If even a single legend hasn't been passed down, it's highly probable that the requirements for further evolution of the Kingdom Slime are too rigorous, to the point where the conditions can't be met solely on the Star Continent and require venturing beyond the stars.
Going out is easy, but returning is difficult.
Even if the Kingdom Slime truly completes an advancement in the starry realm, it's highly likely that due to the breakthrough in power, it won't be able to fully descend onto the Star Continent.
This is the most reasonable truth behind "there exists no evolved entity beyond the Kingdom Slime".
Louis chuckled and said, "It's okay, after all, Limuru still has plenty of evolutionary opportunities. The Underground City, Bottomless Abyss, or even Bator Hell, might not necessarily be off-limits."
Olivia looked at him in amazement and said, "You're really not afraid of death, still thinking of going to those places."
"Getting stronger brings confidence, doesn't it?"
