Transmigrating into Detective Conan: The Cool and Clueless Erguotou

The protagonist is named Lin Ziye, and his codename is Erguotou. He’s from the Dragon Kingdom, so his codename is a Dragon Kingdom liquor 【a joke to save my life】 No female lead. The System is the protagonist’s younger brother, who is still in high school. The System personally completes its own missions. This is not a two-male-lead story, and there’s nothing gay or bl-like about it. There are no pairings. If you want to ship them, there’s nothing I can do about it. I’m bad at writing blurbs (iДi). The author is terrible at naming things, so if you can, suggest a good name in the chapter comments. (Come on in and have a look~)
