Surviving the Famine

The protagonist sets out into the mountains with a guide and a student to search for materials. Along the way, they accidentally wander into a strange wormhole and enter an unknown world. Here, there are night demons that claim lives in the dark, giant treefolk that guard the woods, shadow creatures from the abyss beneath the earth, and a red-haired girl who eats only meat but is a skilled fighter... When I wake from unconsciousness and look out at this unfamiliar world, can I, someone who has never played a survival game, use what I have on me to make it through the first night? What adventures await in this wondrous world? As I gradually uncover the truth about it, will I ever be able to return to my old world? I can only do my best to stay alive!
