Injury in Exchange for Life

Injury is my price. Life is my receipt. On the day Lin Qi was captured in the Northern Park, he didn't know he had a special ability—— If someone hits her, she will take away a year of their life. Someone stabbed her, and she took away ten years from him. Others pushed her into the water, and every time she came up, her life was shortened. The more she was beaten, the longer she lived. The more injured she is, the faster her enemies die. The thugs in the park suffered "cardiac arrest" one by one, and the cause of death is unknown. No one knew that the woman locked in the water prison was using their lives to keep herself alive. But she soon discovered something - She couldn't survive without someone hurting her. If everyone was afraid of her, avoided her, and dared not touch her, she would have no choice but to watch her lifespan run out little by little, until one day she would no longer feel the coldness of the water prison. She lived a long time. So long that everyone she loved was gone. It's been so long that she can't remember what the first person who made her laugh looked like. The last person in the world who dares to hit her is herself. No male protagonist. No redemption. Torture to the end. Are you ready?
