[Main Quest—"March Towards Earth"]
[Type]: Annihilation/Expedition
[Time Limit]: Until the end of days descends, never rest 'til die, never-ending!
[Mission Difficulty]: Extreme Plus Ultra (Supernatural Excellence)
EPU difficulty is the highest level difficulty that can be assigned to any task within "Starry Abyss," far exceeding the usual 3S and its derived difficulty levels.
Theoretically, this kind of task cannot be completed by a player individually; it can only be bestowed as an era's opportunity. Once the mission is initiated, even decades, centuries, or millennia of personal effort would seem inconsequential.
The reward of the task itself has become meaningless, for the sense of achievement gained from fulfilling the objectives and completing the mission transcends all material rewards. Completing EPU in itself is the supreme glory of a "Starry Abyss" player!
