[Comprehensive] What Should You Do If You Encounter a Disaster When You Travel to Another World?

※The first world of this work contains the plot of the little hero (Chapter 1~Chapter 18), please watch it as appropriate. Because it is too long and cannot be changed, I feel very sad inside. If I have bought this work before, I can get half of it back (because the website only gave me half of the money). The second world is that of literary giants. The third world is the black basket.
