I Should Learn All the Laws of the World

The talismans in the world, using ink as a guide and paper as a medium, can draw on the power of heaven and earth, imitate the shape of all things, bind ghosts and subjugate demons, call for wind and rain, draw the ground as a prison, and make things come true when they are written. However, practitioners in ancient and modern times can only rely on the four words "natural power". Others cannot get used to it, cannot take it away, and cannot see it. Only Gu Yun could break this iron rule.
