Every creature, whether it was a monster or a human, whether it was an arrogant person or not, everyone to one degree or another had either a teacher or someone they learned from and became stronger.
Sure, the differences were significant in a situation where the apprentice had a teacher, and they spent a long time practicing and working on weak points. Adam had lived like that for the last three months under Tron's mentorship, and at times Max had taken over that role.
But... oddly enough, even though it was a long period, it didn't affect Adam's path - at all.
True, he became stronger and learned to use his abilities better, but Adam didn't get anything new, it's not about abilities or equipment but about memories, because they were part of the Phantom's path.
Based on past events the Two Walls were created, this was Phantom's main obstacle on his way to the K3-Level, opening up completely different possibilities than anything that came before.
