In the Daxia Dynasty, martial arts flourished and immortals and mortals coexisted. The royal family practices "True Dragon Art", there are many sects in the world, and the Beili Kingdom in the north is eyeing it. The two countries have been at war for decades.
Deep in the palace, the most unfavored ninth prince, Li Xuance, was born to a palace maid named Concubine Jing. She died suddenly after giving birth to a dragon son and was raised by a wet nurse since childhood. Over the past fifteen years, he has learned to "hide the front and guard the base", surviving like an ant amid the bullying from the princelings and the indifference from the queens.
In the winter of the seventeenth year of Taiping, Beili negotiated peace and named a prince as his "brother-in-law". This was a great shame and humiliation. The eyes of all the civil and military officials finally fell on this "most suitable" abandoned son.
