The Fallen Brother Is Actually the Strongest: The Strongest Hero in History Is Reincarnated and Unknowingly Unmatched at the School

  I, Eugene, am the strongest hero in history.After defeating the Demon King, I found myself reborn as Julius, the son of a nobleman. It seems that in this world, I was abandoned by my family as a child with zero magical power. I was compared to my excellent twin brother, cuckolded by my selfish fiancée, and looked down upon as incompetent by the people at school and in the mansion. It seems I had a rough life. But I, reincarnated as a different person, don’t care about them at all and decide to live my second life in a carefree manner. At that time, I did not know.That this world is actually the future, 2000 years after my time as the Hero.In this peaceful world, the level of magic and swordsmanship had declined tremendously. I was reincarnated with the best swordsmanship, magic, Recovery Techniques, and Martial Arts of a hero, and wielded the strongest power without awareness in a declining future world. I overturn all the bad reputation and common sense around me, and my lover, family, and my brother, who used to make fun of me, are jealous of me.But I don’t care about that at all, I just continue to enjoy my freedom every day.
