System + light comedy + face-slapping + no mindless antics + transmigration across the multiverse
A neighboring country’s reckless wastewater dumping enraged an Old God who had slept for tens of thousands of years. In its fury, the Old God destroyed the entire universe. Countless years later, it revived the protagonist and gave him a mission: transmigrate across the multiverse and put the entertainment industry in order. After destroying the world, the bored Old God had become obsessed with human entertainment, but was sorely disappointed by the works that came afterward. So it reshaped the protagonist’s soul.
