First of I'd like to say this is one of the many ways to explore 25 lands fast.... It worked with my alt so I guess it's gotta work. First Do the tutorial, ask to be volleyed in world chat and explore 9 lands. (there are 2 ways to go. A: go from there. Or B: Reset) what I did is I went from there. Second Build a forge and upgrade to lvl 3 on the 4th land and sell the whatever u built on first land (do not sell guild) and replace with forges. And upgrade guild to lvl 3 Third Once u have 12 maxed out forges get 3 10mil allies. And save up till u have around 30mil and have someone buy your allies. U get the extra cash u need from EBs. Fourth By the time all this is done it will be around the second or third day goes by fast huh? Ok then repeat 4-6 times but add and ally every time. Fifth Once u discover highlands it's your decision if u wanna upgrade guild to max, explore more highlands, or upgrade castle. Any questions just ask and me or another player will answer. REMEMBER this is how I did it and it only took 5 days so it won't be exact time
I was lowland complete on my alt in about a week with the help of 2 other alts doing that as well. Before you buy a land multiply the land cost by 3 and invest that ount in allies to.max out your plunder. it worked for me. About to reset again for the second time after I'm done questing fo crystels.
Easier way is to learn to volley other players. Use the gold you earned from your first volley as your start-up money. Search the battle list for people to volley as, obviously, they're active. Done smartly a player can accumulate several billion in a couple of days. No need to wait to regen. Use troops doing quests and save your crystals.
