Fuzanglong

In Chinese mythology, the Fuzanglong^[1] (simplified Chinese: 伏藏龙; traditional Chinese: 伏藏龍; pinyin: Fúzánglóng; Wade–Giles: Fu-ts'ang-Lung) is the Chinese dragon of hidden treasures^[2] and an underworld dragon which guards buried treasure, both natural and man-made. Volcanoes are said to form when these dragons burst out of the ground to report to heaven.^[3] Several tiles and light reliefs depict Fuzanglong dragons serving as mounts to Immortals.^[4]

The Fuzanglong possesses a magic pearl which is its most treasured possession.
