Eighteen years ago, a child lost contact at birth and was rumored to have been abducted. The parents searched hard but failed, and both of them died of hatred. Before his death, he left a red bellyband as a token, which contained the child's birth date, several marks on the body, and a marriage certificate on the fingertips. After completing his studies, the little master came back to find his biological parents, and then helped to rule the Dragon Kingdom. The process was full of hardships and ups and downs.
