Lightning Spear Gu

On Zheng tribe’s walls in Northern Plains, rank two Gu Masters of the lightning spear corps fire five hundred and eighty silverish blue spears about four feet long, condensed from lightning with a soft sizzling sound. The volley clears a large stretch of Fang Yuan’s charging wolf group, piercing even turtleback wolves. Support Gu Masters in the same corps strengthen those spears or converge many flying spears into a stronger combined attack. ^{ch. 480}
