all you have to do is nothing

like I said in the title. Even the armed peasents cost 5.

no way to get free soldiers.

I dunno but here is a trick to get gold:
Buy a Monestary. Put the game in pause. Select the rubber and try to erase the monestary. It wont delete! but when deleting, look to your gold. It raises! A LOT. Why? Because you get ALWAYS half of the recourses you spend building it. And you can also sell the stone and receive more gold! I finished the game with the help of that trick. When you dont want more gold, click again on pause and the monestary dissapear.

we all now the gold trick ok so just shut up ok
