I Can Turn You Into An NPC

You transmigrate to a parallel world where everyone cultivates their body. You gain the ability to turn targets into NPCs, experience monsters, and even items that can be leveled up. Convinced you're the main character, you start to go crazy (posing) with (cool) things. You turn your sister into a quest NPC, and she gives you a quest: cook, mop the floor, and scrub the toilet! You go to the slaughterhouse and turn the caged pigs into experience monsters, then kill four in a row, finally leveling up! The landlady gives you a pair of pig kidneys, which you convert into a level-up item. You continuously level up the pig kidneys.
