The Undying Forbidden Mage: Spams Taboo Magic [LitRPG, OP MC, System]

In a world infested by demons, power is the only currency that matters—but even the [Class Awakening Ritual] comes with a price tag most can't afford.

Ethan Lyle didn't have the gold, so he used a 'glitch' in his own biology. Leveraging his hidden [Undying Constitution], he sold his own organs on the black market until he had enough to buy his way into the ritual.

The result? Ethan awakened the rarest class in existence: [SSS-Rank Forbidden Incantator].

The crowd went from awe to mockery in seconds. In this world, Forbidden Magic is a death sentence. Every cast demands a [Flesh Sacrifice] or drains the caster's [Lifespan]. To the spectators, Ethan was a genius who had just signed his own short-lived death warrant.

They are wrong.

While others hoard their years and fear the cost of a single spell, Ethan treats the most devastating taboos like basic attacks. If a spell costs a heart, he’ll grow a new one. If it costs a century of life, he has an eternity to spend.

“The cost of magic is death?” Ethan watched as a hundred Forbidden Incantations blotted out the sky. “Then I suppose I’m the wealthiest man alive.”

- A Ruthless, Rational MC who treats his own body as a resource.
