Mocked for Fake Muscles During a Fitness Livestream, Then My Demon Back Is Revealed

Liu Yefei transmigrates to a parallel world and obtains the Demon Back System. As long as he livestreams his workouts and completes missions, he can increase his Demon Back progress. He originally just wanted to casually boost the progress bar a little, but unexpectedly, his livestream became a huge hit. In the end, people all over the world were following along with his workout routines.

A boxing champion: "Heh, those muscles are obviously fake. A pretty boy like that? I could knock out ten of him with one punch!"

A netizen: "Holy crap, what's going on? His back is terrifying! Is he a martial artist from an ancient school?"

A reclusive family: "Wasn't he already dead? Why do I sense such a terrifying aura from him? Send someone to challenge him immediately!"

Liu Yefei: "Uh, what are you all trying to do? I just want to livestream and help everyone get healthy. Can you leave me alone? If you push me too far, then we'll all go down together!"
