As for how to lure these enemies out, I already got an idea about what to do. However, to do it, I had to get the help from the system, and also if possible the help from other contestants participating with me.

The content of the disaster they were facing was the same. They were trapped inside a closed time loop that they couldn't come out from.
The main difference between this and the other quests in the list was that this race was facing the threatening danger already in the quest. They were in an all out war against a mysterious enemy, and they kept losing at the end.
The world ended by the death of everyone and the destruction of the entire planet before time would reset and things would return to the climax point of such a clash.
