[Sora (空.)]

I afk fished in velia and got
alot of gold and blues and so on but i dont know where to sell it for the most profit i mean should i sell it in heidel ? because when i did go to heidel and wanted to sell it to the imperial trade i couldnt even go to the menu i did connect all the nodes from velia to heidel. So my question where should i sell the fish for the most profit ?
