บท 824: Improving Iron Mountains (Part 2)

Although Guia had a lot of gold, it naturally couldn't afford the dense sentries that Alterra had. The walls alone had consumed almost all of the gold she won from Guia.

Hence, like what she did with Limestone Valley, she chose to add dense sentries in the more sensitive areas like the gates and added watch towers everywhere else. Anyway, sentries were more useful in beast mobs, which were more active by the gates. 

In wars, people tended to be more creative—sending forces that would not focus on attacking the well-guarded gates. They'd also be sneaky in trying to get over the gate. In such cases, some human factor would be useful.

She, however, added a lot of interior watchtowers for efficiency as well. It used a bit of her own funds, but it was worth it for her peace of mind.
