The Empress Dowager Shen Wan of the Great Zhou Dynasty, in order to save her daughter Princess Changle who was poisoned by a strange poison, and to eradicate the Mu family who was entrenched in the southwest and coveted the national destiny, she fought against everyone's opinions and used her sick body to personally conquer the Helan Mountains in the northwest. Helan Mountain's Heishuiyuan, the place where her bad relationship with the traitor general Xiao Yan ended seven years ago, has now become a devil's cave where the Mu family refines the evil "Medicine Man" and plots to trigger "Sky Fire" to burn down the fate of the country.
Shen Wan carried the verses and half a love jade pendant left by the mysterious veteran of the previous dynasty, and with the help of Taoist Xuan Weizi and others from Longhu Mountain, she fought fiercely with Mu's evil magic and the strange "medicine man". She used her body as bait to inspire the country's magic weapon "Zhenyue Sword", and finally died together with the Mu clan leader at Tianhuokou, but she also exhausted her heart and soul.
When she was dying, Shen Wan used her remaining soul as a guide to activate the forbidden ancient formation "Burning Soul and Casting Spirit", transferring the last vitality and purification power to her daughter A Yuan, while her own soul was scattered. She completely cut off the Mu family's covetousness for the royal bloodline, and recast the Zhenyue Sword into a spiritual weapon. The young emperor Li Hong grew up rapidly on the road paved by his mother's life, and discovered a thousand-year-old secret deep in the Helan Mountains - this place is the "Eye of the Earth's Lines" guarded by the ancient Jumang Witch Sacrifice, and the Mu family is only a thief and polluter. He obtained the "Sheji Map" related to the fate of mountains and rivers, inherited the destiny and shouldered heavy responsibilities.
After returning to the court, Li Hong sent the map of the country to his sister Ayuan, who was in self-isolation. In the silent Changle Palace, the two siblings faced together for the first time the ancient picture scroll that carried the sacrifice of their mother, the fate of their family, and the burden of thousands of miles of mountains and rivers. The frozen lake of their hearts let in the glimmer of light, and a new journey and unresolved undercurrents quietly began.
