The new avatar did not retain the memories of intelligence from the previous Cthulhu avatar, because by the end, that Cthulhu avatar had barely any intelligence left. If those memories were copied over, the new avatar would only become a senile fool.
Nor had the system's examination of that entire universe made much progress. It was all mindlessly eating, eating, eating. He-El had no idea what kind of universe it was.
He did not even have a rough idea.
He-El configured the new avatar's system and had Lucy send it back into that universe to continue developing as a new transmigrator.
Since they already knew that human civilization existed there, with a little manipulation, He-El had Lucy place the new avatar directly into human civilization, preventing it from becoming another Cthulhu monster that only knew how to eat.
After dealing with the avatar's insight from that unknown universe, He-El selected another avatar's insight for observation.
"Such immense resentment!" He-El sensed the avatar's unwillingness with mild surprise. Upon probing further, he saw that this avatar had entered a martial arts universe.
This avatar was also a man of ambition. Though it was an unfamiliar martial arts world, under the system's enhancement, he learned martial arts at an astonishing pace. When he emerged after mastering his skills, he saw a world where "heads hung before horses, women rode behind carts"; where "white bones lay exposed in the wilds, and for a thousand miles no rooster crowed. Of every hundred people, barely one remained; the thought tore at one's heart." Powerful ministers humiliated princesses and imperial concubines, plagues, floods, and natural disasters ran rampant, eighteen nations lay in utter chaos, the common people were treated like pigs and dogs, while the rich let wine and meat rot as corpses froze by the roadside.
