The wasteland chronicles the years, resources are depleted, and strange beasts are rampant. Su Zhenyue was pushed into the herd of mutated beasts by her most trusted teammates, and fell bloody in the ruins. When she was about to die, the substitute ability that had been dormant for twenty years suddenly awakened in her body - it was a strange black shadow that could copy the abilities of others. Her teammates thought she would definitely die, but three days later they saw her at the largest auction house in the wasteland. "When you pushed me down, did you ever think that I would crawl back?" Su Zhenyue's lips curved into a sneer. What she doesn't know is that the real price of the substitute's ability is that every copy is eating away at her upper limit of life. In the wasteland, the weak eat the strong. If she wants to survive, she must be stronger than anyone else.
