Ke Xue: Shinichi and I are childhood friends.

After a while, Yuya and Conan came out of the alley.

"It looks like they retreated after hearing the sirens."

The two arrived at the foreigner's body, and Yuu knelt down and began to search the man's body.

"Hey, don't touch it like that, you'll get yelled at by the police," the three passersby who discovered the body kindly reminded Yuya.

Yuya calmly said, "I'm a detective. You guys stay away and be careful not to disturb the scene."

The three then noticed that Yuya's face looked familiar, and immediately recognized him as the famous high school detective. They quickly took a few steps back.

Soon, Yu found an identification card in the man's chest pocket. It was an FBI card with the name Jim Mason on it.

After glancing at the identification, Yuya's expression turned grave: "They're FBI agents."

Conan noticed a light on the man's chest. He wrapped his handkerchief around his hand and pulled out a cell phone from there. It wasn't locked or turned off, and the screen displayed several lines of unintelligible characters.

Yu glanced at it and said, "It's the FBI's secret code, right? But it's too simple. You can tell at a glance."

Conan nodded: "Hmm, this code specifies the meeting place, date, and time. Since Vodka appeared here, did they intercept the code and find out the FBI meeting place?"

Yuya nodded: "Anyway, let's leave this to the police. We'll contact Mr. Akai and ask him what happened."

"If I'm not mistaken, the unidentified foreigners who died earlier were very likely FBI agents as well."

···

The Kudo family.

Yuya and Conan found Shuichi Akai, Jodie, Camel, and some unfamiliar foreigners in the study.

Yuya clicked her tongue in astonishment: "These people can't all be...?"

Judy didn't hide anything: "They were all FBI agents."

Yu was somewhat speechless. Didn't the FBI have its own bases? Why did they have to come to the Kudo family's house? Were they afraid of not being discovered?

However, he didn't show it, but instead asked with feigned confusion, "So, why are you all gathered here?"

James pulled him over and explained, "It all started three days ago..."

Three days ago, the FBI discovered the whereabouts of the organization's members. An agent named Aaron was tasked with tracking them, but he suddenly lost contact and his body was discovered the next day.

Then, the day before yesterday and yesterday, several agents were ambushed by the organization and unfortunately killed.

Judy said, "We usually use coded messages to contact each other about meeting places. We suspect that Aaron may have leaked the method to crack the code to them, so we hid here to think of a solution."

"If the method to crack the code has indeed been leaked, they may already know the location of our base."

"I see." Yu said, suddenly understanding, but then frowned. "With so many of you here, what if we're exposed..."

Carmel quickly replied, "Don't worry, we'll soon determine the location of our next stronghold and leave immediately. Until then, we won't go out casually to avoid being discovered by the organization."

At this moment, Conan asked, "Where are Uncle Yusaku and Aunt Yukiko?"

Judy looked at Conan and said, “They went out to buy groceries for us.” She glanced at the large group of people behind her and said helplessly, “It’s too conspicuous for so many people to order takeout.”

James laughed and said, "We have a few agents who are good cooks. As long as we have ingredients, we can solve the problem of eating."

"Oh, I see." Conan's lips twitched slightly. No wonder no one answered the phone at home; his parents had gone out.

The Kudo family's phone was intentionally not set to caller ID. When the phone rang, Judy and the others didn't know who was calling, and since their whereabouts might be exposed, they didn't dare to answer.

Yuya looked at Shuichi Akai, who had now shed his Subaru Okiya disguise: "So, what's going on with your phone being unreachable? I thought you'd been ambushed by the organization too."

Shuichi Akai gestured to his phone: "I'm on the phone with other agents. Our people have been keeping an eye on the hotel that was previously used as a base. We haven't found anyone monitoring the hotel within a one-kilometer radius of the hotel."

Judy looked at Shuichi Akai and guessed, "In that case, the possibility of Aaron revealing the way to decipher the code becomes lower."

Shuichi Akai nodded: "That's right. Judging from their style, they won't force us to tell them how to decipher the code. Instead, they'll interrogate us about the location of the base and then wipe us all out."

Since the location of the stronghold has not been exposed, it means that the organization members have not been able to extract any information from Aaron.

Shuichi Akai's speculation was reasonable and well-founded, and all the agents agreed with this statement.

At this point, James asked Judy, "By the way, have you heard anything from Jim and Chen, who suggested going to the coded rendezvous point?"

Judy shook her head: "Not yet."

Jim? Yu also spoke up: "If it's Agent Jim, he's already been killed."

He then recounted what had happened: "I saw Vodka on the roof, and it's very likely that he pushed him off. If Agent Jim was killed, then Agent Chen has probably met with misfortune as well."

"What?!" Everyone was shocked to hear that Vodka had appeared at the rendezvous point.

James was puzzled: "If Aaron didn't reveal the method for deciphering the code, how did they know the rendezvous location?"

Yuya said, "Could it be that they simply intercepted the phone's information and then directly cracked the code?"

James looked at Yuya with a puzzled expression.

Yuya casually remarked, "Isn't the code just the location, date, and time of the rendezvous?"

"Huh?" James and the others looked surprised. "How did you know?"

Yu shrugged: "I found Agent Jim's cell phone on his body and saw their secret code."

"But how did you..." Judy was stunned.

Yu gave her a strange look: "Isn't the answer to those kinds of codes obvious at a glance?"

"Wh-what?" Judy was even more stunned.

Yuya opened her phone and pulled out the coded image she had specially taken a picture of.

"First, cut out the lower half of the mirror image and cover it with the corresponding position of the original image to form a sequence of three complete rows of letters, symbols and numbers."

"Judging from the location where the agent fell, the meeting place was Beika Town, so the symbol in the first line should be the letter K, which together means BEIKA, Beika Town."

"Then, in the second line, the lowercase u is "U" and the uppercase U is V. Together they form GUAVA, which matches the GUAVA beverage shop near the scene."

"The numbers in the third and last line are the date and time."

“总结下来，这个暗号的内容就是米花町3丁目5番地番石榴饮品店，10月3日16点。”

"What, am I right?"

Judy and the others exclaimed in amazement, "Amazing! Absolutely correct!"

Carmel couldn't help but ask, "How did you figure that out? There's clearly no way to decipher the code..."

Yu looked at him strangely: "Isn't this a super simple code? You can tell the answer at a glance."

Carmel's lips twitched violently: "Simple... We use specialized tools to interpret the flips, you just need to take a look..."

Shuichi Akai also said admiringly, "As expected of you."

Yuya shrugged, indicating that it was a piece of cake.
