The Regressor Who Mastered Everything

For 999 agonizing lives, Kang Yoon-soo died by the hand of the Demon Emperor, each time reborn twenty years in the past. He was an eternal plaything, forced to repeat his demise. But with each reset, he gained a new skill, mastered a new art, becoming a grandmaster of every discipline imaginable – from swordsmanship and magic to alchemy and strategy. Now, in his thousandth life, Kang Yoon-soo has returned. He is no longer the hunted; he is a walking arsenal of perfected techniques, weary of the cycle, yet honed to lethal perfection. His patience is gone, replaced by an absolute resolve: this life, the cycle ends. The Demon Emperor desired entertainment, but what happens when its most tormented toy returns not to play, but to meticulously hunt down and destroy its tormentor?
