Qin Mu, a 20-year-old boy, traveled through time and became an 80-year-old man suffering from cancer. He was bound to the "Justice Elder System" and needed to punish evil and promote good to continue his life. He specializes in treating various adverse phenomena with his skills such as "disease control by heart". He wakes up framers on the subway, punishes domineering aunts in supermarkets, exposes blackmail schemes, outsmarts human traffickers, teaches school bullies and incompetent teachers, and also punishes those who worship foreigners, health product swindlers and online rumors, and even single-handedly subdues Class A wanted criminals. Running rampant with the "big dick and terminal illness buff", he continued to live in the pursuit of justice, becoming a walking social order organizer, and staged scenes of relieving anger and passionate stories.
