Sister Betrayed, I Have 100x Shrink System

Long Zhenzhen reborn just before the apocalypse, driven by the resentment of her past death at her sister Long Jiajia's hands, she vows to cut ties. Rejecting the flawed expansion system, she relies on a shrinking system to craft a survival plan, purchasing energy equipment and acquiring rural land to build her exclusive base. While Long Jiajia gets lost in romance and ignores the looming crisis, Long Zhenzhen shrinks herself and hides in her base, waiting for the apocalypse to arrive, while her sister's fate quietly shifts with the coming of the end times.
