if you have a look at the control panel on the left hand side it will say "Market" near the end
click on that
if you want you can read all the stuff about it

then click on the "acquire turns" button, and hey presto, you just got 1000 odd turns to raid and farm as you will
have fun
also, if you want to get more Units from raiding, setting relations to war is a good thing, just be careful to not do it to the wrong people

EDIT
having read that u already know
have fun with my description anyway




they need to do better explaining.
