Primordial Magic Academy

Sirius was transmigrated into a Magical Fantasy World with his previous life's memories intact. The Fantasy World, Zenix, had Humans, Elves, Demons, Dragons, Faes and even Angels living there. After transmigrating, Sirius awakened the Primordial Academy System, and created the Primordial Magic Academy. From accepting the first student, Sirius turned the Primordial Magic Academy from an unknown school to the strongest organization in the Universe. Gods, Demon Gods, Immortals and even the Undead wanted to enter Primordial Magic Academy. However, only the most talented juniors in the universe could enter the Academy. During all of this, Sirius grew stronger and stronger with the help of the System, becoming the strongest in the Universe. Watch Sirius's adventures as in the Mythological World of Zenix as he turns the Primordial Magic Academy into the strongest organization, slaying all his enemies on the way to becoming the strongest of them all while gaining valuable allies.
