Zuan Feng Shen Huo Liu Xing Pao (鑽風神火流星砲, lit. 'Wind-boring divine fire meteor bomb'), sometimes shortened to simply Liu Xing Pao (流行砲, lit. 'Meteor bomb', not to be confused with another triple-barreled breech-loading cannon with the same name), is a cast iron bomb that can be filled with three to six types of gunpowders for different purposes. It is usually filled with incendiary, poison smoke, and blinding dust gunpowder, although other options such as blinding smoke and fragmentation are also available. The bomb is apparently compartmentalised, with up to four separate fuses to ignite each compartment, so that certain portion of the bomb can continue to generate smoke after the rest of it exploded.
Zuan Feng Shen Huo Liu Xing Pao comes in small, medium and large size. The small variant is a hand greanade, medium variant is an explosive shell launched from a bombard or mortar, while the large variant, too heavy to be thrown or launched, is strapped to the back of a pack animal to be used as living bomb.
