My name is Qing Feng. I'm three and a half years old, born with a rare innate thunder body, a once-in-a-thousand-years talent from Mount Longhu. Since I wouldn't grow up, my old master kicked me down the mountain to find my older sister. She's a rookie investigator who just graduated: inexperienced, always looking for fun, and overflowing with a sense of justice. On her first day at work, she was tricked into a demon's lair and trapped in a skyscraper built for tens of billions. I couldn't find her, and I got a little angry, so... I waved at the sky. The next second, divine thunder descended from the heavens, blasting through the building's protective array and its rooftop. Looking at the demons and chaebol family members kneeling all over the place, I tilted my head and asked in a babyish voice, "Which of you are the bad guys?"
