   This one is also great, though I don't know why nobody seems to read it. There's no female lead, no romantic pairing, and the protagonist is Changsheng, who seems to have lived from the Tang Dynasty to the present. He's the kind of person who's cold on the outside but warm on the inside. If you want to ship him with someone, I think he and Captain Lu (the criminal investigation captain) would be a good match. Mainly, Officer Tang (the protagonist) has a very high rank, so you might understand that unintentional air of swagger. Also, you can tell the author did their research before writing; the professional knowledge was amazing! The teammates in the police station are also very friendly, and the characters are vividly portrayed. Each of the guys in the criminal investigation team has their own unique personality [I'm so full][I'm so full][I'm so full]. Anyway, it's definitely worth reading! It's really good!!

   This series absolutely has to include Mu Guang, you can tell from the name. It's definitely top 1 on my reading list. Our Mu Guang is incredibly beautiful, strong, and tragically miserable—of course, the misery refers to her physical condition, and everyone around her cares about her. No romantic partner, even her superiors are very concerned about their subordinate. She also has a blood clotting disorder and a whole host of other minor ailments—no, major ones! Later on, she even injures her wrist. Of course, things weren't much better in the beginning. But there's one downside: the updates are too slow. I waited half a year and only got about 50 chapters. But it's definitely worth investing in, it's very good. Three chapters a month is considered good. The next two books aren't about an undercover agent returning—well, they're also very good, they're crime dramas by the same author, very sweet, extremely sweet, incredibly, incredibly good, not a single angst [laughs]. Trust me. The fourth book, I read it a long time ago, I've forgotten a bit, I think the protagonist died? Then he travels ten years into the future, and he's not in his original body anymore, I've forgotten a bit, anyway, they're all pretty good, you should check them out.

    The first book is quite heart-wrenching; the two characters are a perfect match, but it feels a bit too tragic.

The second book isn't exactly about infiltration, but the protagonist is incredibly smart and knowledgeable. His meticulous plans are things that most people wouldn't think of.

    These books are all quite good, falling into the undercover/military genre. The last one, in particular, breaks the usual trope of the protagonist returning safely surrounded by a halo of glory; it's really excellent. While reading it, tears streamed down my face ( •̥́ ˍ •̀ू ). In reality, we mostly witness their glory and honor, but it's hard to imagine the pain and helplessness behind it all.
