Okey, now it looks dump question but whenever I get my turn, I click on neighbouring contries to expand my territories but I cannot get green arrows to go there. Whole window remain static. There aren't any activity, despite of clicking thousand times on my territory to neighbouring territories. Is there any other way to fight my neighbouring territories to expand my territory? or how should I exactly use my turn?

Thank you in advance, I hope my question get solved.

It depends if you have an army of that territory. An army is that chesslike piece that looks like a calvary unit on it. Only with an army can you conquor territories.

Always try to attack the capital territory using the accumulated bonus.

are you clicking on your territory or your army?

Wait . . . turns? I'm quite confused here. I'm only playing a demo so I'm not sure if this is another game type or not (the demo is for Thrones and Patriots).

Its the conquer the world scenarios i think there should be the alexander the great one in the demo but i'm not sure.

Yeah I think you're right. It's the conquer the world thing.
