After triggering the mission, Duanmu Huai and the Night Guards rushed back to Hell to combat the demons.
Although this might sound somewhat overconfident, to be honest, if Duanmu Huai had to evaluate, he would say... the demons here were the weakest ones he had ever encountered.
As a Judge, Duanmu Huai had plenty of experience fighting with demons in the game world. He saw the demons under the Four Great Evil Gods to be quite distinct.
The demons of the Brutal God were wildly murderous, fought to the death, and were terrifying when launching an all-out attack.
The demons of the God of Trickery had ever-changing methods, endless magic and evil techniques, which was quite a headache to deal with.
The demons of the God of Plague were covered with viruses and rot, standing there was equivalent to contaminating the environment. If one did not have some protective measures, there wasn't much difference between winning and losing the battle.
