The creator of Magic is Back as the Dual Magician

Professor Milles, a certified genius and creator of the current magic system. Misha Raycraft, the 11 years old adopted magic-less son of the president. What do they both have in common? They are the same person. As a genius, professor Milles created the neural system, the origin of all magic which made the world reliant on it. It came as a blessing but professor Milles knew the truth - it was a curse that would doom everyone. To prevent this, he decided to travel in the future and look for a way to destroy the Neural system once the world was stable enough. Now, as Misha Raycraft, the 11 years old adopted magic-less Type Null adopted son of the president, he had a duty to carry out his mission. But before he could, he is stopped by a vision of world destruction and a legacy to prevent it. Now embedded with unimaginable magic powers, it is in the hand of Misha Raycraft to save the world from that destruction while hiding away his magic all the while. However, the task would become even more difficult as time passes on and more and more people begin getting involved in the salvation of the world. He would do it all, even if he had to become a Villian in the process. However, to do this he would need allies in this new period. Especially those who could help him out. But personal relationships of other people, namely - Xion and her harem of power female magicians hailed to have the best potential might hinder Milles and his journey. (Both the harem and Yuri are in the background for now and not with the MC but they will become very important elements in the future.)
