Hm, remember that 25% of your storage is secured. Use it to build army that conquering costs more than what you are trying to save up for the build. After some time you should be able to gather the resources for the upgrade :)
Also try to get a group so you can attack together the same target :)
Like I mentioned, that's gonna take a really long time due to how expensive they cost. Chances are I'm going to get attacked and lose progress after I save the troops. It just takes way to much time to upgrade now having to spend so much on troops. It was a first come, first serve type game now.
Right now if ur not a whale its a losing battle when it comes to battles. Your units are gonna keep getting wiped out.
