Since the Shields were working with a Mid Adversary, the Initial Shield quickly advanced to become an Early Shield.
The Early Shield still needed a bit more time to advance, but they were on their way to becoming a Mid Shield.
Nick kept diligently working with them.
Another century passed.
During that century, the Early Shield became a Mid Shield.
Now, Nick was working with two Mid Shields and one Early Shield.
The underground city was developing well.
Giovanni asked for more Fallen, but it was impossible for Nick to get more.
Sadly, the Demons couldn't become Fallen.
The reason was the Sun.
The Sun oversaw the advancement of any Demon, Fallen, or Adversary.
Technically, the Sun could infer the underground city's existence based on Zephyx generation.
The underground city did not interfere with the hidden Zephyx tax at all, which meant 50% of the city's Zephyx production went to the aliens.
