I became a wizard of the Illusion Magic School and decided to create a virtual reality with illusion magic to play a tabletop role-playing game (TRPG).It was great to create a virtual reality, but I was in trouble because there were no suitable players. During that time, I received an offer to be the professor from the Royal Academy.The offer was to use illusion magic to fill the students’ lack of practical experience safely. And so, I became a professor at the academy.“Send me back, send me back to that world right now-!”“Outer god, someday an outer god will be our doom, we’ll all die!!”“I am not the bastard of the Redburn Ducal Family. I am the foremost disciple of the Great Namgung Clan, Namgung Qinghui!”But it seems there is a bit of a misunderstanding.This isn’t a spell for dimensional travel, kids. It’s fiction…

Lu Jun, while traveling in Bashu, casually purchased a White Tiger pendant, only to discover it was connected to the White Tiger Totem.

(The story is designed to be understood without prior knowledge of the original novel, with the setting gradually unfolding.)Through the fusion of dual origins, Lu Jun awakens an innate dual-element talent and gains mastery over the never-before-seen Metal element.In the face of monstrous invasions, humanity's precarious survival, and constant infighting, Lu Jun stands atop the Sacred City and declares resolutely:“I am the King of the World. Who approves? Who opposes?”“Even if I must bear the Abyss of Calamity and hold up the Sacred City single-handedly, I, Lu Jun, remain invincible in this world!”“Sword, come!”With a single strike, the seven Archangels are nailed to the city walls, a sight that shocks all. The bodies of seven Red Cardinals pave a road of blood and boneDisclaimer: I don't own Versatile Mage or the Fan fiction i am just Translating
