Fusion of All Realms: I Became a Guardian Spirit

The era of fusion of all realms. In this era, all realms began to merge. With the earth as the center, countless worlds began to gather. Magic cards, pirates, ninjas, magicians, martial arts, immortal cultivators... Just like in the legend, the world is no longer a spherical shape, but a round sky and a round place. Countless other worlds are like pieces of a puzzle, constantly bordering the earth, turning the originally small earth into an extremely huge one. Until now, there are still many worlds that are gradually integrating. The female protagonist awakens her ability and summons the male protagonist before the fusion of all realms, becoming her guardian spirit. The story begins here.
