From the Start, I Grabbed the Campus Belle by the Throat as She Jumped, Then Became a Top-Tier Star

(Body-swap, assassin, face-slapping, power fantasy, campus belle, play the pig to eat the tiger, female lead, top-tier star) Think this is a story about a loser making a comeback? This isn't a protagonist's comeback. It's a madman stuffed into a chubby shut-in's body, brutally training the entire world to his will. An Xing, the Wolf King assassin renowned throughout the world, kills as easily as he drinks water and has never missed. But when he opens his eyes again, he discovers he's become a high school student weighing over a hundred jin, a fat shut-in… The campus belle humiliates him in public. Thugs steal his money and slap him. He's bullied and mocked as a simp. “Hah. The cries of the weak.” He sneers, grabs the campus belle by the throat, and leaps from a great height. Let's see how she likes freefall. “Holy crap! That fat guy's taken the campus belle hostage?” “Is he insane? He's jumping?!” Huh? Did the campus belle faint?
