 Another fire lance described in the "Huolongjing" was called the 'lotus bunch' shot arrows accompanied by a fiery blast.In addition to fire lances, the "Huolongjing" also illustrates a tall, vertical, mobile shield used to hide and protect infantry, known as the "mysteriously moving phalanx-breaking fierce-flame sword-shield".This large, rectangular shield would have been mounted on wheels with five rows of six circular holes each where the fire lances could be placed.
