Empty: Door

Above the high-dimensional sky, the empty door suddenly opened. There is an invisible void above the city that ordinary people cannot see. Whenever the tide of the empty layer ebbs, the door of high-dimensional space opens wide, and a large number of air energy particles fall from the collapse of the high dimension, and strange energy falls into the world. Human beings infected by air energy particles will awaken exclusive powers. Each person's awakened abilities are different, with many attributes and thousands of branches, and there are no completely duplicate abilities. Human beings who have awakened supernatural powers are collectively called: empty-powerful ones.
