After years of playing nameless background roles and chasing auditions that went nowhere, he was just another face lost in the crowd. Fame felt like a distant fantasy — until one unforgettable night changed everything. In the middle of chaos, a strange voice echoed in his mind: [The Film and Television Martial Emperor System has been activated.] From that moment, Caleb’s life turned upside down.
