Speaking of which, in fact, Reimu was not very sure about his blind cat touching a dead mouse, but he had no choice but to choose such a barely feasible path.

The man who called himself a soothsayer was called Yi Zhe, and he was a decent resident, but as he himself said, because of his "evil" appearance, he was not very well received by the people here.

The result of divination is obviously a failure, not because of the lack of ability of the changer, but because for the person who does not exist, no matter how divination is, there can be no answer.

Reimu was disappointed, but fortunately she didn't have much hope in the first place.

However, although the divination of the Yi was fruitless, this move brought many unexpected gains to Reimu.

Especially when she said something about Takeya to Yi Zhi, and the "mutation" that happened now that no one except her could remember Takeya's existence.

Yi Zhi didn't directly think that Reimu was oversleeping or something else, like the others, he calmly analyzed Reimu from a realistic point of view.

"Memory...... Although I am not very knowledgeable in front of youkai-sama, I think it is a bit arbitrary to simply attribute everything to your own 'fantasies' of Miko-sama. ”

Listening to Yi Zhi's words, Reimu nodded silently, although this guy is not likable, but he can indeed speak.

"Hypothetical, just hypothetical—"

After comforting Reimu a little and expressing his position, Yi Zhi began to cut to the chase: "Let's assume that the character 'Takasaka Takeya' exists, at least it exists, but it has disappeared into other people's memories for some reason, so that the target that needs to be investigated is very clear." ”

"What is it?" Reimu asked impatiently.

"Spirit."

The summary of this one word is the answer given by Yi Zhi, and he patiently explained to Reimu with a puzzled face: "We assume that 'Takasaka Takeya' exists, but if his traces have been completely erased from this world, then no one will remember him." ”

Reimu frowned and said dissatisfiedly, "But I remember." ”

"That's right," Yi Zhi nodded at Reimu and continued, "Since Miko-sama still remembers his existence, it means that his traces in this world have not been completely erased, so since you can remember, naturally others can also remember." ”

“...... Go on. ”

"Mikome-sama, you must know that the so-called memory is actually an extremely ambiguous thing, and the forgotten part does not mean that it will disappear directly, it is likely that it is only disturbed by external forces, making it stay in an imperceptible corner or simply hidden."

Looking at the Lingmeng who was gradually absorbed in listening, the corners of Yi Zhi's mouth showed a subtle arc: "If that person really exists, even if everyone's memories have the possibility of being manipulated, then there must be exceptions, such as you, and for example-some individuals who have a vague concept of memory from the beginning. ”

"You mean, Spirit?" Reimu's eyes lit up: "Undead? ”

"Exactly." Yi nodded in agreement.

Yi's words inspired Reimu, if Wu also really existed, but everyone's memories were passive, then if you want to find the fish that slipped through the net, you must work hard from the group whose memory is not easy to manipulate.

The spirit body is the best choice, without the constraints of the body, the memory of the spirit will not be limited by the body, but will become a symbiosis like the spirit, and want to erase the memory of the spirit, which is almost no different from directly destroying them.

On the other hand, as long as it is a living soul, the memories it has must be closely related to the time of death, or it is very difficult to erase.

However, there are many spirits in Gensokyo, but there is undoubtedly only one that has the closest relationship with "Takasaka Takeya".

"Thank you!" This Xie Lingmeng said from the bottom of her heart, she didn't stop for almost a moment, and flew straight towards the end of the sky in the extreme east, where there was the gate of Gensukyo's connection to the underworld-Netherworld Enchantment.

The Yi who stayed in place just watched Reimu's departure, and it wasn't until the other party's figure completely disappeared from sight that he slowly took out a pen and paper and recorded what Reimu had inadvertently said just now, about the existence of "Takasaka Takeya".

"'Takeya Takasaka', if such a character really exists......"

Carefully jolding down everything related to the forgotten name, a long-brewing darkness slowly emerged in Yi's eyes, which were obscured by round lenses.

......

Underworld, White Jade Tower.

As an undead, there is actually no difference between sleeping at night and not sleeping, but although Yuyuko has not been able to inherit the memories of being a human, she has inherited the habits of being a human.

So at night, she was struggling with mountains of food in her dreams, and the anger of being woken up by a riot can be imagined.

"Reimu?"

At first glance, when she saw this guy who came to make trouble, Yuyuko subconsciously wanted to avoid it, she and the Hakurei witch were not strangers, but they were not familiar enough to be called friends.

I remember the last time we met, it was this guy who came to hinder his collection of the "Spring" plan, so that not only did there be no old love between the two, but there was no new grudge that was not settled.

"It's good you're awake."

Reimu didn't disturb Qingmeng's consciousness at all, and the words she said were also very hateful, but now she didn't care about it.

The first time she saw Yuyuko, a strange memory suddenly appeared in front of her eyes.

In that memory, I didn't come to the underworld because of Takeya and Sakuya's request to look for Purple's traces, but to solve a strange "Spring Snow Mutation"?

All the details of the memory seem to be reasonable, as if he had experienced it himself, but there is only one thing that is strange, and that is that in this memory, there is no Takeya.

Two completely different memories of her journey to the underworld intertwined and twisted in Reimu's mind, messing up the past she had managed to sort out, and vaguely, the traces of Takeya's existence seemed to fade in her memory.

You have to hurry, or it's going to be too late!

When he realized that his memories were also erasing the traces of Takeya little by little, Reimu was no longer willing to wait for a moment.

"Undead, I have something to ask you." The intense fear of the fading memories made Reimu's mood suddenly turn terrible, and even her tone became very irritable for a while.

"Huh?" Yuyuko raised her eyebrows, although she is a good-tempered monster in Gensokyo, but she was disturbed by the people's dream at night, and she was questioned by such an inexplicable teacher, no matter how she thinks, she can't treat it calmly.

In addition, this time there were no small actions that Yakumo Purple was doing in secret, and for this uninvited Hakurei witch, she also had the idea of teaching the other party a good lesson at this moment.
