Lin Weiwei and Nan Jin suffered betrayal in the previous end times, being killed by the scumbag Jiang Hui and roommate Lu Jiayan. Fortunately, both of them are reborn, returning to one month before the arrival of the end times. In this life, they are no longer weak, cleverly seizing the scumbag's Fish-Yu Jade Pendant at the graduation banquet, unlocking a dual-attribute space possessing planting and time-stagnation abilities. The two seize the time to hoard massive supplies, heavily reinforcing their villa fortress, purchasing self-defense weapons through special channels, and unexpectedly discovering that books can be used as energy to upgrade the space. The sisters plot step by step, making thorough preparations for the upcoming doomsday heavy rain.
