I Turned the Villain into the Police Force's Secret Weapon [Crime Investigation]

Jiang Xia transmigrated into a book. She landed in a period novel called "City Ablaze with Sin," created by someone grieving after her boss died in the line of duty. In this story, her boss's younger brother, Pei Anbai, hadn't died young. Instead, after his older brother was brutally murdered in revenge, he turned dark. He wiped out a criminal gang using extremely cruel methods and became a villainous BOSS whom no one could handle. That's the novel she transmigrated into. But... nobody told her that. After all, the moment she opened her eyes, she discovered she'd become a bird and was bound to a crime-solving reward System. Thinking she'd been handed a crime drama script, she worked tirelessly to solve cases every day so she could turn back into a human as soon as possible. She also found herself an amazing partner. The woman and bird worked seamlessly together, becoming the police team's best secret weapon. Although sometimes this partner seemed even more villainous than the actual villain, she had no idea he'd really become a villain in the future. If she'd known, she definitely wouldn't have dared to act so outrageously around him. * "Pei Anbai, I'm thirsty. Pour me a glass of water. Make sure it's clean." Pei Anbai: ... He said nothing, but did it anyway. * "Pei Anbai, you're not the murderer. Could you stop saying creepy things like that and just send him to prison already?" Pei Anbai: ... He said nothing, but did it anyway. * "Pei Anbai, I think I'm getting more and more outrageous. It must be because you've corrupted me." Pei Anbai: "Heh..." Jiang Xia: ...smiles. Pei Anbai said nothing. He silenced her with a kiss, then murmured in her ear as her legs went weak, "See? This is how I corrupt you." Jiang Xia silently gritted her teeth, but her face still turned red. Theme: Stand up for justice and protect the light
