It really did.
While temptation was everywhere, Luca had long decided to tighten his belt.
Even when they had managed to pass the ten million mark, the little penny pincher still deferred the level 4 dungeon upgrade.
And his reasoning?
Emergencies.
Also, after careful observation, Luca knew there was always a chance the expense would not stop with just the upfront cost.
Then there was the very real possibility that increasing the dungeon's size would affect the spiritual energy distribution.
What if they failed to provide the required energy crystals?
The dungeon owner didn't want to know. So he made a contingency plan: he would only upgrade once he had enough CP stashed away, but not so late that they missed the benefits. After all, upgrades usually brought massive improvements to everyone, especially to D-29.
He just didn't expect the wait to collide with so many other things.
