Conan: The Mechanic

"That's why." After entering the Ooka family's mansion through the small door on the wall that Iori opened, Chiwa turned her head and watched Iori close the small door and close the latches layer by layer. "How many such organs are there in the mansion?"

Looking at the gate of Ooka Momiji Mansion from the air, you will find that the outer wall and the gate of the mansion are in a concave shape (the inward part is the gate of the mansion, and the two sides are convex walls.) And the small door opened by Iori Right at the right protruding corner: Unlike the door of the mansion facing the outside, this small door is in the middle of the wall on the right after going out, and its hidden position in the depression makes it impossible to force it open from the outside (Author: Because There is not enough room for acceleration.) And with such a natural structural advantage, Oka Mansion arranged layers of latches behind this secret door for reinforcement, completely cutting off the possibility of violent intrusion from the outside world—— If you really want to break open the secret door from here, you might as well choose to climb over the wall and enter.

"A lot. After all, it is the large mansion where the eldest lady lives, and a large number of safety protection facilities must be used to fill the gap of manpower. Thanks to this, the security system of the mansion wall is very complete." Iori was just very I vaguely described it, obviously not wanting to leak too much. "In short, the mansion is absolutely safe, you don't have to worry too much."

After speaking, Iori walked around Chiba and motioned for the three of them to follow him. However, Chiba did not follow directly like Shinichi Heiji, but just looked at Iori's feet.

There is a wooden floor here, but his leather shoes hardly make any noise when stepping on it, completely submerged in the sound of water in the courtyard...

As if to prove how extraordinary this is, I don't realize that too many Shinichi and Heiji's sneakers stepped on the same board that Iori had just stepped on, and the heavy and rude steps brought about it. A gnawing wood moan.

And not only this step, the other two next steps of the two of them also made a harsh noise.

If Chiba expected it well, a circle of wooden boards that were not so strong was specially laid in the courtyard. After the intruder stepped on, the occupants and guards in the mansion would know this and be on guard.

However, how did the housekeeper Iori walk on it?

The auxiliary unit switches to a more targeted mode to extract and strengthen the narrow frequency band where the footsteps exist, and the visual unit also begins to analyze Iori's steps.

When Chiyu's footsteps suddenly became silent, Iori glanced at Chiyu with some strange eyes, but in the end she didn't say anything, just continued to lead them forward.

……

"What a gorgeous and elegant landscape system!" Walking in the courtyard of Ooka's house, Hattori Heiji expressed his surprise. "Although I also know that the Ooka family is very rich, but this..."

As the son of the Chief Inspector, Hattori Heiji certainly wouldn't express such a strong admiration for the general landscape - even the most profound wealthy family in Kyoto is not worthy of being a high-spirited high school detective like him.

But the equipment here is really...

According to what they saw before commuting here, there is no active above-ground water source in this area. However, in this mansion, they saw a large and small ponds connected by a ribbon-like stream of living water.

There is no doubt that there is a very developed water circulation system here, which provides abundant circulating water resources for this waterless land all the time.

But this is not really something worth talking about in this mansion, because Chiba found that the scale of the machines used to drive the water conservancy system here is a bit too large.

This conclusion came from what Chiba saw in a medium-sized building that was not inconspicuous at first, but attracted attention because of its large and somewhat exaggerated chimney.

What's more interesting is that a stream of water gushed out from a drain at the bottom of the building with a ferocious force visible to the naked eye, and after it merged into the mainstream, it drove it to flow slowly and directionally.

There is no doubt that this is the water injection port of the landscape, and...

When the group passed through this tributary, Qianyu, taking advantage of the others' inattentive efforts, secretly bent down and touched the water in this tributary with her fingers.

The temperature is very high, at least 60 degrees. If you are looking for a reasonable explanation, it is probably that the power mechanism has injected its own cooling water here. But if you really want to heat the water to such a degree, the power of this machine is a bit high...

"Pfft—" Accompanied by such a wonderful sound, a dense cloud of white smoke was discharged from the big chimney, and then spread quickly, disappearing into nothingness.

[The search of gas molecules is completed, and the main components match: anthracite] - the auxiliary unit quickly gives fast analysis results

[In other words, is there a set of thermal power generation equipment and related supporting equipment installed here? 】Thinking like this, Chiyu retracted the hand that touched the water stream into her pocket, and continued to follow the others without saying a word.

This wave just now is the third cloud of smoke within 30 seconds. If the normal mechanical efficiency is substituted into the inferred exhaust gas volume per unit time, it can also confirm the conclusion that the power of this machine determined from the water temperature is absolutely not small. ~www.NovelMTL.com~ Maybe there will be more than 90% power redundancy in addition to pushing the landscape water flow they can see, and maybe even all the power consumption that such a courtyard should have (the area of ​​this mansion Although it is large, the buildings are relatively scattered, so the power consumption during the day will not be more than an order of magnitude lower than that of the orange mansion with full lights), which is not enough.

If a machine only needs to do a pitiful job on the bright side, but it runs at extremely high power, and is specially equipped with a large and amazing chimney...

Chiyu finally turned her gaze to the ground.

The most reasonable inference is that the Ooka House is far more than just a few things on the ground. There may be a larger building complex hidden underground, and only a power-consuming unit of this scale is necessary to match such a scale of power generation. system.

Should it be said to be a wealthy family? Even if it's just a seemingly ordinary mansion (of course, ordinary does not mean the area), there are such secrets hidden inside.

Thinking like this, Chiba followed Iori to the largest house in the middle of the courtyard.

Just as they were about to walk there, the door of the house suddenly opened.

Ooka Momiji, who was wearing a high school uniform, appeared from behind the door, but he didn't care about the others, he just stared straight at Hattori Heiji alone.

"..." Chiyu and Kudo Shinichi raised their eyebrows and glanced at each other, but said nothing.

"There are so many people here?" After a while, Ooka Hongye also realized his gaffe and put on a very dignified appearance again. "Um... Heiji, can I make a request?

"I hope that you are the only one who comes to have a one-on-one inquiry with me - don't worry, I will let Iori treat the other two well."
