The investigation into the guard room of Didan Elementary School is progressing very smoothly.

Gao Yuan, who was familiar with the road, used the force of the chain stretched by the "star" to climb into the campus through a tree near the school wall.

Then, after noticing that the guards were already patrolling the school, Gao Yuan took advantage of this opportunity to avoid the few surveillance cameras in the school, entered the guard room, and began to investigate the surveillance——

Soon, Gao Yuan found the monitoring content he needed.

In order to save time, Gao Yuan did not rush to confirm whether there was any problem with the content of the surveillance video. Instead, he simply copied the entire surveillance content to a USB flash drive he carried with him, preparing to take the content back and analyze it slowly.

In this regard, after Gao Yuan used the limited time to do all this, before the guards came back, Gao Yuan left here as soon as possible, followed the way he came, and prepared to return the same way——

However, for some unknown reason, Gao Yuan did not return directly to the location where he entered the campus, but chose to go to the feeding hut on campus.

Gao Yuan has been here before.

That time it was to find the time capsule hidden here by Miyano Akemi.

Now, Gao Yuan came here because he wanted to see with his own eyes the guinea pig that seemed to have become smaller after being fed "aptx4869"——

After all, judging from the current situation, if there is no problem with the surveillance content, then the person who put the letter in Xiao Ai's shoe cabinet should be a member of the organization after his body shrank, and that person's identity is most likely Xiao Ai.

Said Junerik.

But if that's the case, then what's the purpose of giving "aptx4869" to the school's guinea pigs?

According to the current inference, if the prisoner is Junerik, then he should have successfully taken "aptx4869" and his body has transformed into what it was like in childhood.

In that case, is it necessary for him to use drugs on other animals?

Logically speaking, the purpose of using drugs on animals is to test their efficacy, right?

Now that he has successfully turned into a child, is it still necessary to verify the efficacy of the medicine?

Thinking of these, with doubts, Gao Yuan finally came to the breeding hut, took out his mobile phone, and used the flashlight function of the mobile phone to illuminate the situation of the breeding hut, preparing to take a look at the condition of the guinea pig that was said to have shrunk.

——

However, when Gao Yuan carefully observed the guinea pigs in the breeding hut, he didn't feel anything at first glance. But after Gao Yuan took a closer look, he discovered something unusual——

According to Xiao Ai and Conan, the guinea pigs in the school's breeding hut should now have one rat and three mice.

Among them, the fur color of a certain mouse should be snow-white, and one of its ears is half broken. It is suspected that the original mouse father looked like a smaller one.

But now, after Gao Yuan's careful search, Gao Yuan did not find this mouse that was suspected of being fed drugs and became smaller in the breeding hut——

That is to say, Gao Yuan only saw one rat and two mice in the current breeding hut. The strange mouse that should have existed according to Xiao Ai and Conan was missing!

Faced with this situation, Gao Yuan was afraid that he might have made a mistake, so he couldn't help but carefully began to search for traces of the mouse in the breeding hut, and even carefully picked up the rat in the breeding hut with his hands.

I was worried that the rat might have suppressed the mouse.

But in the end, after searching the breeding shed inside and out, Gao Yuan could not find the strange mouse.

Deeply puzzled by this, Gao Yuan did not waste too much time here. Now that he had confirmed that the strange mouse was not in the breeding cabin, he had better go home quickly and analyze the surveillance video first.

So, after Gao Yuan calmed down the three guinea pigs who were startled by him and were trembling a little, he restored the situation in the breeding hut to its original state as much as possible. Gao Yuan turned around and left Didan Elementary School from where he sneaked into the school.

Walking towards my home on foot——

When he returned to Mingzhi's house and saw that Xiao Ai was not staying in the study or living room as usual, Gao Yuan understood that Xiao Ai had indeed hid in the basement out of fear.

So, when he came to the study, Gao Yuan pressed the star-shaped decoration on the "star" from his pocket, thereby opening the passage to the basement, and walked down into the basement called "Tower".

Here, Gao Yuan saw that Xiao Ai was in front of the computer, very focused on searching for something, and didn't even seem to notice Gao Yuan coming in.

Therefore, seeing Xiao Ai's appearance, Gao Yuan did not intend to interrupt her actions, and prepared to go to the next floor and use the main computer to analyze the copied video——

"You didn't encounter any danger!"

However, although Gao Yuan was not prepared to disturb Xiao Ai, Xiao Ai still noticed the fact that Gao Yuan had returned, so with a somewhat anxious tone, Xiao Ai expressed concern to Gao Yuan.

In response, seeing that Xiao Ai had stopped what he was doing, turned around, and looked at him nervously, Gao Yuan answered directly:

"No...everything went well. I brought back the surveillance video. With a little analysis, I should be able to determine the situation."

"Yeah...that's good."

Hearing what Gao Yuan said, Xiao Ai said with a little relief, then turned around and continued to operate something on the computer——

"Then... Haiyuan, what are you doing?"

In this regard, looking at Xiao Ai's serious look, Gao Yuan thought for a while and asked with some concern.

"I was thinking, if the other party is really Junai, how did he find me..."

Xiao Ai also straightforwardly explained to Gao Yuan the operation she was currently performing:

"Junai is aware of the experiments I conducted. If he also conducted experiments on drugs after I left the organization, it is indeed possible that he would have discovered the possibility that the drugs I developed could infantilize organisms.

the existence of sex.

"Therefore, if he guesses that I may have taken that kind of medicine to make my body smaller and escape from the organization, it is entirely possible for him to find photos of my childhood from the organization's database. That possibility

It cannot be said that there is no sex...

"But the problem is..."

"Even if he guessed that you might have shrunk and got a photo of you as a child, how did he finally find Didan Elementary School with this photo?"

Following Xiao Ai's words, Gao Yuan understood what the other party meant, so he answered.

"That's right."

Xiao Ai couldn't help but nodded and said affirmatively:

"Even if he knows that I have become smaller, he cannot determine my current location. Trying to find me is still the same as finding a needle in a haystack. Therefore, since he can now find Didan Elementary School, I am wondering how he used it to find me.

The means to find me..."

In response, Gao Yuan also nodded seriously——

Indeed, this is something Gao Yuan cannot understand now.

--"unless……"

Hearing this, Gao Yuan thought for a moment, and then he couldn't help but think of something——

If the other person has a photo of Xiao Ai, then put yourself in their shoes and put yourself in the other person's shoes. What should you do?

After thinking about it for a while, Gao Yuan soon came up with an idea——

"I'll try……"

Gao Yuan said, stepped forward in front of Xiao Ai, and began to operate the laptop used by Xiao Ai with both hands——

After Gao Yuan first took a photo of Xiao Ai's face through the camera of his laptop, Gao Yuan opened the crawler software, limited the search scope to Tokyo, and started using the crawler software on the Internet using facial recognition.

Start a comparison search.

Then soon, photos on the Internet were searched out through this crawler software——

Although this crawler software's algorithm for searching similar photos using facial recognition is not very mature, almost most of the photos it can search are specious and not photos of Xiao Ai.

But not long after, as a website interface appeared, Gao Yuan and Xiao Ai were stunned——

That is a webpage introducing Didan Elementary School.

On this webpage, there is a photo that appears to have been taken at Didan Elementary School when most of the students were walking out of school together.

As this is a school website, the school seemed to use it to introduce the school atmosphere of Didan Elementary School, so they randomly captured such a moment.

And in this momentary scene, in the corner of the photo, through the recognition of the crawler software, Xiao Ai's figure was actually found in it——

Xiao Ai, who was accompanied by everyone from the Youth Detective Team, just appeared in a photo on the school website!

In this regard, since the other photos found by the crawler software were not of Xiao Ai himself, but just some photos that looked like Xiao Ai's figure, in the end, Gao Yuan and Xiao Ai were able to basically determine the reason for the exposure——

"That Junerik, after knowing that you might become smaller, guessed that you might be hiding in elementary schools, so he checked the web pages of elementary schools across the country, and then found Didan Elementary School!"

Gao Yuan quickly came to the possibility, and Xiao Ai couldn't help but nodded in agreement with a solemn expression.

"He found me after seeing the school's website... I actually knew how to..."

Regarding the current situation, Xiao Ai lowered her head and said with some self-blame. Then she was silent for a while, seemed to have thought of something and forced out a smile:

"But looking at it this way, he probably doesn't know about the existence of you and Edogawa. After all, he came directly to the school, so..."

"It doesn't matter whether you know it or not."

Interrupting Xiao Ai's words, Gao Yuan said seriously:

"No matter what, I won't let you face it alone!"

As he spoke, Gao Yuan's hands quickly started typing on the keyboard, and then he hacked into the backend of Didan Primary School's website through the Internet, and modified the photo of Xiao Ai, directly

Cropped to capture the scene of Xiao Ai——

In this way, the scene exposing Xiao Ai's existence no longer exists on the Internet.

Then, through the website's background access records, Gao Yuan began to analyze the network IP addresses that had visited this page, wondering if he could find traces of "Juneric" from them——

There are not many records of visiting the school website, and the other party may have saved the photo, so it is not too troublesome to find the suspicious IP address.

In any case, Gao Yuan is still very confident in his own technology in cyberspace...
