Uargghh!
Robi somewhat shouted while using his innate skill. His expression was solemn, with his veins starting to pop up on his face and neck.
Robi's eyes were slightly enlarged and reddened as if tiny blood veins had sprouted in them. His skin is flushing, and his muscles appear enlarged. Given the appearance of his body after using his innate skill, his body now resembles that of a bodybuilder.
Angga took a few steps back, hand in hand with his guardian spirit. He looked worried, as if he were aware of the effect Robi's innate skill had.
Seeing Angga move away, Robi then moved closer to Angga quickly. The breath that came out of his nose looked like early morning smoke. His two legs, which were like a cross between a beast's and a human's, stepped hard on the floor of the arena.
It is very visible that Robi's physical strength has increased dramatically when using this innate skill. Furthermore, his movements, particularly his footsteps, are becoming faster.
