In order to extend his life, Luoluo made an agreement with a quick travel system and went to various worlds to save the yandere boy who had turned black.

A cute little wolfdog, a sinister national master, a weird zombie king, and an infatuated emperor. . . . There are all kinds of male protagonists.
