Thanks for the chapter!
Think there's a mistranslation because I'm pretty sure LN described the first goddess as an orc, not an oak. Also, more details in LN which tells how his little sister is a brocon, did various things to support and help him, along with a few scary inferences. Not sure how but she somehow was able to successfully sort through stock trades among other things to earn enough money to live on without either of them needing to work again. Btw, he'll figure it out later but there is a difference between earning 20x the experience and only needing 1/20 the experience, especially when in a party. Will let him explain it. Also, pretty sure LN had that dark skin spear wielder give her name when they met. In any case, that crossdressing clothes seller was a hoot, although if trying to look womanly why wasn't the goatee shaved too? Also, in LN there were more bags of holding and money, along with three different colored guide books in different languages. It's explained by author who was a hero long ago that the place is one of the spots where people from another world appear the most frequently, that the bags and money are for such individuals and therefore to take only one bag and x amount of money while leaving the rest for anyone who appears later. The books in different languages give pretty much the same starting advice with only a few variances in suggestions although been a while so forgot what languages were or differences. MC could read two as one was in English and the other in Japanese. Don't think he was able to read third book.
@Xoldin It's not that he doesn't care but is very practical. He has no way to get to his own world, no way to send her a message, and currently needs to learn how to support himself. Also, he knows that she is very capable, very skilled at making money, and very organized. LN gives more details but through the stock trades and various other things had earned enough money for both of them to live comfortably for the rest of their lives without doing anything else. Only reason he was seeking a job was because he didn't want to be a worthless parasite leeching off her and to show to himself that he has the ability to care for and support his sister through his own efforts. So he will worry about her every now and then but hasn't found a way to be able to do anything much less contact her.
