After killing all the ratbos, Kai was still welcomed within the Elven Kingdom, and the king even went as far as to say that he would always be welcomed with open arms.
Kai was surprised since he would definitely try to go to the Trial of Monsters and potentially hurt the elves guarding it. However, it seemed like the king did not care for such things, or, at the very least, it did not show on his face.
After Kai left, he went into the forest and killed off a few monsters so that he would reach the 35,000 experience mark and achieve his 4th Growth Stage before his evolution. That way, he would obtain a completely new skill that he would still be able to utilize in his next evolution.
And that's exactly what he did as he obtained a brand new skill called: [Dragonic Knowledge].
