Zhou Jiahao appears to be the owner of a used bookstore in an urban village. He has a gloomy face all day long and has little contact with his neighbors. No one knows that he was once the youngest special service genius of the Ministry of National Security. He was framed during a mission and his superpower core was destroyed, and he has been anonymous ever since. However, the conspiracy that led to his fall three years ago is not over yet - an evil organization "Abyss" composed of mutants with superpowers is quietly infiltrating the city. They use superpowers to control people's hearts and create disasters. The man behind the scenes is Lin Moyuan, the former comrade who betrayed Zhou Jiahao. When innocent citizens fell into strange comas one after another, and when the official power was retreating steadily, the destroyed superpowers in Zhou Jiahao's body unexpectedly awakened - he gained a strange ability to devour other people's superpowers and turn them into his own use. The gloomy second-hand bookstore owner was forced to return to the world, and in the midst of the whirlpool of power and dark forces, he launched the most turbulent counterattack in the most silent way.
