Find the entrance, and the rest is simple.

The structure of the underground palace here is not complicated, even forks in the road are rare, and there are not many twists and turns along the way.

Shiraishi counted the time, and after walking for a few minutes, asked the Q version assistant to speed up the search for the entrance to the dungeon on the side of the protagonist group.

The Q assistant received the message and looked up at the people in front of him.

The group had almost forgotten what they were here for, but luckily there was a puzzle-solving Conan who helped them remember.

Conan first asked if there was a basement or secret room.

After receiving a negative reply, he asked the deacon to take them to his great-grandfather's study.

The study also looks very ordinary. Conan stared at the various murals or ornaments, and even tried to turn the overhead lamp, but he still found nothing.

The Q assistant pondered how to prompt it.

After a moment, it stared at the long hairs on the tip of the black cat's tail and thought about it.

Conan jumped down from the stool and saw the black cat squatting not far from him, the tip of its tail shaking very slightly.

The cat had been glued to Maolilan before, and he didn't bother to walk on his own, but now it suddenly ran down to the ground and stayed in one place for a long time...... Conan always felt that something was not right.

When he looked closer, he realized that the tip of the cat's tail was not moving on its own, but only the cat's hair.

Conan looked at it for two seconds, as if a lightning bolt had struck in his head, and he understood, there was wind in the cracks in the floor.

Other words...... This may be empty underneath.

Conan subconsciously wanted to catch the cat's tail and see if it was the only one with wind or somewhere else.

However, before he could touch it, he was slapped head-on.

He withdrew his hand, and had to lie on the ground himself, testing the direction of the wind.

Soon, Conan found a grip near the wall.

He grabbed the handle and lifted it up, pulling up a wooden floor more than a meter wide, revealing a door under the floor, and a cipher disk above the door, all covered in Russian letters.

A group of people all came together, using common names, birthdays, etc. as passwords, and tried them all out.

The codegate was unresponsive.

Fortunately, Kasaka Natsumi's great-grandfather was more merciful, and he didn't set the limit of permanent locking after a few mistakes, and let them try casually.

Later, he relied on a word that Natsumi Kasaka occasionally heard when she was a child to unlock the code disk, according to the "Shiratori Police Department" who came with her, this is the Russian version of "The Magician at the End of the Century".

As soon as she switched to Japanese, Natsumi Kasaka understood - this was her great-grandfather's nickname. My great-grandfather once attended the 1900 World Exposition in Paris, where he exhibited amazing Japanese dolls, and later some people called him so.

As a group of people chatted and descended into the secret passage, Shiraishi and Amuro stopped in front of a closed stone door.

Compared to the aisle, the door is ornate and carved with a huge two-headed vulture, the coat of arms of the Romanov emperors, and a warm yellow sun behind the bird's head.

There are no keyholes on this door and no handles.

To be exact, it is more like a mural than a door, except that it has been carved into the shape of a door.

Shiraishi's gaze paused on the crown above the two-headed vulture's head.

He remembered that the sun behind the crown was supposed to be aesthetically pleasing at first glance, but it was actually a hint to crack the mechanism - shining the crown with a certain intensity of light for a period of time would trigger the black technology luminance meter and open the tunnel to the coffin.

With that in mind, Shiraishi moved the pillar of light towards the bird's head on the door.

When Amuro saw this "door", he also guessed that there was a mechanism hidden here.

He was about to take a closer look, but before he could take a full look around, the ground suddenly began to shake, gradually cracking in both sides, and a downward staircase was faintly revealed in the middle.

Amuro took a few steps back, stood firm, and looked up, and saw that the crown illuminated by Matsuda on the stone wall was glowing instead of reflecting.

After he was stunned for a moment, he understood—there might be a luminance meter hidden in the crown. every day

…… But how did Matsuda see it in such a short period of time?

That weird intuition again?

Or had he actually been here, or had he heard about the method from Kidd?

That thief was really good at that.

I don't know where Kidd is now, but if he is waiting in the aisle below, he won't be attacked by them if he just goes in with Matsuda.

Anyway, the previous slide was the same, Matsuda looked at it for a few seconds, and then found the location of the mechanism, and broke the door so neatly.

Even further, he should have looked for the entrance to the castle, but he went around to the side of the castle, and no matter how he looked at it, it seemed that he knew the castle in advance.

Once or twice, it can be explained by coincidence, and this is the third time......

Amuro suddenly felt that he was in a bit of danger.

He thought about it and felt that these two people should not kill people - Matsuda's Schrödinger's conscience aside, if he really killed his partner, it would be difficult for him to explain it to Gin alone.

After all, it's not Belmode per capita, and the average person's partner dies a lot, which will definitely arouse suspicion, and when Tequila died before, Gin had found someone to verify it, and Matsuda would not be unclear about this.

And Amuro feels that he is definitely a very suitable partner - casual teammates paddle, and reports are always written by himself.

Unless Matsuda doesn't plan to work in the Black Organization in the future, or Melo suddenly turns into a field agent, there is no other partner who is more suitable for an undercover agent than himself.

No, even if Melo were to be transferred to the field, he would not be better than him, which can be seen from the fact that Matsuda would rather discharge himself outside than go back to Tokyo for a check-up......

After thinking about it, Amuro quickly calmed down and decided to choose between striking first, counterattacking, running away, and playing dead later, depending on the specific situation, and it would be best to further understand the purpose and style of the organization.

He secretly checked the weapon on his body, and deliberately slowed down two steps, intending to let Matsuda walk ahead of him.

And when Baishi passed by him, he said casually: "I didn't expect you to have a study of photometers." ”

He said so, but Amuro knew in his heart that the brightness meter made by these craftsmen looked no different from ordinary glass jewelry until the irradiation time or light intensity reached the standard......

"No, I'm going to follow it because ......" However, things are not the same as Amuro's script.

He heard Matsuda pause, looked up at the stone wall again, and asked sincerely, "Don't you think the two-headed bird is strange?" ”

“……？”

Just because of this?

Amuro couldn't judge the truth of this sentence for a while, and after a slight pause at his feet, he saw Matsuda walking in front of him, who didn't seem to care too much about the position of the two of them, and didn't look like he was planning to sneak attack.

Amuro came back to his senses, looked behind him, listened carefully, and did not hear the sound of the third person, he hesitated for a moment, but still followed down the stairs.

When you reach the end, you will see a spectacular, egg-shaped round space, where the base is flat and there is a certain arc on all sides.

Amuro quickly swept away with his flashlight, and there was no Kidd as far as his eyes could see, and there weren't many places to hide people.

He breathed a sigh of relief, feeling that he might have been overthinking it just now.

When he retracted his gaze, he saw Matsuda walking straight towards a large rectangular wooden box.

……

Shiraishi looked down at the lock on the coffin, and was about to pry it, when suddenly a flower appeared in front of him, and a translucent thing floated out of the coffin - there was really a hidden grandmother.

However, it may be due to the fact that she died too early, and this grandmother, who is very old, looks quite young.

While Amuro was still grinding at the door, Shiraishi asked in a low voice, "What's the matter?" After speaking, he pointed to the coffin again, "Do you mind if I open it?" ”

My great-grandmother was kind and friendly, and she gave me a decent assignment - she wanted to be buried with her husband.

A few decades ago, it would have been very difficult.

But now, in this world, it's not a big deal - as long as Natsumi Kasaka learns the truth, she'll naturally take care of it.

Grandma Ghost has no opinion on opening the coffin, only saying that the structure of the lock is very fine, and if possible, I hope to preserve the crystallization of this art.
