Apocalypse: I Have A Multiplier System

In a post-apocalyptic world where humanity adapts to a harsh new environment, Su Jiayi endures a miserable existence with her foster family. Facing threats from her foster mother, cousins, and foster father, her life takes a turn when she is forced into the Army instead of her foster sibling. Severing ties, she joins the ranks, fighting zombies barehanded due to her lack of superpowers. Near death during a zombie encounter, Su Jiayi accidentally triggers a mysterious system and claims ownership of a hidden location. This grants her both a sanctuary and a powerful multiplier system. She gains infinite vending machines and deluxe rooms, which she leverages to establish a thriving residential area and grocery store. Her ventures quickly gain popularity, attracting customers from afar. When her estranged foster parents seek her aid, she rejects them. Meanwhile, the captain of the Willow Army, whom she harbors a crush on, views her with admiration, unaware of her true identity. The novel promises a rapid start for its initial chapters, with the main narrative unfolding after chapter twenty.
