From the 4th century CE onward, Chinese pilgrims also started to travel on the Silk Road to India to get improved access to the original Buddhist scriptures, with Fa-hsien's pilgrimage to India (395–414), and later Xuanzang (629–644) and Hyecho, who traveled from Korea to India. The travels of the priest Xuanzang were fictionalized in the 16th century in a fantasy adventure novel called "Journey to the West", which told of trials with demons and the aid given by various disciples on the journey.
