Port Detective Agency

"Want to time travel? The benefits are great." "No, thank you" "No, you want" (One about the forced selling of the system???) "This is what you call super benefits." "Isn't it good? Baby Mo Xin~" "It's really great" [Well, the author hasn't watched Conan very much. I should be able to read and write now. That's it. As for this book, it is the first book the author has published online. There is no manuscript. If I have inspiration, I will write it. The protagonist may be a black mud, maybe not, but his character is the kind of person who wants to commit suicide but dare not, well, that's it.]
