Reborn as the Wraith King

Marcus Morgan was betrayed and killed by his girlfriend, but he awakens to find he has become a Husk leader, complete with a Husk King System. From then on, humanity discovers that the varieties of Husks are not only increasing but also growing stronger. He tries to control the situation, only to find his enemies constantly evolving. Unknown entities even appear that the system cannot identify, and the situation grows increasingly bizarre.
