Ark: A Newbie's Survival Diary

To be honest, this kind of creation setting that is neither an ark nor real is the worst. Just a stone ax cannot be made by just picking up a stone, and the same is true for stone manuscripts. Especially in the Tiesaki period, even if you are given drawings and processes, you will not be able to enter the Iron Age if you don't know how to control temperature and make iron. Let alone the subsequent industrial age, it cannot be made just by giving drawings.
