Bind to the Strange Fairy, and the Demon Will Live Forever Together

I am the number one female detective in the Six Doors, and I have never been afraid of anyone when investigating crimes. Until that night, I found a red coffin in Blood Coffin Village and met the strange fairy in the coffin. His clothes were as white as snow, and he was cold and noble: "Mortal, you will be lucky to spend three lifetimes with me." I took out my badge: "Stop talking nonsense, help me solve seven murder cases, catch nine monsters, and complete the KPI first." Later—— He helped me with my autopsy, blocked my knife, and accompanied me to the mountains and forests to catch monsters. Later, he blocked me in a corner and said in a low voice: "We need a Taoist companion to overcome the tribulation, do you think I should be accepted?" I looked at the crime report written by him, and thought to myself: This ghost husband looks pretty good.
