Shadow Monarch's Requiem

Jin-Ho Kang was just another B-rank Hunter—one of countless warriors struggling to rise in a world dominated by monsters and guild politics. When an A-rank dungeon scouting mission goes horribly wrong, he and his team are slaughtered. He should have died. But instead of death, he awakens in an abyss beyond mortal comprehension. A voice older than time itself speaks to him, a decree is made, and the truth is revealed—he is no longer human. He has inherited a power that was never meant to be his. The world forgot him. But he has returned. As a Sovereign. As the Monarch of Shadows. And as the boundaries between life and death begin to blur, the world will soon realize… The true King has awakened. — Description from novelcodex.orgFull novel: Shadow Monarch's Requiem — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
