My System Is a Multiverse

Cavan Ellison was given a strange system. In this system, he can travel between three worlds. In the Western fantasy world, he experienced the powerlessness of being a mage who was slapped to death by a giant. In the world of science fiction, he experienced the despair of being a soldier being plundered by aliens. In the mysterious world, he experienced the constant fear that an investigator must face. So... "System! What use do I need from you!!!" Ps: This article is about farming, leisure, and fun. Readers, please feel free to eat (error~)
