When a worldwide disaster strikes—solar flares send the planet into an era of extreme heat, melting glaciers and evaporating rivers, while toxic rain at night further poisons all water sources—human civilization faces its end. Jiang Chen, betrayed and slaughtered for food by his girlfriend’s family in a previous lifetime, is reborn with memories and a ruthless attitude. He awakens spatial powers that let him stockpile massive supplies and create a perfect safehouse. As others suffer and roast outside, Jiang Chen lounges in cool comfort, eating ice cream and watching chaos unfold. He uses his powers to settle grudges, take revenge on his ex, and amass wealth and survival resources. Women flock to him; enemies fall; through shrewd preparation, Jiang Chen goes from survivalist to king in a ruined world.
