Read manhwa Chronicles of the Demon Faction online in English. Also known as The Demon Faction's Return and Mado Jeonsaenggi.

Chun Hajin spent his entire life operating from the shadows as the ultimate assassin for the orthodox martial arts alliance. When he finally attempts to escape his masters and claim his freedom, he is violently betrayed and hunted down. However, death is not the end for this seasoned killer. He unexpectedly opens his eyes in the body of Seo Ryang, a despised young prince belonging to the Heavenly Demon Cult—the absolute worst enemy of his former employers.

Trapped in a frail new vessel suffering from blocked energy pathways, the former assassin must survive the cutthroat political landscape of a sect where weakness guarantees execution. Relying on his vast combat experience and an unbreakable resolve to live on his own terms, he begins rebuilding his physical strength from the ground up. As he outsmarts his treacherous new siblings and rapidly climbs the ranks of the demonic faction, he sharpens his blades for the ultimate payback. The so-called righteous heroes who ended his past life have no idea that their greatest weapon is coming back to destroy them.
