I just realized that even though I recommended your story to my readers and have been following it practically since you published the first chapter, I have never commented. Well we have to change that, I am obviously an avid fan of crossovers and television series, your story meets both of my checkboxes. A long time ago when I started reading Chinese novels I came across this genre of crossover and since then I have been waiting for well written and interesting novels similar to them, your novel is one of these novels that I have been waiting for, it explores the interesting world of police dramas which I love. If I had to point out something that seems like a bad decision to me, it is writing in another language and then magically giving the translation without explanation for the world of your story, I always advocate immersion in stories and in this case suddenly reading one paragraph in another language to then read what was written in a language that I understand, takes away the immersion of the situation, what I could recommend in this case is to use a character to serve as a translator when it is necessary and when not (when only the MC is speaking with another person in another language) simply continue writing in English but making it clear that they are really "speaking" in another language, but that's just a recommendation you can do whatever you want it's your story. Your work is excellent and I look forward to reading much more, good luck :D
