Railways: Does She Want to Be My Driver?

As a pure Glamoth mech, an intelligent machine personally awakened by the Medicine Master, Chuanwu has seen too many of his kind abuse the Medicine Master's blessings. Resolutely taking up arms to fight back, he wandered alone for centuries. "Those who receive blessings must follow certain precepts and respect certain boundaries." After fighting alongside the Xianzhou Yaoqing for three hundred years, Chuanwu realized that the Xianzhou's power alone had its limits. The Reignbow's Hunt resolved the immediate crisis, but the suffering civilization still teetered on the brink of life and death, with little hope ahead. "Violence alone cannot correct the abuse of the Medicine Master's blessings."... Many years later, Chuanwu had earned countless titles: the Medicine Master's only divine envoy, leader of the intelligent machines, eternal ally of the Xianzhou, the flesh-and-blood mount of General Feixiao, and many more... With a microphone in hand, Jimi asked, "What drove you to reach the position you hold today?"

"Someone has to forge a third path. Why shouldn't it be me?"

P.S. One female lead. The heroine is Feixiao.
