I’m Too OP, So I Decided to Troll My Cute Master Instead of Saving the World[ENGLISH]

Lynn, the God of Magic, has successfully transmigrated to a new world. His objective? Survival. To avoid getting farmed for XP by the greedy local Deities—who love nothing more than fleecing powerful newcomers—he decides to embrace the ultimate strategy: Smurfing. Disguising himself as a harmless Level 1 Apprentice in Winterspring Valley, Lynn is determined to camp in the starter zone until he hits the absolute level cap. He wants a quiet life of pretending to be a noob. There is just one massive glitch in his plan. His Master—a petite, pint-sized girl—can hear his internal monologue."My dear Disciple! Check out this [Forbidden Spell] I just cast! Pretty terrifying, right?" [ That’s barely kindergarten-tier magic. It has the stopping power of a wet noodle. I doubt that splash could even bruise a Slime. ] "Ahem! Anyway... look there! If you grind your mana for another five hundred years, you might just be strong enough to solo that [King-Rank Boss Monster]!" [ Hate to break it to you, Short-stack, but I could’ve one-shotted that trash mob five centuries ago. ] "By the way... where exactly is the five tons of magic theory homework I assigned you?" [ Torched it. Reduced to atoms. ] The air temperature drops suddenly. "Lynn... get your ass over here. I promise I won't kill you." ...Yes, trolling his cute master is fun. But in a world where gods are cruel and destiny is broken, even the strongest prankster must eventually get serious. Because sometimes, to protect a smile, you have to burn the rest of the world down. (Contains comedy, system elements, but gets progressively darker/serious later on.)
