A Natural Disaster Is Coming, Better Draw A Card First!

Qiao Qiao is a young woman who wakes up drenched in sweat, realizing she has returned to the day before the apocalypse. In her previous life, she survived three years of catastrophic natural disasters, only to die during a high-risk mission. Her final memories are of losing contact with her parents during the initial heavy rains and receiving news of their deaths in a hospital morgue. Upon waking, she discovers a transparent interface identifying itself as the Doomsday Card Drawing System, confirming that her traumatic experience was a premonition of reality. The system offers daily card draws with varying rarity levels, ranging from common N-rank items to powerful SSR-rank abilities. Qiao Qiao immediately claims her newbie gift pack, receiving an R-rank solar panel, and realizes she has thirty-seven remaining draw chances, matching the exact number she had at the moment of her death.

Determined to prevent the tragedy that claimed her parents' lives, Qiao Qiao quits her job in a distant city and returns home to reunite with her family. She confesses the impending doom to her parents, Qiao Xinghe and Qiao Huizhou, demonstrating the system's magic by materializing a flowerpot from a card. Convinced by her evidence, her parents join her in frantic preparations. The family liquidates assets, selling a school-district apartment to raise capital. They divide responsibilities: Qiao Xinghe uses his connections in the supermarket industry to bulk-purchase food, water, and fuel; Qiao Huizhou acquires medical supplies and clothing; and Qiao Qiao oversees home renovations. They transform their suburban residence into a fortified bunker, installing bulletproof glass, explosion-proof doors, solar panels, and smart hydroponic systems. They also stockpile decades' worth of supplies, including seeds, cat litter, and survival tools.

As the apocalypse approaches, Qiao Qiao anonymously posts warnings online about the coming gray mist disaster, which causes lung melt, a fatal respiratory condition. She also sends care packages to her college friends and childhood best friend, Li Chuxue, urging them to prepare. On the night of the doomsday, a beta version of the card-drawing system is distributed to the general population via text message. Qiao Qiao's parents both bind the system, with her mother receiving a rare SR-rank card that guarantees higher-tier draws. Meanwhile, the gray mist descends upon the city, reducing visibility and causing widespread panic. Those exposed without protection begin suffering from respiratory failure, while hospitals become overwhelmed with patients exhibiting similar symptoms.

During the early days of the apocalypse, Qiao Qiao ventures out to investigate a strange green glow in a nearby park. She discovers a juvenile mutant plant, the Phantom Willow, which the system identifies as a D-rank threat. Despite the plant's defensive capabilities and toxic catkins, Qiao Qiao defeats it using an axe and gasoline. Upon completing the mission, she receives a Strength Fruit and an SR-rank card pool ticket. The victory boosts her confidence, but the encounter leaves her bruised. Back home, her mother expresses concern over her injuries. The family settles into their fortified home, relying on their stockpiles and the system's resources to survive the initial chaos. Qiao Qiao monitors the outside world through surveillance, observing the collapse of social order as the gray mist thickens and the torrential rains begin, setting the stage for a long and difficult struggle for survival.
