Ember Rebirth Final Bunker

In 2789, moments before the world collapses, Leo gets a second chance at life. He ends his engagement to a fiancée who cares more about money than him, mortgages his property to build a climate-controlled bunker, and quietly empties a rival's billion-dollar logistics port to store food for the coming disaster. When the apocalypse arrives, his fighting skill keeps rioters at bay, and he sets out to settle scores with Richard and Sarah, the enemies who wronged him. The story follows his rise from survivor to ruler of a broken world.
