The demon core already begins to affect those battlefields. Fortunately, with the presence of those legendary grade Warriors and with the additional reinforcement, those people were able to hold on until Sam did not put those artifacts in his inventory.
Definitely, the person who is linked with those artifacts is trying his best to activate every one of those artifacts at once.
Other than that many of those Abyss humans became self-destructive. It Looked like they received some kind of order from their superior and in the next second all of them decided to explode themselves.
Unfortunately, they underestimated the response of the Warrior Association. The Warrior Association currently watches over every part of the battlefield.
Most warriors present inside the Warrior Association did not want to meet a single detail.
