Among all the Duke Palaces, there were also many who used spears, and Duke Zihuan had gone against many who used a spear as a weapon, but he hadn’t fought against anyone from the Yan Family. He’d never thought the power of the Yan Family’s Imperious Spear was this astonishing. The Heavy Profound Spear in Yan Chengkong’s hands attacked and defended freely according to his will. When he attacked, his spear sprung like the wind and clouds, with its momentum able to swallow mountains and rivers. It made the duke’s movements all seem sluggish, as it suppressed both his blade and flame. When Yan Chengkong defended, it was like placing an iron chain across the river, it was impervious.
