The Demon Hunters had developed a keen interest in Blackbird City.
The more mysterious, the more secrets it held.
They could no longer dig up much intelligence in the western part of the continent, which was equivalent to three new conventional lands, and if they wished to learn more, infiltrating Blackbird City was their only option.
After numerous attempts, they found several different ways to try to gain entry into Blackbird City.
For instance, entering along with the supply channels;
or impersonating someone from Blackbird City;
or directly finding their way to the vicinity of Blackbird City, as a city so large was bound to have unguarded places where one could stealthily slip in...
However, these attempts all ended in failure.
In the process, they even lost several lives.
Ultimately, they finally discovered a reliable method: being recruited.
