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

Chapter 187 You are the worst class I've ever taught, Robin
The blue castle is gradually becoming lively.

After driving for several hours in the early morning, the Tokyo Metropolitan Police Department officers, sporting dark circles under their eyes, arrived at the crime scene just before dawn and conducted a thorough search of the interior and mechanisms of the blue castle.

They quickly verified the number of bodies and brought them to justice.

Inspector Megure simply said with a bit of a headache,

"Brother Chen En, how did you manage to find such a remote place this time?"

"If I hadn't asked someone nearby for directions, I would have searched for hours without any sign and still wouldn't have found this place. It's so remote. Why do rich people always like to build villas and castles in places like this?"

—This might be a common hobby among wealthy people in the world of Detective Conan.

Chen En shrugged and didn't say anything.

They simply had the police pull Mutsumi Nishikawa down from the top of the tower, explained the situation briefly, and then had Mitsuru Mamiya and Norito Mamiya retrieve Mutsumi Nishikawa's passport from her room.

The truth of this case is then self-evident.

------

In order to obtain the secret treasure hidden by the patriarch of the Mamiya family.

Nishikawa Mutsumi conceived the idea of ​​impersonating Mamiya Masuyo. She then used a secret passage to set fire to the villa while Mamiya Masuyo's eldest daughter, along with thirteen friends and servants, were holding a banquet in the castle tower. She burned everyone to death in the villa.

This also allowed her, who was then the housekeeper of the Mamiya family, to fake her death and escape.

Subsequently, Mutsumi Nishikawa underwent plastic surgery to resemble Masaki Mamiya, trapped the real Masaki Mamiya in a secret passage and starved to death, and then lived in the castle in Masaki Mamiya's appearance.

They spent four years exploring the secret passages within the castle, trying to find the location of the patriarch's treasure.

Along the way, Mutsumi Nishikawa would also trap other people who discovered the corpses in the secret passages and let them starve to death in the passages. For example, Conan and Professor Agasa were knocked unconscious by her and hidden in the secret room.

Later, she attempted to attack Ai Haibara and the others who had entered the secret passage to search for Conan and Professor Agasa.

The final result is self-evident.

Upon arriving at the Blue Castle, Chen En played a little joke on Nishikawa Mutsumi, causing this 'old lady' who had been pretending to be crazy to go completely insane. It's estimated that she'll be sent to the asylum in Beika Town after the case is heard.

------

"Great detective, don't you always brag about how amazing you are?"

"How could you just disappear without a sound? If Nishikawa Mutsumi had been holding a knife instead of a stick, you would already be dead."

Ai Haibara glanced at Conan, whose head was bandaged, and teased him.

Conan merely frowned at this.

—It's as if you can't be ambushed when you're not on 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 his team had already pulled Masaki Masuyo down from the tower. Curious, Mamiya Mitsuru and Mamiya Takato followed the police up the ladder to see what was inside. Finally, they saw these words inside a 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: ?
Ah this.

What about me?
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!
