[Conan Doujin] Let's become smaller together · Part 1

The author has something to say:

⊙▽⊙I'm so stupid, 0~9 are indeed 10 possibilities. Thank you XXXGN~

PM2:54 in front of the basement password door

The police present were all dumbfounded, 20?There are ten possibilities for one person, and there are ten possibilities to the twentieth power for 20 people. How is it possible to try it out! !

"Why do you know it's twenty?" Conan's focus is always different from others, and it will always be the most important point.

"Why... I don't remember..." Ando was also confused, "Do you remember Yuan Taijun?"

"I also remember that it seems to be 20." After all, Yuantai woke up earlier than Ando, ​​and remembered a little more things, "I remember it sounded five times, stopped for a while, and then crackled again. 4 times, so four times five should be 20 times!" For Shin Yi Huisheng, multiplication is already very difficult.

Takagi pondered: "So it's possible that he divided the 20-digit password into four times to memorize it, or it's possible..."

"It's a four-digit password, and there are 4 layers of passwords in total. I already know the password, Yuan Taijun, don't worry, I'm here to save you." Conan lowered his head slightly, and a white light flashed on the lens.The calm, wise and confident detective is back.

"Huh?" Yamato Dasuke and Uehara Yui expressed that it was very difficult for them. At any time, an elementary school student's intelligence can be much higher than these criminal policemen.They just thought that there are ten to twenty powers of possibilities in a 20-digit password, and the little detective directly told them that the password is four digits and has four layers, and they even know the password! !

"Conan-kun, what's going on here?" Yui Uehara, who was not ashamed to ask, surrendered to the little detective in his arms.

Conan, who already knew the answer, seemed unhurried, completely different from the way he was sprinting outside the room just now.

He smiled faintly, then pointed to the portrait on the wall that was ignored by everyone and said, "Don't you think it's strange to have a portrait here?"

portrait?

The detectives looked up, indeed, why is it necessary to put such a large oil painting at such a narrow and dark basement door?This place looks like a secret base at first glance. It is impossible to have guests, even if you appreciate it yourself, wouldn't it be better to put it inside the password door?

"If a painting is hung here for no reason, then there must be a reason for this painting to be hung here." Conan continued, "I just broke the painting and it didn't move at all. So this painting The painting can be said to be inlaid on this wall as a whole. Since it is not hiding anything behind the portrait, then it must be what this painting represents. Combined with the situation here, this painting has only two functions. One: hiding and monitoring monitor, so that the people inside can see what is happening outside. Of course, if you observe carefully, you can see that there is no monitor here. Moreover, the light conditions here are not suitable for installing a monitor. Then there can only be the second possibility— —Auxiliary to remember the password to open the door."

Hearing this, everyone looked up at the oil painting.

With the mysterious universe as the background, the tail needle of the huge black scorpion is raised flamboyantly, and the carapace reflects a sharp luster under the faint starlight.A feathered arrow was shooting towards him.Scorpion tilted his head slightly, causing the arrow to fly past his forehead, and the arrow tail almost pierced his eyes.The traces pierced by the arrows are a giant tree reaching to the sky and a tiny jungle on the ground.

And the blank space in the upper left corner is inscribed with a few lines:
