I Ate the Rumble-Rumble Fruit, and You Want Me to Power Streetlights?

Across Blue Star, vicious demon beasts roam the land, while thugs wielding Armament Haki run rampant. After eating the Rumble-Rumble Fruit, Qin Ming wanted to make a greater contribution to humanity. But since Devil Fruits were still unknown to the public, he was treated as a laborer and exploited. In the end, he was poisoned. Once he was no longer useful, they kicked him aside like a stray dog. After his consciousness collapsed, he unexpectedly returned to the moment he'd first obtained the Rumble-Rumble Fruit. All right, all right! Now I get it. What's the point of being a nice guy? The right way is to develop the Rumble-Rumble Fruit to its fullest and become the Thunder God. This time around, you want me to power the streetlights? I'll send a thunder dragon to light up the sky for you. What happens to the electromagnetic field is none of my business. The sharp-tongued class beauty still thinks I'm a lovesick puppy? I'll hit her with a Thunderbolt Tempo and give her electric shock therapy to cure her delusions. When a ferocious beast from the restricted zone roars toward the city and a two-headed black dragon blots out the sky... Divine Punishment! In an instant, dark clouds filled the sky, and a massive pillar of lightning over a thousand meters in diameter crashed down. The beasts and monsters were blasted into dust in the blink of an eye. Qin Ming: “Sorry, but I'm a god.” Enel: “That's my damn line!”
