Every Time I Open a Door, I End Up at a Crime Scene

After retiring, Luo Jingyao, a former international Sanda champion, returned to her hometown and opened a flower shop with the savings she had accumulated over the years. She was cheerful and warmhearted, and quickly adapted to her new life. But Luo Jingyao had a secret no one knew: she had a door that could take her anywhere. Unlike the golden finger door in novels that lets the protagonist make a fortune, every time this door opened, it randomly sent her soul to a crime scene. Murder by ghost, divine punishment, vampire murder, a blood-soaked house, a heart-stealing case... At last, after being forced through the door once again, Luo Jingyao smelled a faint trace of blood in the air and, on the verge of tears, turned to stare at the Tian City Public Security Bureau across the road. The Special Cases Investigation Unit of the Tian City Public Security Bureau had always been renowned, a guardian of the city in the eyes of the media and the public. Unfortunately, these "guardians" had been having a rough time lately. When Lin Jiafan, head of the Special Cases Investigation Unit, returned from a business trip, he was greeted by his team members' green faces and grimaces of pain. Through the team's resentful stares, the fitness coach the bureau had just hired clasped her hands in greeting. The dimples on her cheeks were just visible. Not long afterward, however, the physically battered "guardians" suddenly realized that somehow, they had begun living a dream life in which they could discover new evidence at any time and bump into suspects every time they went out. One day, a member of the Special Investigation Unit accidentally saw Lin Jiafan cornering Luo Jingyao in a hallway. Then a hesitant but clear female voice came from the empty corridor: "This isn't appropriate between us... You know I tend to hit too hard." The next second, the team member heard Lin Jiafan answer nonchalantly, "What's there to be afraid of? I'm willing. I'm tough as nails." As if he'd stumbled on some earth-shattering secret, the team member dashed back to the office. "We're doomed! The chief and Coach Luo are really together! And the chief is the one underneath!" Lin Jiafan had just asked Luo Jingyao to help him recreate a crime scene and happened to be walking past the door: ...???? Male lead: refined on the surface, but actually old (cunning), calculating (full of schemes), and devious (tricks galore) VS female lead: gentle on the surface, but actually brave (one), fierce (fist), and unbeatable (by anyone) Tips: 1. This is a fictional crime-investigation anthology, not a realistic one. It has mountains of invented details and a very loose setting, so please don't nitpick. 2. Prosperity, democracy, civility, harmony, freedom, equality, justice, rule of law, patriotism, dedication, integrity, and friendship. 3.
