Shen Ji, the descendant of the last mountain guard, married into the Taihang Jiedushi Palace with a marriage certificate. As a living map, he joined forces with her husband Xiao Yan to defeat the enemy on the ancient road of Taihang Eighth Routes, and finally revealed the true secret of the Taihang Eighth Routes Map.
The knowledge of the mountain keeper is engraved in her bones and blood. The "Taihang Bajing Tu" that her father protected with his life is now her responsibility. Marrying into the Jiedushi Mansion was originally a clue to the search for his father's death, but on the thousand-mile ancient road in the Taihang Mountains, he gradually found a road wider than revenge.
When he first met her, he only regarded her as a political pawn. But her prediction at Puyinxing, her defeat at Zhiguanxing, and her redrawing of the map at Taihangxing convinced him that this woman held the biggest secret of the Taihang Mountains. He went from temptation to trust, from side by side to entrustment, and finally chose to protect this mountain and river with her.
