"Magic? I prefer science. Let me show you what absolute control looks like." Chen Fan was the strongest Esper on a dying Earth. When he transmigrates into the magical world of Earthland as a child, he brings his terrifying power with him: Vector Manipulation. He can control the direction and magnitude of anything he touches. Heat, gravity, kinetic energy, magic everything obeys his calculations. Follow Chen Fan as he rises from a humiliated, powerless child in a forest to the most feared mage in the world. When he crosses paths with the rowdy, destructive wizards of the Fairy Tail guild, the world will never be the same. Dragons? Demons? Dark Guilds? They will all learn that the laws of physics are far more terrifying than the laws of magic.
