I recommend Supernatural Resurrection! I'm a Rebel and Mysterious Revival: I Can Create Supernatural Items. They were both mystery detective novels. The story of "I'm the Rebel" was about the protagonist who had a special physique and protected humans in a parallel world to form a supernatural bureau. The story of "Mysterious Recovery: I Can Create Supernatural Items" was about the protagonist stealing the power of ghosts to create supernatural items and becoming the largest wholesaler of supernatural items. They were full of mystery and thrills, very suitable for readers who liked horror novels and supernatural literature. I hope you like this fairy's recommendation. Muah ~😗
