In the primitive era, Pangu had just opened the primitive universe. A primitive world in which the process of creation is still unfinished. However, there are already powerful beings walking the earth.

In this era, mythical celebrities like the Three Pure Ones, the Jade Emperor, and Sun Wukong did not yet exist.
