You should have 23 farn houses and only 1 mansion. The clan you join is crucial for getting silver. Its not going to come from your city. You will need the farm houses as you grow and your army grows with you.
hey! just something to add for new players. dont press collect all/ help all. for every help and chest you open you gain points in your clans wealth. so of you click help all you only get 1 point for all the chest, instead of multiple for clicking them individually. it helps your clan to grow faster.
