I Was Supposed to Live as a Layabout, So How Did I Become Invincible?

My clan bullies me, a local thug comes knocking, and in three days they'll demolish my ancestral home and drive me out of Qingyun City! The head of the family, a fifth-stage Condensed Essence cultivator, arrives in person, murder in his eyes, while the whole city waits to laugh at me. At the critical moment, Lin Feng just smiles. With a chicken wing in his left hand and a megaphone in his right, he asks his enemies a question that cuts straight to the soul: “Are you happy?” The next second, a viral song blares across the city. His enemies make fools of themselves in front of everyone, so furious they spit blood! Who says a couch potato can't make a comeback? I cultivate by finding ways to have fun! After transmigrating, I bound myself to the universe's strongest [Joyful Fishing System]! The more happiness I create, the stronger I become! [Ding! Host's prank succeeds, setting off laughter throughout the city. Happiness: +1000!] Spend happiness to fish across the heavens! One cast reels in [Guaranteed-Hit Brick], which ignores cultivation levels and knocks gifted young elites flat with a single blow! The next reels in [Truth Serum], making my sworn enemy expose their own dirty secrets in front of everyone! There's also [Square-Dance Hit Song], [Starry-Sky Gold-Eating Beast], [Four-Piece Dimensionality-Striking Set]... All kinds of bizarre items help me crush anyone who dares defy me! Others cultivate by meditating. I do it by listening to comedy, telling jokes, and throwing parties! Others sever their emotions to prove the Dao. I play a suona tune that shatters the Sacred Maiden of the Heavenly Music Pavilion's Daoist heart, and now she insists we perform together on the qin and xiao! When the whole world believes in the cold “Heavenly Dao of Annihilation,” my utterly out-of-place “Dao of Living Beings” becomes the greatest heresy of all! So what? Once I've fished across all the worlds, even this lifeless continent of Nine Heavens will resound with my joyful melody!
