weird, so many questions. how big is that other world? is it a whole planet beyond the fence? there's a sun, so are there other stars at night, a whole galaxy, other planets? if the villagers can't see him, won't they see him moving objects, will he pass through them if he tries to touch them? the elf assistant was shown talking to the villagers, so they can see her? where do these villagers come from? if MC is invisible and lifts up a potato, will the villagers see a levitating potato? will they react? if they even can't notice the floating potato, does that mean they are like mindless NPCs? how did he afford to bring tools and masonry as an orphan? story didn't explain how wealthy his adopted father might be. i thought the smoke thing triggers rain from existing rain clouds, so how did he produce rain if there are no clouds? as a father with knowledge about gods and blessings, why didn't the father try to find out the kids' blessing and train them to give them a head start? or is it taboo to talk about it until the ceremony? well maybe i shouldn't think too much.
