Some called him Lu the godly doctor, some called him Lu the flayer; some admired him for the mechanical prosthetics that allowed him to rampage across battlefields; some laid under his surgical knife, doomed to die; he could save people from the brink of death, and also destroy corpses without a trace; during the day, he was the warmest goodwill in the human world; at night, he was a terror that made the whole world shudder. The scalpel hung from his fingers, a demon on one side, an angel on the other. His name was Lu Yuan, a double-faced surgeon in a world where spiritual energy had revived, and also a professional ripper.
