In the Zhenguan period of Tang dynasty (628 AD), Xuanzang and his west-bound team are walking on the Silk Road. Desert, poisonous spring, torrent, and swamp -- the western regions are welcoming the Buddhists from the east with her wildness and colorfulness. On the long journey to the west, Xuanzang faces the sinister human nature for the first time in his life -- bad trade caravans on the silk road and bandits on horseback in the desert come ferociously at them. At the critical moment, Buddha guides him into a dreamy kingdom of women. At the top of Mount Ling, the west-bound team suffers an unprecedented heavy loss, and the extreme coldness, strange disease, the horrific legend, collapse and death are testing everyone. Xuanzang doesn't know what's waiting for him ahead. 19 years+56 countries +110 cities +1335 rolls of scriptures +25,000km road=Xuanzang's journey to the west. The emerging Tang dynasty, the Turks on horseback, the mysterious Central Asia, and India where many thoughts collide - all are shown in Xuanzang, a lonely traveler's bitter quest for truth, which is literally the greatest adventure in man's hiking history.
