William calculated the points, '2935 are left huh, That's a lot.' He thought.
'With this, the bots are maxed again, I need something that can protect the tower even when I am not there, I need to make it self-sufficient…'
His gaze fell on two specific upgrades, 'Auto-Repair System' and 'Energy Shield'.
'If I get them, 800 points will leave right away but… at the same time, they will also help in the long term. It's not like I can get the library of skills in this wave.'
