As a Supporting Character, My Liver Has Become the Strongest Creature

[Name: Pei Ju] [Vitality value: 0.8] [Fate: "Black Fist"-Supporting Role] [Talent: Boxing (1 star)] "Beibei, my uncle is Pei Ju, how come he has become a supporting character?" Pei Ju had just sent away the landlady who came to collect payment, when a light blue information panel showing 'supporting role' popped up in front of his eyes. When he discovered that many people had various fates, there were also people whose fates involved mystery, biological evolution, and plural auras... At that moment, he knew, This world is in danger! Fortunately, he can purchase the talents and skills of other plot characters, or enhance his own strength through liver experience! "Three stars in boxing? Buy it!" "Superman's five-star physique? Buy it!" "Full fighting five stars? Buy it!" On the parapet of a skyscraper that soars into the sky, Pei Ju is constantly training. High-five push-ups, one-arm pull-ups, one-leg squats, one-arm handstand push-ups, iron bridges, hanging vertical leg raises, The weather changes with every breath he takes. Looking at the endless blood value on the panel in front of me, looking at the titles that have grown up according to the fate of the supporting characters - Blue Star Village Chief, Sun Sphere Chief, Galaxy River Chief, Universe Continent... (N astronomical units are omitted)... The multi-time and space super omnipotent universe chief. "You're now the protagonist? It's quite simple."
