Conan was stunned.

Felines and canines can communicate with humans simply, but they cannot master human language, and can only respond to certain commands after training, as is the case in popular science magazines.

So what's going on with these two creatures in front of you!

Is it that he has been specially trained to nod his head in agreement after others have finished speaking?

Such a frenzied thing...... It's really in line with the style of "black cat".

Conan thought that he was caught by inexplicably and used to work for the day, which was miserable enough, but he didn't expect that even animals under the black cat would be forced to obey.

In order to verify this speculation, Conan tentatively said something that was obviously wrong: "But I prefer that the pattern is just an anti-counterfeiting mark printed on the bottom of the object by the manufacturer." ”

He stared at the two ordinary-looking animals in front of him, but this time, neither of them nodded.

The fox stared at him in shock for a moment, and then suddenly sighed very humanly.

Then it stretched out its paws, pulled Conan's notebook behind him, and smoothed the pen again, skillfully holding it with its mouth, turning its back to Conan, and reading the words on the paper with the black cat, like two scholars who abandoned the scum and communicated with each other to do problems.

"......" Conan jumped twice out of the corner of his eye. It's not scientific!

When you go back, you should write a letter to the editorial department of the popular science column, and ask them to re-examine whether the animals can understand human speech, and it is best to publish reliable experimental data together!

……

No matter how the worldview is impacted, the mystery that needs to be solved still needs to be solved.

Conan cheekily took his pen back and began to speculate on the kana represented by each symbol based on the information he found in the living room, as well as the Japanese writing habits.

After a short while, the notebook listed the complete password list, and the passwords on various objects were also deciphered.

At the bottom of the plate is "Please look at the vase", and under the vase is "Please look at the candlestick...... After searching around, Conan finally picked up a French dictionary that read, "Please look at the fireplace".

Conan climbed into the fireplace, turned on the flashlight on his watch, and finally found a code pattern in the corner, which he immediately compared and deciphered, but the words that came out of it were:

“…… Please look at the plate. ”

Back to the starting point, the objects are connected in a circle, and there is no final point at all.

Conan looked like he had been pounced on with cold water, his expression was restrained, and he subconsciously glanced at the fox: "Wrong?" ”

The fox didn't know what the problem was, so he tilted his head innocently and looked at him, looking like he couldn't understand human words.

"......" Conan's pen creaked, and his temples jumped twice.

Shiraishi looked away from the fireplace and looked back at the living room.

He remembered that there was nothing wrong with the password reading, and he remembered that it didn't seem to be a sorting problem, but a connecting question.

Connect several items in order to find the mechanism.

Shiraishi looked at the pile of objects with coded words on them, and couldn't remember exactly where they had been placed.

But the living room is so big, and a few things are placed in a mess, as long as you remember the keyword "wire", the rest is very simple.

He raised his head, looked at the chandelier at the top of the living room, and after visually inspecting the position of the table and chairs, he ran all the way up, jumped in the air, and hooked his claws on the lamp.

The moment he hugged the chandelier and forked, Shiraishi keenly felt that the lamp seemed to be dragged down a little by it.

At the same time, the enhanced hearing in this form made Shiraishi faintly hear the sound of the machine turning, but the movement was not obvious.

…… Is the cat too light to trigger the switch?

He was about to instruct the fox to make Conan look away and change himself to a humanoid toggle switch, but at this time, Conan also noticed that the cat was gone, and when he looked up and saw it hanging on the lamp, he was also startled.

His first reaction was that the black cat had climbed to a high place again and couldn't get down.

But soon, recalling what happened at the diplomat's house, Conan felt that it was not so simple - how could this cat be a ghost and a ghost, how could he climb on the lamp for no reason.

Even a fox can understand the password, and there is no reason why the black cat from the code name "Black Cat" is just an ordinary cat.

Is there a problem with the electric light?

Conan pondered for a moment, pushed a table hard, lifted a chair and placed it on it, and climbed up to take a closer look.

Soon, he found a very inconspicuous groove in the base of the lamp.

Having a groove often means being able to pull up and down...... No wonder the cat suddenly wants to hang itself on the lamp!

Conan stood on tiptoe and grabbed the chandelier and pulled it down hard.

He weighed much more than a cat, and after pulling in ten centimeters, he suddenly heard a loud bang, and something heavy seemed to fall from the upper floor.

The ceiling shook twice, and Conan looked up in shock, judging the situation.

Before he could guess anything, the black cat stepped on him all the way to the ground and trotted to the second floor.

Conan hurried to follow.

……

From the outside, this villa has only two floors.

However, after arriving at the corresponding room on the second floor, Conan unexpectedly saw a staircase - this staircase was originally hidden in the ceiling, but now that the mechanism is activated, it is completely revealed.

Shiraishi looked up and saw a head poking down from the top of the stairs.

The old soul with unkempt hair sighed faintly, looking very relieved, but there were tears in the corners of his eyes, I don't know if he regretted that he had set the password too complicated.

Shiraishi retracted his gaze and glanced at the light screen, the task was not yet completed, and he didn't know how to end it.

When he came back to his senses, he saw that Conan had climbed up the stairs, and Shiraishi had followed.

This hidden staircase leads to the attic.

From the outside, the villa is only two floors, but its roof, with a gently sloping spire, gives it a little more space.

It was dark in the attic, but Conan soon saw a leaking window, and he walked over and pushed it open with all his might, and the resistance was not small, and the creeper outside was about to block the window.

After opening the window, the room finally brightened up a little.

There were a lot of painting utensils scattered on the floor of the attic, and Conan was looking down when he suddenly heard something behind him with a frightened "Squeak!" "Yes.

He turned around vigilantly and saw the fox staring at the desk, and his frightened fur exploded.

It rolled back in a panic, squeezing the black cat, the tip of the black cat's ears moved, looked down at the dirt on its body, and slapped it to the side with a claw.

Conan hurriedly picked up the miserable fox and patted it twice soothingly, and by the way, he rua a few handfuls of hair.

He straightened up and looked over at his desk, where he saw a skeleton lying on it, with its hair and clothes still there.

After letting go of the fox and looking at the letter on the table and the posture of the corpse, Conan judged that the man should have died suddenly.

It's just that the content on the letter paper is interesting, and one of them is impressive:

I don't want to give this artwork to Tsuneaki Okuda!
