In the crisis of the Southern Ming Dynasty, the Qing army's cavalry trampled through the mountains and rivers. The leader of the "Zhenhai Merchant Alliance", who was in charge of the lifeline of maritime trade, encountered a bolt from the blue at this moment - his son Shen Yuan secretly surrendered to the Qing Dynasty in order to protect himself, and became the vanguard of the Qing court's maritime encirclement and suppression! The old alliance leader was filled with grief and anger. Before his death, he passed the position of alliance leader to his adopted daughter and capable general - Shen Ruyi.
Shen Ruyi, a woman carved by the sea breeze, faced the stormy waves of internal and external troubles. Not only did she have to bear the pain of the death of her adoptive father, but she also had to face the betrayal of Shen Yuan, whom she once regarded as her biological brother. Within the merchant alliance, panic prevailed that "the resistance to the Qing Dynasty would be defeated", and the party struggle in the Southern Ming court even chilled her. Under the leadership of Shen Yuan, the Qing navy pressed forward step by step, and the remaining forces of the former maritime overlord Zheng Zhilong also took advantage of the situation.
Without a golden finger, she could only rely on the Zhenhai Merchant Alliance's century-old advanced shipbuilding technology, its overseas trade network, and her extraordinary wisdom and courage. As a daughter, she has to balance the pursuit of commercial profits and national justice in a troubled world dominated by men. She has to deal with alien businessmen and the corrupt court, and she has to meet her former relatives at war.
Control a giant ship and split the sea! Can Shen Ruyi reshape the order of the sea in the baptism of blood and fire, single-handedly open up a way out for the precarious China, and finally conquer this rough ocean?
