A Family of Four Perseveres at the End of the World

"Lin Jianjun, are you crazy?" The night before the rainstorm, his neighbor kicked open the door of his house and laughed while pointing at the supplies in the house. No one believed the veteran's warnings—including his wife. Seven days later, the city was flooded. People who once laughed at him knelt at the door and kowtowed to beg for water; once arrogant strong men came to smash the door with steel pipes. And inside that double-layered steel door is the life and death struggle of a family of four. 460 Liters of water, 200 kilograms of rice, 120 cans, and a house full of medicines and tools—this was the "life-saving money" he spent all his savings on. No cheats, no system, no rebirth. There is only a high wall and four people inside the wall who are unwilling to give up. When humanity collapses in desperate situations, can they hold on to this last safe haven?
