In ancient times, demons and monsters roamed freely. At the foot of Mount Tai, a young man named Xiaodang embarked on a journey to find the sacred stone of Mount Tai in order to save his village. At the summit of the mountain, he touched the holy stone, gained divine power, and transformed into Shigandang. Guided by the goddess Bixia Yuanjun, he engaged in a life-and-death battle with the Demon King. In the end, Shigandang defeated the Demon King, safeguarded peace in the world, and became a hero.
