Gu Changhe, a young man from Qingxi Village, encounters Chi Yao, a dragon girl who is being pursued and is about to give birth. Untempted by a chest full of treasures, he risks his life to hide her in his home and helps her, together with his mother, safely deliver two dragon eggs. To find the father of her children, Chi Yao entrusts the two little treasures to Gu Changhe. Faced with pursuers searching the village, greedy neighbors, and countless dangers, he protects his mother and escorts the dragon eggs into the deep mountains. After the fire-element Yaobao and water-element Xibao hatch, their first cry of “Uncle” transforms this chance encounter into a solemn promise to protect their new family.
