Reborn: The Apocalypse Lord

In her past life, Summer Hall was betrayed and died. Brought back to life fifteen days before doomsday, Summer Hall no longer clings to family ties. She sells property, rents a bunker, awakens the Super Space System, hoarding supplies. When the apocalypse breaks out, the Hall family is trapped, while Summer Hall survives in her fortress. She gathers survivors, builds a base, becoming a lord of the apocalypse.
