I raised the evil spirit and became an evil investigator

Five years ago, an evil attack left Aicheng Hualian seriously injured. When she was on the verge of death, she signed a contract with the young of the evil god and survived as the evil god's breeder.
In order to raise the evil spirit, she became a private evil investigator and accepted commissions to eliminate evil spirits.
"This investigator asks for very little reward, but her request is also very strange. She is only willing to eliminate those evil spirits that are large in size." (Good review)
"Miss Investigator does her job neatly and efficiently, but after she leaves, there is always some black-blue gelatinous substance on the ground, twisting like a snake. Maybe it's evil blood." (Good review)
"Other investigators would need several days to clean up the bodies of evil spirits. But after this investigator completed the commission, all the evil spirits disappeared like air. He is simply a scavenger of evil spirits!" (Good review)
"Strange... I once saw the investigator spit out something like tentacles from her mouth..." (This comment has been deleted)
Relying on the power of the evil god, a commission that was like dancing on the edge of a knife in the eyes of others was just three meals a day for her, easy and comfortable.
Until one day, the evil god appeared in the form of a girl with black hair and blue eyes and pressed her onto the bed.
She was shocked: "I treat you as a comrade, and you actually want to have sex with me."
