Pick up an Oil Bottle at the Beginning of the Wasteland

She is the sharpest knife, cold and ruthless, harvesting life as naturally as breathing. When she opened her eyes again, she became an unknown slave girl who was dying in chains, with heavy shackles and bone-piercing whip marks. In her arms, the trembling little hands of a three-year-old girl were the only weight as her consciousness sank. Top killer? The dust at the bottom of the wasteland? Climbing up from the pool of blood in hell, she dragged her remains and her young sister, and ran headlong into the flames of the oracle that purged heretics, the greedy and corrupt swamps of the plutocrats, and the wilderness of death where giant beasts were entrenched... In this era of ashes written in blood and sand, she once lived to kill, but now she has to fight to protect. Using the heart of steel as a shield and the wisdom of time travel as a spear, she will build a city of refuge that will never fall for the only softness in her arms on this hopeless wasteland.
