Xu Family in This Life

No system, no powers, no zombies I'm just an ordinary office worker The temperature keeps dropping, just before it gets completely out of control Bet all your savings to build a safe house with iron walls I don't want to be a hero, nor do I want to dominate the wasteland The most precious things in the last days are never weapons and food But a lamp, a bowl of hot porridge, and people waiting for me to go home In this cold world, my family is my only faith In this life, the Xu family will not rest until death. [Pure mortal survival, no golden fingers, slow-paced and realistic, family-oriented]
