Looking at his less than 100 billion game coins, Wang Xiaoyi felt somewhat uncertain.
"Never mind, let's look at the other upgradable buildings first!"
Upgrading the Spirit Impact Turret from Lv2 to Lv3 requires 1 billion game coins. After upgrading, the damage increases to 200,000 to 500,000 points of Spirit attribute, and the cooldown time is reduced from 30 seconds to 15 seconds.
Wang Xiaoyi gritted his teeth and spent 10 billion game coins to upgrade 10 Lv2 Spirit Impact Turrets to Lv3!
Each of the four basic systems requires an upgrade of 5 billion game coins.
"We can't skimp on this money; the basic system level must be upgraded!"
Another 20 billion game coins gone just like that!
[Ding! Power system upgraded to Lv3, active skill: Instant Acceleration automatically upgraded to Lv3!]
[Ding! Energy system upgraded to Lv3, energy consumption of all buildings reduced by 15%!]
[Ding! Attack system upgraded to Lv3, attack power of all attack buildings increased by 15%!]
[Ding! Defense system upgraded to Lv3, all defensive buildings' defense increased by 15%!]
Wang Xiaoyi's game currency holdings have shrunk again, leaving him with less than 70 billion game currency.
However, there is also good news.
That means Wang Xiaoyi no longer needs to worry about whether to upgrade the [Energy Shield] and [Treasure Detector].
The reason is simple: upgrading the energy shield from Lv2 to Lv3 requires 100 billion game coins; upgrading the treasure detector from Lv2 to Lv3 requires 10,000 game coins.
"Perhaps this is the advantage of not having game currency; you don't have to think about anything else!"
Since acquiring the floating island, this is the first time Wang Xiaoyi has encountered a shortage of game currency. This is quite a new experience for Wang Xiaoyi, who is used to having unlimited game currency.
Fortunately, no new buildings were unlocked after the upgrade to the floating island, otherwise Wang Xiaoyi would have really run out of game coins.
