Summary
In a world where martial arts reign supreme, two opposing forces—light and dark—define the balance of power. The once-feared martial emperor, Jang Tae-yoon, betrayed by his closest allies, falls in battle and loses everything. But fate has other plans. Reborn into his younger self, Jang is given a second chance to reclaim his throne and settle old scores.
Armed with the knowledge of his past life and the power to control both light and darkness, Jang sets out to master the arts he once wielded. Along his journey, he faces powerful rivals, uncovers hidden conspiracies, and grapples with the conflicting forces within himself. As he walks the line between hero and anti-hero, Jang must decide whether to seek redemption or succumb to vengeance, all while striving to become the ultimate martial emperor once more.
