Conan: The Mechanic

"There's actually a wall in front of you," Officer Shiratori shone a flashlight in front of him, and glanced at Chiba as he spoke. "Little guy, your eyes are really good. I didn't see anything at the same distance just now."

"No, I'm more inclined to be wrong now..." Qian Yu said embarrassingly. "I only actually saw this wall half a minute ago. Before that, it was only at that time that I had that feeling, thinking that I had just seen something. Now I think about it, it may be an illusion or something. If If I really see it clearly, some feedback about the wall should have flashed in my mind just now."

A wall with many decorations appeared in front of them - to be precise, the center of the wall was a whole piece of wall painted in gold, as if it was going to be used as a background cloth, and a lot of decorations were dotted on the wall. on this background cloth. Qianyu counted it, and there were two blue, five red and seven solid-color diagonal lines, and the upper sides of each diagonal line were more or less embellished.

On the upper left corner of the background cloth are two eight-pointed star badges that are close to each other, of different sizes, but of the same shape. From top to bottom, it is dotted with a blue-circled double-headed eagle and a gold cross on a black background.

On the upper right of the background cloth is a red diagonal line, next to it is a gold cross dotted with red circles.

In the center of the background cloth is the same blue slash, but there is only an eight-pointed star on the side, with a blue-circled double-headed eagle on it.

On the left and right of this blue slash, there are two other red slashes. Although these four slashes have different heights, they are the same as the red slashes in the upper right corner. There is an octagonal star decorated with a red circle and a gold cross. accompany.

[And besides that...]

Using the flashlight's diffused light, Chiba looked a little further down the wall.

In the lower middle of the background cloth, there is also a solitary decoration - a blue-circled double-headed eagle without a diagonal line - that is one that makes everyone who sees it wonder why it was placed there. Strange existence.

"This wall looks very strange, it may be something like an institution," Police Officer Shiratori said in a rather sincere tone as his eyes swept over Chiba, Conan and Mouri. "I don't know if you have any good ideas."

After a suffocating silence, Kogoro Mouri spoke unwillingly.

"In principle, I think the patterns themselves are tricky," he said, staring at the patterns. "But...I also have to admit that I don't know much about this, and maybe we should focus on another battleground first - whether it's to protect a potential victim me or to figure out what to do next, we We must find Miss Pu Siqinglan and protect her."

If there is really a think tank that can provide them with intellectual assistance, it must be the research expert on the history of the Romanov Dynasty.

But when they are so disheartened and ready to return to seek stronger professional assistance...

"Is this place transparent?" Qianyu raised a small flashlight without warning and aimed it at the solitary blue-circled double-headed eagle. "The other blue circles are embellished with glass fragments, but the embellishment of this double-headed eagle... It doesn't look like that kind of cheap stuff, but closer to the real sapphire?"

"Ah?" Everyone was stunned, but Chiyu didn't care about them, but turned the tip of the flashlight while turning her eyes on Officer Shiratori.

At this moment, Officer Shiratori was looking at the blue circle illuminated by Chiba, with a look of disbelief and disbelief on his face. It wasn't until a few seconds later that he turned his eyes back to Qianyu, and realized that the other party was staring at him.

Chiyu looked at him with a very subtle expression, which made Officer Shiratori feel a little hairy in her heart. However, just when he couldn't help but want to ask why the other party was staring at him, Qianyu turned his head and looked at the blue circle again - the original light of the flashlight was too broad, and at this time it had been reduced to a fairly narrow circle. Inside. Correspondingly, the light gathered in a narrow area is also brighter than before.

"Boom—" A sound came from behind the wall in front, and it got louder and louder.

No... not just the wall in front...

Chiyu jumped to one side like a frightened cat, and the ground he was standing on split to both sides at about the same time.

[Moses divided the sea], this is the feeling that flashed in Qianyu's mind for a moment.

Undoubtedly, his actions just now triggered the trap, and a secret passageway hidden underground was slowly opening in front of them.

"What's going on?" Fei Yingli stared at the secret passage that slowly appeared in front of them below. "This is... an agency?"

"The light-sensitive mechanism turns on when it receives light. In the early 20th century, there were indeed mechanisms that could sense light energy, but..." Conan adjusted his glasses and walked to the beginning of the stairs. "To be able to maintain a normal state for decades without decay is an astonishing achievement."

Just as they were talking, the activity of the agency ended, and a descending staircase about one meter wide appeared in front of them, and the end point was the gate that appeared at the end of the steps.

"If it's a stone or metal mechanism, this isn't particularly outrageous~www.readwn.com~ but the problem is..." Chiba stood up and walked to Conan's side. "From a certain point of view, an organization of this level cannot be created by a few people."

The ones that were separated to both sides just now were not ordinary thin plates, but super-large solid stones with right-angled trapezoid cross-sections. The volume of each half was at least 10 cubic meters, and the weight was conservatively estimated to be 30 tons. If calculated according to the rolling friction coefficient of the metal wheel and the rail, the power to drive this mechanism requires at least 3000 N of driving force (this is only the minimum theoretical requirement, in fact, considering the more backward quality of the old materials and the long-term loss of the mechanism, 5000 cattle may not be able to complete the drive.)

Then the question is, can such a powerful mechanism system really be secretly completed by Mr. Kasaka Kiichi with a dozen people?

At least according to Chiba's point of view, the installation of such a mechanism absolutely requires the help of professional construction machinery.

In addition, the amount of engineering for this secret passage is also too large - Qianyu and the others have just passed through a spiral tunnel with a length of more than 400 meters, and the width of the section is more than 8 meters and the height is more than 5 meters, which means about 20,000 Quantity of earthwork in cubic meters. Even the most suitable type of soil for construction requires about 30,000 man-hours of manual excavation, which is equivalent to the workload of 10 people excavating for at least a whole year.

Compared with such an unlikely secret excavation theory, another explanation is much more reasonable, and it is also quite feasible.

Kasaka Kiyi asked the professional construction team for help, and asked them to use equipment such as shield machines to complete the construction of this underground secret tunnel.

"Okay, let's go in and have a look." In the end, it was Officer Shiratori's impatient voice that interrupted the discussion between Chiba and Conan.
