The Reverse Mana System

sorry for the week long unexpected break.I had been hospitalized in the intensive care unit.I will resume as soon as possibleWhat curse is this! Even after transmigrating, I have to die at my nineteenth birthday for the second time.Alex Vermillion, the fourth prince of the Flenreth empire is a transmigrator who died on his nineteenth birthday on Earth.He is reincarnated in a world where magic power represents one status and standard of life.But unfortunately, his body has zero tolerance to mana and lacks a magic core.Despite this he is happy just to be alive, but all this changes on his second nineteenth birthday which is also the day when he was to be declared the crown prince. At midnight he is attacked by the elder brother of his body and nearly killed.At the crucial moment the reverse Mana System which has been dormant in his body awakens.This marks the start of his journey to the top in a world where humans, demons, beasts and minor gods fight for dominance, whereas the major gods and high demons who can't step in the world lurk behind the shadows to gain control of the world
