I Went from Web Novel Author to Savior

My girlfriend betrayed me, my relatives stole my inheritance, and I became a useless online novelist whom anyone could bully. Then one day, I gained the ability to see the [tags] on everything... The aunt who bullied and humiliated me? Beside her [Sharp-tongued and cruel] tag, I quietly added [Hounded by misfortune]! The rich playboy who stole my girlfriend? [Wealthy family], is it? I changed it to [Bankrupt]! And what about me? I tore off [Sickly and frail] and replaced it with [Undying Divine Physique]! When spiritual qi revived and the world changed, everyone else was still struggling through cultivation. I had already started adding new tags to Earth: [Age of Mythology]! Click to read and see how I go from an armchair critic to the creator who edits the entire world! If you had a pen that could change reality however you wanted, what would you do? My name is Gu Changsheng, and my answer is: I want it all! A cultivation method too difficult? I'll just add the tag [Easy to Master]! A pile of scrap metal? I'll edit it into [Automatic Evolution] + [Divine Weapon]! An enemy is a martial arts grandmaster, protected by indestructible astral energy? Sorry, I can see your tag: [Fatal Weakness: Kidney Deficiency]. In this age of universal high-level martial arts, everyone else levels up by fighting. I only have to move a finger and change a few words.
