Wuxia: After Rescuing Someone from the Ruins, I Bit Through the Rope

When a factory collapsed, I rushed in to save a child, only to be locked in a dark room and interrogated behind an iron door. A knife spun against my neck. I sneered, bit through the rope, and took down three goons. I escaped to Nine-Bend Cliff, where I met a blind butcher. He said I was hard to kill because someone was taking the blows for me. On a rainy night at the mass graves west of the city, a figure had been standing there. It was my mother, long dead.
