Conan was stunned.

The cat family and the canine family can communicate with humans in a simple way, but it is impossible to master human language. They can only respond to some specific instructions after training. This is what is written in the popular science magazine.

So what happened to the two creatures above!

Could it be that you have been specially trained to nod and agree after someone else finished speaking?

Such a crazy thing...it's really in line with the style of "Black Cat".

Conan thought that he was being arrested for nothing and was miserable enough to do nothing, but he didn't expect that even the black cat's subordinates would be forced to obey the animals.

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

He stared at the two ordinary animals in front of him, but this time, no one nodded.

The fox looked at him with a shocked look on his face, and suddenly sighed in a humanized manner.

Then it stretched out its claws, pulled Conan's notebook behind it, and then smoothed the pen over, skillfully held it with its mouth, turned its back to Conan, and looked at the words on the paper with the black cat, as if it was not a bad person.

"..." Conan's eyes twitched twice. This is unscientific!

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

...

No matter what impact the worldview is affected, the mystery that should be solved still needs to be solved.

Conan shamelessly asked the pen back and began to speculate on the kana represented by each symbol based on the known information found in the living room and the Japanese writing habits.

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

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

Conan crawled into the fireplace, pressed the flashlight on his watch, and finally found a string of password patterns in the corner. He immediately interpreted it, but the explanation was:

“…Please look at the plate.”

Back to the starting point, the group of items formed a circle, without the final point.

Conan seemed to be thrown into cold water, his expression was restrained, and he subconsciously glanced at the fox: "Did you solve the problem?"

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

"..." The pen in Conan's hand creaked and his temple jumped twice.

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

He remembered that there was no error in the interpretation of the password, and he also remembered that it seemed that it was not a sorting question, but a connected question.

By connecting the placement order of several items in order, you can find the mechanism.

Shiraishi looked at the pile of objects with passwords and did not remember exactly where they were placed.

But the living room is so big, and a few things are placed in a mess. As long as you remember the keyword "connection", the rest will be very simple. The intersection point is 80% in the center of the room.

He raised his head and looked at the chandelier at the top of the living room. After visually measuring the position of the table and chairs, he helped him run higher and higher, jumped up in the air, and raised his claws to hook the light.

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

At the same time, the enhanced hearing in this form made Shiraishi vaguely hear the sound of the rotating clumps, but the movement was not obvious.

...The cat is too light to trigger the switch?

Just as he was about to direct the fox to let Conan turn his sight away, he changed to a human-shaped toggle switch, but at this time, Conan also found that the cat was missing. When he looked up, he was shocked to see it hanging on the light.

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

But soon, after recalling what happened at the diplomat's house, Conan felt that it was not that simple, so how could this cat ghost spirit climb up the lamp for no reason?

Even foxes can understand the password. There is no reason why the black cat, whose code name is "Black Cat", is just an ordinary cat.

Is there something wrong with the light?

Conan thought for a moment, pushed a table hard, then lifted the chair and placed it on it, climbed up and checked it carefully.

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

If there are grooves, it often means that you can pull up and down... No wonder the cat suddenly hangs itself on the light!

Conan stood on tiptoe and pulled the chandelier down.

His weight was much heavier than that of a cat. After pulling it into ten centimeters, he suddenly heard a loud bang, and something heavy fell down from the building.

The ceiling was shaken twice, and Conan looked up at the top in shock, judging the situation.

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

Conan quickly followed.

...

From the outside, this villa has only two floors.

However, after coming to the corresponding room on the second floor, Conan actually saw a staircase. The staircase was originally hidden in the ceiling. Now that the mechanism is activated, it is completely revealed.

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

The old soul with messy hair sighed quietly, looking very relieved, but tears were on the corners of his eyes. I wonder if he regretted that he set the password too complicated.

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

After coming back to his senses, he saw that Conan had climbed up the stairs, and Shiraishi followed him.

This hidden staircase leads to the attic.

From the outside, the villa has only two floors, but its roof is a steeple with a gentle slope, so there is so much space.

The attic was very dark, but Conan soon saw a leaking window. He walked over and pushed it open. The process was quite resistant. The ivy outside was about to block all the windows.

After opening the window, the room finally became a little brighter.

There were many painting tools scattered on the ground of the attic. Conan was looking down at him when he suddenly heard something behind him, "Squeak!" in a panic.

He turned around vigilantly and saw the fox staring at the desk, which was so scared that he burst into tears.

It fell back in panic and got up and squeezed hard on the black cat. The black cat's ears moved, looked down at the dirt stained on its body, and made it stick to the side with a slap.

Conan hurriedly picked up the miserable fox, patted it with comforting twice, and then ruled a few handfuls of hair.

He stood up and looked at the desk, and found a skeleton lying on it, with the skeleton's hair and clothes still there.

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

But the content on the letter paper is very interesting, and one sentence is:
Chapter completed!
