Chapter 1641 - Demon King's Descent
Twenty-meter-tall walls surrounded Ancient Rock City, strengthened by magic runes. Even powerful players would not be able to scale these walls. Furthermore, a defensive magic array protected Ancient Rock City, so even if players managed to climb the walls, the magic array would stop them in their tracks.
Normally, players could only enter Ancient Rock City through its main entrance.
If players with nefarious intentions couldn't even break past these two defenses, they'd have no hope of getting past the NPCs patrolling the city, and their attempts would be for naught.
Due to the Orc Empire's unique environment, players consumed Stamina and Concentration more quickly in the area. The only way they could recover their lost Stamina and concentration was to enter a magic array-enclosed town or city.
