The xun lei chong (simplified Chinese: 迅雷铳; traditional Chinese: 迅雷銃; lit.
'Thundering fast firearm') is a revolving-barrel, spear-combined musket.
[1] The five thin gun barrels of the xun lei chong are connected behind a reinforced shield: like the five thunder divine machine, the gunner could rotate the fuse 72 degrees and swiftly light each barrel with his match.
The central firing device is a combination of a detachable spear, five tubings, and a firing mechanism, all fitted together with interlocking grooves.
The shield could be pulled off from the front and slung on the hand, and the gun's rest is a double-sided hand axe.
