After the huge earth-element crystals mine was discovered by demons in the 1st loop of Tiewei Mountain, the large-scale battle between humans and demons had lasted over 1 year.
In the first abyss where human knights were crisscrossed with demon knights, as long as one party had some big movement, it's very difficult for them to cover it. The tools and human resources required for exploiting large-scale earth-element crystals would never come out of the void. Of course, the transfer and movement of these tools and human resources would arouse the attention of human management. As a result, human management would make tentative arrangements.
From a certain perspective, the so-called holy war referred to the tentative battles between demons and humans which lasted over 100 years.
All the old knights knew that the so-called holy war was actually a long-term large-scale battle between humans and demons which tested the patience of both parties.
