After McKinney's death, Swain immediately commanded the Slave Creature Legion to begin attacking Wilderness City.
When they attacked, they found that the resistance was even weaker than they imagined, and soon discovered that many orc troops within Wilderness City had escaped via multiple special teleportation arrays.
It was just because of their large numbers and the few teleportation arrays that they couldn't all evacuate within a short time.
McKinney's challenge to Arnold was actually to buy time for the orcs inside the city.
The Black Sail wizards discovered this only after detecting frequent spatial fluctuations, otherwise, Wilderness City might have soon become an empty shell.
Black Sail immediately seized the momentum and directly took Wilderness City, also sending a significant number of Slave Creature Legions to various parts of the Wilderness Continent to pursue and capture Green-skinned Orcs.
