The watchtower at the base was completed, a 15-meter-tall tower standing on the rooftop of the supermarket. The two who returned to the supermarket base couldn't wait to get their sentry duty cards and reach the top of the watchtower.
Beyond reducing the threat level, the watchtower also had a very special function: gunfire noise from the watchtower only posed 75% of the normal threat level. If the gunfire killed zombies, the noise from that shot would be negligible. The effect was almost what Maya had expected, but unfortunately, the night vision was too poor. The supermarket base had no lighting, making it impossible to see distant targets.
