LostWizard
For someone with power like MC, these last 3 episodes are just nonsense. With the abilities he has and the memories he has, it should be impossible for him to act like this. If there is character development in the novel, MC shouldn't be like this. Everything he does in the last 3 episodes should be meaningless for him.
With the years he lived, the memories, the experiences. I don't think he will do these. But I remembered something I forgot, this is just a fanfic. So the writer writes what he wants.
LostWizard:Why? Would u not like to have a powerful and cool armor and weaponry? I definitely would. Also i just want to mention that he doesn't have any protagonist luck, so he might end up in worlds that are way too weak for him yet he will still squeeze the world dry until it doesn't have anything that could benefit him.
