What are keyshops?About 天际防线:空岛传说
In distant mythical times, countless skyislands floated in the sky, miracles held together by ancient magical and elemental powers.
And you will be the reborn prince of the Pumpkin people, building defenses and traps against enemies. Build our home, revive our economy, and restore our kingdom to its glory!

-a thousand Things Wait to Be Done-
The whole royal city has been almost reduced to ruins by the torrent of history. Bulldoze those ruins and wastelands and turn them into people's houses and farmland!
Urban construction is something that must be done. Building and developing the residential buildings of the city will make your city more prosperous and beautiful.




-build Defense-
An arrow tower? The lightning tower? The Sorcerer's tower? Trap? If it works, build it!
However, if we are to defeat these monsters, we may need "a little financial support"!
We have a total of 8 types of defense towers, and we also have many "variant buildings". You can use the power of magical items to transform these otherwise ordinary defenses.




-resist the Monster Enemy-
The kingdom was once full of glory, but it faded in the wind and frost. But these ambitious enemies will not rest there, whether they are monster or air bandits, we must not let them near the heart of the island!
There are as many as a hundred kinds of monsters, each with extremely unique characteristics. When we venture in different regions, we need to find ways to fight against various enemies.



-Magic world-
Do you remember the magic you used in your lifetime? Perhaps not much impression, but it doesn't matter, driving the kingdom of the skyisland adventure, find those lost things!
Oh, right! You have to accumulate magic to be able to use powerful spells, it is common knowledge in the world!
