For ease of depiction, "Outer" and "Inner" will be used to represent the London City in reality and its parallel world.
London City. Outer
The dark forest outside the city essentially acts as a defensive perimeter for London City.
Within the dark forest surrounding the London Basin, there roam hundreds of thousands of 'dark evils', including skeletons, Blackrock monsters, treants, and more.
Once they grow into demons, they earn the right to enter the city.
Before this happens.
These evils serve as scouts within the forest, and their 'death messages' are perceived by the priests in the basin villages. The emergence of a large number of deaths signifies the arrival of invaders.
At that time, the priests of the villages will send demon reconnaissance soldiers to further investigate the situation.
However, the current situation in a certain part of the dark forest seems somewhat unusual, as no reconnaissance soldier comes here to investigate, or rather, they dare not come.
