On the Duanhun Cliff, the wind wrapped the gravel and hit his face, like a blunt knife cutting flesh. Lu Chenzhou sat cross-legged on a bluestone on the edge of the cliff, with a knife across his knees. The scabbard is black, the handle is black, and even the blade is made of matte black iron - this "cold iron" has been with him for seven years.
Purpose: Lu Chenzhou killed a mountain tiger by mistake and stayed away from the world.
