I'm in Detective Conan, and the system has appointed Batman.

Conan merely frowned at this.

It's as if you can't be ambushed when you're caught off guard.

The main reason is that Mutsumi Nishikawa is so familiar with the area that she walks without making a sound.

I wasn't on guard!

"It was just an accident this time. I promise it won't happen again next time."

Conan said with absolute certainty.

The members of the Junior Detective League looked on with suspicion.

Because Conan said the same thing before when he was near the Tokyo Budokan.

However, despite saying it so many times, he hasn't actually become more vigilant at all.

"Thank you so much for your help this time, Mr. Chen En."

Professor Agasa, whose head was also wrapped in gauze, said with great gratitude.

If Chen En hadn't come specifically to bail people out this time...

He and Conan are likely doomed to starve to death in the locked room.

"By the way, how did you find us?"

"I just heard from Ai that she called Inspector Megure. Did you find out from Inspector Megure that we were in danger, so you came here specifically to rescue us?"

This is a topic that absolutely cannot be mentioned.

Chen En gave him a disapproving look.

Don't mention this, it's too hurtful.

Behind him, Inspector Megure and others had already pulled Masaki Mamiya down. Mamiya Mitsuru and Mamiya Takato, out of curiosity, also followed the police up the ladder to see what was going on inside.

Finally, I saw these words inside the hidden door at the top of the tower.

I would like to dedicate this castle and this view to the first person who discovers it.

"So this is the secret treasure left behind by the master."

"Damn it, so many people have died because of something like this! What is Grandpa doing? He keeps spouting nonsense, and now he's acting like a riddle teller!"

"It's Mamiya no Kōjin!" he said angrily from the other end.

Hearing this, Professor Agasa asked curiously,

"Chen En, logically speaking, since you opened that hidden door, you should know what the treasure is, right?"

"Didn't you take it?"

In response, Chen En merely twitched the corner of his mouth and said,

"What are you thinking? The treasure is indeed very precious; it's the entire ancient castle."

"But the family still lives here. The so-called master has been dead for fifteen years. How could they possibly give away the castle as a treasure according to the words carved by the master?"

The master was a legendary riddle teller; could they be too?

Dr. Agasa nodded in sudden realization.

Before Professor Agasa could comment on this, Chen En suddenly spoke to him,

"Professor Agasa, do you see? This is what happens to riddle tellers."

"So, please don't be a riddle teller anymore, okay?"

Dr. Agasa: ?

Oh, this.

Is this any of my business?

After bypassing Professor Agasa, Chen En arrived at Ai Haibara and Conan's side.

Looking at the elementary school student who was like a death god with bandages wrapped around his head.

Chen En was at a loss for words.

He had previously felt that the people of Beika Town were all born with the ability to be knocked unconscious by a club when he was at the East Capital Bank.

Among these holy bodies, there is one holy body among holy bodies.

That's Conan right in front of me.

Despite being hit over the head more than once, Conan still maintains his stubborn personality.

It's hard to imagine how Yusaku Kudo and Yukiko Kudo raised such a stubborn kid.

"Ugh."

Chen En placed his hand on Conan's shoulder, who was sitting in a chair, and sighed.

"You are the worst Robin class I've ever taught."

Although Robin's ways of dying and falling down were indeed varied.

Some of them quite challenge the lower limits of human theoretical understanding.

However, no Robin would fall for the same method every time, so in that respect, Conan has set a record.

Conan lowered his head, looking somewhat disappointed.

Then, he looked up abruptly and realized that something was wrong.

Conan: ?

Wait a minute, when did I admit that I was your Robin?

"In short, I really need to give you a good workout."

"Ai, are you coming or not?"

He grabbed Conan by the back of his collar, deciding his fate.

Chen En turned to look at Ai Haibara.

Ai Haibara paused for a moment before tentatively speaking.

"Come……?"

It is necessary to improve one's ability to protect oneself.

Although the props are very powerful.

However, if you get hit over the head like Conan, then having a lot of gadgets is useless if you can't use them. You have to be strong yourself to succeed!

Chapter 188 Yusaku Kudo's Martial Arts Master Friend

This is a legendary episode that almost wiped out the entire group of the Grim Reaper Elementary School Student, the Junior Detective League, and Professor Agasa.

Blue Castle happily provided him with seventy-five points.

Watching Nishikawa Mutsumi being led into a police car by Inspector Megure and others.

Chen En couldn't help but ponder.

Shouldn't he build a mental hospital too?

It is well known that Japanese mental hospitals have a very poor capacity to control mental illnesses.

In addition, some people left secret doors so that they could use mental illness as a pretext to escape after committing crimes. Therefore, unless someone is truly insane, it is not difficult for anyone with a modicum of sanity to slip out of this mental hospital.

Of course, Mutsumi Nishikawa is definitely not going to get out.

But who knows, there might be other criminals who pretend to be mentally ill to avoid punishment, enter the mental hospital, and then use other means to get out of the mental hospital, and then, having nothing better to do, continue to kill.

Therefore, it is still necessary to build a mental hospital that ensures that once someone enters, they will not leave.

It's better to be safe than sorry.

"However, this plan needs to be extended a little further."

"I don't have enough cash flow to open a mental hospital on the surface... I have to wait until I get my hands on Noah's Ark and use its intelligence as a foundation to enter various businesses."

Chen En pondered to himself.

He is now on a train returning to Tokyo.

Professor Agasa drove his Beetle to take the other three members of the Detective Boys home, while Chen En drove a rented car with Ai Haibara and Conan back to their apartment.

In the back seat, Conan stared at the back of Chen En's head in the driver's seat.

He was pondering how Chen En knew their exact location.

Before leaving the crime scene at the Blue Castle, Conan specifically asked Inspector Megure, who said he hadn't told Chen En about Ai Haibara reporting the crime, meaning Chen En had come looking for him on his own.

However, the Detective Medal ran out of power, and the locator's ability failed.

It's impossible for Chen En to have tracked them to such a remote location as Blue Castle, unless he had placed tracking devices on them, which is the strange thing.

Conan searched his entire body but couldn't find the tracking device.

There was nothing on the outside or inside of the clothing.

Could it be that Chen En could sew the locator inside his clothes?

He was somewhat skeptical of this.

Conan would believe that Chen En was fast enough to steal his phone from his pocket in an instant.

However, he absolutely did not believe that Chen En was fast enough to tear open his clothes in front of him, put the locator inside, and sew it back up without him noticing at all.

Chen En was fast, but certainly not this fast.

"And why are you giving me special training?"

"Even if elementary school students receive training, it's unlikely to yield any useful results."

Conan muttered to himself, then looked at Ai Haibara beside him and asked,
