After the Nightmare Star reached Level Six this time, its Expansion Space increased by four slots.
When a player's ship advanced from level five to Level Six, the Expansion Space gained doubled from one slot to two, while a combined ship gained four.
Future upgrades would probably work the same way.
Yang Yi planned to build the Great Statue and the Glass Cannon, the two Expansion Buildings that came with the Special Ships.
What he used the remaining two Expansion Space slots for would depend on his draws. Ideally, he would get unique special Expansion Buildings, whose functions would be stronger.
After some thought, he made a few random draws for "Expansion Buildings Card (Small)."
[Nightmare Star unlocked Expansion Building-Standard Operations Room] [Nightmare Star unlocked Expansion Building-Seaside Brewery] [You drew the Seaside Bakery. Duplicate Expansion Building. Refunded 250 player points.] [Nightmare Star unlocked Expansion Building-Gym] [You drew the Standard Operations Room. Duplicate Expansion Building. Refunded 250 player points.] [Nightmare Star unlocked Expansion Building-Watchtower] [Nightmare Star unlocked Expansion Building-Mast Observation Platform] [Nightmare Star unlocked Expansion Building-Reading Room] [Nightmare Star unlocked Expansion Building-Large Sail] [You drew...]
Without so much as blinking, Yang Yi made 109 draws, spending a total of 54,500 player points.
Of those, 67 were duplicates, refunding him 16,750 player points. The further he went, the higher the duplicate rate became.
When his last 20 draws all turned out to be duplicates, Yang Yi decisively stopped drawing. He had already drawn the vast majority of common buildings, which fell roughly into four categories: naval combat, training, production, and exploration.
Various combinations of some of these would make up the starting building lists of other common ships.
Yang Yi was interested in the Gym, though its effect was somewhat poor.
