A blizzard had raged for ten days, with temperatures plummeting to below minus fifty degrees Celsius.Yet, that wasn’t the most terrifying part. The impending disasters of rat plague, extreme heat, drought, acid rain, tornadoes, and other severe weather conditions would follow one after another, each one a veritable hell on earth.Gu Pan was reborn seven days before all these calamities began. At this time, her Space was still with her, her husband was still alive, and she needed to hoard resources like crazy.Food, clothing, shelter, transportation, medicine, weapons, electricity, and all other essentials of life—she had to stockpile enough for the next lifetime.What? The ‘friend’ who had betrayed them in the previous life was also reborn? And they had hoarded a warehouse full of supplies, even more than them? No more nonsense, just take it all into her Space.After the apocalypse began, she and her husband kicked off a spree of zero-cost acquisition.In this life, they would take revenge on their enemies and settle all scores. Those who had hurt them would be repaid double.
