Dian Guang Jian (電光劒)

Drawing of a Dian Guang Jian, from 'Shen Qi Pu (《神器譜》)'.

Dian Guang Jian (電光劒, lit. 'Lightning sword') was an unusual fire lance designed by Zhao Shi Zhen (趙士楨). It was a formidable pole-sword with a broad, double-edged chopping blade mounted on a shaft with a disc guard, and came with two barrels—one handgonne and one Pen Tong (噴筒)—mounted on either flat of the blade.
