My Family Wants Me to Pay Their Debts? I'll Send Them All to Prison

[No catfights between the real and fake heiresses, strong heroine, a touch of the supernatural, mystery-solving, no romance] Si Qingming had been dogged by bad luck since childhood. Then, out of nowhere, she went from being a wealthy heiress to a fake one and was sent back to her birth family. And wouldn't you know it, every last one of them was a piece of work, a bona fide villain! No matter. She had a bad-luck rebound buff. Anyone who messed with her would have rotten luck! After she returned to her birth family, a bout of rhinitis and fever made her nose act strangely. When other people sneezed three times, it meant someone was thinking about them or cursing them. When she sneezed three times, someone had died! The stench of a corpse coming through the crack in the neighbor's door? The neighbor was inside a sealed bag in the fridge... A mystery delivery box that reeked of a corpse... The stench of a corpse on her older brother was getting stronger... Her stepmother smelled not only of corpses, but of blood, too! Call the police! Call the police for all of it! From then on, she became an unofficial “sniffer dog” for the town police station. Whenever she sneezed, the station chief and the officers would stare at her with shining eyes, yearning to meet their quotas. Si Qingming: “Why are you all looking at me like that?” “Nothing... We just wanted to ask what you've smelled this time.” Just as Si Qingming was making a name for herself at police stations all over the place, her wealthy family suddenly showed up. “Qingqing! Grandma's gone missing. We can't find her anywhere. She loves you most of all. Could you help us look for her...?” Si Qingming stared at them in bewilderment. “??? Do you hear yourselves? If someone goes missing, call the police!”
