In the wasteland, others rely on guns, while Lu Rang relies on a knife - a scalpel.
Abandoned like a wild dog by his loved ones and treated as a consumable by warlords, when he was about to die, he awakened the [Cyber Master] system. Others rely on luck to transplant prostheses, but his surgery has a 100% success rate. He can also deeply customize and turn decay into magic. S-class mutants who are dying in the wasteland and defected saints who are hunted by the Mechanicum all line up to beg him for help.
"Begging me to perform surgery? In exchange for your core chip, territory mines, or... Your life." While everyone was scrambling for the last energy source in the wasteland, Lu Rang had already used a heaven-defying prosthetic body to put the entire world on his operating table.
