Shen Zhiwei transformed into a sickly princess who was sent to the north. Everyone thought she would not be able to survive the cold winter. However, she used the medicine bag as a key and the loom as a sword to quietly weave an industrial network covering pastoral areas, trade routes and military supplies on the ice sheet. Tuoba Lie went from killing her to protecting her, and Su Yingxue struggled between betrayal and redemption. Chi Ling's secret technique, Adun's blood letter, and Gu's old conspiracy all became her breaking point. When the Southern Dynasty forced her to surrender by cutting off food, she burned all the account books with a smile - this northern territory was no longer anyone's chessboard, but her world.
