“Here's what happened. I was in a desperate situation when I accidentally encountered a dragon. It told me I was a martial arts prodigy and said it would teach me the Dao of Immortality…” “This excuse for skipping class and cultivating in secret… is that seriously the reason?” “I don’t care whether it’s human or not, what matters is that the dragon said: ‘If you want to become strong, kneel and call me Master.’”

A life I didn't ask for..A world I couldn't call my own...I'm Edward Walters. That's what I'll tell anybody if I'm ever asked. Because, that was the name I answered back one Earth.But now, in this new world I reincarnated in— a medieval one of swords and magic— I'm known by many names.. The Undisputed Prodigy, The Anomaly of my generation, The Legend Blank, and... Charles Liam Flameworth.But I didn't ask for any of these.I didn't ask for the titles, the power, the wealth, the sufferings, the wars, and the fame. I.. I just wanted to go back home. But fate pinned me to this world, giving me no way back.Untill I decided— if fate doesn't give me a chance.. I'll make one for myself. I'll shatter this so called fate, and I'll go back to my family.This is the story of the Anomaly that defied Fate. The one who Reincarnated as a Genius Mage.

Son of the Senior Chancellor, Luo Wei, loved the wrong person in his past life. This mistake caused his entire family to be wiped out, and in the end, he was cast down as a pleasure slave, and died in the wilderness during the depths of winter.

Somehow, the heavens did not give up on him and gave him a second chance at life. He believed this rebirth was only meant for atonement, and not love. Yet, as he plotted his vengeance, Luo Wei quickly realized that passion would again be his fatal downfall.

The once emperor, the lover from his past life, his beloved in this life, and an opposing empire’s monarch who is doomed to love him, who is supposed to be good for whom?

And who is supposed to hurt whom? A hero chasing after a dream, an empire of a thousand years, a kingdom stretching across the known lands, all flashing before the eyes like a mirage. Is it worthwhile to trade a hundred years of my loneliness to give you a single lifetime of joy?
