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

There wasn't much discussion on this topic.

Chen En then walked towards the secret room in the Bat Cave, through the mechanism door, and took a sip of coffee.

He said.

"Do you remember what I told you before about why I called you to the Bat Cave?"

Chen En's words prompted Conan to recall something.

The Grim Reaper Elementary School student followed behind Chen En and answered directly.

"You said there are some props that you are unable to test and you want us to help you test them."

"But what exactly is that prop?"

"Professor Agasa has never developed any gadgets that require testing, and judging from the conversation between Koizumi Akako and you just now, it's not a magical gadget either."

"What could that be?"

"It's neither a gadget developed by Professor Agasa, nor a magical gadget from Koizumi Akako's side?"

"Did you make this prop yourself?"

Chen En did not respond to this.

He simply arrived at the hidden mechanism door, followed by Conan and Ai Haibara, and then activated the hidden keypad switch.

Enter the password quickly.

Open the secret door in front of the most hidden room inside the secret bat cave.

Seeing this mysterious scene.

Even Conan and Ai Haibara couldn't help but feel a sense of anticipation.

Could it be that this room contains something extremely rare, which is why Chen En needs to guard it so closely?

Even Professor Agasa, who had been browsing through the magic books, couldn't help but look up and take a look at what was inside the defense line.

Then everyone froze in shock.

The room was simply furnished.

The room, constructed entirely of metal, contained several glass pillars filled with objects, but the objects inside were nothing special.

They're just some ordinary-looking things.

For example, a spray bottle with some funny or quirky designs painted on its surface.

"...This spray is usually pepper spray, right? Why is there a shark symbol on the can, and why is there a cross on the symbol?"

Conan stood conspicuously in front of the pillar and retorted without holding back.

"Could this be shark repellent spray?"

"Seriously, how could shark spray possibly work? Let alone whether there's even a spray that can scare sharks away..."

"Isn't it ridiculous to use a spray underwater?"

"If shark spray is to be used on shore, are the sharks supposed to be two-headed or three-headed sharks that jumped out of some low-budget horror movie?"

Ai Haibara's eyes also held a look of doubt.

She didn't understand what the purpose of developing this spray was. It couldn't have been purely for laughs, could it?

Or is this just a purely mechanical deus ex machina?

Is it to show that Batman is omnipotent, so he even has special gadgets to deal with sharks?

"Stop looking at those things."

"This is what I'd like you to help me test."

Chen En arrived in front of the special prop in the core area and his gaze fell on the prop.

"From the moment I got his hands on it."

"Conan, I knew you were destined for greatness."

Conan: ?

Chapter 749 I, the number one iron-headed kid in Ke Xue, am not afraid of you?

What does it mean to say that I am destined by fate?

"You called me here to test this thing? It looks like just an ordinary baseball bat?"

Conan came to Chen En's side.

He looked at the baseball bat inside the glass pillar in front of him, a hint of doubt in his eyes.

"What do you want me to test?"

"How about I test if I can kick this baseball bat in two with a soccer ball? Or..."

Speaking of it.

Conan seemed to suddenly realize something, raised his head, looked at Chen En with a wary look in his eyes, and then said without any mercy.

"You're not thinking of hitting me on the head with a baseball bat, are you? Let me tell you, don't even think about it!"

"From the day Gin knocked me out of the way, I made up my mind that I would never let a second person have the chance to knock me out of the way again!"

"Nobody! Can! Hit me with your club!"

He selectively forgot his previous experience of being ambushed at Yoko Okino's concert.

Ai Haibara came to Conan's side.

A hint of doubt appeared in her eyes as she looked up at the baseball bat in front of her and asked.

"You're not really thinking of ambushing me, are you?"

Chen En did not speak.

"Do you really want to...?"

Ai Haibara was somewhat surprised.

Conan: ?

Why did you suddenly stop talking?

Hurry up and say something to refute me! Your silence is making me a little anxious...?

There was no answer to Ai Haibara's question.

Chen En pressed the button.

The glass dome in front of them immediately rose up.

Harley Quinn's baseball bat fell, but he caught it and held it in his hand. The system panel for this special item reappeared.

【Item Name: Harley Quinn's Baseball Bat】

[Note 1: This is the baseball bat used by the infamous villain Harley Quinn. She has defeated countless superheroes and supervillains with a single blow, even the notorious Shazam the Thunder has not escaped her fate.]

[Note 2: It is said that a baseball bat hit on the head can cause someone to see things beyond the realm of reality for a short time. However, many people insist that it is just a hallucination caused by Harley Quinn's concussion...]

This is a very mysterious prop.

When Chen En first acquired this item, he had already tested it once.

He tapped his head lightly with a baseball bat.

Then it came into his line of sight.

The Mouri Detective Agency has changed.

The streets were littered with steel needles left behind by inconsiderate people, and even Kogoro Mouri, who was sitting across from him, seemed to have changed.

Chen En couldn't be sure whether the problem lay with him or whether Harley Quinn's baseball bat could actually reveal something different.

But in any case, he did not continue the experiment.

the reason is simple.

If Harley Quinn's baseball bat strikes on the head were indeed causing hallucinations, then it could very well lead to schizophrenia.

He can't become another Batman with mental problems.

Inside the world of Ke Xue.

Chen En, who suffers from mental illness, is no less dangerous than the Laughing Bat in the Big Event.

And now it's time to restart the trials.

"This is a magical item."

"It does not belong to the category of magical items, but it does have special effects that are no less than those of magical items, but the specific extent is uncertain."

Chen En said in a serious voice.

"This prop may look like an ordinary baseball bat, but it actually possesses incredible power; all it takes is a single tap on the head."

"It can allow the person who is hit to see a different world!"

Conan, Ai Haibara: ?

Conan's eyes immediately became wary, and he silently took half a step back.

"Do you think I, Detective Conan, would believe your nonsense? What do you mean by seeing another world? Did you give you a concussion?"

"Or did you just knock him off his feet and send him to drink soup in the Sanzu River?"

"I won't believe your nonsense!"

Ai Haibara, standing next to him, frowned slightly.

She was also somewhat skeptical of Chen En's words and offered a warning.

"Is it caffeine poisoning?"
