Conan's colleagues: I dance in the sky

"Yi'er, I brought Officer Akechi! Seriously, Yi'er, what are you going to do??" Maori took Akechi into the 'Day Room'

"Miss Maori, may I ask why you came to me so early?" Akechi said.

"Actually, Officer Akechi can call me Xiaoyi! There is no need for Miss Mouri to call me that!"

"That's great! Xiao Yi!"

"Okay, Officer Akechi, um! I mainly want you to help me go to the Tuxiang Museum today to evacuate the tourists! I don't want anyone to get hurt. That's all!" Yi took out the notice letter,

Put it before the wise.

"This? Is it another explosion?" Akechi was surprised.

"That's right! So, I hope Officer Akechi will help me evacuate the tourists like last time! Is that okay?"

"No problem, this is the responsibility I should take!" Akechi said with firm determination, patting his chest!

"That's good! It's 11:30 now, so now, you can ask Officer Mingzhi to evacuate people!" Yi looked at the clock on the wall.

"Yes, as ordered!" After standing at attention, he rushed out like a wild horse that had escaped the reins.

"So! Next, Yi! What do you want to do?" Kaito asked Yi, who looked thoughtful.

"Um, Conan, you guys! Do you have that detective badge? The one that can make calls!" Yi looked at Conan.

Conan suddenly felt embarrassed and his face turned a little red, "Well, yes, yes! But I only have one! The other four are with Haiyuan and the others!"

"That's it! So, Lan, can you call those children over? By the way, there's also the doctor!" Yi looked at Lan, who had been listening.

"Okay!" After saying that, Lan walked out! Suddenly Yi and the others were the only ones left in the room.

"Tell me, Xiaoyi, what do you want to do!" Hattori, who had been silent at first, finally spoke after seeing the person leaving.

"It's very simple! One word! 'Pin'" Yi said the word calmly.

"'Fight'??" the three people shouted in disbelief.

"That's right! We separated into three teams to look for the bomb! Because the devil didn't clearly tell the location of the bomb! Besides, I've read the information in that library! It says whether it's big or small! If you want to find it,

It would be very difficult to pick up something! So, in those 2 hours, all we had to do was 'fight'! And hold the detective badge to facilitate communication!" Yi seemed to be completely immersed in this game!

After Yi finished saying this, everyone fell silent.

"Xiaoyi, I heard from Xiaolan that you have something to do with us? What is it?" The doctor opened the door, breaking the quiet and trance-like environment.

"Well, um! Xiaoai, Ayumi, Mitsuhiko and Genta, can you lend me your detective badges to my sister?" Yi looked at them with a kind look.

"Of course!" Ayumi was the first to take out the badge, and then everyone took out their badges.

"Great! Doctor, this is for you!" Yi handed a badge to the doctor.

"Huh? I want it too?" The doctor was surprised.

"No, doctor, actually, I'm afraid I won't be able to defuse that bomb, so I'll give you one just in case so you can contact me easily! Haha!"

"That's it! No problem. If you don't understand, be sure to tell me! The doctor will definitely help you!" The doctor happily took it, [Hehe, great, I can still use it.

!Hehe~]

"Then, the rest, Kaito, Hattori, here you go!" The two badges formed a beautiful arc in the air.

"That's it, then, everyone, let's go! It's 12 o'clock! The game has started!" Yi said goodbye to everyone and set off on the road to the game.

----------------------------------In front of the museum----------

--------------------------

"Wow! Xiao Yi, this is too big!" Kaito couldn't help but sigh when he saw the building in front of him.

"Okay, don't waste any more time! Hattori, you go to the data room! Kaito, you go to the video room! Then, Conan and I will go to the library! After we find the bomb, we have to notify each other!" Demarcate the boundaries!

After that! Everyone walked towards their respective places.

------------------------------------- Hattori's side---------

----------------------------------

"Wow! There really isn't anyone there! That police officer named Wise is really efficient!" Looking at the quiet information room.

"Wait a minute! Why do I always feel like there's something strange here? I always feel like there's something wrong with the things here!" After a while, Hattori couldn't tell, "Forget it, the bomb is important now!"

----------------------------------Kaito's side----------

----------------------------------

"Wow! This screen is too big! I heard that there is a very precious gem in this library! I don't know where it is?" Kaito's Kaito Kidd addiction is about to happen again! When he heard that there is a gem,

, just want to steal.

[Oh, forget it, let’s find a bomb quickly! Otherwise Xiaoyi will scold me to death again later!]

------------------------------------Iwa Conan's side---------

--------------------------

"Conan, have you found anything over there?" Yi asked Conan from upstairs.

"No, Sister Yi!" Conan's voice echoed in this empty library.

[Damn it, where is it? I can’t find it anywhere!] Yi kicked the chair next to her angrily.

"Squeak!" A mouse ran out from under the chair.

"Ah~~~~~~~rat!" Yi was frightened to death by the sudden rat, and suddenly fell into a very hidden corner.

"Ah! It hurts so much!" Yi touched the head that was hit by the fall, "It hurts so much!"

"Beep, beep, beep, beep, beep, beep!" A very familiar voice broke through Yi's eardrums.

"It's a bomb! Where is it?" Yi suddenly became quiet so that he could easily hear the source of the sound of the bomb. Suddenly, Yi saw a place [it was in a trash can!]

[Sure enough, here!] "Conan, come up to the second floor!" Yi held the badge and looked at the timer with one and a half hours left.

"Sister Yi, have you noticed it?" Conan rushed up as soon as he heard it.

"Yeah!" Yi carefully opened the black shell with a devil's logo on it.

"Didi!" the communicator rang, "Hey, Xiaoyi? I found a bomb here!" Kaito's voice came from the communicator.

"What? You found it too?" Yi was surprised when he heard that Kaito also found a bomb. [What? Are there two of them?]

"Well, so you also discovered it?" From Yi's tone, Kaito probably knew that Yi also discovered it!

"Well, can you dismantle it? Kaito!"

"Well, it's no problem. Its code is very clear. You don't have to worry about me!"

"Well, that's all!" Yi hung up the communication. [Now, I wonder what's going on with Hattori? 】

"Beep beep beep!" Conan's badge rang, "Worker... Conan, um, I found a bomb here, where are you and Xiao Yi?"

"No way! Have you discovered it too?" When Yi heard what Hattori said, he knew that his guess was right.

"Then you have them over there too!"

"By the way, Hattori, you can take it apart yourself! It shouldn't be difficult for you!"

"Yeah!" After Hattori finished speaking, the communication was cut off.

"Sister Yi, come and take a look!" Conan.

"What?" Yi walked over.

"Look, Sister Yi, this bomb has no wires, only a host is there! But the timer is still counting down!" Conan had just studied this bomb, but found that it was no ordinary bomb.

"Is there a code word?" Yi heard Conan say this, which was strange!

"No! I've searched many times! Still not there, Sister Yi." Conan said firmly.

"I'd better ask the doctor!" The communicator was connected, "Hey, doctor, I'm Xiao Yi!"

"Xiao Yi! How are you doing over there?" Upon hearing that the person coming was Xiao Yi, the doctor quickly asked about the situation.

"Doctor, the situation is not ideal now. Well, we found three bombs at the same time in the dialing place! But the other two were ordinary bombs, but now! Mine is an unusual bomb!

"

"Well, can you tell me about his insides?"

"Okay, there is only one host inside, but there is not a single cable!"

"No way! I thought this bomb only appeared in novels! Could it be true?" The doctor muttered there alone.

"Doctor! What does this mean?"

"Oh, Xiao Yi, that is an answer bomb! I originally thought that would only appear in novels! Who knew! It really appeared!"

"Answer the bomb?"

"Oh, he has a host here, and there is a button in it. As soon as you start it, it will give you a very difficult question to guess, and you only have 10 minutes. And if you get the answer wrong or the time is up,

Even before your timer expires, he will explode!"

"That's it! Doctor, I won't let it explode!"

"But, Xiaoyi, few people can answer that!" The doctor was anxious. So far, no one who can answer the question correctly has appeared. He was afraid that Yi...

"That's it! Doctor!" Before the doctor could finish speaking, he died. [Hui, even if it is difficult, I will answer it correctly.]

"Conan, activate the button!" Yi.

"Yeah!" Conan pressed.

"Now, what is the system of linear equations when λ is geometry? Time, start

!" A mechanical voice floated out from the host!

Yi and Conan were both deep in thought.

Yi and Conan squatted down and answered this question on the ground with the chalk on the table.

[If he asked like that, he might be doing it this way! But if he asked for something real, he would be excluded if he did it like that! So, it should be...] I thought of something and wrote it down.

"Okay! Sister Yi! I'm asking for it!" Conan stood up straight and clapped his hands.

Hearing that Conan had already asked, Yi looked at Conan in surprise [Wow, Kudo, how high is your IQ? You are just a high school student, how can you figure out the most difficult formula for college?? I...

In my previous life, I was a college student and I was outclassed by you!]

"That was actually something that Brother Shinichi taught me before!" Seeing the surprise on Yi's face, Conan told a lie.

[Liar, you are simply a god!!! You can do something so difficult!] Yi looked at the answer written by Conan with a look of inferiority:

x1-x2+x4=2

x1-2x2+x3+4x4=3

Add the two equations to get

2x1-3x2+x3+5x4=5

Because at the same time 2x1-3x2+x3+5x4=λ+2

The left sides of two equations are equal. For the equation to have a solution, the right sides of the equations are also equal.

5=λ+2,λ=3

So when λ=3, the system of equations has a solution

x1-x2+x4=2

x1-2x2+x3+4x4=3

Treat x3 and x4 as known quantities, and shift the terms to get

x1-x2=2-x4

x1-2x2=3-x3-4x4

Subtract the two equations to get

x2=x3+3x4-1

Substituting back into the first equation we get x1=x3+2x4+1

Let x3=s,x4=t, then the general solution of the equation is

x1=s+2t+1

x2=s+3t-1

x3=s

x4=t

"So, the answer is x4=t!" Conan told the answer to the bomb.

"Correct! The bomb detonation device is deactivated!" As soon as the voice came out, the timer stopped.

Finally, the bomb was deactivated! Even Hattori and Kaito were the same. The terrifying day passed like this! What awaits tomorrow is the decisive battle between the devil and Yi and the others!
