Du Wu Shen Yan Pao (毒霧神煙砲)

Drawing of a Du Wu Shen Yan Pao, from 'Wu Bei Zhi (《武備志》)'.

Du Wu Shen Yan Pao (毒霧神煙砲, lit. 'Poison mist and divine smoke cannon/bomb') was yet another Ming cannon that shot explosive shell. It was designed to shoot an incendiary-poison smoke-blinding dust shell to the top of a defensive wall in order to either disrupt or kill its defender, although other types of explosive shells could be used as well.
