Decide which soldiers you want to merge. 
Line up your arrow in front of the troop and fire your arrow. 
The arrow will select soldiers and then merge them automatically. 
When soldiers are joined by an arrow, they merge and become a high-level soldier. 
Now you are ready to fight an army of top soldiers! 
Go to the battlefield with your top level soldiers. 
The enemy will come your way, defeat them!
But don't forget! You will have very strong enemies. The only way to defeat them will be to determine your strategy and get the strongest soldiers. So set your merge strategy!
