Starting with "The Demonic Cultivation," I had no choice but to pretend to be a magical gi

"While attacks with corrosive effects are cool, this is the world of magical girls. What magical girl uses skills that emit black smoke?"

Gu Yun bit the end of his pen, his brows furrowed.

"We need to find a way to remove these special effects, and the colors need to be brightened up. We need to give it that 'righteous and noble' feel..."

"You make it sound so easy."

Nightingale couldn't help but complain.

"The essence of my demonic true essence is devouring and erosion. It is a product of extreme yin and coldness, refined bit by bit. How can it be changed so easily?"

"Ha, typical downward revision thinking!"

Gu Yun didn't even look up, scribbling in his notebook as he casually replied.

"Power is power. How can power be wrong? There is no such thing as useless power, only useless users. You'll see how powerful it is once I figure it out."

As he said this, he pulled out a book with a gaudy cover called "Do You Really Understand Magical Girls? The Little-Known Secrets," and then took out a thick stack of printed manuscripts stapled together, which he spread out on the ground.

The title above is very eye-catching.

The astonishing connection between the ten unsolved mysteries of the mortal realm and the origins of magical girls (Top Secret Post by the Author)

Nightingale hadn't really wanted to talk to him, but after hearing what he said, she actually started to feel a little resentful.

I'd like to see what your brilliant theories are!

Curious, he peered out and glanced at the jumbled documents that Gu Yun was flipping through.

This is quite something.

Rebirth: I Became an Idol Among Magical Girls

After get off work, I Became a Magical Girl

Even a magical girl can dominate for eternity.

At first glance, it was all things that could make your heart stop beating.

She even saw a tattered magazine, and on the page it was open to, it clearly stated...

"After three days and three nights of surveillance, we've finally discovered the secret behind the magical girls' power—in fact, there are no magical girls in this world; they're all imposters!"

"ha?"

The nightingale felt its mind go blank and made an ambiguous sound.

"You...you rely on these things..."

Her voice was trembling.

"With these worthless junk, they seized control of my Golden Core?"

What is garbage?

Upon hearing this, Gu Yun immediately became displeased and decided to have a serious discussion.

"This is called combining the strengths of many schools of thought. It is the crystallization of my wisdom collected over the past three years from various forums, secondhand bookstores, and some mysterious merchants."

"Look how well these theories are written, how valuable they are. You can't get them through ordinary channels. If I hadn't been quick-witted, they would have been taken down by the invisible hand of the censors."

The nightingale finally smiled with relief.

"Nonsense! Utter nonsense! Have these authors ever practiced demonic cultivation? They're just writing gibberish, making things up!"

As a dignified Golden Core stage demonic cultivator, Nightingale believed that she had a fairly good understanding of the cultivation of demonic paths.

I have cultivated demonic arts and reached the Golden Core stage; this is not just wishful thinking.

Then, watching Gu Yun treat these baseless fabrications as treasures, and even solemnly summarize them into theories in his notebook, I felt completely disgusted.

This is neither a demonic path nor a magical girl!

"Narrow-minded and inflexible."

Gu Yun confidently offered his evaluation based on eight characters.

How could a time traveler be wrong? It's perfectly reasonable that they could find forgotten fragments of ancient secret techniques while casually browsing a used bookstore.

"As we all know, truth is often in the hands of a minority."

He shook his head, deciding not to argue any further.

I thought this Golden Core stage demonic cultivator would be able to glean some insights from these fragments, but I never expected him to be such a pedantic fellow.

nightingale:……

She gave up arguing.

After all, arguing with someone who has a problem with their brain is actually quite degrading and pointless.

"I'm not angry, I'm not angry..."

The nightingale is trying to comfort itself.

Gu Yun didn't care what she was thinking; he already had an idea in his mind.

Based on her previously summarized fully automatic magical girl disguise method, she immediately began to update and fine-tune it in various aspects, striving to make the disguise more convincing.

"It's decided. Whether it's attack or defense, it has to be packed with special effects. All sorts of complex and incomprehensible geometric shapes will be piled on top. The more incomprehensible they are, the more sophisticated they will appear."

Immediately afterwards, he pushed the pile of messy books aside, leaving only the notebooks.

"Hey, you there? Stop playing dead and cooperate with me, otherwise it'll be a real hassle for me to fix things if you keep messing around."

In fact, even now, Gu Yun still doesn't know what Nightingale's name is.

The nightingale remained silent for a long time.

"...You will get your comeuppance."

After a long pause, he finally managed to utter this sentence.

"I can cooperate, but after you finish making the changes, you are not allowed to misuse my demonic true energy. I need to concentrate on repairing my golden core..."

As Nightingale spoke, she herself felt that she was being a little too naive, and her tone softened involuntarily, carrying a hint of pleading.

"...At least, at least you should tell me before you use it, right?"

"Yes, no problem."

Gu Yun answered casually, it was unclear whether he had actually listened or not.

Time passed little by little.

The next morning arrived quickly.

As a senior high school student, Gu Yun naturally needs to go to school.

After all, if she doesn't go to school every day, it's easy for the Magical Girl Association to become suspicious.

If one's identity were to be exposed because of such a trivial matter, it would be a great loss, so it must be avoided at all costs.

So the morning sunlight streamed through the window, dappling the desks.

Having not slept all night, Gu Yun lay slumped on the table, staring at the teacher giving a history lesson on the podium, feeling utterly listless.

Studying magical girls can really be harmful to your health.

"...Back then, the demonic path raged, and the land was devastated. It was the darkest period in human history."

The teacher tapped the blackboard, reviewing modern history.

"Until fifty years ago, the magical girl Ruri appeared out of nowhere, single-handedly conquering the north and south and pacifying the rampant demonic forces in the Nine Provinces. This content, as the beginning of modern history, is a required topic in every year, and everyone must master it firmly."

Gu Yunqiang mustered his strength and listened intently.

Even if he had heard about magical girls and magic countless times, he wouldn't let go of anything related to them, because there might be key information in them that he hadn't noticed before.

"As a high-ranking cultivator of the demonic path, what are your thoughts?"

Gu Yun looked at the glass illustrations in the textbook for a moment, then suddenly remembered something and spoke to the thing in his mind that he didn't know what to call it.

"That's utter nonsense!"

In fact, the nightingale is indeed very excited right now.
