I Just Slaughtered a Whole Village with Fire, Why Is It Hopeless?

Looking for a Detective Novel Like Forensic Doctor Qin Ming! !

One case after another, don't fall in love! Don't fall in love! Don't fall in love! Say important things three times! Wouldn't it be nice to solve the case well? That little brother and sister have some, please recommend them. 🥳🥳🥳
