In 645 AD, Xuanzang returned to the Tang with 657 Buddhist scriptures. The people of Chang'an poured into the streets to welcome the legendary monk, but he soon found himself caught in an even more complex web: the emperor's political maneuvering, tensions between Buddhism and Daoism, the watchful eyes of Western Regions powers, and the monumental task of translating scriptures to preserve civilization. Grounded in real history and driven by the clash of human ambitions, this story follows the final 19 years of Xuanzang's life, as he wielded scripture like a blade and compassion like a shield, forging a third path between power and faith and ultimately making Chang'an a beacon of civilization for all of East Asia.
