In the second case, I think you can refer to the following methods to protect yourself.
1: Avoid and try not to appear in Conan's field of vision.
As the saying goes, "If you can't afford it, you can't afford to hide." Since everyone knows that Conan is coming home one day in advance, at least there is enough time to prepare for you. I don't want to be influenced by his special aura. In fact, the simplest and most effective way is to stay away from him completely, don't appear in his field of vision, and don't let him be interested or concerned about you. We can infer from Conan's cartoon1119 that about 85% of the victims and prisoners will be captured in advance by Conan's magical "sixth sense", so how to avoid Conan's "sixth sense" is the key you have to face.
2. Prepare "Keke" food at home: raisins and garlic.
Of course, if you don't want to escape or "escape is inevitable" for some special reasons, there is another way to minimize Conan's time with you, and it is best to let him dispel his interest in coming to your home in advance.
Here, I personally suggest preparing some foods to drive Ke away at home, such as raisins and garlic, because both of them are unacceptable to Conan, which are stated in the chapters of Conan's TV version of Memories of Cherry Blossom Class and Lovers Disappeared in the Snow, so prepare these foods at home in advance and let Conan know in advance. I think it can effectively dispel Conan's desire to come to your home, thus avoiding the influence of his special aura.
3. Find a way to join the "Junior Detective Team"
When the current two active attacks can not be successfully realized, then the "passive" defense is left. In this respect, we can refer to * * * homosexuality in Conan 1000 to seek self-protection.
For example, joining the "juvenile detective team" and becoming one of them is the "bear" children's team that is rejected by many people. Although they make a fool of themselves in the play, all kinds of people are worried, but it is undeniable that the members of the juvenile detective team (including teachers), although they encounter many things, often end in success. Maybe Conan's so-called aura is in the child.
Perhaps this is the real reason why Mr. Qingshan wants to build a juvenile detective team. In addition to dragging the plot, he just wants to use the innocence of the child to suppress the negative caused by the suspense of reasoning.
4. Get the certification of "Lan" angel love.
In addition, there is the kindness certification of the heroine Mao Lilan. Let's just say that the role of a good man recognized by Lan will basically not be visited by accidents. Even as a prisoner, I have always had the idea that G?sh? Aoyama arranged an "angel" aura on Conan (Kudou Shinichi), but arranged an opposite "angel" attribute neutralization on his childhood friend Mao Lilan. This is called destiny takes a hand.
5: Direct refusal
I almost forgot one thing. If you can ignore politeness, the most direct way is to call and cancel the meeting. After all, it is better to cancel this risky meeting as soon as possible.
Summary:
Finally, I want to emphasize that whether you welcome him to your home or not, don't reveal the fact that you already know that he is Kudou Shinichi. I know that many people on the Internet suggest to protect themselves by "exposing their identity into the main line", but this is the most wrong and irrational way. I can tell you clearly here that if you are not a "superhero" like Akai Shuuichi, Antou and Kudou Yū saku, you can enter at will.
The same type, such as informing Gin, belongs to the decision to let yourself out in advance.
