Tận Thế Đại Hồng Thủy

A 49-day downpour drowns the world. A betrayed man wakes up seven days before the disaster strikes and gets an infinite backpack system which lets him hoard supplies, gold, and guns. He sees through fake smiles and builds an elite team. When the rain comes, he survives the flooded wasteland, and becomes a force no one dares to challenge.
