Synopsis

Ye Lin is transported to a world overrun by demons. On the day of his class advancement, he becomes an SSS-rank Forbidden Spell Mage—only to be met with laughter and ridicule. Why? Because casting forbidden spells consumes the user's own life force. It's the most powerful class, but also a guaranteed death sentence. What they don't know is Ye Lin's secret: he's immortal. The class's fatal flaw means absolutely nothing to him. When they witness Ye Lin casually spamming hundreds of forbidden spells at once, everyone completely loses their minds. *"Just how many lives do you HAVE?!" "Are you seriously using ultimate-level spells as your basic attack?!"* (Source: Kuaikan, translated)
