《太平广记·卷三百五十七·夜叉二》
我又走了三五里，忽然又见一个骑着披铁甲的马，穿着黄金衣，手持刀剑弓的人，像闪电般飞驰，每一步就能跨三十多丈远，有时在半空有时在地上，跑的步伐一样。
僧更行三五里，忽见一人，乘甲马，衣黄金衣，备弓剑之器。奔跳如电，每步可三十余丈，或在空，或在地，步骤如一。
I walked another three or five miles, and suddenly I saw a man riding a horse covered in iron armor, wearing a golden robe, holding a sword and a bow, galloping like lightning, and each step could span more than thirty zhang. Sometimes in the air and sometimes on the ground, the pace of the run was the same.
