Quick Transmigration: The Frail Girl Goes on a Killing Spree

When the doctor told her she had only three months left, Lin Xiaoman calmly signed a consent form refusing further treatment. After twenty-two years with congenital heart disease, she'd long since learned not to plead with fate. Then, on a rainy night, a ball of light crashed into her hospital room: 【Dimension Energy Collection System No. 007 at your service.】 【Transmigrate through twelve worlds and complete your missions in exchange for a healthy heart.】 【Ninety percent mortality rate.】 【Don't want to go? Then your mortality rate is one hundred percent.】 Lin Xiaoman pulled out her IV needle. "Deal." and was promptly thrown into a morgue in the post-apocalyptic wasteland. 【Current heart integrity: 15%.】 【Estimated survival time: 2 hours.】 Lin Xiaoman: "...System, you call this a beginner's village?" System: 【This is a hellish start. Host, find an antidote as soon as possible, or this System will find a new Host.】 And then there was the cold-hearted ranger who'd saved her with three bullets, only to steal her watch. "Escort me to the Noah Laboratory," she said. "I'll treat your injuries, and you keep me alive. A fair trade." The man pressed his gun to her forehead and laughed. "Fair? In the wasteland, fairness is a delusion of the weak." "Then let me become something the strong can't do without." She cured his viral infection, stitched up his knife wound, and pushed her heart past its limits to keep him alive amid the zombie horde. And he lured raiders away from her, fought off mutated beasts, and pulled her back from a cannibal's cooking pot. "You owe me three lives," he said. "Then let me live long enough to repay you." From the post-apocalyptic wasteland to a magic academy, from immortal sects to an underwater prison.
