[Congratulations! Your Prison (Lv1) has been upgraded to Prison (Lv2)! Would you like to upgrade for 5000 Wood, 5000 Stone, and 5000 Gold?]
[Prison (Lv2): Capacity 3000 prisoners. Capable of completely weakening Level 40 Elementalists and below.]
She accepted and the change immediately took effect. Because she built downwards before, this upgrade built upwards.
Morbidly, the requirement for the System Prison upgrade was to consume a certain amount of life force. Because they had so many prisoners on the stronger side, it also upgraded relatively quickly compared to others.
She didn't have to remove the current inmates either, it'd just build upwards.
As for the manual prison, she didn't want to expand it. Even if they expanded their population, she hoped that the crime would still be at a manageable level.
