Drug-Eating Genius Mage

A brief description of the manhwa Drug-Eating Genius Mage: Our protagonist has been swallowed by a game – ending up in a huge city called Valkan. And in order not to suffer any penalties, he must survive in this world by pushing his magic to the limit, meeting new people and trying to discover the truth about the “other world”. Thus preventing the apocalypse from reaching his true world. [By the studio that brought you <Damn Reincarnation> and <Player Who Returned 10,000 Years Later>!]
