I recommend the novel I Can Turn You into an NPC to you! The protagonist transmigrated to a low-level martial world and obtained a world upgrade system that could turn the target into an NPC, an experience monster, or even an item that could be added. He decided that he was the protagonist and started to stir up trouble crazily. You came to the slaughterhouse and turned the pigs into experience monsters. Then, you killed four of them in a row and finally leveled up! [The Lady Boss gifted you a set of pig kidneys. You have converted the pig kidneys into an item that can be added with points. You have added points to the pig kidneys continuously. The quality of the pig kidneys has increased, and it has become a Dragon Pig Kidney!] Welcome to this infinite novel! I hope you like this fairy's recommendation. Muah ~😗
