Ye Jin, a top-ranked Tri-elemental ability user in the Southern Base, is betrayed by her cousin Yu Ruanruan and her lover Fu Yihao five years into the apocalypse. They forcibly extract her Nucleus Crystals, revealing that Yu Ruanruan coveted her powers and the dimension hidden within Ye Jin's family jade pendant. Yu Ruanruan also confesses that she orchestrated the death of Ye Jin's younger brother, Xiao Chen, to eliminate a witness. Betrayed and left for dead in a warehouse infested with zombies, Ye Jin dies with her heart full of vengeance. Upon opening her eyes, she finds herself reborn two months before the apocalypse begins, back in her university dormitory. She realizes she is a cannon fodder supporting character in a Mary Sue novel, destined to have her abilities and resources stolen by the female protagonist, Yu Ruanruan. Determined to change her fate, Ye Jin immediately activates the dimension within her jade pendant, discovering it contains a spirit spring, cultivation manuals, and a time-dilated space for storing supplies and living creatures. She undergoes a marrow-cleansing ritual using the spirit water, significantly enhancing her physical strength and awakening her Thunder ability ahead of schedule. Ye Jin begins liquidating her assets, selling her properties and jewelry to amass a fortune while secretly stockpiling massive quantities of food, water, weapons, and livestock in her dimension. She also enrolls her younger brother, Yu Zichen, in martial arts training to prepare him for the coming disaster. During her preparations, Ye Jin encounters Gu Jingzheng, a special ops captain who has also awakened abilities early. He is being hunted by a rival faction, and their brief interaction reveals that others are aware of the impending changes. Ye Jin then confronts her uncle, Yu Zhenguo, and cousin, Yu Leyang, who are scheming to steal her parents' company shares. She outmaneuvers them by pretending to have already sold the shares to a third party, forcing them to pay a hefty penalty to retrieve them, thereby securing more funds for her survival preparations. As the apocalypse draws nearer, Ye Jin continues to fortify her villa and gather resources, fully aware that she must rely on her own strength and the secrets of her dimension to survive the chaos and exact revenge on those who wronged her in her past life.
