In the deserts of the Western Regions, young Lu Xun makes a living scavenging until he unexpectedly finds a heavenly text, the Scripture of the Arhat’s Original Vocation in Painting. From then on, he embarks on a path of cultivation: envisioning murals to condense magical patterns, and gathering the power of wishes to build his Dao foundation. He ventures into the caves of the Thousand Buddhas, meets A Yue, a descendant of an ancient desert clan, and encounters a mad painter. In the secret realm of murals, he learns divine abilities such as the Flying Apsaras and the Vajra. Facing prejudice from the Daoist and Buddhist sects of the Central Plains, the covetousness of the Fire-Worshipping Demon Sect, and the shadow of the ancient cataclysm of “Nothingness,” he rises from a destitute orphan to become the leader of the alliance resisting demons. He explores the immortal estate of Kunlun, gathers the Five Elemental Spirit Pearls, and summons the Brahma sound from the Other Shore. With the power of wishes as his blade and the heavenly text as his guide, he ultimately fortifies Dunhuang’s defenses and begins a new journey among the stars, composing a legendary desert saga of Buddhist music about perseverance, legacy, and protection.
