Before virtual worlds came into being, creating pure structure life forms was very costly and nearly impossible to succeed. The Structure God had only managed to create two types of pure structure life forms since he came into existence.
3D life and 2D life.
For instance, the "Divine Polyhedron" once broadcast on TV channels, although it was just an exquisitely designed pattern, there were indeed beings among the 3D life forms created by the Structure God that could transform into Divine Polyhedron-type entities.
To this day, the existence of 3D life and 2D life still cannot be understood by the majority of people. However, there are those who dedicate themselves to exploring the mysteries of 3D and 2D life, and they are the mages.
3D life can freely change their geometric shapes. They don't even have the 'eating' function of life in the usual sense, but instead directly absorb magic power from their surrounding environment.
