his mind, sometimes feeling that they were very similar to one person, and sometimes he felt that there was a difference.

It was always difficult to come to a conclusion, so Conan had to think about one thing differently - what was wrong with this castle?

Shiraishi won't let a child ...... Let an innocent detective who looks like a child be bricked and tied up, and stay alone at the bottom of the secret passage with a terrifying skeleton.

In other words, the black cat must not have discussed it with Shiraishi, and this time, it was an action planned by him alone.

In this case, the problem of the castle must not be small, and it may even be related to that organization......

In many other things, there are not enough clues, and it is useless to break the head.

But the puzzle of the castle is just around the corner.

Conan hesitated for a moment, deciding to focus on this side for the first time - since the black cat also cares about the castle, maybe he can get more clues after helping him solve it.

Thinking of this, Conan remembered one more thing.

He carefully pressed his head against the wall and touched it at a different angle.

Nowhere did it hurt, and it didn't look like there was a dark wound.

So the blood on the head should have been prepared by the black cat in advance and hidden in the blood bag in the hat.

……… In other words, this blood bag is past the expiration date.

It smells terrible.

However, Conan didn't complain in his heart, after all, it was impossible for the black cat to predict what was happening in the castle, and he couldn't prepare armor for himself in advance.

The hat just now must have been used by the black cat on weekdays, but this time it happened to be encountered, so I lent it to myself first to confuse the enemy.

And sneaking up on the head of the black cat, no matter how you think about it, it's a hellish job, so the blood pack filled in it has not been triggered, and the black cat probably forgot to change it, and the filling will deteriorate, and there is no way to do it......

Sure that his head was fine, Conan began to try to break the rope again, but could not break free.

In the end, he had to lie down on the ground, concentrating on what the chessboard on the lawn represented.

……

Although Hattori Heiji felt that there was something wrong with the castle, he didn't tell anyone.

There are only three teammates in total, and now Kudo, who is the best match for him, has disappeared.

And if he told Maoliran about this, Hattori Heiji felt that it would be of no use other than to make her feel scared and flustered, which would make the situation more troublesome.

As for Shiraishi...... He didn't want to be picked up as a hostage No. 2 when he was asleep, and Hattori Heiji was already very satisfied, and he didn't dare to ask for more.

- If at this time, a random child is missing, Hattori Heiji may have run to find Mamiya Mitsuru and ask him to send someone to find him.

But Conan is not a real child, and there is no problem of running away by himself, or being stuck in play.

Most likely, there was some kind of man-made accident that prevented him from moving freely.

The danger, of course, comes from this castle.

Hattori Heiji only dared to ask the helper a little "have you seen Conan", and did not dare to chase after others and even interrogate. qq

- In case Conan discovered some great secret, such as accidentally witnessing the murder scene and being kidnapped by gangsters, the gangsters may not have wanted to kill at first, but they were asked by Hattori Heiji, worried about revealing the stuffing, and the more he thought about it after he went back, the more panicked he became, and he directly tore up Conan's ticket, which is not good.

Therefore, Hattori Heiji secretly used his mobile phone to contact the police officers he knew and asked them to send someone to help.

Until then, he could only hold the folding stick that Shiraishi gave him, and wandered around silently alone, feeling like a lonely walker carrying the cruel truth alone.

……

As a result, when it got dark, Hattori Heiji couldn't find anyone.

He glanced at his phone - maybe unlucky things like to pile up, and the Otaki police department replied to him that the police had encountered heavy rain on the way to arrive, and the road had been washed down, and it might not be until the early hours of the morning.

At this time, a domestic servant found him and told him that he had opened his meal.

Heiji Hattori was indeed hungry.

He went to the restaurant, where he met Maoriran and Shiraishi, who had woken up and was about to have dinner.

Maoliran looked around Hattori and was a little puzzled: "Isn't Conan with you?" ”

“…… He's still solving puzzles, and the kids don't even count. Hattori looked at the table and wanted to find some portable food, "You guys eat, don't worry about me, I also want to continue looking for clues." ”

Maolilan is still not very reassured.

She didn't have much contact with Hattori Heiji, but in just a few days, she also saw that Hattori Heiji could indeed solve the case, but the ability to take care of the child was about 0.

He was with Conan, Conan didn't have an accident, and it was all up to Conan to be sensible.

So after Heiji Hattori left with the bread, the more Moriran thought about it, the more uneasy he became.

She took a few casual bites, wiped her mouth, and got up to check on the situation.

Of course, Mamiya Mitsuru didn't show any displeasure, although it was a waste of the meal he had people prepare, but the tool man was willing to work diligently to find clues, and he would only be happier.

Mao Lilan said that he was looking for someone, but when he reached a fork in the road, he remembered that he had forgotten to ask the two men where they were hiding to solve the mystery.

She took out her mobile phone and wanted to send a message to Hattori Heiji to ask, but before she could click on the message interface, her ankle suddenly cooled, and it hurt vaguely.

Mao Lilan dodged suspiciously, and lowered his head to take a look at the situation, but before he could go down, the whole person was already dizzy and fell headlong.

Shiraishi catches her from behind, knocks the person into the Poké Ball, and then hides the Poké Ball in the corner, removing the mask and returning to the main body.

After that, he politely said goodbye from the table and went into the hallway to pick up the Poké Ball and put it away.

Then I'm going to go to Hattori Heiji, explore the clues with him, and find another opportunity by the way, so that Hattori Heiji "is very unwilling to be forced by you" to tell Nishikawa Minami the clues.

And hiding Maolilan in the ball can effectively prevent herself and Hattori from being attacked by the "old lady" when she is in the underground secret passage.

Although Maolilan's force value is very high, she is particularly afraid of ghosts and has little courage.

Nishikawa didn't know this, but when she attacked Conan in the secret passage just now, Shiraishi carefully observed for a while, and felt that Nishikawa Sami's gloomy expression was more terrifying than a ghost at first glance, maybe she could suppress Maoliran's force to 1%, in that case, Maolilan would undoubtedly be very dangerous.

And if Mao Lilan bottoms out with the help of the protagonist's aura and kicks people to the ground, it will be a bit troublesome...... In short, it's safest to put her away first.

Shiraishi quickly followed the locator and found Hattori Heiji.

Heiji Hattori was standing in the room they had used to observe the chessboard, where Conan had disappeared.
