The existence of "the book" is very special to the world of if - no, to all the worlds related to the book.

Its complexity cannot be summarized in a few words. In the world of if, if more than two people know about the "book", it does not mean that the world will be destroyed immediately, but it will increase the probability of the world's collapse, become more unstable, and more prone to accidents.

As for how much knowledge of "the book" is required to be included in the calculation of this number, Shi Wu did not know.

He only stayed in the world of if for 24 hours, and most of the time was wasted on sleeping. At that time, he never thought that he would appear in the main world that is closely related to the if line.

All the previous worlds have never had such a situation (or it has, but he just didn't notice it at the time).

At that time, Shiwu saw Mori Obi, who knew nothing (at least on the surface), and Nakajima Atsushi, who knew a little but concealed the real situation.

With just these two people, Shiwu was able to guess the current level, which was already very good.

But because of the lack of intelligence, Shiwu thought in a more extreme direction, and because of this lack, the logic and rationality of his thoughts were raised a lot.

Because it was too reasonable, coupled with the confidence and arrogance of the vest itself, Shiwu stopped thinking about it - the deeper he went, the more convinced he would be of his own ideas.

Because the performance of Nakajima Atsushi and the white god of death at that time proved this point in all aspects.

And... the atmosphere that Shiwu felt in the two worlds was also different.

The previous world, the world of if, belongs to the leader Dazai - it is sad and repressed. Nakajima Atsushi expressed his emotions, and Mori Ogai's eyes looking at him actually carried the same emotions, but the mature adults suppressed them in their hearts and did not show them much.

Regrets are often easier to remember than beauty.

In this world, from the beginning, most of what Tokiwa felt was happy, beautiful, and happy.

Although he knew that his comparison was also unfair - whether it was the different world backgrounds, the different vests' personalities, or the different positions - but at the same time, he received different treatments from two vests, and Tokiwa still felt a little... sad.

He couldn't complain for the other world, because this comparison was unfair. Every world has its own rules.

It's like people in the wartime, after experiencing that bloody history, after a few decades, the world is peaceful, and what they see is no longer the smoke of gunpowder, but the smiling faces of people - that kind of emotion overflowing from the bottom of their hearts.

They will compare their past lives with the lives of children now, and may be envious, but they will not have any hostility. They may sigh and wonder what it would be like if they were born in such a peaceful era, but it was those sad and disgusting wars that made them what they are now.

If the leader Dazai had the opportunity to see this world, what would he think... Hmm? Wait? Seeing this world...?

Tokiwa's brain started to turn again.

The White Death said that the clothes he was wearing were very similar to those of an employee of the detective agency. Obviously, to the White Death, this employee (that is, Oda Sakunosuke) was a stranger.

Alice and Mr. Mori know that staff member, and the source of the information is unknown. Given the openness of the detective agency in this world, it is not surprising that Mr. Mori, as the director of the orphanage, knows someone from the detective agency. Especially since Mr. Mori is a former mafia leader, it is even more normal for him to know these things.

The White Death is the one who stays with Dazai Osamu. And the clothes on Dazai Osamu in this world (the main world) are the same as what he wore at the time. Leader Dazai is obviously not wearing similar clothes.

And Oda Sakunosuke in the main world died, while the Oda Sakunosuke in the if world is still alive.

Dazai Osamu's personality would never make him become a meaningless leader for no reason. Shi Wu, who has been in a vest, is the most qualified to prove this.

If you want to be a leader and still be a corporate slave, you might as well commit suicide! With the mentality that the vest had at the time, Shiwu thought that this idea was completely fine.

In addition, the special person mentioned by the White Death, the regret of Chief Dazai was that he had never read the novel written by that person.

Once the logic is connected together...

"...Is that so." Shiwu understood the answer, and this answer made him feel even more sad.

Shiwu knew from the beginning that Chief Dazai was protecting that world for his friends. Only now, he realized that the Chief Dazai was so special.

The Dazai Osamu who became the leader had the ability to observe parallel worlds. He knew that his friend would die, so he chose to do so.

But the regret is that he had never seen that book... In other words, in the world of if, Chief Dazai and his friend did not know each other.

Edogawa Ranpo stood aside and stretched out his hand to hold Shiwu at a loss.

After he turned around and saw Tokiwu's expression, he knew that he had said the wrong thing. Tokiwu could not get this information from this information, but Edogawa Ranpo had seen the memory read out by Ishikawa Takuboku.

Even though that memory was only a short paragraph, the information in it was enough for Edogawa Ranpo to understand that in that world, there was such a special existence that could not be known by more than two people.

He was not sure what it was before, but now he is sure that it is "book".

And "book" is obviously a keyword that makes the other self recall something bad.

How to describe the expression he saw? Edogawa Ranpo tightly grasped Tokiwu's hand.

It was clearly right in front of him, but that expression made Edogawa Ranpo feel that he was very far away from the other person. That sense of alienation that separates the world, his simple word made the other party realize the distance between them, their differences.

Edogawa Ranpo can easily say the word "book", and the whole world will fight for "book". But for another world, "book" is the sword of Damocles that is enough to destroy and collapse the world.

It is not allowed to be known by more people, and is guarded by him (Toki no Shino) and them, paying an unimaginable price.

From the video recording of the memory, it can be known that Nakajima Atsushi (White Death) is one of them, and the other, will it be "Ranpo"? No, it's not - even "Ranpo" is guarding the two people who know the secret.

[For everyone, I must protect the two of you!

I must...

find a way to stop him...

before I...die...]

How could he ignore the words he saw in the red photo at that time?

Ranpo Edogawa understands himself, but he finds it hard to understand why he would burst out with such protectiveness - he knows himself too well, understands his indifference to the world, and his childish cruelty, just like when he initially refused to save Atsushi. He

is like a kite hanging in the sky, being held by the president so that he does not lose his connection with the ground.

For "Ranpo Edogawa", the world has never been important. What is important is only the special individuals in it. Is

there someone in that world who is so important to you?

Why don't you run away? It obviously has nothing to do with you

, right? Who did you meet?

Ranpo Edogawa, who is difficult to understand, does not know that he will put himself in danger of death for the detective agency in the future. Because he trusted the president, he lost the simplest judgment - reasoning is obviously what he is best at.

Just because of the president's words, he never thought about the possibility that the enemy would be that person.

Now Edogawa Ranpo only feels panic, like a child who has done something wrong but doesn't know how to make up for it.

Edogawa Ranpo likes another self very much - this is a very unexpected thing, but it doesn't seem strange.

Edogawa Ranpo is willful and selfish. People like this often dislike people who are similar to themselves. The simplest example is that the snacks that were originally given to himself need to be divided into two because of the existence of the other person.

But he is different. Edogawa Ranpo has been a special child since birth. He cannot understand the world of ordinary people, and others cannot understand the world in Edogawa Ranpo's eyes. So communication is always very tiring.

So when another person appears who can perfectly match oneself and understand oneself, who is different from usual, and who can understand oneself without having to speak in complete sentences, even if the logic jumps quickly.

If the other person's eyes were not invisible, the tacit understanding between them would definitely reach the level where they can understand each other with just one look - even if they can't see, their current situation is almost the same.

The snacks they like are the same, and the things they hate are the same, they can share and complain together.

In the eyes of others, the relationship between the two is that Edogawa Ranpo is taking care of another self, but in reality, Edogawa Ranpo does not think that he is taking care of himself. They are equal, and he has also received the due rewards and emotions from his other self.

This period of time is the happiest and most relaxed life for Ranpo, except for getting along with his parents and the president.

Therefore, Edogawa Ranpo didn't want his other self to be unhappy at all.

Especially when it was caused by himself.

"...What did you remember?" Edogawa Ranpo even opened his eyes.

Shi Wu was not surprised at all that Edogawa Ranpo saw through him. But the things he "remembered" did not belong to "Edogawa Ranpo", but to another alias.

He just finally figured out what happened to the leader Dazai after a while. Just because he had logged into this alias before, he felt a little...sad at this moment.

It was like watching a sad movie, and the aftermath had not yet worn off. Shi Wu thought so, and didn't want to make Ranpo worry, so he replied: "It's not a big deal."

Without waiting for Edogawa Ranpo to answer, Shi Wu took the initiative to say: "I want to go out for a walk."

Before the detective said "I'll go with you", Shi Wu added: "Alone."

Edogawa Ranpo obviously didn't want to agree, and showed his dissatisfaction.

"Don't worry, I know the way." Shi Wu smiled, "And I have a cell phone, I can contact you anytime."

He didn't want to let his slightly bad mood affect Edogawa Ranpo.

Edogawa Ranpo looked at the calm smile and couldn't refuse at all, especially after discovering Shi Wu's thoughts, and with a certain guilty conscience. In the end, the detective just muttered something in a low voice, and then said, "...Come back early."

Tokiwa responded with a smile.

Because he didn't meet the group directly and didn't go out, Edogawa Ranpo didn't realize that the group's attack on the detective agency had started as early as when they were rejected by Fukuzawa Yukichi's "purchase of supernatural business license."

The time was not mentioned in the file, and Tokiwa, who just wanted to go out for a walk, didn't notice this either.

When he went out, Tokiwa greeted Nakajima Atsushi, Dazai Osamu and others who were outside with a normal attitude.

Because Tokiwa occasionally went to the rooftop alone to get some fresh air, no one noticed anything wrong. Except Dazai Osamu.

However, Dazai Osamu did not have any special thoughts. He just glanced at Edogawa Ranpo's office, thinking that they could solve it internally, and shrugged his shoulders and lay on the sofa to continue fishing.

Shiwu did not remember the roads, but he could recognize the way if he needed to. With the idea of ​​taking a casual walk and feeling the sea breeze, Shiwu pressed down the hat that Edogawa Ranpo forced him to wear on his head - by the way, because of Edogawa Ranpo's personal interest, the clothes they wore in the two companies were the same.

As a result, other members made a lot of jokes in order to distinguish the two "Mr. Ranpo".

The cool breeze was very comfortable on the face, especially today when there was sunshine. The warm sunshine fell on the body, which blew away most of the slightly negative emotions in Shiwu.

The alias of "Ranpo Edogawa" was not designed to be immersed in negative emotions.

After leaving the house, Shi Wucai felt that his reaction at the time was a bit too much - considering Ranpo's character. Why

not go back and apologize? As Ranpo Edogawa was thinking this, he suddenly heard the sweet laughter of a child not far away.

The child walked over here, and he said in a child's unique coquettish tone:

"Come and play with me! Big brother~"

The author has something to say: Shi Wu: I am just guessing, and the reasoning is full of countless subjective ideas, and then they were led astray by me. I didn't mean it (well-behaved)
