Traveling Through the Book to the End of the World: I Bound the Protagonist's System

Su Jianjian's hands were itchy recently, and she rolled up her sleeves as she looked at the system that always wanted to deceive her into making room for the protagonist as soon as possible... Hey! You've had enough of the system. I've bound my aunt, so you can run wherever you want! !
