The difficulty of system missions is clear: simple, ordinary, difficult, nightmare, and hell, followed by civilization-level missions, such as civilization rescue, civilization catastrophe, civilization rectification, and civilization ascension.
But along this line, there's a small interlude, which is the paradise task, or rather, the hell task's branch — paradise (hell).
In terms of difficulty, the two are quite similar, both being missions from which one cannot survive, unless a dimensional strike is conducted.
But what makes the paradise task special is that it's not about destroying anything or killing anything, but about rescuing life and saving the world, so players often jokingly call it the 'Holy Mother Task.'
Obviously, bringing tens of millions of species into the sea directly triggered the mission conditions.
