Outside Guangling Pass, signal towers once stood densely, strategically set up by the Martial Debate Hall to serve as a warning system.
The selection of locations for these towers is extremely stringent and detailed, ensuring that from the high platform of any tower, at least two neighboring towers can be seen, with two Cultivators assigned to each tower, rotating shifts.
Yes, visible.
Because with the diverse methods of the Demon Race, they are fully capable of capturing the towers swiftly, leaving the Cultivators no time to send out messages.
However, visibility changes things; no matter how varied the Demon Race's tactics, they can't deceive, thus providing precious reaction time for Guangling Pass.
It's precisely due to this seemingly grounded system of towers that even when the Black Armor Domain demons suddenly rose up and flattened thirty-one cities outside of Guangling Pass, the Central Martial Domain reacted in time, preventing further losses.
