Bound to a Fishing Rod from the Start, I Get Rich by Fishing Across Worlds

Wan Li died alongside her younger brother, and the two of them perished together in the game world of a higher civilization. Wan Li came back to life, returning to the nightmare-like beginning of the game. Her brother's System circled her in a helpless rage, furious beyond words, and revealed the truth: this world was nothing more than an online novel. With its energy depleted, the System forcibly bound itself to Wan Li, even using up the last of its power to leave her unregistered in the game, unable to bind to a beginner's safe house. Wan Li turned the tables and unlocked a talent: the Fishing Rod of Ten Thousand Worlds. It can't crush monsters, but it's fantastic for fishing! Before long, fallen prodigies from cultivation, ancient, apocalypse, and interstellar worlds... had all become her employees. The protagonist, her brother, with a new soul in his body, wept and begged to cling to her coattails. In the end, even the higher civilization invading Blue Star had to kneel and cry, "Big Sis, I want to have your babies!"
