Something's wrong with how I'm watching anime.

"But this is only the 'external' usage. In fact, there is another way to use the '戻牌'."

The Clow Card has one of the lowest appearance rates in the original work, and its ability is only manifested in showing the scene at Mizuki Shrine three years ago.

In fact, this card's effectiveness goes beyond that; otherwise, it wouldn't be a high-ranking card that can be matched with the four basic elemental cards.

"The 'reverse card' can also be applied to specific items to restore them to their past state."

"Of course, this restoration is not fixed and has a time limit. This is determined by the return time and the user's magic power."

"In other words, I can transform myself back to a time when my brain was not fully developed."

"And what's most interesting is that this kind of going back to the past only has a physical impact."

Thoughts, memories, and the soul will not be affected.

The effects experienced during the return process will be inherited after recovery.

In other words, if you revert your physical state to the past and cut your palm, the scar will remain even after you recover.

"In other words, if I read the book of wisdom in my past state, the effects will be inherited."

When Kazama first learned about the limitations of the weapon, he was a little disappointed.

After all, without this restriction, one could do all sorts of things by exploiting bugs.

For example, if Kazama were to face off against a parasitic beast, he could use the Reversal Card to reverse half an hour of time before the battle even begins. If he were injured during the battle, he could simply recover to his original state, which would be equivalent to a full-health resurrection.

However, Kazama has now come to like this restriction, since he can use it to exploit a bug in the Book of Wisdom.

"But whether it can actually succeed remains to be seen."

"However, theoretically speaking, there is indeed a high probability of success."

"However, there are still a few problems."

"Cerberus interjected."

"Firstly, using the talisman will consume a large amount of the user's magic power."

In the Clow Cards, the Time combination, specifically the Time and Time cards, are major sources of blue-quality cards.

“I know,” Kazama explained.

“Using the inner self consumes slightly less magic than using the external to conjure up an entire past scene.”

"Furthermore, thanks to my compatibility with this child, I will be able to use it more easily."

"The human brain is basically fully developed by the age of seven. Although there is still room for further development, it would be best to restore me to the physical state of a seven-year-old."

"I estimate that I could maintain this state for about half an hour, reversing the effects of more than ten years of my body's time."

"After half an hour, it will return to its original state because the magic power is exhausted."

"So you're saying you have to finish reading this book in half an hour?" Cerberus asked.

"Then there's the second question: this book must have other limitations, such as the 'cost' involved."

The Book of Wisdom can only be used by children who are not yet fully developed; this is at best a limitation rather than a cost.

The greater the power, the harsher the price to pay.

"Yes, the Book of Wisdom does have negative effects after reading it."

"It not only empowers readers with wisdom but also influences their state of mind."

"To fall into absolute rationality."

"Ok?"

Kerberos was taken aback by Kazama's words.

"What kind of price is this?"

"Rationality is certainly a positive trait; being rational is a good quality."

"But absolute rationality is not necessarily the case."

What does absolute rationality represent? It means that such people only care about the success rate. They won't do something if they know the chance of success is lower than the chance of failure.

In reality, most things in the world have a higher probability of failure than success.

If everyone acted this way, the entire civilization would stagnate.

"What makes humans human is their own subjective initiative, which is independent of material conditions."

Even when faced with adversity, and knowing that the chance of failure is lower than the chance of success, I will still do it.

"Among those who go down in history, how many are geniuses? The ones who truly succeed are more like those who know the chances are slim but still refuse to give up."

"Only such people can reverse adversity and ultimately achieve success."

I'd rather make a mistake than do nothing.

I'd rather do nothing than make a mistake.

Which one is more likely to lead to success?

“I roughly understand,” Kerberos said in a low voice.

"So, what are you prepared to do about the consequences?"

“This…” Kazama smiled.

"Rationality is a way of thinking, and ways of thinking are often formed through the continuous accumulation of experience."

"Once a way of thinking is fixed, it is like a person's personality. It is very difficult to change unless there is a strong external impact. And even if it is changed, it will certainly not be done overnight."

Chapter Twelve Test

The side effects of absolute rationality are unlikely to occur to oneself. This is Kazama's deduction based on information about the "Book of Wisdom" in the original story.

Of course, the specifics are still just speculation before any experimentation. There might even be flaws not depicted in the original work.

Anyone who tries to take shortcuts must be prepared to pay the price.

Having grasped this principle and made up his mind, Kazama will no longer be timid or hesitant.

"Xian!"

As Kazama's eagle-headed wand struck the golden card, the card rapidly melted, and finally, several beams of gray light surged into his body.

With the help of the Clow Cards' magic, Kazama's figure began to shrink rapidly.

The whole process lasted about three or four seconds, after which Kazama truly returned to the age of seven.

Kazama's clothes, which used to fit him well, were now too big; a single T-shirt could cover his entire body.

Is that how Conan feels?

Looking at his own small, immature hands, Kazama felt a pang of sadness.

However, this sense of melancholy was immediately jolted back to reality by the feeling of something continuously flowing away from the body.

The card is constantly drawing out its own magic power.

It really consumes a lot of mana.

The previous estimate that he could maintain this state for half an hour seems to have been too optimistic.

In actual use, Kazama felt that he could last about twenty minutes.

So, we need to hurry.

Kazama stopped pausing and picked up the "Book of Wisdom" beside him, holding it close to his chest.

Upon opening the cover, one's gaze is drawn to the intricate illustrations on the first page.

The view was completely different from before the use of the gong.

If Kazama, in his adult form, read this book and only found the illustrations too rough and complicated, he would immediately get a headache if he tried to memorize them.

So, from the perspective of returning to childhood, the picture is a completely different story.

In Kazama's eyes, the lines drawn on the paper began to writhe.

The black ink lines gradually detached from the book's surface as they moved, forming a three-dimensional symbol in front of Kazama.

The unique symbols exude an indescribable charm, drawing Kazama's attention and spirit into them without his conscious effort.

Kazama suddenly felt his world become hazy and confused, as if he were in a half-dream, half-awake state.

The sense of time slowed down, reaching its limit at a certain point.

At this moment, Kazama's sensory world came to a standstill.

But this stagnation did not last long. Like a dam holding water, when the capacity reached its limit, the mental energy broke through some kind of constraint and burst forth.

In Kazama's perception, it was as if a spark of light had burst forth from the darkness, illuminating the entire world. Like a blind person regaining their sight, something had been completely reversed and changed.

...........

While Kazama was reading the Book of Wisdom, Cerberus was watching over him.

He constantly monitored the magical energy fluctuations around Kazama to prevent any unexpected incidents.

So far, everything is normal.

Kazama's magical energy was being consumed at a steady rate, making it easy to predict his limit.

Before reaching its limit and turning into overdrafting magic power, Cerberus will awaken Kazama.

Unlike Kazama's magic power, which was being consumed at a steady rate, Kazama's reading speed was getting faster and faster.

Kazama spent a full five minutes reading the first page.

There are only three minutes left to get to the second page.

This dispelled Kerberos's initial worry that Kazama might not be able to finish reading the book before running out of magic power.

Later on, it became a habit to flip to the previous page, glance at it, and then immediately look at the next page.

As the pages flipped rapidly, the heavy "Book of Wisdom" grew thinner and thinner until Kazama finally closed it up.

Exactly twenty minutes later, Kazama's magic was completely exhausted.

The power of the card was extracted from Kazama and returned to the card, falling back into the Book of Seals.
