I do not remember much from this story at all but this is what I do remember. First our main character I believe is reincarnated but it is not the usual story. At the beginning of the story he is the strongest in the world and he has no one else to fight or get strong because of the crest he was born with being not for battle but for production. After he hit this bottle neck of not being able to go into the higher world to fight people he activates reincarnation magic and reincarnates.
He gets the new sigil which I believe is on his hand but in era the people who have the battle sigil are actually looked down upon because it take much more practice to start out but it overall more powerful. People believe that the sigil that start out very quickly is better but in reality it is weaker in the long run.
