After Being Single for Thirty Years, I Became a Great Mage?

Chu Nan, 29 years, 364 days, 23 hours and 59 minutes, was only one minute away from the legendary Grand Mage - and then he traveled through time. The good news is that the Grand Magister System is late but arriving. The bad news is that the world is full of superpowers and there is no magic. The worse news is that the system told him: Want a spell? Go kill the superpowers and plunder their power! As a result, the style of painting started to go wrong: Facing the rock superpower, he handed over a modified pistol that "can shoot backwards." Facing the flame superpower, he picked up the rusty rebar and shouted, "A gentleman has no weapons." The system rewards him with Stone Skin Technique and Fireball Technique... But he always wants to put buffs on himself and become a melee mage. "Where is the graceful singing that was promised? Where is the destruction of heaven and earth that was promised?" "Why does this Great Mage become more and more like a terrorist?!" This is the story of an unlucky man who lives up to his name as the "Great Mage" in the world of supernatural powers in the least magical way. "So, when the flame superpower roared and set off a sea of ​​fire, Chu Nan put on [Stone Skin Technique] on himself, picked up a piece of rusty rebar and rushed in. While screaming that it was hot, he shouted: 'Playing with fire and peeing on the kang! Pay for my pants!'" ——There seems to be something wrong with this road to becoming a god.
