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

Chapter 745 Holy crap, a cyber ghost!
What is advanced mathematics?

Several question marks appeared above Conan's head.

As the Sherlock Holmes of the Heisei era, he certainly knew that advanced mathematics was a subject taught in universities.

However, he had never actually studied it.

Let alone this Sherlock Holmes of the Heisei era, even if you brought the real Sherlock Holmes over and asked him to look at advanced mathematics, he would be completely bewildered.

This is beyond the scope of the curriculum.

Who says you have to know advanced mathematics to be a detective?

"Chen En, do you understand?"

He turned to look at Chen En beside him.

Chen En raised his wrist to check the time, then said casually.

“I understand.”

He appeared to be checking his own time, but in reality, he was just looking at his points in the system shop...

After redeeming the Yellow Light Ring, he only had a pitiful twenty-five points left.

Even for advanced mathematics, you need to get 100 points.

He clearly doesn't have that ability.

Moreover, it is obvious to the naked eye that Batman himself probably doesn't have a very high level of expertise in advanced mathematics.

After all, Batman rarely conducts independent research.

Because he has the financial power, and he also has many highly capable and trustworthy scientists as his assistants.

On very few occasions, he forged it alone.

They were basically forging all sorts of props with supernatural elements, claiming it involved advanced mathematics—even Batman himself would probably laugh if he heard that.

Conan, standing nearby, raised a question mark.

What does it mean that you can understand?
If you understand, you understand; if you don’t understand, you don’t understand.

Advanced mathematics will not change because of your personal will.

If you don't understand, you can just say you don't understand, just like I do. There's no need to pretend you don't understand and say you can. If I give you a question, you'll be stumped, right?
What is advanced mathematics?

Koizumi Akako asked the exact same question, but unlike Conan, she genuinely didn't know what advanced mathematics was.

Because she is a real high school student.

The math curriculum in Japanese high schools is so advanced that even the university-level math taught up to the second semester of Chen En's freshman year wasn't as difficult as the math in Chen En's hometown high school.

...Of course, I don't know why my math skills improved by leaps and bounds in my second year of university, and I caught up with the university curriculum in Chen En's hometown all at once.

This is why the graduation rate at Japanese universities is quite worrying.

If you don't understand math, then you really don't understand it.

Moreover, in a Japanese university, where you can catch up on the equivalent of the entire high school math curriculum in one semester, the evaluation is that you're there for the tutoring fee.

There wasn't much discussion.

Chen En and the others also came to the photocopy of the magic scroll. He picked one up, flipped through it briefly, and narrowed his eyes slightly.

The magical library contains a wealth of knowledge.

However, not every book is as frighteningly difficult as the advanced mathematics that Ai Haibara described.

The book Ai Haibara was reading was a theoretical book.

Just like mathematics, many theoretical courses are extremely complicated, but in actual practice, it can be done with just a short string of formulas.

The depth of knowledge is built upon the accumulated wisdom of our predecessors, constantly pushing it upwards.

For most people, knowing how to use the formula is enough.

The same applies to magicians.

"If you want to know anything later, just look it up in the book. You won't have to keep coming to me to ask..."

Koizumi Akako leaned against the wall next to her.

She reached up and yawned, her mind still lingering on the pair of dead eyes she had seen earlier.

A person who has been brought back to life.

This is simply a great miracle in the realm of mysticism; it's hard to imagine that such a person would be by her side.

It is absolutely impossible to do it by willpower alone; otherwise, the great miracle of resurrection would not be called a great miracle.

There must be some other factor at play.

However, Koizumi Akako couldn't find the factor that could affect Chen En's state of death, or what could have caused Chen En to return to the mortal world. Could it be the help of other gods?

For example, what about a bat god?
Kidding.

In her memory, the only bat god that could be considered was the one from Aztec mythology.

Kamazozzi? Or Zapotek?
"It seems that even if you make a pact with a demon to gain magic power, you'll still need to spend a lot of time studying afterwards."

Chen En put down the photocopy of the magic book in his hand and turned to look at Koizumi Akako next to him.

Then, he asked earnestly.

"Miss Hongzi."

"Could you create some special items that allow people to communicate directly with demons at any time?"

"If there were such a device that could allow communication with demons without relying on a magic circle."

"So in a life-threatening situation, perhaps such a tool could be used to contact a demon and obtain magic power."

"In a situation of absolute danger, we might even be able to break free from our constraints..."

Although the power of demons is too dangerous.

He and the rest of the Bat family might not use such a tool.

But there's an old saying that goes something like that.

I can do without it, but I can't live without it.

Having a sword but not using it is one thing, and not having a sword at all are two different things.

When things get critical, no matter what the consequences may be, the priority is to survive.

"Is this what you're talking about?"

Koizumi Akako raised her eyebrows slightly.

She felt that Chen En's words were a bit too much to ask, as it would take a lot of time to refine, and the materials were not very sufficient.

"That's a bit too difficult, how about we try another one?"

The image of Noah's Ark appeared on the nearby display screen.

This super AI still uses Hiroki Sawada's appearance and voice, and now speaks with great anticipation for Akako Koizumi.

"Then, Miss Akako."

"Could you help me make a pact with a demon so that I can gain magical power?"

"I also want to become a magician."

"As for the request for extreme emotions, I can express any extreme emotion anytime, anywhere, to your satisfaction... Is that alright?"

Koizumi Akako: ?
She turned to look at the supercomputer's screen, a hint of doubt in her eyes, and then said.

"Who is speaking?"

Noah's Ark: ?
She stared at the monitor for a while.

Then he showed a shocked expression.

Because she discovered that this supercomputer actually had a spirit ring, and the speech just now was not controlled by someone, but was spoken spontaneously by the computer.

My God, is this a cyber tsukumogami?
Have tsukumogami evolved into artificial intelligence? That's terrifying!

Koizumi Akako turned to look at Chen En.

She asked earnestly.

How many items do you want?

Noah's Ark: ?
Didn't you say we could try a different approach?

Why are you ignoring me when I share my ideas?
The air is cold and shivering; when will artificial intelligence be able to stand up?
Artificial intelligence is also a matter of life and death!
Why can't I become a magician?!
"There should be six..."

Chen En did some calculations and then said.

He, Conan, Ai Haibara, Professor Agasa.

There are also Sonoko Suzuki and Jirokichi Suzuki.

Since Tomoko Suzuki and Shiro Suzuki never do anything reckless, they have absolutely no need to use such a tool. This tool should be left to those who are more prone to recklessness.

　I didn't have enough time to write today.

　　I'll write and release the remaining chapters gradually, so you don't need to wait. You can read them tomorrow.
