I Cast Forbidden Spells Until the World Breaks

Zayne Locke crossed into a world eerily similar to Earth… except this world is shared by humans, yokai, beasts, demons, and even gods themselves. And the talent he awakened with was absolutely broken he literally cannot die. Ever. But the Job Change Ceremony demands an absurd amount of money. So what did Zayne do? He abused his undying talent and sold his own organs to gather the fee kidney, liver, cornea, all sold because they grow back minutes later. On the day of awakening, he became an SSS Forbidden Spellmaster and the crowd instantly burst into laughter. To them, it was the most pathetic SSS class ever created every forbidden spell requires sacrificing lifespan or flesh. Forbidden Spellmasters never survive long. But only Zayne knew the truth with his undying talent, the fatal weakness of this class… simply does not exist. Short-lived? What does that have to do with someone who literally cannot die? So when Zayne casually unleashed hundreds of forbidden spells like they were basic attacks everyone completely lost their minds. “Bro… just how many lives do you HAVE?! Who the hell uses forbidden spells as their normal attacks?!”
