Conan and Gin are both my brothers, what's wrong with meeting them once?

Conan is no longer Shinichi Kudo.

So he had no choice but to obediently greet Hiromi Yabuuchi: "Hello, Aunt Hiromi, I'm Conan~"

Yukiko Kudo chuckled and ruffled Conan's hair twice before tucking him into Kazuma Kudo's arms. Smiling, she asked her friend, "What is it that you asked me to help investigate?"

"Is such that……"

Hiromi Yabuuchi gave a brief explanation.

Her father has passed away, leaving behind a considerable estate, which will soon be announced by a lawyer.

But three days ago, my uncle, Yoshifusa Yabunouchi, who had been in Brazil for almost thirty years and hadn't returned, brought back a close friend who was much older than him.

That's my father's own brother!

The return of Uncle Yoshifusa means that there will be another person to share the inheritance with them. Although Hiromi Yabuuchi doesn't have much of an opinion on this, the other family members obviously cannot accept it.

Then they came up with a plan—if they could prove that this adopted uncle wasn't real, he wouldn't be entitled to share the inheritance with everyone!

In response, Kazuma Kudo couldn't help but give a thumbs up: "Manta-nyan, that's a brilliant idea! But have you ever thought about what to do if the investigation proves that the old man is really right?"

"One...cough! Shinichi!"

Without even looking, Yukiko Kudo poked Kazuma Kudo, who was standing behind her, with a finger.

Guangmei might not realize it, but she understood perfectly well that this brat wasn't praising their genius at all; he was clearly being sarcastic...

Sigh, although she also felt that this method was a bit silly, it was best not to say such things in front of her good friend.

Kazuma Kudo shrugged.

In his opinion, if those people really didn't want to leave any inheritance to the old man, they might as well have all agreed to insist that the adoptive uncle had already passed away, so this one must be an imposter...

"Guangmei, have we had any guests?"

A short, stout, bald old man with white hair and beard walked out from inside.

“Uncle Yoshifusa?” Hiromi Yabuuchi pushed Yukiko Kudo forward. “Do you remember Yukiko? She was my good friend who used to come to our house to play when we were little.”

The old man said uncertainly, "Really? I've been in Brazil for so long, I can't remember..."

He smiled and said, "Since you're a friend of the Guangzhou Academy of Fine Arts, why don't you stay at my house a little longer?"

At that moment, a tall, foreign young man with a complexion almost matching Hattori Heiji walked up behind Yabunouchi Yoshifusa.

Just as Yabunouchi Yoshifusa was about to tell the young man to leave, Kudo Kazuma spoke up, "Grandpa Yoshifusa, you seem quite capable. You're still so strong now; you must have been incredibly powerful when you were young!"

Yabuuchi Yoshifusa was slightly taken aback, then explained, "When you're in a foreign country, you always need to learn some self-defense techniques. You can tell that, so you must be pretty good at it too."

After saying that, he ignored the others and called to the young man beside him, "Carlos, let's go."

After the two left, Yukiko Kudo looked at her youngest son: "Shinichi, did you figure something out?"

Conan, no longer caring about his bratty younger brother stealing his number in front of him, looked up and waited for his brother to explain his discovery.

At least he has now admitted one thing: although Yi Zhen was frail and sickly since childhood, he was actually quite capable in a fight.

Hmm, she might be about the same level as Xiaolan.

Kazuma Kudo nodded: "That old man is definitely a master of Brazilian Jiu-Jitsu, and he probably has forty or fifty years of experience. I can't be wrong!"

The reason is that he was incredibly impressed with Brazilian Jiu-Jitsu!

Back then, he learned a lot of fighting techniques from Gin and the various martial arts masters arranged by Gin. He believed that he had a good understanding of common fighting techniques and could use his speed to escape or even counter those techniques that were extremely fast.

So at that time, he felt that apart from not being able to beat Gin, he could remain undefeated against others even if he couldn't turn the tables. So he became quite arrogant and caused trouble for Gin at the organization's American branch every day.

Frustrated beyond endurance, Gin hired a Brazilian Jiu-Jitsu expert to teach him a lesson...

Thinking about it now, Kazuma Kudo still feels annoyed—for someone like him who relies on speed, that person's Brazilian Jiu-Jitsu was just too annoying!

Without thinking twice, he immediately launched into a close-quarters grappling attack, making it impossible for the opponent to break free, and constantly trying to throw him to the ground...

He had already lost to that person more than ten times in just a few months, and now Gin actually came to mock him?

Enraged, Kudo Kazuma unleashed his full power, using all the spare points he had to improve his fighting skills, and instantly defeated the Brazilian Jiu-Jitsu expert who was relentlessly pursuing him...

Then Gin began to suspect him for the first time.

Previously, he would let his spirit slowly strengthen his body, since he didn't have many points, so he would strengthen his skills little by little.

It would be problematic if this sudden outbreak didn't arouse suspicion.

But things are different now. After being suspected so many times, Gin has gotten used to it...

Regardless, Brazilian Jiu-Jitsu did leave a deep impression on Kazuma Kudo, which is why he could tell at a glance that the old man's Brazilian Jiu-Jitsu was quite impressive.

“That shouldn’t be the case.” Hiromi Yabuuchi looked puzzled. “Uncle Yoshifusa never knew anything about Brazilian Jiu-Jitsu before.”

"Besides, he's only been in Brazil for thirty years, he couldn't possibly have forty or fifty years of experience... Could it be that this adoptive uncle really has a problem?"

Yukiko Kudo shook her head slightly: "Although I used to come here often when I was a child, I remember Uncle Yoshifusa moved away when we were just about to start elementary school, right? So many years have passed, I can't remember what he looked like when he was young at all..."

Hiromi Yabuchi sighed, "My uncle has been gone for too long, and all his old friends have passed away one after another. Now, the only people we can find who are familiar with him are the two of us."

"But so much time has passed, I can't really remember what he used to look like, but something just felt off. And now that Shinichi said that, I feel even more uneasy..."

Conan, standing nearby, asked curiously, "Don't you have any old photos at home?"

Hiromi Yabuuchi shook her head: "Back then, photography skills weren't good, so there weren't many photos to begin with. Uncle Yoshifusa even took all the photos with him when he left..."

Kazuma Kudo followed up with, "Has he never corresponded with you or sent you any photos all these years?"

Hiromi Yabuuchi shook her head again.

"Alright, let's solve everything with science then." Kudo Kazuma shrugged. "How about we do a DNA test?"

Hiromi Yabuchi was a little troubled: "Tomorrow night at ten o'clock, the lawyer will come to announce the distribution of my father's estate. Before that, the DNA results will not be available at all..."

Kudo Kazuma was speechless.

Okay, with current medical technology, DNA results can't come out that quickly unless it's sent to an internal research group for verification...

Isn't this a joke?

"Then I think we should go and look for any old photos, letters or anything like that."

If scientific methods don't work, then we have to resort to scientific methods.

Let Conan figure it out himself.

Anyway, if he remembers correctly, Yusaku Kudo will also appear.

With two expert detectives like Conan and Yusaku Kudo around, why should he worry?
