The Heaven-Cursed Costs Life, But I Have Infinite Life

The Eldran Continent is a land filled with many races and monsters.Humans are the official rulers, yet they are surrounded by powerful enemies. Fortunately, if a human reaches the age of 18, they might awaken a profession and gain great combat power.Allen Walker was an orphan from the slums, yet he awakened the SSS-rank profession,The Heaven-Cursed.Users of The Heaven-Cursed can only cast Forbidden Spells, but using them costs their own life.No The Heaven-Cursed user in the Eldran Continent has ever lived past 30. But Allen seems to have infinite life.If The Heaven-Cursed costs life? Let's just add one million years to it.And so, a madman no one dared to mess with was born on the continent.A local thug cried, “Boss, I just stole a piece of bread. Wasn't it a small thing? Why use a Forbidden Spell on me?”A Vampire Prince bowed. “Lord Allen, may I have just a drop of your blood? In return, I'll give you my daughter in marriage.”The Dragon Realm pleaded, “My lord, take all the gold in my treasure hoard. Please stop using Forbidden Spells on me!”The Demon King shouted, “Are you crazy? Using Forbidden Spells like that will kill you! You'll die if you keep this up!”...Ten years later, Allen finally turned thirty.All the races of the Eldran Continent threw all-night parties in celebration.A Great Dragon roared, “It's been ten years! Do you know how I survived these ten years? That jerk is finally dead!”The Demon King cheered, “Today, we attack the human world to celebrate!”The Light Pope laughed, “Now, who dares to defy me?”Just as all the races became reckless and thought nothing was off-limits, they froze in terror. Allen was still alive.Thirty more years passed, and Allen was still alive.Three hundred years later, Allen used his Forbidden Spells like basic attacks.Three thousand years later, the continent was unified, and all races paid their respects.The Demon King knelt respectfully on the ground and asked the question on everyone's mind,“My Lord, are you truly immortal?”
