When the doomsday descended, Su Qing was locked outside the door by her ex-husband Chen Hao in her past life, watching helplessly as he used the 3.8 million obtained from selling her house to purchase supermarket supplies, sharing survival resources exclusively with the third party Lin Weiwei, and ultimately dying a tragic death outside the door. Reborn to three days before the outbreak of doomsday, Su Qing accidentally awakened a portable space where items can be stored and retrieved within a three-meter range, but cannot store living people or architectural components. In this life, she suppressed her anger of revenge, feigned obedience to Chen Hao, utilized his trust, and step by step, quietly emptied the entire supermarket inventory he purchased with a huge investment.
