After Xu Ning dies, she transmigrates into a period novel as a newly graduated trainee police officer.
On her first night after arriving, she hears someone gossiping right beside her
"Hey, when do you think they'll find the head in the fridge next door?"
"Probably not until the power goes out. Once the freezer stops cooling, the head will start to stink, and someone will find it when the smell gets bad enough."
As soon as the unknown speaker finishes, the power suddenly goes out all along the street.
The next morning, Xu Ning wakes to a faint smell of decay.
On the third day, the landlord opens the big iron gate next door and finds the tenant's head inside the fridge, which stopped working because of the power outage.
Just then, a cat walks past Xu Ning
"I told you they'd find it eventually. It's a pity the killer cleaned up the crime scene. The police won't find any clues, either."
Xu Ning grabs the cat by the tail. "Did you see the killer?"
The cat is horrified. "Meow! A human can understand me!"

Cheng Wangzhou's first impression of Xu Ning is: "This girl is so weird. How did she get into police academy? I'd better keep an eye on her."
Later, Cheng Wangzhou sees Xu Ning following a mouse, which leads her straight to the victim's remains.
His fingers tremble as he points at it. "Don't tell me that mouse led you here?"
Later still, on their wedding night, the big, fat cat Xu Ning raised keeps scratching at the door, making a terrible racket!
Cheng Wangzhou, not even dressed, opens the door and grabs the cat, ready to throw it out. Xu Ning snatches it from his hands just in time.
The cat raises a paw to cover its eyes. "Meow! Human! I'm a boy, but that doesn't mean your husband can get fresh with me!"
Jiang Rui: "..."
"The cat came to report a case to me!"
Cheng Wangzhou: "..."
