Free Mercenary Across the Myriad Worlds

Veteran scout Ouyang Fei gives up his chance to become a third-class senior noncommissioned officer and chooses to retire, desperate to raise money for his gravely ill father. He accepts an old comrade's invitation to join a mercenary group formed by Chinese expatriates. During a mission, an accident leaves him miraculously alive, and a “Myriad Worlds Mercenary” System mysteriously appears in his mind, allowing him to accept mercenary jobs from the Myriad Worlds. From then on, Ouyang Fei takes off. Please confirm: will you accept a job from Yue Buqun, leader of the Huashan Sect in the world of The Smiling, Proud Wanderer, and help him return the Huashan Sect to the peak of the martial world? Hmm, this one sounds complicated, but it's no big deal. Accept. Please confirm: will you accept a job from Princess Iron Fan of Banana Cave on Green Cloud Mountain, in the world of Journey to the West, and help her rescue Red Boy? Uh, I don't think I can take on Guanyin yet. I'll hold off for now. Protagonists and supporting characters across the Myriad Worlds who need help, get your payment ready. Oh, and I don't accept silver. You can pay with cultivation manuals, rare treasures, divine weapons...
