This phase of attacking the pearls was not difficult at all. As long as the players were quick enough in their attacking an dodging, they could beat this whole segment relatively easily.
The only thing was that this segment was extremely long. After Li Yi and company fought for nearly half an hour, the Sky Emperor's gigantic body finally started to break and crumble.
As countless blue pearls burst out of its body, flying all over the place, the Sky Emperor's body slowly started to shrink, reverting to the size of a human.
The next phase was much easier. The now smaller Sky Emperor was nothing more than an "Empyrean Guard" with a HP boost. As long as the player avoids its "Sudden Impacts", they could just slowly toy with it till death.
Half an hour passed by in the blink of an eye, as the Sky Emperor's HP went down to zero, it fell to the ground.
