In order to verify his guess, Dazai Osamu conducted a comprehensive investigation of this "suspected safety device", from its background to all its traces in Yokohama.

The more he investigated, the more shocked Dazai became.

This person has no past. He suddenly appeared in this world and lived his life with ease, as if he was very familiar with Yokohama, and the people and forces in Yokohama.

He even got a very important piece of information from Sister Hongye. This person once slept in the hotel without any protection, and was still hugging that shameful pillow.

This shows that he has an unusual sense of security in this city, or in some aspects of this world.

There is absolutely no way he has no connection with this place - Dazai Osamu judged this, and at the same time gradually confirmed the theory of parallel worlds.

He has always scoffed at the theory of parallel worlds. The choices that have been made cannot be changed, especially those that make him regret. He thinks he is despicable and does not hope that there will be a world where he can make the right choice, so that he can comfort himself.

However, things don’t always turn out as we wish.

That day, when Chuuya took the "suspected security device" away from the hotel, he did not take all the messy things with him, so he left the beige windbreaker behind.

When he was free, Dazai Osamu would involuntarily look back on his past memories to consider other possibilities of certain things.

He carefully treated the entire hotel room at that time, and he personally did some comparisons on the few orange hairs that were left.

Incomplete – incomplete DNA.

No matter who he is, the DNA should be intact - as long as he is a complete person.

Dazai Osamu took this list, erased all the data, and then forged two sets of paternity identification information.

He needs to know why the DNA is incomplete.

He observed the life of this outsider.

This person seems to seldom leave the safe house, but he enjoys the illusory life of this world almost crazily. Comics, novels, games, for them, are all a way of escaping from reality. He doesn't like to communicate with strangers, but he can communicate freely when necessary, which shows that he has an environment that requires him to communicate with strangers, but in his heart he is escaping from reality. He never mentions his name, perhaps because he himself does not have the answer. He never leaves any written text, nor does he leave any records of his existence. things, which may indicate that he may leave some information or clues in the text that he is unwilling to leave; he always repeats his life experience again and again, and sometimes when he is alone, he will think about something and practice unconsciously, which shows that he is not confident in his identity at all, but on the contrary, he seems to be able to convince himself quickly every time, and then imprint it on all his actions with great confidence; and he will create pain for himself very regularly and on time every day, and will feel relieved when he finds that there is no reaction.

These unconscious behaviors are the best evidence of his identity.

Dazai Osamu guessed that the word "suspected" in "suspected safety device" should be removed, and this device might be even more perfect than Chuuya. A "safety device" that has no sense of pain, weak emotions and possesses the characteristics of "disqualified from the human world" can better control "Dojian Arahato".

But at this time, Dazai could only connect "No Longer Human" with the creation of "books". Until Dostoyevsky appeared.

When Mori Ogai and Fukuzawa Yukichi were injured at the same time and were placed on both sides of the scale in a "mutual devouring" situation, Dazai Osamu knew Dostoyevsky's purpose. This person was testing the importance of these two leaders to Yokohama, their proportions in their respective organizations, and the reaction speed and combat power of each force in response to the crisis.

This is not just one event, it is the beginning of a much bigger plan.

However, at this time, Dazai Osamu did not have enough information to support his subsequent speculation, and he needed to fish out Dostoevsky.

This alien from another world would be a good bait, and it would also be a good opportunity to test the waters on another issue concerning "security devices" that was very important to him - and even if he did not actively use this alien, his information would not remain hidden in Dostoyevsky's possession for long.

Even Dazai Osamu himself admitted that Dostoevsky was definitely an evenly matched opponent of his, and an enemy that he needed to deal with with all his strength.

With the special point, it is indeed much easier to eliminate the "co-eating".

Dazai Osamu, Mori Ogai, and Fukuzawa Yukichi explained the origin of the "safety device", but at the same time concealed most of the speculations that are still difficult to confirm.

"Although it's another world, the thought of me and a little slug having a child still makes me feel super-disgusted!" Dazai Osamu turned a transparent sticker on his finger. He cut the sticker into the size of his fingertips and put it in his pocket.

“Fuck, you said it like I wanted to, you bastard Mackerel!” Chuuya was relatively restrained in front of Mori Ogai, but he couldn’t hide his murderous look. “At least that kid looks like me, which only means that my DNA is much stronger than yours!”

Men always have a desire to win in strange places.

Dazai Osamu secretly rolled his eyes in his heart. It was hard to say whether this "safety device" was naturally produced. No matter how much the father and son looked alike, they would not be exactly the same, not even having the same sensitive points.

So he is undoubtedly a child who was not brought up naturally. The problem lies in his background - although now there are various signs that his background may be inextricably linked to "books".

But Dazai Osamu knew something different, which was the obscure intelligence he had extracted from an extremely complicated incident during the days when he was whitewashing himself.

Life is the most precious thing in this world. A true soul cannot be fabricated out of thin air—not even a "book".

Dazai Osamu has never been able to find the meaning of life, so the so-called "life is precious" argument is more like a joke to him. But now it seems that this sentence is at least effective.

The prototype of that body is undoubtedly Chuuya - but the "safety device" is difficult to copy. Over the years, it's not that no one has thought of stealing Chuuya Nakahara's body information for cloning, but such behavior does not even need to be stopped because such plans have failed from the very beginning.

Because Nakahara Chuuya's identity as a security device is non-replicable, most other people can become human versions of "Dolly the Sheep" as long as they are manipulated properly.

And in the continuous trial, Dazai found that the more people he knew the outsider, the longer the time, the more often he would take the initiative to go out. It seemed that all the initial shame had been used up, and he was getting more and more comfortable.

And it is evolving in an imperceptible and subtle way.

It was difficult for others to notice, but Dazai Osamu, who was observing carefully, noticed that the person's brain and body seemed to be gradually activated.

Dazai Osamu realized that no matter what his purpose in coming to this world was, he had already integrated into this world. If he was not stopped, when his "real name" was accepted by the world, he would never be able to leave.

His daily confirmation of his physical condition, the partial concealment of his identity, and the obscurity of all his words all indicate one thing: he is slowing down the world's recognition of him, and he is trying to reject this world.

Dazai Osamu estimated that this possibility was at least 90%.

"By the way, what's the kid's name?"

"Emm - Dazai Osamu's big son." Dazai Osamu didn't even care who asked the question. He just joked and then warned seriously, "He can't have a name."

Of course, this is not because Dazai Osamu is kind enough to help others, but because this unknown element will bring unknown good or bad to the world. He needs to control the degree so that the world will not completely reject this outsider, but will not completely accept it either.

This is the safest state at present.

Moreover - although he was reluctant to admit it, this strange amusement had caused Dazai Osamu's suicide frequency to drop sharply recently.

The "safety device" of the other world has an undisguised trust in Dazai Osamu, and is wholeheartedly devoted to Nakahara Chuuya - it is difficult for him to describe what kind of feeling it is, but inexplicably sometimes he even feels a sense of kindness like an old mother, which is very strange, but also very sincere.

This kind of emotion is so precious that even Dazai Osamu does not want to destroy it easily.

He just hates himself. Born in darkness, he has a tendency to attract light whether he admits it or not.

The bait soon caught something, and Dostoevsky was hooked. He was able to produce fragments of the real "book" to verify his guess.

After listening to their conversation, Dazai Osamu stuck the transparent stickers he had prepared in advance on his fingers to avoid direct contact with the "book".

After all, this was a legendary item that he had never actually touched, so Dazai Osamu was very cautious.

Judging from all the information available so far, since Dostoevsky dared to appear before him without any scruples, it seemed that he was about to start the next stage of his plan.

Dazai Osamu specifically applied for a mission with Edogawa Ranpo, and after solving two related cases within a minute, they finalized the following plan by the widest river in Yokohama.

When it comes to all kinds of conspiracies, no matter how smart Edogawa Ranpo is, he cannot beat Dazai Osamu; but if we talk about reasoning based on the existing clues, Dazai Osamu also admits that he is not as good as Edogawa Ranpo.

The sorted data was placed in front of Ranpo Edogawa, and the emerald eyes behind the glasses of this older boy were filled with shock.

"Dazai, you already have the answer, right?" Edogawa Ranpo took out the fragment of the "book" from Dazai's pocket.

"It's just a guess."

Edogawa Ranpo hooked his fingers and asked Dazai to take the pen. "Your reasoning is mostly correct - he has the shadow of Hat-kun and you on him, and your traces are engraved from body to soul. You in another world may have taken the lead, but he is the one who makes the final decision. He came to this world to do something, or to save something -"

Ranpo paused for a moment and looked at him seriously, "Dazai, do you regret something so much that you want to go back and change it?"

“……” Dazai Osamu didn’t say anything.

"The extreme regret is to the point where I would change everything in another world, even if it was just to prevent myself in another world from experiencing these things. Even though doing so much would not change the outcome of my own world, would not make me happier, I still want to seek comfort in my heart." Ranpo Edogawa has made it clear enough at this point.

Dazai Osamu finally confirmed reluctantly that the visitor from another world was not his and Chuuya's child at all. He trusted himself because they had been through life and death together, and his sympathy for Chuuya was a reflection of his regret.

"That person" may have created a virtual spiritual world to numb himself, but what is truly unchangeable can never be changed.

He is not Chuuya's "Dolly", he is Chuuya's projection, he is Nakahara Chuuya himself.

Edogawa Ranpo's pen tip landed on the paper, "He just wants to become the current Chuuya."
