After leveling up, Queen didn't walk any further. She said, "My fitness isn't good enough to proceed. I won't bother trying to go any further, and I'll simply wait for you guys here."
Han Sen could see she was actually able to go forward a little bit more, but chose not to. Han Sen really admired her character, and he imagined Queen's Heavenly Go must have been fiercer than ever by now.
After the tenth curtain of light, some creatures showed signs of leveling up. But it seemed the chances of them leveling up were low. The ratio was around one in twenty. The others, even if they reached a point where they could no longer go on, were unable to level up.
In order to level up at those stages, you had to be below gemstone class. Those possessing gemstone self geno cores could not have their geno cores ascend to super class.
