[The end of the world + double life + space + hoarding + sisters + no male protagonist] Shi Wan has lived in the apocalypse for ten years and finally secured his position as the second-in-command of the First Base. Seeing that good times are coming, he never thought that his sister, who is obsessed with love, would give all her life-saving cards to the scumbag! The scumbag broke her kneecaps and made her watch her sister die among the zombies. Finally, he used the ghost vine she had raised to kill her! After being reborn, Shi Wan decided to change her destiny against the will of heaven. She started by objecting to her sister being with a scumbag! "Xiaoxue, I love you, will you marry me?" "Song Yuxuan, I'm tired of playing around. From now on, you're out!" Shi Xue rejected the scumbag's proposal coldly and arrogantly, and turned around and fell into Shi Wan's arms. Shi Wan: "???" What is going on? Now that my sister has recognized the true face of the scumbag, she doesn't need to be polite. She kicks the scumbag, kills enemies with her hands, awakens space powers, hoards supplies crazily, and kills zombies to upgrade her powers. In this life, Shi Wan will live a comfortable and nourishing life even in the last days!
