Zhang Miao was reborn and returned to three days before the end of the world. In her last life, she hated her father for hoarding goods and was eventually betrayed in the sweltering heat; in this life, she decisively ran towards her father who had transformed his basement into a fortress. Not only do they have to face extreme weather, but they also have to resist the greed of their neighbors, the revenge of their ex-boyfriends, and even brutal armed groups. When everything seemed to be over, a mysterious man who was also reborn appeared, revealing another guardianship that spanned two lives and bringing them new hope atop the ruins.
