This Mage's Code is Written Very Smoothly

Transmigrated to another world, I'm a programmer. Pay me? No, patch me! What to do when I discover the magic system is riddled with bugs? I need help urgently! So, I optimized the fireball spell, invented the magic gun, and equipped the elven knights' shields with a "counterattack program." While others were diligently practicing spells, I was fine-tuning parameters; while others were searching for artifacts, I was coding cheats. Demon infiltration? Racial conflict? Kingdom wars? Before absolute technical power, they are all system errors that need fixing. Sorry, this other world has been rebuilt by me.
