Cursed Caster? I'm Immortal

Future Earth is struck by mysterious radiation, causing human genetic mutations where only those who undergo the 'Class Change Ritual' can awaken superpowers. At a critical moment, Ye Lin awakens as a 'Cursed Caster'—a so-called 'death profession' where casting spells requires sacrificing organs or even life itself. While others fight by strengthening their bodies or manipulating elements, Ye Lin burns himself with every spell. Trading his left hand for a city of flames, sacrificing his right eye to freeze time and space, this walking 'human nuke' must make the most cruel choice between power and life amidst the survival of humanity.
