This was written and played by someone out of boredom. In fact, it is an ancient imaginary. It is not a fan creation. It's just that someone was too lazy to name the characters, so he replaced them with characters from Conan. So does this become a fan again?
While I was not sure whether it was Xinlan or Kuailan, I came up with an idea... Ah... Perfect Xinlan text!
(Ps: Maybe you have read this article from the author Nuanyan·Jiuling. I want to declare that the blue fish is Nuanyan·Jiuling!)
