Zhang Ran was reborn with the memory of his tragic death three years after the end of the world, returned to the three days before the disaster, and awakened the omnipotent proficiency system. Cooking, making fire, firearms, fighting, manufacturing, and medical skills, you can brush up your proficiency by just doing it, and rise to the master level all the way. While others were freezing and hungry, wailing in the ice and snow, fighting each other for food, he bound to the eternal safe house, stocked up tens of billions of supplies, and hid at home to quietly master all his skills. Mob siege? The Grandmaster sniped Qianli for roll call. Mutated ferocious beasts appear? Full level fighting is directly pushed horizontally. When the whole world was still fighting for a piece of dry food, Zhang Ran guarded the constant-temperature fortress, barbecued and drank wine, and with the strength of an almighty master, he crushed all forces and dominated the entire frozen apocalypse.
