Mrs. Salt Owl

Su Wanqing, the daughter of a salt merchant in the south of the Yangtze River, was married into her enemy Baifu as a concubine after her family was ruined. With her extraordinary wisdom and talent in mathematics, she hid in a deep house and secretly investigated the truth behind her father's unjust case. In the game and testing with Bai Yanxing, the head of the Bai family, she gradually uncovered layers of conspiracies and discovered that her father's death was actually involved in corruption in water transportation, official collusion and even royal secrets. In this chess game full of lies and betrayal, she grew from a chess piece to a chess player, and finally used the salt account as a blade to split the fog and rewrite the salt-cao pattern in the south of the Yangtze River.
