"Thankfully, the fourth level is a pretty massive place. It won't be possible for him to kill everyone so easily." Krune thought of a solution immediately, returning to his wisp form as he retracted his ethereal form.
He then condensed the Cloud Whale around him, making it as tiny as possible before he flew into the fourth level.
The moment he entered, Krune felt pain from his Wisp Core as his Godly Energy turned sluggish. However, using his Mental Energy to shield himself, he made the Cloud Whale undetectable.
In the meantime, the healing effect reduced his pain to a fair extent, causing him to endure the sensation while the Cloud Whale moved through the fourth level, heading towards one corner, continuing to suffer while he kept track of the situation through his Sonic Radar.
Though, upon seeing that Brenker was able to notice the waves of Sonic Radar, he stopped using it, heading towards another location.
