Wubei Zhi (Vol. 55)

The staff is forged from wrought iron with a hollow center to store lead pellets and divine fire used in conjunction with poisonous fire medicine. The body is three feet long, with a four-foot wooden handle. Brave soldiers hold it to charge into cavalry formations. Another method is to forge it from iron with both ends resembling lead-pellet firearms, and the middle section partitioned. One end is loaded with fire, and the other with pellets. This is highly effective in battle.
