Crossing the Ages: Dragon's Map

A modern soul unexpectedly transmigrates into Zhao Chen, a lowly shepherd slave on the grasslands of Linhuang in the Liao realm, whose life is worth no more than grass. Just as he escapes the dead end of being sold, he is accidentally swept into a succession struggle within the Yelü Shulü clan. The eldest son, Yelü Hongxian, is cruel and bloodthirsty, treating human lives like insects; the second son, Yelü Hongze, is gentle and reserved, yet struggles at every turn amid the family's power struggles.

To protect himself, Zhao Chen uses his modern management knowledge to sort out the Yelü household's accounts, only to stumble upon shocking evidence that Yelü Shulü is smuggling warhorses to Western Xia. In a moment of crisis, he meets Su Qiao, a descendant of the Mohist school who is disguised as an embroiderer. He learns basic mechanical techniques and uses simple devices of his own making to overcome several deadly crises. He also sets a clever trap in the account books, publicly exposing Yelü Hongxian's embezzlement of military funds and winning Yelü Hongze's wholehearted trust.

But standing out too much can invite death. Yelü Hongxian's murderous schemes are already taking shape in the shadows, while the bronze mirror Zhao Chen happened to obtain seems to reveal a vision of Jin forces marching south and Bianjing in peril. The power struggle within the household is far from over, and the nation is already in crisis. Can this transmigrator, armed with modern knowledge and Mohist mechanical skills, survive the twin threats of the grasslands and the imperial court, and change the fate of the Great Song as it teeters on the brink of collapse?
