Bound to a Crime System, I Solve Cases by Scoring Secondhand Bargains

A daredevil female detective is transported into Xie Zhiyi's body, bringing along evidence from a crime scene.

This unlucky heiress had been literally smothered to death by her affectionate older brothers on the very first day she met her birth family.

She came to just before they put her in the cremator.

But the System assigned her a mission and sent her a link to a piece of evidence. She had to accept the job and complete the mission, or be erased.

Once she accepted, the System took her to the scene.

When she dug up a female corpse with bows tied around both her hands and feet, she was completely stunned.

The victim's family happened to show up, so she was arrested and taken to the police station as a suspect.

But since she had no opportunity to commit the crime, the captain had no choice but to let her go for the time being.

Xie Zhiyi planned to work with the police. She said she could obtain the victim's evidence and talk to it.

At first, everyone at the station thought she was crazy. But when she really produced the evidence, they were all dumbfounded.

After a winding investigation that followed the clues, they tracked down the serial killer.

"Be careful! If you run into the killer, don't fight back. Hide and wait for us!"

"Ha! What's a handful of thugs to me? I can twist them into pretzels!"

And so Xie Zhiyi became not only the family's cherished second daughter, but also the police station's favorite.

After that, every piece of evidence she bought on secondhand marketplaces became the key to solving a case.
