He ate a quick breakfast, changed into a pair of heavy cloth riding pants, and followed DingXiang outside to receive instructions on how and when to use GuangZe’s custom hoof boots. GuangZe was very accommodating, and within half an hour the lesson was over. Long slipped the boots into his saddlebag, waved goodbye to DingXiang, and rode into the Gobi’s seemingly endless sea of half-frozen sand. GuangZe’s hooves sank deeply into the shifting sands. The poor animal had to work several times harder than normal for every step he took. Long was happy to see that the sand did not deter the horse, but it did make GuangZe wary, and he changed his gait considerably. Between the shifting sand and his new pants, Long felt like he was learning to ride all over again. After half a day, Long was finally getting used to the new riding motions when the terrain began to change. The ground beneath GuangZe grew firm, and massive rock beds rose ahead of them out of the sand. Long stopped to put on GuangZe’s hoof boots, drink some water from his water skins, and check his map.
