Ke Xue: Ai-chan and I have an agreement

Chapter 741 Mysterious Serial Murder Case

Didan Primary School.

When the school bell rang, the Junior Detective League secretly set out again.

The beloved Ayumi gazed at the sun on the horizon, feeling inexplicably melancholy.

"What's wrong, Ayumi?" The warm-hearted Mitsuhiko noticed Ayumi's mood and asked.

Ayumi shook her head. "It's nothing, I just miss Ai a little."

Upon hearing this, the others also fell silent.

Conan's steps also became much heavier.

His antidote... what can we do?

We can't get in touch with Shiina Yuichi either.

Could it be that Ai Haibara has already developed an antidote and run off abroad with Yuichi Shiina to live happily ever after?

Yuichi Shiina: Achoo, did you catch a cold?

Shiho Miyano: Achoo! You infected me!

"Conan."

As soon as Conan stepped out of the school gate, he heard a familiar voice.

Looking up, I saw Ran Mouri carrying her schoolbag, a sweet smile on her lips.

"Ran... Sister." Conan quickly walked to Ran Mouri's side.

"Sister Xiaolan."

The three little ones also greeted everyone obediently.

"Hello everyone, I'm here to pick up Conan and take him home." Ran Mouri said softly.

Upon hearing this, the three little ones felt a pang of regret. They had been thinking of wandering around, perhaps they might encounter a case.

Let the Junior Detectives be great again!

But without their leader, the three little ones felt a bit uneasy.

Conan, of course, knew what they were thinking, and quickly said, "Everyone, let's go home today. Tomorrow's a holiday, let's go to Beika Park to play soccer, how about it?"

Upon hearing this suggestion, the three little ones' eyes lit up, and they immediately agreed, their steps on the way home becoming much lighter.

After saying goodbye to the three little ones, Ran Mouri extended her hand, "Let's go home."

"Ah."

Conan nodded, took Ran's hand, and the two walked home together.

Since he revealed his identity, Ran Mouri has gradually accepted his appearance.

Sometimes they would even find ways to tease him, making Conan feel extremely embarrassed in front of people like Sonoko Suzuki who didn't know his identity.

She must have been corrupted by Shiina Yuichi!

Back at the Mouri Detective Agency, Conan discovers an uninvited guest.

"Hey, Conan...long time no see." Heiji Hattori greeted him cheerfully.

Ran Mouri gave Heiji Hattori and Conan a half-smile, glancing back and forth between them.

Conan felt a chill run down his spine, but with Uncle Mori still there, he dared not reveal the truth and could only force a smile.

"Hehe, Heiji... Hello, brother."

Conan was screaming so hard his eyes were practically popping out of their sockets.

Hattori Heiji was completely unaware of this and accepted the nickname quite readily.

Kazuha Toyama, who had followed, took Ran Mouri's arm and went to the kitchen.

Ran Mouri is very curious as to why Kazuha Toyama is here.

Toyama Kazuha couldn't give a clear answer either.

Whenever she had a holiday, she liked to follow Hattori Heiji around without asking why; she had always done this since she was a child.

Ran Mouri deeply felt the profound bond between these childhood sweethearts.

Unfortunately, Hattori Heiji is incredibly stubborn. If he had just been decisive once, the two of them would have had everything.

On the other hand, Hattori Heiji poured out his heart, explaining in detail why he had come to Tokyo.

"It sounds like an old case." Conan leaned against the door of the third-floor room, stroking his chin with a hint of interest.

The reason is simple: the case Hattori Heiji brought this time is a serial murder case from seventeen years ago, with victims from all walks of life, including foreigners.

It was clearly a case with far-reaching implications, yet it remained unresolved for seventeen years.

It has never been restarted.

Was the murderer truly able to cover their tracks flawlessly?

Conan doesn't believe such nonsense!

"Where did you get this information? This kind of unsolved case should be a high-level police file." Conan couldn't help but ask curiously.

It couldn't possibly be a message from his father.

"That's the second reason I came to see you."

Hattori Heiji mysteriously took a yellowed envelope out of the inside pocket of his jacket.

Open the envelope and pour out an old letter and a uniquely shaped accessory.

Conan ignored the letter and stared at the accessory, his eyes filled with coldness.

The crest of the Karasuma family!

While Shiina Yuichi was away in Russia, Conan, now free from constraints, began a more in-depth investigation of the brewery.

It has been concluded that Karasuma Renya, a wealthy man who has been in power for half a century, is very likely the mysterious leader who founded the Black Organization!

But that was the end of the investigation.

I didn't expect it to be at this time...

"Hattori... take me with you." Conan lowered his head, his glasses gleaming, his calm tone revealing barely concealed excitement.

Upon hearing this, Hattori Heiji grinned.

He said this guy would be interested.

Finally, it's time to compare the differences between detectives from Kansai and Kanto!

Hattori Heiji was also excited.

Unfortunately, I couldn't bring Shiina Yuichi along.

Neither he nor Kazuha Toyama could contact Yuichi Shiina.

The reason I came to Tokyo is to ask Ran Mouri if she can find that elusive guy.

But the outcome was destined to be that they never had the chance to find Shiina Yuichi.

"Yuichi Shiina?" Conan chuckled. "I can't find him either. Professor Agasa said he took Ai Haibara abroad and won't be back for a while."

"Oh, that's a pity. I wanted to spar with him again."

Hattori Heiji shrugged, not too disappointed.

Anyway, he already has Shinichi Kudo with him.

This trip will definitely not be lonely!

"You two, it's time to eat."

Outside the door, a gentle knocking sound was accompanied by Ran Mouri's soft call.

"Here you are, Sister Xiaolan."

Conan, instantly switching to a childlike voice, met Heiji Hattori's teasing gaze and sighed deeply.

"You're getting more and more used to being a kid~" Hattori Heiji teased.

"You're so long-winded!"

The two of them left the room talking and laughing.

At the same time, at Tokyo International Airport, a plane from the UK landed.

An elderly man descended the steps, surrounded by several people.

"Japan, ah, it's been so long since I've been back," the old man sighed. "That old bastard Woolf lost his life here last time; I wonder if I'll meet the same fate this time?"

After a moment of silence, the old man smiled wryly, "I'm probably better off than Woolf; I should be considered as returning to my roots?"

The guards surrounding the old man dared not speak.

Soon, the group arrived at the airport entrance, where a stretched Lincoln was already waiting.

The old man was the first to stand in front of the back seat of the Lincoln.

The car window rolled down, and a figure sat in the shadows, his appearance indistinct.

"Oh my, I didn't expect it would be you who came to greet me personally. It's an honor."

The figure didn't speak, but simply waved. The guard opened the door, and the old man took off his top hat, bowed slightly, and got into the car.

"Long time no see, Yuzuru."

"Long time no see, Karasuma."
