When a nuclear bomb exploded in the clouds, no one expected that it would tear apart not only the sky, but also a fat man's path to counterattack. Li Xiao traveled through time, and lived a prosperous life in the wasteland with the memories of his previous life and a body of fat. He is not a hero, but he is always put on the altar; he seems to be lustful and brainless, but in fact he is cautious at every step. In this world where zombies are rampant and order has collapsed, he uses a crowbar to move fate and deceives everyone's eyes with a smiling face. He struggled to survive in the ruins, and could not even find a sip of clean water; he quietly laid out his plans, won over people's hearts as a "weak", subdued powerful generals, and diverted trouble to the east; he stood on a high tower, with his iron-blooded brothers and confidante behind him, but in front of him was human civilization riddled with holes. But when he finally unified the world and reestablished order, a question followed him closely: When the doomsday reshapes humanity, does humanity still deserve a tomorrow?
