Huang An naturally understood the principle that an innocent man could be incriminated by possession of a jade disc - he knew this because he had already killed six men over this.
For many martial artists, a handy weapon is like their second life, a companion on which they can depend for survival.
In the army, a convenient iron tool, especially a spear, is something people long for.
With his late Five-Viscera Realm martial arts cultivation, Huang An could protect a normal iron spear. However, he could not possibly protect a specialized spear which exceeded other weapons.
He planned to familiarize himself with spear techniques as he trained in the two body tempering techniques of the Horse and the Fox - there would be great benefits in honing his spear skills in the midst of battle.
In the blink of an eye, a week passed and Huang An had received his first weapon three days prior - a black, child's-wrist-thick iron spear.
