In her previous life, Jiang Yan's mother was murdered by her stepfather under the guise of celebrating their wedding anniversary with a trip abroad, and Jiang Yan herself, holding a huge inheritance, was locked by him in the basement of a villa and had one of her hands mangled. As natural disasters became more frequent and the apocalypse descended, the stepfather's family, hiding in the villa waiting for the apocalypse to pass, ultimately set their sights on Jiang Yan...With the opening of her eyes, Jiang Yan was reborn three months before the apocalypse. After activating her portable Space and successfully taking her revenge, she, now in possession of a massive amount of funds, started a global shopping spree: yachts, helicopters, off-road RVs, weapons, amphibious boats, necessities for clothing, food, shelter, and transport; everything from five-star delicacies to tasty street food hidden in remote corners... she bought and hoarded them all, bringing everything into her Space!Seeing that there was only one month left, Jiang Yan began a cramming-style learning binge: shooting! Flying planes! Driving boats! Hand-to-hand combat! Agricultural Planting! She even learned how to operate an excavator from the Red Xiang Technical School!In July, a double typhoon that caused seawater backflow starting from Japan marked the beginning of the apocalypse. A super high temperature wave followed right after, sweeping across the globe, along with torrential rains, earthquakes, pest infestations, extreme cold, nuclear contamination, mutation of animals and plants... one natural calamity after another ensued!While others fought over a packet of instant noodles or half a bottle of water, Jiang Yan was leisurely planting vegetables, raising fish, sitting comfortably in her safe house with air conditioning on, and enjoying her hot pot meal~PS. This entire story is fictitious.
