I Became the Strongest Forbidden Mage

Lucian arrives in a world overrun with monsters as a Sorcerer. It's common knowledge that Sorcerers have short lifespans, because forbidden magic feeds on life force. But the truth is, Lucian can't die and his organs can regenerate, but nobody knows that. When he casts hundreds of forbidden spells at once, everyone is completely blown away!
