Two time and space that have never overlapped, people who have never disturbed each other, people with mysterious powers. One time and space - Qingjie and the other time and space - the floating world.

Little did they know that in the other time and space - Qingjie, there will be any concept of this time and space, and it is even more difficult to imagine that there will be any intersection with it, or even opposition to each other. Compared with people in the floating world, people in the Qing world can be said to be different.
